METHOD FOR RANGING WITH ACCESS POINT AND REPEATER IN WIRELESS COMMUNICATION SYSTEM

摘要

A repeater and a ranging method using the same in a mobile communication system are provided to prevent a loss of a ranging code and improve a call connection rate and the performance of periodical ranging. When a repeater transmits a message informing about initialization to a base station transmits a repeater initialization message to the repeater(S100). The repeater randomly selects an arbitrary ranging code among a plurality of ranging codes included in the message(S110) and transmits corresponding information to the base station(S120). The base station measures a timing offset and a power offset of the repeater by using the received ranging code and stores a result value(S130). The base station transmits the stored timing offset and power offset values included in a ranging code response message to the repeater(S140). The repeater stores the timing offset and power offset based on the values included in the received message(S150).
