1. A method, comprising:
detecting, by a processor of an apparatus, 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 the processor 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, by the processor, a transmission at least on the first non-primary channel during the TXOP,
wherein the obtaining of the TXOP comprises:
initiating the TXOP on the first non-primary channel responsive to the backoff counter counting down to zero on the first non-primary channel; and
determining a bandwidth of the TXOP according to a medium status of each of the at least one non-primary channel other than the first non-primary channel during a specific time interval before a start of the TXOP.
