Spectrum sharing method and device based on cognitive database and spectrum sensing

Abstract

The present invention provides a frequency spectrum sharing method and device based on cognition database and frequency spectrum perception. The method comprises: a perception system sends a reading request to the cognition database to allow the cognition database to inquire associated information and feed the inquired result back to the cognition system; the perception system performs the frequency spectrum perception to determine a perception frequency range; the frequency spectrum perception decision is performed according to the query result, the channel quality measurement result and the frequency spectrum perception result to determine the perception resource required application; the perception resource application information is sent to the cognition database according to the frequency spectrum decision result to allow the cognition database to determine the access priority of a plurality of perception systems when a plurality of perception systems apply the same frequency spectrum resource at the same time; the perception resource decision is performed according to the perception resource application information of the perception systems and the access priority; and the perception resource authorization information or the rejection information are sent to the perception systems according to the perception resource decision result. The frequency spectrum sharing method and device based on cognition database and frequency spectrum perception can effectively and reliably realize the frequency spectrum sharing and reduce the frequency spectrum resource waste.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a spectrum sharing method and device based on a cognitive database and spectrum sensing. Background technique [0002] With the continuous development of new wireless communication technologies, as well as the vigorous development of the mobile Internet and the Internet of Things industry, the demand for radio spectrum by various radio services has expanded rapidly, and spectrum resources have become increasingly scarce. The traditional management method of fixed allocation of private network frequencies is exclusive. Due to the business characteristics of industry users, this method is likely to cause relatively low utilization of wireless spectrum in the industry private network, spectrum resources are not fully utilized, and there is a certain degree of waste. Spectrum sharing can break the exclusive occupation of spectrum, open up more available spectru...
