An embodiment of the invention provides a dynamic frequency spectrum sharing method and apparatus and relates to the technical field of communication, and the dynamic frequency spectrum sharing method and apparatus can help improve flexibility of frequency spectrum sharing. The method comprises the following steps: Q values for one period are added in a Q value list via a base station, actions of a maximum Q value in the period is reported to a base station management device via the base station, the base station receives a frequency spectrum distribution message sent by the base station management device, and the frequency spectrum distribution message comprises frequency spectra distributed for the base station for a next period via the base station management device. The Q values for the period represent estimated overall return obtained via different actions taken in network states of the period, the network states represent frequency spectrum income for unit time and unit bandwidth in different cells of multiple network types, the different cells of multiple network types are managed via the base station management device of the base station, and the actions are used for representing the quantity of information channels that can be applied by the base station. The dynamic frequency spectrum sharing method and apparatus disclosed in the embodiment of the invention can be applied to dynamic frequency spectrum sharing.
Description
technical field [0001] The present invention relates to the field of communication technologies, in particular to a dynamic spectrum sharing method and device. Background technique [0002] Wireless spectrum is a limited resource with economic and social value. At present, the main spectrum allocation method is to allocate a fixed frequency band for each network. For example, the uplink frequency band of China Unicom 2G network is 909MHZ-915MHZ, while the uplink frequency band of China Unicom 3G network is 1940MHZ-1955MHZ . With this allocation method, when there is a certain number of idle frequency bands in a certain network, other networks cannot use the idle frequency bands and can only use the frequency bands allocated to themselves, resulting in a waste of spectrum resources. [0003] In order to improve spectrum utilization, a spectrum sharing scheme is proposed in the prior art, specifically: according to the spectrum utilization of different networks (that is, cell...
