Abstract:
1. A carrier aggregation apparatus, comprising: a level assignment manager configured to perform management by classifying a license band allocated to a cognitive radio cell into a primary radio resource (PRR) level, and by classifying a shareable band obtained through a cognitive radio database or spectrum sensing into an auxiliary radio resource (ARR) level; a determiner configured to determine a quality of service (QoS) level of a communication service provided to the cognitive radio cell; and a service provider configured to allocate a frequency resource of the PRR level when the QoS level requires a first communication service, and to allocate a frequency resource of the ARR level when the QoS level requires a second communication service lower than the first communication service, wherein the service provider, based upon a priority required by a user, is configured to alternatively provide the second communication service using the frequency resource of the PRR level and to provide the first communication service using the frequency resource of the ARR level.
