A communication system (100) is facilitated by an access node (102) to support communication with subscriber units (104, 106) as secondary users of a regulated spectrum portion. The access node requests permission to operate as a secondary user from an authorization server (118). The authorization server provides authorized transmission parameters based on characteristics of the access node. The access node operates according to the authorized transmission parameters and provides the parameters to eligible subscriber units.
