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: A method for managing a relay path in wireless communication environment is provided to optimize a path of a tree structure if a new RS enters an existing tree based network or a network topology is changed due to deterioration of quality of an existing link. A link quality report method of an RS(Relay Station) comprises the following steps of: grasping link quality of an RS and neighboring RSs; and transmitting a report message including the grasped link quality to a BS(Base Station). A path optimizing method for relay path management comprises the following steps. The BS calculates an optimum tree based on the link quality information included in the report message received from each RS(S550). The BS grasps a parent node of each RS based on the calculated optimum tree, and broadcasts a path setup message including information about the grasped parent node of each RS to the RSs(S555,S560). An RS, of which parent node has to be changed, performs an RS network reentry process for terminating connection with an existing parent node and connecting a new parent node(S565,S570).

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).
