1. A method for wireless communication, comprising:
receiving a configuration indicating multiple association rules associating random access preambles and physical uplink shared channel (PUSCH) occasion formats, wherein each PUSCH occasion format of the PUSCH occasion formats is based on a corresponding one of multiple configured subcarrier spacings;
selecting, as part of a random access procedure, a random access preamble from the random access preambles for transmitting over a random access occasion;
determining, based at least in part on at least one of the multiple association rules indicated by the configuration, a PUSCH occasion format associated with the random access preamble and a corresponding payload resource unit; and
transmitting the random access preamble over the random access occasion and, according to the PUSCH occasion format, an associated payload over the corresponding payload resource unit.
