Method and system for sharing distributed frequency spectrum

Abstract

The invention discloses a method used for the sharing of frequency spectrum in a plurality of distributed systems. The method comprises the following steps of: adopting one system of a plurality of the systems to send instruction information instructing a corresponding time slot used for a corresponding system to broadcast payment information and network utility functions used for a plurality of the systems to other systems; adopting the corresponding time slot instructed by the received instruction information to broadcast the self payment information to other systems in each of a plurality of the systems; determining corresponding frequency spectrum sharing proposals according to the self payment information and the received payment information; and selecting and adopting a frequency spectrum sharing proposal reaching the maximum network effectiveness from the determined frequency spectrum sharing proposals. The invention also discloses a system for carrying out the distributed frequency spectrum sharing with a plurality of other systems. The invention avoids low effectiveness and unfairness caused by determining frequency spectrum sharing proposals in series by systems, reduces signal overhead and frequency spectrum waste, and realizes the optimal network performance.

Description

technical field [0001] The present invention relates to spectrum resource sharing technology, in particular to a method and system for distributed spectrum sharing. Background technique [0002] In the prior art, in order to solve the problem of radio frequency spectrum shortage, a spectrum sharing technology is usually used. Using spectrum sharing technology, multiple systems can share common radio resources through time domain separation, frequency domain separation or space domain separation. [0003] In order to share spectrum resources among multiple systems, there are centralized and distributed network architectures. Correspondingly, according to different network topologies used, spectrum sharing technologies can be divided into two categories: centralized spectrum sharing and distributed spectrum sharing. [0004] In the case of centralized spectrum sharing, a central entity is required to coordinate spectrum sharing, interference control and optimization of spect...

Problems solved by technology

Although network-level optimization is possible in this case, the disadvantage of this centralized approach is that the need for this central entity, in addition to its additional deployment, limits the scalability of the network and flexibility

Therefore, this process of information feedback and exchange consumes considerable spectrum resources, resulting in significant signal overhead and spectrum waste
