communication method using a relay station in a mobile communication system

METHOD OF COMMUNICATION USING relay STATION IN A MOBILE COMMUNICATION SYSTEM. The present invention describes a method decomunicacao using a relay station (RS) in a mobile communication system. A base station transmits identification information, which designates a position of a region of relay station for at least one next frame to a mobile subscriber station by the relay station and the mobile subscriber station identifies the position of the relay station region during at least one next frame. Thus, the mobile subscriber station does not need to synchronize with a relay station preamble to retrieve the region deestacao relay for every frame, and a start point of the relay station region can be recovered quickly and precisely even in the case where the position of the relay station region is varied.
