Abstract: An apparatus receives a configuration for a phase tracking reference signal (PT-RS). The apparatus then determines at least one of a time density or a frequency density for the PT-RS based on inter-slot repetition of a transmission. The apparatus then receives or transmits the PT-RS based on the at least one of the time density or the frequency density determined based on the inter-slot repetition of the transmission.
