Abstract: PURPOSE: A location estimation method of terminal and apparatus thereof are provided to receive a location base service in the downtown area through a PRS reception apparatus without having a GPS reception apparatus. CONSTITUTION: A candidate set list selected from E- SMLC(Evolved-Serving Mobile Location Center)(100) is received and determines a candidate location. A terminal(130) receives resource allocation information from a serving base station(120c) of a determined candidate location and shares with an uplink signal. Each base station including the serving base station receives the uplink signal through a relay. Received uplink signals are combined. The uplink signal of a target terminal determines a signal from a combining result. The location of the terminal is examined by a determined result.

Abstract: PURPOSE: A device and a method for obtaining neighbor BS information in a wireless communication system are provided to minimize an L2 scanning interval for obtaining adjacent base station information from a terminal. CONSTITUTION: A terminal determines whether to execute L2 scanning in consideration of an L1 scanning result(301). The terminal detects a P-SFH(Primary-Super Frame Header) of a neighbor BS(Base Station) through the L2 scanning(303). The terminal checks transmission timing of SFH for transmitting SPx through an SFN(Super Frame Number) of the neighbor BS(305). The terminal selectively obtains L2 information of the neighbor BS through the L2 scanning for the neighbor BS at only the transmission timing of the SFH(307).
