Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to a processing method of a HARQ-ACK codebook, a terminal and a network side device. BACKGROUND

[0002] In the current technology, in order to ensure that the terminal and the network on both sides fully understand the number of Hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook bits and feed back the HARQ-ACK information of all configured HARQ processes, a Type-3 codebook is introduced, which feeds back the HARQ-ACK information for each configured code word of all configured HARQ processes on all currently configured carriers of the terminal. For the deleted HARQ-ACK, a retransmission mechanism is introduced, that is, an enhanced Type-3 HARQ-ACK codebook and one-shot triggering of HARQ-ACK re-transmission.

[0003] For the enhanced Type-3 HARQ-ACK codebook, only the HARQ-ACK corresponding to a carrier (CC) or a subset of HARQ processes can be reported, so that the HARQ-ACK corresponding to a certain subset can be triggered according to the need, and thus a smaller codebook size can be used to match the required HARQ-ACK information for retransmission. Considering that the required subset is different under different conditions, the network can pre-configure a codebook or a state list, each codebook or state in the list corresponding to a (different) subset (corresponding to a single enhanced Type-3 HARQ-ACK codebook), and the network can select the most matched subset according to the need and trigger the corresponding codebook or state. At present, the maximum number of enhanced Type-3 HARQ-ACK codebooks that can be supported by the terminal is 8.

[0004] The main idea behind one-shot triggering of HARQ-ACK re-transmission is to trigger the retransmission of a deleted HARQ-ACK codebook within a specific uplink time slot or sub-slot. A triggering downlink control information (DCI) instructs a new Physical Uplink Control Channel (PUCCH) resource within the uplink time slot or sub-slot to retransmit the deleted HARQ-ACK codebook intact. Each DCI can only trigger the retransmission of a single HARQ-ACK codebook. Only a single HARQ-ACK codebook can be retransmitted within a single new uplink time slot or sub-slot. If an initial HARQ-ACK transmission (corresponding to the same physical layer priority) still exists within the new uplink time slot or sub-slot, the retransmitted HARQ-ACK codebook is concatenated after the HARQ-ACK codebook corresponding to the initial transmission.

[0005] When the enhanced Type-3 codebook or Type-3 codebook that triggers the transmission corresponds to a different physical priority (PHY priority) than the initial HARQ-ACK codebook, the special attributes of the Type-3 codebook or enhanced Type-3 codebook are not taken into account. This may lead to unnecessary HARQ-ACK information transmission, reducing HARQ-ACK transmission efficiency (when PUCCH resources are not limited and the code rate can be guaranteed) or reliability (when PUCCH resources are limited and only the code rate can be increased).

Alternatively, the terminal does not expect the first and second HARQ-ACK codebooks to overlap, thereby reducing the implementation complexity of the terminal. Attached Figure Description

[0063] The following description, in conjunction with the accompanying drawings, details the processing method, terminal, and network-side equipment of the HARQ-ACK codebook provided in this application, through some embodiments and application scenarios.

[0064] like Figure 2 As shown in the embodiment of this application, a method for processing a HARQ-ACK codebook is provided, including:

[0065] Step 201: The terminal determines the first HARQ-ACK codebook and the second HARQ-ACK codebook to be transmitted. The priority of the first HARQ-ACK codebook is different from that of the second HARQ-ACK codebook.

[0066] The first HARQ-ACK codebook or the second HARQ-ACK codebook can be a type 1 codebook, a type 2 codebook, an enhanced type 2 codebook, a type 3 codebook, or an enhanced type 3 codebook, or other types of codebooks, without limitation. The first HARQ-ACK codebook or the second HARQ-ACK codebook can be a one-time triggered HARQ-ACK codebook, without limitation.

[0067] Step 202: If the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, the terminal performs the first operation; or, the terminal does not expect the first HARQ-ACK codebook and the second HARQ-ACK codebook to overlap.

[0068] The first operation includes any one of the following:

[0069] Discard the first HARQ-ACK codebook and transmit the second HARQ-ACK codebook;

[0070] Discard the first HARQ-ACK codebook contained in the second HARQ-ACK codebook, and transmit the second HARQ-ACK codebook;

[0071] The first HARQ-ACK codebook and the second HARQ-ACK codebook are multiplexed and transmitted on a Physical Uplink Control Channel (PUCCH) resource.

[0072] In at least one embodiment of this application, "the terminal does not expect the first HARQ-ACK codebook and the second HARQ-ACK codebook to overlap" can be understood as: the network-side device needs to ensure that the first HARQ-ACK codebook and the second HARQ-ACK codebook cannot be determined to overlap, otherwise the terminal cannot handle the scenario where the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, and treats this scenario as an error case. Optionally, the terminal can ignore the transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook at this time.

[0073] In at least one embodiment of this application, when the first HARQ-ACK codebook and the second HARQ-ACK codebook do not overlap, the terminal transmits the first HARQ-ACK codebook on the PUCCH resource corresponding to the first HARQ-ACK codebook and transmits the second HARQ-ACK codebook on the PUCCH resource corresponding to the second HARQ-ACK codebook.

[0074] For example, for at least two HARQ-ACK codebooks with different priorities that are triggered by a one-shot triggering of HARQ-ACK re-transmission (i.e., at least two retransmitted HARQ-ACK codebooks with different priorities), any of the following methods can be used:

[0075] The terminal does not expect at least two retransmitted HARQ-ACK codebooks to overlap;

[0076] At least two retransmission HARQ-ACK codebooks are allowed to overlap, and the first operation is performed.

[0077] It should be noted that, for a certain priority, when triggering more than one Type 3 HARQ-ACK codebook or an enhanced Type 3 HARQ-ACK codebook within a single PUCCH time unit (optionally, further feedback of the initial HARQ-ACK codebook is required within this PUCCH time unit), HARQ-ACK multiplexing or decision processing can be performed first for that priority to determine the single HARQ-ACK codebook that needs to be transmitted. Then, step 202 above is executed for the HARQ-ACK codebooks corresponding to different priorities (each priority corresponds to a single HARQ-ACK codebook). That is, when a priority corresponds to at least two HARQ-ACK codebooks, the method further includes:

[0078] The terminal determines a HARQ-ACK codebook to be transmitted corresponding to the given priority; the HARQ-ACK codebook to be transmitted is either the first HARQ-ACK codebook or the second HARQ-ACK codebook.

[0079] In at least one embodiment of this application, the method further includes:

[0080] If the first HARQ-ACK codebook and the second HARQ-ACK codebook satisfy a first condition, the terminal determines that the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap; wherein, the first condition includes any one of the following:

[0081] The PUCCH resources corresponding to the first HARQ-ACK codebook and the PUCCH resources corresponding to the second HARQ-ACK codebook have temporal overlap.

[0082] The time unit where the PUCCH resource corresponding to the first HARQ-ACK codebook is located overlaps with the time unit where the PUCCH resource corresponding to the second HARQ-ACK codebook is located in the time domain.

[0083] The PUCCH time unit associated with the PUCCH resource corresponding to the first HARQ-ACK codebook is the same PUCCH time unit as the PUCCH time unit associated with the PUCCH resource corresponding to the second HARQ-ACK codebook.

[0084] Optionally, the above-mentioned PUCCH time unit can be understood as: a time unit configured for PUCCH transmission, which can be configured as a time slot or a sub-slot. When configured as a sub-slot, it can also correspond to different numbers of symbols as needed, such as 2 symbols or 7 symbols.

[0085] Optionally, the PUCCH time unit where the PUCCH resource corresponding to the first HARQ-ACK codebook is located can be determined based on the PUCCH configuration of the corresponding priority, and the PUCCH time unit where the PUCCH resource corresponding to the second HARQ-ACK codebook is located can be determined based on the PUCCH configuration of the corresponding priority.

[0086] Optionally, the PUCCH resource corresponding to the HARQ-ACK codebook can be understood as: the PUCCH resource that carries this HARQ-ACK codebook.

[0087] Optionally, the PUCCH time unit associated with the PUCCH resource corresponding to the first HARQ-ACK codebook is the n1th first PUCCH time unit among one or more first PUCCH time units that have time domain overlap with the PUCCH resource corresponding to the first HARQ-ACK codebook, where n1 is a pre-agreed or network-configured value.

[0088] The PUCCH time unit associated with the PUCCH resource corresponding to the second HARQ-ACK codebook is the n2th first PUCCH time unit among one or more first PUCCH time units that have time domain overlap with the PUCCH resource corresponding to the second HARQ-ACK codebook, where n2 is a pre-agreed or network-configured value; optionally, the values ​​of n1 and n2 can be the same.

[0089] The first PUCCH time unit is a PUCCH time unit corresponding to a first preset priority. For example, the first PUCCH time unit is a single PUCCH time unit corresponding to a high priority, or a single PUCCH time unit corresponding to a low priority.

[0090] For example, the n1th first PUCCH time unit is either the first or the last first PUCCH time unit among one or more first PUCCH time units that have temporal overlap with the PUCCH resources corresponding to the first HARQ-ACK codebook. The n2th first PUCCH time unit is either the first or the last first PUCCH time unit among one or more first PUCCH time units that have temporal overlap with the PUCCH resources corresponding to the second HARQ-ACK codebook.

[0091] like Figure 3 As shown, the first HARQ-ACK codebook corresponds to the high priority, and the PUCCH resource corresponding to the first HARQ-ACK codebook is located in PUCCH slot 2 corresponding to the high priority; the second HARQ-ACK codebook corresponds to the low priority, and the PUCCH resource corresponding to the second HARQ-ACK codebook is located in PUCCH slot 1 corresponding to the low priority.

[0092] exist Figure 3 In the first HARQ-ACK codebook, the PUCCH resources corresponding to the first HARQ-ACK codebook and the PUCCH resources corresponding to the second HARQ-ACK codebook do not overlap in the time domain.

[0093] exist Figure 3In the PUCCH time slot 2, where the PUCCH resource corresponding to the first HARQ-ACK codebook is located, there is a temporal overlap with the PUCCH time slot 1, where the PUCCH resource corresponding to the second HARQ-ACK codebook is located.

[0094] exist Figure 3 In the above, when the first preset priority is high priority, and the PUCCH time unit associated with a certain PUCCH resource is the first or earliest first PUCCH time unit among one or more first PUCCH time units that overlap with the PUCCH resource in the time domain, the PUCCH time unit associated with the PUCCH resource corresponding to the first HARQ-ACK codebook is PUCCH slot 2 corresponding to the high priority, and the PUCCH time unit associated with the PUCCH resource corresponding to the second HARQ-ACK codebook is PUCCH slot 2 corresponding to the high priority, that is, they are the same PUCCH time unit.

[0095] The PUCCH time unit associated with the PUCCH resource corresponding to the first HARQ-ACK codebook is the same PUCCH time unit as the PUCCH time unit associated with the PUCCH resource corresponding to the second HARQ-ACK codebook.

[0096] In an optional embodiment of this application, when the first operation is to discard the first HARQ-ACK codebook and transmit the second HARQ-ACK codebook, the first HARQ-ACK codebook and the second HARQ-ACK codebook satisfy any one of the following conditions:

[0097] The priority of the first HARQ-ACK codebook is lower than that of the second HARQ-ACK codebook, which can be understood as: discarding the HARQ-ACK codebook corresponding to the lower priority;

[0098] The first HARQ-ACK codebook is a Type-1 codebook, a Type-2 codebook, or an enhanced Type-2 codebook, and the second HARQ-ACK codebook is a Type-3 codebook or an enhanced Type-3 codebook. This can be understood as discarding the Type-1 codebook, the Type-2 codebook, or the enhanced Type-2 codebook.

[0099] When the first HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, and the second HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, the number of HARQ processes corresponding to the first HARQ-ACK codebook is less than or equal to the number of HARQ processes corresponding to the second HARQ-ACK codebook. This can be understood as follows: when both HARQ-ACK codebooks correspond to Type 3 codebooks or enhanced Type 3 codebooks, the HARQ-ACK codebook with the smaller number of HARQ processes is discarded.

[0100] Optionally, the HARQ process involved in a certain Type-3 codebook or enhanced Type-3 codebook can be determined by the set of serving cells configured for this codebook and / or the set of HARQ processes configured for each serving cell.

[0101] In another optional embodiment of this application, when the first operation includes: discarding the first HARQ-ACK codebook contained in the second HARQ-ACK codebook and transmitting the second HARQ-ACK codebook, the first HARQ-ACK codebook and the second HARQ-ACK codebook satisfy at least one of the following conditions:

[0102] The first HARQ-ACK codebook is a type 1 codebook, a type 2 codebook, or an enhanced type 2 codebook, and the second HARQ-ACK codebook is a type 3 codebook or an enhanced type 3 codebook. This can be understood as follows: when one HARQ-ACK codebook is a type 1 codebook, a type 2 codebook, or an enhanced type 2 codebook, and the other HARQ-ACK codebook is a type 3 codebook or an enhanced type 3 codebook, it is required that the HARQ processes corresponding to the type 1 codebook, type 2 codebook, or enhanced type 2 codebook are all included in the type 3 codebook or enhanced type 3 codebook. At this time, only the type 3 codebook or enhanced type 3 codebook is transmitted.

[0103] The first HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, and the second HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook. This can be understood as follows: when both HARQ-ACK codebooks correspond to a Type 3 codebook or an enhanced Type 3 codebook, it is required that the HARQ-ACK process corresponding to one of the codebooks is included in the HARQ process corresponding to the other codebook. In this case, only the transmission of the other HARQ-ACK codebook is performed.

[0104] The aforementioned requirement that "the HARQ processes corresponding to Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook are all included in Type 3 codebook or enhanced Type 3 codebook" or "the HARQ-ACK process corresponding to one codebook is included in the HARQ process corresponding to another codebook" can be understood as follows: when configuring or instructing the UE to report the HARQ-ACK codebook, the network side requires that the corresponding conditions be met. In other words, the UE expects the HARQ-ACK codebook that is configured or instructed to be reported to meet the corresponding conditions; otherwise, the UE considers it an error case or cannot process it.

[0105] In another optional embodiment of this application, when the first operation includes: discarding the first HARQ-ACK codebook contained in the second HARQ-ACK codebook and transmitting the second HARQ-ACK codebook, the first HARQ-ACK codebook and the second HARQ-ACK codebook satisfy at least one of the following conditions:

[0106] When the set of HARQ processes corresponding to the first HARQ-ACK codebook is the same as the set of HARQ processes corresponding to the second HARQ-ACK codebook, the second HARQ-ACK codebook corresponds to the second preset priority. This can be understood as transmitting the HARQ-ACK codebook corresponding to the second preset priority (i.e., the specified priority) in this scenario.

[0107] or,

[0108] When the set of HARQ processes corresponding to the first HARQ-ACK codebook is different from the set of HARQ processes corresponding to the second HARQ-ACK codebook, the priority of the second HARQ-ACK codebook is higher than the priority of the first HARQ-ACK codebook. This can be understood as requiring the second HARQ-ACK codebook to correspond to a higher priority in actual transmission. When the codebook to be transmitted corresponds to a higher priority, its transmission performance can be better guaranteed.

[0109] Optionally, when the set of HARQ processes corresponding to the first HARQ-ACK codebook is different from the set of HARQ processes corresponding to the second HARQ-ACK codebook, no additional requirements are made on the priority corresponding to the second HARQ-ACK codebook and the priority corresponding to the first HARQ-ACK codebook.

[0110] In another optional embodiment of this application, when the first operation includes: multiplexing the transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook on a PUCCH resource, the first HARQ-ACK codebook and the second HARQ-ACK codebook satisfy the following conditions:

[0111] The first HARQ-ACK codebook is a type 1 codebook, a type 2 codebook, an enhanced type 2 codebook, a type 3 codebook, or an enhanced type 3 codebook, and the second HARQ-ACK codebook is a type 1 codebook, a type 2 codebook, an enhanced type 2 codebook, a type 3 codebook, or an enhanced type 3 codebook. This can be understood as: under this operation, there is no limitation on the type of the first HARQ-ACK codebook or the type of the second HARQ-ACK codebook.

[0112] It should be noted that the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook includes at least one of the following:

[0113] Initial semi-persistent scheduling of SPS HARQ-ACK information bits;

[0114] Delayed semi-persistent scheduling (SPS) HARQ-ACK information bits.

[0115] At least one type 1 codebook or type 2 codebook or enhanced type 2 codebook.

[0116] For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook mentioned in the embodiments of this application is composed of a single Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook. For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook mentioned in the embodiments of this application includes a HARQ-ACK bit sequence determined based on a first predefined pseudocode (at least one HARQ-ACK bit in the output HARQ-ACK bit sequence corresponds to a dynamically scheduled Physical Downlink Shared Channel (PDSCH)), and / or a HARQ-ACK bit sequence determined based on a second predefined pseudocode (each HARQ-ACK bit in the output HARQ-ACK bit sequence corresponds to an SPS PDSCH).

[0117] For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook provided in this application embodiment is formed by concatenating at least two Type 1 codebooks, Type 2 codebooks, or enhanced Type 2 codebooks in a predefined order. For instance, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook provided in this application embodiment is formed by concatenating two Type 1 codebooks, Type 2 codebooks, or enhanced Type 2 codebooks in a predefined order, where one codebook corresponds to the initial transmission HARQ-ACK, and the other codebook corresponds to the retransmission HARQ-ACK. This retransmission is triggered by a one-shot triggering of HARQ-ACK re-transmission mechanism, in which case the retransmitted codebook is concatenated after the initial transmission codebook.

[0118] For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook provided in this application embodiment is formed by concatenating a single Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook with the initial SPS HARQ-ACK information bits in a predefined order.

[0119] For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook provided in this application embodiment is formed by concatenating a single Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook with delayed SPS HARQ-ACK information bits in a predefined order.

[0120] For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook provided in this application embodiment is formed by concatenating a single Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook, initial SPS HARQ-ACK information, and delayed SPS HARQ-ACK information bits in a predefined order.

[0121] In at least one embodiment of this application, the method further includes:

[0122] The terminal determines the PUCCH resources used for transmitting the second HARQ-ACK codebook according to a first method; the first method includes any one of the following:

[0123] Use the PUCCH resource corresponding to the second HARQ-ACK codebook; wherein, the priority corresponding to the second HARQ-ACK codebook remains unchanged;

[0124] Use the PUCCH resource corresponding to the first target priority.

[0125] Wherein, if the priority of the first target is different from the priority corresponding to the second HARQ-ACK codebook, the method further includes:

[0126] The terminal determines the PUCCH resource corresponding to the first target priority based on the number of bits corresponding to the second HARQ-ACK codebook. For example, it first determines a set of PUCCH resources corresponding to a predefined first target priority based on the number of bits, and then determines a single PUCCH resource from the set of PUCCH resources based on the PUCCH resource index PRI.

[0127] Optionally, the first target priority mentioned above can be specified by the protocol or configured by higher-level parameters, for example, the first target priority can be set to high priority.

[0128] In at least one embodiment of this application, when the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, the terminal can directly execute the first operation, or the specific content of the first operation can be determined before executing the first operation. That is, before the terminal executes the first operation, the method further includes:

[0129] The terminal determines whether all the HARQ-ACK information corresponding to the first HARQ-ACK codebook is included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook;

[0130] When the HARQ-ACK information corresponding to the first HARQ-ACK codebook is all included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook, the terminal determines that the first operation is: discarding the first HARQ-ACK codebook contained in the second HARQ-ACK codebook and transmitting the second HARQ-ACK codebook;

[0131] If the HARQ-ACK information corresponding to the first HARQ-ACK codebook is not all included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook, the terminal determines that the first operation is: multiplexing the transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook on a PUCCH resource.

[0132] It should be noted that "whether the HARQ-ACK information corresponding to the first HARQ-ACK codebook is all included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook" can be understood as: whether the HARQ processes corresponding to the first HARQ-ACK codebook are all mapped to the HARQ processes corresponding to the second HARQ-ACK codebook, or in other words, whether any PDSCH or HARQ process involved in the first HARQ-ACK codebook is included in the PDSCH set or HARQ process set corresponding to the second HARQ-ACK codebook. The statement “The HARQ-ACK information corresponding to the first HARQ-ACK codebook is not all included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook” can be understood as: at least one PDSCH or HARQ process corresponding to the HARQ-ACK information in the first HARQ-ACK codebook is not included in the HARQ-ACK information in the second HARQ-ACK codebook, or in other words, at least one PDSCH or HARQ process involved in the first HARQ-ACK codebook is not included in the PDSCH set or HARQ process set corresponding to the second HARQ-ACK codebook.

[0133] Optionally, when the first HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, and the second HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, the terminal determines whether all the HARQ-ACK information corresponding to the first HARQ-ACK codebook is included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook. This can avoid inconsistencies between the terminal and the network-side device in their understanding of the actual transmitted codebook (including the length of the HARQ-ACK bit sequence, and the meaning of each HARQ-ACK bit or its correspondence with the PDSCH / HARQ process).

[0134] As an optional embodiment, multiplexing the transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook on a single PUCCH resource includes:

[0135] The first HARQ-ACK codebook and the second HARQ-ACK codebook are concatenated end to end to form the HARQ-ACK bit sequence. The concatenated HARQ-ACK bit sequence is then uniformly encoded and mapped to the first PUCCH resource corresponding to the second target priority for transmission.

[0136] For example, when performing head-to-tail concatenation, the HARQ-ACK bit sequence corresponding to the lower-priority HARQ-ACK codebook can be concatenated after the HARQ-ACK bit sequence corresponding to the higher-priority HARQ-ACK codebook, or vice versa. The concatenated HARQ-ACK bit sequence is then uniformly encoded and mapped to a single PUCCH resource (i.e., the first PUCCH resource).

[0137] Optionally, the method further includes:

[0138] The terminal determines the first PUCCH resource corresponding to the second target priority based on the number of bits corresponding to the concatenated HARQ-ACK bit sequence.

[0139] The first PUCCH resource can be determined using the PUCCH resources corresponding to the predefined second target priority, based on the number of bits in the concatenated HARQ-ACK bit sequence and predefined rules. For example, first, a set of PUCCH resources corresponding to the second target priority is determined based on the number of bits, and then a single PUCCH resource is determined from that set of PUCCH resources based on the PUCCH resource index PRI.

[0140] Optionally, the aforementioned second target priority can be specified by the protocol or configured by higher-level parameters, for example, the second target priority can be a high priority. The PRI of the aforementioned first PUCCH resource can be the PRI of the codebook participating in the multiplexing that corresponds to the second target priority.

[0141] Alternatively, multiplexing the transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook on a single PUCCH resource includes:

[0142] The first HARQ-ACK codebook and the second HARQ-ACK codebook are encoded respectively and mapped to the second PUCCH resource corresponding to the third target priority for transmission.

[0143] Optionally, the method further includes:

[0144] The terminal determines the second PUCCH resource corresponding to the third target priority based on the sum of the number of bits corresponding to the first HARQ-ACK codebook and the number of bits corresponding to the second HARQ-ACK codebook.

[0145] The second PUCCH resource can use PUCCH resources corresponding to a predefined third target priority. The PUCCH resource corresponding to the third target priority is determined based on the sum of the number of bits corresponding to the first HARQ-ACK codebook and the second HARQ-ACK codebook, along with predefined rules. For example, first, a set of PUCCH resources corresponding to the third target priority is determined based on the sum of the number of bits, and then a single PUCCH resource is determined from this set based on the PUCCH resource index PRI.

[0146] Optionally, the aforementioned third target priority can be specified by the protocol or configured by higher-level parameters, for example, the third target priority can be set to high priority. The PRI of the aforementioned second PUCCH resource can be the PRI of the codebook participating in the multiplexing that corresponds to the third target priority.

[0147] In at least one embodiment of this application, before multiplexing the transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook on a PUCCH resource, the method further includes:

[0148] The terminal determines whether there is redundancy between the HARQ-ACK information corresponding to the first HARQ-ACK codebook and the HARQ-ACK information corresponding to the second HARQ-ACK codebook;

[0149] If redundancy is determined to exist, the terminal deletes redundant HARQ-ACK bits from the first HARQ-ACK codebook, or the terminal deletes redundant HARQ-ACK bits from the second HARQ-ACK codebook.

[0150] It should be noted that the "HARQ-ACK information corresponding to the HARQ-ACK codebook" mentioned above can be understood as: the HARQ-ACK information corresponding to each PDSCH or HARQ process in the PDSCH set or HARQ process set corresponding to the HARQ-ACK codebook.

[0151] Optionally, if the HARQ process corresponding to the first HARQ-ACK codebook can be mapped (including partial and complete mapping) to the HARQ process corresponding to the second HARQ-ACK codebook, redundancy is determined, and redundant HARQ-ACK bits can be further identified. The determination of redundant HARQ-ACK bits can be as follows: if a certain HARQ-ACK bit in the first HARQ-ACK codebook and a certain HARQ-ACK bit in the second HARQ-ACK codebook correspond to the same HARQ process, then this HARQ-ACK bit in the first HARQ-ACK codebook and this HARQ-ACK bit in the second HARQ-ACK codebook are considered redundant HARQ-ACK bits.

[0152] For example, when two HARQ-ACK codebooks are concatenated end-to-end, redundant HARQ-ACK bits in either the first or second HARQ-ACK codebook can be deleted, and the processing attributes of the two codebooks are actually the same.

[0153] For example, when HARQ-ACK codebooks are encoded separately, redundant HARQ-ACK bits in the lower-priority HARQ-ACK codebooks can be removed. In this case, the redundant HARQ-ACK bits are transmitted only once in the higher-priority HARQ-ACK codebook, and are not transmitted in the lower-priority HARQ-ACK codebook, thus ensuring the transmission performance of this part of the HARQ-ACK information.

[0154] The above-mentioned removal of redundant HARQ-ACK bits from a certain HARQ-ACK codebook can be understood as removing the redundant HARQ-ACK bits from the corresponding HARQ-ACK bit sequence in the codebook, and concatenating the remaining HARQ-ACK bits in the codebook based on their relative order.

[0155] Optionally, when the first HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, and the second HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, the terminal determines whether there is redundancy between the HARQ-ACK information corresponding to the first HARQ-ACK codebook and the HARQ-ACK information corresponding to the second HARQ-ACK codebook, which can avoid inconsistencies between the terminal and the network-side device in their understanding of the codebook actually transmitted.

[0156] Accordingly, the multiplexing of the first HARQ-ACK codebook and the second HARQ-ACK codebook on a PUCCH resource includes:

[0157] The first HARQ-ACK codebook after removing redundant HARQ-ACK bits and the second HARQ-ACK codebook are concatenated end to end of the HARQ-ACK bit sequence. The concatenated HARQ-ACK bit sequence is then uniformly encoded and mapped to the third PUCCH resource corresponding to the fourth target priority for transmission.

[0158] Furthermore, the method also includes:

[0159] The terminal determines the third PUCCH resource corresponding to the fourth target priority based on the number of bits corresponding to the concatenated HARQ-ACK bit sequence.

[0160] Alternatively, the multiplexing of the first HARQ-ACK codebook and the second HARQ-ACK codebook on a PUCCH resource includes:

[0161] The first HARQ-ACK codebook and the second HARQ-ACK codebook after removing redundant HARQ-ACK bits are concatenated end to end of the HARQ-ACK bit sequence. The concatenated HARQ-ACK bit sequence is then uniformly encoded and mapped to the fourth PUCCH resource corresponding to the fifth target priority for transmission.

[0162] Furthermore, the method also includes:

[0163] The terminal determines the fourth PUCCH resource corresponding to the fifth target priority based on the number of bits corresponding to the concatenated HARQ-ACK bit sequence.

[0164] Alternatively, the multiplexing of the first HARQ-ACK codebook and the second HARQ-ACK codebook on a PUCCH resource includes:

[0165] The first HARQ-ACK codebook and the second HARQ-ACK codebook, after removing redundant HARQ-ACK bits, are encoded respectively and mapped to the fifth PUCCH resource corresponding to the sixth target priority for transmission.

[0166] Furthermore, the method also includes:

[0167] The terminal determines the fifth PUCCH resource corresponding to the sixth target priority based on the sum of the number of bits corresponding to the first HARQ-ACK codebook after deleting redundant HARQ-ACK bits and the number of bits corresponding to the second HARQ-ACK codebook.

[0168] Alternatively, the multiplexing of the first HARQ-ACK codebook and the second HARQ-ACK codebook on a PUCCH resource includes:

[0169] The first HARQ-ACK codebook and the second HARQ-ACK codebook after removing redundant HARQ-ACK bits are encoded respectively and mapped to the sixth PUCCH resource corresponding to the seventh target priority for transmission.

[0170] Furthermore, the method also includes:

[0171] The terminal determines the sixth PUCCH resource corresponding to the seventh target priority based on the sum of the number of bits corresponding to the first HARQ-ACK codebook and the number of bits corresponding to the second HARQ-ACK codebook after deleting redundant HARQ-ACK bits.

[0172] In summary, in the embodiments of this application, for first HARQ-ACK codebooks and second HARQ-ACK codebooks with different priorities, when the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, the terminal transmits only one HARQ-ACK codebook or reuses the transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook on one PUCCH resource, thereby avoiding redundant HARQ-ACK information transmission and improving HARQ-ACK transmission efficiency or transmission reliability. Alternatively, the terminal does not expect the first HARQ-ACK codebook and the second HARQ-ACK codebook to overlap, thereby reducing the implementation complexity of the terminal.

[0173] like Figure 4 As shown in the embodiments of this application, a method for processing a HARQ-ACK codebook is also provided, including:

[0174] Step 301: The network-side device configures or instructs the terminal to transmit a first HARQ-ACK codebook and a second HARQ-ACK codebook, wherein the priority of the first HARQ-ACK codebook is different from the priority of the second HARQ-ACK codebook.

[0175] In this step, "configuration" can be understood as configuration based on higher-level signaling; "indication" can be understood as dynamic indication or triggering based on downlink control information (DCI).

[0176] The first HARQ-ACK codebook or the second HARQ-ACK codebook can be a type 1 codebook, a type 2 codebook, an enhanced type 2 codebook, a type 3 codebook, or an enhanced type 3 codebook, or other types of codebooks, without limitation. The first HARQ-ACK codebook or the second HARQ-ACK codebook can be a one-time triggered HARQ-ACK codebook, without limitation.

[0177] Step 302: If the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, the network-side device performs the second operation; or, the network-side device ensures that the first HARQ-ACK codebook and the second HARQ-ACK codebook do not overlap.

[0178] The second operation includes any one of the following:

[0179] Abandon receiving the first HARQ-ACK codebook and receive the second HARQ-ACK codebook;

[0180] Abandon receiving the first HARQ-ACK codebook contained in the second HARQ-ACK codebook, and receive the second HARQ-ACK codebook;

[0181] The first HARQ-ACK codebook and the second HARQ-ACK codebook are received on a Physical Uplink Control Channel (PUCCH) resource.

[0182] In at least one embodiment of this application, the network-side device needs to ensure that the first HARQ-ACK codebook and the second HARQ-ACK codebook cannot be determined to overlap. Otherwise, the terminal cannot handle the scenario where the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, and treats this scenario as an error case. Optionally, the terminal can ignore the transmission of the first HARQ-ACK codebook and the second HARQ-ACK codebook at this time.

[0183] In at least one embodiment of this application, the method further includes:

[0184] If the first HARQ-ACK codebook and the second HARQ-ACK codebook satisfy a first condition, the network-side device determines that the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap; wherein, the first condition includes any one of the following:

[0185] The PUCCH resources corresponding to the first HARQ-ACK codebook and the PUCCH resources corresponding to the second HARQ-ACK codebook have temporal overlap.

[0186] The time unit where the PUCCH resource corresponding to the first HARQ-ACK codebook is located overlaps with the time unit where the PUCCH resource corresponding to the second HARQ-ACK codebook is located in the time domain.

[0187] The PUCCH time unit associated with the PUCCH resource corresponding to the first HARQ-ACK codebook is the same PUCCH time unit as the PUCCH time unit associated with the PUCCH resource corresponding to the second HARQ-ACK codebook.

[0188] Optionally, the above-mentioned PUCCH time unit can be understood as: a time unit configured for PUCCH transmission, which can be configured as a time slot or a sub-slot. When configured as a sub-slot, it can also correspond to different numbers of symbols as needed, such as 2 symbols or 7 symbols.

[0189] Optionally, the PUCCH time unit where the PUCCH resource corresponding to the first HARQ-ACK codebook is located can be determined based on the PUCCH configuration of the corresponding priority, and the PUCCH time unit where the PUCCH resource corresponding to the second HARQ-ACK codebook is located can be determined based on the PUCCH configuration of the corresponding priority.

[0190] Optionally, the PUCCH resource corresponding to the HARQ-ACK codebook can be understood as: the PUCCH resource that carries this HARQ-ACK codebook.

[0191] Optionally, the PUCCH time unit associated with the PUCCH resource corresponding to the first HARQ-ACK codebook is the n1th first PUCCH time unit among one or more first PUCCH time units that have time domain overlap with the PUCCH resource corresponding to the first HARQ-ACK codebook, where n1 is a pre-agreed or network-configured value.

[0192] The PUCCH time unit associated with the PUCCH resource corresponding to the second HARQ-ACK codebook is the n2th first PUCCH time unit among one or more first PUCCH time units that have time domain overlap with the PUCCH resource corresponding to the second HARQ-ACK codebook, where n2 is a pre-agreed or network-configured value.

[0193] The first PUCCH time unit is a PUCCH time unit corresponding to a first preset priority. For example, the first PUCCH time unit is a single PUCCH time unit corresponding to a high priority, or a single PUCCH time unit corresponding to a low priority.

[0194] For example, the n1st first PUCCH time unit is either the first first PUCCH time unit or the last first PUCCH time unit among one or more first PUCCH time units that have time-domain overlap with the PUCCH resources corresponding to the first HARQ-ACK codebook.

[0195] In an optional embodiment of this application, when the second operation is to abandon the reception of the first HARQ-ACK codebook and receive the second HARQ-ACK codebook, the first HARQ-ACK codebook and the second HARQ-ACK codebook satisfy any one of the following conditions:

[0196] The priority of the first HARQ-ACK codebook is lower than that of the second HARQ-ACK codebook, which can be understood as: discarding the HARQ-ACK codebook corresponding to the lower priority;

[0197] The first HARQ-ACK codebook is a type 1 codebook, a type 2 codebook, or an enhanced type 2 codebook, and the second HARQ-ACK codebook is a type 3 codebook or an enhanced type 3 codebook. This can be understood as: discarding the type 1 codebook, the type 2 codebook, or the enhanced type 2 codebook.

[0198] When the first HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, and the second HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, the number of HARQ processes corresponding to the first HARQ-ACK codebook is less than or equal to the number of HARQ processes corresponding to the second HARQ-ACK codebook. This can be understood as follows: when both HARQ-ACK codebooks correspond to Type 3 codebooks or enhanced Type 3 codebooks, the HARQ-ACK codebook with the smaller number of HARQ processes is discarded.

[0199] Optionally, the HARQ process involved in a certain Type-3 codebook or enhanced Type-3 codebook can be determined by the set of serving cells configured for this codebook and / or the set of HARQ processes configured for each serving cell.

[0200] In another optional embodiment of this application, when the second operation includes: abandoning the reception of the first HARQ-ACK codebook contained in the second HARQ-ACK codebook, and receiving the second HARQ-ACK codebook, the first HARQ-ACK codebook and the second HARQ-ACK codebook satisfy at least one of the following conditions:

[0201] The first HARQ-ACK codebook is a type 1 codebook, a type 2 codebook, or an enhanced type 2 codebook, and the second HARQ-ACK codebook is a type 3 codebook or an enhanced type 3 codebook. This can be understood as follows: when one HARQ-ACK codebook is a type 1 codebook, a type 2 codebook, or an enhanced type 2 codebook, and the other HARQ-ACK codebook is a type 3 codebook or an enhanced type 3 codebook, it is required that the HARQ processes corresponding to the type 1 codebook, type 2 codebook, or enhanced type 2 codebook are all included in the type 3 codebook or enhanced type 3 codebook. At this time, only the type 3 codebook or enhanced type 3 codebook is transmitted.

[0202] The first HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, and the second HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook. This can be understood as follows: when both HARQ-ACK codebooks correspond to a Type 3 codebook or an enhanced Type 3 codebook, it is required that the HARQ-ACK process corresponding to one of the codebooks is included in the HARQ process corresponding to the other codebook. In this case, only the transmission of the other HARQ-ACK codebook is performed.

[0203] The aforementioned requirement that "the HARQ processes corresponding to Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook are all included in Type 3 codebook or enhanced Type 3 codebook" or "the HARQ-ACK process corresponding to one codebook is included in the HARQ process corresponding to another codebook" can be understood as follows: when configuring or instructing the UE to report the HARQ-ACK codebook, the network side requires that the corresponding conditions be met. In other words, the UE expects the HARQ-ACK codebook that is configured or instructed to be reported to meet the corresponding conditions; otherwise, the UE considers it an error case or cannot process it.

[0204] In another optional embodiment of this application, when the second operation includes: abandoning the reception of the first HARQ-ACK codebook contained in the second HARQ-ACK codebook, and receiving the second HARQ-ACK codebook, the first HARQ-ACK codebook and the second HARQ-ACK codebook satisfy at least one of the following conditions:

[0205] When the set of HARQ processes corresponding to the first HARQ-ACK codebook is the same as the set of HARQ processes corresponding to the second HARQ-ACK codebook, the second HARQ-ACK codebook corresponds to the second preset priority. This can be understood as transmitting the HARQ-ACK codebook corresponding to the second preset priority (i.e., the specified priority) in this scenario.

[0206] or,

[0207] When the set of HARQ processes corresponding to the first HARQ-ACK codebook is different from the set of HARQ processes corresponding to the second HARQ-ACK codebook, the priority of the second HARQ-ACK codebook is higher than the priority of the first HARQ-ACK codebook. This can be understood as requiring the second HARQ-ACK codebook to correspond to a higher priority in actual transmission. When the codebook to be transmitted corresponds to a higher priority, its transmission performance can be better guaranteed.

[0208] Optionally, when the set of HARQ processes corresponding to the first HARQ-ACK codebook is different from the set of HARQ processes corresponding to the second HARQ-ACK codebook, no additional requirements are made on the priority corresponding to the second HARQ-ACK codebook and the priority corresponding to the first HARQ-ACK codebook.

[0209] In another optional embodiment of this application, when the second operation includes receiving the first HARQ-ACK codebook and the second HARQ-ACK codebook on a PUCCH resource, the first HARQ-ACK codebook and the second HARQ-ACK codebook satisfy the following conditions:

[0210] The first HARQ-ACK codebook is a type 1 codebook, a type 2 codebook, an enhanced type 2 codebook, a type 3 codebook, or an enhanced type 3 codebook, and the second HARQ-ACK codebook is a type 1 codebook, a type 2 codebook, an enhanced type 2 codebook, a type 3 codebook, or an enhanced type 3 codebook. This can be understood as: under this operation, there is no limitation on the type of the first HARQ-ACK codebook or the type of the second HARQ-ACK codebook.

[0211] It should be noted that the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook includes at least one of the following:

[0212] Initial semi-persistent scheduling of SPS HARQ-ACK information bits;

[0213] Delayed semi-persistent scheduling (SPS) HARQ-ACK information bits.

[0214] At least one type 1 codebook or type 2 codebook or enhanced type 2 codebook.

[0215] For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook mentioned in the embodiments of this application is composed of a single Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook. For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook mentioned in the embodiments of this application includes a HARQ-ACK bit sequence determined based on a first predefined pseudocode (at least one HARQ-ACK bit in the output HARQ-ACK bit sequence corresponds to a dynamically scheduled Physical Downlink Shared Channel (PDSCH)), and / or a HARQ-ACK bit sequence determined based on a second predefined pseudocode (each HARQ-ACK bit in the output HARQ-ACK bit sequence corresponds to an SPS PDSCH).

[0216] For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook provided in this application embodiment is formed by concatenating at least two Type 1 codebooks, Type 2 codebooks, or enhanced Type 2 codebooks in a predefined order. For instance, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook provided in this application embodiment is formed by concatenating two Type 1 codebooks, Type 2 codebooks, or enhanced Type 2 codebooks in a predefined order, where one codebook corresponds to the initial transmission HARQ-ACK, and the other codebook corresponds to the retransmission HARQ-ACK. This retransmission is triggered by a one-shot triggering of HARQ-ACK re-transmission mechanism, in which case the retransmitted codebook is concatenated after the initial transmission codebook.

[0217] For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook provided in this application embodiment is formed by concatenating a single Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook with the initial SPS HARQ-ACK information bits in a predefined order.

[0218] For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook provided in this application embodiment is formed by concatenating a single Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook with delayed SPS HARQ-ACK information bits in a predefined order.

[0219] For example, the Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook provided in this application embodiment is formed by concatenating a single Type 1 codebook, Type 2 codebook, or enhanced Type 2 codebook, initial SPS HARQ-ACK information, and delayed SPS HARQ-ACK information bits in a predefined order.

[0220] In at least one embodiment of this application, the method further includes:

[0221] The network-side device determines and reserves PUCCH resources for transmitting the second HARQ-ACK codebook according to a first method; the first method includes any one of the following:

[0222] Use the PUCCH resource corresponding to the second HARQ-ACK codebook; wherein, the priority corresponding to the second HARQ-ACK codebook remains unchanged;

[0223] Use the PUCCH resource corresponding to the first target priority.

[0224] Wherein, if the priority of the first target is different from the priority corresponding to the second HARQ-ACK codebook, the method further includes:

[0225] The network-side device determines and reserves the PUCCH resource corresponding to the first target priority based on the attributes of the second HARQ-ACK codebook.

[0226] Optionally, the first target priority mentioned above can be specified by the protocol or configured by higher-level parameters, for example, the first target priority can be set to high priority.

[0227] In at least one embodiment of this application, when the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, the network-side device can directly execute the second operation, or it can determine the specific content of the second operation before executing it. That is, before the network-side device executes the second operation, the method further includes:

[0228] The network-side device determines whether all the HARQ-ACK information corresponding to the first HARQ-ACK codebook is included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook;

[0229] When all the HARQ-ACK information corresponding to the first HARQ-ACK codebook is included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook, the network-side device determines the second operation as: abandoning the reception of the first HARQ-ACK codebook included in the second HARQ-ACK codebook, and receiving the second HARQ-ACK codebook;

[0230] If the HARQ-ACK information corresponding to the first HARQ-ACK codebook is not all included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook, the network-side device determines the second operation as: receiving the first HARQ-ACK codebook and the second HARQ-ACK codebook on a PUCCH resource.

[0231] It should be noted that "whether the HARQ-ACK information corresponding to the first HARQ-ACK codebook is all included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook" can be understood as: whether the HARQ process corresponding to the first HARQ-ACK codebook is all mapped to the HARQ process corresponding to the second HARQ-ACK codebook.

[0232] Optionally, when the first HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, and the second HARQ-ACK codebook is a Type 3 codebook or an enhanced Type 3 codebook, the network-side device determines whether all the HARQ-ACK information corresponding to the first HARQ-ACK codebook is included in the HARQ-ACK information corresponding to the second HARQ-ACK codebook, which can avoid inconsistencies between the terminal and the network-side device in their understanding of the codebook actually transmitted.

[0233] In summary, in the embodiments of this application, for first HARQ-ACK codebooks and second HARQ-ACK codebooks with different priorities, when the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, the network-side device only receives one HARQ-ACK codebook or receives the first HARQ-ACK codebook and the second HARQ-ACK codebook on one PUCCH resource, thereby avoiding redundant HARQ-ACK information transmission and improving HARQ-ACK transmission efficiency or transmission reliability. Alternatively, the network-side device ensures that the first HARQ-ACK codebook and the second HARQ-ACK codebook do not overlap, thereby reducing the implementation complexity of the terminal.
