METHOD AND APPARATUS FOR DETERMINING SEMI-STATIC FEEDBACK CODEBOOK, AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2022/028410

Kind Code:

A1

Abstract:

Provided are a method and apparatus for determining a semi-static feedback codebook, and a storage medium. The method comprises: when a physical downlink shared channel (PDSCH), which is scheduled by means of a reference start and length indicator value (SLIV), is configured in a carrier, and repeated transmission of the PDSCH is not configured, and/or semi-static scheduling (SPS) transmission is not configured, extending an SLIV set in a pre-set time domain resource allocation (TDRA) table in a target time slot; and determining a semi-static feedback codebook on the basis of the extended SLIV set of each target time slot, wherein the target time slot is a time slot with a physical downlink control channel (PDCCH) monitoring occasion of downlink control information (DCI) in a pre-set format. By means of the embodiments of the present application, redundant feedback bits are removed, the size of a semi-static feedback codebook is reduced, and the feedback performance is improved.
