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.
