The present disclosure relates to the field of wireless communication technologies, and more particularly, to a method for determining a transmission parameter, a method for sending a HARQ-ACK, an apparatus, a device and a storage medium.
In order to ensure scheduling flexibility, one Downlink Control Information (DCI) can schedule one Physical Downlink Shared channel (PDSCH) or one Physical Uplink Shared channel (PUSCH).
When a Sub-Carrier Space (SCS) is 960 khz, a corresponding slot duration is 1/64 ms. In a case where the sub-carrier space is relatively large and the slot duration is relatively short, DCI blind detection overhead will be excessive if each PDSCH is scheduled with one separate DCI.
In a Multi Transmission Time Interval (multi-TTI) design, one DCI can schedule PDSCHs/PUSCHs in a plurality of slots.
An example in a multi-TTI PDSCH scheduling scenario is taken for illustration: one DCI can schedule four PDSCHs, and these four PDSCHs correspond to four consecutive slots in turn. The four PDSCHs can be used to transmit different data, that is, to transmit different Transport Blocks (TBs). By adopting the multi-TTI design, the number of DCIs can be reduced, thereby reducing complexity of the blind detection of the DCI by a UE.
In the multi-TTI PDSCH scheduling scenario, the number of PDSCHs scheduled by one DCI may be configured semi-statically by a higher layer, or may be, after a value range is indicated by a protocol or the value range is configured by a higher layer signaling, dynamically indicated by the scheduling DCI.
In the multi-TTI PDSCH scheduling scenario, it is necessary to feedback Hybrid Automatic Repeat reQuest Acknowledgements (HARQ-ACKs) for a plurality of PDSCHs on the same PUCCH.

A Type1 codebook is a HARQ-ACK feedback mode with a fixed HARQ-ACK codebook size. HARQ-ACKs for effective PDSCH candidate time-frequency resources in all slots contained in a fixed-size feedback window is fed back on a channel that feeds back a HARQ-ACK.
Configuration information about the Type1 HARQ-ACK codebook includes:
Configuration information 1: a first set (known as K1 set) is agreed by a protocol or configured through a higher layer signaling. This K1 set contains L integer elements, and each integer element indicates a slot interval between a PDSCH and a channel configured to feed back a HARQ-ACK for the PDSCH. The K1 set is {k1, k2, . . . , kL}.
A default K1 set specified by the protocol is {1, 2, 3, 4, 5, 6, 7, 8}. The K1 set configured by a base station contains at most 8 values from 0 to 15. Alternatively, in some protocols, the K1 set configured by the base station contains −1 and at most 8 values from 0 to 15.
Configuration information 2: a first interval value indicated in DCI is a value in the K1 set. The first interval value is denoted by ki.
Configuration information 3: a PDSCH scheduled by the DCI is in a slot N (a slot whose position identity is N).
According to the above-mentioned configuration information, a user equipment will send a HARQ-ACK for the PDSCH scheduled by the DCI on a channel in a slot N+ki.
A feedback window corresponding to the Type1 HARQ-ACK codebook that can be contained in the channel that feeds back the HARQ-ACK is a window composed of slots: {slot N+ki−k1, slot N+ki−k2, . . . slot N+ki−ki−1, slot N, slot N+ki−ki+1, . . . , slot N+ki−kL}
A manner to determine this window can be understood as performing forwards reverse deduction on slot N+ki of the channel by each integer value in the K1 set, and forming the feedback window from individual slots obtained through the reverse deduction. That is, the channel for the HARQ-ACK in the slot N+ki needs to contain HARQ-ACK information for each PDSCH in the feedback window.
A PDSCH candidate time-frequency resource in a certain slot in this feedback window is not scheduled, or there is an actual PDSCH scheduling, but the DCI indicates that the HARQ-ACK for the PDSCH is not fed back in the slot N+ki, a feedback result corresponding to the PDSCH candidate time-frequency resource in this slot is a Negative Acknowledgement (NACK).
When one DCI schedules multi-TTI PDSCHs, in the case of using the Type1 HARQ-ACK codebook, after the first interval value is indicated in the DCI, the Type1 HARQ-ACK codebook determined according to the first interval value cannot include HARQ-ACK information for all PDSCHs scheduled by the DCI.
For example:
The multi-TTI PDSCHs scheduled by one DCI include M PDSCHs in total, and slots corresponding to the M PDSCHs in turn are: slot n, slot n+1, . . . , slot n+M−1.
The configured K1 set contains L values, and the K1 set is {k1, k2, . . . , kL}.
The first interval value indicated in the DCI is a value in the K1 set. The first interval value is denoted by ki.
The user equipment will send the HARQ-ACK for the PDSCH scheduled by the DCI on a channel in slot n+M−1+ki.
The feedback window corresponding to the Type1 HARQ-ACK codebook that can be contained in the channel that feeds back the HARQ-ACK is a window composed of slots: {slot n+M−1+ki−k1, slot n+M−1+ki−k2, . . . , slot n+M−1+ki−ki−1, slot n+M−1, slot n+M−1+ki−ki+1, . . . , slot n+M−1+ki−kL}.
It is required that this window has to include the slot where each PDSCH among the multi-TTI PDSCHs is located, that is, each slot in {slot n, slot n+1, . . . , slot n+M−1}.
Whether the requirement can be realized is related to both the semi-statically configured K1 set and the first interval value dynamically indicated in the DCI. In the case of inappropriate configuration of the K1 set itself, no matter which value in the K1 set is indicated in the DCI, the above requirement cannot be met.
Based on the above information, it can be known that configuring the K1 set is a basic premise to meet the above requirement. Only when an appropriate K1 set is configured, the DCI can indicate an appropriate first interval value, so that the semi-static codebook on the channel that feeds back the HARQ-ACK can perform the HARQ-ACK feedback on all PDSCHs among the scheduled multi-TTI PDSCHs.
It should be noted that the channel configured to feed back the HARQ-ACK described in the present disclosure may be a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH), which is not limited here.
Embodiments of the present disclosure provide a method for determining a transmission parameter, which is applied to a network-side device. For example, the network-side device is a base station device.
