Claim Text:
1. A method of operating a network station, the method comprising: determining a framing of a cooperative network transmission on a first frequency; scheduling an asynchronous detection interval within a frame defined by the identified framing of the cooperative network; detecting for non-cooperative transmissions on the first frequency during the asynchronous detection interval, the non-cooperative transmissions originating from a source not participating in the cooperative network; detecting for non-cooperative transmissions on a second frequency; determining that the first frequency is occupied based upon a presence of a non-cooperative transmission detected on the first frequency; determining that the second frequency is not occupied based upon an absence of non-cooperative transmissions detected on the second frequency; tuning a receiver to the second frequency responsive to information regarding occupancy of the first and second frequencies; and receiving a transmission from a cooperative network station on the second frequency.
