1. An apparatus for wireless communication at a first user equipment (UE), comprising:
memory; and
at least one processor coupled to the memory, the memory and the at least one processor configured to:
receive a first sidelink transmission including at least a first demodulation reference signal (DMRS);
receive a second sidelink transmission, the first sidelink transmission and the second sidelink transmission together including at least the first DMRS and a second DMRS;
receive, from a second UE, an indication of a bundling relationship between the first sidelink transmission and the second sidelink transmission, the bundling relationship including at least one of strong bundling, weak bundling, or no bundling; and
perform channel estimation for a channel associated with the first sidelink transmission and the second sidelink transmission based at least in part on the bundling relationship.
