Cognitive Layer

• Cognitive layer inclusion in Whitespace radio spec• Whitespace and Geo-db operation related primitives• Channel/Spectra availability and permission related constructs

– AVAIL_SPECTRUM_REQ Message from Slave to Master

• Primary/Secondary user identification for Busy channels• Channel scan and Beacon scan based on the available spectra

at a given location/time• Support primitives in MAC and PHY layer

– Fair MAC, DCR MAC, etc.

• Device capability and permissions– Ruleset, antenna, power levels, mobility, and location

Cognitive Coexistence

• Self Coexistence of Radios– Both in License and Unlicensed bands

• Hybrid mechanisms; autonomous + centralized• Dynamic opportunistic spectrum sharing between networks• Home network, Foreign network identification for idle and

busy channels/spectra• Intelligent adaptive manipulation of interference and

opportunistic access• Interference prediction, analytics and learning• Adaptive Multi user detection schemes• Parallel simultaneous transmissions
