Description

Carrier processing method and user equipment

technical field

The embodiments of the present invention relate to the communication field, and in particular, to a carrier wave processing method and user equipment.

Background technique

Existing communication systems can aggregate multiple carriers, that is, by simultaneously scheduling resources of multiple carriers to a user equipment (User Equipment, hereinafter referred to as: UE), so as to support wider bandwidth and meet higher peak rates and Business needs.

In order to achieve the power saving purpose of the UE, the existing carrier aggregation may use a discontinuous reception (Discontinuous Reception, hereinafter referred to as: DRX) mechanism. Common DRX (hereinafter referred to as: CommonDRX) is one of the DRX mechanisms. In the CommonDRX mechanism, at the beginning of the DRX cycle, if each carrier, including the main carrier and non-main carrier, does not receive data during the timing of the on-duration timer (hereinafter referred to as: OnDurationTimer), all carriers are deactivated. If within the timing time of OnDurationTimer, the main carrier is always in active state. When the UE receives data on the main carrier, it can start the DRX inactivity timer (hereinafter referred to as: InactivityTimer), and all non-main carriers are also activated. When the timing of InactivityTimer ends, that is, when the DRX cycle ends, all carriers , including both the main carrier and the non-main carrier are deactivated.

In the prior art, under the CommonDRX mechanism, different carriers may have different scheduling times, which may cause power waste.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Fig. 1 is a flowchart of an embodiment of the carrier processing method of the present invention, as shown in Fig. 1, the method of this embodiment may include:

Step 101. Start a timer for each carrier in the activated state among the aggregated carriers.

For example, after any carrier in the aggregated carriers enters the active state, the UE can start a timer for the carrier, so the UE can start timers for multiple carriers respectively.

Specifically, it is assumed that a total of four carriers provide services for the UE, namely CC1, CC2, CC3 and CC4. In the existing technology, assuming that CC1 is the main carrier, CC1 can be in the active state during the DRX cycle, and when the UE receives data on CC1, the UE needs to start InactivityTimer, and all non-main carriers are also activated. When the InactivityTimer expires, all carriers, including primary carriers and non-primary carriers, are deactivated. However, due to different carriers, their scheduling time may be different, that is, after the non-main carrier is activated, not all non-main carriers have data transmission, and all non-main carriers can only be transmitted at the end of the DRX cycle For the case where no main carrier is set, the activation mode of each carrier is more flexible, however, each carrier can only be deactivated uniformly at the end of the DRX cycle. Therefore, when there is no data transmission on a certain carrier, the UE's power will be wasted when it is in an active state.

Correspondingly, in this embodiment, the UE may start a timer for the activated carrier. For example, in the case of CC1 as the primary carrier, after the UE receives data on CC1, CC2 to CC4 are activated, and the UE can start timers for CC2 to CC4 respectively. The timer is used to control the deactivation time of CC2-CC4. For the case where the main carrier is not set, the activation time of CC1-CC4 may be the same or different. Therefore, after each carrier in CC1-CC4 is activated, the UE may respectively start timers for these activated carriers.

Step 102: Detect whether the carrier that starts the timer receives data within the time counted by the timer.

For example, in the case of CC1 as the primary carrier, the UE can detect whether there is data transmission on the activated CC2-CC4; in the case that the primary carrier is not configured, the UE can detect whether there is data transmission on CC1-CC4.

Step 103 , if the carrier for which the timer is started does not receive data within the timing of the corresponding timer, deactivate the carrier.

The UE can check whether the data is received on the activated carrier, such as CC2~CC4, within the timing time of the timer. If the UE does not receive data on CC2 within the timing time, the UE can check the timing of the timer corresponding to CC1. When the time is up, CC2 is deactivated. Similarly, if the UE does not receive data on CC3 or CC4 within the counting time, the UE may deactivate CC3 or CC4 respectively when the counting time of the timer corresponding to CC3 or CC4 arrives. Those skilled in the art can set the timing duration of the timer as required. Moreover, the carrier in this embodiment may include a physical downlink control channel (PhysicalDownlinkControlChannel, PDCCH for short) and a physical downlink shared channel (PhysicalDownlinkSharedChannel, PDSCH for short).

It should be noted that this embodiment does not limit the activation mode of each carrier. Those skilled in the art can use any activation mode to activate each carrier. Therefore, the activation time of each carrier can be the same or different. It is only necessary to start a timer according to the activation time of each carrier.

In this embodiment, the UE can start timers for the activated carriers respectively, and if the carrier does not receive any data within the time limit of the timer, the carrier will be deactivated, so as to avoid the occurrence that no data is received on the carrier The problem of being in the active state all the time in the case of the UE, therefore, reduces the power consumption of the UE. Moreover, the carrier without data transmission does not need to wait until the end of the DRX cycle to be deactivated. Therefore, the deactivation mode of the carrier is more flexible.

Specifically, the embodiment of the present invention may adopt five implementation manners to implement the embodiment of the carrier processing method shown in FIG. 1 , which will be described in sequence below.

Wherein, the following manners 1 and 2 can respectively start a non-restart timer for each carrier that enters the activated state, and the non-restart timer does not perform a restart operation when the corresponding carrier receives data. Modes 3 and 4 may respectively start a restart timer for each carrier that enters the active state, and the restart timer performs a restart operation when the corresponding carrier receives data. In the fifth way, a non-restart timer can be started for each carrier entering the active state, and a common restart timer can be set for all carriers entering the active state.

Specifically, the implementation schemes of each method are as follows:

Method 1 may include:

1) After the carrier enters the active state, start a non-restart timer for the carrier.

2) Detecting whether the carrier receives data within the timing time of the non-restart timer.

3) If the carrier does not receive data within the timing of the timer, deactivate the carrier; if the carrier receives data within the timing of the non-restart timer, stop the The timing operation of the non-restart timer, and deactivating the carrier when the DRX inactivation timer times out.

In this implementation, the timer started by the UE for the activated carrier is a non-restart timer, that is, once the non-restart timer is started, when the carrier subsequently receives data, the non-restart timer will not restart timing, but stops the timing operation.

For example, assuming that CC1 is the main carrier, CC1 is active throughout the DRX cycle. When CC1 receives data, CC2~CC4 are activated. At this time, the UE can start non-restart timers for CC2~CC4 respectively. . Assuming that CC2 receives data within the timing of the non-restart timer, the UE will stop the timing operation of the non-restart timer corresponding to CC2, and CC2 will remain active until the end of the DRX cycle, that is, the main carrier The moment of deactivation is deactivation. Assuming that CC3 has not received any data within the timing of the non-restart timer, the UE may deactivate the CC3 when the timing of the non-restart timer arrives. The processing process for CC4 is similar to the above-mentioned process and will not be repeated here. For the case where the primary carrier is not preset, the deactivation principle of CC1 is similar to the deactivation principle of CC2, CC3 or CC4 above, and will not be repeated here.

Therefore, in this implementation, the UE can start a non-restart timer for the activated carrier respectively, and if the carrier does not receive any data within the timing of the non-restart timer, the UE can deactivate the carrier processing, so as to avoid the problem that the carrier is always in the active state even when no data is received on the carrier, thus reducing the power consumption of the UE. Moreover, for a carrier without data transmission, the UE can deactivate the carrier when the non-restart timer expires, and deactivate the carrier with data transmission after the end of the DRX cycle, so , the deactivation time of each carrier can be flexibly changed according to the data scheduling situation on the carrier.

Method 2 may include:

1) After the carrier enters the active state, start a non-restart timer for the carrier;

2) Detecting whether the carrier receives data within the timing of the non-restart timer;

3) If the carrier does not receive data within the timing of the non-restart timer, then deactivate the carrier; if the carrier receives data within the timing of the non-restart timer, then stop the timing operation of the non-restart timer; start a restart timer for the carrier, and restart the restart timer each time the carrier receives data, when the restart timer or When the DRX inactivation timer times out, the carrier is deactivated.

In this implementation, the timer started by the UE for the activated carrier is a non-restart timer, that is, once the non-restart timer is started, when the carrier receives data, the non-restart timer will not restart , but stops the timing operation, and then the UE starts a restart timer for the carrier, that is, once the restart timer is started, when the carrier receives data later, the restart timer must be restarted every time .

For example, assuming that CC1 is the primary carrier, when CC1 receives data, CC2-CC4 are activated, and at this time, the UE can start non-restart timers for CC2-CC4 respectively. Assuming that CC2 receives the data within the timing of the non-restart timer, the UE will stop the timing operation of the non-restart timer corresponding to CC2 and start a restart timer for CC2. If CC2 is within the restart timer If the data is received within the counting time of the restarting timer, the restarting timer restarts counting. If CC2 does not receive any data within the counting time of the restarting timer, it should be in the restarting timer or DRX inactive timer. When any of them time out, CC2 will be deactivated. Therefore, if CC2 does not receive any data within the timing of the restart timer, when the timing of the restart timer is earlier than the timing of the DRX inactivation timer When it arrives, the deactivation time of CC2 is the arrival time of the restart timer, which is earlier than the arrival time of the DRX inactivation timer, that is, earlier than the end of the DRX cycle. When the DRX When the counting time of the inactive timer reaches earlier than the counting time of the restart timer, the deactivation time of CC2 is the time when the counting time of the DRX inactive timer reaches, that is, the time when the DRX cycle ends. Assuming that CC3 has not received any data within the timing of the non-restart timer, the UE may deactivate the CC3 when the timing of the non-restart timer arrives. The processing process for CC4 is similar to the above-mentioned process and will not be repeated here. For the case where the primary carrier is not preset, the deactivation processing of CC1-CC4 may adopt the processing method of CC2 or CC3, which will not be repeated here.

Therefore, in this implementation, the UE can start a non-restart timer for the activated carrier respectively, and if the carrier does not receive any data within the timing of the non-restart timer, the UE can deactivate the carrier Processing, if the carrier receives data within the timing of the non-restart timer, the UE can start the restart timer for the carrier, only when any timer in the restart timer or the DRX inactive timer times out , and then deactivate the carrier. Therefore, this implementation can reduce the power consumption of the UE, and, for a carrier that has no data transmission within the timing of the non-restart timer, the carrier that receives data within the timing of the non-restart timer and starts the restart type The deactivation time for a carrier that has not received data within the timer's timing and for a carrier that has received data within the non-restarting timer's timing and received data within the restarting timer's timing It can be flexibly changed according to the data scheduling situation on the carrier.

Method 3 may include:

1) After the carrier enters the active state, start a restart timer for the carrier;

2) Detecting whether the carrier receives data within the counting time of the restart timer;

3) If the carrier does not receive data within the timing of the restart timer, deactivate the carrier; if the carrier receives data within the timing of the restart timer, restart the carrier The restart timer, and restart the restart timer each time the carrier receives data, and deactivate the carrier when the restart timer or the DRX inactivation timer times out deal with.

In this implementation, the timer started by the UE for the activated carrier is a restart timer, that is, once the restart timer is started, when the carrier receives data later, the restart timer must be reset each time. Do a reboot.

For example, assuming that CC1 is the main carrier, when CC1 receives data, CC2-CC4 are activated, and at this time, the UE can respectively start restart timers for CC2-CC4. Assuming that CC2 has received the data within the timing of the restart timer, the UE can restart the restart timer so that the restart timer starts timing again. If CC2 does not receive the data within the next timing of the restart timer When any data is received and the timing of the DRX inactivation timer has not yet arrived, the UE can deactivate CC2 when the timing of the restart timer reaches. If the timing of the DRX inactivation timer reaches within the time, the UE also deactivates CC2. Therefore, when the UE restarts the restart timer within each time period of the restart timer, the deactivation time of CC2 is the time when either the restart timer or the DRX inactivation timer times out. Assuming that CC3 has not received any data within the timing of the restart timer, the UE may deactivate the CC3 when the timing of the restart timer arrives. The processing process for CC4 is similar to the above-mentioned process and will not be repeated here.

Therefore, in this implementation, the UE can respectively start a restart timer for the activated carrier, and if the carrier does not receive any data within the timing of the restart timer, the UE can deactivate the carrier, If the carrier receives data within the time of the restart timer, the UE can restart the restart timer, and only when either the restart timer or the DRX inactive timer times out, the UE Perform deactivation processing. Therefore, this implementation can reduce the power consumption of the UE, and deactivate the carriers that have no data transmission within the restart timer time and the carriers that receive data within the restart timer time. The time can be flexibly changed according to the data scheduling situation on the carrier.

Method four may include:

1) Start a restart timer for all carriers after the carrier enters the active state;

2) Detecting whether the carrier receives data within the counting time of the restart timer;

3) If all carriers do not receive data within the timing of the restart timer, all carriers are deactivated; if any carrier in all carriers receives data within the timing of the restart timer, then Restart the restart timer, and when any carrier in all carriers receives data again, restart the restart timer, and when the restart timer or the DRX inactive timer times out, the The carrier is deactivated.

In this implementation, the UE starts a restart timer for all activated carriers, that is, once the restart timer is started, when any carrier in all carriers receives data, the UE will start the restart timer reboot.

For example, assuming that CC1 is the primary carrier, when CC1 receives data, CC2-CC4 are activated, and at this time, the UE can start a restart timer for CC2-CC4. Then, when any carrier in CC2~CC4 receives data, the UE will restart the restart timer, so that the restart timer will perform the timing operation again, until one of the restart timer and the DRX inactivation timer times out, the UE That is, all carriers are deactivated. When the primary carrier is not pre-set, all CC1-CC4 may adopt the above deactivation process.

Therefore, in this implementation, the UE can maintain a restart timer for all activated carriers, and if no carrier receives data within the time limit of the restart timer, the UE can deactivate all carriers , if a carrier receives data within the time of the restart timer, the UE can restart the restart timer, and only when either the restart timer or the DRX inactive timer times out, the UE The carrier is deactivated. Therefore, this implementation can reduce the power consumption of the UE.

Way five can include:

1) After the carrier enters the active state, start a non-restart timer for each carrier in all carriers, and set a common restart timer for all carriers;

2) Detecting whether the carrier receives data within the timing of the non-restart timer;

3) If the carriers do not receive data within the timing of their respective non-restart timers, deactivate the non-main carriers that have not received data; If no data is received, all carriers are deactivated; if the respective non-restart timers of all carriers are started, and when data is received for the first time on any carrier before the non-restart timer expires, then Start the restart-type timer, and stop the timing operation of the non-restart-type timer corresponding to the carrier receiving the data; after the restart-type timer is started, the restart-type The timer restarts; and after the restart timer is started, the non-restart timer stops the timing operation after receiving data on the corresponding carrier or timing overtime, and when the corresponding non-restart timer times out, or all carriers share When the restart timer of DRX expires, or the DRX inactivation timer expires, the carrier is deactivated

For example, assuming that CC1 is the primary carrier, when CC1 receives data, CC2-CC4 are activated, and at this time, the UE can start non-restart timers for CC2-CC4 respectively. Assuming that CC2 receives the data within the timing of its corresponding non-restart timer, the UE will stop the timing operation of the non-restart timer corresponding to CC2 and start the restart timer. UE is jointly maintained by CC2~CC4 A restart timer. If CC2 receives data again within the timing of the restart timer, the restart timer restarts timing, and if CC3 receives data within the timing of the corresponding non-restart timer, UE will also The counting operation of the non-restart timer corresponding to CC3 is stopped, and the restart timer is restarted. Therefore, in this implementation, when the UE receives data on the CC2~CC4 for the first time, the restart timer will be started, and every time the subsequent CC2~CC4 receives data, the restart timer will be started. Restart, and deactivate all carriers until no data is received on CC2-CC4 and any one of the restart timer or the DRX inactivation timer times out. For the case where the primary carrier is not preset, the deactivation processing of CC1-CC4 may adopt the processing manner of CC2-CC4, which will not be repeated here.

Therefore, in this implementation, the UE can start a non-restart timer for the activated carrier respectively, and if the carrier does not receive any data within the timing of the non-restart timer, the UE can deactivate the carrier Processing, if the carrier receives data within the timing of the non-restart timer, the UE restarts the restart timer commonly maintained for all carriers, only in any timer in the restart timer or DRX inactive timer When timeout occurs, all carriers are deactivated. Therefore, this implementation can reduce the power consumption of the UE, and, for the situation that there is no data transmission within the timing of the non-restart timer, or the data is received within the timing of the non-restart timer and the restart of the restart The case where no data is received by all carriers within the countdown time of the non-restart timer and the case where data is received within the countdown time of the non-restart timer and any carrier receives data within the countdown time of the restarted timer In other words, its deactivation time can be flexibly changed according to the data scheduling situation on the carrier.

It should be noted that, none of the above-mentioned implementation methods restricts the activation methods of each carrier, and those skilled in the art can use any activation method in the prior art for processing. The above-mentioned implementation methods only limit how to The deactivation process is performed according to the data scheduling situation on each carrier.

FIG. 2 is a flowchart of another embodiment of the carrier processing method of the present invention. As shown in FIG. 2, the method of this embodiment may include:

Step 201: Receive medium access control (MediaAccessControl, hereinafter referred to as: MAC) layer extension signaling, obtain the carrier identifier and corresponding operation bit contained in the MAC layer extension signaling, and the operation bit is used to indicate that the carrier is activated Or deactivate the operation.

For example, the UE may receive MAC layer extended signaling, such as MACCE extended signaling, which may include a carrier identifier and an operation bit corresponding to the carrier identifier, wherein the operation bit may indicate that the UE is compatible with the corresponding carrier The corresponding carrier is identified to be activated or deactivated.

Specifically, in this embodiment, the MACCE may be extended, so that the extended MACCE is used to indicate the bitmap of the carrier. For an inactive carrier, the carrier identifier included in the MACCE extended signaling corresponds to the inactive carrier, and the corresponding operation bit is to instruct the UE to activate the carrier. For an activated carrier, the carrier identifier included in the MACCE extended signaling corresponds to the activated carrier, and the corresponding operation bit is to instruct the UE to deactivate the activated carrier.

It should be noted that, this embodiment may also use existing MACCE signaling, for example, MACCE signaling under the R8 protocol. When the UE receives the MACCE signaling, it can activate or deactivate all carriers at the same time, or activate or deactivate all non-principal carriers when the primary carrier is set.

Step 202: Perform a carrier processing operation corresponding to the operation bit on the carrier corresponding to the carrier identifier.

After receiving the MAC layer extension signaling, the UE may perform a carrier processing operation corresponding to the pre-operation bit on the carrier corresponding to the carrier identifier. For example, the carrier identifier contained in the MACCE extended signaling is K1, and its corresponding operation bit is 0, which represents a deactivation operation, and the UE can deactivate the carrier corresponding to K1. The carrier identifier included in the MACCE extended signaling is K2, and its corresponding operation bit is 1, which represents an activation operation, so the UE can activate the carrier corresponding to K2.

In view of the difference in the time when the UE receives the MAC layer extension signaling, the UE can activate or deactivate the carrier at different times, so as to control the activation or deactivation state of the carrier.

In this embodiment, the MAC layer extended signaling is used to indicate the activation or deactivation of the carrier with a bitmap, so that the UE can flexibly activate or deactivate the carrier according to the MAC layer extended signaling without causing the carrier to In the active state, thereby reducing the power consumption of the UE.

Further, the carrier identifier included in the MAC layer extension signaling may be the frequency identifier of the carrier from low frequency to high frequency or from high frequency to low frequency, or the number of the carrier, so that the UE can Different numbers are activated or deactivated one by one, so this operation is more convenient.

FIG. 3 is a flowchart of another embodiment of the carrier processing method of the present invention. As shown in FIG. 3, the method of this embodiment may include:

Step 301. When data is received on the main carrier for the first time, activate a first-type non-main carrier of the same type as the main carrier.

For example, when the UE receives data on the primary carrier for the first time, it may perform activation processing on the first-type non-principal carrier that is the same type as the primary carrier.

Specifically, the carrier types may include PDCCH and PDSCH. If the preset primary carrier is a certain PDCCH carrier, the UE may activate other PDCCH non-primary carriers after receiving data on the PDCCH primary carrier. If the preset primary carrier is a certain PDSCH carrier, after the UE receives data on the PDSCH primary carrier, it can activate other PDSCH non-primary carriers.

Step 302: When data is received on any carrier in the activated first-type non-main carrier, activate the second-type non-main carrier.

For the case where the preset main carrier is a PDCCH carrier, in step 301, PDCCH non-main carriers in all non-main carriers are activated, and data scheduling can be performed on these activated PDCCH non-main carriers. When any one of the activated PDCCH non-principal carriers receives data, the UE may activate the remaining PDSCH non-principal carriers among all the non-principal carriers.

For the case where the preset main carrier is a PDSCH carrier, in step 301, PDSCH non-main carriers in all non-main carriers are activated, and data scheduling can be performed on these activated PDSCH non-main carriers. When any one of the activated PDSCH non-principal carriers receives data, the UE may activate the remaining PDCCH non-principal carriers among all the non-primary carriers.

In this embodiment, the carriers that need to be activated can be divided into main carriers and non-main carriers. For non-main carriers, they can be divided into the first type of non-main carrier and the second type of non-main carrier that are the same type as the main carrier. , when the UE receives data on the main carrier, the UE can activate the first type of non-main carrier of the same type as the group carrier, and only when the UE receives data on the first type of non-main carrier, the second Therefore, this embodiment can activate the carriers in stages. During the activation process, the scheduling situation on different carriers can be fully considered without activating all carriers at the same time. Therefore, The power consumption of the UE is reduced, and, compared with the prior art, its activation mode is more flexible.

FIG. 4 is a flowchart of another embodiment of the carrier processing method of the present invention. As shown in FIG. 4, the method of this embodiment may include:

Step 401: Receive a cross-carrier scheduling instruction sent by a base station on a primary carrier, where the cross-carrier scheduling instruction is used to schedule an activated Physical Downlink Control Channel (PDCCH) non-primary carrier.

For example, in this embodiment, a primary carrier may be preset, and the base station may perform data scheduling on the primary carrier. When the base station needs to perform data scheduling on a certain non-main carrier, the base station may send a cross-carrier scheduling indication to the UE on the main carrier. In this embodiment, the UE may receive the cross-carrier scheduling indication sent by the base station on the primary carrier. In this embodiment, the main carrier may be a PDCCH carrier or a PDSCH carrier. The cross-carrier scheduling instruction is used to schedule the activated PDCCH non-main carrier, that is, the base station sends the cross-carrier scheduling instruction for scheduling the PDCCH non-main carrier on the main carrier.

Step 402: According to the cross-carrier scheduling instruction, perform PDCCH blind detection processing on the PDCCH non-main carrier.

In the prior art, if the non-main carrier is configured as PDSCH, no PDCCH blind detection is performed on the PDSCH non-primary carrier; if the non-primary carrier is configured as PDCCH, the UE needs to perform blind detection on the PDCCH detection, so as to obtain downlink control information and so on. However, when the number of PDCCHs in the configured non-main carrier is large, the UE consumes a considerable amount of power when performing blind detection.

Therefore, in this embodiment, the first data scheduling of each PDCCH non-main carrier can be completed by the main carrier through the cross-carrier scheduling instruction. When the UE receives the cross-carrier scheduling instruction sent by the base station on the main carrier, the UE can Perform blind detection on the PDCCH non-main carrier according to the cross-carrier scheduling instruction. Before that, the PDCCH non-main carrier only receives data without performing blind detection.

In the specific implementation process, the cross-carrier scheduling instruction may carry the identification information of the PDCCH non-main carrier that needs to be scheduled, so that the UE only performs blind detection processing on the PDCCH non-primary carrier corresponding to the identification information, while other PDCCH non-primary carriers Still only data is received without blind detection processing. The cross-carrier scheduling instruction may not carry any PDCCH non-primary carrier identification information. The cross-carrier scheduling instruction is only used as a trigger message. The main carrier performs blind detection processing.

In this embodiment, only when the PDCCH as a non-main carrier receives a cross-carrier scheduling instruction, the UE starts to perform blind detection on the PDCCH instead of performing blind detection on the PDCCH all the time, thereby reducing the power consumption of the UE.

FIG. 5 is a flowchart of another embodiment of the carrier processing method of the present invention. As shown in FIG. 5, the method of this embodiment may include:

Step 501: Receive an indication message sent by a base station on a carrier in an activated state, where the indication message includes identification information of a carrier that needs to be activated.

For example, the UE may receive the indication message sent by the base station on the carrier in the activated state.

Specifically, in the prior art, for the independent DRX (hereinafter referred to as: IndependentDRX) mechanism, since the InactivityTimer of each carrier needs to be started separately, and the time that each carrier is in the active state may be different, if one of the carriers is active state, but other carriers are not in the active state, the base station, such as eNB, can only schedule the active carrier, and only after the OnDurationTimer of other carriers is started, other carriers can be scheduled. Therefore, in the prior art, since each carrier needs to independently maintain its own InactivityTimer, the scheduling flexibility of the base station is limited when scheduling these carriers.

In this embodiment, the base station may send an indication message to the UE on the carrier in the activated state, and the indication message may include identification information of the carrier that needs to be activated, and the identification information may be the serial number of the carrier, or may be the number of the carrier frequency identifier.

Step 502: Activate the carrier corresponding to the identification information.

The UE may activate the carrier corresponding to the identification information according to the identification information, so that the base station may perform data scheduling on the carrier activated by the UE.

For example, when the carrier CC1 is in the active state and CC2 is in the inactive state, the base station needs to schedule CC2, then the base station can send an indication message on CC1 to notify the UE to start the InactivityTimer of CC2, so that CC2 enters the active state.

It should be noted that, in this embodiment, the indication message may be in a special PDCCH format, or may be a MACControlElement by using a special value in an existing PDCCH format. Moreover, in the indication message, one or more carriers in the inactive state may be instructed to start the InactivityTimer at the same time, so as to enter the active state and wait for receiving the scheduling information of the base station.

In this embodiment, the base station may send an indication message on the activated carrier, through which the UE is instructed to activate the inactive carrier that the base station needs to schedule, so that the base station can perform data scheduling on the activated carrier . Therefore, in this embodiment, the base station can flexibly schedule any carrier through the indication message.

Fig. 6 is a flow chart of yet another embodiment of the carrier wave processing method of the present invention. As shown in Fig. 6, the method of this embodiment may include:

Step 601: Receive data on the primary carrier, and configure semi-persistent scheduling on the primary carrier.

For example, the primary carrier may be always in an active state during the DRX cycle, so the base station can perform data scheduling on the primary carrier, and the UE can receive data scheduled by the base station on the primary carrier.

Step 602: If the time when data is received for the first time on the main carrier is the time of semi-static data scheduling, activate processing on the non-main carrier when the main carrier receives data next time.

The UE may determine whether the time when data is received for the first time on the primary carrier is the time for semi-static data scheduling. The so-called semi-static data scheduling time may refer to the data periodically scheduled by the base station on the activated primary carrier. If the UE judges that the moment when it receives data for the first time on the main carrier is the time of semi-static data scheduling, then the UE does not activate any non-main carrier at this time, but waits for the next time when the main carrier receives data again, and then Activation processing is performed on the non-main carrier.

Further, if the UE judges that the time when the data is received is not the time for static data scheduling, the UE may activate the non-main carrier.

In this embodiment, the UE can control the activation time of the non-principal carrier by judging whether the moment when the primary carrier receives data for the first time is the time of semi-static data scheduling, so that the non-primary carrier can be activated flexibly, and The UE will not activate the non-main carrier after the main carrier receives the data. Therefore, in this embodiment, when the first data received by the main carrier is semi-static data, the activation time of the non-main carrier can be reduced, thereby Realize the effect of reducing power loss.

FIG. 7 is a flowchart of another embodiment of the carrier processing method of the present invention. As shown in FIG. 7, the method of this embodiment may include:

Step 701 , in the first n frames of semi-persistent scheduling, determine the status information of carriers that need to receive semi-persistent scheduling data, where n≤4.

Specifically, the UE may know the period of the semi-persistent scheduling in advance. In the first n frames of the semi-persistent scheduling, the UE may predetermine the status information of the carriers that need to receive the semi-persistent scheduling data, so as to determine whether the carriers that need to receive the semi-persistent scheduling data can receive the semi-persistent scheduling data.

Step 702: If the state information of the carrier is the deactivated state, perform activation processing on the carrier, so that the activated carrier receives the semi-persistent scheduling data.

If the UE determines that the carrier that needs to receive semi-persistent scheduling data is in the activated state, the UE may not perform any operations, but waits to receive semi-persistent scheduling data on the carrier; if the UE determines that the carrier that needs to receive semi-persistent scheduling data is In the activated state, the UE can activate the carrier in advance, so as to ensure the semi-persistent scheduling time, and the UE can receive the semi-persistent scheduling data on the activated carrier.

It should be noted that, in order to ensure that the corresponding carrier must be in the activated state at the time of semi-persistent scheduling, those skilled in the art can adjust the size of n appropriately according to the needs. If the value of n is larger, the activation process is more reliable, but the carrier The time in the active state will be longer, and the power consumption of the UE will be more. Therefore, those skilled in the art can adjust the value of n by weighing various indicators.

In this embodiment, semi-persistent scheduling can be configured on any carrier, so the UE can determine whether the current state of the carrier that needs semi-persistent scheduling is activated or deactivated several frames in advance, and if it is in the deactivated state, perform Activate processing. In this embodiment, the carrier can be flexibly activated according to the time of semi-persistent scheduling, instead of keeping the carrier in an activated state waiting to receive semi-persistent scheduling data, thereby shortening the activation time of the carrier and reducing the power consumption of the UE.

Based on all the above embodiments, it can be seen that the technical solutions of the embodiments of the present invention respectively propose new processing methods for the activation processing of the carrier, the processing after the activation of the non-main carrier, and the deactivation processing of the carrier. In the carrier aggregation scenario, the embodiment of the present invention may combine any of the above methods with the existing technology, or combine the above methods. The optional ways of activation processing, the optional ways of non-main carrier activation processing and the optional ways of carrier deactivation processing are firstly listed below, and then various combination schemes are described.

1. Options for Activation Processing

1) A solution in which all carriers are simultaneously activated in the prior art;

2) The implicit activation scheme in the prior art: the primary carrier is always in an activated state during the DRX cycle, and when the UE receives data on the primary carrier for the first time, all non-principal carriers are activated;

3) The display activation scheme provided by the embodiment of the present invention, for the specific scheme, refer to the scheme of the embodiment shown in FIG. 2 ;

4) The classification activation scheme provided by the embodiment of the present invention, for the specific scheme, refer to the scheme of the embodiment shown in Figure 3;

5) The activation scheme shown in Figure 6 provided by the embodiment of the present invention;

6) The activation scheme shown in FIG. 7 provided by the embodiment of the present invention.

2. The solution for energy-saving processing after the PDCCH of the non-primary carrier is activated. For details, refer to the solution of the embodiment shown in FIG. 4 .

3. Options for deactivation processing

1) In the prior art, at the end of the DTX period, all carriers are deactivated.

2) The first deactivation processing method in the embodiment shown in FIG. 1 above;

3) The second deactivation processing method in the embodiment shown in FIG. 1 above;

4) The third deactivation processing method in the embodiment shown in FIG. 1 above;

5) The fourth deactivation processing method in the embodiment shown in FIG. 1 above;

6) The deactivation processing mode five in the embodiment shown in the above-mentioned FIG. 1;

7) The display deactivation processing solution in the above embodiment shown in FIG. 3 .

Therefore, in the overall scheme of carrier wave processing, the activation processing method can choose one of the above-mentioned six activation processing schemes, and the deactivation processing method can choose one of the above-mentioned seven deactivation processing schemes. , by combining the selected activation processing scheme and the deactivation processing scheme, a complete scheme for activating and deactivating the carrier can be obtained. It should be noted that, in order to ensure that the combined technical solution introduces the new technical solution provided by the embodiment of the present invention, if the existing technical solution in the above-mentioned activation processing solution is selected, it is necessary to select this technical solution in the deactivation processing solution. For the new deactivation processing solution provided by the embodiment of the invention, if the prior art solution in the above deactivation processing solution is selected, then the activation processing solution needs to select the new activation processing solution provided by the embodiment of the present invention. For the processing solution of the non-principal carrier after activation, it is an optional solution in the complete combined solution. When the activated processing solution of the non-principal carrier is introduced into the combination solution, both the activation processing solution and the inactivation processing solution can choose the prior art solution. Moreover, for each carrier that simultaneously provides services for the UE, the above-mentioned combinations of different technical solutions may be adopted. According to the above description, those skilled in the art can combine activation and deactivation schemes as needed.

To select the second) scheme in the activation processing optional scheme, adopt the energy-saving processing scheme for the PDCCH carrier of the non-main carrier, adopt the second) scheme in the deactivation processing scheme for the PDCCH carrier of the non-main carrier, and use the PDCCH carrier for the PDCCH carrier. The third) scheme in the deactivation treatment scheme. Fig. 8 is a timing relationship diagram of yet another embodiment of the carrier processing method of the present invention. As shown in Fig. 8, the main carrier CC1 is always in the active state during the DRX cycle. When the UE receives data on the main carrier CC1, the carrier CC2 ~CC5 is activated, and the UE starts timers for CC2~CC5 respectively, among which CC2 and CC4 are PDCCH carriers, CC3 and CC5 are PDSCH carriers, so UE starts non-restart timers for CC2 and CC4, which are CC3 and CC5 What starts is a restart timer. When the UE receives data on CC2 and CC3, the non-restart timer corresponding to CC2 stops counting, and in the DRX cycle technology, that is, when the InactivityTimer expires, the UE deactivates CC2; The restart timer corresponding to CC3 performs the restart operation. During the timing of the subsequent InactivityTimer, the UE only receives data on CC1. Therefore, when CC3 reaches the timing again after restarting the restart timer, the UE deactivates the CC3. For CC4 and CC5, since the UE receives any data on CC4 and CC5 within the timing of their respective timers, the UE will receive data when CC4 and CC5 arrive at the timing of their respective timers. , deactivate CC4 and CC5.

Therefore, it can be seen from FIG. 8 that the UE can start timers for the activated carriers respectively, and if the carrier does not receive any data within the time limit of the timer, the carrier will be deactivated. Therefore, the UE can The activation time of the carrier is controlled according to the data scheduling situation on different carriers. As shown in FIG. 8 , each carrier is not in the active state in the entire DRX cycle. Therefore, this embodiment reduces the power consumption of the UE. Moreover, as shown in Figure 8, the deactivation time of each carrier can be different, and the carrier that has no data transmission from the beginning to the end does not need to wait until the end of the DRX cycle before being deactivated. Therefore, the deactivation method of the carrier in this embodiment More flexible. Moreover, in this embodiment, the non-main carrier PDCCH carriers, that is, CC2 and CC4 adopt an energy-saving scheme, and only when receiving the cross-carrier scheduling instruction sent by the main carrier CC1, the UE starts to perform blind detection on the CC2 and CC4 , instead of performing blind detection on the CC2 and CC4 all the time, thereby reducing the power consumption of the UE.

Those of ordinary skill in the art can understand that all or part of the steps for realizing the above-mentioned method embodiments can be completed by hardware related to program instructions, and the aforementioned program can be stored in a computer-readable storage medium. When the program is executed, the It includes the steps of the above method embodiments; and the aforementioned storage medium includes: ROM, RAM, magnetic disk or optical disk and other various media that can store program codes.

FIG. 9 is a schematic structural diagram of an embodiment of the user equipment of the present invention. As shown in FIG. 9, the UE of this embodiment may include: an activation module 11 and a processing module 12, wherein the activation module 11 is used to The carrier starts the timer; the processing module 12 is used to detect whether the carrier that starts the timer receives data within the timing of the timer, and the corresponding timer that the carrier that starts the timer starts at the start module When no data is received within the counting time, the carrier is deactivated.

The implementation principle of the UE in this embodiment is similar to the implementation principle of the method embodiment shown in FIG. 1 , and will not be repeated here.

In this embodiment, the UE can start timers for the activated carriers respectively, and if the carrier does not receive any data within the time limit of the timer, the carrier will be deactivated, so as to avoid the occurrence that no data is received on the carrier The problem of being in the active state all the time in the case of the UE, therefore, reduces the power consumption of the UE. Moreover, the carrier without data transmission does not need to wait until the end of the DRX cycle to be deactivated. Therefore, the deactivation mode of the carrier is more flexible.

Further, there are five implementations of the startup module 11 and the processing module 12 . Wherein, in the following ways 1 and 2, the starting module 11 can respectively start a non-restart timer for each carrier that enters the active state, and the non-restart timer does not perform a restart operation when the corresponding carrier receives data. In mode 3 and mode 4, the starting module 11 may respectively start a restart timer for each carrier that enters the active state, and the restart timer performs a restart operation when the corresponding carrier receives data. In the fifth manner, the starting module 11 may start a non-restart timer for each carrier that enters the active state, and set a common restart timer for all carriers that enter the active state.

Specifically, the implementation schemes of various methods are as follows:

Method 1: The starting module 11 is used to start a non-restart timer for the carrier; the processing module 12 is used to delete the carrier when the carrier does not receive data within the timing of the non-restart timer. Activation processing, when the carrier receives data within the timing of the non-restart timer, stop the timing operation of the non-restart timer, so that the deactivation time of the carrier and the deactivation time of the main carrier are kept unanimous.

In this manner, the processing of the activation module 11 and the processing module 12 corresponds to the implementation manner 1 of the deactivation processing method, which will not be repeated here.

In this implementation, the UE can respectively start a non-restart timer for the activated carrier, and if the carrier does not receive any data within the timing of the non-restart timer, the UE can deactivate the carrier. Therefore, the problem that the carrier is always in the active state even when no data is received on the carrier is avoided, thereby reducing the power consumption of the UE. Moreover, for a carrier without data transmission, the UE can deactivate the carrier when the non-restart timer expires, and deactivate the carrier with data transmission after the end of the DRX cycle, so , the deactivation time of each carrier can be flexibly changed according to the data scheduling situation on the carrier.

Method 2: The starting module 11 is used to start a non-restart timer for the carrier; the processing module 12 is used to delete the carrier when the carrier does not receive data within the timing of the non-restart timer. Activation processing, when the carrier receives data within the timing time of the non-restart timer, stop the timing operation of the non-restart timer; start the restart timer for the carrier, and every time the carrier When data is received for the first time, the restart timer is restarted, and when the restart timer or the discontinuous reception DRX inactivation timer times out, the carrier is deactivated.

In this manner, the correspondence between the processing of the starting module 11 and the processing module 12 and the implementation manner 2 of the deactivation processing method will not be repeated here.

In this implementation, the UE can respectively start a non-restart timer for the activated carrier, and if the carrier does not receive any data within the timing of the non-restart timer, the UE can deactivate the carrier. If the carrier receives data within the timing of the non-restart timer, the UE can start the restart timer for the carrier. Only when either the restart timer or the DRX inactive timer expires, the UE Deactivate the carrier. Therefore, this implementation can reduce the power consumption of the UE, and, for a carrier that has no data transmission within the timing of the non-restart timer, the carrier that receives data within the timing of the non-restart timer and starts the restart type The deactivation time for a carrier that has not received data within the timer's timing and for a carrier that has received data within the non-restarting timer's timing and received data within the restarting timer's timing It can be flexibly changed according to the data scheduling situation on the carrier.

Mode 3: The starting module 11 is used to start a restart timer for the carrier; the processing module 12 is used to deactivate the carrier when the carrier does not receive data within the time limit of the restart timer , when the carrier receives data within the timing of the restart timer, restart the restart timer, and restart the restart timer each time the carrier receives data, when the When the restart timer or the discontinuous reception DRX inactivation timer times out, the carrier is deactivated.

In this manner, the processing of the activation module 11 and the processing module 12 corresponds to the implementation manner 3 of the deactivation processing method, which will not be repeated here.

In this implementation, the UE can start a restart timer for the activated carrier respectively. If the carrier does not receive any data within the time of the restart timer, the UE can deactivate the carrier. If the carrier receives data within the time limit of the restart timer, the UE can restart the restart timer. Only when either the restart timer or the DRX inactivation timer times out, the carrier will be deactivated. Activate processing. Therefore, this implementation can reduce the power consumption of the UE, and deactivate the carriers that have no data transmission within the restart timer time and the carriers that receive data within the restart timer time. The time can be flexibly changed according to the data scheduling situation on the carrier.

Mode 4: The starting module 11 is used to start a restart timer for all carriers; the processing module 12 is used to respond to the failure to receive data when any carrier in all carriers does not receive data within the timing time of the restart timer. Carrier deactivation processing, when any one of all carriers receives data within the timing of the restart timer, restart the restart timer, and when any one of all carriers receives data again, Restarting the restart timer, when the restart timer or the discontinuous reception DRX inactivation timer times out, deactivate the carrier.

In this manner, the processing of the activation module 11 and the processing module 12 corresponds to the implementation manner 4 of the deactivation processing method, which will not be repeated here.

In this implementation, the UE can maintain a restart timer for all activated carriers. If no carrier receives data within the time of the restart timer, the UE can deactivate all carriers. If If a carrier receives data within the timing of the restart timer, the UE can restart the restart timer, and only when any timer in the restart timer or DRX inactive timer times out, the carrier Perform deactivation processing. Therefore, this implementation can reduce the power consumption of the UE.

Mode 5: The starting module 11 is used to start a non-restart timer for each carrier in all carriers, and set a common restart timer for all carriers; If no data is received within the time limit of the restart-type timer, deactivate the non-primary carriers that have not received data; when all carriers have not received data after the restart-type timer starts and times out, deactivate all carriers Processing: After the respective non-restart timers of all carriers are started, when data is received for the first time on any carrier before the non-restart timer times out, start the restart timer, and stop and receive The timing operation of the non-restart timer corresponding to the carrier of the data; after the restart timer is started, restart the restart timer when data is received on any carrier; and after the restart timer starts , the non-restart timer stops the timing operation after receiving data on the corresponding carrier or timing timeout, when the corresponding non-restart timer times out, or the restart timer shared by all carriers times out, or the DRX inactive timer When timeout occurs, the carrier is deactivated.

In this manner, the correspondence between the processing by the starting module 11 and the processing module 12 and the fifth implementation method of the deactivation processing method will not be repeated here.

In this implementation, the UE can respectively start a non-restart timer for the activated carrier, and if the carrier does not receive any data within the timing of the non-restart timer, the UE can deactivate the carrier. If the carrier receives data within the timing of the non-restart timer, the UE restarts the restart timer commonly maintained for all carriers, only when any timer in the restart timer or the DRX inactive timer times out , and then deactivate all carriers. Therefore, this implementation can reduce the power consumption of the UE, and, for the situation that there is no data transmission within the timing of the non-restart timer, or the data is received within the timing of the non-restart timer and the restart of the restart The case where no data is received by all carriers within the countdown time of the non-restart timer and the case where data is received within the countdown time of the non-restart timer and any carrier receives data within the countdown time of the restarted timer In other words, its deactivation time can be flexibly changed according to the data scheduling situation on the carrier.

As shown in FIG. 10, the UE of this embodiment may include: a receiving and obtaining module 21 and a carrier processing module 22, wherein the receiving and obtaining module 21 is used to The indication message sent by the base station is received on the carrier in the state, and the indication message includes the identification information of the carrier that needs to be activated or deactivated; the carrier processing module 22 is configured to activate the carrier corresponding to the identification information.

The UE in this embodiment may also execute the method steps shown in the method embodiment shown in FIG. 5 . Specifically, the UE in this embodiment may execute the method steps shown in the method embodiment shown in FIG. 2 . Let me repeat.

In this embodiment, the UE may receive an indication message sent by the base station on the activated carrier, and through the indication message, the UE may activate the carrier in the inactive state that the base station needs to schedule, so that the base station can activate the carrier on the activated carrier. data scheduling. Therefore, in this embodiment, the UE can flexibly schedule any carrier according to the instruction of the base station.

FIG. 11 is a schematic structural diagram of another embodiment of the user equipment of the present invention. As shown in FIG. 11 , the UE of this embodiment may include: a first activation processing module 31 and a second activation processing module 32, wherein the first activation processing module 31 When receiving data on the main carrier for the first time, activate the first type of non-main carrier of the same type as the main carrier; the second activation processing module 32 is used to activate the first type of non-main carrier on the main carrier When data is received on any of the carriers, the second type of non-main carrier is activated.

Further, in another embodiment of the user equipment of the present invention, the first activation processing module 31 is configured to perform activation processing on the PDCCH non-principal carrier when receiving data on the physical downlink control channel PDCCH primary carrier for the first time; The activation processing module 32 is configured to perform activation processing on the physical downlink shared channel PDSCH non-main carrier when data is received on the PDCCH non-main carrier. In yet another embodiment of the user equipment of the present invention, the first activation processing module 31 is used to activate the PDSCH non-main carrier when receiving data on the PDSCH main carrier for the first time; the second activation processing module 32 is used to When data is received on the PDSCH non-main carrier, the PDCCH non-main carrier is activated.

The UE in the foregoing embodiments may execute the method steps shown in the method embodiment shown in FIG. 3 , which will not be repeated here.

In the above embodiment, the UE can divide the carriers that need to be activated into primary carriers and non-principal carriers. For non-principal carriers, they can be further divided into the first type of non-principal carrier and the second type of the same type as the primary carrier. Non-main carrier, when the UE receives data on the main carrier, the UE can activate the first type of non-main carrier of the same type as the group carrier, only when the UE receives data on the first type of non-main carrier, then The second type of non-main carrier is activated. Therefore, this embodiment can activate the carriers in stages. During the activation process, the scheduling situation on different carriers can be fully considered without activating all carriers at the same time. , therefore, the power consumption of the UE is reduced, and, compared with the prior art, its activation mode is more flexible.

FIG. 12 is a schematic structural diagram of another embodiment of user equipment according to the present invention. As shown in FIG. 12 , the UE of this embodiment may include: a first receiving module 41 and a blind detection processing module 42, wherein the first receiving module 41 is used to The cross-carrier scheduling instruction sent by the base station is received on the main carrier, and the cross-carrier scheduling instruction is used to schedule the activated physical downlink control channel PDCCH non-main carrier; the blind detection processing module 42 is used to perform according to the cross-carrier scheduling instruction. The PDCCH blind detection process is performed on the PDCCH non-main carrier.

The UE in the foregoing embodiments may execute the method steps shown in the method embodiment shown in FIG. 4 , which will not be repeated here.

In this embodiment, only when the PDCCH as a non-main carrier receives a cross-carrier scheduling instruction, the UE starts to perform blind detection on the PDCCH instead of performing blind detection on the PDCCH all the time, thereby reducing the power consumption of the UE.

FIG. 13 is a schematic structural diagram of another embodiment of the user equipment of the present invention. As shown in FIG. 13 , the UE of this embodiment may include: a second receiving module 51 and a third activation processing module 52, wherein the second receiving module 51 is used to The data is received on the main carrier, and the semi-persistent scheduling is configured on the main carrier; the third activation processing module 52 is used to receive data on the main carrier for the first time when it is the time of semi-persistent data scheduling, when the semi-persistent data is scheduled When the main carrier receives data next time, the non-main carrier is activated.

The UE in the foregoing embodiments may execute the method steps shown in the method embodiment shown in FIG. 6 , which will not be repeated here.

In this embodiment, the UE can control the activation time of the non-principal carrier by judging whether the moment when the primary carrier receives data for the first time is the time of semi-static data scheduling, so that the non-primary carrier can be activated flexibly, and The UE will not activate the non-main carrier after the main carrier receives the data. Therefore, in this embodiment, when the first data received by the main carrier is semi-static data, the activation time of the non-main carrier can be reduced, thereby Realize the effect of reducing power loss.

FIG. 14 is a schematic structural diagram of yet another embodiment of user equipment according to the present invention. As shown in FIG. 14 , the UE in this embodiment may include: a state determination module 61 and a fourth activation processing module 62, wherein the state determination module 61 is used to In the first n frames of the semi-persistent scheduling, determine the status information of the carrier that needs to receive the semi-persistent scheduling data; the fourth activation processing module 62 is used to activate the carrier when the status information of the carrier is in a deactivated state , so that the activated carrier receives the semi-persistent scheduling data.

The UE in this embodiment may also execute the method steps shown in the method embodiment shown in FIG. 7 , which will not be repeated here.

In this embodiment, semi-persistent scheduling can be configured on any carrier, so the UE can determine whether the current state of the carrier that needs semi-persistent scheduling is activated or deactivated several frames in advance, and if it is in the deactivated state, perform Activate processing. In this embodiment, the carrier can be flexibly activated according to the time of semi-persistent scheduling, instead of keeping the carrier in an activated state waiting to receive semi-persistent scheduling data, thereby shortening the activation time of the carrier and reducing the power consumption of the UE.
