1. An apparatus for wireless communication at a user equipment (UE), comprising:
memory; and
one or more processors coupled to the memory and configured to cause the UE to:
receive a configuration for a phase tracking reference signal (PT-RS);
determine at least one of a time density or a frequency density for the PT-RS based on inter-slot repetition of a transmission; and
receive or transmit 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.
