    Abstract: One aspect disclosed is a method in a wireless communications system including a first primary channel having a first frequency spectrum bandwidth and a second primary channel having a second frequency spectrum bandwidth, wherein the second frequency spectrum bandwidth includes the first frequency spectrum bandwidth. The method includes performing a first and a second back-off procedure at least partially in parallel, the first back-off procedure based on whether the first primary channel is idle, and the second back-off procedure based on whether the second primary channel is idle, and transmitting a wireless message based on whether the first or the second back-off procedure completes first.

    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for managing wireless local area network (WLAN) density. The WLAN density is managed to limit how many APs can utilize a first portion of a first frequency band in a geographical area. A limit of APs may be based on an estimated amount of interference that would be caused by the APs to an incumbent system that also uses the first portion of the frequency band. The WLAN density control may prevent the estimated amount of interference caused by APs in a geographical area from exceeding a threshold interference level based on the presence of the incumbent system. WLAN density control may involve the AP configuration of a first AP or may involve the density of client devices associated with one or more APs in the geographical area.

    Abstract: Methods and systems disclosed provide for clear channel assessment of first and second communication channels. In one aspect, a first primary channel has a first frequency spectrum bandwidth and a second primary channel has a second frequency spectrum bandwidth including the first frequency spectrum bandwidth. A method may include performing a first back-off procedure based on whether the first primary channel is idle if a transmission bandwidth for a wireless message is the first frequency spectrum bandwidth, performing a second back-off procedure based on whether the second primary channel is idle if the transmission bandwidth for the wireless message is greater than the first frequency spectrum bandwidth, and transmitting the wireless message based on a completion of the performed back off procedure.

    Abstract: A method and system for obtaining an available white space channel for wireless communication using a white space device (WSD) are described. The WSD scans signals of TV transmitters, determines the received signal strength (RSSI) for those signals, and records TV data, including TV designations and corresponding RSSIs, for signals that exceed a predetermined threshold. The WSD sends TV data for at least three TV transmitters to an enhanced TV white space database (EnTVDB). The EnTVDB uses the TV data and information in its database to determine the geo-coordinates of the WSD. The EnTVDB uses the geo-coordinates of the WSD to identify available white space. The EnTVDB sends at least one channel of available white space to the white space device for its wireless communication.
