Description

MCCH modification notification and method and device for sending configuration information of modification notification

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for sending MCCH modification notification in a relay network, and a method and device for sending configuration information for MCCH modification notification in a relay network.

Background technique

In the 3GPP LTE Release9 version (that is, the Release9 version of the long-term evolution system of the Third Generation Partnership Project), the enhanced multimedia broadcast multicast service (eMBMS or LTE MBMS) can be broadcast in a multi-cell manner, the so-called single frequency network multicast broadcast (Multicast/Broadcast over Single Frequency Network, MBSFN) transmission, the same data will be transmitted in multiple cells using the same modulation and coding method and on the same physical resources at the same time, and the signals received by different cells can be combined.

MCCH (MBMS Control Channel) is a point-to-multipoint downlink channel in the LTE MBMS system. It is used to transmit control information from the network side to the user equipment (UE). This channel is only for user terminals receiving LTE MBMS services. it works. The network side indicates the location information of the MCCH in a broadcast control channel (Broadcast Control Channel, BCCH), so that the user terminal can read the information transmitted on the MCCH according to the indicated location.

The information transmitted on the MCCH includes: LTE MBMS service information and information related to radio resource allocation, where:

MBMS service information: indicates the available MBMS services in the cell. For each business, information such as business identification (service ID), session identification (session ID) may be included;

Information related to radio resource allocation: One or more MBMS services describe the radio resource information used in the served cell. For each service, it may include the physical channel information occupied by the service, transmission channel information, etc., and other information.

When the information carried by the MCCH changes, such as when the MBMS service changes, the session or radio bearer information changes, the network side needs to notify the user terminal; that is, the network side needs to send the MCCH modification notification to the user terminal; After the MCCH modification notification, it will listen to the MCCH to obtain new information after the change.

In LTE Release 10, a relay node (Relay Node, RN) will be introduced into the network as an important means to expand system coverage and improve system capacity. As shown in FIG. 1 , the RN is similar to a base station in the Release10 network, and has its own independent physical cell ID (Physical Cell id).

How to eliminate the impact of RN introduction on UE receiving MBMS service in the network where RN is introduced, and how to receive MCCH modification notification in time are problems that need to be solved urgently, but there is no corresponding solution at present.

Detailed ways

After the RN is introduced into the LTE system, there are the following requirements for MBMS-related notification signaling transmission:

For the situation that RN supports MBMS transmission, RN should timely notify UE of the MCCH modification notification information related to MBMS transmission, so that UE can receive the update content of MCCH in time, so as to ensure that UE can receive information related to MBMS service;

In the case that the RN does not support MBMS transmission, it is still necessary to use the characteristics of the MBSFN transmission network so that the UE can receive the transmission information of the MBMS service of other cells. Therefore, it is necessary to formulate a signaling transmission mechanism so that the UE can know the change of the MCCH on the network side in time notify.

In order to meet the requirements for sending MCCH modification notification information in the above relay network, the embodiment of the present invention provides a corresponding solution, wherein:

For the case where RN supports MBMS transmission, the embodiment of the present invention obtains MCCH modification notification sending configuration information and MCCH modification notification information from DeNB before the specified sending time of sending MCCH modification notification information by RN, and configures MCCH modification notification sending configuration The information is notified to the UE, and when the sending time of the MCCH modification notification information arrives, the RN and the DeNB adopt the MBSFN method to synchronously send the MCCH modification notification information. Wherein the MCCH modification notification transmission configuration information includes: the sending location information corresponding to the MCCH modification notification information, and the relevant parameters include: the number of repetitions for sending the MCCH modification notification, the offset of the sending notification information, and the specific sending notification information subframe. The specific implementation of this solution will be described in detail below through Embodiment 1.

For the situation that RN does not support MBMS transmission, in the embodiment of the present invention, RN obtains MCCH modification notification information from DeNB before the next MCCH modification boundary, and then sends the obtained MCCH modification notification information to UE through downlink control signaling. The specific implementation of the solution will be described in detail below through Embodiment 2 and Embodiment 3.

The MCCH modification notification transmission configuration information described in the embodiments of the present invention is mainly used to indicate the specific sending location of the MCCH modification notification information, and may also include at least the number of times that the UE has failed to receive the MCCH modification notification information. It is used to instruct the UE to read the updated MCCH content at the next MCCH modification boundary, including MBMS service information, radio resource allocation and other related information; the MCCH modification notification information can be used to indicate to the UE which MBSFN area the corresponding MCCH has changed.

The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one

The network architecture involved in this embodiment may be shown in FIG. 1 , including a master base station (DeNB) and an RN, where the RN supports MBMS transmission. For this situation, in this embodiment, the RN may receive the MCCH modification notification sending configuration information and the MCCH modification notification information from the DeNB in advance, and may send the MCCH modification notification sending configuration information to the UE. When the sending time of the MCCH modification notification information stipulated by DeNB arrives, the RN and the base station will send the MCCH modification notification information synchronously, so as to ensure that the UE can read the updated MCCH content at the next MCCH modification boundary according to the MCCH modification notification information, including MBMS services Information such as information and radio resource allocation related information, in order to correctly receive MBMS services.

As shown in Figure 2, the process of the embodiment of the present invention may include:

Step 201, RN receives MCCH modification notification sending configuration information from DeNB.

In this step, the DeNB can send downlink control information according to the system agreement, which carries the MCCH modification notification transmission configuration information, so that the RN can obtain the MCCH modification notification transmission configuration information by monitoring and receiving the downlink control information. Wherein, the time for the DeNB to send the configuration information and for the RN to receive the configuration information may be specified by the system or stipulated by the specification. The transmission time of the MCCH modification notification transmission configuration information formulated by the system or the specification should be able to ensure that the RN or UE receives the MCCH modification notification transmission configuration information before receiving the MCCH modification notification information.

Step 202, the RN sends the MCCH modification notification sending configuration information to the UE.

In this step, the RN may carry the MCCH modification notification sending configuration information in the downlink control signaling and send it to the UE. The downlink control signaling may be PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) signaling, or MAC (Media Access Control, Media Access Control) layer signaling, or RRC (Radio Resource Control, radio resource control ) layer signaling, or other control signaling capable of carrying MCCH modification notification information.

Step 203, the RN receives MCCH modification notification information from the DeNB.

In this step, the time for the RN to receive the MCCH modification notification information may be specified by the system or stipulated by the specification.

Step 204, the RN sends the MCCH modification notification information at the sending time of the MCCH modification notification information specified by the DeNB.

Since the RN sends the MCCH modification notification information at the sending time of the MCCH modification notification information specified by the DeNB, at this time, the DeNB also sends the MCCH modification notification information, and there is a mechanism to ensure that the RN or UE can receive the MCCH modification notification information before the MCCH modification boundary arrives. Therefore, the RN and the DeNB will synchronously send the MCCH modification notification information, which can ensure that the UE receives the notification information sent by the RN before the MCCH modification boundary arrives.

When the UE receives the MCCH modification notification information according to the received MCCH modification notification transmission configuration information, it reads the updated MCCH content at the next MCCH modification boundary, including the modified eMBMS service information and radio resource allocation related information, etc., so that The MBMS service can be received according to the modified eMBMS service information and radio resource allocation related information.

In the above process, in the timing of sending the MCCH modification notification sending configuration information and MCCH modification notification information, generally speaking, because the MCCH modification notification sending configuration information is semi-static information, and the MCCH modification notification information may change every cycle, so The MCCH modification notification is sent first to send the configuration information, and then the MCCH modification notification information is sent.

In the above process, since the RN supports MBMS transmission, the RN can receive the MCCH modification notification information sent by the base station through the downlink control signaling of the base station, and send it to the UE. Specifically, the DeNB may carry the MCCH modification notification information in downlink control signaling (such as PDCCH signaling) and send it to the RN, and the RN may also carry the MCCH modification notification information in the RN's downlink control signaling to the UE (such as PDCCH signaling) sent to the UE.

Based on the same technical concept, the embodiment of the present invention also provides an RN device.

As shown in FIG. 3, the RN device may include: a second receiving module 301, a second sending module 302, a first receiving module 303, and a first sending module 304, wherein:

The second receiving module 301 is configured to receive MCCH modification notification transmission configuration information from the base station; this module can receive the MCCH modification notification transmission configuration information carried in it by receiving the downlink control signaling sent by the base station;

The second sending module 302 is configured to send the MCCH modification notification sending configuration information received by the second receiving module 301 to the user equipment; this module can send the MCCH modification notification sending configuration information through a downlink control signal;

The first receiving module 303 is configured to receive MCCH modification notification information from the base station;

The first sending module 304 is configured to send the MCCH modification notification sending configuration information received by the first receiving module 303 to the user equipment. The module may send the MCCH modification notification information at the same time as the base station sends the MCCH modification notification information, that is, send the MCCH modification notification information synchronously with the base station.

The second receiving module 301 can receive the MCCH modification notification sending configuration information from the base station according to the time specified by the system or specified by the specification; the first receiving module 303 can receive the MCCH from the base station according to the time specified by the system or specified by the specification Modify notification information.

When the first receiving module 303 receives the MCCH modification notification information, it can receive the MCCH modification notification information by receiving the downlink control signaling that carries the MCCH modification notification information sent by the base station; the first sending module 304 can send the MCCH modification notification information The MCCH modification notification information is carried in the PDCCH signaling and sent to the user equipment.

It can be seen from the above description that for the case where the RN supports MBMS transmission, the RN obtains the MCCH modification notification information and the notification sending configuration information before the specified MCCH modification notification information sending time, and sends the notification sending configuration information to the UE. In this way, When the sending time of the MCCH modification notification information specified by the DeNB arrives, the RN and the DeNB use the MBSFN transmission method to send the MCCH modification notification information synchronously, so that the UE can read the updated MCCH at the next MCCH modification boundary according to the MCCH modification notification information Content, including MBMS service information and information related to radio resource allocation. It can be seen that according to the above description, the RN can send the MCCH modification notification information related to MBMS transmission to the UE in time, so that the UE can receive the updated content of the MCCH in time, thereby ensuring that the UE can receive the information related to the MBMS service.

Embodiment two

The network architecture involved in this embodiment may be shown in FIG. 1 , including a master base station (DeNB) and an RN, where the RN does not support MBMS transmission. For this situation, in this embodiment, the RN can receive the MCCH repair notification information from the DeNB before the MCCH modification boundary and send it to the UE before the MCCH modification boundary, so as to ensure that the UE can receive the MCCH modification notification information in time, so that Read updated MCCH content at the next MCCH modification boundary, including MBMS service information and radio resource allocation related information.

As shown in Figure 4, the process of the embodiment of the present invention may include:

Step 401, RN receives MCCH modification notification information from DeNB. Optionally, the RN may return confirmation information to the DeNB after receiving the MCCH modification notification information.

In this step, the DeNB may carry the MCCH modification notification information in the downlink control signal and send it to the RN. The downlink control signaling can be dedicated control signaling or common control signaling, and the way the signaling can be carried can be PDCCH signaling, MAC layer signaling, RRC layer signaling, or other methods that can carry MCCH Modify the control signaling of the notification information.

Step 402, before the MCCH modification boundary (that is, before the end of the current MCCH modification cycle, that is, before the start of the next MCCH modification cycle), the RN sends the MCCH modification notification information received from the DeNB to the UE, so that the UE does not have to The notification information is received at the sending time of the MCCH modification notification information specified by the DeNB.

In this step, the RN may carry the MCCH modification notification information in the downlink control signal and send it to the UE. The downlink control signaling can be dedicated control signaling or common control signaling, and the way the signal can be carried can be PDCCH signaling, MAC layer signaling, RRC layer signaling, or other methods that can carry MCCH Modify the control signaling of the notification information.

After receiving the MCCH modification notification information, the UE reads the updated MCCH content at the subsequent MCCH modification boundary, that is, at the next MCCH modification boundary, including MBMS service information and radio resource allocation related information, so that it can eMBMS service information and radio bearer related information to receive MBMS services.

Normally, MCCH information is sent periodically in the same MCCH modification cycle with the repetition period, and is sent repeatedly with the same content. For example, the MCCH modification notification is sent twice within one 512ms, and the updated MCCH modification is sent within the subsequent 512ms In this case, it can also be considered that the beginning of the cycle of sending updated MCCH modification notification information is the MCCH modification boundary, or in other words, when the cycle of sending MCCH modification notification information different from the previous content begins The moment is the modification boundary of the MCCH.

In the above process, since the RN does not support MBMS transmission, according to the existing protocol, the RN cannot receive the MCCH modification notification information from the DeNB through the MBSFN subframe and send it to the UE. Therefore, in this embodiment, the DeNB can carry the MCCH modification notification information in the downlink The control signaling (which may be public control signaling or dedicated control signaling) is sent to the RN, and the RN may also carry the MCCH modification notification information in the downlink control signaling (which may be public control signaling or dedicated control signaling) and send it to the UE.

Similar to the embodiment, the time for the DeNB to send the MCCH modification notification to send the configuration information can be specified by the system or stipulated by the specification, and it should be ensured that the RN or UE can receive it before the corresponding MCCH modification boundary (considering factors such as appropriate transmission delays) ), therefore, after the RN receives relevant information from the DeNB and sends it to the UE, it can ensure that the UE can receive it before the corresponding MCCH modification boundary.

Based on the same technical concept, the embodiment of the present invention also provides an RN device.

As shown in FIG. 5, the RN device may include: a first receiving module 501 and a first sending module 502, wherein:

The first receiving module 501 is configured to receive MCCH modification notification information from the base station; this module can receive the MCCH modification notification information carried therein by receiving the downlink control signaling sent by the base station;

The first sending module 502 is configured to send the MCCH modification notification information received by the first receiving module 501 to the user equipment. The module may send the MCCH modification notification information received from the base station to the user equipment before the modification boundary corresponding to the MCCH modification notification information, and the module may send the MCCH modification notification information through downlink control signaling.

It can be seen from the above description that for the situation that the RN does not support MBMS transmission, the RN obtains the MCCH modification notification information before the MCCH modification boundary, and sends it to the UE through downlink control signaling before the MCCH modification boundary, so that the UE According to the MCCH modification notification information, the updated MCCH content, including MBMS service information and radio bearer related information, can be read in time at the next MCCH modification boundary. It can be seen that according to the above description, the RN can send the MCCH modification notification information related to MBMS transmission to the UE in time, so that the UE can receive the updated content of the MCCH in time, thereby ensuring that the UE can receive the information related to the MBMS service.

Embodiment Three

The network architecture involved in this embodiment may be shown in FIG. 1 , including a master base station (DeNB) and an RN, where the RN does not support MBMS transmission. For this situation, in this embodiment, the RN can monitor the MCCH modification notification information sent by the DeNB when the DeNB sends the MCCH repair notification information, and send the detected MCCH modification notification information to the UE, so as to ensure that the UE can receive the MCCH in time Modify the notification information, so as to read the updated MCCH content at the next MCCH modification boundary according to the modification notification information, including information such as MBMS service information and radio resource allocation related information, so as to correctly receive the MBMS service.

As shown in Figure 6, the process of the embodiment of the present invention may include:

Step 601, RN receives MCCH modification notification sending configuration information from DeNB. Wherein, the MCCH modification notification transmission configuration information may be carried in the downlink control signaling.

Step 602 , when the DeNB sends the MCCH modification notification information, the RN monitors the MCCH modification notification information sent by the DeNB at a corresponding location according to the received MCCH modification notification sending configuration information. Optionally, the RN may return confirmation information to the DeNB after receiving the MCCH modification notification information.

Step 603: After listening to the MCCH modification notification information, the RN sends the MCCH modification notification information received from the DeNB to the UE before the next MCCH modification boundary, so that the UE does not need to send the MCCH modification notification information specified by the DeNB Time to receive the notification information.

In this step, if the MBMS service information and radio resource allocation-related information have not changed, the DeNB may not send the MCCH modification notification information when sending the MCCH modification notification information, so that the RN cannot monitor the MCCH modification notification information, and will not sent to the UE.

In this step, the RN may carry the MCCH modification notification information in public or dedicated control signaling and send it to the UE. The control signaling may be PDCCH signaling, MAC layer signaling, RRC layer signaling, or other control signaling capable of carrying MCCH modification notification information.

After receiving the MCCH modification notification information, the UE reads the updated MCCH content at the subsequent MCCH modification boundary, that is, at the next MCCH modification boundary, including MBMS service information and radio resource allocation related information, so that it can eMBMS service information and radio bearer related information to receive MBMS services.

In the above process, the time for the RN to receive the MCCH modification notification information can be specified by the system, or specified by the specification. Preferably, the time is the time when the DeNB sends the MCCH modification notification information, or other system-specified sending time. Wherein, the time for the DeNB to send the MCCH modification notification information should be between the corresponding MCCH modification boundaries.

In the above procedure, the RN may carry the MCCH modification notification information in public or dedicated control signaling and send it to the UE.

Based on the same technical concept, the embodiment of the present invention also provides an RN device.

As shown in FIG. 7, the RN device may include a first receiving module 701 and a first sending module 702, where:

The first receiving module 701 is configured to receive MCCH modification notification information from the base station;

The first sending module 702 is configured to send the MCCH modification notification information received by the first receiving module 701 to the user equipment. The module may send the MCCH modification notification information before the MCCH modification boundary, and may send the MCCH modification notification information through downlink control signaling when sending the information.

The device may also include a third receiving module 703, configured to receive MCCH modification notification transmission configuration information from the base station, so that the first receiving module 701 can receive MCCH modification notification information at a corresponding location according to the configuration information.

It can be seen from the above description that for the case where the RN does not support MBMS transmission, the RN sends the MCCH modification notification information received when the DeNB sends the MCCH modification notification information to the UE before the MCCH modification boundary, so that the UE can Modify the notification information, and read the updated MCCH content in time at the next MCCH modification boundary, including MBMS service information and radio bearer related information. It can be seen that according to the above description, the RN can send the MCCH modification notification information related to MBMS transmission to the UE in time, so that the UE can receive the updated content of the MCCH in time, thereby ensuring that the UE can receive the information related to the MBMS service.

Embodiment Four

In this embodiment, the RN can send the MCCH modification notification transmission configuration information received from the DeNB to the UE. On the one hand, the UE fails to receive the MCCH modification notification transmission configuration information sent by a cell other than the cell where the RN is located. In the case of the RN, the modified MCCH content can be read according to the configuration information sent by the MCCH modification notification sent by the RN, including MBMS service information and radio resource allocation related information, so as to ensure that the user equipment can receive the MBMS service related information.

As shown in Figure 8, the process of this embodiment may include:

Step 801, the RN receives the MCCH modification notification sent by the DeNB to send configuration information.

In this step, the DeNB may carry the MCCH modification notification transmission configuration information in the downlink control signaling, and the RN may receive the MCCH modification notification transmission configuration information carried in the downlink control signaling sent by the DeNB.

Step 802, the RN sends the received MCCH modification notification sending configuration information to the UE.

In this step, the RN may carry the MCCH modification notification sending configuration information in the downlink control signaling and send it to the UE.

The downlink control signaling in the above process may be dedicated control signaling, such as PDCCH signaling, or MAC layer signaling, or RRC layer signaling; it may also be common control signaling.

Based on the same technical idea as this embodiment, this embodiment of the present invention also provides a relay node device.

As shown in FIG. 9, the relay node device may include: a receiving module 901 and a sending module 902, wherein:

The receiving module 901 is configured to receive the MCCH modification notification transmission configuration information sent by the base station; this module can receive the MCCH modification notification transmission configuration information carried in it by receiving the downlink control sent by the base station;

The sending module 902 is configured to send the MCCH modification notification sending configuration information received by the receiving module 901 to the user equipment. The module may carry the MCCH modification notification sending configuration information in downlink control signaling sending.

The present invention also proposes another embodiment in which RN does not support MBMS service transmission, that is, the base station only transmits MCCH modification notification sending configuration information to RN, and RN does not need to send it to UE, as shown in the figure. In this way, the RN does not need to notify the UE through signaling, which reduces the overhead of the interface (Uu interface) between the RN and the UE. But this may introduce interference. In this embodiment, in order to eliminate the interference (to the UE receiving the MBMS service) that may be introduced in the MBSFN subframe transmitting the MBMS service, the RN may send configuration information to the corresponding MBSFN subframe (that is, the MCCH modification notification) The indicated transmission position of the MCCH modification notification information) the OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) symbol for transmitting data information is set to mute (Mute), that is, no user is scheduled, so no user data information is transmitted ; You can also choose to send or not send any pilot information. In this way, although the UE does not know that these subframes are MBSFN subframes, it will receive services as regular unicast subframes, but due to the above-mentioned processing operations taken by the RN, the UE will not receive its own scheduling information and user data. Therefore, the introduced interference and the impact on the UE can be reduced to a certain extent.

Based on the same technical concept as the above process, the embodiment of the present invention also provides an RN device, including: a first receiving module, and may further include a setting module, wherein:

The first receiving module is used to receive MCCH modification notification sending configuration information from the base station;

A setting module, configured to send the MCCH modification notification information indicated by the MCCH modification notification sending configuration information received by the first receiving module. Frequency division multiplexing OFDM symbols are set to silence.

It should be noted that the downlink control signaling described in the foregoing embodiments of the present invention may be dedicated control signaling or common control signaling.

It should also be noted that, in the above-mentioned embodiments of the present invention, if the MBMS service information and radio resource allocation related information have not changed, the DeNB may not send the MCCH modification notification information when the specified MCCH modification notification information occurs, so that the RN monitors If there is no MCCH modification notification information, it will not be sent to the UE.

Through the description of the above embodiments, those skilled in the art can clearly understand that the present invention can be implemented by means of software plus a necessary general-purpose hardware platform, and of course it can also be implemented by hardware, but the former is a better implementation under a lot of information Way.
