Dynamic spectrum allocation (DSA) in a communication network
First Claim
1. 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 for preventing crosstalk.

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).
