at least one processor coupled to the memory and configured to:
transmit, to a network entity, a first indication of a maximum demodulation reference signal (DMRS) bundling duration for maintaining transmit phase coherence for transmitted DMRS;
receive, from the network entity, a second indication of at least one of a DMRS bundling activation or a DMRS bundling duration; and
transmit at least one uplink (UL) repetition including bundled DMRS based on the at least one of the DMRS bundling activation or the DMRS bundling duration.
