1. A method for wireless communication at a user equipment (UE), comprising:
receiving radio resource control (RRC) signaling, the RRC signaling including an indication of two or more available uplink channel transmission occasions for random access message transmission, wherein the two or more available uplink channel transmission occasions span at least two slots;
selecting at least one uplink channel transmission occasion of the two or more available uplink channel transmission occasions for transmission of a random access message;
formatting the random access message, based at least in part on the RRC signaling and the selected at least one uplink channel transmission occasion, to include a preamble, a reference signal, and a physical uplink shared channel (PUSCH), wherein reference signal resources for the reference signal include at least one symbol in a of the PUSCH; and
transmitting the random access message using the selected at least one uplink channel transmission occasion.
