Method for reporting channel state information in 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 a terminal to report channel state information in a wireless communication system, the method comprising: a step of transmitting first channel state information according to a first channel state information (CSI) process for reporting the first channel state information periodically for every first period; a step of transmitting second channel state information according to a second CSI process for reporting the second channel state information periodically for every second period; and a step of dropping the transmission of either the first channel state information or the second channel state information on the basis of the CSI process index of each of the first and second CSI processes in the event the first channel state information transmission timing and the second channel state information transmission timing conflict.

1. A method for reporting channel state information (CSI) in a wireless communication system, the method comprising:
transmitting first CSI according to a first CSI process of periodically reporting the first CSI every first period; transmitting second CSI according to a second CSI process of periodically reporting the second CSI every second period; and dropping transmission of one of the first CSI and second CSI based on a specific rule when transmission timing of the first CSI and transmission timing of the second CSI collide and the first CSI and the second CSI have a same transmission priority, and the first CSI process and second CSI process are CSI processes of a same serving cell, wherein the specific rule is defined as dropping a CSI except for a CSI corresponding to a CSI process with a lowest CSI process index from the first CSI and second CSI.
