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

摘要

One embodiment of the present invention is a method for reporting channel state information by means of a terminal in a wireless communication system, the method comprising: a step of measuring a channel using at least one channel state information-reference signal (CSI-RS) indicated by at least one feedback type index from among a plurality of feedback type indices; and a step of generating channel state information based on the channel measurement and reporting the channel state information. Each of the plurality of feedback type indices indicates one or more CSI-RS configurations to be used in channel estimation and an effective channel relating to said one or more CSI-RS configurations.

主权项

1. A method for reporting channel state information by a user equipment (UE) in a wireless communication system, the method comprising:
receiving information comprising a channel state information (CSI) request field; and performing an aperiodic CSI report triggered by the CSI request field, wherein the CSI request field indicates one of ‘no aperiodic CSI report is triggered’, ‘the aperiodic CSI report is triggered for a first set of CSI feedback type configured via radio resource control (RRC) signaling’, ‘the aperiodic CSI report is triggered for a second set of CSI feedback type configured via RRC signaling’, and ‘the aperiodic CSI report is triggered for a third set of CSI feedback type configured via RRC signaling’, and wherein at least one CSI feedback type in the first, second or third set of the CSI feedback type is associated with at least two channel state information-reference signal (CSI-RS) configurations.
