COOPERATIVE MULTI-ANTENNA TRANSMITTING AND RECEIVING METHOD AND APPARATUS FOR MOBILE COMMUNICATION SYSTEM, AND METHOD FOR CONFIGURING CLUSTER FOR THE SAME

摘要

A target terminal in a mobile communication system transmits a first uplink cooperative MIMO signal in a first uplink subframe to a cooperating device selected from among a plurality of repeaters for relaying signals and a plurality of terminals except a target terminal for cooperative MIMO transmission and reception, and transmits a second uplink cooperative MIMO signal directly in a second uplink subframe to a base station. The cooperating device amplifies the first uplink cooperative MIMO signal and transmits an amplified first uplink cooperative MIMO signal in the second uplink subframe to the a base station.

1. A cooperating cluster configuring method for a cooperative MIMO (Multiple-Input Multiple-Output) transmission and reception in a base station of a mobile communication system, the method comprising:
selecting a plurality of candidate cooperating devices to cooperate for the cooperative MIMO transmission and reception from among a plurality of repeaters for relaying signals and a plurality of terminals except a target terminal for cooperative MIMO transmission and reception; selecting at least one cooperating device from among the plurality of candidate cooperating devices based on signal quality information measured between the plurality of candidate cooperating devices and the target terminal; generating a cooperating cluster including the at least one cooperating device; and transmitting configuration information of the cooperating cluster to the target terminal.
