Scanning apparatus and method in a multi-hop relay broadband wireless access communication system

摘要

A scanning apparatus and method in a multi-hop relay Broadband Wireless Access (BWA) communication system are provided. In the scanning method, a Mobile Subscriber Station (MSS) sends a scan request message requesting scanning to a Base Station (BS) via a Relay Station (RS). The BS sends a scan response message containing information for the scanning of the MSS to the MSS via the RS. The BS then sends a scan notify message indicating the scanning of the MSS to the RS.
