Abstract: A system and a method for transmitting and receiving data in a communication system are provided to minimize the power consumption of an MS(Mobile Station) by using a downlink scheduling scheme and an uplink power control scheme when the MS is in a battery shortage state. An MS in a dormant or idle state compares its residual battery capacity with a preset threshold. If it is confirmed that the residual battery state is smaller than or equal to the preset threshold(405), the MS transmits a MOB_LBAT_IND(Mobile Lack Battery Indication) message to a BS(Base Station)(407). Receiving the MOB_LBAT_IND message, the BS judges that the MS is in a battery shortage state(409), and transmits a MOB_LBAT_ACK(Mobile Lack Battery Acknowledgement) message to the MS(411). Receiving the MOB_LBAT_ACK message, the MS transits to the battery shortage state(413).

Abstract: An apparatus and a method for allocating uplink radio resources in a broadband wireless communication system are provided to allocate uplink radio resources for multi-hop to reduce delay in uplink resource allocation of a relay station for real time traffic and achieve efficient resource management of a base station. In an operation of a relay station to allocate uplink radio resources in a broadband wireless communication system, a resource request message received from a terminal is relayed to a base station(408). Data is received from the terminal(412). When the received data corresponds to non real time traffic, the data is classified by traffics and queued. The queue state is confirmed and the base station is requested to transmit required radio resources(410).

Abstract: An apparatus and a method for performing an effective automatic repeat request in a multi-hop relay system are provided to enhance a throughput by reflecting characteristics of each of hobs. A determination process is performed to determine whether a terminal enters into a handover region or not. When the terminal enters into the handover region, an E2E(End-to-End) ARQ(Automatic Repeat reQuest) message(301) is transmitted to a relay station or a terminal, an ARQ block to the terminal is transmitted to the relay station, and the ARQ block is stored in a queue. An ACK for the block is received from the relay station. When an E2E ACK(303) is received from the relay station or the terminal in order to indicate the corresponding ARQ block of the terminal, the corresponding ARQ block is scrapped in the queue.

Abstract: An apparatus and a method for RS(Relay Station) handover in a multi-hop relay wireless communication system are provided to offer a seamless service by reducing a packet transmission delay due to the RS handover of a mobile station as an estimated target RS receives the same data packet as a serving RS. A base station in a multi-hop relay wireless communication system comprises an activecasting control part(325), a scheduler(329), and a transmitting part. The activecasting control part judges whether activecasting is required for a mobile station. In case the activecasting control part decides to execute activecasting for the mobile station, the scheduler allocates resources in consideration of the mobile station's channel state with a serving RS. Using the allocated resources, the transmitting part multicasts a Tx packet, which will be transmitted to the mobile station, to a target RS and the serving RS.

Abstract: An apparatus and a method for determining a data rate in a multi-hop relay system are provided to buffer data stably to be transmitted to a next frame by a relay station, thereby reducing jitter due to length change of the relay station and reducing resource consumption between the relay station and a base station. An apparatus for determining a data rate in a multi-hop relay system includes a receiver, a computation unit, and a scheduler. The receiver(900) receives queue length information and channel information related to a terminal from a relay station. The computation unit(904) determines a transmission rate between a base station and a relay station related to data of a terminal using the channel information and the queue length information. The scheduler(906) performs resource scheduling related to communication between the base station and the relay station using the transmission rate from the computation unit.
