Abstract
An apparatus and method is disclosed for frequency reuse to avoid interference between a Relay Station (RS) and a Mobile Station (MS) in a multi-hop relay system. The method includes measuring a preamble signal strength of a serving RS, measuring a preamble signal strength of a neighboring RS, and computing a preamble signal strength ratio using the preamble signal strength of the serving RS and the preamble signal strength of the neighboring RS.
