Abstract

A method of wireless communication includes a next generation Node B (gNB) configuring a user equipment (UE) with radio resource control (RRC) parameters, selecting a pattern of signal allocation and distribution symmetric in time, frequency, and space, the pattern indicating orthogonal frequency division multiplexing (OFDM) symbol tones and subcarrier of a reference signal (RS), transmitting, to the UE, downlink control information (DCI) indicating the selected pattern, and transmitting at least one or more phase tracking reference signal (PT-RS) and demodulation reference signal (DMRS) in accordance with the RRC parameters and selected pattern.
