Abstract: A wireless communication method for efficiently managing a bandwidth request of a terminal and an allocation procedure and a system thereof are provided to operate an RS system in two modes in consideration of a case that an MS directly transmits a BR code to an MR-BS, thereby improving system performance while satisfying existing standards. It is monitored whether an uplink map information element corresponding to a BR(Bandwidth Request) code of an MS(Mobile Station) is received from an MR(Mobile Relay)-BS(Base Station)(S402). The RS monitors an uplink burst having a bandwidth that the MS requests is transmitted from the MR-BS based on the uplink map information element. Data that the MS transmits is relayed to a band allocated by the uplink burst from the MR-BS.

Abstract: An initial ranging method, an access terminal, and a repeater in a communication system are provided to prevent both of the repeater and a base station from succeeding in initial ranging when a terminal in a location, where a repeater region and a base station region are overlapped, attempts initial ranging, thereby preventing the base station from allocating resources duplicatedly. An AT(Access Terminal)(110a) a broadcasting message including a DL-MAP(Downlink MAP) message, an UP-MAP(Uplink MAP) message, a DCD(Downlink Channel Descript) message, a UCD(Uplink Channel Descript) message, and a AP NBR-ADV(Access Point Neighbor-Advertisement) message to an AP(120) and a repeater(140) if system synchronization is acquired between the AP and the AT(S600,S602). The AT generates an initial ranging code using a Cell_ID(Identification) to attempt the initial ranging of the AP and the repeater(S604,S604'). The AP displays and broadcasts initial ranging code information and a power offset control value transmitted from the AT to a RNG-RSP(Ranging Response) message(S606). The AT checks the initial ranging code information, controls power offset, and reattempts initial ranging when the status field of the RNG-RSP message is 'continue'(S608). The AP displays the status field of the RNG-RSP message into 'success' and transmits the RNG-RSP message(S610). The AP allocates an uplink section to the AT through the UL-MAP having CDMA_Allocation_IE(Code Division Multiple Access_Allocation_IE)(S612). The AT can transmits the RNG-RSP message in the allocated uplink section.

Abstract: An access-uplink power control method and system using a mobile multi-hop relay are provided to allow a multi-hop relay base station to control power at a high speed in consideration of the entire cell by using a power control value previously corrected by a mobile multi-hop relay. A base station(100) determines one of a method for directly controlling an access-uplink and a method for controlling power of the access-uplink by a relay(110) in consideration of a power control state of the entire cell(S200). If the base station determines the former method, the relay measures channel quality with respect to the access-uplink(S210) and transmits channel quality measurement information together with a basic CID(Caller ID) to the base station(S220). The base station measures reception power with respect to a relay-uplink, generates a message for controlling power of the access-uplink based on the channel quality measurement information(S230), and transmits the message to a terminal(120) by way of the relay(S240). The terminal immediately reflects a power correction value included in the received power control message on a transmission power gain(S250). If the base station selects the method for directly controlling power of the access-uplink by the relay(S200), the base station informs the relay about the determined method(S260). The relay measures channel quality with respect to the access-uplink(S270), and includes a power correction value calculated based on the measurement result in a power control message, and transmits the same to the terminal(S280).
