Classification: CPC H | IPC H

Claim 7:
8. A method for wireless communication at a base station, comprising:
transmitting, to a user equipment (UE), a configuration of random access resources indicating a quantity of a plurality of random access preambles, a quantity of a plurality of synchronization signal blocks per random access occasion, and a quantity of random access preambles per synchronization signal block, wherein:
the transmitted configuration indicates that each random access preamble of the plurality of random access preambles is available for selection for each synchronization signal block of a plurality of synchronization signal blocks, each synchronization signal block of the plurality of synchronization signal blocks being associated with a respective beam for reception of the synchronization signal block, the respective beam being associated with a direction for random access preamble communications;
transmitting the plurality of synchronization signal blocks;
receiving, from the UE in the random access occasion via one or more of a plurality of narrow receive beams associated with a single uplink beam and indicative of a direction of the UE relative to the base station, a random access preamble of the plurality of random access preambles that is associated with a synchronization signal block, of the plurality of synchronization signal blocks, received by the UE and with each other synchronization signal block of the plurality of synchronization signal blocks transmitted by the base station; and
transmitting, based at least in part on a determination of the direction of the UE relative to the base station, a first random access response message to the UE.
