Coexistence of multiple radio systems in unlicensed bands
First Claim
1. A method of operating a first transceiver in a wireless communication environment capable of including one or more other transceivers, wherein the first transceiver sends and receives traffic in accordance with a first communications standard, and one or more of the one or more other transceivers send and receive traffic in accordance with one or more other communication standards that are incompatible with the first communications standard such that traffic sent in accordance with any of the first and other communications standards cannot be received by a receiver operating in accordance with any other one of the first and other communications standards, the method comprising:
- identifying a carrier frequency for use as a shared broadcast channel that is accessible by the first transceiver and by the one or more other transceivers; and
broadcasting information on the shared broadcast channel, wherein the information informs the one or more other transceivers of the presence of the first transceiver,wherein broadcasting the information on the shared broadcast channel comprises;
approximating a signaling format that is used or approximated by all of the first and other transceivers to broadcast information on and receive information from the shared broadcast channel.

Abstract
A transceiver operates in a communication environment capable of including other transceivers, wherein the transceiver sends and receives traffic in accordance with a first communications standard, and other transceivers send and receive traffic in accordance with other communication standards that are incompatible with the first communications standard such that traffic sent in accordance with any of the first and other communications standards cannot be received by a receiver operating in accordance with any other one of the first and other communications standards. The transceiver identifies a carrier frequency for use as a shared broadcast channel that is accessible by the transceiver and by the other transceivers, and broadcasts information on the shared broadcast channel, wherein the information informs the other transceivers of the presence of the transceiver. The transceiver also receives information from the shared broadcast channel, wherein the information informs the transceiver of the presence of the other transceivers.
