Frequency spectrum aggregation resource distributing method based on cognitive radio technology

The invention discloses a frequency spectrum aggregation resource distributing method based on the cognitive radio technology, relates to a frequency spectrum aggregation resource distributing method, and aims to solve the problem that the cognitive frequency spectrum resource cannot be effectively distributed under the condition of the cognitive radio technology of the existing frequency spectrum aggregation algorithm. The method comprises the following steps: 1, obtaining information and equivalent throughput of cognitive frequency spectrum authorization users by using a frequency spectrum perception algorithm; 2, selecting a corresponding cognitive frequency spectrum as a component carrier of the frequency spectrum aggregation and ensuring that the total throughput of the aggregation component carrier meets the requirements of frequency spectrum aggregation users; 3, ranking user data to be transmitted from high to low according to priority and ensuring the user data transmission fairness; 4, distributing the user data to the corresponding component carrier in two cases according to the priority order of the user data. The frequency spectrum aggregation resource distributing method is suitable for distribution of frequency spectrum aggregation resources.
