    摘要： 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.

    摘要： The present invention relates to a femtocell search method for a handover from a macrocell to a femtocell. The present invention relates to a method for a terminal that accesses a macrocell to search a femtocell in an environment where a plurality of femtocells are overlapped in one macrocell. The terminal searches a femtocell by using a dummy preamble in order to minimize the size of neighbor cell lists broadcasted from the macrocell to the terminal. Therefore, according to the present invention, an MAC overhead can be minimized by eliminating neighbor femtocell lists in a mobile neighbor advertisement (MOB_NBR_ADV) message broadcasted from the macrocell, and the terminal can search a femtocell with a minimum scanning load by checking only a femtocell dummy preamble in a dedicated symbol of the macrocell.
