Abstract: A communication device performs a first backoff operation with a first backoff counter to determine when to transmit a first packet in a first frequency, and performs a second backoff operation with a second backoff counter to determine when to transmit a second packet in a second frequency segment. In connection with the first backoff counter expiring, the communication device transmits the first packet in the first frequency segment. In connection with the second backoff counter expiring, the communication device transmits the second packet in the second frequency segment simultaneously with transmitting the first packet in the first frequency segment. In response to determining that transmission of the first packet in the first frequency segment failed, the communication device increases a first contention window for a retransmission of the first packet, and does not adjust the second contention window for a next transmission in the second frequency segment.
