Title:
METHOD FOR CHANNEL STATE REPORTING IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME
Document Type and Number:
WIPO Patent Application WO/2018/128340
Kind Code:
A1
Abstract:
A method for channel state information-reference signal (CSI-RS)-based channel state reporting in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving a CSI-RS-related configuration from a base station; calculating CSI by measuring a CSI-RS according to the CSI-RS-related configuration; and transmitting the calculated CSI to the base station, wherein the CSI-RS-related configuration comprises configurations for different types of CSI-RSs, and when at least two different types of CSI-RSs are configured to be transmitted in the same resource, a terminal measures only a CSI-RS having a predetermined higher priority.
