A method for transmitting channel state information to a plurality of transmission points by a user equipment in a wireless communication system, the method comprising: receiving a configuration for channel state information reporting; and selecting at least one subband to report channel state information for each of a first transmission point and a second transmission point according to the configuration for channel state information reporting, wherein the configuration for channel state information reporting includes information as to whether a subband for the first transmission point is to be identically selected with a subband for the second transmission point, wherein when a selected subband for the first transmission point is different from a selected subband for the second transmission point, the user equipment reports information about subband selection for the first transmission point and the second transmission point by using subband selector bits for each transmission point, wherein when all the selected subbands for the first transmission point are the same with all the selected subbands for the second transmission point, the user equipment reports information about subband selection for the first transmission point only and reports channel phase and amplitude information of the first transmission point and the second transmission point by using the subband selector bits otherwise used to report information about subband selection for the second transmission point, and wherein the channel phase and amplitude information of the first transmission point and the second transmission point correspond to channel phase and amplitude information of two ports, respectively, the two ports being selected from among reference signals, RSs, used for channel estimation of each transmission point. receiving a configuration for channel state information reporting; and selecting at least one subband to report channel state information for each of a first transmission point and a second transmission point according to the configuration for channel state information reporting, wherein the configuration for channel state information reporting includes information as to whether a subband for the first transmission point is to be identically selected with a subband for the second transmission point, wherein when a selected subband for the first transmission point is different from a selected subband for the second transmission point, the user equipment reports information about subband selection for the first transmission point and the second transmission point by using subband selector bits for each transmission point, wherein when all the selected subbands for the first transmission point are the same with all the selected subbands for the second transmission point, the user equipment reports information about subband selection for the first transmission point only and reports channel phase and amplitude information of the first transmission point and the second transmission point by using the subband selector bits otherwise used to report information about subband selection for the second transmission point, and wherein the channel phase and amplitude information of the first transmission point and the second transmission point correspond to channel phase and amplitude information of two ports, respectively, the two ports being selected from among reference signals, RSs, used for channel estimation of each transmission point.
