Classification: CPC H | IPC H

Claim 16:
17. An apparatus implementable in a station (STA), comprising:
a transceiver configured to wirelessly communicate with an access point (AP); and
a processor coupled to the transceiver and configured to perform operations comprising:
communicating, via the transceiver, between the AP and the STA, which initially monitors an initial preamble detection (PD) channel and an initial signaling (SIG) content channel in a same frequency segment or different frequency segments of a plurality of frequency segments in an operating bandwidth of the AP, with the AP assigning to the STA either or both of a PD channel and a SIG content channel for a transmission opportunity (TXOP), the PD channel and the SIG content channel assigned by the AP being different from the initial PD channel and the initial SIG content channel, respectively; and
performing, via the transceiver, a frame exchange between the AP and the STA during the TXOP such that the STA monitors a preamble on the PD channel and decodes a SIG content on the SIG content channel, wherein:
the PD channel remains on a primary frequency segment of the plurality of frequency segments and the SIG content channel is assigned to a first secondary frequency segment of the plurality of frequency segments within the operating bandwidth of the STA; or
the PD channel is assigned to a second secondary frequency segment of the plurality of frequency segments and the SIG content channel is assigned to a different frequency segment of the plurality of frequency segments within the operating bandwidth of the STA.
