    摘要: A method for receiving control information by a User Equipment (UE) in a wireless communication system is provided. The method includes monitoring channel quality of a control channel, determining whether reconfiguration of the control channel is needed, based on the channel quality of the control channel, if the reconfiguration of the control channel is needed, requesting an evolved Node B (eNB) to reconfigure the control channel, and receiving the control information through the reconfigured control channel.

    摘要: An apparatus and a method for transmitting and receiving control information in a Multiple Input Multiple Output (MIMO) system are provided. A method of a base station for transmitting control information to a terminal in the MIMO system includes transmitting first control information for every transmission mode except for a Multiple-User (MU)-MIMO mode, to the terminal over a control channel of a subframe, and transmitting second control information for the MU-MIMO mode to the terminal over a data channel of the subframe.

    摘要: Disclosed is an apparatus and method for transmitting/receiving a control message in a wireless communication system that is designed to reduce overhead associated with transmission/reception of the control message. To this end, a transmission apparatus generates a control message, generates a compressed control message by compressing the generated control message, based on a control message that has been lastly received by a reception apparatus from among previously transmitted control messages, selects one of the generated control message and the generated compressed control message according to whether or not the control message lastly received by the reception apparatus exists, and transmits the selected one of the generated control message and the generated compressed control message to the reception apparatus. Therefore, it is possible to reduce resources used for control message transmission, and thus increase the use efficiency of the resources.

    摘要: A method and apparatus change resource allocation to reduce overhead in a mobile communication system. The method of operating a base station for changing a fixed resource allocation to reduce overhead in a mobile communication system includes determining whether a plurality of fixed resource allocations collide in a fixed resource allocation period. If the fixed resource allocations collide, at least one fixed resource allocation among the plurality of fixed resource allocations is cancelled in the fixed resource allocation period and a determination is made on whether to reallocate the at least one fixed resource allocation before a next fixed resource allocation period. If the at least one fixed resource allocation is reallocated before the next fixed resource allocation period, a control message containing reallocation information changed with respect to the at least one fixed resource allocation is transmitted to a corresponding mobile station. Accordingly, a location of an allocation resource region based on a fixed resource allocation can be effectively changed by using minimum control information.

    摘要: An apparatus and method for supporting Hybrid Automatic Repeat reQuest (HARQ) in a broadband wireless communication system are provided. A method of performing HARQ by a Mobile Station (MS) in a wireless communication system includes receiving a control message including resource allocation information, decoding the control message, if the decoding is successful, determining whether a previous control message is lost, and if the previous control message is lost, transmitting one of a null signal and a specific indicator through a response channel.
