Title:
METHOD FOR TRANSMITTING AND RECEIVING UPLINK SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/160372
Kind Code:
A1
Abstract:
The present specification provides a method by which a terminal transmits an uplink signal in a wireless communication system. Particularly, the terminal scrambles a plurality of bits for transmission of an uplink signal, and generates a plurality of complex symbols by modulating the plurality of bits according to a specific modulation method. In addition, the terminal repetitively performs, a predetermined number of times, discrete Fourier transform (DFT) and inverse fast Fourier transform (IFFT) on at least one complex symbol of the plurality of complex symbols, and transmits the uplink signal, which is generated through the DFT and IFFT, to a base station, wherein the at least one complex symbol has a phase value which is increased or reduced as much as a specific value according to a symbol index.
