Claim Text:
1. A method of managing communication on a wireless channel comprising: a first wireless communication device (WCD) detecting, on the wireless channel, a ready-to-send (RTS) message from a second WCD to a third WCD, the RTS message indicating that the second WCD is ready to send data to the third WCD; responsive to detecting on the wireless channel the RTS message from the second WCD to the third WCD, the first WCD configuring itself to avoid transmission on the wireless channel for a first predefined period, wherein the first predefined time period includes, in sequence beginning at an end of the RTS message, (i) a first interframe interval, (ii) a clear-to-send (CTS) interval, (iii) a second interframe interval, and (iv) a confirmation-to-send (CoTS) interval; the first WCD making a determination of whether the first WCD detects during the first predefined period on the wireless channel a further transmission from the second WCD to the third WCD related to transmission of the data wherein the further transmission from the second WCD to the third WCD is transmission of a CoTS message in the CoTS interval confirming that the second WCD received a CTS message from the third WCD and is going to send the data to the third WCD and carrying a list of wireless channels on which the second WCD will be transmitting to the third WCD; and if the determination is affirmative, then the first WCD continuing to avoid transmission on the wireless channel for a second predefined period, but, if the determination is negative, then the first WCD discontinuing the avoiding of transmission on the wireless channel without the avoiding of transmission for the second predefined period, wherein the second predefined period includes, in sequence beginning at an end of the first predefined period, (i) a third interframe interval, (ii) a data transmission interval, (iii) a fourth interframe interval, and (iv) an ACK interval.
