摘要：
Ranging by a mobile station in a legacy support mode is disclosed. According to embodiments of the present invention, S-SFH information transmitted by a base station in a system operating in FDM based uplink mixed mode is configured in a manner different from that of the FDM based uplink mixed mode. And, a mobile station performs a ranging by interpreting S-SFH differently according to a presence or non-presence of the mixed mode. Therefore, the present invention efficiently manages the ranging of the mobile station and reduces unnecessary signaling overhead.
