METHOD AND DEVICE FOR TRANSMITTING SIGNAL

Document Type and Number:

WIPO Patent Application WO/2020/001485

Kind Code:

A1

Abstract:

The present application relates to the technical field of communications, and disclosed are a method and device for transmitting a signal. The method comprises: generating a first data signal on the basis of channel state information; receiving a second data signal transmitted by a master transmitter, and determining the phase of the second data signal; and transmitting the first data signal on the basis of the phase of a first measurement signal transmitted by the master transmitter and the phase of the second data signal. That is, a time delay difference between a detection time delay of the second data signal and a detection time delay of the first measurement signal can be obtained by means of the phase of the second data signal transmitted by the master transmitter and the phase of the first measurement signal transmitted when the master transmitter performs channel measurement. On this basis, a detection time delay in a joint transmission process of the master transmitter and a salve transmitter can be eliminated by transmitting the first data signal according to the phases of the two signals, thereby achieving time synchronization of the master transmitter and the slave transmitter.
