摘要： The present invention relates to a channel quality information transmission method in a communication system adopting a coordinated multi-point scheme. A terminal receives signals, through the same band, from a serving base station and at least one neighbor base station, respectively, which are included in a CoMP set operating in a joint processing mode. Next, the terminal generates combined channel quality information on a single signal obtained by combining the signals received through the same band, and then transmits the information to the serving base station. The combined channel quality information is generated using information on a combined channel obtained by combining channels between the terminal and the serving base station and between the terminal and each one of the at least one neighbor base station, which are included in the CoMP set.

摘要： Disclosed are a method for estimating a channel state in a CoMP operation of a terminal and a method for generating channel state information of a base station. A terminal can measure strength or an interference level of a signal of each cell using a reference signal received from each cell for performing the CoMP operation. In addition, the terminal can measure the sum of the interference levels of the cells which do not perform the CoMP operation using a region from which a reference signal of a serving cell of each cell is transmitted. In addition, the terminal can transmit to the serving base station the strength of the interference level of the signal of each cell for performing the measured CoMP operation and the sum of the interference levels of the cells which do not perform the CoMP operation.

摘要： The present invention relates to a wireless communication system having at least one base station utilizing CoMP (Coordinated Multi-Point) transmission, wherein a terminal receives a reference signal from said at least one base station. If said at least one base station makes a transmission based on said reference signal through Coordinated beamforming (CB), information based on PMI (Precoding Matrix Index) corresponding to each base station is determined. Accordingly, if said at least one base station makes a transmission based on joint processing, phase set information is determined for phase correction of the formed beam. Thus, the present method transmits feedback information, comprising PMI set information based on CB and said phase set information, from said at least one base station to a server base station.
