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:
