Abstract: Methods and apparatuses are provided for wireless communication. A scheduling message is received that includes first information on at least one resource allocated for uplink transmission and second information. Data and a pilot are transmitted via the allocated at least one resource for uplink transmission. An ACK/NACK resource is identified based on a lowest index among at least one index of the allocated at least one resource for uplink transmission and the second information. An ACK/NACK signal is received in response to the transmitted data using the identified ACK/NACK resource.

Abstract: Disclosed is a method for transmitting a sounding reference signal (SRS) in a cooperative communication system. The method comprises receiving, from a macro base station, SRS resource information indicating transmission resources of an SRS to be transmitted by a user equipment (UE); transmitting the SRS and uplink data based on a UE-specific SRS subframe configuration included in the SRS resource information when the SRS resource information includes the UE-specific SRS subframe configuration information; and transmitting the SRS and the uplink data based on a pre-stored cell-specific SRS subframe configuration when the SRS resource information does not include the UE-specific SRS subframe configuration information. When a destination of the SRS to be transmitted by the UE is selected as a base station related to the macro base station, the SRS resource information includes the UE-specific SRS subframe configuration information of the base station selected as the destination of the SRS.
