1. A base station for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
generate a signal using a frequency domain beam sweeping technique that is based at least in part on a set of beamforming weights and a set of time delays; and
transmit, via a transceiver, a first portion of the signal over a first sub-band in a first spatial direction and a second portion of the signal over a second sub-band in a second spatial direction, wherein:
the first portion of the signal and the second portion of the signal are transmitted at a same time,
the first portion of the signal comprises a first synchronization signal block (SSB),
the second portion of the signal comprises a second SSB,
the first SSB is associated with a first sub-band index of the first sub-band,
the second SSB is associated with a second sub-band index of the second sub-band,
the first SSB and the second SSB comprise a set of SSBs,
the first sub-band and the second sub-band comprise a first set of sub-bands, and
the first spatial direction and the second spatial direction comprise a first set of spatial directions.
