[0049] In the NR system, unicast in the Radio Resource Control (RRC) connected state has Hybrid Automatic Repeat reQuest (HARQ) feedback. However, there is no feedback mechanism introduced for multicast and broadcast in other systems, that is, the terminal device does not need to feedback when receiving multicast or broadcast services, and there is no remedy for loss.
[0050] For some services in NR, such as services in scenarios like V2X and industrial Internet, the reliability requirements for multicast and broadcast transmissions are getting higher and higher. Therefore, a feedback mechanism is introduced for multicast and broadcast to ensure the reliability of service transmissions, which is used to ensure that all members within the group have received the service data. Thus, in order to improve the reliability of service transmissions, an uplink feedback mechanism for multicast and broadcast services needs to be introduced so that the network can determine whether to initiate a retransmission based on the feedback information.
[0051] Multimedia Broadcast Multicast Service (MBMS) is a technology that transmits data from one data source to multiple terminal devices by sharing network resources. While providing multimedia services, it can effectively utilize network resources to achieve multimedia service broadcasts and multicasts at a relatively high rate (256 kbps). In addition, the reception of MBMS services is applicable to terminal devices in the RRC connected state (RRC_CONNECTED), RRC idle state (RRC_IDLE), or RRC inactive state (RRC_INACTIVE).
[0052] In order to improve the reliability of MBMS services, a feedback mechanism for MBMS services needs to be introduced, and how to configure the transmission resources of the Physical Uplink Control Channel (PUCCH) to support the feedback mechanism of MBMS services is a problem that needs to be solved.
[0053] Based on the above problems, this application proposes a solution for determining PUCCH transmission resources. For services sent in a multicast or broadcast manner, the terminal device can determine the PUCCH transmission resources for uplink feedback, so that uplink feedback can be performed on services sent in a multicast or broadcast manner to improve the reliability of multicast or broadcast transmissions.
[0054] The technical solution of this application is described in detail below through specific embodiments.
[0055] Figure 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application. As Figure 2 shown, the method 200 may include at least some of the following content:
[0056] S210, the terminal device determines a target PUCCH transmission resource from at least one set of PUCCH transmission resources,
[0057] wherein, the target PUCCH transmission resource is used to transmit uplink feedback information carrying a first type of service, and the uplink feedback information is used to indicate whether the first type of service is correctly received, and the first type of service is sent in a multicast or broadcast manner.
[0058] Optionally, the first type of service is an MBMS service. Of course, the first type of service may also be other services sent in a multicast or broadcast manner, and this application does not limit this.
[0059] In an embodiment of this application, the terminal device receives a Physical Downlink Control Channel (PDCCH) sent by a network device. The PDCCH includes Downlink Control Information (DCI), and the DCI is used to schedule Physical Downlink Shared Channel (PDSCH) resources. The terminal device receives the PDSCH carrying the first type of service sent by the network device on the PDSCH resources scheduled by the DCI. After determining the target PUCCH transmission resource, the terminal device may send a PUCCH to the network device on the target PUCCH transmission resource, and the PUCCH carries uplink feedback information of the first type of service.
[0060] Optionally, the uplink feedback information may be a 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 does not feed back anything. For another example, if the terminal device fails to receive the first type of service, the terminal device feeds back a Negative Acknowledgement (NACK).
[0061] Optionally, in an embodiment of this application, S210 may specifically be:
[0062] The terminal device determines the target PUCCH transmission resource from the at least one PUCCH transmission resource set according to the first information, and / or the terminal device determines a first PUCCH transmission resource set from the at least one PUCCH transmission resource set according to the first information, and the first PUCCH transmission resource set includes the target PUCCH transmission resource;
[0063] Wherein, the first information includes at least one of the following:
[0064] The measurement result of the reference signal received power (RSRP), the radio network temporary identity (RNTI) of the terminal device, the in-group identity within the communication group where the terminal device is located, and the indication information in the DCI for scheduling the PDSCH carrying the first type of service.
[0065] Optionally, the terminal device may determine the target PUCCH transmission resource through the solutions in Examples 1 to 8 below.
[0066] Example 1: The terminal device determines the target PUCCH transmission resource from the at least one PUCCH transmission resource set according to the in-group identity within the communication group where the terminal device is located.
[0067] It should be noted that for multicast communication, usually an independent in-group identity (group member identity) is configured for each terminal, that is, the in-group identity within the communication group where the terminal device is located. When the network device configures the PUCCH transmission resource set for the terminal device, the terminal device can determine the corresponding PUCCH transmission resource from the PUCCH transmission resource set according to its in-group identity within the communication group, so that each in-group terminal can have an independent PUCCH transmission resource.
[0068] For example, a communication group includes 4 terminal devices, and the in-group identities (IDs) assigned by the network device are UEID#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. When the network device sends a multicast PDSCH, each terminal device determines the corresponding PUCCH transmission resource in the PUCCH transmission resource set according to its respective in-group identity (ID). For example, R PUCCH = mod(UE_ID, M), where M represents the number of PUCCH transmission resources in the PUCCH transmission resource set, and R PUCCH represents the index of the determined target PUCCH transmission resource, and mod() represents the modulo operation. As Figure 3 shown, 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.
[0069] For another example, number the PUCCH resources in all PUCCH transmission resource sets. The terminal device determines the corresponding PUCCH transmission resource set and the specific target PUCCH transmission resource according to the in-group identifier within its communication group. As Figure 4 shown, assume that the at least one PUCCH transmission resource set includes two PUCCH transmission resource sets, 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, PUCCH transmission resource set 1 includes 4 PUCCH transmission resources. Number them uniformly, that is, the index of the PUCCH transmission resource is [0, 11]. The terminal device determines the corresponding PUCCH transmission resource according to the in-group identifier within its communication group. For example, R PUCCH = mod(UE_ID, M), where M represents the number of PUCCH transmission resources in all PUCCH transmission resource sets, R PUCCH represents the index of the determined target PUCCH transmission resource, and mod() represents the modulo operation. Where M = 12, that is, the total number of all PUCCH transmission resources. When UE_ID = 1, the index of the determined target PUCCH transmission resource is 1, which is the second PUCCH transmission resource in PUCCH transmission resource set 0; when UE_ID = 10, the index of the determined target PUCCH transmission resource is 10, which is the third PUCCH transmission resource in PUCCH transmission resource set 1.
[0070] For another example, as Figure 5 shown, assume that the at least one PUCCH transmission resource set includes two PUCCH transmission resource sets, 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, the index of the PUCCH transmission resource is [0, 7], PUCCH transmission resource set 1 includes 4 PUCCH transmission resources, the index of the PUCCH transmission resource is [0, 3]. The terminal device first determines the PUCCH transmission resource set according to the in-group identifier within its communication group. For example, S PUCCH = mod(UE_ID, N), where N represents the number of PUCCH transmission resource sets, which is 2, S PUCCH represents the index of the determined PUCCH transmission resource set, and mod() represents the modulo operation. Further, the terminal device determines the PUCCH transmission resource according to the in-group identifier within its communication group. R PUCCH = mod(UE_ID, M), where M represents the number of PUCCH transmission resources included in the PUCCH transmission resource set, R PUCCHIndicates the index of the determined target PUCCH transmission resource, and mod() represents the modulo operation. For PUCCH transmission resource set 0, M = 8; for PUCCH transmission resource set 1, M = 4. When UE_ID = 1, the index of the determined PUCCH transmission resource set is 1, i.e., the second PUCCH transmission resource set, and the index of the determined target PUCCH transmission resource is 1, i.e., the second PUCCH transmission resource in 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.
[0071] Optionally, in Example 1, when the terminal device determines multiple PUCCH transmission resources from the at least one PUCCH transmission resource set according to the in-group identifier within the communication group where the terminal device is located, the terminal device determines the first PUCCH transmission resource among the multiple PUCCH transmission resources as the target PUCCH transmission resource, or the terminal device determines a randomly selected PUCCH transmission resource among the multiple PUCCH transmission resources as the target PUCCH transmission resource.
[0072] Example 2, the terminal device determines the first PUCCH transmission resource set from the at least one PUCCH transmission resource set according to the in-group identifier within the communication group where the terminal device is located; and the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to at least one of the RSRP measurement result, the RNTI of the terminal device, and the indication information in the DCI for scheduling the PDSCH carrying the first type of service.
[0073] Optionally, in Example 2, when the number of the at least one PUCCH transmission resource set 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 in-group identifier within the communication group where the terminal device is located. For example, S PUCCH = mod(UE_ID, N), where N represents the number of PUCCH transmission resource sets, and S PUCCH represents the index of the determined PUCCH transmission resource set, i.e., the index of the first PUCCH transmission resource set, and mod() represents the modulo operation.
[0074] In Example 2, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to the RSRP measurement result. Assuming that the first PUCCH transmission resource set includes 3 PUCCH transmission resources, where 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.
[0075] For example, Figure 6 As shown, the network device configures three RSRP thresholds, which are respectively recorded as RSRP-THD1, RSRP-THD2, and RSRP-THD3, and configures four PUCCH transmission resources, which are respectively recorded as PUCCH transmission resource #0, PUCCH transmission resource #1, PUCCH transmission resource #2, and PUCCH transmission resource #3. Different RSRP ranges correspond to different PUCCH resources. Multiple PUCCH transmission resources can be frequency-division multiplexing (FDM), time-division multiplexing (TDM), or code division multiplexing (CDM). The terminal device receives the MBMS data sent by the network device, and according to the downlink signal (such as synchronization signal block / physical broadcast channel block (SS / PBCH), Channel State Information Reference Signal (CSI) The terminal measures the downlink RSRP of the mobile station using the RSRP range and the corresponding PUCCH transmission resource according to the currently measured RSRP. If the terminal does not correctly receive the MBMS data, a NACK is sent on the corresponding PUCCH transmission resource, otherwise no feedback information is sent. In one embodiment, the network device configures the correspondence between the RSRP range and the PUCCH resource.
[0076] In Example 2, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to the RNTI of the terminal device. PUCCH= mod(UE_RNTI, M), where UE_RNTI represents the RNTI of the terminal device, M represents the number of PUCCH transmission resources in the first PUCCH transmission resource set, and R PUCCH represents the index of the determined target PUCCH transmission resource, and mod() represents the modulo operation.
[0077] In Example 2, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to the indication information in the DCI for scheduling the PDSCH carrying the first type of service. For example, if the indication information is the index of the target PUCCH transmission resource, the terminal device can determine the target PUCCH transmission resource according to the indication information.
[0078] Example 3, the terminal device determines the target PUCCH transmission resource from the at least one PUCCH transmission resource set according to the RNTI of the terminal device. For example, R PUCCH = mod(UE_RNTI, M), where UE_RNTI represents the RNTI of the terminal device, M represents the number of PUCCH transmission resources in the PUCCH transmission resource set, and R PUCCH represents the index of the determined target PUCCH transmission resource, and mod() represents the modulo operation.
[0079] Example 4, the terminal device determines the first PUCCH transmission resource set from the at least one PUCCH transmission resource set according to the RNTI of the terminal device; and the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to at least one of the RSRP measurement result, the group identity within the communication group where the terminal device is located, and the indication information in the DCI for scheduling the PDSCH carrying the first type of service.
[0080] Optionally, in Example 4, when the number of the at least one PUCCH transmission resource set is greater than 1, the terminal device can 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 the RNTI of the terminal device, N represents the number of PUCCH transmission resource sets, and S PUCCH represents the index of the determined PUCCH transmission resource set, that is, the index of the first PUCCH transmission resource set, and mod() represents the modulo operation.
[0081] In Example 4, for example, the terminal device determines the target PUCCH transmission resource from the first set of PUCCH transmission resources according to the RSRP measurement result. Suppose the first set of PUCCH transmission resources includes 4 PUCCH transmission resources. Among them, PUCCH transmission resource #0 corresponds to the RSRP range 0, PUCCH transmission resource #1 corresponds to the RSRP range 1, PUCCH transmission resource #2 corresponds to the RSRP range 2, and PUCCH transmission resource #3 corresponds to the RSRP range 3. In this case, suppose the RSRP measurement result measured by the terminal device belongs to the RSRP range 2, then the target PUCCH transmission resource is PUCCH transmission resource #2.
[0082] In Example 4, for example, the terminal device determines the target PUCCH transmission resource from the first set of PUCCH transmission resources according to the group identification within the communication group where the terminal device is located. For example, R PUCCH = mod(UE_ID, M), where UE_ID represents the group identification within the communication group where the terminal device is located, M represents the number of PUCCH transmission resources in the first set of PUCCH transmission resources, and R PUCCH represents the index of the determined target PUCCH transmission resource, and mod() represents the modulo operation.
[0083] In Example 4, for example, the terminal device determines the target PUCCH transmission resource from the first set of PUCCH transmission resources according to the indication information in the DCI for scheduling the PDSCH carrying the first type of service. For example, if the indication information is the index of the target PUCCH transmission resource, the terminal device can determine the target PUCCH transmission resource according to the indication information.
[0084] In Example 5, the terminal device determines the target PUCCH transmission resource from the at least one set of PUCCH transmission resources according to the RSRP measurement result.
[0085] Optionally, in Example 5, the terminal device determines the target PUCCH transmission resource from the at least one set of PUCCH transmission resources according to the RSRP measurement result, at least one RSRP threshold, and the first correspondence relationship, where the first correspondence relationship is the correspondence relationship between the RSRP range and the PUCCH transmission resource.
[0086] It should be noted that the at least one RSRP threshold is used to determine the RSRP range.
[0087] 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. Assume that the PUCCH transmission resource set includes 3 PUCCH transmission resources, where 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, assume that the RSRP measurement result measured by the terminal device belongs to RSRP range 1, then the target PUCCH transmission resource is PUCCH transmission resource #1.
[0088] Optionally, the at least one RSRP threshold is pre-configured or agreed upon by the protocol, or the at least one RSRP threshold is configured by the network device.
[0089] Optionally, the first correspondence is pre-configured or agreed upon by the protocol, or the first correspondence is configured by the network device.
[0090] Example 6, the terminal device determines a first PUCCH transmission resource set from the at least one PUCCH transmission resource set according to the RSRP measurement result; and the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to at least one of the group identity within the communication group where the terminal device is located, the RNTI of the terminal device, and the indication information in the DCI for scheduling the PDSCH carrying the first type of service.
[0091] In Example 6, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to the group identity within the communication group where the terminal device is located. For example, R PUCCH = mod(UE_ID, M), where UE_ID represents the group identity within the communication group where the terminal device is located, M represents the number of PUCCH transmission resources in the first PUCCH transmission resource set, R PUCCH represents the index of the determined target PUCCH transmission resource, and mod() represents the modulo operation.
[0092] In Example 6, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to the RNTI of the terminal device. For example, R PUCCH = mod(UE_RNTI, M), where UE_RNTI represents the RNTI of the terminal device, M represents the number of PUCCH transmission resources in the first PUCCH transmission resource set, R PUCCH represents the index of the determined target PUCCH transmission resource, and mod() represents the modulo operation.
[0093] In Example 6, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to the indication information in the DCI for scheduling the PDSCH carrying the first type of service. For example, if the indication information is the index of the target PUCCH transmission resource, the terminal device can determine the target PUCCH transmission resource according to the indication information.
[0094] Example 7, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to the indication information in the DCI for scheduling the PDSCH carrying the first type of service; or,
[0095] The terminal device determines a first PUCCH transmission resource set from the first PUCCH transmission resource set according to the indication information in the DCI for scheduling the PDSCH carrying the first type of service, and the first PUCCH transmission resource set includes the target PUCCH transmission resource.
[0096] Example 8, the terminal device determines a first PUCCH transmission resource set from the at least one PUCCH transmission resource set according to the indication information in the DCI for scheduling the PDSCH carrying the first type of service; and the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to at least one of the RSRP measurement result, the group identity within the communication group where the terminal device is located, and the RNTI of the terminal device.
[0097] In Example 8, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to the RSRP measurement result. Suppose the first PUCCH transmission resource set includes 4 PUCCH transmission resources. Among them, PUCCH transmission resource #0 corresponds to the RSRP range 0, PUCCH transmission resource #1 corresponds to the RSRP range 1, PUCCH transmission resource #2 corresponds to the RSRP range 2, and PUCCH transmission resource #3 corresponds to the RSRP range 3. In this case, assuming that the measured RSRP measurement result of the terminal device belongs to the RSRP range 2, the target PUCCH transmission resource is PUCCH transmission resource #2.
[0098] In Example 8, for example, the terminal device determines the target PUCCH transmission resource from the first PUCCH transmission resource set according to the group identity within the communication group where the terminal device is located. For example, R PUCCH = mod(UE_ID,M), where UE_ID represents the group identity within the communication group where the terminal device is located, M represents the number of PUCCH transmission resources in the first PUCCH transmission resource set, RPUCCH represents the index of the determined target PUCCH transmission resource, and mod() represents the modulo operation.
[0099] In Example 8, for example, the terminal device determines the target PUCCH transmission resource from the first set of PUCCH transmission resources according to the RNTI of the terminal device. For example, R PUCCH = mod(UE_RNTI, M), where UE_RNTI represents the RNTI of the terminal device, M represents the number of PUCCH transmission resources in the first set of PUCCH transmission resources, and R PUCCH represents the index of the determined target PUCCH transmission resource, and mod() represents the modulo operation.
[0100] Optionally, in the embodiments of the present application, the RNTI of the terminal device includes at least one of the following:
[0101] Cell RNTI (Cell-RNTI, C-RNTI), Multicast RNTI (Group-RNTI, G-RNTI), Broadcast RNTI (Broadcast-RNTI, B-RNTI).
[0102] Optionally, in some embodiments, the at least one set of PUCCH transmission resources is configured by the network device through common signaling or user-specific signaling.
[0103] Optionally, when the at least one set of PUCCH transmission resources is configured by the network device through user-specific signaling, the network device configures the same set of PUCCH transmission resources for the terminal devices corresponding to the first type of service.
[0104] Optionally, the common signaling includes at least one of the following:
[0105] System Information Block (SIB) information, cell-specific RRC signaling.
[0106] Optionally, in some embodiments, the at least one set of PUCCH transmission resources includes only one set of PUCCH transmission resources, and the same PUCCH transmission resources are shared among all terminal devices corresponding to the first type of service.
[0107] It should be noted that assuming the first type of service is the MBMS service, the PUCCH transmission resources are shared among the terminals of MBMS, that is, multiple terminals use the same PUCCH transmission resources. Therefore, multiple terminals will determine the same PUCCH transmission resources. In this case, for example, the target PUCCH transmission resources can be determined by the following Method 1 to Method 3, and the target PUCCH transmission resources are used to transmit the uplink feedback information carrying the MBMS service.
[0108] Method 1: Indicate the specific target PUCCH transmission resources in the DCI scheduling the PDSCH carrying MBMS.
[0109] Method 2: Configure only one PUCCH transmission resource for the MBMS service.
[0110] Method 3: The RSRP threshold is set to infinitesimal (or infinite). At this time, the RSRP results measured by all UEs are within the same RSRP range. Therefore, the same PUCCH transmission resources can be determined.
[0111] Optionally, in some embodiments, the at least one set of PUCCH transmission resources includes only one set of PUCCH transmission resources, and all terminal devices corresponding to the first type of service each use independent PUCCH transmission resources.
[0112] It should be noted that in order to enable the terminals to use independent PUCCH transmission resources, the terminals need to be able to determine independent PUCCH transmission resources from the set of PUCCH transmission resources according to parameters. Since the DCI scheduling the PDSCH is sent to a group of terminals, it is impossible to indicate the PUCCH transmission resources of each terminal through the DCI. Specifically, for example, the terminal can determine the corresponding PUCCH transmission resources in the set of PUCCH transmission resources according to the in-group ID. Since the in-group ID of each terminal is different, independent PUCCH transmission resources can be determined.
[0113] Optionally, in some embodiments, the at least one PUCCH transmission resource set includes only one PUCCH transmission resource set, and a PUCCH transmission resource is shared among a group of terminal devices corresponding to the first type of service. In this case, for example, a terminal device can determine the PUCCH transmission resource according to the in-group ID. When the number of PUCCH transmission resources configured by the network device is less than the number of terminal devices in the communication group, multiple terminals will share a PUCCH transmission resource. For example, the network device configures a PUCCH transmission resource set, and the PUCCH transmission resource set includes 4 PUCCH transmission resources, but the receiving terminals for multicast communication include 12 terminals. In this case, multiple terminals will share a PUCCH transmission resource. When a terminal determines the PUCCH transmission resource according to the in-group ID, such as R PUCCH = mod(UE_ID, M), where M represents the number of PUCCH transmission resources, the value range of UE_ID is [0, 11], mod() represents the modulo operation. According to the calculation, it is known that the terminals with UE_ID of 0, 4, and 8 share a PUCCH transmission resource. Similarly, the terminals with UE_ID of 1, 5, and 9 share a PUCCH transmission resource; the terminals with UE_ID of 2, 6, and 10, and the terminals with UE_ID of 3, 7, and 11 share the other two PUCCH transmission resources.
[0114] For multicast and broadcast services, the data sent by the network device needs to be received by multiple terminals, and these multiple terminals may be located at different positions in the cell. For Frequency Range 2 (FR2), its corresponding frequency is usually high frequency, such as 24.25 GHz - 52.6 GHz. To ensure the coverage range, the network device usually uses beamforming to send data. To ensure that all terminal devices can receive MBMS data, the network device usually sends the MBMS data once using all the beams. The network sends data using different beams at different times, so that terminals located at different positions in the cell may correctly receive the data. In the DCI sent using different beams, a PUCCH resource is indicated. The user who receives the DCI uses the PUCCH resource indicated by the DCI for feedback. As Figure 7 shown, the network device (gNB) sends MBMS data in turn through 4 beams at 4 times (time 1, time 2, time 3, and time 4), Figure 7The ellipses shown respectively correspond to beam 0, beam 1, beam 2, and beam 3 from left to right. The terminal device detects MBMS data on each beam respectively. If the detection is successful in at least one direction, it can be considered that the MBMS data detection is successful. If the detection is not successful in all directions, it is considered that the MBMS detection fails. The network device configures the PUCCH resources for the terminal device to send uplink feedback information. Figure 7 The 4 beams in Figure 8 correspond to 4 PUCCH transmission resources in . Each PUCCH transmission resource includes a PUCCH-ACK resource and a PUCCH-NACK resource. The PUCCH-ACK resource is used for the terminal device to send an acknowledgement (ACK) message to the network, and the PUCCH-NACK resource is used for the terminal device to send a negative acknowledgement (NACK) message to the network. The PUCCH resources are after all the time-domain resources used to transmit the MBMS data, so that the terminal device can determine whether the detection is successful according to the detection results of the MBMS data sent in all directions.
[0115] Optionally, in some embodiments, the at least one set of PUCCH transmission resources includes multiple sets of PUCCH transmission resources, and the same PUCCH transmission resources are shared among all the terminal devices corresponding to the first type of service. In this case, in order to enable multiple terminals to share the same PUCCH transmission resources, it is first necessary to select the same set of PUCCH transmission resources. For example, the set of PUCCH transmission resources is indicated in the DCI, and the PUCCH transmission resource index is also indicated; all the terminals that receive the DCI determine the corresponding set of transmission resources according to the indication information, and determine the transmission resources in the set of transmission resources. Another example is that the DCI indicates the set of PUCCH transmission resources, and the PUCCH transmission resources are determined through the RSRP measurement results; the terminal determines the specific set of PUCCH transmission resources according to the DCI indication information, determines the specific PUCCH transmission resources in the set according to the RSRP measurement results, and sets the RSRP threshold to infinity (or negative infinity). All the terminals are within the same RSRP range, so the same PUCCH transmission resources can be determined. Still another example is that the set of PUCCH transmission resources is determined according to the RSRP measurement results, and the PUCCH transmission resources are indicated through the DCI: the RSRP threshold is set to infinity (or negative infinity), all the terminals are within the same RSRP range, so the same set of PUCCH transmission resources can be determined, and then the specific PUCCH transmission resources in the set are determined according to the DCI indication information.
[0116] Optionally, in some embodiments, the at least one PUCCH transmission resource set includes a plurality of PUCCH transmission resource sets, and all terminal devices corresponding to the first type of service each use an independent PUCCH transmission resource. In this case, for example, the corresponding set is determined from the plurality of PUCCH transmission resource sets based on the RSRP measurement result, and each terminal determines an independent PUCCH transmission resource in the set according to the in-group ID. Another example is that the PUCCH transmission resource set is indicated in the DCI, and each terminal determines an independent PUCCH transmission resource in the set according to the in-group ID. Still another example is that the terminal determines the PUCCH transmission resource set and the PUCCH transmission resource in the set according to the in-group ID. For details, see the above description about Figure 4 and Figure 5 description.
[0117] Optionally, in some embodiments, the at least one PUCCH transmission resource set includes a plurality of PUCCH transmission resource sets, and a group of terminal devices corresponding to the first type of service share a PUCCH transmission resource. In this case, the terminal device may determine the target PUCCH transmission resource according to the following methods 4 to 9. The target PUCCH transmission resource is used to transmit the uplink feedback information carrying the first type of service.
[0118] Method 4: The PUCCH transmission resource set is indicated in the DCI, and the terminal determines the target PUCCH transmission resource according to the RSRP measurement result. That is to say, the terminal can determine the PUCCH transmission resource set according to the DCI, and by configuring the RSRP threshold, terminals with the same RSRP measurement range can share a target PUCCH transmission resource.
[0119] Method 5: The PUCCH transmission resource set is indicated in the DCI, and the terminal determines the target PUCCH transmission resource according to the in-group ID. That is to say, the terminal can determine the PUCCH transmission resource set according to the DCI and determine the target PUCCH transmission resource according to the in-group ID. When the number of terminals in the multicast communication is greater than the number of PUCCH transmission resources in the set, multiple terminals will share a target PUCCH transmission resource.
[0120] Method 6: The terminal determines the PUCCH transmission resource set according to the RSRP measurement result and determines the target PUCCH transmission resource according to the DCI indication information. That is to say, by configuring the RSRP threshold, terminals with the same RSRP measurement range use the same PUCCH transmission resource set. Further, the terminal determines the target PUCCH transmission resource according to the indication information in the DCI.
[0121] Method 7: The terminal determines the PUCCH transmission resource set according to the RSRP measurement result, and determines the target PUCCH transmission resource according to the in-group ID. That is to say, by configuring the RSRP threshold, terminals with the same RSRP measurement range use the same PUCCH transmission resource set. Further, the terminal determines the target PUCCH transmission resource according to the in-group ID. When the number of terminals in the multicast communication is greater than the number of PUCCH transmission resources in the PUCCH transmission resource set, multiple terminals will share a target PUCCH transmission resource.
[0122] Method 8: The terminal determines the PUCCH transmission resource set according to the in-group ID, and determines the target PUCCH transmission resource according to the RSRP measurement result. That is to say, the terminal determines the PUCCH transmission resource set according to the in-group ID, such as S PUCCH = mod(UE_ID, N), where N represents the number of PUCCH transmission resource sets, and S PUCCH represents the index of the determined PUCCH transmission resource set, and mod() represents the modulo operation; further, the terminal determines the target PUCCH transmission resource according to the RSRP measurement result, and terminals with the same RSRP measurement range can share a target PUCCH transmission resource.
[0123] Method 9: The terminal determines the PUCCH transmission resource set according to the in-group ID, and determines the target PUCCH transmission resource according to the DCI indication information. That is to say, the terminal determines the PUCCH transmission resource set according to the in-group ID, such as S PUCCH = mod(UE_ID, N), where N represents the number of PUCCH transmission resource sets, and S PUCCH represents the index of the determined PUCCH transmission resource set, and mod() represents the modulo operation; further, the terminal determines the target PUCCH transmission resource according to the DCI indication information, and the terminals receiving the DCI can determine the same target PUCCH transmission resource.
[0124] Therefore, in the embodiments of the present application, the terminal device determines the target PUCCH transmission resource for transmitting the uplink feedback information carrying the first type of service from at least one PUCCH transmission resource set, so that the uplink feedback can be performed for the first type of service on the target PUCCH transmission resource, thereby improving the transmission reliability of the first type of service sent in a multicast or broadcast manner.
