The method according to one embodiment includes receiving downlink transmissions in downlink subframes; and transmitting the ACK/NACK information for the downlink transmissions in one uplink subframe associated with the downlink subframes. The downlink subframes and the uplink subframe are configured for a time division duplex (TDD).
