System and method utilizing a cognitive transceiver for ad hoc networking
First Claim
1. A method comprising:
- determining, at a first wireless station, an idle broadcast channel from a plurality of broadcast channels based on indicators of channel status information for the plurality of broadcast channels, the indicators of the channel status information identifying one or more channels of the plurality of broadcast channels as idle channels;
initiating a connection on the idle broadcast channel between the first wireless station and a second wireless station; and
subsequent to the connection being established, transmitting first data over the idle broadcast channel.

Abstract
The present invention provides methods and apparatuses for utilizing unused portions of an allocated frequency spectrum in a wireless communications system that broadcasts content to wireless stations. A first wireless station may communicate with a second wireless station on an idle broadcast channel while keeping the resulting interference level below an acceptable maximum limit at the other wireless stations. Using interference level information that are measured at the wireless stations, the wireless station can negotiate with the other wireless station on an establishment channel for subsequent communications on one or more broadcast channels. The wireless station may receive broadcast content on a time slice that corresponds to a broadcast channel and that is further processed by the wireless station. Otherwise, the wireless station can utilize the corresponding time to measure an interference level for the corresponding channel or to transmit or receive data to/from another wireless station.
