Abstract:
A Cognitive Radio (CR) communication apparatus is provided. The CR communication apparatus may include a determination unit to determine any one of a plurality of Radio Access Technologies (RATs) as a temporary control RAT, an estimation unit to estimate an available resource and a channel state of each common RAT using the temporary control RAT, and a selection unit to calculate an available capacity of each of the common RATs using the available resource and the channel state, and to select an optimum RAT from the common RATs based on the available capacity of each of the common RATs. The common RATs may be used by the CR communication apparatus and a receiving CR communication apparatus from among the plurality of RATs.
