Channel availability for white-space devices, associated apparatus and methods
First Claim
1. An apparatus comprising a processor and memory, the memory including computer program code, wherein the memory and computer program code are configured to, with the processor, cause the apparatus to:
- receive geographic location signalling associated with particular determined geographical locations of two or more white-space devices of a network;
receive uncertainty indication signalling for respective uncertainties associated with the particular determined geographic locations of the two or more white-space devices, the uncertainty indication signalling indicative of respective uncertainty areas within which the two or more white-space devices may be respectively located according to errors associated with the way in which the particular determined geographical locations of the two or more white-space devices are determined;
determine one or more channels available for use in communication by the respective two or more white-space devices in their particular determined geographical locations based on common channels available for use within the respective uncertainty areas associated with each of the white-space devices and the channels available for use within a defined geometric area over which the network intends to operate by using the geographic location signalling, the uncertainty indication signalling, and channel availability data configured to indicate one or more channels available for communication within a geographic region; and
when a pair of white-space devices in the network have no common channels available for use for communication, identify an indirect communication path between the pair of white-space devices using channels available for use between other white-space devices of the network and each of the white-space devices of the pair.

Abstract
An apparatus configured to determine one or more channels available for use by respective one or more white-space devices in a particular determined geographical location. The apparatus is configured to: receive geographic location signalling associated with the particular determined geographical location of one or more white-space devices; receive uncertainty indication signalling for the uncertainty associated with the particular determined geographic location of the one or more white-space devices; and determine the one or more channels available for use by the respective one or more white-space devices in the particular determined geographical location by using the geographic location signalling and uncertainty indication signalling.

8. A method, the method comprising:
-
receiving geographic location signalling associated with particular determined geographical locations of two or more white-space devices of a network; receiving uncertainty indication signalling for respective uncertainties associated with the particular determined geographic locations of the two or more white-space devices, the uncertainty indication signalling indicative of respective uncertainty areas within which the two or more white-space devices may be respectively located according to errors associated with the way in which the particular determined geographical locations of the two or more white-space devices are determined; receiving channel availability data, the channel availability data configured to indicate one or more channels available for communication within a geographic region; determining one or more channels available for communication by the respective two or more white-space devices in their particular determined geographical locations based on common channels available for use within the respective uncertainty areas associated with each of the white-space devices and the channels available for use within a defined geometric area over which the network intends to operate by using the geographic location signalling, the uncertainty indication signalling, and the channel availability data; and when a pair of white-space devices in the network that have no common channels available for use for communication is identified, identifying an indirect communication path between the pair of white-space devices using channels available for use between other white-space devices of the network and each of the white-space devices of the pair. - View Dependent Claims (9)
