Abstract: The present disclosure provides a method and apparatus for reference signal configuration. The method includes: determining a time domain density of a phase tracking reference signal (PTRS) according to a first modulation and coding scheme (MCS) and correspondence information between MCSs and PTRS time domain densities; determining a frequency domain density of the PTRS according to a first scheduled bandwidth and correspondence information between scheduled bandwidths and PTRS frequency domain densities; and mapping the PTRS to one or more resource elements (REs) according to the time domain density of the PTRS and the frequency domain density of the PTRS when certain conditions are met.

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 Demodulation Reference Signal (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: The present invention provides a multi-channel array distortion compensation apparatus and method. The apparatus determines, according to a status of a first indication signal, whether to trigger a signal compensation operation; determines, according to a status of a second indication signal, a first adjustment condition is met, compares power of a received signal with a power threshold, and if the power of the received signal is greater than the threshold power, compensates the received signal according to a first adjustment factor; and if the status of the second indication signal does not meet the first adjustment condition, determines the status of the second indication signal meets a second adjustment condition, performs auxiliary compensation according to a second adjustment factor. By compensating signal distortion caused by chip stacking for a received signal, this reduces costs for implementing a multi-channel array system without the need to increase system complexity.
