Abstract: A reference signal sending method and a communications device are provided. The reference signal sending method includes: generating, by a first device, a tracking reference signal, where the tracking reference signal corresponds to a DMRS port that is used by the first device when the first device sends data to a second device; mapping, by the first device, the tracking reference signal to a time-frequency resource that is used by the first device when the first device sends the data to the second device through the DMRS port, where the tracking reference signal is mapped to at least two modulation symbols on a same frequency resource in one transmission slot; and sending, by the first device, the tracking reference signal mapped to the time-frequency resource to the second device.

Abstract: Embodiments of the present disclosure provide systems, methods and apparatus for reference signal configuration. The method includes: mapping a phase tracking reference signal (PTRS) to one or more OFDM symbols based on information about a correspondence between the PTRS and one or more of a modulation and coding scheme (MCS), a subcarrier spacing, and a bandwidth (BW); and sending the one or more OFDM symbols to which the PTRS is mapped to a receive device. In the embodiments of the present invention, a correspondence between the PTRS and the subcarrier spacing or the modulation and coding scheme or the bandwidth is used to implicitly indicate a time-frequency location of the PTRS. In comparison with the prior art, no explicit indication is required, and signaling overheads are reduced.
