APPARATUS AND METHOD FOR SCANNING IN A MULTI-HOP RELAY BROADBAND WIRELESS ACCESS COMMUNICATION SYSTEM

摘要

An apparatus and a method for scanning in a broadband wireless access communication system using multi-hop relay are provided to provides the same service and function between an MSS(Mobile Subscriber Station) and a BS(Base Station), reduce a difference between systems that may be caused by dual signaling between an RS(Relay Station) and the MSS and between the RS and the BS, and match synchronization of a system operation. A message processing unit(811) processes a scan request message received from an MSS. A message generating unit(813) generates a scan response message corresponding to a scan command message including a scanning guide from a BS. An interface module(821) transmits the message from the message generating unit via an antenna. The scanning guide is one of a terminal scan refusal, a terminal scan instruction, and a terminal scan notification. If the scanning guide is the terminal scan instruction, a scan command message including information about a scan schedule and a scan result report required for the MSS is received. If the scanning guide is the terminal scan refusal, a scan section is set as zero and a scan response message is transmitted to the MSS. A control unit(819) provides the message processing unit with a control message received from the MSS or the BS. In addition, the control unit receives a message which is supposed to be transmitted to the MSS or the BS, and then transmits the message to the interface module.
