<p><P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for transmitting/receiving a reference signal, for positioning in a wireless communication system. <P>SOLUTION: A base station locates a primary advanced (PA) preamble in a second frame among frames constituting each of multiple superframes, locates a secondary advanced (SA) preamble in first symbols of first and third frames, determines multiple consecutive first superframes that belongs to a location-based service (LBS) zone, includes a reference signal for LBS in a first symbol of a first subframe of a last frame among frames constituting each of the first superframes. When data are to be transmitted, the base station includes the data in a first symbol of a first subframe of a last frame among the frames constituting each of second superframes excluding the first superframes, and communicates with a terminal by using the first and second superframes. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
