Abstract: An apparatus is configured to be employed within a base station. The apparatus comprises baseband circuitry which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured to arrange phase tracking reference signal (PT-RS) resource elements (REs) and data REs as an arrangement for a transmission based on one or more diversity factors. The one or more diversity factors include a time domain and a frequency domain. The one or more processors are also configured to provide the transmission having the PT-RS REs to the RF interface for transmission to a user equipment (UE) device.
