US 2019/0356439 A1 · CSI-RS CONFIGURATION METHOD AND APPARATUS FOR BEAM MANAGEMENT IN WIRELESS COMMUNICATION SYSTEM

Abstract

According to one embodiment of the present disclosure, a method for determining a beam used in communication by a terminal in a mmWave communication system can be provided. The method for determining the beam may comprise a step of receiving CSI-RS from a base station, and a step of determining the beam on the basis of the CSI-RS. A CSI-RS resource and a CSI-RS port are determined on the basis of the CSI-RS, and the determined beam may correspond to the CSI-RS resource and the CSI-RS port.

Dependent claims

A method of determining a beam to be used for communication by a user equipment (UE) in a millimeter wave (mmWave) communication system, the method comprising:

receiving a channel state information-reference signal (CSI-RS) from a base station (BS);
and
determining the beam based on the CSI-RS;
wherein a CSI-RS resource and a CSI-RS port are determined based on the CSI-RS, and
wherein the determined beam corresponds to the CSI-RS resource and the CSI-RS port.
