Title:
METHOD FOR TRANSMITTING OR RECEIVING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/034341
Kind Code:
A1
Abstract:
Disclosed are a method for transmitting or receiving channel state information in a wireless communication system and a device therefor. Specifically, a method for transmitting channel state information (CSI) by a terminal in a wireless communication system may comprise the steps of: receiving, from a base station, the number of antenna ports specific to one or more channel state information-reference signal (CSI-RS) resources; receiving, by the terminal, a CSI-RS on the one or more antenna ports from the base station; when the number of one or more CSI-RS resource-specific antenna ports configured in the terminal is different from the number of antenna ports in reporting units of the CSI configured in the terminal, estimating a CSI-RS antenna port on the basis of the number of antenna ports in reporting units of the CSI configured in the terminal, and deriving the CSI on the basis of the CSI-RS; and reporting the CSI to the base station.
