1. A method, comprising:
announcing, to one or more stations (STAs), in a frame one or more preamble detection (PD) channels in a frequency segment such that each of the one or more STAs monitors a respective one of the one or more PD channels to detect any transmission on the one or more PD channels; and
wirelessly communicating with at least one of the one or more STAs on one of the one or more PD channels during a transmission opportunity (TXOP),
wherein the wirelessly communicating with the at least one of the one or more STAs comprises at least one of:
performing a downlink (DL) transmission to the at least one of the one or more STAs after the at least one of the one or more STAs switching to a different PD channel in a same or a different frequency segment; and
triggering an uplink (UL) transmission from the at least one of the one or more STAs after the at least one of the one or more STAs switching to the different PD channel in the same or the different frequency segment.
