A user equipment (UE) may receive control signaling indicating a time-domain mapping pattern between one or more random access occasions and one or more physical uplink shared channel (PUSCH) occasions. The UE may transmit one or more preambles of a random access message of a random access procedure in the one or more random access occasions in accordance with the time-domain mapping pattern. Additionally, the UE may transmit one or more PUSCHs (e.g., uplink payload transmissions) of the random access message in the one or more PUSCH occasions in accordance with the time-domain mapping pattern. In some examples, the UE may receive a random access response message based on a timing of the preamble and PUSCH transmissions. ## Claims ### Claim 1 A method for wireless communication at a user equipment (UE), comprising: receiving control signaling indicating a time-domain mapping pattern between one or more random access occasions and one or more uplink shared channel occasions for transmission of a random access message of a random access procedure;
