| Abstract(in English) | It is effective to utilize existing spectrum resources in order to realize more advanced mobile communication systems such as 5G. Many studies on spectrum sharing have been conducted. On the other hand, blockchain is attracting attention as a highly reliable management method for distributed data. It is expected to be used in many ways other than trading crypto assets. Some proposals have been made for spectrum sharing. This paper gives an overview of the major spectrum sharing using blockchain so far, and proposes an automatic autonomous distributed dynamic spectrum sharing using blockchain. In our method, secondary users can automatically acquire the shared target spectrum bands without human adjustment by the auction using smart contracts. Furthermore, we have realized a mechanism in which secondary users who share more spectrum usage data required for spectrum sharing have more opportunities to participate in auction. We used CA as a method to use the shared spectrum band, and proposed a method of realizing it by O-RAN on OSS. From the results of implementing and evaluating, we will consider processing time, use cases, and changes in spectrum usage data and the number of bidders. |
