FIELD: radio engineering, communication.
SUBSTANCE: group of inventions relates to a wireless communication system using orthogonal frequency-division multiple access. In a base station (100), a transmission processing unit (104) transmits, in one of a plurality of formats, control information containing a request to send a sounding reference signal (A-SRS), and a reception processing unit (108) receives the transmitted A-SRS using the resource specified by the format of the transmitted control information. Then, the plurality of formats is associated with each different SRS resource by a setting unit (101).
EFFECT: device is designed for flexible configuration of resources used to transmit reference signals.
