Title:

DATA TRANSMISSION METHOD, DATA RECEIVING METHOD, AND RELATED DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/161224

Kind Code:

A1

Abstract:

The present application discloses a data transmission method, a data receiving method, and a related device. The method comprises performing first phase rotation on modulation data to obtain time domain rotation data; performing frequency domain transformation on the time domain rotation data to obtain frequency domain data; performing second phase rotation on the frequency domain data to obtain frequency domain rotation data; performing time domain transformation on the frequency domain rotation data to obtain time domain data; and transmitting the time domain data. Therefore, on the basis an SC-FDMA waveform, the modulation data and the frequency domain data can be subjected to phase rotation, respectively, thereby reducing the maximum amplitude of the time domain data and reducing the PAPR of the transmitted time domain data.
