    Abstract: Disclosed are a method and device for determining and assisting in determining a back-up frequency in a cognitive radio system. A first cognitive system shares the wireless communication spectrum resources of an incumbent system, and the method thereof for determining a back-up frequency comprises: through a terminal, a first cognitive system obtaining a back-up frequency of a second cognitive system which has overlapping coverage in a target area in an overlapping coverage area; and according to the back-up frequency of the second cognitive system in the overlapping coverage area, selecting from the wireless communication spectrum resources at least one frequency as a back-up frequency in the target area. When determining the back-up frequency, the first cognitive system can refer to the back-up frequency of the second cognitive system to conduct determination, thereby optimizing the system performance.

    Abstract: Various examples of the present disclosure describe a method for configuring a quiet period in a CR system and a device thereof. The method includes: determining, by a base station, a maximum value of a quiet period parameter of a CR system based on maximum duration of interference which a radio authorization system tolerates and maximum loss of capacity which the CR system tolerates; determining a sensing algorithm based on a detecting performance requirement and the maximum value of the quiet period parameter; determining a value of the quiet period parameter based on the sensing algorithm; and sending the quiet period parameter to a terminal of the CR system. When the examples of the present disclosure are employed, the rationality of the configuration of the quiet period parameter of the CR system is improved and the capacity loss of the CR system is reduced when the interference to the authorization system is reduced.

    Abstract: The present disclosure provides a dynamic spectrum allocation method and a dynamic spectrum allocation device. In the method, a centralized node performs spectrum allocation and transmits a spectrum allocation result to each communication node, so that the communication node operates at a corresponding spectrum resource in accordance with the spectrum allocation result and performs statistics of communication quality measurement information. The centralized node receives the communication quality measurement information reported by the communication node, and determines whether or not it is required to trigger the spectrum re-allocation for the communication node in accordance with the communication quality measurement information about the communication node. When it is required to trigger the spectrum re-allocation, the centralized node re-allocates the spectrum for the communication node.
