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.
Key words : euRLLC;spectrum sharing;6G hybrid cloud;blockchain

    第六代移動(dòng)通信技術(shù)(6G)可以靈活地滿(mǎn)足不同場(chǎng)景下業(yè)務(wù)的特定需求,并將為垂直行業(yè)帶來(lái)各種創(chuàng)新應(yīng)用,提高社會(huì)經(jīng)濟(jì)效率并降低成本[1-2]。5G中的超可靠性和低延遲通信(uRLLC)旨在支持關(guān)鍵任務(wù)應(yīng)用程序,這些應(yīng)用程序要求高可靠性和低延遲[3-7]。當(dāng)然,未來(lái)6G中的uRLLC預(yù)計(jì)將比其5G版本有更好的能力,稱(chēng)為增強(qiáng)uRLLC(euRLLC)。這是由關(guān)鍵任務(wù)應(yīng)用程序(如機(jī)器人和自動(dòng)系統(tǒng))渴望更高的可靠性和更低的延遲驅(qū)動(dòng)的;另一方面,由于更高的可靠性、更低的延遲和更高的數(shù)據(jù)速率,euRLLC在未來(lái)6G中可能會(huì)產(chǎn)生一個(gè)新的應(yīng)用場(chǎng)景,融合物聯(lián)網(wǎng)、大數(shù)據(jù)、云計(jì)算、邊緣計(jì)算、區(qū)塊鏈、頻譜共享、人工智能等,形成新型信息基礎(chǔ)設(shè)施。6G正為產(chǎn)業(yè)、經(jīng)濟(jì)和社會(huì)的數(shù)字化轉(zhuǎn)型帶來(lái)前所未有的動(dòng)力。
