Technical Field

Background

Next Generation (NG) communication systems can support shorter delays, greater bandwidths, and support a large number of connections. In the next generation communication system, a dual connectivity (dual connectivity, DC) technology is used to enable the ue to obtain transmission resources from a Master Node (MN) and a Secondary Node (SN) located at the network side at the same time, thereby improving the radio resource utilization and the transmission rate. In the DC state, the terminal simultaneously listens to and transmits data over both air links of the primary cell group (master cell group, MCG) and the secondary cell group (secondary cell group, SCG).

After the SCG is set to a deactivated or suspended state, the user equipment cannot send and receive data through the SCG, and when uplink data arrives, the user terminal can request to activate the SCG from the network side. How the user terminal requests activation of SCG becomes a problem to be solved.

Referring to fig. 1, fig. 1 is a schematic diagram of a communication network architecture according to an embodiment of the present application. As shown in fig. 1, the user equipment 130 supports Multi-Radio dual connectivity (Multi-RadioDual Connectivity, MR-DC), and the access network device 110 and the access network device 120 together provide a data transmission service for the user equipment 130, where the access network device 110 is a Master Node (MN), and the access network device 120 is a Secondary Node (SN). In dual connectivity (MR-DC, hereinafter the same) the data radio bearers (Data Radio Bearer, DRB) may be served by the MN or SN independently or by both the MN and SN. The data radio bearer is called MCG data when served by MN only, i.e. the radio link control layer protocol (Radio Link Control, RLC) bearer corresponding to DRB is located only in MCG; the service is called SCG data radio bearer when only being served by SN, namely the RLC bearer corresponding to DRB is only located in SCG; meanwhile, the RLC bearer corresponding to the DRB is located in the MCG and the SCG. In addition, the locations of the packet data convergence protocol (packet data convergence protocol, PDCP) entities according to the DRBs can be classified into MN terminated DRB and SN terminated DRB.

Wherein a control plane connection (denoted S1-C in fig. 1) exists between the access Network device 110 and a Core Network (CN) 140. In SCG data radio bearer mode, if PDCP of DRB is located at SN, there is a user plane connection (denoted by S1-U in fig. 1) between access network device 120 and CN140, and downlink data of DRB is sent by CN140 to access network device 120. In the MN terminated split data radio bearer mode, only user plane data exists between the access network device 110 and the CN140, all downlink data is first transmitted to the access network device 110, then sent to the access network device 120 through the access network device 110 part, and finally data is simultaneously sent to the user device 130 on the access network device 110 and the access network device 120. For uplink data, the uplink data may be transmitted via access network device 110 or access network device 120. The above access network device 110 may also be referred to as a primary base station or primary access network device, and the access network device 120 may also be referred to as a secondary base station or secondary access network device.

In this application, user device 130 may be any type of device that provides voice and/or data connectivity to a user, such as a handheld device having wireless connectivity, or a processing device connected to a wireless modem. For example, mobile telephones (or "cellular" telephones) computers with mobile terminals, portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices, smart wearable devices, and the like may be included. Such as personal communication services (personal communication service, PCS) phones, cordless phones, session initiation protocol (session initiation protocol, SIP) phones, wireless local loop (wireless local loop, WLL) stations, personal digital assistants (personal digital assistant, PDAs), smart bracelets, smart watches, and the like. But also limited devices such as devices with lower power consumption, or devices with limited memory capabilities, or devices with limited computing capabilities, etc. Examples include bar codes, radio frequency identification (radio frequency identification, RFID), sensors, global positioning systems (global positioning system, GPS), laser scanners, and other information sensing devices. The user equipment may communicate with the CN140 via an access network, such as a radio access network (radio access network, RAN), to exchange voice and/or data with the RAN. Furthermore, the chip applied in the above-described device may also be referred to as a user device.

For example, the base station device in the LTE system, that is, evolved NodeB (eNB/eNodeB), and the access network side device in the NR system, including the gNB, transmission point (TRP), and the like may be mentioned. Furthermore, when an eNB accesses a 5G core network (5th Generation Core Network,5GC), the LTE eNB may also be referred to as an LTE eNB. Specifically, the eLTE eNB is an evolved LTE base station device based on the LTE eNB, and can be directly connected with the 5G CN, and the eLTE eNB also belongs to the base station device in the NG-RAN. Access network device 110 or access network device 120 may also be a wireless endpoint (wireless terminal, WT), such as an Access Point (AP) or an access controller (access controller, AC), or other device having communication capabilities with the terminal and the core network, such as a relay device, a vehicle device, a smart wearable device, etc., and the type of device is not limited in this embodiment of the present application.

In this application, the devices corresponding to the access network device 110, the access network device 120, and the CN140 may be collectively referred to as a network device. After the SCG is set to the deactivated or suspended state, for the SCG data radio bearer, the user equipment 130 may send an activate SCG request to the network device according to the uplink data transmission state to request activation of the SCG from the network device. For the split data radio bearer, the network device may configure whether the user device requests to activate SCG for the split data radio bearer, and if the network device configures the user device 130 to activate SCG for the split data radio bearer, the user device 130 may send an SCG activation request to the network device according to the uplink data transmission status to request to activate SCG; if the network device configures the ue 130 to be unable to activate SCG for the split data radio bearer request, the ue 130 submits PDCP PDUs to the RLC entity on the MN side.

Referring to fig. 2, fig. 2 is a flowchart of a method for activating SCG according to an embodiment of the present application. In fig. 2, the method for activating SCG provided in the embodiment of the present application may include the following steps S201 to S203.

S201, the user equipment acquires an uplink data transmission state of a first data radio bearer associated with the SCG.

In some possible embodiments, when the user equipment transmits uplink data to the network equipment through the first data radio bearer, the user equipment may acquire an uplink data transmission status of the first data radio bearer associated with the SCG. The first data radio bearer associated with the SCG may be a split data radio bearer or an SCG data radio bearer, which may be specifically determined according to an actual application scenario, and is not limited herein.

The uplink data transmission state of the first data radio bearer may include an uplink buffer data amount of the first data radio bearer, a data amount of the first uplink data, a transmission event state of the first data radio bearer, and the like. The first uplink data is determined for the ue, and the uplink data is sent to the network device through the first data radio bearer. The data amount of the uplink buffer data is the data amount of the buffered uplink data in the first data radio bearer at the current time, and the data amount of the first uplink data is the data amount of uplink data sent to the network device through the first data radio bearer, that is, the data amount of the uplink data expected to be sent by the first data radio bearer at the current time. The transmission event status is a plurality of event statuses for determining whether a buffer status report (Buffer Status Report, BSR) trigger condition is satisfied to request an uplink data transmission resource from a network device.

S202, the user equipment sends an SCG activation request to the network equipment according to the uplink data transmission state of the first data radio bearer.

In some possible embodiments, the user equipment may send an SCG activation request to the network device to request the network device to activate SCG when the uplink data transmission status of the first data radio bearer satisfies the activation request trigger condition. In this application, a specific uplink data transmission state may correspond to one or more activation request triggering conditions.

In some possible embodiments, when the uplink data transmission state includes an uplink buffer data amount of the first data radio bearer, referring to fig. 3, fig. 3 is a schematic flow chart of sending an SCG activation request according to the uplink buffer data amount provided in the embodiment of the present application, which may specifically include the following steps S301 to S302.

S301, the user equipment determines the uplink buffer data volume of the first data radio bearer.

In some possible embodiments, the amount of uplink buffered data of the first data radio bearer is the amount of uplink data buffered in the first data radio bearer.

S302, the user equipment sends an SCG activation request when the uplink buffer data volume is larger than a preset uplink buffer data volume threshold.

In some possible embodiments, the user equipment may determine whether the amount of uplink buffered data of the first data radio bearer exceeds an uplink buffered data amount threshold of the first data radio bearer. When the user equipment determines that the uplink buffer data amount of the first data radio bearer exceeds the uplink buffer data amount threshold of the first data radio bearer, the user equipment may send an SCG activation request to the network equipment. That is, in the case where the first data radio bearer has configured an uplink buffer data amount threshold, the user equipment may send an SCG activation request to the network equipment once the uplink buffer data amount of the first data radio bearer exceeds the threshold.

The first data radio bearer may be an SCG data radio bearer or a split data radio bearer.

Wherein the uplink buffer data amount threshold of the first data radio bearer is configurable by the network device through radio resource control (Radio Resource Control, RRC) signaling. For example, the network device may configure the uplink buffer data amount threshold of the first data radio bearer together when the first data radio bearer is established, or may configure the uplink buffer data amount threshold of the first data radio bearer through an RRC connection reconfiguration procedure. For example, when the network device needs to initiate a configuration operation for the first data radio bearer, uplink buffer data amount threshold configuration information may be sent to the user device over the signaling radio bearer (signalling radio bearers, SRB) 1 over the DL DCCH. The user equipment sends an acknowledgement message on SRB1 over the UL DCCH, thereby completing RRC connection reconfiguration and configuration of the uplink buffer data amount threshold of the first data radio bearer.

In some possible embodiments, the SCG activation request sent by the user equipment to the network equipment may carry the bearer identifier of the first data radio bearer and the uplink buffer data amount of the first data radio bearer, so as to inform the network equipment that the uplink buffer data amount of the first data radio bearer corresponding to the bearer identifier exceeds the uplink buffer data amount threshold, thereby enabling the network equipment to activate the SCG associated with the first data radio bearer.

In some possible embodiments, when the uplink data transmission state includes the data amount of the first uplink data, referring to fig. 4, fig. 4 is a schematic flow chart of sending the SCG activation request according to the data amount of the uplink data provided in the embodiment of the present application, and the steps S401 to S402 may be specifically included.

S401, the user equipment determines the data quantity of the first uplink data.

In some possible embodiments, the first uplink data determines, for the ue, uplink data to be sent to the network device through the first data radio bearer, that is, the first uplink data is uplink data to be buffered by the ue to the first data radio bearer (an amount of uplink data that the first data radio bearer expects to send) for sending to the network device.

S402, the user equipment sends an SCG activation request when the data quantity of the first uplink data is larger than a preset uplink data quantity threshold.

In some possible embodiments, the user equipment may determine whether the data amount of the first uplink data of the first data radio bearer exceeds an uplink data amount threshold of the first data radio bearer. When the user equipment determines that the data amount of the first uplink data of the first data radio bearer exceeds the uplink data amount threshold of the first data radio bearer, the user equipment may send an SCG activation request to the network equipment. That is, in the case that the first data radio bearer has been configured with an uplink data amount threshold, the user equipment may send an SCG activation request to the network equipment once the data amount of the first uplink data of the first data radio bearer exceeds the threshold.

The uplink data amount threshold of the first data radio bearer may be configured by the network device through RRC signaling. For example, the network device may configure the uplink data volume threshold of the first data radio bearer at the same time when the first data radio bearer is established, and may also configure the uplink data volume threshold of the first data radio bearer through an RRC connection reconfiguration procedure. For example, when the network device needs to initiate a configuration operation for the first data radio bearer, uplink data amount threshold configuration information may be sent to the user device on SRB1 over the DL DCCH. The user equipment sends an acknowledgement message on SRB1 over the UL DCCH to complete RRC connection reconfiguration and configuration of the uplink data amount threshold of the first data radio bearer.

In some possible embodiments, the SCG activation request sent by the user equipment to the network equipment may carry the bearer identifier of the first data radio bearer and the data amount of the first uplink data of the first data radio bearer, so as to inform the network equipment that the uplink data amount of the first uplink data of the first data radio bearer corresponding to the bearer identifier exceeds the uplink data amount threshold, thereby enabling the network equipment to activate the SCG associated with the first data radio bearer.

In some possible embodiments, when the uplink data transmission state includes an uplink buffer data amount of the first data radio bearer and the first data radio bearer is a split data radio bearer, referring to fig. 5, fig. 5 is another flow chart of sending an SCG activation request according to the uplink buffer data amount provided in the embodiment of the present application, which may specifically include the following steps S501 to S502.

S501, the user equipment determines the uplink buffer data volume of the first data radio bearer.

S502, the user equipment sends an SCG activation request when the uplink buffer data amount is larger than a preset uplink data separation threshold value.

In some possible embodiments, the user equipment may determine whether an amount of uplink buffered data of the first data radio bearer exceeds an uplink data separation threshold of the DRB. The threshold is configured by the network device via RRC dedicated signaling to determine whether uplink data is sent only to the primary path or to both the MCG and SCG. Since the current SCG is in a deactivated or suspended state, when the ue determines that the amount of uplink buffer data of the first data radio bearer exceeds an uplink data separation threshold preset by the ue, it indicates that the ue needs to send part of the data of the first data radio bearer to the network device through the SCG, that is, needs to take part of the load of the uplink data sent to the network through the SN. At this time, the user equipment may transmit an SCG activation request to the network equipment to transmit a part of the uplink data to the network equipment through the SCG.

Wherein the first data radio bearer is a split data radio bearer. The uplink data separation threshold may be configured by the network device through RRC signaling.

In some possible embodiments, the SCG activation request sent by the user equipment to the network equipment may carry the bearer identifier of the first data radio bearer and the uplink buffer data amount of the first data radio bearer, so as to inform the network equipment that the uplink buffer data amount of the first data radio bearer corresponding to the bearer identifier exceeds the uplink data separation threshold of the user equipment, thereby enabling the network equipment to activate the SCG associated with the first data radio bearer.

In some possible embodiments, when the current uplink buffer data amount of the split data radio bearer exceeds the uplink data separation threshold of the user equipment, the BSR may also be triggered for the split data radio bearer, and the procedure of reporting the BSR to the MN is regarded as a procedure of sending the SCG activation request to the network equipment.

In some possible embodiments, when the uplink data transmission state includes a transmission event state of the first data radio bearer, and the first data radio bearer is an SCG data radio bearer, referring to fig. 6, fig. 6 is a schematic flow chart of sending an SCG activation request according to the transmission event state provided in the embodiment of the present application, which may specifically include the following step S601.

S601, the user equipment sends an SCG activation request when a transmission event state meets a preset buffer status report triggering condition.

In some possible embodiments, since the SCG is in a deactivated or suspended state at the current time, when the ue needs to send uplink data to the network device through the SCG, it may be determined whether a buffer status report triggering condition for triggering the BSR for the SCG data radio bearer is satisfied according to a transmission event state of the first data radio bearer, that is, a transmission event state of the ue for the SN side.

Optionally, the ue determines that when all logical channels of all logical channel groups (Logical Channel Group, LCG) of the SCG have no uplink data that can be sent, and when there is uplink data on a logical channel belonging to any LCG, the ue triggers a buffer status report for the SCG. If the ue first sends uplink data to the network device, the ue may trigger a buffer status report for the SCG data radio bearer to send an SCG activation request to the network device.

Optionally, if the ue has sent an SCGBSR, at this time, a certain SCG DRB of the ue has uplink data arrived, and the priority of the logical channel is higher than that of any logical channel that has already been reported to the SCGBSR, at this time, the ue triggers a BSR for the SCG data radio bearer to send an SCG activation request to the network device.

Optionally, since the ue periodically updates the data buffer status of the SCG data radio bearer to the network device, and on the other hand, the network device configures a Timer for the SCG MAC of the ue through the IE, i.e., the periodic cbsr-Timer field of the MAC-MainConfig, if the Timer times out, the ue triggers the BSR for the SCG data radio bearer. For example: when the ue needs to upload a large file through the SCG data radio bearer, the ue triggers the BSR and receives the UL grant, and simultaneously buffers data in the SCG data radio bearer, so that the ue needs to continuously update the amount of uplink data that needs to be transmitted through the SCG data radio bearer. So that the user equipment triggers BSR for the SCG data radio bearer in the above state.

Optionally, when the ue has not received the UL grant after triggering the BSR for the SCG data radio bearer, since the network device configures a Timer for the ue through the IE: the retbsr-Timer field of MAC-MainConfig, when the Timer times out and any one logical channel of any one LCG of the SCG MAC of the ue has data to send, i.e. the ue needs to send uplink data, the SCGBSR will be triggered to send an SCG activation request to the network device.

Wherein, since the SCG is in a deactivated or suspended state at the present moment, the process that the user equipment triggers the BSR for the SCG data radio bearer is regarded as a process of sending the SCG activation request to the network equipment.

In some possible embodiments, in the implementation shown in any of the foregoing fig. 3 to 5, the SCG activation request may be sent to the network device in a manner shown in fig. 6 that triggers the BSR and reports the BSR to the network device. For example, when the uplink buffer data amount of the first data radio bearer is greater than a preset buffer data amount threshold, the ue may trigger and report a BSR. When the data amount of the first uplink data of the first data radio bearer is greater than the preset uplink data amount threshold, the user equipment may trigger the BSR and report the BSR, which is not described herein.

Referring to fig. 7, fig. 7 is a schematic flow chart of sending an SCG activation request according to an embodiment of the present application. The transmitting of the SCG activation request shown in fig. 7 may include the following steps S701 to S702.

S701, the user equipment adds a media access control unit corresponding to the buffer status report of the SCG in the media access control protocol data unit.

In some possible implementations, the user equipment reports the BSR by adding a BSR MAC Control Element (CE) in the form of a media access Control (Media Access Control, MAC) protocol data unit (Protocol Data Unit, PDU) sent to the network equipment. The BSR may apply resources to the network device for uplink data upload of the user equipment. After receiving the BSR, the network equipment allocates proper resources for the user equipment according to the content carried by the BSR. To avoid a significant signaling overhead, the user equipment places one or more logical channels into one LCG (Logical ChannelGroup ), reporting one BSR value for each LCG. Instead of reporting one BSR for each logical channel, the user equipment reports BSRs based on the LCG. Each MAC ce corresponds to a MAC sub-header, and the LCID field in each MAC sub-header is used to indicate the type of control element. The type of the corresponding BSR can be determined by the value of the logical channel identification (Logical Channel Identify, LCID) in the MAC CE header. Each type of BSR occupies one LCID (Logical Channel Identify, logical channel identification) value. Wherein, the total length of LCID is 6bits, and 64 available total.

Further, since the SCG is in the deactivated or suspended state at the present time, the ue can only report the BSR to the MN, so that in order to let the MN know that the BSR received by the MN is the BSR of the SCG, but not the BSR of the MCG, the ue can identify the BSR of the SCG by using a new LCID value, so that after the MN receives the BSR MAC CE, the MN can determine that the BSR reported by the ue is the SCG BSR according to the LCID value in the MAC CE, and the purpose is to activate the SCG. For the corresponding BSR of the split data radio bearer, the ue may report the BSR directly to the MN to inform the MN that the data size of the DRB is larger at this time, and the ue needs to transmit the uplink data of the split data radio bearer through the SCG.

S702, the user equipment transmits the media access control protocol data unit added with the media access control unit.

In some possible implementations, the user equipment may send a MAC PDU to the MN that adds the BSR MAC CE.

In some possible embodiments, in the embodiments shown in any of the above figures 3 to 6, the main purpose of the user equipment sending an SCG activation request to the network device is for the network device to activate the SCG from a deactivated or suspended state. The user equipment may thus send an SCG activation request to the network equipment using the implementation shown in fig. 8. Referring to fig. 8, fig. 8 is another flow chart of sending an SCG activation request according to an embodiment of the present application. The sending of the SCG activation request shown in fig. 8 may include the following step S801.

S801, the user equipment sends an uplink scheduling request through a first PUCCH.

In some possible embodiments, since the BSR is encapsulated in the MAC PDU when the user equipment reports the BSR, there is a delay in transmitting to the network equipment through the PUSCH channel, so the network is notified more quickly, or when the user equipment cannot transmit the BSR, the network equipment may be requested to activate the SCG by transmitting a scheduling request (Scheduling Request, SR) to the network equipment. At this time, the SR sent by the ue to the network device may be regarded as an SCG activation request sent by the ue.

The SR resources are dedicated to the user equipment and are allocated by the network equipment (e.g., eNodeB, gNB), so that the SR resources correspond to the user equipment one by one and the network equipment knows the specific correspondence between the user equipment and the SR resources, and therefore the user equipment does not need to specify its own ID when transmitting the SR. That is, the network device can know the corresponding user device requesting to activate the SCG through the location of the SR resource. Wherein, the SR resource is through IE: the sr-PUCCH-ResourceIndex field of SchedulingRequestConfig is configured.

In general, since SRs are transmitted only in Primary cells (PCell) and PSCell (Primary SCG Cell), a user equipment needs to use a new PUCCH resource on the PCell for transmitting SRs of SCGs. In the above case, the user equipment transmits the SR to the MN through the PUCCH, that is, the network equipment is the MN (primary base station) at this time. In order for the MN to distinguish whether the UE-transmitted SR is for MCG or SCG, the UE uses a new PUCCH resource for SR, which is different from the PUCCH resource transmitting the MCG SR, when the PCell transmits the SCG SR.

Alternatively, the SCG cannot send downlink data to the user equipment or upload uplink data of the user equipment when the SCG is in a deactivated or suspended state, but the SN can determine whether the user equipment has uplink data to be transmitted on the SCG by receiving the SR. The user equipment may transmit an SR through a PUCCH through a Primary secondary Cell (Primary SCG Cell). In the above case, the user equipment transmits SR to SN through PUCCH, i.e. when the network equipment is SN (secondary base station)

S203, the network equipment activates the SCG according to the SCG activation request.

In some possible embodiments, after the network device receives the SCG activation request sent by the user device, the request content carried in the SCG activation request may be determined to determine whether the request is a request for requesting activation of the SCG. When the network device determines the bearer identifier of the first data radio bearer and the uplink buffer data amount of the first data radio bearer in the received SCG activation request, the network device may determine that the SCG activation request is sent by the user device when the uplink buffer data amount of the first data radio bearer is greater than a preset uplink buffer data amount threshold, that is, the user device has informed the network device that the SCG corresponding to the first data radio bearer needs to be activated at the current moment. The network device may activate an SCG associated with the first data radio bearer. Wherein the first data radio bearer is an SCG data radio bearer or a split data radio bearer.

In some possible embodiments, when the network device determines, in the received SCG activation request, a data amount of the first uplink data of the first data radio bearer and a bearer identifier of the first data radio bearer, it may determine that the SCG activation request is sent by the network device when the data amount of the first uplink data of the first data radio bearer is greater than a preset uplink data amount threshold, and at this time, the network device may activate the SCG corresponding to the bearer identifier. The first uplink data of the first data radio bearer is determined for the ue, and the first data radio bearer may be an SCG data radio bearer or a split data radio bearer, which may be specifically determined according to an actual application scenario, and is not limited herein.

In some possible embodiments, after receiving the SCG activation request sent by the user equipment, if the SCG activation request carries the uplink buffer data amount of the first data radio bearer and the bearer identifier of the first data radio bearer, the network equipment may determine that the first data radio bearer is a split data radio bearer according to the bearer identifier, and the SCG request is sent by the user equipment when the uplink buffer data amount of the first radio equipment is greater than the uplink data separation threshold. At this time, the network device may activate the SCG corresponding to the split data radio bearer.

In some possible embodiments, when the SCG activation request is a MAC PDU including a BSR MAC CE sent by the user equipment to the network equipment, the network equipment receiving the MAC PDU is the MN. The MN may parse the BSR MAC CE to obtain buffers for each LCG of the MCG. If the MN can judge that the uplink buffer data quantity of the user equipment on a certain split data radio bearer exceeds an uplink data separation threshold of the user equipment. The MN may activate the SCG at this point. Or when the MAC PDU also carries the uplink buffer data amount of the split data radio bearer or the bearer identifier of the split data radio bearer, it may also indicate that the user equipment requests to activate the SCG corresponding to the split data radio bearer at the current moment, and at this time, the MN may activate the corresponding SCG.

In some possible embodiments, when the MN determines, according to the LCID, that the BSR of the SCG is acquired, that the transmission event state of the first data radio bearer at the current moment satisfies the BSR trigger condition, the MN may also activate the SCG.

In some possible embodiments, when the SN receives the SR sent by the ue through the PUCCH of the PSCell, or when the MN receives the SR sent by the ue through the PUCCH corresponding to the SR of the PCell, it is indicated that the SN or the MN informs that there is uplink data to be transmitted through the SCG at the current time, and the SN or the MN may activate the SCG to enable the ue to upload the uplink data.

In the embodiment of the application, the user equipment can determine whether to send the SCG activation request to the network equipment according to the data volume of the uplink data of the data radio bearer or the size of the uplink buffer data volume, and can send the SCG activation request in real time according to the uplink data transmission state of the data radio bearer. Further, the user equipment requests the network equipment to activate the SCG by reporting the BSR or the SR to the network equipment, so that the network equipment can be timely requested to activate the SCG. In addition, the network device activates the SCG when receiving the SCG request sent by the user device, so that the user device can be ensured to send uplink data through the SCG.
