Title:
SIGNAL TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/011258
Kind Code:
A1
Abstract:
The present application provides a signal transmission method and apparatus, which can not only realize multi-user phase noise compensation, but also reduce a PAPR of a signal and improve signal transmission performance, and can be applied to a communication system. The method comprises: a terminal acquires first information, and sends a signal corresponding to a first pilot pattern or a second pilot pattern. The first information is used for indicating that the terminal uses the first pilot pattern or the second pilot pattern; the first pilot pattern is used for indicating that a first reference signal is located at a first time domain position and a second reference signal is located at a second time domain position; the second pilot pattern is used for indicating that a third reference signal is located at the first time domain position and a fourth reference signal is located at a third time domain position. A time domain interval between the first time domain position and the second time domain position is smaller than or greater than a time domain interval between the first time domain position and the third time domain position. A corresponding value of the first reference signal in a first precoding sequence is opposite to a corresponding value of the third reference signal in a second precoding sequence.
