Method of performing hybrid automatic repeat request codebook generation and related device

A method for a base station (BS) for performing a hybrid automatic repeat request (HARQ) codebook generation operation for downlink transmissions, the method comprising:

• transmitting, to a user equipment (UE), a dynamic scheduling configuration for a HARQ feedback operation;
• transmitting, to the UE, scheduling signaling for a physical downlink shared channel (PDSCH) transmission to disable a HARQ state feedback for the PDSCH transmission;
• and
• receiving, from the UE, a HARQ codebook, wherein
• the HARQ codebook excludes a HARQ state for the PDSCH transmission and is generated without counting a physical downlink control channel (PDCCH) transmission in a downlink assignment index (DAI) value indicated in the scheduling signaling.

A user equipment (UE) for performing a hybrid automatic repeat request (HARQ) codebook generation operation for downlink receptions, the UE comprising:

• at least one processor;
• and
• at least one non-transitory computer-readable medium coupled to the at least one processor and storing one or more computer-executable instructions that, when executed by the at least one processor, cause the UE to:
• receive, from a base station, a dynamic scheduling configuration for a HARQ feedback operation;
• receive, from the base station, scheduling signaling for a first physical downlink shared channel (PDSCH) reception to disable a first HARQ state feedback for the first PDSCH reception;
• and
• generate, for the HARQ feedback operation, a HARQ codebook that excludes a first HARQ state for the first PDSCH reception, wherein the HARQ codebook is generated without counting a first physical downlink control channel (PDCCH) reception in a downlink assignment index (DAI) value indicated in the scheduling signaling.
