Title:
SIGNAL SENDING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/029653
Kind Code:
A1
Abstract:
Disclosed in the present application is a signal sending method. The method comprises: a sending side sends a reference signal to a receiving side, the transmit power of the reference signal being P1; the sending side sends a data signal to the receiving side, the transmit power of the data signal being P2; the sending side again sends the reference signal to the receiving side, the transmit power of the retransmitted reference signal being P3, P3 being greater than P1, and an absolute value of a difference between P3 and P1 being Δ1; the sending side again sends the data signal to the receiving side, the transmit power of the retransmitted data signal being P4, P4 being greater than or equal to P2, an absolute value of a difference between P4 and P2 being Δ2, and Δ2 being less than Δ1. According to the method, by using a smaller power in an gradually-increasing step on a data signal, the interference due to the excessively-great transmit power of the data signal to other devices can be reduced; in addition, by increasing the transmit power of a reference signal and retransmitting the reference signal and the data signal, the transmission reliability of the reference signal and the data signal can be improved.
