1. An apparatus for wireless communications at a user equipment (UE), comprising:
one or more memories; and
one or more processors coupled with the one or more memories and configured to cause the apparatus to:
receive a message indicating a configuration for repeating transmissions of a first random access message of a random access procedure;
select a set of random access occasions for a quantity of repetitions of the first random access message in accordance with the configuration and a mapping rule, wherein:
the set of random access occasions is based at least in part on an association between the set of random access occasions and one or more synchronization signal blocks,
the mapping rule is based at least in part on resources associated with each random access occasion of the set of random access occasions,
a first valid random access occasion of the set of random access occasions is determined in accordance with the mapping rule comprising an ordering of valid random access occasions within a time period, the ordering comprising first, in increasing order of frequency resource index for frequency multiplexed random access occasions, and second, in increasing order of a time resource index for time multiplexed random access occasions, and
respective random access occasions of the set of random access occasions are non-overlapping in time; and
transmit the quantity of repetitions of the first random access message using a same spatial filter via the set of random access occasions.
