    Abstract: Apparatus and method of providing transparent relay service to a Mobile Station (MS) in a multihop relay Broadband Wireless Access (BWA) communication system. The communication method includes checking, at at least one relay station (RS), a sounding channel allocated to an MS by analyzing a message broadcast from a Base Station (BS); measuring, at the BS, an BS-MS signaling level using a sounding signal of the MS, the sounding signal received in the sounding channel; measuring, at the at least one RS, an RS-MS signaling level using a sounding signal of the MS, the sounding signal received in the sounding channel; reporting, at the at least one RS, the RS-MS signaling level measurement value to the BS; and selecting, at the BS, an RS suitable for the MS using the BS-MS signaling level measurement value and at least one RS-MS signaling level measurement value reported from the at least one RS. Accordingly, the BS can select a suitable RS for the MS by taking into account the RS-MS channel status.

    Abstract: Provided are an apparatus and method for managing connection identifiers (CIDs) in a multi-hop relay Broadband Wireless Access (BWA) system. An apparatus is provided for a Relay Station (RS) in a multi-hop relay cellular communication system. The apparatus includes a database, a controller, and a transmitter. The database is used for managing a Connection Identifier (CID) set assigned to the RS by a Base Station (BS). The controller accesses the database to assign one CID of the CID set to a Mobile Station (MS) when receiving a control message from the MS. The transmitter constructs a response message including the CID assigned to the MS and transmits the response message to the MS. The MS can be assigned a CID directly from the RS in a condition that the BS is not involved, so that the initial ranging procedure can be rapidly performed.
