Abstract
A method for phase tracking reference signal (PT-RS) signals transmission includes receiving, by a user equipment (UE) from a base station (BS), one or more messages comprising uplink PT-RS configuration parameters and transmitting, by the UE to the BS, PT-RS signals via radio resources of a physical uplink shared channel (PUSCH). The transmitting is based on: the uplink PT-RS configuration parameters, a PT-RS sequence generation process for generating a PT-RS sequence, wherein the PT-RS sequence is based, on a, chirp signal with a time-varying frequency according to a chirp factor and an PT-RS mapping process for mapping the generated PT-RS sequence to the radio resources of the PUSCH.
