1. A method for wireless communications by a user equipment (UE), comprising:
receiving, from a network entity, signaling that triggers the UE to transmit additional demodulation reference signal (A-DMRS) for at least one physical uplink shared channel (PUSCH), relative to DMRS indicated in a current PUSCH DMRS configuration; and
transmitting the at least one PUSCH including the A-DMRS, wherein the A-DMRS is triggered only when a number of resource blocks (RBs) allocated for the at least one PUSCH is at or below a threshold value.
