1. A method of wireless communication at a user equipment (UE) device, comprising:
reporting first capabilities supporting demodulation reference signal (DMRS) sharing for a first repetition type and second capabilities supporting DMRS sharing for a second repetition type;
receiving control information that indicates mapping of uplink transmission parameters to a plurality of DMRS sharing patterns;
prior to transmitting an uplink transmission, identifying that the uplink transmission is associated with one or more parameters of the uplink transmission parameters, the one or more parameters including one of the first repetition type or the second repetition type;
identifying a DMRS sharing pattern from among the plurality of DMRS sharing patterns by using the one or more parameters as a lookup to the plurality of DMRS sharing patterns;
selecting the DMRS sharing pattern for the uplink transmission in accordance with identification of the DMRS sharing pattern; and
transmitting, to a base station, the uplink transmission in accordance with the DMRS sharing pattern.
