Abstract: Systems, methods, apparatuses, and computer program products for an interleaved multi-beam acquisition waveform providing concurrent beam selection, automatic gain control (AGC) and automatic frequency correction (AFC) are provided. The access point (AP) may send an acquisition waveform on multiple beams, then return and retransmit an AFC on the multiple beams thus interleaving beam switching with the acquisition and frequency correction waveforms. AGC correction can be deferred until the end, relying on the fact that the transmitter may be detected at close range using a one of the multi-beams that is attenuated.
