Abstract: The present disclosure relates to a method, performed by a user equipment (UE), for reporting channel state information (CSI) in a wireless communication system and an apparatus therefor. According to the present disclosure, the UE receives a channel state information reference signal (CSI-RS) from a base station through a multiple antenna port; and reports the CSI to the base station, wherein the CSI includes a precoding matrix indicator for a codebook generated by linear combination, wherein the codebook is generated based on a specific parameter set, and wherein the specific parameter set is differently set/applied based on at least one of a rank value or at least one layer index of a specific rank.

Abstract: The present specification provides a method for reporting channel state information in a wireless communication system. More specifically, a method performed by a terminal comprises: calculating, on the basis of a first CSI-RS and a second CSI-RS received from a first base station and a second base station, a first parameter related to a channel state of a first resource and a second parameter related to a channel state of a second resource or a third parameter related to a channel state of a specific resource; and reporting the first parameter and the second parameter or the third parameter to the first base station and the second base station, wherein when the third parameter is calculated, the third parameter is calculated by using a codebook related to the specific resource. In addition, CSI-RS density, a CDM setting value, a power control offset value, and a QCL are independently configured for each of a first antenna port for transmitting the first CSI-RS and a second antenna port for transmitting the second CSI-RS.
