<p>When a device is contending for the right to transmit on a wide channel (composed of a primary narrow channel and one or more secondary narrow channels), it may halt its backoff counter if one of the secondary channels is detected as busy, and restart the backoff counter from its halted value when all the channels are again detected as idle. Some embodiments may use a guard interval detection technique to aid in sensing whether the secondary channels are busy.</p> |
