1. A base station for wireless communication, comprising:
a memory;
a transceiver; and
one or more processors, coupled to the memory and the transceiver, configured to:
generate a signal for a set of synchronization signal blocks (SSBs) for an SSB burst set, wherein the set of SSBs are associated with a set of analog beamforming configurations associated with a set of spatial directions;
transmit, via the transceiver, the signal for the set of SSBs using the set of analog beamforming configurations over the set of spatial directions; and
receive, via the transceiver and using a true-time-delay architecture to use a set of frequency domain beam sweeping configurations corresponding to the set of analog beamforming configurations, a plurality of random access channel (RACH) communications from a plurality of spatial directions, the plurality of RACH communications corresponding to a plurality of SSBs of the set of SSBs.
