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.

Abstract: The present invention relates to the field of mobile communications technologies, and in particular, to a signal transmission method, and an apparatus. In this solution, a technical feature of sending, to a receive end, an alternative transmission configuration corresponding to a selected first CQI is used. In this technical feature, the alternative transmission configuration sent to the receive end is an alternative transmission configuration corresponding to the selected first CQI. The technical feature can overcome disadvantages of relatively low accuracy of a signal obtained through demodulation by the receive end and relatively high feedback overheads in a signal transmission process. Therefore, the present invention can overcome the disadvantages of relatively low accuracy of a signal obtained through demodulation by the receive end and relatively high feedback overheads in the signal transmission process.
