To facilitate a better understanding of the embodiments of the present application, the related technologies of the present application are described first.

In the NR system, a semi-static HARQ-ACK codebook can be supported, such as a Type 1 (Type-1) Hybrid Automatic Repeat request Acknowledgment (HARQ-ACK) codebook or Type 3 (Type-3) HARQ-ACK codebook, and dynamic feedback codebook (dynamic HARQ-ACK codebook), such as type 2 (Type-2) or enhanced type 2 (eType-2) HARQ-ACK codebook feedback .

For the Type-1 HARQ-ACK codebook, it can be based on the number of configured serving cells, the feedback timing (timing) set from the Physical Downlink Shared Channel (PDSCH) to HARQ-ACK (that is, the set of K ₁ ) and the timing Domain resource allocation indicates a series of row indexes (a set of row indexes R) in the domain (Time Domain Resource Allocation, TDRA) table, each row defines the slot offset (slot offset) K0 from PDCCH to PDSCH, the start symbol and length Indicates (start and length indicators, SLIV), and PDSCH mapping type (mapping type), using a semi-static method to determine the candidate PDSCH reception opportunities (occasions for candidate PDSCH receptions), and then determine the number of bits of the corresponding ACK/NACK feedback information , that is, the number of ACK/NACK bits included in the HARQ-ACK codebook does not depend on the number of actually received PDSCHs, but is determined according to the receiving opportunities of semi-statically configured candidate PDSCHs (ie, the maximum number of receivable PDSCHs). Using the Type-1 HARQ-ACK codebook can avoid the ambiguity between the terminal device and the network device on the size of the HARQ-ACK codebook caused by the fact that the terminal device has not received part of the PDSCH, resulting in the network device being unable to correctly receive the feedback information sent by the terminal device The problem.

Since the terminal device can only receive at most one PDSCH at the same time in one carrier, as shown in FIG. 2 , the terminal device cannot receive PDSCH on PDSCH candidate receiver opportunity 1, PDSCH candidate receiver opportunity 2 and PDSCH candidate receiver opportunity 3 at the same time. If the corresponding bits of HARQ-ACK feedback information are reserved for candidate PDSCH receiver opportunity 1, PDSCH candidate receiver opportunity 2, and PDSCH candidate receiver opportunity 3 in the Type-1 HARQ-ACK codebook, there must be HARQ-ACK feedback Information redundancy, therefore, the three PDSCH candidate receivers can share one feedback information bit in the codebook. That is, when the terminal device receives a PDSCH in any one of the three candidate PDSCH receiving opportunities, its corresponding ACK/NACK information is mapped to the same feedback information bit. Similarly, the PDSCH candidate receiver opportunity 4 and the PDSCH subsequent receiver opportunity 5 may also share one feedback information bit. Based on this method, for the example shown in Figure 2, the candidate PDSCH receivers in this time slot need to correspond to 2 feedback information bits in the Type-1 HARQ-ACK codebook (taking single codeword transmission as an example, that is, A PDSCH carries only one transport block (Transport Block, TB), corresponding to one bit of feedback information). In addition, if the terminal device does not have the ability to receive multiple unicast PDSCHs in one time slot, the five candidate PDSCH receivers in Figure 2 share one feedback information bit, that is, the five candidate PDSCH receivers Any one of them receives the PDSCH, and its corresponding ACK/NACK information is mapped to the same feedback information bit.

In some scenarios, in order to reduce PDCCH overhead, Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS) is introduced. Based on the SPS configuration (SPS configuration), the network device sends the activation downlink control information (Downlink Control Information, DCI) once to schedule multiple downlink transmissions that occur periodically. The downlink transmission scheduled by the SPS configuration may be called SPS PDSCH.

For example, SPS configuration is configured per serving cell (perserving cell), or configured per bandwidth part (Band Width Part, BWP), for example, through radio resource control (Radio Resource Control, RRC) signaling configuration, SPS configuration includes periodic information , HARQ process, etc., and then activate/deactivate the DCI scrambled by the pre-configured scheduling radio network temporary identifier (Configured Scheduling RNTI, CS-RNTI), and activate/deactivate the time-frequency resources occupied by the SPS PDSCH in the activation/deactivation DCI , Modulation and Coding Scheme (MCS) used, PDSCH to HARQ-ACK feedback timing and other information to indicate.

In some scenarios, for SPS deactivation DCI (SPS release), the terminal device needs to feed back 1-bit HARQ-ACK information.

In some scenarios, one or more SPS configurations (SPS configurations) can be activated on a BWP at the same time, and the SPS cycle supports at least 1 slot. For multiple SPS configurations, three methods are supported: separate activation, separate deactivation, and joint deactivation. Separate activation/deactivation means that one DCI only activates/deactivates one SPS configuration, and joint deactivation means that one DCI can deactivate multiple SPS configurations at the same time. SPS configuration. For the DCI (separate release DCI) that is deactivated separately and the DCI (joint release DCI) that is jointly deactivated, the terminal device needs to feed back 1-bit HARQ-ACK information. For separate release DCI, the position of its HARQ-ACK information in the Type-1 HARQ-ACK codebook is the same as the position of the HARQ-ACK information received by the SPS PDSCH corresponding to the DCI. For joint release DCI, its HARQ-ACK information is in Type-1 The position of the HARQ-ACK codebook is the same as the position of the HARQ-ACK information received by the SPS PDSCH corresponding to the SPS configuration with the smallest configuration index in the DCI deactivated SPS configuration.

To sum up, the terminal device needs to feed back 1-bit HARQ-ACK information to SPS release DCI and 1-bit HARQ-ACK information to SPS PDSCH, but when there is at least one SPS configuration corresponding to SPS PDSCH overlapping in time domain, and in How to create a HARQ-ACK codebook for a terminal device when receiving DCI in this time slot is an urgent problem to be solved.

For example, as shown in Figure 3, the terminal device receives SPS release DCI for release (SPS configuration 2) in a time slot, and SPS PDSCH 1 (corresponding to SPS configuration 1), SPS PDSCH 2 is configured in this time slot (corresponding to SPS configuration 2), where the SPS release DCI, SPS PDSCH 1 and SPS PDSCH 2 share feedback information bits in the Type-1 HARQ-ACK codebook. In this case, how does the terminal device generate the corresponding HARQ-ACK Information is a burning problem.

Embodiment 1-3: The terminal device generates target HARQ-ACK information according to the first DCI and the target PDSCH.

In some embodiments, the terminal device may report combined HARQ-ACK information of the first DCI and the target PDSCH.

It should be understood that, for the manner of determining the target PDSCH, refer to the related description of Embodiment 1-2, and for the sake of brevity, details are not repeated here.

For example, the terminal device may determine the target HARQ-ACK information according to the HARQ-ACK information corresponding to the first DCI and the HARQ-ACK information corresponding to the target PDSCH. Or, generate the target HARQ-ACK information according to the detection result of the first DCI and the demodulation result of the target PDSCH.

In some embodiments, the target HARQ-ACK information is a binary AND result of the HARQ-ACK information corresponding to the first DCI and the HARQ-ACK information corresponding to the target PDSCH.

For example, if the terminal device detects the first DCI and correctly demodulates the target PDSCH, it generates ACK information, otherwise it generates NACK.

In some other embodiments, the target HARQ-ACK information is a binary OR result of the HARQ-ACK information corresponding to the first DCI and the HARQ-ACK information corresponding to the target PDSCH.

For example, if the terminal device detects the first DCI or correctly demodulates the target PDSCH, it generates ACK information, otherwise it generates NACK.

It should be understood that, in some embodiments, when multiple SPS PDSCHs correspond to the same feedback information bit in the HARQ-ACK codebook, the terminal device preferentially selects to receive the SPS PDSCH corresponding to the SPS configuration with the smallest SPS configuration index, and further generates the SPS PDSCH The HARQ-ACK information corresponding to the SPS PDSCH does not receive other SPS PDSCHs, and does not generate the corresponding HARQ-ACK information of other SPS PDSCHs.

In some embodiments, when the DCI and the SPS PDSCH corresponding to the SPS configuration released by the DCI correspond to the same feedback information bit in the HARQ-ACK codebook, the terminal device can only receive the DCI and generate the corresponding HARQ-ACK codebook. ACK information, does not receive the corresponding SPS PDSCH, and does not generate the HARQ-ACK information corresponding to the SPS PDSCH.

In conjunction with the example in Figure 3, the network device configures SPS PDSCH 1 and SPS PDSCH 2 in one time slot, wherein the SPS PDSCH 1 and SPS PDSCH 2 correspond to SPS configuration 1 and SPS configuration 2 respectively, and the network device is in The release DCI used to release SPS configuration 2 is sent at the beginning of the time slot, and the HARQ-ACK information of the SPS PDSCH 1, SPS PDSCH 2 and SPS release DCI used to release SPS configuration 2 corresponds to the same PUCCH, and the HARQ configured by the network device - The ACK codebook type is Type-1 HARQ-ACK codebook.

In this case, for the associated SPS release DCI and the SPS PDSCH corresponding to the released SPS configuration, the terminal device receives the SPS release DCI first, does not receive the corresponding SPS PDSCH, and does not generate HARQ-ACK information for the SPS PDSCH.

In this example, the SPS release DCI is used to release the SPS configuration 2, then the terminal device does not receive the SPS PDSCH 2 corresponding to the SPS configuration 2, and does not generate the HARQ-ACK information of the SPS PDSCH 2.

For the associated SPS release DCI and the SPS PDSCH corresponding to the released SPS configuration, the terminal device receives the SPS release DCI first, does not receive the corresponding SPS PDSCH, and does not generate HARQ-ACK information for the SPS PDSCH.

For SPS release DCI and SPS PDSCH that do not have an association relationship, the target HARQ-ACK information can be generated in the following manner:

Corresponding to Embodiment 1-1: the terminal device receives the SPS release DCI, and generates the HARQ-ACK information corresponding to the SPS release DCI on the corresponding feedback information bits in the Type-1 HARQ-ACK codebook.

Optionally, the terminal device does not receive the SPS PDSCH corresponding to the SPS configuration that has not been released by the SPS release DCI instruction, that is, SPS PDSCH 1, and/or, the terminal device does not generate HARQ-ACK information for the SPS PDSCH 1, that is, does not report the SPS PDSCH 1 HARQ-ACK information.

Corresponding to Embodiment 1-2: the terminal device receives the SPS PDSCH corresponding to the SPS configuration that has not been released by the SPS release DCI instruction, that is, SPS PDSCH 1, and/or, the terminal device generates HARQ-ACK information for the SPS PDSCH 1, that is, reports the SPS HARQ-ACK information of PDSCH 1. That is, the terminal device generates the HARQ-ACK information corresponding to the SPS PDSCH 1 on the corresponding feedback information bit in the Type-1 HARQ-ACK codebook.

Optionally, the terminal device does not generate HARQ-ACK information for the SPS release DCI, that is, does not report the HARQ-ACK information of the SPS release DCI.

Corresponding to Embodiment 1-3: the terminal device reports the combined HARQ-ACK information of the SPS PDSCH corresponding to the SPS release DCI and the SPS configuration not indicated by the SPS release DCI to be released.

In this embodiment, the terminal device receives the SPS PDSCH corresponding to the SPS configuration not released by the SPS release DCI instruction, that is, SPS PDSCH 1.

In this embodiment, the terminal device generates the HARQ-ACK information of the SPS release DCI, which is recorded as the first HARQ-ACK information, and generates the HARQ-ACK information of the SPS PDSCH 1, which is recorded as the second HARQ-ACK information. Further process the first HARQ-ACK information and the second HARQ-ACK information to obtain the target HARQ-ACK information, and generate the target HARQ-ACK information into the corresponding feedback information bits in the Type-1 HARQ-ACK codebook superior.

For example, the target HARQ-ACK information is a binary AND result of the first HARQ-ACK information and the second HARQ-ACK information.

For another example, the target HARQ-ACK information is a binary OR result of the first HARQ-ACK information and the second HARQ-ACK information.

Embodiment 2: The terminal device reports the HARQ information corresponding to the first DCI and the target PDSCH.

That is, the target HARQ-ACK information includes the HARQ-ACK information corresponding to the first DCI and the HARQ-ACK information corresponding to the target PDSCH.

It should be understood that, for the manner of determining the target PDSCH, refer to the related description of Embodiment 1, and for the sake of brevity, details are not repeated here.

In this case, 2 bits are required in the HARQ-ACK codebook to bear the HARQ-ACK information corresponding to the first DCI and the HARQ-ACK information corresponding to the target PDSCH respectively.

In this embodiment 2, the position of the HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook is not based on the position of the HARQ-ACK information corresponding to the SPS PDSCH associated with the first DCI in the HARQ-ACK codebook. The position in the ACK codebook is determined, but a new determination method is adopted to make the position of the HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook and the HARQ-ACK information corresponding to the target PDSCH The positions in the HARQ-ACK codebook are different.

As an example, the position of the HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook is determined according to the TDRA field in the first DCI, or may be determined according to other information fields in the first DCI, No particular limitation is made here. For example, the network device may set the value of the TDRA field so that the position of the HARQ-ACK information determined by the terminal device according to the TDRA field in the first DCI in the HARQ-ACK codebook is different from that according to the associated The position determined by the SPS PDSCH in the HARQ-ACK codebook.

In some embodiments, the position of the HARQ-ACK information corresponding to the target PDSCH in the HARQ-ACK codebook is based on the time domain resource (such as the start symbol and symbol length) occupied by the target PDSCH, or, the corresponding Candidate PDSCH receivers are determined.

In this embodiment, for SPS release DCI and SPS PDSCH that have no association relationship, the terminal device may report HARQ-ACK information corresponding to SPS release DCI and SPS PDSCH 1 respectively.

In this embodiment, the position of the HARQ-ACK information corresponding to the SPS release DCI in the Type-1 HARQ-ACK codebook is determined according to the TDRA field in the SPS release DCI.

For example, if the TDRA field indicates the candidate PDSCH receiving opportunity 1 in Figure 2, and the symbol occupied by the SPS PDSCH 1 associated with the SPS release DCI corresponds to the candidate PDSCH receiving opportunity 4, then the HARQ-ACK information corresponding to the SPS release DCI is in The position in the Type-1 HARQ-ACK codebook is the index corresponding to candidate PDSCH receiver opportunity 1, and the position of the HARQ-ACK information corresponding to SPS PDSCH 1 in the Type-1 HARQ-ACK codebook is the index corresponding to candidate PDSCH receiver opportunity 4 index. Therefore, by setting the value of the TDRA field, the SPS release DCI and SPS PDSCH 1 correspond to different positions in the Type-1 HARQ-ACK codebook, so that the SPS release DCI can be reported through the same Type-1 HARQ-ACK codebook HARQ-ACK information corresponding to SPS PDSCH 1 respectively.

To sum up, when there is at least one SPS PDSCH of SPS configuration in a time unit, and SPS release DCI is received in this slot, and the SPS release DCI indicates that the SPS configuration with the smallest SPS configuration index released is included in the at least In an SPS configuration, and at least one HARQ-ACK information of SPS PDSCH and SPS release DCI corresponds to the same feedback information bit in the Type-1 HARQ-ACK codebook, the terminal device can construct Type-1 HARQ in the following manner -ACK codebook:

Mode 1 (corresponding to Embodiment 1): The terminal device only reports the HARQ-ACK information of the SPS release DCI, or only reports the HARQ-ACK information of the SPS PDSCH corresponding to the SPS configuration not released by the SPS release DCI instruction, or reports both The combination of HARQ-ACK information based on this method does not change the construction rules of the Type-1 HARQ-ACK codebook, and can be better compatible with the existing technology.

Mode 2 (corresponding to Embodiment 2): The terminal device reports the HARQ-ACK information corresponding to the SPS release DCI and the HARQ-ACK information corresponding to the SPS PDSCH. In this mode, the network device can learn the HARQ-ACK information corresponding to the SPS release and the SPS PDSCH The corresponding HARQ-ACK information can assist the subsequent scheduling of network devices and improve the reliability of data transmission.

As an alternative implementation manner, the terminal device does not expect the HARQ-ACK information corresponding to the at least one PDSCH and the HARQ-ACK information corresponding to the first DCI to be multiplexed and transmitted on the same uplink channel; and/or,

The terminal device does not expect the first DCI to be the same as the first information corresponding to the at least one PDSCH, or the terminal device does not expect the HARQ-ACK information corresponding to the first DCI to correspond to the at least one PDSCH The positions of the HARQ-ACK information in the HARQ-ACK codebook are the same, wherein the first information is the index of the candidate PDSCH receiving opportunity or the index of the SPS PDSCH release.

That is to say, the terminal device does not expect that the SPS release DCI sent by the network device in a time unit is configured to be fed back through the same HARQ-ACK codebook as the SPS PDSCH configured in the time unit, and/or, does not expect the network The SPS release DCI sent by the device in a time unit is configured to correspond to the same feedback information bit as the SPS PDSCH configured in the time unit in the HARQ-ACK codebook.

Furthermore, the terminal device does not expect that the SPS release DCI sent by the network device in a time unit is configured or indicated as being configured on the time unit and the SPS PDSCH not associated with the DCI through the same HARQ-ACK codebook Feedback, and/or the SPS release DCI that is not expected to be sent by the network device on a time unit is configured to correspond to the same feedback information bit in the HARQ-ACK codebook as the SPS PDSCH configured on the time unit that is not associated with the DCI bit.

By designing the network device to send the first DCI on the first time unit and the SPS PDSCH configured on the first time unit does not have the above-mentioned multiplexing relationship, so that the terminal device can construct the HARQ-ACK codebook according to the existing rules, correspondingly, The network device can also analyze the HARQ-ACK codebook according to the existing rules, so as to ensure that the terminal device and the network device have the same understanding of the HARQ-ACK information carried by the HARQ-ACK codebook.

In some embodiments, the terminal device is configured with at least one PDSCH in the first time unit, and the at least one PDSCH is not dynamically scheduled. In other words, the at least one PDSCH is not scheduled through a physical downlink control channel (Physical Downlink Control Channel, PDCCH).

In some embodiments, the at least one PDSCH corresponds to at least one SPS configuration (SPS configuration). Wherein, there is a one-to-one correspondence between the at least one PDSCH and the at least one SPS configuration. That is, the at least one PDSCH may be at least one SPS PDSCH.

In some embodiments, the HARQ-ACK information of the at least one PDSCH will be multiplexed and transmitted on the same uplink channel, that is, the HARQ-ACK information of the at least one PDSCH needs to be carried in the same HARQ-ACK codebook for transmission. As an example but not a limitation, the uplink channel may be a physical uplink control channel (Physical Uplink Control Channel, PUCCH).

In some embodiments, the SPS configuration corresponding to the at least one SPS PDSCH configured in the first time unit does not include the SPS configuration that the second DCI indicates release.

In some embodiments, the HARQ-ACK information corresponding to the at least one PDSCH and the HARQ-ACK information corresponding to the second DCI are not multiplexed and transmitted on the same physical uplink control channel PUCCH. That is, the HARQ-ACK information corresponding to the second DCI and the HARQ-ACK information corresponding to the at least one PDSCH are not transmitted through the same HARQ-ACK codebook.

In some embodiments, the second DCI is different from the first information corresponding to the at least one PDSCH, or, the HARQ-ACK information corresponding to the second DCI is different from the HARQ-ACK information corresponding to the at least one PDSCH The positions in the HARQ-ACK codebook are different. That is, the HARQ-ACK information corresponding to the second DCI and the HARQ-ACK information corresponding to the at least one PDSCH correspond to different feedback information bits in the HARQ-ACK codebook.

Optionally, the first information is an index of the candidate PDSCH receiving opportunity, or the first information is an index of an SPS PDSCH release (release). That is to say, the index of the candidate PDSCH receiving opportunity corresponding to the second DCI and the at least one PDSCH is different, or the index of the SPS PDSCH release corresponding to the second DCI and the at least one PDSCH is different. Or, the second DCI and the at least one PDSCH correspond to different candidate PDSCH receiving opportunities, or, the second DCI and the at least one PDSCH correspond to different SPS PDSCH releases.

In some embodiments, since the second DCI and at least one PDSCH correspond to different HARQ-ACK codebooks, or correspond to different feedback information bits in the HARQ-ACK codebook, that is, the second DCI and the at least one PDSCH A PDSCH does not have the problem of sharing feedback information bits. In this case, a HARQ-ACK codebook can be created according to existing rules. For specific implementation, refer to related technologies, and details will not be repeated here.

In some embodiments of the present application, the method 300 further includes:

Wherein, the HARQ-ACK information corresponding to the at least one PDSCH and the HARQ-ACK information corresponding to the first DCI are multiplexed and transmitted on the same PUCCH; and/or,

The first DCI is the same as the first information corresponding to the at least one PDSCH, or the HARQ-ACK information corresponding to the first DCI and the HARQ-ACK information corresponding to the at least one PDSCH are in the HARQ-ACK codebook in the same position.

It should be understood that for the specific implementation of the first DCI, refer to the related description of the first DCI in the method 200, and details are not repeated here for the sake of brevity.

That is to say, the terminal device does not expect the network device to send such SPS release DCI in a time unit, wherein the SPS release DCI and the SPS PDSCH configured in the time unit are fed back through the same HARQ-ACK codebook, and/ Or, the SPS release DCI and the SPS PDSCH configured on the time unit correspond to the same feedback information bits in the HARQ-ACK codebook.

By designing the network device not to send the first DCI that satisfies the above conditions in the first time unit, the terminal device can construct the HARQ-ACK codebook according to the existing rules, and correspondingly, the network device can also use the existing rules for the HARQ-ACK The codebook is analyzed to ensure that the terminal device and the network device have a consistent understanding of the HARQ-ACK information carried by the HARQ-ACK codebook.

In some embodiments, the terminal device is configured with at least one SPS PDSCH in the first time unit, then when the SPS release DCI is sent on the first time unit, the SPS release DCI and at least one SPS PDSCH need to meet the above constraints, When the SPS release DCI is sent in other time units such as the second time unit, the SPS release DCI may not need to satisfy the above constraints.

In conjunction with the example in Figure 7, the network device configures the candidate PDSCH receiving opportunities of SPS PDSCH 1 and SPS PDSCH 2 in time slot n, and does not configure the candidate PDSCH receiving opportunities of SPS PDSCH 1 in time slot n+1. Wherein, the SPS PDSCH 1 and SPS PDSCH 2 correspond to SPS configuration 1 and SPS configuration 2 respectively. Then, for the release DCI used to release SPS configuration 2, the terminal device does not expect to receive the SPS release DCI in time slot n, and the terminal device expects to receive the SPS release DCI in time slot n+1. In this time slot n+1, the terminal device does not receive SPS PDSCH 2, does not generate HARQ-ACK information of SPS PDSCH 2, and the terminal device generates HARQ-ACK information of SPS release DCI.

In summary, by designing the network device not to send the first DCI of the HARQ-ACK information shared with the HARQ-ACK of at least one SPS PDSCH configured on the first time unit, the terminal device can be constructed according to the existing rules HARQ-ACK codebook, correspondingly, the network device can also analyze the HARQ-ACK codebook according to the existing rules, so as to ensure that the terminal device and the network device have the same understanding of the HARQ-ACK information carried by the HARQ-ACK codebook .
