Abstract:
A method for efficiently transmitting and receiving downlink control information is disclosed. The method includes, at a base station, receiving feedback information including a precoding matrix index (PMI) from a user equipment (UE) and transmitting precoding information having a predetermined bit number according to the number of antenna ports and a transmission mode of the base station. The precoding information of a predetermined transmission mode in the precoding information includes confirmation information indicating that the base station uses a PMI which is recently received from the UE.
