20160007340 | METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR - A method for reporting channel state information (CSI) in a wireless communication system and an apparatus therefor are disclosed. According to an example of the present invention, a method in which a terminal transmits CSI in a wireless communication system may comprise: a step of receiving data about a feedback antenna port configuration from a base station; and a step of transmitting CSI regarding K (K≧1) feedback antenna ports from each of N (N≧2) reporting resources to the base station. The K feedback antenna ports may be a part of M (M≧2) antenna ports. The CSI regarding K feedback antenna ports may include phase information about the K feedback antenna ports. The phase information about the K feedback antenna ports may be determined by assuming a phase difference with respect to a reference antenna port. | 01-07-2016 |
