US 2025/0062929 A1 · GROUPCAST TRANSMISSION METHOD AND APPARATUS THEREFOR

Abstract

A method for performing sidelink groupcast transmission by a transmission terminal includes the steps of: classifying reception terminals belonging to a subject group into two or more subgroups; allocating different groupcast feedback schemes to the two or more subgroups; performing groupcast transmission to the reception terminals; and receiving feedback information from terminals belonging to at least one subgroup among the two or more subgroups according to the different groupcast feedback schemes.

Dependent claims

A method for sidelink groupcast transmission, performed in a transmitting terminal, the method comprising:

configuring a groupcast feedback scheme;
transmitting sidelink control information (SCI) indicating resource allocation information and the groupcast feedback scheme to at least one receiving terminal;
performing groupcast transmission based on the resource allocation information;
and
receiving feedback information from one or more of the at least one receiving terminal according to the groupcast feedback scheme.
