Abstract: Systems, base stations, terminals, and methods for group-selective channel feedback in a wireless communication system are described. In one signal measurement method for a base station supporting Multiuser Multiple-Input Multiple-Output (MU-MIMO), the base station allocates a group identifier to a terminal group for performing and reporting signal measurements simultaneously. When the base station transmits control information including the group identifier, each one of terminals belonging to the terminal group performs signal measurement, generates signal measurement feedback, and simultaneously transmits the signal measurement feedback to the base station.
