1. A method of wireless communication at a user equipment (UE), comprising:
receiving, from a base station, an indication to transmit a set of physical uplink shared channels (PUSCHs), each PUSCH of the set of PUSCHs comprising a corresponding demodulation reference signal (DMRS);
receiving, from the base station, for each PUSCH of the set of PUSCHs, a sounding reference signal (SRS) resource indicator (SRI); and
transmitting, to the base station, the set of PUSCHs comprising the corresponding DMRS, the set of PUSCHs having phase continuity, each PUSCH of the set of PUSCHs being transmitted based on a first SRS resource, the SRI for a first PUSCH of the set of PUSCHs indicating the first SRS resource.
