    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: An apparatus and a method for a cluster-based power control at a macro base station in a wireless communication system are provided. The method includes broadcasting an interference allowance value determined based on a predefined aggregate interference to a femto cell, updating the interference allowance value with consideration of a channel activity for each femto cell group on a cluster basis, and when detecting a change in an aggregate interference generated due to femto cell power allocation, repeating determination of an interference allowance value so that a Quality of Service (QoS) of a macro cell user is met, and broadcasting the interference allowance value to a femto cell.

    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: A method for feeding back Channel Quality Information (CQI) by a terminal in a Multi-User Multi-Input Multi-Output (MU-MIMO) communication system is provided. The method includes receiving a signal from a base station, determining a lower limit of an average Signal to Interference plus Noise Ratio (SINR) for the received signal, and determining the lower limit of an average SINR as CQI, and feeding back the CQI to the base station.
