Title:
METHOD AND APPARATUS FOR TRANSMITTING CHANNEL STATE INFORMATION
Document Type and Number:
WIPO Patent Application WO/2019/221542
Kind Code:
A1
Abstract:
The present embodiments may provide a technique of transmitting, by a terminal, channel state information with regard to one or more beams to a base station. The present embodiments provide a method and an apparatus for transmitting, by a terminal, channel state information with regard to one or more beams, the method comprising the steps of: receiving CSI reporting configuration information from a base station; determining whether or not group-based beams are to be reported on the basis of the CSI reporting configuration information; measuring RSRP with regard to CSI-RS received through one or more CSI-RS resources; and transmitting, to the base station, channel state information including values on a predetermined table on the basis of the group-based beam reporting and the CSI-RS RSRP measurement results.
