Abstract

The present application discloses a method for generating a hybrid automatic repeat request response codebook. When the hybrid automatic repeat request response codebook format supports two DCI formats, a target is determined according to a first set threshold and a second set threshold. a timing difference set, including a first subset and a second subset, the first subset is a subset of the first timing difference set, and the second subset is a subset of the second timing difference set; according to the target timing The difference set determines the format of the HARQ-ACK codebook. The HARQ-ACK codebook bytes of the candidate PDSCH reception timing corresponding to the first subset element can be used to feed back the PDSCH scheduled by the first DCI format, and the candidate PDSCH reception timing corresponds to the second subset element. The HARQ‑ACK codebook bytes can be used to feed back the PDSCH scheduled in the second DCI format. The present application also includes apparatus for applying the method. The present application solves the problem that the network device cannot use the fallback DCI format and the non-fallback DCI format to schedule the PDSCH of the terminal device at the same time.

Description

technical field [0001] The present application relates to the field of wireless communication technologies, and in particular, to a method and device for generating a codebook for a hybrid automatic repeat request response. Background technique [0002] The HARQ mechanism is used in the NR system to improve the efficiency of data transmission. In the MAC layer, each cell has a HARQ entity, and the uplink and downlink are independent. Each HARQ entity contains multiple parallel HARQ processes. The ACK and NACK information are collectively referred to as hybrid automatic repeat request response information HARQ-ACK. The entirety of HARQ-ACK information fed back by a terminal equipment (UE) on one HARQ feedback resource (PUCCH or PUSCH) is called a HARQ-ACK codebook. [0003] There are three formats of the PDCCH for the existing scheduled PDSCH in the NR system: DCI format 1_0, DCI format 1_1 and DCI format 1_2. DCI format 1_0 is a fallback DCI format. The fallback DCI for...
