20120320897	SYSTEM AND METHOD FOR DATA DISTRIBUTION IN VHF/UHF BANDS - Whitespace devices can use unused television frequencies for transmission and reception of WiFi OFDM signals. Three contiguous bands, such as former channels 2, 3, and 4, may be bonded together to define a whitespace band. In order to fit a WiFi OFDM signal into this whitespace band, a whitespace device compresses the bandwidth of each WiFi OFDM signal using a specific spectrum mask. Very low transmission power is needed for the modified WiFi OFDM signals, eliminating the need for high power amplifiers and most of the WiFi OFDM designs such as PHY and MAC can be reused with minor modifications.	12-20-2012
20120320882	INTERCELL INTERFERENCE MITIGATION - Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.	12-20-2012
20120320865	WIRELESS LOCAL AREA NETWORK USING TV WHITE SPACE SPECTRUM AND LONG TERM EVOLUTION SYSTEM ARCHITECTURE - A wireless local area network (WLAN) gateway uses a LTE radio frame and TV white space spectrum for data communications in a wireless local area network. In the LTE downlink frame, a predefined subset of the pilot (reference) symbol positions are used to carry information to data sinks in the WLAN.	12-20-2012
