Abstract
According to the present specification, a method for reporting channel state information (CSI) in a wireless communication system, which is performed by a UE includes: transmitting to a base station UE capability information including control information indicating a codebook configuration supported by the UE with respect to a specific class related with the CSI reporting. Therefore, there is an effect that implementation complexity of the UE can be reduced.

A method for reporting channel state information (CSI) in a wireless communication system, which is performed by a user equipment (UE), the method comprising:
- transmitting, to a base station UE capability information including control information indicating a codebook configuration supported by the UE with respect to a specific class related to the CSI reporting;
- receiving CSI process related information including CSI-reference signal (RS) configuration information from the base station through a higher layer signaling;
- receiving at least one CSI-RS from the base station based on the received CSI process related information, the at least one CSI-RS being transmitted through at least one CSI-RS port;
- measuring a channel based on the at least received CSI-RS;
- and
- reporting the channel measurement result to the base station.
A user equipment (UE) for reporting channel state information (CSI) in a wireless communication system, the UE comprising:
- a radio frequency (RF) module for transmitting and receiving a radio signal;
- and
- a processor controlling the RF module,
- wherein the processor controls to:
- transmit to a base station UE capability information including control information indicating a codebook configuration supported by the UE with respect to a specific class related with the CSI reporting,
- receive CSI process related information including CSI-reference signal (RS) configuration information from the base station through a higher layer signaling,
- receive at least one CSI-RS from the base station based on the received CSI process related information,
- the at least one CSI-RS being transmitted through at least one CSI-RS port,
- measure a channel based on the at least received CSI-RS, and
- report the channel measurement result to the base station.
