    摘要： A data forwarding apparatus and method for reducing a HandOver (HO) interruption time in a wireless communication system where a macro cell and a femto cell coexist are provided. An operation method of a Mobile Station (MS) for data forwarding in a wireless communication system includes synchronizing with a serving Base Station (BS) after completing a HO procedure with a target BS, and receiving data packets existing in a queue through an air link directly from the serving BS.

    摘要： Provided is an apparatus and method for transmitting/receiving signals in a communication system. A base station allocates a quasi-dedicated control channel (QDCCH) to a first mobile station (MS), and allocates the QDCCH allocated to the first MS, to a second MS for a preset time. An MS receives a QDCCH allocated from the base station. If there is data to transmit to the base station, the MS determines whether the QDCCH is allocated to another MS different from the MS. If it is determined that the QDCCH is allocated to the MS itself, the MS transmits the data to the base station over the QDCCH.

    摘要： A technique for managing a packet to be transmitted to a Mobile Station (MS) that performs Relay Station (RS) handover in a multi-hop relay Broadband Wireless Access (BWA) system is provided. In the BWA system, a Base Station (BS) includes a controller for determining whether to perform activecasting on an MS upon receiving an activecast request message; a scheduler for allocating a resource by taking into consideration a channel condition between the MS and a serving RS when activecasting is determined to be performed; and a transmitter for multicasting a packet, which is to be transmitted to the MS, to a target RS and the serving RS by using the allocated resource.
