METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING SIGNALS OF TERMINAL AND BASE STATION IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2022/025330

Kind Code:

A1

Abstract:

Disclosed are an operation method of a terminal and a base station and a device supporting same in a wireless communication system. According to an example disclosed herein, the operation method of a terminal in a wireless communication system may comprise the steps of: receiving information about a modulation scheme from a base station; modulating effective transmission bits into an effective transmission symbol on the basis of the information about the modulation scheme; and transmitting the effective transmission symbol to the base station, wherein the effective transmission symbol can be transmitted on the basis of a phase rotation value indicated by a constellation phase rotation index indicator indicating the degree of phase rotation of a constellation axis.
