Method for reporting channel state information in a wireless communication system, and apparatus therefor

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus for reporting channel state information, wherein the method comprises the following steps: receiving configuration information for periodically reporting channel state information; and periodically reporting the channel state information for a each of a plurality of periods based on the configuration information, wherein the channel state information is repeated so as to have a predetermined pattern based on periods, of which a second period is longer than a first period. The second period has a first value in a single transmission point operation mode. The second period has a sum of the first value and a second value which is proportional to the number of coordinated transmission points involved in a coordinated multi-point transmission operation in a coordinated multi-point transmission operation mode.

1. A method for reporting channel state information at a UE in a wireless communication system, the method comprising:
receiving configuration information for periodically reporting channel state information; and periodically reporting first channel state information related to a coordinated multi-point at a first period and second channel state information related to a serving-point at a second period based on the configuration information, wherein the second period is longer than the first period, wherein the second period is set to a first value in a single point transmission mode, wherein the second period is set to a sum of the first value and a second value in a coordinated multi-point transmission mode, and wherein the second value is proportional to the number of coordinating transmission points involved in the coordinated multi-point transmission.
