Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration of random access resources from a base station. The configuration may indicate a quantity of a plurality of random access preambles, a quantity of a plurality of synchronization signal blocks (SSBs), and a quantity of random access preambles per SSB. The received configuration may indicate that each random access preamble of the plurality of random access preambles is available to the UE in the random access occasion for each SSB of a plurality of SSBs transmitted by the base station. The UE may select a random access preamble of the plurality of random access preambles based at least in part on the received configuration and transmit the selected random access preamble to the base station in the random access occasion.
