METHOD AND APPARATUS FOR APPLYING HARQ TO MULTICAST BROADCAST SERVICE IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2021/194204

Kind Code:

A1

Abstract:

A method of a terminal in a wireless communication system, according to an embodiment of the present disclosure, may comprise the steps of: receiving, from a base station, multicast broadcast service (MBS) configuration information including information about at least one hybrid automatic repeat request (HARQ) process for an MBS; receiving MBS data from the base station on the basis of the MBS configuration information; and processing the MBS data on the basis of an HARQ process corresponding to the MBS data among the at least one HARQ process for the MBS.
