Abstract
Disclosed are a method for transmitting and receiving channel state information in a wireless communication system and an apparatus therefor. Specifically, a method for transmitting, by a terminal, channel state information (CSI) in a wireless communication system comprises the steps of: receiving a CSI process setting from a base station; and reporting, to the base station, CSI corresponding to a CSI process set by the CSI process setting, wherein when the CSI process is set to a beamformed CSI-reference signal (CSI-RS) type, and the CSI process is associated with a single CSI-RS resource, a codebook used for deriving the CSI may be indicated by the CSI process setting.
Claims12
A method for transmitting channel state information (CSI) by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving a CSI process configuration from a base station (BS);
- and
- reporting CSI corresponding to a CSI process configured by the CSI process configuration,
- wherein when the CSI process is configured as a beamformed CSI-reference signal (CSI-RS) type and the CSI process is associated with a single CSI-RS resource, a codebook used for deriving the CSI is indicated by the CSI process configuration.
A user equipment (UE) transmitting channel state information (CSI) in a wireless communication system, the UE comprising:
- a radio frequency (RF) unit for transmitting and receiving a radio signal;
- and
- a processor for controlling the RF unit,
- wherein the processor is configured to:
- receive a CSI process configuration from a base station (BS);
- and
- report CSI corresponding to a CSI process configured by the CSI process configuration,
- wherein when the CSI process is configured as a beamformed CSI-reference signal (CSI-RS) type and the CSI process is associated with a single CSI-RS resource, a codebook used for deriving the CSI is indicated by the CSI process configuration.
