802.22 vs Cognitive WiMAX

802.22 is planning on using an OFDM structure similar to 802.16. 802.22 is being designed specifically as a cognitive technology due to the requirement of coexistence between units and the need to not interfere with incumbents (television, wireless microphones)

Besides the frequency being used, what would the difference be between a fully cognitive 802.16 and 802.22. I guess the requirement to not defer to an incumbent
