Claim 14:
15. An apparatus, comprising:
a transceiver configured to communicate wirelessly; and
a processor coupled to the transceiver and configured to perform, via the transceiver, operations comprising:
detecting a primary channel busy, with the primary channel being a part of an operating bandwidth having a plurality of channel segments comprising the primary channel and at least one non-primary channel;
obtaining, by using a backoff counter, a transmission opportunity (TXOP) through a first non-primary channel of the at least one non-primary channel responsive to the detecting; and
performing a transmission at least on the first non-primary channel during the TXOP,

wherein the obtaining of the TXOP comprises:
resuming a suspended backoff procedure or initiating a new backoff procedure such that the backoff counter counts down on the first non-primary channel; and
initiating the TXOP on the first non-primary channel responsive to the backoff counter counting down to zero on the first non-primary channel.
