Abstract: A system for requesting the bandwidth request in a multi-hop relay communication system and a method therefor are provided to reduce the overhead and latency by enabling a relay station to request the bandwidth allocation for a plurality of CIDs by using one bandwidth request header, thereby improving the QoS gain. A relay station detects the initial_RS_CID(802), constructs a GBR_RS_CID_MAP including the bit value of the detected initial_RS_CID(804), forms a GBR header including the constructed GBR_RS_CID_MAP(806), and then transmits the formed result to a base station(808). The method for allocating a bandwidth in the base station comprises the following steps. The base station receives the GBR header from the relay station, decodes the GBR_RS_CID_MAP included within the GBR header, and then assigns an R-UL band for each RS_CID corresponding to the bit value set as 1 among bit values of the GBR_RS_CID_MAP.

Abstract: A system for allocating uplink resources in a communication system and a method thereof are provided to make a base station change and assign an uplink resource, which is exclusively assigned to a mobile station early, in case a mobile station requests it. If a base station detects the fact that it has to provide the service of a specific service quality class to a mobile station, it transmits the first uplink resource allocation information and then assigns the first uplink resource to the mobile station as an exclusive resource(613,615). The base station receives an uplink resource allocation request(617), and then checks whether the uplink resource to be assigned to the mobile station exists(619). If so, the base station transmits the second uplink resource allocation information and then assigns the second uplink resource to the mobile station as an exclusive resource(621,623). The base station release the first uplink resource allocation(625).

Abstract: An apparatus and a method for controlling power in a wireless communication system are provided to control idle mode and sleep mode of a mobile terminal. In case communications is not performed, a terminal(201) transmits the sleep require-message to the repeater station(203) in order to reduce the power loss(211). In case the sleep mode change over of the terminal is applied, the repeater station determines the management information in which the terminal operates to the sleep mode in consideration of the sleep mode management information which the terminal requests(213). The repeater station transmits the process time delay information of the sleep mode management information of the terminal and repeater station are transmitted to the base station(215). The base station transmits the sleep administration response message to the repeater station if the sleep management message is received without error(217).

Abstract: A PS(Power Saving) method and apparatus in a communication system are provided to control power of a terminal effectively by setting a PS priority level according to a combination of a remaining battery capacity and a QoS(Quality of Service) request degree of a previously received service. A terminal measures the remaining battery capacity(600), and discriminates a QoS request degree of a previously received service class(605). The terminal determines a PS priority level according to a combination of the remaining battery capacity and the QoS request degree(610), and sets a sleep window interval according to the determined PS priority level(615).

Abstract: A method and an apparatus for classifying packet data of each service flow in a communication system are provided to provide a service by service flows according to a service class included in an IP(Internet Protocol) header or a service label. When an IP packet arrives from an upper layer of a terminal, a classifier performs the first classification according to the first classification information of a header of the IP packet(500,502). The classifier checks whether the IP packet includes the second classification information(504). If the IP packet includes the second classification information, the classifier performs the second classification(506). The classifier checks whether detailed QoS(Quality of Service) information has been received from the upper layer(508). If there is detailed QoS information received from the upper layer, the classifier performs the third classification according to the detailed QoS(512) and transfers the IP packet together with a control message including the detailed QoS information to the second layer of the terminal.
