[0002] This disclosure relates to the field of wireless communication technology, and in particular to a HARQ-ACK codebook configuration and decoding method, apparatus, device and storage medium. Background Technology

[0003] Type 1 codebook is a fixed-size HARQ-ACK feedback method that uses a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook. On a HARQ-ACK physical uplink control channel (PUCCH), it is necessary to feed back HARQ-ACKs for all valid candidate physical downlink shared channels (PDSCH) on all time slots within a fixed-size feedback window.

[0004] In the NR 52.6-71GHz band, a scenario will be introduced where multiple PDSCH slots are scheduled via the Physical Downlink Control channel (PDCCH), i.e., a multi-slot PDSCH scheduling scenario. Due to the introduction of multi-slot PDSCH scheduling, determining the Type 1 codebook feedback window solely based on the K1 set in a single-slot scheduling scenario may result in the Type 1 codebook not completely encompassing all PDSCH slots scheduled by the Downlink Control Information (DCI).

Detailed Implementation

[0031] The embodiments of this disclosure will now be further described in conjunction with the accompanying drawings and specific implementation details.

[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0033] It should be noted that one embodiment of this disclosure may include multiple steps; for ease of description, these steps are numbered; however, these numbers are not a limitation on the execution time slots or execution order between the steps; these steps can be implemented in any order, and this disclosure does not limit this.

[0034] In a multi-slot PDSCH scheduling scenario, HARQ-ACKs for multiple PDSCHs scheduled by a single DCI are fed back within the same PUCCH. The PUCCH slot for HARQ-ACK feedback for these multiple PDSCHs is determined based on k1 in the scheduling DCI and the slot position of the last PDSCH. However, due to the introduction of multi-slot PDSCH scheduling, determining the Type1 codebook feedback window solely based on the K1 set in a single-slot scheduling scenario may result in the Type1 codebook not completely encompassing the slots containing all PDSCHs scheduled by the DCI.

[0035] This disclosure provides a HARQ-ACK codebook configuration method, which is executed by a user equipment. This method can be executed independently or in conjunction with any other embodiment of this disclosure. Figure 1 This is a flowchart illustrating a HARQ-ACK codebook configuration method according to an exemplary embodiment, such as... Figure 1 As shown, the method includes: Step 101: Based on the time series K1 set in the first scenario and the time series K0 set in the second scenario, determine the time series K1 set in the second scenario; Step 102: Configure the HARQ-ACK codebook based on the time series K1 set in the second scenario; Wherein, each time sequence k1 in the time sequence K1 set is the time interval between the time unit for transmitting the Physical Downlink Shared Channel (PDSCH) and the time unit for transmitting the Physical Uplink Control Channel (PUCCH), and each time sequence k0 in the time sequence K0 set is the time interval between the time unit for transmitting the PDSCH and the time unit for transmitting the Physical Downlink Control Channel (PDCCH). The first scenario is a scenario where a single PDSCH time slot is scheduled via PDCCH, and the second scenario is a scenario where multiple PDSCH time slots are scheduled via PDCCH.

[0036] In one embodiment, the user equipment obtains the timing K1 set for a single PDSCH time slot scheduled via PDCCH and the timing K0 set for multiple PDSCH time slots scheduled via PDCCH. Based on the obtained timing K1 and timing K0 sets, it determines the timing K1 set for multiple PDSCH time slots scheduled via PDCCH. Then, it configures the HARQ-ACK codebook based on the timing K1 set for multiple PDSCH time slots scheduled via PDCCH.

[0037] In one implementation, the user equipment receives a time series K1 set configured by the network device for a first scenario from the network device, or obtains the time series K1 set for the first scenario based on a communication protocol. In one implementation, the user equipment receives a time series K0 set configured by the network device for a second scenario from the network device. In one implementation, the user equipment receives a Time Domain Resource Allocation (TDRA) table from the network device and obtains the time series K0 set for the second scenario based on the TDRA table.

[0038] In the above implementation, the timing K1 set in the second scenario is determined based on the timing K1 set in the first scenario and the timing K0 set in the second scenario, so that the feedback window of the codebook based on the timing K1 set in the second scenario can include all PDSCHs scheduled by a DCI, so that the HARQ-ACK of PDSCHs with multiple transmission time intervals can be fed back in a HARQ-ACK codebook.

[0039] This disclosure provides a HARQ-ACK codebook configuration method, which is executed by a user equipment. This method can be executed independently or in conjunction with any other embodiment of this disclosure. Specifically, the timing K0 set in the second scenario includes at least one timing K0 group, each timing K0 group includes multiple timing k0s, and each timing K0 group corresponds to a time-domain resource scheduling mode in the second scenario.

[0040] In one implementation, the time series K0 set in the second scenario includes multiple time series K0 groups, each time series K0 group includes multiple time series k0, and each time series K0 group corresponds to a time domain resource scheduling method in the second scenario.

[0041] In one implementation, the time-series K0 set for the second scenario is obtained based on the Time Domain Resource Allocation (TDRA) table configured for network devices. The TDRA table is shown in Table 1. Table 1 TDRA Table

[0042] DMRS stands for Demodulation Reference Signal.

[0043] In this TDRA table, each row corresponds to a time-domain resource scheduling method. The time-domain resource scheduling methods identified by row indices 2 and 3 each correspond to multiple time series k0s. Therefore, row indices 2 and 3 correspond to time series K0 groups (0,1,1,2) and (1,2,3,4,5,6,7,8), respectively. At this time, the time series K0 set in the second scenario includes time series K0 groups (0,1,1,2) and (1,2,3,4,5,6,7,8).

[0044] It is understood that each element in Table 1 exists independently. These elements are listed in the same table as an example, but this does not mean that all elements in the table must exist simultaneously as shown in the table. The value of each element is independent of the values ​​of any other element in Table 1. Therefore, those skilled in the art will understand that the value of each element in Table 1 is an independent embodiment.

[0045] In the above implementation, the timing K0 set in the second scenario is combined to determine the timing K1 set in the second scenario, so that the feedback window of the codebook based on the timing K1 set in the second scenario can include all PDSCHs scheduled by a DCI, so that the HARQ-ACK of PDSCHs with multiple transmission time intervals can be fed back in a HARQ-ACK codebook.

[0046] In the above implementation, the timing K0 set in the second scenario is combined to determine the timing K1 set in the second scenario, so that the feedback window of the codebook based on the timing K1 set in the second scenario can include all PDSCHs scheduled by a DCI, so that the HARQ-ACK of PDSCHs with multiple transmission time intervals can be fed back in a HARQ-ACK codebook.

[0047] This disclosure provides a HARQ-ACK codebook configuration method, which is executed by a user equipment.

The first scenario is a scenario where a single PDSCH time slot is scheduled via PDCCH, and the second scenario is a scenario where multiple PDSCH time slots are scheduled via PDCCH.

Furthermore, based on the timing K1 set for the first scenario and the timing K0 set for the second scenario, a timing K1 set for the second scenario is determined. Then, a HARQ-ACK codebook is configured based on the timing K1 set for the second scenario. In one implementation, the second configuration information is Radio Resource Control (RRC) signaling.

[0053] In one implementation, the user equipment (UE) obtains a timing K1 set for a first scenario based on a communication protocol. The UE receives second configuration information from a network device and obtains a timing K0 set for a second scenario based on this second configuration information. Furthermore, based on the timing K1 set for the first scenario and the timing K0 set for the second scenario, the UE determines the timing K1 set for the second scenario. Then, a HARQ-ACK codebook is configured based on the timing K1 set for the second scenario.

Furthermore, based on the timing K1 set for the first scenario and the timing K0 set for the second scenario, a timing K1 set for the second scenario is determined.
