A method of dynamically allocating RF communication channels to a wireless communication device (102). A plu-rality 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 se-lected 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).

L'invention concerne un procédé qui consiste à attribuer de manière dynamique des canaux de communication RF à un dispositif de communication sans fil (102). Une pluralité de canaux d'allocation dynamique de spectre (canaux DSA) (222, 224) peut être identifiée. Ces canaux DSA peuvent être des canaux disponibles pour un utilisateur non titulaire afin de servir aux communications RF. Sur la base d'un ou plusieurs paramètres de canal requis, un canal DSA peut être sélectionné en tant que premier canal à attribuer au dispositif de communication sans fil. Il est possible de sélectionner au minimum un second canal à attribuer au dispositif de communication sans fil, sur la base d'une relation spectrale entre le premier et le second canal, afin de garantir que le premier et le second canal sont séparés au moins par un espacement des fréquences minimal requis (216).
