- Disclosed is a technique related to a method for controlling synchronization by correcting data transmission time or frequency offset, and to a station. According to the technique, a method for controlling the synchronization of a first terminal for data transmission/reception in a coordinated communication system comprises: a step of transmitting a first request frame and a second request frame containing transmission time information for each of a first response frame and a second response frame to a second terminal and to a third terminal, respectively; a step of receiving the first response frame and the second response frame from the second terminal and the third terminal; a step of estimating a first propagation delay time between the first terminal and the second terminal and a second propagation delay time between the first terminal and the third terminal, using the time of receiving the first response frame and the second response frame; and a step of transmitting, to the second terminal, a third request frame containing information on the delay time difference between the first propagation delay time and the second propagation delay time.
