Abstract
A method of dynamically allocating RF communication channels to a wireless communication device (102). A plurality of dynamic spectrum allocation (DSA) channels (222, 224) can be identified. The DSA channels can be channels that are available to a non-incumbent user to be used for RF communications. Based on at least one required channel parameter, a DSA channel can be selected as a first channel to allocate to the wireless communication device. At least a second channel can be selected to allocate to the wireless communication device based on a spectral relationship between the first channel and the second channel to ensure that the first and second channels are separated by at least a minimum required frequency separation (216).
Claims22
A method of dynamically allocating RF communication channels to a wireless communication device, comprising:
- identifying a plurality of dynamic spectrum allocation (DSA) channels that are available to a non-incumbent user to be used for RF communications;
- based on at least one required channel parameter, selecting at least one of the DSA channels as a first channel to allocate to the wireless communication device;
- and
- selecting at least a second channel to allocate to the wireless communication device based on a spectral relationship between the first channel and the second channel to ensure that the first and second channels are separated by at least a minimum required frequency separation.
A method of dynamically communicating over a plurality of RF communication channels, comprising:
- receiving a list of a plurality of DSA channels that are available to a non-incumbent user to be used for RF communications;
- scanning the plurality of the DSA channels to generate scan results that indicate which of the plurality of DSA channels are presently unoccupied;
- communicating the scan results to a cognitive radio controller that implements cognitive channel allocation;
- and
- receiving an allocation of at least one of the DSA channels to be used as a first channel for RF communications, the DSA channel being selected based, at least in part, on the scan results and the DSA channel being separated from at least a second channel by at least a minimum required frequency separation.
A dynamic spectrum allocation (DSA) communication system, comprising:
- a cognitive radio controller that:
- identifies a plurality of DSA channels that are available to a non-incumbent user to be used for RF communications;
- based on at least one required channel parameter, selects at least one of the DSA channels as a first channel to allocate to the wireless communication device;
- and
- selects at least a second channel to allocate to a wireless communication device based on a spectral relationship between the first channel and the second channel to ensure that the first and second channels are separated by at least a minimum required frequency separation.
