Techniques for transmitting phase tracking reference signals in resources associated with uplink channel repetitions

A method of wireless communication performed by a network node, comprising:

• receiving, from a user equipment (UE), phase tracking reference signals (PTRSs) in resources within uplink channel repetitions based at least in part on one or more of:
• a resource allocation associated with the uplink channel repetitions, or
• a channel usage indicating whether:
• a downlink reception is present in resources in time between the uplink channel repetitions, or another uplink transmission is present in the resources in time between the uplink channel repetitions;
• and
• transmitting, to the UE, demodulation reference signal bundles across one or more slots based at least in part on the PTRSs, wherein the PTRSs are associated with a time density and a frequency density.

A user equipment (UE) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• determine one or more of:
• a resource allocation associated with uplink channel repetitions, or
• a channel usage indicating whether:
• a downlink reception is present in resources in time between the uplink channel repetitions, or another uplink transmission is present in the resources in time between the uplink channel repetitions;
• and
• transmit, to a network node, phase tracking reference signals (PTRSs) using resources within the uplink channel repetitions based at least in part on the determination of the one or more of the resource allocation or the channel usage, wherein the PTRSs are associated with a time density and a frequency density.
