Apparatus and method for selecting relay station using relay station preamble signal in a multi-hop relay broadband wireless access communication system

摘要

An apparatus and method for selecting an RS using an RS preamble signal in a multi-hop relay BWA communication system are provided, in which a BS sends preamble channel allocation information to at least one RS, the at least one RS sends a preamble to an MS according to the preamble channel allocation information, the MS measures the signal strength level of the preamble received from the at least one RS and reports the signal strength level to the BS, and the BS selects an RS for providing a relay service to the MS according to the signal strength level.
