In the embodiments of the present application, only a base station in an NR system is taken as an example, but the specific type of the base station is not limited.

[0018] In the following, the technical means provided in the embodiments of the present application will be described in detail through several embodiments and their use cases with reference to the drawings.

[0019] 2 shows a flowchart of a PUCCH resource determination method 200 provided in an exemplary embodiment of the present application, which may be, but is not limited to, performed by a terminal. Specifically, the method may be performed by hardware and / or software implemented in the terminal. In this embodiment, the method 200 may include at least the following step S210:

[0020] In S210, when multiple SPS PDSCHs are configured or activated in the terminal, and feedback information corresponding to at least one target SPS PDSCH among the multiple SPS PDSCHs needs to be fed back in the same time unit, determine a first target Physical Uplink Control Channel (PUCCH) resource.

[0021] It can be understood that the feedback information corresponding to at least one target SPS PDSCH needs to be fed back in the same time unit means that the multiple SPS PDSCHs are determined to be instructed to transmit feedback information in the same time unit by a HARQ-ACK feedback timing indication corresponding to each of the multiple target SPS PDSCHs (e.g., a value indicated in a PDSCH HARQ-ACK feedback timing indication domain in an activation downlink control information (DCI) corresponding to an SPS PDSCH). However, in a NACK only mode, when a certain SPS PDSCH is instructed to be fed back in a certain time unit, the terminal needs to transmit a NACK only in the case of a NACK, and does not need to transmit the feedback information otherwise.

[0022] The term "multiple SPS PDSCHs are configured or activated in the terminal" may be understood to mean that the terminal may configure or activate multiple SPS PDSCHs in one or multiple serving cells to enable the terminal to support a variety of different service types. Optionally, an SPS PDSCH among the multiple SPS PDSCHs may be an SPS group common PDSCH or an SPS unicast PDSCH, and correspondingly, the target SPS PDSCH may be an SPS group common PDSCH or an SPS unicast PDSCH, which is not limited herein.

[0023] In addition, the first target PUCCH resource is used to transmit feedback information corresponding to the target SPS PDSCH, and the time unit may be a slot, a sub-slot, a symbol, a symbol set, or the like.

[0024] In this embodiment, the target SPS PDSCH is taken as an SPS group common PDSCH as an example. Before the terminal feeds back feedback information corresponding to at least one SPS group common PDSCH in the same time unit, the terminal determines a HARQ feedback resource (i.e., a first target PUCCH resource) corresponding to at least one SPS group common PDSCH, thereby solving the problem that the terminal cannot clearly determine a feedback resource for transmitting feedback information due to the need to feed back feedback information corresponding to multiple SPS PDSCHs in a certain time unit, ensuring that the feedback information is normally fed back, and improving the performance of the wireless communication system.

[0025] It can be understood that the manner in which the terminal determines the first target PUCCH resource may be various, for example, based on the identifier information of the target SPS PDSCH, the HARQ feedback mode (i.e., the feedback manner, for example, the mode of feedback of HARQ-ACK / NACK, etc.) of the target SPS PDSCH configuration, and is not limited thereto.

[0026] 3 shows a flowchart of a PUCCH resource determination method 300 provided in an exemplary embodiment of the present application. The method may be performed by a terminal, but is not limited thereto, specifically by hardware and / or software implemented in the terminal. In this embodiment, the method 300 may include at least the following step S310:

[0027] In S310, when multiple SPS PDSCHs are configured or activated in the terminal, and feedback information corresponding to at least one target SPS PDSCH among the multiple SPS PDSCHs needs to be fed back in the same time unit, a first target PUCCH resource is determined.

[0028] Here, the first target PUCCH resource is used to transmit feedback information corresponding to the target SPS PDSCH.

[0029] For the implementation step of S310, reference can be made to the relevant description in the embodiment 200 of the above method. In addition, it can be understood that, as a possible implementation form, the implementation step of "determining a first target PUCCH resource" in S310 may include determining the first target PUCCH resource according to a HARQ feedback mode corresponding to the target SPS PDSCH, where the HARQ feedback mode may include at least one of the following items (1)-(3): (1) A mode in which HARQ information is not fed back: That is, when a terminal receives an SPS PDSCH in which a mode in which the HARQ information is not fed back is configured, the terminal does not feed back an HARQ-ACK or HARQ-NACK corresponding to the SPS PDSCH to a network side device. (2) A mode in which only HARQ-NACK is fed back: That is, when the terminal receives an SPS PDSCH in which the mode in which only the HARQ-NACK is fed back is configured, the terminal feeds back only the HARQ-NACK corresponding to the SPS PDSCH to the network side device. (3) Mode for feeding back HARQ-ACK / NACK. That is, when the terminal receives an SPS PDSCH in which the mode for feeding back HARQ-ACK / NACK is configured, the terminal can feed back HARQ-ACK or HARQ-NACK corresponding to the SPS PDSCH to the network side device. In one implementation form, in the case of an SPS unicast PDSCH, no configuration or instruction by the network side device is required, and the HARQ feedback mode corresponding to the SPS unicast PDSCH may be HARQ-ACK / NACK by default.

[0030] In this embodiment, the HARQ feedback mode corresponding to the SPS PDSCH may be configured by an existing parameter in the SPS-configuration (Config), for example, the semiPersistSchedC-RNTI field, or may be configured by adding a new RRC parameter in the SPS-Config, for example, HARQ-ACKFeedback{enable, disable} or HARQ-ACKFeedback{no feedback, ACK / NACK, NACK only}, or may be configured by other methods, and is not limited here.

[0031] In this case, in one implementation, in order to further improve the efficiency of determining the first target PUCCH resource, the terminal may be configured with a feedback resource (which may be understood as a feedback resource list or set) for configuring a PUCCH resource corresponding to an SPS PDSCH. Optionally, the feedback resource may include at least one of the following first resource, second resource, and third resource: The first resource is a PUCCH resource for transmitting feedback information corresponding to a first SPS group common PDSCH, and the HARQ feedback mode corresponding to the first SPS group common PDSCH is a mode for feeding back the HARQ-ACK / NACK. The second resource is a PUCCH resource for transmitting feedback information corresponding to a second SPS group common PDSCH, and the HARQ feedback mode corresponding to the second SPS group common PDSCH is a mode for feeding back only the HARQ-NACK. The third resource is a PUCCH resource for transmitting feedback information corresponding to the SPS unicast PDSCH.

[0032] It should be noted that, regarding the above first resource, second resource, and third resource, the first resource is taken as an example here, and one or more PUCCH resources may be configured in the first resource, and any PUCCH resource in the first resource may be dedicated to transmitting feedback information corresponding to a certain SPS PDSCH, or may be used to transmit feedback information corresponding to each SPS PDSCH configured with a specific HARQ feedback mode, and is not limited thereto.

[0033] According to the above-mentioned HARQ feedback mode and feedback resource, the process of the terminal determining the first target PUCCH resource according to the HARQ feedback mode corresponding to the target SPS PDSCH may include any one of the following Schemes 1 to 3.

[0034] In manner 1, when the HARQ feedback mode corresponding to the target SPS PDSCH is a mode for feeding back the HARQ-ACK / NACK and the target SPS PDSCH is an SPS group common PDSCH, the first target PUCCH resource is determined according to the number of bits of the HARQ-ACK / NACK corresponding to the target SPS PDSCH.

[0035] For example, the terminal may determine the first target PUCCH resource from one or more PUCCH resources configured in the first resource according to the number of HARQ-ACK / NACK bits corresponding to a target SPS PDSCH.

[0036] In manner 2, if the HARQ feedback mode corresponding to the target SPS PDSCH is a mode for feeding back only the HARQ-NACK and the target SPS PDSCH is an SPS group common PDSCH, determine a first PUCCH resource as the first target PUCCH resource.

[0037] Wherein, the first PUCCH resource is a PUCCH resource configured under the target SPS PDSCH. In other words, the first PUCCH resource is dedicated to transmitting feedback information corresponding to the target SPS PDSCH. In this embodiment, the first PUCCH resource may be defined by a protocol, or may be configured by a network side device (for example, a base station), for example, may be configured by a parameter n1 PUCCH-AN in SPS-config, and is not limited thereto.

[0038] In manner 3, if the HARQ feedback mode corresponding to the target SPS PDSCH is a mode for feeding back only the HARQ-NACK and the target SPS PDSCH is an SPS group common PDSCH, a second PUCCH resource is determined as the first target PUCCH resource.

[0039] Here, the second PUCCH resource is for transmitting feedback information of any SPS group common PDSCH configured with the mode of feeding back only HARQ-NACK. In other words, each SPS group common PDSCH configured with the mode of feeding back only HARQ-NACK can transmit its corresponding feedback information by the second PUCCH resource. In this embodiment, the second PUCCH resource may be defined by a protocol or configured by a network side device (e.g., a base station), for example, may be configured by an upper layer parameter SPS-PUCCH-NACKOnly-r17 or SPS-PUCCH-NOnly-r17, and is not limited thereto.

[0040] In the above-mentioned methods 2 and 3, it is understandable that the first PUCCH resource and the second PUCCH resource may be selected from resources arranged in the above-mentioned first resource, second resource, and third resource, or may be resources other than the resources arranged in the above-mentioned first resource, second resource, and third resource, and is not limited here.

[0041] Furthermore, the terminal may determine the first target PUCCH resource according to the HARQ feedback mode corresponding to the target SPS PDSCH, and then transmit feedback information corresponding to the target SPS PDSCH based on the first target PUCCH resource. However, since feedback information corresponding to multiple target SPS PDSCHs may need to be fed back in the same time unit, a transmission collision problem may occur. For example, feedback information corresponding to multiple target SPS PDSCHs (e.g., SPS group common PDSCHs) is transmitted in the same time unit, and a HARQ feedback mode that feeds back only HARQ-NACK is configured in some SPS group common PDSCHs, but a HARQ feedback mode of HARQ-ACK / NACK is configured in some SPS group common PDSCHs. That is, considering that the terminal needs to feed back not only ACK / NACK but also NACK in the same time unit, how does the terminal transmit? In this regard, the present embodiment will describe a transmission process with reference to the following examples 1 to 3.

[0042] (Example 1) When a terminal needs to feed back feedback information corresponding to multiple target SPS PDSCHs in the same time unit, and the HARQ feedback modes corresponding to the target SPS PDSCHs are all modes for feeding back only the HARQ-NACK, the terminal may implement any one of the following (1) to (3):

[0043] (1) When one of the target SPS PDSCHs among the plurality of target SPS PDSCHs requires feedback of a NACK, the NACK is fed back based on the first target PUCCH resource, and the first target PUCCH resource is a PUCCH resource configured under the target SPS PDSCH requiring feedback of a NACK. In other words, the first target PUCCH resource is dedicated to transmitting feedback information corresponding to the target SPS PDSCH requiring feedback of the NACK, or the first target PUCCH resource is for transmitting feedback information of any SPS group common PDSCH configured with a mode for feeding back only the HARQ-NACK. In other words, each SPS group common PDSCH configured with a mode for feeding back only the HARQ-NACK can transmit its corresponding feedback information through the first target PUCCH resource.

[0044] For example, when one of multiple target SPS PDSCHs needs to feed back a NACK, each target SPS PDSCH has its own PUCCH resource for NACK feedback (i.e., a first target PUCCH resource), and the terminal determines which PUCCH resource to use by itself. When a NACK is fed back on a certain PUCCH resource, it means that a NACK corresponding to this target SPS PDSCH has been fed back. When the base station performs blind detection on multiple PUCCH resources, it can determine which target SPS PDSCH the terminal has fed back the NACK on based on which PUCCH resource the NACK was detected on.

[0045] Furthermore, for example, when one of multiple target SPS PDSCHs needs to feed back a NACK, if the PUCCH resource for NACK feedback of all target SPS PDSCHs (i.e., the first target PUCCH resource) is the same, the feedback information corresponding to one of the target SPS PDSCHs is a NACK, and the terminal feeds back the NACK on this PUCCH resource. In this case, the base station detects whether the terminal has transmitted a NACK on this PUCCH, and when the base station detects the NACK fed back on the PUCCH, it can determine that at least one of these target SPS PDSCHs is a NACK, but cannot determine which SPS PDSCH the NACK corresponds to.

[0046] (2) When only one SPS PDSCH among the multiple target SPS PDSCHs requires feedback of a NACK, the NACK is fed back based on a first target PUCCH resource corresponding to the SPS PDSCH requiring feedback of a NACK.

[0047] (3) When at least two SPS PDSCHs among the plurality of target SPS PDSCHs require feedback of a NACK, a NACK corresponding to the first designated SPS PDSCH is fed back based on a first target PUCCH resource corresponding to a first designated SPS PDSCH, and the first designated SPS PDSCH is determined from the at least two SPS PDSCHs requiring feedback of a NACK based on first information, or the first designated SPS PDSCH is any one of the at least two target SPS PDSCHs determined by the terminal.

[0048] Optionally, when the first designated SPS PDSCH is determined from the at least two SPS PDSCHs requiring feedback of a NACK based on first information, the first information may include at least one of priority information of an SPS PDSCH, priority information of feedback information of an SPS PDSCH, traffic priority information corresponding to an SPS PDSCH, configuration index information corresponding to an SPS PDSCH, serving cell index information where the SPS PDSCH is located, and SPS PDSCH reception time information.

[0049] For example, when the first information includes priority information of an SPS PDSCH, the first designated SPS PDSCH may be an SPS PDSCH having the highest SPS PDSCH priority among the at least two SPS PDSCHs. It is understood that when the first information is priority information of feedback information of an SPS PDSCH, traffic priority information corresponding to an SPS PDSCH, or configuration index information corresponding to an SPS PDSCH, the determination of the first designated SPS PDSCH is similar to the case of the priority information of the SPS PDSCH, and detailed description thereof will be omitted herein.

[0050] Furthermore, for example, in a case where the first information includes priority information of an SPS PDSCH and traffic priority information corresponding to the SPS PDSCH, if at least two SPS PDSCHs include SPS PDSCH1, SPS PDSCH2, and SPS PDSCH3, a first designated SPS PDSCH may be selected from SPS PDSCH1, SPS PDSCH2, and SPS PDSCH3 according to the priority information of the SPS PDSCH first, and if the first designated SPS PDSCH can be selected, the traffic priority information corresponding to the SPS PDSCH is not taken into consideration; otherwise, the first designated SPS PDSCH is continuously selected from SPS PDSCH1, SPS PDSCH2, and SPS PDSCH3 according to the traffic priority information corresponding to the SPS PDSCH. It is understood that, when the first information includes at least two of priority information of an SPS PDSCH, priority information of feedback information of an SPS PDSCH, traffic priority information corresponding to an SPS PDSCH, configuration index information corresponding to an SPS PDSCH, index information of a serving cell in which an SPS PDSCH is located, and reception time information of an SPS PDSCH, the selection of the first designated SPS PDSCH may be as described above, and detailed description thereof will be omitted here.

[0051] (Example 2) When at least one of the target SPS PDSCHs includes a first SPS PDSCH and a second SPS PDSCH and feedback information corresponding to the first SPS PDSCH and feedback information corresponding to the second SPS PDSCH need to be fed back in the same time unit, the terminal performs at least one of the following (1) to (5):

[0052] (1) According to a first target PUCCH resource corresponding to the first SPS PDSCH, feed back a HARQ-ACK / NACK corresponding to the first SPS PDSCH, where the HARQ feedback mode corresponding to the first SPS PDSCH is a mode for feeding back the HARQ-ACK / NACK, and the HARQ feedback mode corresponding to the second SPS PDSCH is a mode for feeding back only the HARQ-NACK.

[0053] For example, even if an SPS group-common PDSCH (i.e., a mode in which only HARQ-NACK is fed back) configured with NACK only (i.e., a mode in which only HARQ-NACK is fed back) corresponds to NACK, the terminal does not feed back the NACK corresponding to the SPS group-common PDSCH. That is, the terminal only feeds back the HARQ-ACK / NACK corresponding to the SPS group-common PDSCH (i.e., the first SPS PDSCH) configured with ACK / NACK.

[0054] (2) Based on a first target PUCCH resource corresponding to the second SPS PDSCH, a HARQ-NACK corresponding to the second SPS PDSCH is fed back, the HARQ feedback mode corresponding to the first SPS PDSCH is a mode for feeding back the HARQ-ACK / NACK, and the HARQ feedback mode corresponding to the second SPS PDSCH is a mode for feeding back only the HARQ-NACK.

[0055] For example, when an SPS group-common PDSCH in which only NACK is configured (i.e., the second SPS PDSCH) corresponds to a NACK, the terminal feeds back a NACK corresponding to the SPS group-common PDSCH, but does not feed back a HARQ-ACK / NACK of an SPS group-common PDSCH in which ACK / NACK is configured (i.e., the first SPS PDSCH).

[0056] (3) Feedback information corresponding to a second designated SPS PDSCH is fed back based on a first target feedback resource corresponding to a second designated SPS PDSCH, the second designated SPS PDSCH is determined from the first SPS PDSCH and the second SPS PDSCH based on second information, the HARQ feedback mode corresponding to the first SPS PDSCH is a mode for feeding back the HARQ-ACK / NACK, and the HARQ feedback mode corresponding to the second SPS PDSCH is a mode for feeding back only the HARQ-NACK.

[0057] For related descriptions of the second information, reference may be made to the description of the first information above, and detailed descriptions thereof will be omitted here to avoid repetition.

[0058] For example, assuming that the second information is priority information of the SPS PDSCH, if the SPS group-common PDSCH in which only NACK is arranged (i.e., the second SPS PDSCH) corresponds to the NACK and has a lower priority than the SPS group-common PDSCH in which any / at least one ACK / NACK is arranged (i.e., the first SPS PDSCH), the terminal feeds back the HARQ-ACK of the SPS group-common PDSCH in which ACK / NACK is arranged, otherwise, the terminal is N ACK only The NACK of the SPS group-common PDSCH in which the .DELTA..times ...

[0059] (4) When the feedback information corresponding to the second SPS PDSCH is not a NACK, a HARQ-ACK / NACK corresponding to the first SPS PDSCH is fed back based on a first target feedback resource corresponding to a third designated SPS PDSCH, the third designated SPS PDSCH is determined from the first SPS PDSCH and the second SPS PDSCH based on third information, the HARQ feedback mode corresponding to the first SPS PDSCH is a mode for feeding back the HARQ-ACK / NACK, and the HARQ feedback mode corresponding to the second SPS PDSCH is a mode for feeding back only the HARQ-NACK.

[0060] (5) Based on a first target PUCCH resource corresponding to the first SPS PDSCH, a HARQ-ACK / NACK corresponding to the first SPS PDSCH and a HARQ-NACK corresponding to the second SPS PDSCH are fed back, the HARQ feedback mode corresponding to the first SPS PDSCH is a mode for feeding back the HARQ-ACK / NACK, and the HARQ feedback mode corresponding to the second SPS PDSCH is a mode for feeding back only the HARQ-NACK.

[0061] For example, even for an SPS group-common PDSCH (i.e., the second SPS PDSCH) in which only NACK is configured, the terminal feeds back a HARQ-ACK / NACK. That is, the terminal not only feeds back a HARQ-ACK / NACK corresponding to an SPS group-common PDSCH (i.e., the first SPS PDSCH) in which ACK / NACK is configured, but also feeds back a HARQ-ACK / NACK corresponding to an SPS group-common PDSCH in which only NACK is configured.

[0062] It should be noted that in the above Example 2, the first SPS PDSCH may include an SPS group common PDSCH or an SPS unicast PDSCH, and the second SPS PDSCH includes an SPS group common PDSCH. In other words, when the first SPS PDSCH may include an SPS group common PDSCH and the second SPS PDSCH includes an SPS group common PDSCH, or when the first SPS PDSCH includes an SPS unicast PDSCH and the second SPS PDSCH includes an SPS group common PDSCH, the terminal can feed back a plurality of pieces of feedback information in the transmission manner provided in the above Example 2.

[0063] (Example 3) When at least one of the target SPS PDSCHs includes a third SPS PDSCH and a fourth SPS PDSCH and feedback information corresponding to the third SPS PDSCH and feedback information corresponding to the fourth SPS PDSCH need to be fed back in the same time unit, the terminal implements the transmission method provided in the following (1) or (2), where the third SPS PDSCH is an SPS group common PDSCH and the fourth SPS PDSCH is an SPS unicast PDSCH.

[0064] (1) Based on a first target PUCCH resource corresponding to a fourth designated SPS PDSCH, feedback information corresponding to the fourth designated SPS PDSCH is fed back, and the fourth designated SPS PDSCH is determined from the third SPS PDSCH and the fourth SPS PDSCH based on fourth information.

[0065] For example, the terminal may determine whether to feed back only a HARQ-ACK corresponding to an SPS group-common PDSCH (i.e., the third SPS PDSCH) or only a HARQ-ACK corresponding to an SPS unicast PDSCH (i.e., the fourth SPS PDSCH) according to the fourth information. Here, for the fourth information and a process of determining a fourth designated SPS PDSCH according to the fourth information, reference may be made to the above description of the first information, and detailed description thereof will be omitted here to avoid duplication.

[0066] (2) The feedback information corresponding to the third SPS PDSCH and the feedback information corresponding to the fourth SPS PDSCH are multiplexed and then fed back.

[0067] Here, compared with the above (1) in which the terminal feeds back only one feedback information, in this implementation, the feedback information corresponding to the 3rd SPS PDSCH and the feedback information corresponding to the 4th SPS PDSCH are multiplexed in a manner to ensure the completeness of the feedback information.

[0068] In this embodiment, the feedback step of the terminal multiplexing and feeding back feedback information corresponding to the third SPS PDSCH and feedback information corresponding to the fourth SPS PDSCH may include a step of the terminal performing at least one of the following (2a)-(2e) when the third SPS PDSCH and the fourth SPS PDSCH correspond to different PUCCH configurations (PUCCH-config). Here, in the following (2a)-(2e), the fourth PUCCH resource is for feeding back a HARQ-ACK corresponding to an SPS unicast PDSCH, the fifth PUCCH resource is for feeding back a HARQ-ACK corresponding to the SPS group common PDSCH, and the target HARQ-ACK is obtained after multiplexing a HARQ-ACK corresponding to the third SPS PDSCH and a HARQ-ACK corresponding to the fourth SPS PDSCH.

[0069] (2a) When at least one fourth PUCCH resource is arranged in a PUCCH arrangement corresponding to the fourth SPS PDSCH, a second target PUCCH resource is selected from the at least one fourth PUCCH resource according to the number of bits of a target HARQ-ACK, and the target HARQ-ACK is fed back based on the second target PUCCH resource.

[0070] Specifically, when one or more PUCCH resources for feeding back an SPS unicast PDSCH HARQ-ACK are configured in a PUCCH-config corresponding to an SPS unicast PDSCH, for example, when an SPS-PUCCH-AN-List-r16 is configured, the terminal may select and multiplex one PUCCH resource from the PUCCH resources configured in the SPS-PUCCH-AN-List-r16 corresponding to the SPS unicast PDSCH according to the number of bits of a target HARQ-ACK after multiplexing.

[0071] (2b) In the case where a fourth PUCCH resource is not allocated to the PUCCH allocation corresponding to the fourth SPS PDSCH but a fifth PUCCH resource is allocated to the PUCCH allocation corresponding to the third SPS PDSCH, a second target PUCCH resource is selected from at least one of the fifth PUCCH resources corresponding to the third SPS PDSCH according to the number of bits of a target HARQ-ACK, and the target HARQ-ACK is fed back based on the second target PUCCH resource.

[0072] For example, in the case where one or more PUCCH resources for feeding back an SPS unicast PDSCH HARQ-ACK are not configured in the PUCCH-config corresponding to the SPS unicast PDSCH, e.g., SPS-PUCCH-AN-List-r16 is not configured, but one or more PUCCH resources for feeding back an SPS unicast PDSCH HARQ-ACK are configured in the PUCCH-config corresponding to the SPS group-common PDSCH, e.g., SPS-PUCCH-AN-List-r16 is configured, the terminal may select and multiplex one PUCCH resource from the PUCCH resources configured in SPS-PUCCH-AN-List-r16 corresponding to the SPS group-common PDSCH according to the number of bits of a target HARQ-ACK after multiplexing.

[0073] (2c) When a fifth PUCCH resource is not allocated in the PUCCH allocation corresponding to the third SPS PDSCH and a fourth PUCCH resource is not allocated in the PUCCH allocation corresponding to the fourth SPS PDSCH, a HARQ-ACK corresponding to the third SPS PDSCH is fed back based on a first target PUCCH resource corresponding to the third SPS PDSCH, or a HARQ-ACK corresponding to the fourth SPS PDSCH is fed back based on a first target PUCCH resource corresponding to the fourth SPS PDSCH.

[0074] For example, when SPS-PUCCH-AN-List-r16 is not configured in either the PUCCH-config corresponding to the SPS unicast PDSCH or the PUCCH-config corresponding to the group-common PDSCH, the terminal may discard the HARQ-ACK corresponding to the SPS group-common PDSCH, or may discard the HARQ-ACK corresponding to the SPS unicast PDSCH. That is, the terminal only feeds back the HARQ-ACK corresponding to the SPS unicast PDSCH or the HARQ-ACK corresponding to the SPS group-common PDSCH.

[0075] (2d) When a fifth PUCCH resource is not allocated to the PUCCH allocation corresponding to the third SPS PDSCH and a fourth PUCCH resource is not allocated to the PUCCH allocation corresponding to the fourth SPS PDSCH, a target HARQ-ACK is fed back based on a first target PUCCH resource corresponding to the third SPS PDSCH, or a target HARQ-ACK is fed back based on a PUCCH resource corresponding to the fourth SPS PDSCH.

[0076] For example, if SPS-PUCCH-AN-List-r16 is not placed in either the PUCCH-config corresponding to the SPS unicast PDSCH or the PUCCH-config corresponding to the group-common PDSCH, the HARQ-ACK of the SPS group-common PDSCH and the HARQ-ACK of the SPS unicast PDSCH are multiplexed onto the PUCCH resource corresponding to the SPS group-common PDSCH, or multiplexed onto the PUCCH resource corresponding to the SPS unicast PDSCH and fed back.

[0077] (2e) When at least one fifth PUCCH resource is arranged in the PUCCH arrangement corresponding to the third SPS PDSCH, a second target PUCCH resource is selected from the at least one fifth PUCCH resource according to the number of bits of a target HARQ-ACK, and the target HARQ-ACK is fed back based on the second target PUCCH resource.

[0078] For example, when one or more PUCCH resources for feeding back a HARQ-ACK corresponding to an SPS group-common PDSCH are configured in a PUCCH-config corresponding to an SPS group-common PDSCH, for example, when an SPS-PUCCH-AN-List-r16 is configured, the terminal may select one PUCCH resource from the PUCCH resources configured in the SPS-PUCCH-AN-List-r16 corresponding to the SPS group-common PDSCH according to the number of bits of the target HARQ-ACK after multiplexing, and feed back the target HARQ-ACK.

[0079] (2f) In the case where a fifth PUCCH resource is not allocated to the PUCCH allocation corresponding to the third SPS PDSCH but a fourth PUCCH resource is allocated to the PUCCH allocation corresponding to the fourth SPS PDSCH, a second target PUCCH resource is selected from at least one of the fourth PUCCH resources corresponding to the fourth SPS PDSCH according to the number of bits of a target HARQ-ACK, and the target HARQ-ACK is fed back based on the second target PUCCH resource.

[0080] For example, one or more PUCCH resources for feeding back a HARQ-ACK corresponding to an SPS group-common PDSCH are not configured in a PUCCH-config corresponding to a group-common PDSCH, i.e., SPS-PUCCH-AN-List-r16 is not configured. However, when one or more PUCCH resources for feeding back a HARQ-ACK corresponding to an SPS unicast PDSCH are configured in a PUCCH-config corresponding to an SPS unicast PDSCH, i.e., SPS-PUCCH-AN-List-r16 is configured, the terminal may select one PUCCH resource from the PUCCH resources configured in SPS-PUCCH-AN-List-r16 corresponding to the SPS group-common PDSCH according to the number of bits of the target HARQ-ACK after multiplexing to feed back the target HARQ-ACK.

[0081] Optionally, in the above (2a)-(2e), the feedback information corresponding to the third SPS PDSCH and the feedback information corresponding to the fourth SPS PDSCH have the same priority, and the HARQ feedback mode corresponding to the third SPS PDSCH is a mode for feeding back HARQ-ACK / NACK.

[0082] In one possible implementation form, when the terminal multiplexes the HARQ-ACK corresponding to the third SPS PDSCH and the HARQ-ACK corresponding to the fourth SPS PDSCH to obtain the target HARQ-ACK, the terminal processes (e.g., compresses or bundles) the number of bits of the target HARQ-ACK into a scheduled number of bits, and the scheduled number of bits may be 1 bit or 2 bits, and is not limited thereto.

[0083] In this embodiment, when feedback information corresponding to multiple SPS PDSCHs needs to be transmitted in the same time unit, the terminal can determine which SPS PDSCH the feedback information corresponding to needs to be transmitted and the PUCCH resource to be adopted according to the HARQ feedback mode corresponding to the SPS PDSCH and / or the type of SPS PDSCH (e.g., SPS group common PDSCH, SPS unicast PDSCH), thereby ensuring normal transmission of the feedback information and improving the performance of the wireless communication system.

[0084] 4 shows a flowchart of a PUCCH resource determination method 400 provided in an exemplary embodiment of the present application. The method may be performed by a terminal, but is not limited thereto, specifically by hardware and / or software implemented in the terminal. In this embodiment, the method 400 may include at least the following steps S410 and S420.

[0085] In S410, when multiple SPS PDSCHs are configured or activated in the terminal and feedback information corresponding to at least one target SPS PDSCH among the multiple SPS PDSCHs needs to be fed back in the same time unit, determine the first target PUCCH resource according to a HARQ feedback mode corresponding to the target SPS PDSCH.

[0086] It can be understood that the implementation process of S410 may refer to the relevant description in the above method embodiment 200 or 300, and detailed description thereof will be omitted here to avoid repetition.

[0087] In S420, when feedback information corresponding to the target SPS PDSCHs is fed back in the same time unit, a first target codebook is generated according to a scheduling manner, and the first target codebook is determined according to feedback information corresponding to the target SPS PDSCHs, and the scheduling manner includes the following Scheme 1 and / or Scheme 2:

[0088] In the first method, the first target codebook is generated based on a scheduled order including at least one of a magnitude of a configuration index corresponding to the target SPS PDSCH, an early reception time of the target SPS PDSCH, and a magnitude of a serving cell index in which the target SPS PDSCH is located.

[0089] Specifically, the terminal may generate the first HARQ-ACK codebook in the order of the smallest allocation index corresponding to the SPS PDSCH, the earliest SPS PDSCH receiving time, or the smallest PDSCH serving cell index.

[0090] In method 2, when the multiple target SPS PDSCHs include an SPS group common PDSCH and an SPS unicast PDSCH, a first HARQ-ACK codebook corresponding to the SPS group common PDSCH and a second HARQ-ACK codebook corresponding to the SPS unicast PDSCH are separately generated, and the first HARQ-ACK codebook and the second HARQ-ACK codebook are cascaded to obtain a first target codebook.

[0091] Specifically, the terminal may separately generate HARQ-ACK codebooks corresponding to the SPS group-common PDSCH and the SPS unicast PDSCH, and cascade the two, where the HARQ-ACK codebook of the SPS group-common PDSCH may be placed after or before the HARQ-ACK codebook of the SPS unicast PDSCH when cascading, and is not limited thereto.

[0092] In addition, according to the codebook generation method provided in the above-mentioned method 1 and / or method 2, when the terminal needs to feed back the first target codebook and the second target codebook in the same time unit, the second target codebook is cascaded before the first target codebook, and the second target codebook is a HARQ-ACK codebook (codebook, CB) corresponding to a dynamically scheduled (DG) PDSCH.

[0093] Specifically, when it is necessary to feed back HARQ-ACK of a dynamically scheduled PDSCH, one or more SPS group-common PDSCHs, and one or more SPS unicast PDSCHs in one time unit, the terminal may first generate a first HARQ-ACK codebook corresponding to the SPS PDSCH part in the above-mentioned manner 1 and / or manner 2, and cascade the first HARQ-ACK codebook after the second HARQ-ACK codebook corresponding to the dynamically scheduled PDSCHs.

[0094] For ease of understanding, the above cascading situation of the first HARQ-ACK codebook and the second HARQ-ACK codebook will be further described below with reference to a different example.

[0095] (1) When the second HARQ-ACK codebook includes a unicast DG HARQ-ACK and the first HARQ-ACK codebook includes an SPS group-common HARQ-ACK (i.e., an HARQ-ACK corresponding to an SPS group-common PDSCH), or when the second HARQ-ACK codebook includes a group-common DG HARQ-ACK and the first HARQ-ACK codebook includes an SPS group-common HARQ-ACK, the first HARQ-ACK codebook may be cascaded after the second HARQ-ACK codebook.

[0096] (2) When the second HARQ-ACK codebook includes unicast DG HARQ-ACK and the first HARQ-ACK codebook includes SPS group-common HARQ-ACK+SPS unicast HARQ-ACK, or when the second HARQ-ACK codebook includes group-common DG HARQ-ACK and the first HARQ-ACK codebook includes SPS group-common HARQ-ACK+SPS unicast HARQ-ACK, the first HARQ-ACK codebook may be generated in scheme 1 or scheme 2, and the first HARQ-ACK codebook may be cascaded after the second HARQ-ACK codebook.

[0097] (3) When the second HARQ-ACK codebook includes unicast DG HARQ-ACK+group-common DG HARQ-ACK and the first HARQ-ACK codebook includes SPS group-common HARQ-ACK+SPS unicast HARQ-ACK, If the first HARQ-ACK codebook is created by the method 1, the first HARQ-ACK codebook and the second HARQ-ACK codebook may be cascaded by the following method (3a) or (3b). (3a) unicast DG HARQ-ACK + group-common DG HARQ-ACK + 1st HARQ-ACK codebook. (3b) group-common DG HARQ-ACK + unicast DG HARQ-ACK + 1st HARQ-ACK codebook. When the first HARQ-ACK codebook is generated by the method 2, or when the SPS unicast HARQ-ACK and the SPS group-common HARQ-ACK included in the first HARQ-ACK codebook are generated separately, the first HARQ-ACK codebook and the second HARQ-ACK codebook are generated by the following method (3c), (3d), or (3e): or (3f) You can cascade it with (3c)unicast DG HARQ-ACK+ ​​group-common DG HARQ-ACK+ ​​SPS unicast HARQ-ACK+ ​​SPS group-common HARQ-ACK. (3d)unicast DG HARQ-ACK +SPS unicast HARQ-ACK + group-common DG HARQ-ACK+ ​​SPS group-common HARQ-ACK. (3e) group-common DG HARQ-ACK+unicast DG HARQ-ACK+ ​​SPS group-common HARQ-ACK +SPS unicast HARQ-ACK. (3f)group-common DG HARQ-ACK+ ​​SPS group-common HARQ-ACK + unicast DG HARQ-ACK +SPS unicast HARQ-ACK.

[0098] It should be explained that the group-common DG HARQ-ACK described in 3(a)-3(f) above is feedback information corresponding to a dynamically scheduled group common PDSCH, the unicast DG HARQ-ACK is feedback information corresponding to a dynamically scheduled unicast PDSCH, the SPS group-common HARQ-ACK is feedback information corresponding to an SPS group common PDSCH, and the SPS unicast HARQ-ACK is feedback information corresponding to an SPS unicast PDSCH.

[0099] In this embodiment, when it is necessary to feed back a HARQ-ACK corresponding to an SPS group-common PDSCH and a HARQ-ACK corresponding to an SPS unicast PDSCH in one time unit, the terminal can determine a codebook in a scheduled manner, thereby ensuring effective transmission of feedback information and improving wireless communication performance.

[0100] It should be noted that the execution body of the PUCCH resource determination method 200-400 provided in the embodiment of the present application may be a PUCCH resource determination device or a control module for executing the PUCCH resource determination method in the PUCCH resource determination device. In the embodiment of the present application, the PUCCH resource determination device provided in the embodiment of the present application is taken as an example that the PUCCH resource determination device executes the PUCCH resource determination method.

[0101] 5a shows a block diagram of a PUCCH resource determining apparatus 500 provided in an exemplary embodiment of the present application. The apparatus 500 may include a determining module 510 used for determining a first target PUCCH resource for transmitting feedback information corresponding to a target SPS PDSCH when multiple SPS PDSCHs are configured or activated and feedback information corresponding to at least one target SPS PDSCH among the multiple SPS PDSCHs needs to be fed back in the same time unit.

When the PDSCH is an SPS group common PDSCH, this is used in at least one of the steps of determining a second PUCCH resource for transmitting feedback information of an arbitrary SPS group common PDSCH in which a mode for feeding back only the HARQ-NACK is configured as the first target PUCCH resource.

[0107] Optionally, the first SPS PDSCH comprises an SPS group common PDSCH or an SPS unicast PDSCH, and the second SPS PDSCH comprises an SPS group common PDSCH.

[0108] Optionally, referring again to FIG. 5b, the apparatus 500 includes a third feedback module 540 used for performing any one of the following when at least one of the target SPS PDSCHs includes a third SPS PDSCH and a fourth SPS PDSCH and feedback information corresponding to the third SPS PDSCH and the fourth SPS PDSCH need to be fed back in the same time unit: feeding back feedback information corresponding to the fourth designated SPS PDSCH based on a first target PUCCH resource corresponding to a fourth designated SPS PDSCH, wherein the fourth designated SPS PDSCH is determined from the third SPS PDSCH and the fourth SPS PDSCH based on fourth information; and multiplexing and feeding back the feedback information corresponding to the third SPS PDSCH and the feedback information corresponding to the fourth SPS PDSCH, wherein the third SPS PDSCH is an SPS group common PDSCH and the fourth SPS PDSCH is an SPS unicast PDSCH.
