A determination of link quality (CSR) is made from the subscriber station to a relay station. A determination of link quality (CRB) is made from the relay station to the base station, and a determination of link quality (CSB) is made from the subscriber station to the base station. A quality of a first link path from the subscriber station to the base station that passes through the relay station is determined based on at least the link qualities (Csr, Crb). A quality of a second link path from the subscriber station to the base station that does not pass through the relay station is determined based on at least the link quality (Csb). Finally, a determination is made whether to utilize the first link path or the second link path from the subscriber station to the base station based on at least the quality of the first and second link paths.
