1. A method for wireless communications, comprising:
configuring, at a base station, a first set of synchronization signal block (SSB) beams from a plurality of SSB beams with a first set of random access channel (RACH) occasion density, wherein the RACH occasion density identifies time and frequency resources that one or more user equipments (UEs) can utilize to transmit initial access requests to the base station;
configuring a second set of SSB beams from the plurality of SSB beams with a second set of RACH occasion density, wherein the first set of RACH occasion density is greater than the second set of RACH occasion density for the second set of SSB beams; and
transmitting a system information message to the one or more UEs that includes a beam-specific bit-field to indicate the first set of RACH occasion density for the first set of SSB beams and the second set of RACH occasion density for the second set of SSB beams.
