Support for demodulation reference signal bundling by a base station

An apparatus for wireless communication at a user equipment (UE), comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• perform one or more procedures that support demodulation reference signal (DMRS) bundling;
• and
• transmit, within a set of multiple communications comprising repetitions of a random access channel message, an indication that indicates performance of the one or more procedures that support the DMRS bundling for the set of the multiple communications.

An apparatus for wireless communication at a network node, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• receive, via a transmission channel, a set of multiple communications, wherein the set of the multiple communications comprises repetitions of a random access channel message;
• and
• apply demodulation reference signal (DMRS) bundling across the set of the multiple communications based at least in part on an indication received from a user equipment (UE).
