Document Type and Number:

WIPO Patent Application WO/2018/228522

Kind Code:

A1

Abstract:

The present application provides a reference signal sending method. The method comprises: determining a resource set, which is used for bearing a demodulation reference signal and downlink information, the downlink information being downlink control information or downlink data, the demodulation reference signal being used for demodulating the downlink information, the resource set comprising a first time frequency resource set and a second time frequency resource set, the first time frequency resource set being a reserved time frequency resource set, and the second time frequency resource set being used for bearing the demodulation reference signal; determining a third time frequency resource set according to the position of the second time frequency resource set and a preset offset when there is an overlapping portion between the first time frequency resource set and the second time frequency resource set; and sending the demodulation reference signal according to the third time frequency resource set. Therefore, transmission of a demodulation reference signal can be reliably implemented, and thus the reliability of communication is improved.
