Abstract: The present invention relates to a method and an apparatus for controlling priority in device-to-device communications. A plurality of transmission resources are classified into resource index sets depending on indexes, and a priority given to a communication object to which a device communication is applied is determined. One resource index set is allocated to a device of the communication object depending on the priority of the communication object.

Abstract: A base station determines whether a reception of each uplink signal transmitted by a plurality of terminals succeeds. The base station generates a response bit map representing whether the reception succeeds. Further, the base station transmits first downlink control information (DCI) including the response bit map to the plurality of terminals through a first downlink control channel.
