摘要： An apparatus and method for simultaneous transmission scheduling in a multi-hop cellular system are provided, in which a base station presets simultaneous transmission relay station set information and transmits the simultaneous transmission relay station set information to relay stations managed by the base station, and an relay station receives the simultaneous transmission relay station set information from the base station, determines, upon receipt of a data frame from the base station, a state of the relay station preset in relation to a receiving relay station for the data frame by comparing an ID of the receiving relay station included in the data frame with the simultaneous transmission relay station set information, and operates according to the preset state.

摘要： A handoff method in a communication system where BSs providing different radio access interfaces to an MS are connected to an IP-based network through routers. A handoff from a first BS to a second BS is decided for an MS that receives IP service data from the first BS and an L2 connection is established between the MS and the second BS. During the L2 connection establishment, movement of the MS in the IP network is detected. Handoff negotiations are conducted between the first and second BSs by IP signaling. If the handoff is available according to the negotiations, mobility management control is performed considering movement of the MS. The IP service data is transmitted to the MS in a network path reset to the second BS by the mobility management control and an L2 connection is released between the MS and the first BS.

摘要： An apparatus and method for transmitting/receiving resource allocation information in a communication system are provided. In the method of transmitting resource allocation information, at least one of a plurality of FDD UL FA resources is divided into a plurality of segment regions, and first resource allocation information is transmitted to mobile stations through a plurality of TDD DL FA resources. The first resource allocation information indicates, among the plurality of segment regions, each of segment regions corresponding to the TDD down link FA resources.

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.
