1. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to cause the UE to:
receive an indication of a repetition factor associated with a data message or an indication that demodulation reference signal (DMRS) bundling is to be applied for the data message for joint channel estimation; and
communicate a phase tracking reference signal (PTRS) associated with the data message based at least in part on receiving the indication of the repetition factor or the indication that DMRS bundling is to be applied.
