Description

A transmission method of MBS configuration

【Technical field】

The disclosed embodiments of the present invention relate to the field of communication technologies, and more particularly, to a method for transmitting an MBS configuration and a user equipment.

【Background technique】

The transmission modes of LTE Multimedia Broadcast Multicast Service (MBMS) can be divided into SC-PTM (Single Cell Point-To-Multipoint, single cell point-to-multipoint) and MBSFN (Multicast-Broadcast Single Frequency Network, Multicast/Multicast Single Frequency Network). Among them, in the transmission mode of SC-PTM, the transmission mode of MBMS configuration is: obtaining the subframe position of the MBMS control channel and the SC-RNTI (Single Cell-Radio Network Temporary Identity, single cell wireless network) of the MBMS control channel through SIB20 network temporary identifier), the UE obtains SC-MCCH (Single Cell MBMS Control Channel, single cell MBMS control channel) information by monitoring SC-RNTI at the subframe position of the MBMS control channel; the UE reads the SC-MCCH information and obtains MBMS The subframe position of the service channel and the G-RNTI (Rroup-Radio Network Temporary Identity, group wireless network temporary identifier) of the MBMS service information, the UE obtains the MBMS service by monitoring the G-RNTI at the subframe position of the MBMS service channel.

However, in the current 5G NR network, the MBS (Multicast Broadcast Service) transmission mode is PTM (Point to Multipoint, point-to-multipoint transmission) and PTP (Point to Point, point-to-point transmission) two transmission modes. The network side can determine the transmission mode of the MBS service according to the implementation of the MBS service, such as QoS parameters, channel quality, or the number of UEs (User equipment, user equipment) receiving the service, so that the network side has more flexible resource scheduling. Way. For example, in a cell, only one UE needs to receive the MBS service temporarily, and the PTP transmission mode can be selected. However, when multiple UEs need to receive MBS services at the same time, the PTM transmission mode can be selected. If the quality of the transmission channel borne by the current MBS service is poor and the QoS requirement of the MBS service is high, the network side will select the PTP transmission mode to ensure the transmission of the MBS service.

MBS services and transmission modes are different, so it is necessary to propose a transmission protocol for MBS configuration.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of a one-step transmission process according to an embodiment of the transmission method of the present application.

S110: Receive a system information block of the broadcast control channel, where the system information block includes the resource location of the MBS service channel, the wireless network temporary identifier used for the MBS service channel, and the related information of the MBS service.

The system information module received by the UE is sent by the base station through the broadcast control channel. The system information module may include the resource location of the MBS service channel, the wireless network temporary identifier used for the MBS service channel, and the related information of the MBS service, wherein the MBS service channel The service channel is used to carry the service information of the MBS, and is transmitted through PDSCH (Physical Downlink Share CHannel, downlink shared physical channel). The resource location of the MBS service channel can specifically be the location of the subframe on the physical channel, for example, the subframe of the MBS service. The frame is 10 time slots, and the information of the MBS traffic channel is in the first time slot. The wireless network temporary identifier used for the MBS service channel is the CRC part used to scramble the MBS service channel information, and can be used as the identifier of different UEs in the signal information between the UE and the base station. The relevant information of the MBS service is to distinguish the type of the MBS service. For example, the relevant information can be TMGI (Temporary Mobile Group Identity, temporary mobile group identity), and the UE can confirm whether the MBS service is the service required by the UE through the relevant information. .

S120: Decode and receive the MBS service by listening to the wireless network temporary identifier for the MBS service channel at the resource location of the MBS service channel.

The base station sends the MBS service data to the UE by mapping the MBS service channel to the PDSCH. The UE confirms that the MBS service is the service it needs through the relevant information of the MBS service, such as TMGI, and the UE obtains the resource location of the MBS service channel through the MBS service channel. The specific position of the required MBS service in the physical channel is known, for example, in the first time slot of the subframe, the UE can continuously monitor the wireless network temporary identifier used for the MBS service channel at this position. If the wireless network temporary identifier is obtained, the MBS service is decoded and received from the PDSCH.

In this embodiment, the configuration of the system information block and the configuration of the MBS control channel may be a single-cell configuration or a multi-cell configuration in a specific area. The configuration of the system information block is a single-cell configuration, that is, the system information block is valid only in this cell, and the configuration of the system information block is a multi-cell configuration in a specific area, that is, the system information block is valid in multiple cells in a specific area. The specific area may be an area of a plurality of adjacent cells. When the UE moves from one cell to another, it can continue to use the same system information block without reading the system information block of the new cell, which can save power consumption for the UE.

In the present application, the scheme of directly scheduling the MBS configuration through the system information block can shorten the overall transmission delay of the MBS configuration transmission, so that the UE can receive the MBS service in a shorter time.

In another embodiment, the content contained in the system information block of the MBS may be different, so the configuration transmission method of the MBS is also different. Please refer to FIG. 2 , which is a schematic diagram of a two-step transmission process according to an embodiment of the transmission method of the present application.

S210: Receive the system information block of the broadcast control channel, where the system information module includes the resource location of the MBS control channel and the wireless network temporary identifier used for the MBS control channel.

The system information module received by the UE is sent by the base station via the broadcast control channel. The system information module may include the resource location of the MBS control channel and the wireless network temporary identifier used for the MBS control channel, where the MBS control channel is used to carry the MBS The control information is transmitted through the PDSCH. The resource location of the MBS control channel can be the location of the subframe on the physical channel. For example, the subframe of the MBS service is 10 time slots, and the MBS control channel information is in the first time slot. . The wireless network temporary identifier used for the MBS control channel is the CRC part used to scramble the MBS control channel information, and can be used as the identifier of different UEs in the signal information between the UE and the base station.

S220: Decoding the received information of the MBS control channel by monitoring the wireless network temporary identifier for the MBS control channel at the resource location of the MBS control channel.

The base station sends the information of the MBS control channel to the UE by mapping the MBS control channel to the PDSCH, and the UE can know the specific location of the required information of the MBS control channel in the physical channel through the obtained resource location of the MBS control channel. In the first time slot of the subframe, the UE can continuously monitor the wireless network temporary identification used for the MBS control channel at this position. If the corresponding wireless network temporary identification is monitored, it will decode and receive the information of the MBS control channel from the PDSCH. .

S230: Read the information of the MBS control channel, obtain the resource position of the MBS service channel, the wireless network temporary identifier used for the MBS service channel, and the related information of the MBS service, and monitor the resource position of the MBS service channel by monitoring the information used for the MBS service channel. The wireless network is temporarily identified to decode and receive MBS services.

The base station sends the MBS service data to the UE by mapping the MBS service channel to the PDSCH, and the UE obtains the resource location of the MBS service channel, the wireless network temporary identifier used for the MBS service channel, and the MBS service by reading the information of the MBS control channel. Relevant information, where the relevant information of the MBS service is to distinguish the type of the MBS service. For example, the relevant information can be TMGI (Temporary Mobile Group Identity, temporary mobile group identity), and the UE can confirm whether the MBS service is its own through the relevant information. required business. According to the channel information of the MBS control channel, the specific position of the MBS service on the transmission channel is known. For example, in the second time slot of the subframe, if the UE confirms through TMGI that the MBS service is the service it needs, the UE can stay at this position for a continuous period of time. Monitor the wireless network temporary identifier used for the MBS service channel, and if the corresponding wireless network temporary identifier is monitored, decode and receive the MBS service from the PDSCH.

In this embodiment, the configuration of the system information block and the configuration of the MBS control channel may be a single-cell configuration or a multi-cell configuration in a specific area. The configuration of the system information block is a single-cell configuration, that is, the system information block is valid only in this cell, and the configuration of the system information block is a multi-cell configuration in a specific area, that is, the system information block is valid in multiple cells in a specific area. The specific area may be the area of multiple adjacent cells. When the UE moves from one cell to another, it can continue to use the same system information block without reading the system information block of the new cell, which can save power consumption for the UE. As for the configuration of the MBS control channel, since different cells may require different MBS services, in general, the configuration of the MBS control channel is a single-cell configuration. Of course, the configuration of the MBS control channel may also be a multi-cell configuration in a specific area, for example, in the case that the MBS services received by multiple cells are the same. Or, multiple users in multiple cells need to receive the same MBS service. In this case, the multiple users can be grouped and sent to multiple users in multiple cells using the same MBS control channel configuration. The same is true for the wireless network temporary identifier used for the MBS service channel carried by the channel, and multiple users of multiple cells can jointly monitor the wireless network temporary identifier used for the MBS service channel to receive the MBS service. Of course, in the case that the MBS services may be different, the configuration of the MBS control channel can also be configured for multiple cells in a specific area. For example, by grouping multiple MBS services into a group, the configuration of one MBS control channel is used to send to multiple users in multiple cells in a specific area, wherein the MBS control channel carries the wireless network temporary identifier used for the MBS service channel Similarly, multiple users of multiple cells jointly monitor the wireless network temporary identifier used for the MBS service channel to receive the MBS service.

Therefore, in the two-step transmission scheme for MBS configuration, there are combinations of the following four cases.

The configuration of the system information block is a multi-cell configuration in a specific area, and the configuration of the MBS control channel is a single-cell configuration.

The configuration of the system information block is a multi-cell configuration in a specific area, and the configuration of the MBS control channel is a multi-cell configuration in a specific area.

The configuration of the system information block is a single-cell configuration, and the configuration of the MBS control channel is a single-cell configuration.

The configuration of the system information block is a single-cell configuration, and the configuration of the MBS control channel is a multi-cell configuration in a specific area.

As described above, in the two-step transmission process, the UE receives the information of the MBS control channel through the system information block. In one embodiment, the MBS control channel is one, and the users of the cell where the UE is located all receive MBS services through the information of the MBS control channel, and the information of different MBS services, such as the temporary mobility group identifier that distinguishes the MBS service types. , are all configured by this one MBS control channel. The MBS control channel has a fixed repetition period and a change period. As shown in FIG. 3 , when the UE misses receiving the MBS control channel information, it needs to wait for the next repetition period of the MBS control channel to receive again. For the received modification notification sent by the base station, it is also necessary to wait for the next modification cycle of the MBS control channel to use the updated configuration before continuing to receive the MBS service. This is unfavorable for the UE to receive the MBS service with strict requirements on the delay, because if the repetition period and the change period of the MBS control channel are relatively long, the UE needs to wait for a long time to receive the MBS service. In addition, multiple different MBS services are configured through one MBS control channel. The UE may only need one of the MBS services, but the UE needs to decode and receive the information of the entire MBS control channel carrying the configuration of multiple MBS services to receive the MBS service. , which is also a waste of resources and power consumption for the UE.

In another embodiment, the UE receives the information of the MBS control channel through the system information block, and there are multiple MBS control channels, that is, in a cell, multiple MBS control channels are allowed to be configured. Scheduling is performed by grouping different MBS services into different MBS control channels. For example, the MBS service with stricter delay requirements is scheduled in one of the MBS control channels, and the repetition period and change period of the MBS control channel are set to be shorter, so that the UE receives the MBS control channel in the next repetition period or in the next repetition period. When changing the period to receive the updated configuration, the MBS service can be received without waiting for a long time. Or schedule MBS services with the same requirements from multiple users in one of the MBS control channels. The resource location of the MBS service channel configured in the MBS control channel and the wireless network temporary identifier used for the MBS service channel are the same and have the same Multiple users in need only need to decode and receive the MBS control channel, obtain the resource location of the corresponding MBS service channel and the wireless network temporary identifier used for the MBS service channel, and then monitor the corresponding resource location by monitoring the corresponding resource location. The wireless network temporary identification can receive the required MBS service. Therefore, by configuring multiple MBS service channels in one cell, different MBS services can be scheduled and controlled according to actual requirements, which can save the resources and power consumption of the UE.

In an embodiment, referring to FIG. 4 , receiving the system information block of the broadcast control channel may further include: sending a configuration request of the system information block to the base station through the UE, and after receiving the configuration request, the base station sends the system information to the UE. piece.

In the one-step transmission process, after the UE sends the configuration request of the system information block to the base station, after receiving the configuration request, the base station sends the configuration of the system information block through the broadcast control channel, and the system information block contains the configuration of the MBS service control channel, The UE can directly receive the MBS service according to the configuration of the system information block. Of course, as shown in FIG. 5 , before the base station sends the system information block to the UE, the base station may also send an acknowledgement message for the configuration request of the received system information block to the UE through the broadcast control channel to inform the UE that the system information block can be prepared. Configure reception.

In the two-step transmission process, after the UE sends the configuration request of the system information block to the base station, the base station sends the configuration of the system information block through the broadcast control channel after receiving the configuration request, and the UE decodes and receives the configuration according to the configuration of the system information block. The configuration of the MBS control channel is obtained by interpreting the MBS control channel to obtain the configuration of the MBS service control channel to receive the MBS service. Of course, as shown in FIG. 5 , before the base station sends the system information block to the UE, the base station may also send an acknowledgement message for the configuration request of the received system information block to the UE through the broadcast control channel to inform the UE that the system information block can be prepared. Configure reception.

In one embodiment, after the UE sends the configuration request of the system information block to the network side, it will continue to read the system information in the scheduling period of the next system information block (System information block, SIB), such as the scheduling period of SIB20 or SIBx. If the system information block is received in the next scheduling period, the UE sends a configuration request of the system information block to the network side again. If the UE continues to send the preset number of times in the UE system, the UE stops sending the configuration request of the system information block. The UE side considers that the MBS service cannot be received in this cell, and can only receive the MBS service through other means, such as cell handover. .

Through the on-demand broadcast method in which the UE sends the configuration request, the energy effect of the broadcast control channel for sending the broadcast can be improved, and the excessive signaling overhead in the case of multi-beam broadcast will not be caused. For example, there is currently no UE in the cell that needs to receive MBS services. If the energy effect of periodically broadcasting the system information of the system information block in the entire cell is very low, it will also cause waste of transmission resources. The on-demand broadcasting method of broadcasting the system information block after receiving the configuration request of the system information block solves this situation well, improves the broadcast energy effect, and does not cause waste of transmission resources.

In the two-step transmission of the MBS configuration in this application, the transmission of the configuration is not limited to the scheduling of the system information block. For example, in one case, the scheduling period of the system information block is longer, and the scheduling period of the MBS control channel Shorter, the information of the MBS control channel has been obtained through the system information block, so there is no need to wait for the scheduling period of the next system information block to obtain the MBS service as in the one-step transmission scheme, but only need to be read in the scheduling period of the next MBS control channel. The information of the MBS control channel, the resource location of the MBS service channel and the wireless network temporary identifier used for the MBS service channel are obtained to receive the MBS service. Therefore, when the scheduling time of the system information block is long, the two-step transmission scheme of the MBS configuration can shorten the transmission time for the UE to receive the MBS configuration.
