1. A method for communicating via a plurality of channel segments that includes i) a first channel segment in a first radio frequency (RF) band, and ii) a second channel segment in a second RF band, the method comprising:
maintaining, at a communication device, a first backoff counter that corresponds to the first channel segment, the first backoff counter for determining when the communication device can transmit via the first channel segment;
maintaining, at the communication device, a second backoff counter that corresponds to the second channel segment, the second backoff counter for determining when the communication device can transmit via the second channel segment;
determining, at the communication device, whether the communication device is permitted to transmit via the first channel segment simultaneously with receiving via the second channel segment;
in response to determining that the communication device is not permitted to transmit via the first channel segment simultaneously with receiving via the second channel segment, suspending the second backoff counter when transmitting via the first channel segment; and
in response to determining that the communication device is permitted to transmit via the first channel segment simultaneously with receiving via the second channel segment, counting the second backoff counter while transmitting via the first channel segment.
