Abstract
Provided are a codebook determination method, a codebook determination apparatus, a terminal, a base station and a storage medium. The codebook determination method includes that a UE determines, based on a timing of being awakened, a timing at which physical downlink shared channel (PDSCH) data is receivable by the UE; and the UE forms a corresponding Hybrid Automatic Repeat reQuest-acknowledgement (HARQ-ACK) codebook based on the timing at which the PDSCH data is receivable.
Claims23
A codebook determination method, comprising:
- determining, by a user equipment (UE) based on a timing of being awakened, a timing at which physical downlink shared channel (PDSCH) data is receivable by the UE;
- and
- forming, by the UE, a corresponding Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK) codebook based on the timing at which the PDSCH data is receivable.

A codebook determination method, comprising:
- receiving, by a user equipment (UE), signaling, wherein one or more k1 value sets or one or more k0 value sets are configured in the signaling;
- receiving, by the UE, an indication of a base station and selecting, by the UE, one k1 or k0 value set from the k1 value sets or the k0 value sets according to the indication;
- or selecting, by the UE, one k1 or k0 value set from the k1 value sets or the k0 value sets according to a rule agreed between the UE and the base station;
- and
- generating, by the UE, a Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK) codebook based on the selected k1 or k0 value set,
- wherein the interval k1 satisfies that in response to an end of a physical downlink shared channel (PDSCH) received by the UE being in slot n, an HARQ-ACK corresponding to the PDSCH is transmitted in slot n+k1;
- the interval k0 satisfies that in response to an end of downlink control information (DCI) which is used for scheduling PDSCH and received by the UE being in slot n, the PDSCH corresponding to the DCI is transmitted in slot n+k0;
- and
- wherein the rule agreed between the UE and the base station comprises one of the following:
- a DCI format, a type of traffic scheduled through the DCI, or a type of a Radio Network Tempory Identity (RNTI) used by the DCI.
14-20. (canceled)
A codebook determination method, comprising:
- configuring, by a base station, one or more k1 value sets or one or more k0 value sets for a user equipment (UE);
- instructing, by the base station, the UE to select one k1 or k0 value set from the k1 value sets or the k0 value sets;
- or determining, by the base station, that the UE selects one k1 or k0 value set from the k1 value sets or the k0 value sets according to a rule agreed between the UE and the base station;
- and
- determining, by the base station, that the UE formsgenerates a Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK) codebook based on the selected k1 or k0 value set,
- wherein the interval k1 satisfies that in response to an end of a physical downlink shared channel (PDSCH) received by the UE being in slot n, an HARQ-ACK corresponding to the PDSCH is transmitted in slot n+k1;
- the interval k0 satisfies that in response to an end of downlink control information (DCI) which is used for scheduling PDSCH and received by the UE being in slot n, the PDSCH corresponding to the DCI is transmitted in slot n+k0;
- and
- wherein the rule agreed between the UE and the base station comprises one of the following:
- a DCI format, a type of traffic scheduled through the DCI, or a type of a Radio Network Tempory Identity (RNTI) used by the DCI.
