In the NR system, unicast of a Radio Resource Control (RRC) connection state is fed back by a Hybrid Automatic Repeat reQuest (HARQ). However, the multicast broadcast of other systems does not introduce a feedback mechanism, that is, the terminal device receives the multicast or broadcast service without feedback, and the loss has no remedial measure.

In some services in NR, for example, services in scenarios such as V2X and industrial internet, the reliability requirement for multicast broadcast transmission is higher and higher, so a feedback mechanism is introduced for multicast broadcast to ensure the reliability of service transmission, so as to ensure that all members in a group receive service data. Therefore, in order to improve the reliability of service transmission, an uplink feedback mechanism for multicast broadcast service needs to be introduced, so that the network can determine whether retransmission needs to be initiated according to the feedback information.

Multimedia Broadcast Multicast Service (MBMS) is a technology for transmitting data from one data source to a plurality of terminal devices by sharing network resources, and can effectively utilize the network resources while providing Multimedia services, thereby realizing Broadcast and Multicast of Multimedia services at a higher rate (256 kbps). In addition, the reception of the MBMS service is applicable to the terminal device in an RRC CONNECTED state (RRC _ CONNECTED) or an RRC IDLE state (RRC _ IDLE) or an RRC deactivated state (RRC _ INACTIVE) state.

In order to improve reliability of the MBMS service, a feedback mechanism for the MBMS service needs to be introduced, and how to configure a Physical Uplink Control Channel (PUCCH) transmission resource to support the feedback mechanism of the MBMS service is a problem to be solved.

Based on the above problem, the present application provides a scheme for determining a PUCCH transmission resource, where for a service sent in a multicast or broadcast manner, a terminal device can determine the PUCCH transmission resource for uplink feedback, so that uplink feedback can be performed on the service sent in the multicast or broadcast manner, so as to improve reliability of multicast or broadcast transmission.

The technical solution of the present application is detailed below by specific examples.

Fig. 2 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, and as shown in fig. 2, the method 200 may include at least some of the following:

s210, the terminal equipment determines a target PUCCH transmission resource from at least one PUCCH transmission resource set,

Optionally, the first type service is an MBMS service. Of course, the first type service may also be another service transmitted in a multicast or broadcast manner, which is not limited in this application.

In this embodiment of the present application, the terminal device receives a Physical Downlink Control Channel (PDCCH) sent by a network device, where the PDCCH includes Downlink Control Information (DCI), and the DCI is used to schedule a Physical Downlink Shared Channel (PDSCH) resource. The terminal device receives the PDSCH carrying the first type of service sent by the network device on the PDSCH resource scheduled by the DCI, and after determining the target PUCCH transmission resource, the terminal device may send a PUCCH to the network device on the target PUCCH transmission resource, where the PUCCH carries uplink feedback information of the first type of service.

Optionally, the uplink feedback information may be HARQ feedback. For example, if the terminal device successfully receives the first type of service, the terminal device feeds back an Acknowledgement (ACK), or the terminal device feeds back nothing. For another example, if the terminal device fails to receive the first type service, the terminal device feeds back a Negative Acknowledgement (NACK).

Optionally, in this embodiment of the present application, S210 may specifically be:

the terminal equipment determines the target PUCCH transmission resource from the at least one PUCCH transmission resource set according to the first information, and/or the terminal equipment determines a first PUCCH transmission resource set from the at least one PUCCH transmission resource set according to the first information, wherein the first PUCCH transmission resource set comprises the target PUCCH transmission resource;

wherein the first information includes, but is not limited to, at least one of:

reference Signal Received Power (RSRP) measurement results, radio Network Temporary Identifier (RNTI) of the terminal device, intra-group Identity in a communication group where the terminal device is located, and indication information in DCI for scheduling PDSCH carrying the first type of service.

Alternatively, the terminal device may determine the target PUCCH transmission resource by the following schemes in examples 1 to 8.

Example 1, the terminal device determines the target PUCCH transmission resource from the at least one PUCCH transmission resource set according to an intra-group identifier in a communication group in which the terminal device is located.

It should be noted that, for multicast communication, each terminal is usually configured with an independent intra-group identifier (group identity), that is, an intra-group identifier in a communication group in which the terminal device is located, and when the network device configures a PUCCH transmission resource set for the terminal device, the terminal device may determine a corresponding PUCCH transmission resource from the PUCCH transmission resource set according to the intra-group identifier in the communication group, so that each intra-group terminal may have an independent PUCCH transmission resource.

For example, a communication group comprises 4 terminal devices for which the network device is a network deviceThe allocated Identifiers (IDs) in the group are UE ID #0, UE ID #1, UE ID #2, and UE ID #3, respectively, the PUCCH transmission resource set configured by the network device includes 8 PUCCH transmission resources, and when the network device transmits the multicast PDSCH, each terminal device determines the corresponding PUCCH transmission resource in the PUCCH transmission resource set according to the Identifier (ID) in the respective group. For example, R _PUCCH = mod (UE _ ID, M), where M represents the number of PUCCH transmission resources in the PUCCH transmission resource set, R _PUCCH Denotes an index of the determined target PUCCH transmission resource, and mod () denotes a modulo operation. As shown in fig. 3, UE ID #0 corresponds to PUCCH transmission resource #0, UE ID #1 corresponds to PUCCH transmission resource #1, UE ID #2 corresponds to PUCCH transmission resource #2, and UE ID #3 corresponds to PUCCH transmission resource #3.

For another example, PUCCH resources in all PUCCH transmission resource sets are numbered, and the terminal device determines a corresponding PUCCH transmission resource set and a specific target PUCCH transmission resource according to an intra-group identifier in the communication group in which the terminal device is located. As shown in fig. 4, it is assumed that the at least one PUCCH transmission resource set includes two PUCCH transmission resource sets, which are denoted as PUCCH transmission resource set 0 and PUCCH transmission resource set 1, respectively, and PUCCH transmission resource set 0 includes 8 PUCCH transmission resources, and PUCCH transmission resource set 1 includes 4 PUCCH transmission resources, which are numbered uniformly, that is, the index of PUCCH transmission resource is [0,11]The terminal equipment determines corresponding PUCCH transmission resources, such as R, according to the intra-group identification in the communication group where the terminal equipment is located _PUCCH = mod (UE _ ID, M), M denotes the number of PUCCH transmission resources in all PUCCH transmission resource sets, R _PUCCH Represents an index of the determined target PUCCH transmission resource, and mod () represents a modulo operation. Wherein M =12, that is, the total number of all PUCCH transmission resources, when UE _ ID =1, the determined target PUCCH transmission resource index is 1, and is located in the second PUCCH transmission resource in PUCCH transmission resource set 0; when UE _ ID =10, the determined target PUCCH transmission resource index is 10, and is located in the third PUCCH transmission resource in PUCCH transmission resource set 1.

For another example, as shown in fig. 5, it is assumed that the at least one PUCCH transmission resource set includes two PUCCH transmission resource sets, which are respectively denoted as PUCCH transmission resourcesSet 0 and PUCCH transmission resource set 1, and PUCCH transmission resource set 0 includes 8 PUCCH transmission resources with index of [0,7 ]]The PUCCH transmission resource set 1 includes 4 PUCCH transmission resources, and the index of the PUCCH transmission resource is [0,3 ]]The terminal equipment firstly determines a PUCCH transmission resource set according to an in-group identifier in a communication group where the terminal equipment is located, such as S _PUCCH = mod (UE _ ID, N), where N represents the number of PUCCH transmission resource sets 2,S _PUCCH Denotes an index of the determined PUCCH transmission resource set, and mod () denotes a modulo operation. Further, the terminal equipment determines PUCCH transmission resources according to the intra-group identification in the communication group where the terminal equipment is located, R _PUCCH = mod (UE _ ID, M), where M represents the number of PUCCH transmission resources included in the PUCCH transmission resource set, R _PUCCH Represents an index of the determined target PUCCH transmission resource, and mod () represents a modulo operation. For PUCCH transmission resource set 0, m =8; for PUCCH transmission resource set 1, m =4. When the UE _ ID =1, the determined index of the PUCCH transmission resource set is 1, that is, the second PUCCH transmission resource set, and the determined target PUCCH transmission resource index is 1, that is, the second PUCCH transmission resource in the PUCCH transmission resource set 1; when UE _ ID =6, the index of the determined PUCCH transmission resource set is 0, i.e., the first PUCCH transmission resource set, and the index of the determined target PUCCH transmission resource is 6, i.e., the seventh PUCCH transmission resource in PUCCH transmission resource set 0.

Optionally, in example 1, when the terminal device determines a plurality of PUCCH transmission resources from the at least one PUCCH transmission resource set according to the intra-group identifier in the communication group in which the terminal device is located, the terminal device determines a first PUCCH transmission resource in the plurality of PUCCH transmission resources as the target PUCCH transmission resource, or determines a randomly selected PUCCH transmission resource in the plurality of PUCCH transmission resources as the target PUCCH transmission resource.

Example 2, the terminal device determines, according to an intra-group identifier in a communication group in which the terminal device is located, a first PUCCH transmission resource set from the at least one PUCCH transmission resource set; and the terminal equipment determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to at least one of RSRP measurement results, RNTI of the terminal equipment and indication information in DCI used for scheduling the PDSCH carrying the first type service.

Optionally, in example 2, in a case that the number of the at least one PUCCH transmission resource set is greater than 1, the terminal device may determine, according to an intra-group identifier in a communication group in which the terminal device is located, a first PUCCH transmission resource set from the at least one PUCCH transmission resource set. For example, S _PUCCH = mod (UE _ ID, N), where N represents the number of PUCCH transmission resource sets, S _PUCCH Denotes an index of the determined PUCCH transmission resource set, i.e., an index of the first PUCCH transmission resource set, and mod () denotes a modulo operation.

In example 2, the terminal device determines the target PUCCH transmission resource from the first set of PUCCH transmission resources, for example, in accordance with RSRP measurement results. Assuming that the first PUCCH transmission resource set includes 3 PUCCH transmission resources, wherein PUCCH transmission resource #0 corresponds to RSRP range 0, PUCCH transmission resource #1 corresponds to RSRP range 1, PUCCH transmission resource #2 corresponds to RSRP range 2, in this case, assuming that RSRP measurement result measured by the terminal device belongs to RSRP range 1, the target PUCCH transmission resource is PUCCH transmission resource #1.

For example, as shown in fig. 6, the network device configures 3 RSRP thresholds, which are respectively denoted as RSRP-THD1, RSRP-THD2, RSRP-THD3, and configures 4 PUCCH transmission resources, which are respectively denoted as PUCCH transmission resource #0, PUCCH transmission resource #1, PUCCH transmission resource #2, PUCCH transmission resource #3, different RSRP ranges correspond to different PUCCH resources, frequency-division multiplexing (FDM), time-division multiplexing (TDM), or code-division multiplexing (CDM) between the plurality of PUCCH transmission resources, and the terminal device receives MBMS data transmitted by the network device and determines that no MBMS data is transmitted according to a downlink Signal (e.g., a synchronization Signal block/physical broadcast Channel block (synchronization/physical broadcast Channel block, SS/CDM), a Channel State Information Reference Signal (Channel State Information, reference, etc.), and if no measurement of the RSRP transmission resource corresponds to a currently measured PUCCH transmission resource, no measurement of the uplink transmission resource is performed according to the current RSRP transmission resource, and if no measurement of the downlink transmission resource corresponds to the current RSRP transmission resource. In an embodiment, the network device configures a correspondence between RSRP ranges and PUCCH resources.

In example 2, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set, for example, based on the RNTI of the terminal device. For example, R _PUCCH = mod (UE _ RNTI, M), where UE _ RNTI represents RNTI of the terminal device, M represents the number of PUCCH transmission resources in the first PUCCH transmission resource set, and R represents _PUCCH Denotes an index of the determined target PUCCH transmission resource, and mod () denotes a modulo operation.

In example 2, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to indication information in DCI used to schedule the PDSCH carrying the first type of traffic. For example, if the indication information is an index of the target PUCCH transmission resource, the terminal device may determine the target PUCCH transmission resource according to the indication information.

Example 3, the terminal device determines the target PUCCH transmission resource from the at least one PUCCH transmission resource set based on the RNTI of the terminal device. For example, R _PUCCH = mod (UE _ RNTI, M), where UE _ RNTI represents RNTI of the terminal device, M represents the number of PUCCH transmission resources in the PUCCH transmission resource set, and R represents the number of PUCCH transmission resources in the PUCCH transmission resource set _PUCCH Denotes an index of the determined target PUCCH transmission resource, and mod () denotes a modulo operation.

Example 4, the terminal device determines a first PUCCH transmission resource set from the at least one PUCCH transmission resource set based on the RNTI of the terminal device; and the terminal equipment determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to at least one of the RSRP measurement result, the intra-group identification in the communication group where the terminal equipment is located, and the indication information in the DCI used for scheduling the PDSCH carrying the first type of service.

Alternatively, in example 4In case that the number of the at least one PUCCH transmission resource sets is greater than 1, the terminal device may determine the first PUCCH transmission resource set from the at least one PUCCH transmission resource set according to the RNTI of the terminal device. For example, S _PUCCH = mod (UE _ RNTI, N), where UE _ RNTI represents RNTI for the terminal device, N represents the number of PUCCH transmission resource sets, S _PUCCH Denotes an index of the determined PUCCH transmission resource set, i.e., an index of the first PUCCH transmission resource set, and mod () denotes a modulo operation.

In example 4, the terminal device determines the target PUCCH transmission resource from the first set of PUCCH transmission resources, for example, in accordance with RSRP measurement results. It is assumed that the first set of PUCCH transmission resources comprises 4 PUCCH transmission resources, wherein PUCCH transmission resource #0 corresponds to RSRP range 0, PUCCH transmission resource #1 corresponds to RSRP range 1, PUCCH transmission resource #2 corresponds to RSRP range 2, PUCCH transmission resource #3 corresponds to RSRP range 3. In this case, assuming that the RSRP measurement result measured by the terminal device belongs to RSRP range 2, the target PUCCH transmission resource is PUCCH transmission resource #2.

In example 4, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to an intra-group identity of the communication group in which the terminal device is located, for example. For example, R _PUCCH = mod (UE _ ID, M), where UE _ ID represents an intra-group identity within a communication group in which the terminal device is located, M represents the number of PUCCH transmission resources in the first PUCCH transmission resource set, R represents _PUCCH Denotes an index of the determined target PUCCH transmission resource, and mod () denotes a modulo operation.

In example 4, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to indication information in DCI used to schedule the PDSCH carrying the first type of traffic. For example, the indication information is an index of the target PUCCH transmission resource, and the terminal device may determine the target PUCCH transmission resource according to the indication information.

Example 5, the terminal device determines the target PUCCH transmission resource from the at least one PUCCH transmission resource set in dependence on the RSRP measurement.

Optionally, in example 5, the terminal device determines the target PUCCH transmission resource from the at least one PUCCH transmission resource set according to the RSRP measurement result, at least one RSRP threshold, and a first correspondence, where the first correspondence is a correspondence of an RSRP range and a PUCCH transmission resource.

It should be noted that the at least one RSRP threshold is used to determine an RSRP range.

For example, in the first correspondence, PUCCH transmission resource #0 corresponds to RSRP range 0, PUCCH transmission resource #1 corresponds to RSRP range 1, and PUCCH transmission resource #2 corresponds to RSRP range 2. Assuming that the PUCCH transmission resource set includes 3 PUCCH transmission resources, wherein PUCCH transmission resource #0 corresponds to RSRP range 0, PUCCH transmission resource #1 corresponds to RSRP range 1, and PUCCH transmission resource #2 corresponds to RSRP range 2, in this case, assuming that the RSRP measurement result measured by the terminal device belongs to RSRP range 1, the target PUCCH transmission resource is PUCCH transmission resource #1.

Optionally, the at least one RSRP threshold is pre-configured or protocol agreed, or the at least one RSRP threshold is configured by the network device.

Optionally, the first correspondence is pre-configured or agreed upon by a protocol, or the first correspondence is configured by a network device.

In example 6, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set, for example, according to an intra-group identity within a communication group in which the terminal device is located. For example, R _PUCCH = mod (UE _ ID, M), where UE _ ID represents an intra-group identity within a communication group in which the terminal device is located, and M representsNumber of PUCCH transmission resources, R, in a first PUCCH transmission resource set _PUCCH Represents an index of the determined target PUCCH transmission resource, and mod () represents a modulo operation.

In example 6, the terminal device determines the target PUCCH transmission resource from the first set of PUCCH transmission resources, e.g. based on the RNTI of the terminal device.

In example 6, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to indication information in DCI used to schedule the PDSCH carrying the first type of traffic. For example, the indication information is an index of the target PUCCH transmission resource, and the terminal device may determine the target PUCCH transmission resource according to the indication information.

Example 7, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to indication information in DCI used to schedule the PDSCH carrying the first type of traffic; or,

the terminal equipment determines a first PUCCH transmission resource set from the first PUCCH transmission resource set according to indication information in DCI (downlink control information) for scheduling PDSCH carrying the first type of service, wherein the first PUCCH transmission resource set comprises the target PUCCH transmission resource.

Example 8, the terminal device determines a first PUCCH transmission resource set from the at least one PUCCH transmission resource set according to indication information in DCI used to schedule the PDSCH carrying the first type of traffic; and the terminal equipment determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to at least one of the RSRP measurement result, the intra-group identification in the communication group where the terminal equipment is located and the RNTI of the terminal equipment.

In example 8, the terminal device determines the target PUCCH transmission resource from the first set of PUCCH transmission resources, for example, in accordance with RSRP measurement results. It is assumed that the first PUCCH transmission resource set includes 4 PUCCH transmission resources, wherein PUCCH transmission resource #0 corresponds to RSRP range 0, PUCCH transmission resource #1 corresponds to RSRP range 1, PUCCH transmission resource #2 corresponds to RSRP range 2, PUCCH transmission resource #3 corresponds to RSRP range 3. In this case, assuming that the RSRP measurement result measured by the terminal device belongs to RSRP range 2, the target PUCCH transmission resource is PUCCH transmission resource #2.

In example 8, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set, for example, according to an intra-group identity within a communication group in which the terminal device is located. For example, R _PUCCH = mod (UE _ ID, M), where UE _ ID represents an intra-group identity within a communication group in which the terminal device is located, M represents the number of PUCCH transmission resources in the first PUCCH transmission resource set, R represents _PUCCH Denotes an index of the determined target PUCCH transmission resource, and mod () denotes a modulo operation.

In example 8, the terminal device determines the target PUCCH transmission resource from the first set of PUCCH transmission resources, e.g. based on the RNTI of the terminal device. For example, R _PUCCH = mod (UE _ RNTI, M), where UE _ RNTI represents RNTI of the terminal device, M represents the number of PUCCH transmission resources in the first PUCCH transmission resource set, and R represents _PUCCH Denotes an index of the determined target PUCCH transmission resource, and mod () denotes a modulo operation.

Optionally, in this embodiment of the present application, the RNTI of the terminal device includes at least one of the following:

cell RNTI (Cell-RNTI, C-RNTI), multicast RNTI (Group-RNTI, G-RNTI), broadcast RNTI (Broadcast-RNTI, B-RNTI).

Optionally, in some embodiments, the at least one PUCCH transmission resource set is configured for the network device by common signaling or user-specific signaling.

Optionally, when the at least one PUCCH transmission resource set is configured by the network device through the user dedicated signaling, the network device configures the same PUCCH transmission resource set for the terminal device corresponding to the first type of service.

Optionally, the common signaling comprises at least one of:

system Information Block (SIB) Information, cell-specific RRC signaling.

Optionally, in some embodiments, the at least one PUCCH transmission resource set includes only one PUCCH transmission resource set, and all terminal devices corresponding to the first type of traffic share the same PUCCH transmission resource.

It should be noted that, assuming that the first type service is an MBMS service, terminals of the MBMS share PUCCH transmission resources, that is, a plurality of terminals use the same PUCCH transmission resource, and therefore, the plurality of terminals determine the same PUCCH transmission resource. In this case, for example, the target PUCCH transmission resource used for transmitting the uplink feedback information carrying the MBMS service may be determined in the following manners 1 to 3.

Mode 1: specific target PUCCH transmission resources are indicated in DCI scheduling PDSCH carrying MBMS.

Mode 2: only one PUCCH transmission resource is configured for MBMS services.

Mode 3: the RSRP threshold is set to infinitesimal (or infinitesimal) when all RSRP results measured by the UEs are within the same RSRP range, and thus the same PUCCH transmission resource can be determined.

Optionally, in some embodiments, the at least one PUCCH transmission resource set includes only one PUCCH transmission resource set, and all terminal devices corresponding to the first type of traffic each use an independent PUCCH transmission resource.

In order to use independent PUCCH transmission resources between terminals, the terminals need to be able to determine independent PUCCH transmission resources from a PUCCH transmission resource set according to parameters. Since DCI scheduling PDSCH is transmitted to a group of terminals, it is impossible to indicate PUCCH transmission resources of each terminal through DCI. Specifically, for example, the terminal may determine a corresponding PUCCH transmission resource in the PUCCH transmission resource set according to the intra-group ID. Since the intra-group ID of each terminal is different, an independent PUCCH transmission resource can be determined.

Optionally, in some embodiments, the at least one PUCCH transmission resource set includes only one PUCCH transmission resource set, and one PUCCH transmission resource is shared among a group of terminal devices corresponding to the first type of traffic. In this case, for example, the terminal device may determine PUCCH transmission resources from the intra-group ID. When the number of the PUCCH transmission resources configured by the network equipment is smaller than the number of the terminal equipment in the communication group, a plurality of terminals can share one PUCCH transmission resource. For example, the network device configures a PUCCH transmission resource set including 4 PUCCH transmission resources, but the receiving terminal of multicast communication includes 12 terminals, and at this time, a plurality of terminals share one PUCCH transmission resource. When the terminal determines the PUCCH transmission resource according to the intra-group ID, such as R _PUCCH = mod (UE _ ID, M), where M represents the number of PUCCH transmission resources, and the range of UE _ ID is [0,11 [ ]]Mod () represents a modulo operation, and according to calculation, terminals with UE _ IDs of 0, 4, and 8 share one PUCCH transmission resource, and similarly, terminals with UE _ IDs of 1, 5, and 9 share one PUCCH transmission resource; terminals with UE _ ID 2, 6, 10, UE_id 3, 7, 11 share two other PUCCH transmission resources.

For multicast broadcast services, data transmitted by a network device needs to be received by multiple terminals, which may be located at different locations in a cell. For the frequency Range 2 (frequency Range 2, fr2), the corresponding frequency is usually high frequency, for example, 24.25GHz-52.6GHz, in order to ensure the coverage, the network device usually transmits data in a beamforming manner, and in order to ensure that all terminal devices can receive MBMS data, the network device usually transmits MBMS data once using all beams, and the network transmits data using different beams at different times, so that terminals located at different positions in a cell may correctly receive the data. One PUCCH resource is indicated in DCI transmitted using different beams, and a user receiving the DCI performs feedback using the PUCCH resource indicated by the DCI. As shown in fig. 7, the network device (gNB) transmits MBMS data by 4 beams in turn at 4 moments (moment 1, moment 2, moment 3, and moment 4), the ellipses shown in fig. 7 correspond to beam 0, beam 1, beam 2, and beam 3 from left to right, respectively, the terminal device detects MBMS data on each beam, respectively, and if the detection is successful in at least one direction, the detection of the MBMS data is considered to be successful, and if the detection is not successful in all directions, the detection of the MBMS data is considered to be failed. The network device configures PUCCH resources used by the terminal device to send uplink feedback information, where 4 beams in fig. 7 correspond to 4 PUCCH transmission resources in fig. 8, each PUCCH transmission resource includes PUCCH-ACK resources and PUCCH-NACK resources, the PUCCH-ACK resources are used by the terminal device to send Acknowledgement (ACK) information to the network, the PUCCH-NACK resources are used by the terminal device to send Negative Acknowledgement (NACK) information to the network, and the PUCCH resources are behind all time domain resources used for transmitting the MBMS data, so that the terminal device can determine whether detection is successful according to detection results of MBMS data sent in all directions.

Optionally, in some embodiments, the at least one PUCCH transmission resource set includes multiple PUCCH transmission resource sets, and all terminal devices corresponding to the first type of traffic share the same PUCCH transmission resource. In this case, in order to enable multiple terminals to share the same PUCCH transmission resource, the same PUCCH transmission resource set needs to be selected first. For example, a PUCCH transmission resource set is indicated in the DCI, and a PUCCH transmission resource index is indicated; and all the terminals receiving the DCI determine corresponding transmission resource sets according to the indication information and determine the transmission resources in the transmission resource sets. For another example, the DCI indicates a PUCCH transmission resource set, and the PUCCH transmission resource is determined by RSRP measurement results; the terminal determines a specific PUCCH transmission resource set according to the DCI indication information, determines specific PUCCH transmission resources in the set according to the RSRP measurement result, sets the RSRP threshold to be infinite (or infinite), and all terminals are in the same RSRP range, so that the same PUCCH transmission resources can be determined. For another example, a PUCCH transmission resource set is determined according to the RSRP measurement result, and the PUCCH transmission resource is indicated by DCI: the RSRP threshold is set to infinity (or infinitesimal) and all terminals are within the same RSRP range, so the same PUCCH transmission resource set can be determined and then the specific PUCCH transmission resource in the set can be determined according to the DCI indication information.

Optionally, in some embodiments, the at least one PUCCH transmission resource set includes multiple PUCCH transmission resource sets, and all terminal devices corresponding to the first type of traffic each use an independent PUCCH transmission resource. In this case, for example, a corresponding set is determined among a plurality of PUCCH transmission resource sets by RSRP measurement results, and each terminal determines an independent PUCCH transmission resource in the set according to the intra-group ID. For example, a PUCCH transmission resource set is indicated in the DCI indication information, and each terminal determines an independent PUCCH transmission resource in the set based on the intra-group ID. For another example, the terminal determines the PUCCH transmission resource set and the PUCCH transmission resources in the set according to the intra-group ID, as described in detail above with respect to fig. 4 and 5.

Optionally, in some embodiments, the at least one PUCCH transmission resource set includes multiple PUCCH transmission resource sets, and one PUCCH transmission resource is shared between a group of terminal devices corresponding to the first type of service. In this case, the terminal device may determine a target PUCCH transmission resource according to the following modes 4 to 9, where the target PUCCH transmission resource is used to transmit uplink feedback information carrying the first type of service.

Mode 4: and indicating a PUCCH transmission resource set in the DCI, and determining a target PUCCH transmission resource by the terminal according to the RSRP measurement result. That is, the terminal may determine a PUCCH transmission resource set according to the DCI, and configure the RSRP threshold so that terminals having the same RSRP measurement range may share one target PUCCH transmission resource.

Mode 5: and indicating a PUCCH transmission resource set in the DCI, and determining a target PUCCH transmission resource by the terminal according to the intra-group ID. That is, the terminal may determine a PUCCH transmission resource set according to the DCI, determine a target PUCCH transmission resource according to the intra-group ID, and when the number of terminals in multicast communication is greater than the number of PUCCH transmission resources in the set, a plurality of terminals may share one target PUCCH transmission resource.

Mode 6: and the terminal determines a PUCCH transmission resource set according to the RSRP measurement result and determines a target PUCCH transmission resource according to the DCI indication information. That is, by configuring the RSRP threshold, terminals with the same RSRP measurement range use the same PUCCH transmission resource set, and further, the terminals determine the target PUCCH transmission resource according to the indication information in the DCI.

Mode 7: and the terminal determines a PUCCH transmission resource set according to the RSRP measurement result and determines a target PUCCH transmission resource according to the intra-group ID. That is to say, the RSRP threshold is configured so that terminals with the same RSRP measurement range use the same PUCCH transmission resource set, and further, the terminal determines a target PUCCH transmission resource according to the intra-group ID, and when the number of terminals in multicast communication is greater than the number of PUCCH transmission resources in the PUCCH transmission resource set, multiple terminals share one target PUCCH transmission resource.

Mode 8: and the terminal determines a PUCCH transmission resource set according to the intra-group ID and determines a target PUCCH transmission resource according to the RSRP measurement result. That is, the terminal determines a PUCCH transmission resource set, e.g., S, according to the intra-group ID _PUCCH = mod (UE _ ID, N), where N represents the number of PUCCH transmission resource sets, S _PUCCH An index representing the determined PUCCH transmission resource set, mod () representing a modulo operation; further, the terminal determines a target PUCCH transmission resource according to the RSRP measurement result, and terminals having the same RSRP measurement range may share one target PUCCH transmission resource.

Mode 9: and the terminal determines a PUCCH transmission resource set according to the intra-group ID and determines a target PUCCH transmission resource according to the DCI indication information. That is, the terminal determines a PUCCH transmission resource set, e.g., S, according to the intra-group ID _PUCCH = mod (UE _ ID, N), where N represents the number of PUCCH transmission resource sets, S _PUCCH An index representing the determined PUCCH transmission resource set, mod () representing a modulo operation; further, the terminal determines the target PUCCH transmission resource according to the DCI indication information, and the terminal receiving the DCI may determine the same target PUCCH transmission resource.
