Document Type and Number:
WIPO Patent Application WO/2022/030813
Kind Code:
A1
Abstract:
The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. According to various embodiments of the present disclosure, a method performed by a transmission apparatus in a wireless communication system may be provided. The method may comprise the steps of: transmitting, via a physical downlink control channel (PDCCH), first control information for scheduling a group common-physical downlink shared channel (GC-PDSCH) via which multicast data is transmitted, including information related to hybrid automatic repeat request (HARQ) feedback for the multicast data; and transmitting, via the PDCCH, second control information for scheduling a physical downlink shared channel (PDSCH) via which unicast data is transmitted, including information related to HARQ feedback for the unicast data.
