In one aspect, a first primary channel has a first frequency spectrum bandwidth and a second primary channel has a second frequency spectrum bandwidth including the first frequency spectrum bandwidth. A method may include performing a first back-off procedure based on whether the first primary channel is idle if a transmission bandwidth for a wireless message is the first frequency spectrum bandwidth, performing a second back-off procedure based on whether the second primary channel is idle if the transmission bandwidth for the wireless message is greater than the first frequency spectrum bandwidth, and transmitting the wireless message based on a completion of the performed back off procedure.
