[0019] It should be noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA), and other systems.

[0020] 1 is a block diagram of a wireless communication system to which the embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be a terminal device such as a mobile phone, a tablet personal computer, a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, a vehicle-mounted equipment (VUE), a pedestrian terminal (PUE), a smart home (home equipment having a wireless communication function, such as a refrigerator, a television, a washing machine, or furniture), a game console, a personal computer (PC), a deposit machine, or a self-service machine, and the wearable device includes a smart watch, a smart wristband, a smart earphone, a smart glasses, a smart accessory (a smart bracelet, a smart hand chain, a smart ring, a smart necklace, a smart ankle bracelet, a smart anklet, etc.), a smart band, a smart clothing, etc. It should be noted that the terminal 11 in the embodiment of the present application is not limited to a specific type. The network side equipment 12 may include an access network equipment or a core network equipment, where the access network equipment 12 may be called a radio access network equipment, a radio access network (Radio Access Network, RAN), a radio access network function or a radio access network unit.The access network equipment 12 may include a base station, a WLAN access point, or a WiFi node, and the base station may be called a Node B, an evolved Node B (eNB), an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a home B node, a home evolved B node, a transmitting receiving point (TRP), or any other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to a specific technical term, and it should be explained that in the embodiments of the present application, only base stations in an NR system are introduced as examples, and the specific type of the base station is not limited.

[0021] First, after the base station transmits a Physical Downlink Shared Channel (PDSCH) / or a Physical Downlink Control Channel (PDCCH) (such as a PDCCH instructing a semi-static PDSCH release), the terminal needs to feed back the PDSCH / PDCCH decoding result to the base station after completing reception and decoding, inform the base station whether the PDSCH / semi-static PDSCH decoding is successful, and release the PDCCH. The base station makes a scheduling decision for the next step based on the feedback, and this process is called Hybrid Automatic Repeat request (HARQ).

[0022] In the HARQ-ACK / NACK feedback mode, if the terminal successfully decodes the PDSCH / PDCCH, an ACK is fed back, otherwise a NACK is fed back. In the HARQ NACK only feedback mode, if the terminal subsequently does not successfully decode the PDSCH / PDCCH, a NACK is fed back, otherwise no information is fed back.

[0023] In the following, the hybrid automatic repeat request response feedback method according to the embodiments of the present application will be described in detail through several embodiments and its application scenarios in conjunction with the drawings.

[0024] 2 is a flow chart of a hybrid automatic repeat request response feedback method according to an embodiment of the present application. As shown in FIG. 2, the hybrid automatic repeat request response feedback method according to the embodiment includes the following steps:

[0025] Step 201: when the first channel resource of the unicast HARQ-ACK is not configured in the terminal, the terminal feeds back a unicast HARQ-ACK and a multicast HARQ-ACK to the network side device through a target channel resource of the multicast HARQ-ACK, or feeds back a multicast HARQ-ACK; or When the first channel resource of the unicast HARQ-ACK is not configured in the terminal, the terminal feeds back the unicast HARQ-ACK and the multicast HARQ-ACK to the network side device through the second channel resource of the unicast HARQ-ACK, or feeds back the unicast HARQ-ACK; Here, the unicast HARQ-ACK and the multicast HARQ-ACK have the same priority and are fed back in the same time unit, and the first channel resource and the second channel resource are configured based on different configuration parameters.

[0026] Specifically, the first channel resource and the second channel resource of the unicast HARQ-ACK are configured based on different configuration parameters. For example, the first channel resource of the unicast HARQ-ACK may be a PUCCH resource in the PUCCH resource list configured by the configuration parameter SPS-PUCCH-AN-List, and the second channel resource of the unicast HARQ-ACK may be a PUCCH resource configured by the configuration parameter n1PUCCH-AN.

[0027] Alternatively, the target channel resource of the multicast HARQ-ACK may include a third channel resource corresponding to the multicast dynamic HARQ-ACK, a fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK, and a fifth channel resource. The third channel resource, the fourth channel resource, or the fifth channel resource is configured based on different configuration parameters. For example, the third channel resource corresponding to the multicast dynamic HARQ-ACK may be a PUCCH resource in the PUCCH resource list configured by the configuration parameter pucch-ConfigurationList-Multicast1 or pucch-ConfigurationList-Multicast2, the fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK may be a PUCCH resource in the PUCCH resource list configured by the configuration parameter SPS-PUCCH-AN-List-Multicast, and the fifth channel resource may be a PUCCH resource configured by the configuration parameter n1PUCCH-AN.

[0028] Alternatively, when the multicast HARQ-ACK includes a HARQ-ACK whose feedback mode is ACK / NACK mode, a third channel resource corresponding to the multicast dynamic HARQ-ACK is adopted, where the third channel resource may be a PUCCH resource in a PUCCH resource list configured by the configuration parameter pucch-ConfigurationList-Multicast1, and the configured PUCCH resource may be terminal-specific because the feedback mode is ACK / NACK mode. When the feedback mode of the multicast HARQ-ACK is NACK only, a third channel resource corresponding to the multicast dynamic HARQ-ACK is adopted, where the third channel resource may be a PUCCH resource in a PUCCH resource list configured by the configuration parameter pucch-ConfigurationList-Multicast2.

[0029] The time unit may be a slot, a subslot, a subframe, a frame, an OFDM symbol set, and so on.

[0030] When the network side device schedules to feed back unicast HARQ-ACK and multicast HARQ-ACK having the same priority in the same time unit, it is optional to configure the first channel resource of unicast HARQ-ACK in the terminal, so if the first channel resource of unicast HARQ-ACK is not configured in the terminal, the unicast HARQ-ACK and / or multicast HARQ-ACK cannot be fed back to the network side device through the first channel resource of unicast HARQ-ACK. In this step, when the first channel resource of unicast HARQ-ACK is not configured in the terminal, the terminal can feed back unicast HARQ-ACK and multicast HARQ-ACK to the network side device through the target channel resource of multicast HARQ-ACK, or feed back multicast HARQ-ACK, or the terminal can feed back unicast HARQ-ACK and multicast HARQ-ACK to the network side device through the second channel resource of unicast HARQ-ACK.

[0031] In this embodiment, when a network side device schedules a unicast HARQ-ACK and a multicast HARQ-ACK having the same priority to be fed back in the same time unit, and a first channel resource for a unicast HARQ-ACK is not configured in a terminal, the embodiment can select various different feedback methods to feed back a unicast HARQ-ACK and / or a multicast HARQ-ACK, thereby realizing the feedback of a HARQ-ACK, improving communication reliability, and providing relatively greater flexibility.

[0032] In one embodiment, in the above step 201, the terminal feeding back the unicast HARQ-ACK and the multicast HARQ-ACK to the network side device via the second channel resource of the unicast HARQ-ACK includes, when the total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK is equal to or less than a predetermined number of bits, the terminal multiplexing the unicast HARQ-ACK and the multicast HARQ-ACK onto the second channel resource of the unicast HARQ-ACK and feeding it back to the network side device.

[0033] Specifically, the preset number of bits may be 2 bits. For example, when the second channel resource of the unicast HARQ-ACK can transmit up to 2 bits, if the total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK is equal to 2 bits, the terminal can adopt a feedback method in which the unicast HARQ-ACK and the multicast HARQ-ACK are multiplexed onto the second channel resource of the unicast HARQ-ACK and fed back to the network side device.

[0034] In this embodiment, when the network side device schedules so that unicast HARQ-ACK and multicast HARQ-ACK having the same priority are fed back in the same time unit, and the first channel resource of the unicast HARQ-ACK is not configured in the terminal, if the total number of bits of the unicast HARQ-ACK and multicast HARQ-ACK is less than or equal to a predetermined number of bits, the terminal can adopt a feedback method in which the unicast HARQ-ACK and multicast HARQ-ACK are multiplexed on the second channel resource of the unicast HARQ-ACK and fed back to the network side device, thereby realizing feedback of the HARQ-ACK and improving the reliability of communication.

[0035] Selectively, when the total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK is equal to or less than a preset number of bits, the terminal multiplexes the unicast HARQ-ACK and the multicast HARQ-ACK onto the second channel resource of the unicast HARQ-ACK and feeds it back to the network side device includes, when a third channel resource corresponding to the multicast dynamic HARQ-ACK and / or a fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK is not configured in the terminal and the total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK is equal to or less than a preset number of bits, the terminal multiplexes the unicast HARQ-ACK and the multicast HARQ-ACK onto the second channel resource of the unicast HARQ-ACK and feeds it back to the network side device.

[0036] Specifically, since the terminal is not configured with the third channel resource corresponding to the multicast dynamic HARQ-ACK and / or the fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK, the terminal cannot multiplex the unicast HARQ-ACK and the multicast HARQ-ACK on the third channel resource or the fourth channel resource and feed back to the network side device. In this case, the preset bit number may be 2 bits, and if the total bit number of the unicast HARQ-ACK and the multicast HARQ-ACK is equal to 2 bits, the terminal can multiplex the unicast HARQ-ACK and the multicast HARQ-ACK on the second channel resource of the unicast HARQ-ACK and feed back to the network side device.

[0037] In this embodiment, when the network side device schedules unicast HARQ-ACK and multicast HARQ-ACK having the same priority to be fed back in the same time unit, and the first channel resource of the unicast HARQ-ACK is not configured in the terminal, and the third channel resource corresponding to the multicast dynamic HARQ-ACK and / or the fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK is not configured in the terminal, if the total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK is less than or equal to a preset number of bits, the terminal can adopt a feedback method of multiplexing the unicast HARQ-ACK and the multicast HARQ-ACK on the second channel resource of the unicast HARQ-ACK and feeding it back to the network side device, thereby realizing the feedback of the HARQ-ACK and improving the reliability of communication.

[0038] In one embodiment, the terminal feeding back the unicast HARQ-ACK to the network side device via the second channel resource of the unicast HARQ-ACK in the above step 201 includes the terminal discarding the multicast HARQ-ACK and feeding back the unicast HARQ-ACK to the network side device via the second channel resource of the unicast HARQ-ACK in at least one of the following cases: 1. a third channel resource corresponding to a multicast dynamic HARQ-ACK and / or a fourth channel resource corresponding to a multicast semi-static scheduling HARQ-ACK is not configured in the terminal; 2. a total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than a preset number of bits; and 3. the number of bits of the unicast HARQ-ACK is equal to or greater than the number of bits of the multicast HARQ-ACK.

[0039] Specifically, in the above case 1, since the third channel resource corresponding to the multicast dynamic HARQ-ACK and / or the fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK is not configured in the terminal, the terminal cannot multiplex the unicast HARQ-ACK and the multicast HARQ-ACK on the third channel resource or the fourth channel resource and feed it back to the network side device. In such a case, a feedback method can be selected in which the multicast HARQ-ACK is discarded and the unicast HARQ-ACK is fed back to the network side device via the second channel resource of the unicast HARQ-ACK.

[0040] In the above case 2, the preset number of bits may be 2 bits, and since the total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than 2 bits, assuming that the second channel resource of the unicast HARQ-ACK can transmit up to 2 bits, in such a case, a feedback method can be selected in which the multicast HARQ-ACK is discarded and the unicast HARQ-ACK is fed back to the network side device via the second channel resource of the unicast HARQ-ACK.

[0041] In the above case 3, the number of bits of the unicast HARQ-ACK is equal to or greater than the number of bits of the multicast HARQ-ACK, and a feedback method can be selected in which the multicast HARQ-ACK with a relatively small number of bits is discarded and the unicast HARQ-ACK is fed back to the network side device via the second channel resource of the unicast HARQ-ACK.

[0042] In this embodiment, when the network side device schedules so that unicast HARQ-ACK and multicast HARQ-ACK having the same priority are fed back in the same time units, and if the first channel resource of the unicast HARQ-ACK is not configured in the terminal, a feedback method can be selected in at least one of the above cases to discard the multicast HARQ-ACK and feed back the unicast HARQ-ACK to the network side device via the second channel resource of the unicast HARQ-ACK, thereby realizing feedback of the HARQ-ACK and improving the reliability of communication.

[0043] In one embodiment, in the above step 201, the terminal feeds back the unicast HARQ-ACK and the multicast HARQ-ACK to the network side device via the target channel resource of the multicast HARQ-ACK, including the terminal multiplexing the unicast HARQ-ACK and the multicast HARQ-ACK onto the target channel resource of the multicast HARQ-ACK and feeding it back to the network side device, and the target channel resource is determined based on the total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK.

[0044] Specifically, the target channel resource is determined from the resource list configured according to the total number of bits of unicast HARQ-ACK and multicast HARQ-ACK. In this embodiment, when the network side device schedules the unicast HARQ-ACK and multicast HARQ-ACK with the same priority to be fed back in the same time unit, and the first channel resource of unicast HARQ-ACK is not configured in the terminal, the terminal can also adopt the feedback method of multiplexing the unicast HARQ-ACK and multicast HARQ-ACK on the target channel resource of multicast HARQ-ACK and feeding back to the network side device, and realizes the feedback of HARQ-ACK, and improves the reliability of communication.

[0045] Alternatively, the terminal multiplexing the unicast HARQ-ACK and the multicast HARQ-ACK onto the target channel resource of the multicast HARQ-ACK and feeding it back to the network side device includes, when the total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than a predetermined number of bits, the terminal multiplexing the unicast HARQ-ACK and the multicast HARQ-ACK onto the target channel resource of the multicast HARQ-ACK and feeding it back to the network side device.

[0046] Specifically, the preset bit number may be 2 bits, and the total bit number of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than 2 bits, and the unicast HARQ-ACK cannot be transmitted through the second channel resource. The terminal can also multiplex the unicast HARQ-ACK and the multicast HARQ-ACK onto the target channel resource of the multicast HARQ-ACK and feed it back to the network side device.

[0047] In this embodiment, when the network side device schedules unicast HARQ-ACK and multicast HARQ-ACK having the same priority to be fed back in the same time unit, and the first channel resource of the unicast HARQ-ACK is not configured in the terminal, if the total number of bits of the unicast HARQ-ACK and multicast HARQ-ACK is greater than a preset number of bits, the terminal can adopt a feedback method in which the unicast HARQ-ACK and multicast HARQ-ACK are multiplexed on the target channel resource of the multicast HARQ-ACK and fed back to the network side device, thereby realizing the feedback of HARQ-ACK and improving the reliability of communication.

[0048] Alternatively, the target channel resource includes a third channel resource corresponding to the multicast dynamic HARQ-ACK and / or a fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK, and the terminal multiplexing the unicast HARQ-ACK and the multicast HARQ-ACK onto the target channel resource of the multicast HARQ-ACK and feeding it back to the network side device includes: when the multicast HARQ-ACK includes a multicast dynamic HARQ-ACK, the terminal multiplexing the unicast HARQ-ACK and the multicast HARQ-ACK onto the third channel resource corresponding to the multicast dynamic HARQ-ACK and feeding it back to the network side device; or when the multicast HARQ-ACK includes only a multicast semi-static scheduling HARQ-ACK, the terminal multiplexing the unicast HARQ-ACK and the multicast HARQ-ACK onto the fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK and feeding it back to the network side device.

[0049] Specifically, when the multicast HARQ-ACK includes a multicast dynamic HARQ-ACK, a third channel resource corresponding to the multicast dynamic HARQ-ACK is adopted, where the third channel resource may be a PUCCH resource in the PUCCH resource list configured by the configuration parameter pucch-ConfigurationList-Multicast1 or pucch-ConfigurationList-Multicast2; when the multicast HARQ-ACK includes only a multicast semi-static scheduling HARQ-ACK, a fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK is adopted, where the fourth channel resource may be a PUCCH resource in the PUCCH resource list configured by the configuration parameter SPS-PUCCH-AN-List-Multicast. When the multicast HARQ-ACK includes a multicast dynamic HARQ-ACK, the target channel resource configured in the terminal is the third channel resource, and the terminal can adopt a feedback method of multiplexing the unicast HARQ-ACK and the multicast HARQ-ACK on the third channel resource and feeding it back to the network side device. When the multicast HARQ-ACK only includes a multicast semi-static scheduling HARQ-ACK, the target channel resource configured in the terminal is a fourth channel resource, and the terminal can adopt a feedback method of multiplexing the unicast HARQ-ACK and the multicast HARQ-ACK on the fourth channel resource and feeding it back to the network side device.

[0050] In this embodiment, when the network side device schedules unicast HARQ-ACK and multicast HARQ-ACK having the same priority to be fed back in the same time unit, and the first channel resource of the unicast HARQ-ACK is not configured in the terminal, if the multicast HARQ-ACK includes a multicast dynamic HARQ-ACK, the terminal can multiplex the unicast HARQ-ACK and multicast HARQ-ACK on a third channel resource and feed it back to the network side device in a feedback manner; if the multicast HARQ-ACK only includes a multicast semi-static scheduling HARQ-ACK, the terminal can multiplex the unicast HARQ-ACK and multicast HARQ-ACK on a fourth channel resource and feed it back to the network side device in a feedback manner, which realizes the feedback of HARQ-ACK and improves the reliability of communication.

[0051] In one embodiment, the target channel resource includes a fifth channel resource, and the fifth channel resource and the third channel resource corresponding to the multicast dynamic HARQ-ACK, or the fifth channel resource and the fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK, are configured based on different configuration parameters. In the above step 201, the terminal feeds back the multicast HARQ-ACK to the network side device via the target channel resource of the multicast HARQ-ACK, including: the terminal discarding the unicast HARQ-ACK and feeding back the multicast HARQ-ACK to the network side device via the fifth channel resource of the multicast HARQ-ACK in at least one of the following cases: 1. the third channel resource corresponding to the multicast dynamic HARQ-ACK and / or the fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK is not configured in the terminal; 2. the total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than a preset number of bits; or 3. the number of bits of the unicast HARQ-ACK is equal to or smaller than the number of bits of the multicast HARQ-ACK.

[0052] Specifically, the fifth channel resource may be a PUCCH resource configured by the configuration parameter n1PUCCH-AN (configured by the configuration of the multicast SPS PDSCH). The fifth channel resource and the above-mentioned third channel resource and fourth channel resource are configured based on different configuration parameters.

[0053] In the above case 1, since the third channel resource corresponding to the multicast dynamic HARQ-ACK and / or the fourth channel resource corresponding to the multicast semi-static scheduling HARQ-ACK is not configured in the terminal, the terminal cannot multiplex the unicast HARQ-ACK and the multicast HARQ-ACK on the third channel resource or the fourth channel resource and feed it back to the network side device. In such a case, a feedback method can be selected in which the unicast HARQ-ACK is discarded and the multicast HARQ-ACK is fed back to the network side device via the fifth channel resource of the multicast HARQ-ACK.

[0054] In the above case 2, the preset number of bits may be 2 bits, and since the total number of bits of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than 2 bits, assuming that the second channel resource of the unicast HARQ-ACK can transmit up to 2 bits, in such a case, a feedback method can be selected in which the unicast HARQ-ACK is discarded and the multicast HARQ-ACK is fed back to the network side device via the fifth channel resource of the multicast HARQ-ACK.

[0055] In the above case 3, the number of bits of the unicast HARQ-ACK is less than or equal to the number of bits of the multicast HARQ-ACK, and a feedback method can be selected in which the unicast HARQ-ACK with a relatively small number of bits is discarded and the multicast HARQ-ACK is fed back to the network side device via the fifth channel resource of the multicast HARQ-ACK.

[0056] In this embodiment, when the network side device schedules unicast HARQ-ACK and multicast HARQ-ACK having the same priority to be fed back in the same time unit, and the first channel resource of the unicast HARQ-ACK is not configured in the terminal, a feedback method can be selected in at least one of the above cases to discard the unicast HARQ-ACK and feed back the multicast HARQ-ACK to the network side device via the fifth channel resource of the multicast HARQ-ACK, thereby realizing feedback of the HARQ-ACK and improving the reliability of communication.

[0057] Optionally, the method further includes: when a first channel resource of a unicast HARQ-ACK is configured in the terminal, and a transmission code rate of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than a preset code rate, the terminal partially discards the multicast HARQ-ACK until the transmission code rate of the unicast HARQ-ACK and the remaining multicast HARQ-ACK is equal to or less than the preset code rate, and multiplexes the unicast HARQ-ACK and the remaining multicast HARQ-ACK on the first channel resource of the unicast HARQ-ACK or the target channel resource of the multicast HARQ-ACK, and feeds back to the network side device.

[0058] Specifically, the preset code rate is the maximum code rate corresponding to the first channel resource of the unicast HARQ-ACK or 1. If the transmission code rate of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than the preset code rate, the unicast HARQ-ACK cannot be transmitted through the first channel resource of the unicast HARQ-ACK, and the terminal can select a feedback manner of partially discarding the multicast HARQ-ACK until the transmission code rate of the unicast HARQ-ACK and the remaining multicast HARQ-ACK is equal to or less than the preset code rate, and multiplexing the unicast HARQ-ACK and the remaining multicast HARQ-ACK on the first channel resource of the unicast HARQ-ACK or the target channel resource of the multicast HARQ-ACK to feed back to the network side device.

[0059] In this embodiment, when the network side device schedules the unicast HARQ-ACK and the multicast HARQ-ACK having the same priority to be fed back in the same time unit, and the first channel resource of the unicast HARQ-ACK is configured in the terminal, if the transmission code rate of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than the preset code rate, the terminal can select a feedback method of partially discarding the multicast HARQ-ACK until the transmission code rate of the unicast HARQ-ACK and the remaining multicast HARQ-ACK is equal to or less than the preset code rate, and multiplexing the unicast HARQ-ACK and the remaining multicast HARQ-ACK on the first channel resource of the unicast HARQ-ACK or the target channel resource of the multicast HARQ-ACK to feed back to the network side device, thereby realizing the feedback of the HARQ-ACK and improving the reliability of communication.

[0060] Optionally, before the network side device schedules the unicast HARQ-ACK and the multicast HARQ-ACK having the same priority to be fed back in the same time unit, it configures the first channel resource of the unicast HARQ-ACK, i.e., the resource list SPS-PUCCH-AN-List corresponding to the unicast HARQ-ACK, in the terminal, i.e., the terminal does not expect the first channel resource for which the unicast HARQ-ACK is not configured.

[0061] Optionally, the method further includes: when a first channel resource of a unicast HARQ-ACK is configured in the terminal, and a transmission code rate of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than a preset code rate and the transmission code rate of the unicast HARQ-ACK is equal to or less than the preset code rate, the terminal discards all the multicast HARQ-ACKs and feeds back the unicast HARQ-ACKs via the first channel resource of the unicast HARQ-ACK.

[0062] Specifically, the preset code rate is the maximum code rate corresponding to the first channel resource of the unicast HARQ-ACK or 1. If the transmission code rate of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than the preset code rate, it cannot be transmitted through the first channel resource of the unicast HARQ-ACK, and the terminal can choose to discard all the multicast HARQ-ACK, and feed back the unicast HARQ-ACK through the first channel resource of the unicast HARQ-ACK when the transmission code rate of the unicast HARQ-ACK is equal to or less than the preset code rate.

[0063] In this embodiment, when a network side device schedules unicast HARQ-ACK and multicast HARQ-ACK having the same priority to be fed back in the same time unit, and a first channel resource of unicast HARQ-ACK is configured in a terminal, if the transmission code rate of the unicast HARQ-ACK and the multicast HARQ-ACK is greater than a preset code rate, the terminal can select a feedback method of discarding all multicast HARQ-ACKs and feeding back unicast HARQ-ACKs via the first channel resource of unicast HARQ-ACK, thereby realizing feedback of HARQ-ACK and improving communication reliability.

[0064] Optionally, before the network side device schedules the unicast HARQ-ACK and the multicast HARQ-ACK having the same priority to be fed back in the same time unit, the transmission code rate on the first channel resource constituting the unicast HARQ-ACK to the terminal is greater than a preset code rate, i.e., the terminal does not expect the code rate of the unicast HARQ-ACK and the multicast HARQ-ACK transmitted on the first channel resource of the unicast HARQ-ACK to exceed the maximum code rate or exceed 1. That is, the network side device ensures that the first channel resource of the configured unicast HARQ-ACK is sufficient to transmit the feedback of the unicast HARQ-ACK and the multicast HARQ-ACK.

[0065] In this embodiment, in order to ensure that the first channel resource of the unicast HARQ-ACK configured by the network side device is sufficient to transmit the feedback of the unicast HARQ-ACK and the multicast HARQ-ACK, when the network side device schedules the unicast HARQ-ACK and the multicast HARQ-ACK having the same priority to be fed back in the same time unit and the first channel resource of the unicast HARQ-ACK is configured in the terminal, the terminal can multiplex the unicast HARQ-ACK and the multicast HARQ-ACK on the first channel resource of the unicast HARQ-ACK and select a feedback method to feed back to the network side device, thereby realizing the feedback of the HARQ-ACK and improving the reliability of communication.

[0066] Optionally, the method further includes, when a first channel resource of a unicast HARQ-ACK is configured in the terminal and the transmission code rate of the unicast HARQ-ACK and the multicast HARQ-ACK is equal to or lower than a preset code rate, the terminal multiplexes the unicast HARQ-ACK and the multicast HARQ-ACK onto the first channel resource of the unicast HARQ-ACK, and feeds back the multiplexed HARQ-ACK and the multicast HARQ-ACK to the network side device.

[0067] Specifically, the preset code rate is the maximum code rate corresponding to the first channel resource of the unicast HARQ-ACK or 1. If the transmission code rate of the unicast HARQ-ACK and the multicast HARQ-ACK is equal to or lower than the preset code rate, the first channel resource of the unicast HARQ-ACK is configured in the terminal, so that the second channel resource of the unicast HARQ-ACK is unavailable, and the terminal can multiplex the unicast HARQ-ACK and the multicast HARQ-ACK on the first channel resource of the unicast HARQ-ACK and feed it back to the network side device.

[0068] In this embodiment, when the network side device schedules unicast HARQ-ACK and multicast HARQ-ACK having the same priority to be fed back in the same time unit, and a first channel resource of the unicast HARQ-ACK is configured in the terminal, if the transmission code rate of the unicast HARQ-ACK and the multicast HARQ-ACK is equal to or lower than a preset code rate, the terminal can multiplex the unicast HARQ-ACK and the multicast HARQ-ACK on the first channel resource of the unicast HARQ-ACK and select a feedback method to feed back to the network side device, thereby realizing feedback of the HARQ-ACK and improving the reliability of communication.

[0069] HARQ-ACK may have high and low priority, and its priority is represented by a priority index. Here, priority index represents high priority, and priority index 0 represents low priority. The priority of HARQ-ACK may be indicated by RRC or scheduling DCI. HARQ-ACK of different priority corresponds to different HARQ-ACK codebook. It should be noted that in this application, the method in each of the above embodiments has the same processing process for high priority or low priority, and will not be further described here.
