Abstract

A cooperative communication method for cooperative communication with a user equipment by using a plurality of cells and a base station used for the cooperative communication are disclosed. The method for performing a cooperative communication for a user equipment by using a plurality of cells includes: comparing channel state information for a radio signal with a predetermined threshold value to thereby produce a comparison result; determining whether to perform the cooperative communication for the user equipment based on the comparison result; and transmitting a control message for cooperative communication to a cooperating cell which is to perform the cooperative communication.
