HARQ-ACK TRANSMISSION METHOD AND DEVICE FOR MULTI-PDSCH SCHEDULING AND PDSCH REPETITION IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2023/132558

A1

The present disclosure relates to a 5G or 6G communication system for supporting higher data transfer rates. The present disclosure provides a method of, when a terminal receives PDSCH repetitive transmission and scheduling of multiple PDSCHs through one DCI in a wireless communication system, collecting pieces of HARQ-ACK information of the PDSCHs to generate a type-1 HARQ-ACK codebook.
