Title:
METHOD FOR TRANSMITTING/RECEIVING UPLINK SIGNAL OF HIGH FREQUENCY BAND IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/251511
Kind Code:
A1
Abstract:
Presented are a method for transmitting/receiving an uplink signal of a high frequency band in a wireless communication system, and a device therefor. Particularly, a method performed by means of a reflection device comprises the steps of: transmitting, to a base station, signal information including information about reception strength and information about a reception angle, on the basis of a synchronization signal of a low frequency band from a terminal; receiving, from the base station, beam pattern information for controlling a reflection beam of a high frequency band, on the basis of the signal information; and transmitting, to the base station, an uplink signal of the high frequency band received from the terminal, on the basis of the reflection beam of the high frequency band.
