Blockchain based spectrum sharing over 6G hybrid cloud

Abstract： This work investigates the dynamic spectrum sharing in the 6G enhanced ultra-reliable and low latency communications (euRLLC) services, as more and more Internet of Things(IoT) devices need to communicate between each other in the limited spectrum. This paper combines blockchain technology with 6G hybrid cloud to realize the spectrum sharing between IoT devices. Due to blockchain′s distributed storage and credibility, blockchain based dynamic spectrum sharing can achieve flexible, feasible and much more efficient spectrum allocation. This paper analyzes the process of spectrum sharing and proposes a wireless spectrum resource sharing structure in euRLLC based on reinforcement learning(RL), including resource classification, resource scheduling, overall model and neural network optimization. This design integrates blockchain and hybrid cloud to build a public management platform to register and manage the information of IoT devices using unified coding and identification standards.
