1. A method for wireless communication at a user equipment (UE), comprising:
receiving, from a network device, a control message comprising an indication of a reference signal configuration associated with one or more physical channels scheduled during a plurality of time slots;
determining, based at least in part on the control message and an absence of a demodulation reference signal in a first time slot of the plurality of time slots, a location for transmitting a phase tracking reference signal in the first time slot, the first time slot comprising a plurality of resource elements; and
transmitting, to the network device, the phase tracking reference signal in the first time slot at the determined location.
