Abstract: Device-to-Device(D2D) communication is a technology used to directly exchange information between neighboring devices in a communication network. With the characteristics of effectively improving spectrum utilization, reducing network load, and reducing communication delay, D2D technology has become a key technology to solve the current high-speed traffic growth and mass device access. Among them, resource allocation is one of the key issues in D2D communication,which is being extensively studied and discussed. This article first introduces the D2D communication technology, secondly focuses on the research status of the resource allocation algorithm in D2D communication, and finally summarizes the major and difficult problems in the research and proposes future research directions.
Key words : 5G;D2D;spectrum utilization;resource allocation

從第一代模擬移動通信系統開始,無線通信技術已經歷經了幾十年的發展。可以預見的是,未來移動通信的用戶數、終端設備連接數和數據吞吐量還將繼續呈指數式增長,這無疑對無線通信技術的研究提出了更高要求。為應對網絡密集化、異構化、差異化帶來的挑戰,僅寄希望于網絡或中心設備完成通信系統內大范圍、高效率的指揮是不現實的,因此無需中心設備干預的D2D(Device-to-Device)通信技術迅速成為了熱點。
