operating the node to send a request-to-send message including information regarding the weighted queue size;
operating a receiving node that receives the request-to-send message to send a clear-to-send message in reply, with the clear-to-send message comprising information pertaining to a weighted queue size for a transmit queue of the receiving node; and
operating a receiving node that receives the request-to-send message to send a not-clear-to-send message in reply, with the not clear-to-send message comprising information pertaining to the weighted queue size for the transmit queue of the receiving node.
