Abstract

The invention relates to a multi-level dynamic spectrum sharing method based on blockchain technology, which belongs to the technical field of wireless communication. In this method, system users are divided into three categories, each with different levels of spectrum access rights, and GBC and LBC are constructed between users through blockchain technology; combined with the proposed system, in this method, PAL users can Priority access licenses are obtained through auction for spectrum access and data transmission. GAA users can apply for access to spectrum managed by PAL users, effectively realizing safe sharing and dynamic access of spectrum, thereby improving the utilization rate of spectrum resources. The system and method of the present invention realize secure sharing and dynamic access of spectrum based on block chain technology, thereby improving spectrum efficiency.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a multi-level dynamic spectrum sharing method based on block chain technology. Background technique [0002] At present, a variety of spectrum sharing schemes have been proposed, such as the cognitive radio (Cognitive Radio, CR) scheme, CR equipment senses, detects, and analyzes the surrounding environment, and adjusts its own transmission parameters according to the analysis results; TV White Space (TV White Space) , TVWS) program, based on digital TV gradually replacing traditional analog TV, the idle TVWS frequency band is used for dynamic spectrum access of unlicensed users; Citizens Broadband Radio Service (CBRS) program, CBRS spectrum and carrier LTE, 3550 to 3700MHz of continuous spectrum of 150MHz bandwidth share a three-layer structure. In the above-mentioned schemes, a centralized management structure is often adopted, that is, a highly trusted central ent...
