[0002] Multimedia Broadcast Multicast Service (MBMS) is a technology for transmitting data from a data source (for example, a network device) to multiple terminal devices by sharing network resources, which can effectively utilize network resources while providing multimedia services, and realize high-speed (for example, 256 kbps) multimedia service broadcast and multicast.

[0003] For MBMS services, a broadcast reception method without terminal feedback is adopted. In order to improve the reliability of data transmission, it is considered to introduce MBMS services that require feedback. If all terminals in an MBMS service group use a common feedback resource, the network device cannot distinguish the source of the feedback information, and thus cannot perform terminal device granularity directional data retransmission. Undifferentiated retransmission will also cause UEs that do not need retransmission to passively accept data retransmission, which is not conducive to terminal power saving. On the other hand, if all terminals in an MBMS service group are configured with UE granularity dedicated feedback resources, considering that the data reception feedback of many UEs in an MBMS group is similar, using independent feedback resources for each UE will also waste network side uplink resources to some extent.

[0004] Therefore, how to optimize the configuration of MBMS feedback resources to balance terminal power saving and improve resource utilization is an urgent problem to be solved. SUMMARY

[0050] In the embodiments of the present application, the "protocol" can refer to a standard protocol in the communication field, which can include LTE protocol, NR protocol, and related protocols applied to future communication systems, and the present application is not limited thereto.

[0051] In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional schemes, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0052] It should be understood that, in the embodiments of the present application, NR can also be independently deployed, and a new radio resource control (RRC) state, that is, an RRC_INACTIVE state, is defined in a 5G network environment for the purpose of reducing air interface signaling and quickly recovering wireless connection and quickly recovering data service. This state is different from RRC_IDLE and RRC_CONNECTED states.

[0053] In the RRC_IDLE state: mobility is based on terminal device cell selection reselection, paging is initiated by a core network (CN), and a paging area is configured by the CN. There is no terminal device access stratum (AS) context on the base station side, and there is no RRC connection.

[0054] In the RRC_CONNECTED state: there is an RRC connection, and there is a terminal device AS context between the base station and the terminal device. The network device knows the location of the terminal device is a specific cell level. Mobility is network device controlled mobility. Unicast data can be transmitted between the terminal device and the base station.

[0055] RRC_INACTIVE: mobility is based on terminal device cell selection reselection, there is a connection between the CN and the NR, the terminal device AS context exists on a certain base station, paging is triggered by a radio access network (RAN), a RAN-based paging area is managed by the RAN, and the network device knows the location of the terminal device is a RAN-based paging area level.

[0056] It should be noted that, in the embodiments of the present application, the inactive state can also be referred to as the deactivated state, and the present application does not limit this.

[0057] Multimedia broadcast multicast service (MBMS) is a technology for transmitting data from a data source (for example, a network device) to multiple terminal devices by sharing network resources, which can effectively utilize network resources while providing multimedia services, and realize high-speed (for example, 256 kbps) multimedia service broadcast and multicast.

[0058] In LTE / LTE-A, MBMS only has a broadcast bearer mode, and does not have a multicast bearer mode.

[0059] MBMS service reception is applicable to a UE in an RRC_CONNECTED or RRC_IDLE state.

[0060] In R13, Single Cell Point To Multiploint (SC-PTM) is introduced. SC-PTM is based on MBMS network architecture, and a Multi-cell / multicast Coordination Entity (MCE) decides whether to use SC-PTM transmission or Multicast Broadcast service Single Frequency Network (MBSFN) transmission.

[0061] In the related art, there is no terminal data reception feedback mechanism for MBMS services, and all are based on a broadcast reception method without feedback. In order to improve the reliability of data transmission, it is considered to introduce an MBMS service that requires feedback. If all terminals in an MBMS service group use a common feedback resource, the network device cannot distinguish the source of the feedback information, and thus cannot perform UE granularity directional data retransmission. Undifferentiated retransmission also causes UEs that do not need to be retransmitted to passively accept data retransmission, which is not conducive to terminal power saving. On the other hand, if all terminals in an MBMS service group are configured with UE granularity dedicated feedback resources, considering that the data reception feedback of many UEs in an MBMS group is similar, the use of independent feedback resources by each UE also wastes network side uplink resources to some extent.

[0062] Therefore, how to optimize the configuration of MBMS feedback resources to balance terminal power saving and improve resource utilization is an urgent problem to be solved.

[0063] Figure 2 A method 300 of wireless communication according to embodiments of the present application is shown in the schematic flowchart. The method 200 can be performed by a network device in a communication system as shown in Figure 1 The method 200 includes the following steps: Figure 2

[0064] S210, the terminal device acquires a reception condition of a point-to-multipoint (PTM) transmission from a network device in a first time period;

[0065] S220, the terminal device sends first information to the network device, the first information including the reception condition of the PTM transmission in the first time period acquired by the terminal device and / or decision information determined by the terminal device according to the reception condition.

[0066] Optionally, in the embodiments of the present application, the PTM transmission can refer to any kind of transmission mode of point-to-multipoint, such as groupcast transmission, broadcast transmission or multicast transmission, etc. ​

[0067] In the embodiments of the present application, the network device can perform PTM transmission through a physical downlink shared channel (PDSCH). That is, the PTM transmission can be carried in the PDSCH. In other embodiments, the PTM transmission can be carried in other data channels, which are not limited in the embodiments of the present application.

[0068] It should be understood that the embodiments of the present application do not specifically limit the number of terminal devices for which the network device performs PTM transmission.

[0069] In the embodiments of the present application, the plurality of terminal devices corresponding to one PTM transmission can be considered as one PTM data receiving group, and the network device performs PTM transmission in units of the PTM data receiving group.

[0070] Optionally, in some embodiments, the first information can be sent through radio resource control (RRC) dedicated signaling, that is, the first information is not transmitted on the feedback resource configured by the network device, but is sent through a control channel.

[0071] Optionally, in some embodiments, the first information can include time information of the terminal device for counting the reception of the PTM transmission, that is, the time information corresponding to the first time period.

[0072] It should be understood that the present application does not limit the indication manner of the time information corresponding to the first time period.

[0073] In some embodiments, the time information corresponding to the first time period can be indicated in a relative duration manner, for example, the time information corresponding to the first time period includes a first time and a first duration, and the first time period is a time period of the first duration before the first time, that is, the first duration is counted backward from the first time.

[0074] Optionally, the first time can be the sending time of the first information, that is, the reporting time of the first information can be used as a reference, and in other embodiments, other time can also be used as a reference, which is not limited in the present application.

[0075] In other embodiments, the time information corresponding to the first time period can be indicated in an absolute duration manner, for example, the first time period can be indicated in a statistical time window manner, in which case, the time information corresponding to the first time period can include the start time and the end time of the first time period.

[0076] Optionally, in some embodiments, the terminal device can further send assistance information for resource configuration to the network device. Optionally, the assistance information can comprise decision information for subsequent data transmission determined by the terminal device according to the reception of the PTM transmission in the period of time, and the decision information is further sent to the network device, so that the network device performs resource configuration according to the decision information.

[0077] By way of example and not limitation, the decision information is used to indicate at least one of the following:

[0078] feedback resource expected by the terminal device for feeding back the PTM transmission;

[0079] dedicated feedback resource required by the terminal device for feeding back the PTM transmission;

[0080] the terminal device expects to receive broadcast or multicast data in a Point To Point (PTP) mode;

[0081] the terminal device expects to leave the current PTM data receiving group.

[0082] For example, the terminal device can determine that the network device needs to allocate common feedback resource in the case of good reception.

[0083] For another example, the terminal device can determine that the network device needs to allocate dedicated feedback resource, or expects to receive data of the network device in a Point To Point (PTP) mode, or leave the current PTM data receiving group in the case of poor reception.

[0084] In the embodiments of the present application, the terminal device notifies the network device of the reception of the PTM transmission in a period of time, so that the network device can perform resource configuration for the PTM receiving group according to the reception, to achieve the balance between improving resource utilization and power saving of the terminal device.

[0085] Optionally, the resource herein can comprise feedback resource for feeding back whether the reception of the PTM transmission is successful, PTM or PTP configuration for downlink data reception, such as Data Radio Bearer (DRB) configuration, Radio Link Control (RLC) configuration, Media Access Control (MAC) layer configuration or physical layer (layer 1) configuration, etc., which can be used to implement conversion from PTM to PTP mode.

[0086] For example, in the case that the terminal device has good reception, a common feedback resource is configured, and in the case that the terminal device has poor reception, a dedicated feedback resource is configured.

[0087] Optionally, in some embodiments, the reception condition of the PTM transmission in the first time period includes at least one of the following:

[0088] the reception condition of the PTM transmission in the first time period, which is counted by the MAC layer of the terminal device, or the reception condition of the PTM transmission in the first time period, which is counted by the MAC layer of the terminal device;

[0091] Optionally, in some embodiments, the reception condition of the PTM transmission counted by the MAC layer of the terminal device can be in the granularity of the terminal device. For example, the reception condition can include the reception condition of the PTM transmission corresponding to all HARQ processes of the terminal device, which is counted by the MAC layer of the terminal device, that is, the reception condition of the PTM transmission corresponding to all HARQ processes is counted in a combined manner.

[0092] Optionally, the HARQ process of the terminal device can include all downlink HARQ processes configured by the network device to the terminal device, or can also include the downlink HARQ process actually used by the network device for PTM transmission.

[0093] In some embodiments, the reception condition of the PTM transmission counted by the MAC layer of the terminal device can refer to the reception success condition, the reception failure condition, the condition of needing to feed back a HARQ NACK, the condition of needing to feed back a HARQ ACK, and other related information of the MAC layer data, and the application is not limited thereto.

[0094] Optionally, the MAC layer data can include a MAC service data unit (SDU).

[0095] Example one:

[0096] The receiving condition of the PTM transmission of the media access control (MAC) layer statistics of the terminal device in the first time period includes at least one of the following:

[0097] The number of times of needing to feed back a hybrid automatic repeat request negative acknowledgement (HARQ NACK) in the first time period;

[0098] The number of times of needing to feed back a hybrid automatic repeat request acknowledgement (HARQ ACK) in the first time period;

[0104] The proportion information of the MAC SDUs that are successfully received in the first time period in all the MAC SDUs received in the first time period.

[0105] In the above example one, the receiving condition of the MAC layer statistics is in the granularity of the terminal device, or in other words, the receiving conditions of all the HARQ processes are combined and counted.

[0106] Example two:

[0107] The receiving condition of the PTM transmission of the MAC layer statistics of the terminal device includes at least one of the following:

[0115] a proportion of MAC SDUs corresponding to each HARQ process of the terminal device in the first time period that are successfully received, to all MAC SDUs received in the first time period.

[0116] In the above example two, the receiving status of the MAC layer statistics is in the granularity of the HARQ process, or in other words, the receiving status of each HARQ process is individually counted.

[0117] It should be understood that, in the embodiments of the present application, the number of receiving failures of the same data can be recorded in a combined manner, i.e., the multiple receiving failure events of the data can be recorded only once, or the number of receiving failures of the same data can be recorded independently, i.e., each receiving failure event of the data is recorded only once.

[0118] In some embodiments, the receiving status of the PTM transmission of the RLC layer statistics of the terminal device can refer to the receiving success status of the RLC layer data, the receiving failure status, and other related information, and the present application is not limited thereto.

[0123] The number of RLC SDUs that fail to be received in the first time period;

[0124] The proportion of the RLC SDUs that fail to be received in the first time period in all RLC SDUs received in the first time period;

[0261] S202, the terminal device receives third configuration information sent by the network device, and the third configuration information is used to configure at least one reporting condition of the terminal device reporting the first information.

[0262] In some embodiments, in the case where the network device configures the at least one reporting condition, the terminal device can report the first information according to the at least one reporting condition.

[0263] For example, in S204, the terminal device can report the first information in the case where the first reporting condition is met.

[0264] Optionally, in some embodiments, the terminal device can further send the first message to the network device in the case where it is determined that the reporting condition is met, and send the first information to the network device in the case where the first response message is received.

[0265] Optionally, in some other embodiments, as shown in Figure 4 the method 200 further includes:

[0266] The terminal device receives a second message sent by the network device, and the second message is used to activate one or more reporting conditions in the at least one reporting condition.

[0267] That is, the network device can activate part of the at least one configured reporting condition, and further, the terminal device can report the first information according to the activated reporting condition. In this case, the first reporting condition can be a configured and activated reporting condition.

[0268] Optionally, in some embodiments, the second message comprises at least one of the following:

[0269] Downlink Control Information (DCI), MAC signaling, Radio Resource Control (RRC) signaling.

[0270] That is, the network device can activate the reporting condition through DCI, MAC signaling, or RRC signaling.

[0271] It should be understood that the present application does not limit the activation mode of the reporting condition, and the following takes activating the reporting condition through DCI as an example for description, and the activation mode through other signaling is similar, which will not be described here for brevity.

[0272] As an example, the second message can comprise first indication information, which is used to indicate whether all of the at least one reporting condition are activated, for example, the first indication information can be 1 bit, and the value 1 indicates that all of the at least one reporting condition are activated, and the value 0 indicates that none of the at least one reporting condition is activated.

[0273] As another example, the bitmap mode can be used for indication. For example, the second message can comprise second indication information, which comprises at least one bit, each bit of the at least one bit corresponds to one reporting condition of the at least one reporting condition, and the value of each bit is used to indicate whether the corresponding reporting condition is activated, for example, the value 1 indicates that the reporting condition is activated, and the value 0 indicates that the reporting condition is not activated. For example, the at least one reporting condition comprises four reporting conditions, and the second indication information can comprise four bits, each bit corresponds to one reporting condition, and if the value of the second indication information is 1001, it indicates that the first and fourth reporting conditions are activated.

[0274] In some embodiments, the second indication information can be carried in a reserved field of DCI or a newly added field, which is not limited by the present application.

[0275] As yet another example, the second message can comprise third indication information, each reporting condition of the at least one reporting condition corresponds to a corresponding identifier, the third indication information can comprise at least one bit, and the value of the at least one bit has a corresponding relationship with the identifier of the reporting condition, so that the activated reporting condition can be determined according to the value of the at least one bit. For example, the at least one reporting condition comprises eight reporting conditions (denoted as reporting condition 0 to reporting condition 7), and the third indication information can comprise three bits, and different values of the three bits can indicate different reporting conditions of the eight reporting conditions, for example, the value 000 indicates that the reporting condition 0 is activated, and the value 100 indicates that the reporting condition 4 is activated.

[0276] In summary, the terminal device can feed back the reception status of the PTM transmission and / or decision information according to the reception status to the network device, so that the network device can perform resource configuration on the PTM reception group corresponding to the PTM transmission according to the reception status and / or the decision information, which is beneficial to taking into account the improvement of resource utilization and the power saving requirement of the terminal.
