Abstract

The embodiment of the invention provides a PTRS mapping method and communication equipment. The method comprises the steps of acquiring a PTRS ; Mapping the PTRS to a subcarrier where at least one REin an OFDM symbol of a micro time slot is located with the time domain density of 1 / dt, wherein the subcarrier is a subcarrier where a DMRS is located, the at least one RE is an RB unoccupied by CORESET, the dt is a step length larger than or equal to 1, and the dt is smaller than the number of OFDM symbols included in the micro time slot. The channel estimation performance and the phase noise estimation performance based on micro time slot transmission can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a phase tracking reference signal (PhaseTracking Reference Signal, PTRS) mapping method and a communication device. Background technique [0002] Fifth generation (5 th generation, 5G) communication system uses high frequency band communication to increase link transmission rate. However, in practical applications, usually the higher the operating frequency, the greater the phase noise. Therefore, for high-frequency transmission, in order to remove phase noise, the transmitter needs to send a reference signal known to the receiver, that is, PTRS, based on which the receiver can estimate the phase noise and perform corresponding phase compensation. In addition, in order to better support low-latency services in the 5G communication system, the 5G communication system also supports transmission based on mini-slots, where a mini-slot can includ...
