Demodulation reference signal bundling

A method of wireless communication performed by a transmitter, comprising:

• transmitting an indication associated with a plurality of time-domain resources that are associated for purposes of demodulation reference signal (DMRS) bundling of a physical channel,
• wherein the indication includes one or more DMRS bundling parameters for a DMRS configuration associated with a first subset of the plurality of time-domain resources and a second subset of the plurality of time-domain resources,
• wherein at least one of the one or more DMRS bundling parameters indicates at least one of an offset value associated with DMRS transmissions per time-domain resource length or a location associated with a front-loaded DMRS transmission;
• transmitting, based at least in part on a first DMRS pattern, a plurality of first DMRS transmissions in the first subset of time-domain resources;
• and
• transmitting, based at least in part on a second DMRS pattern, one or more second DMRS transmissions in the second subset of time-domain resources, the first DMRS pattern and the second DMRS pattern being different DMRS patterns.

A receiver for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the one or more processors configured to:
• receive an indication associated with a plurality of time-domain resources that are associated for purposes of demodulation reference signal (DMRS) bundling of a physical channel,
• wherein the indication includes one or more DMRS bundling parameters for a DMRS configuration associated with a first subset of the plurality of time-domain resources and a second subset of the plurality of time-domain resources,
• wherein at least one of the one or more DMRS bundling parameters indicates at least one of an offset value associated with DMRS transmissions per time-domain resource length or a location associated with a front-loaded DMRS transmission;
• and
• determine, based at least in part on receiving the one or more DMRS bundling parameters, a first DMRS pattern for the first subset of time-domain resources, and a second DMRS pattern for a second subset of time-domain resources, the first DMRS pattern and the second DMRS pattern being different DMRS patterns.
