Title:

METHOD FOR TRANSMITTING/RECEIVING UPLINK CHANNEL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR

Document Type and Number:

WIPO Patent Application WO/2018/128376

Kind Code:

A1

Abstract:

Disclosed are a method for transmitting/receiving an uplink channel in a wireless communication system, and a device therefor. Specifically, a method for a terminal transmitting an uplink channel comprises the steps of: receiving a specific reference signal (CSI-RS) from a base station; determining the number of beams for transmitting an uplink control channel for reporting uplink control information generated on the basis of the CSI-RS; and transmitting the uplink control channel to the base station via a single beam or a plurality of beams according to the determined number of beams, wherein the number of beams may be determined on the basis of at least one among measurement information by a downlink reference signal received from the base station, or the type of the uplink control information.
