摘要: Device-to-Device(D2D)通信是用于通信網(wǎng)絡(luò)中臨近設(shè)備間直接交換信息的技術(shù)。憑借有效提高頻譜利用率、減輕網(wǎng)絡(luò)負(fù)載、降低通信時(shí)延等特性,D2D技術(shù)已經(jīng)成為解決當(dāng)前高速流量增長(zhǎng)和海量設(shè)備接入的關(guān)鍵技術(shù),其中資源分配作為D2D通信中的重點(diǎn)問(wèn)題之一,也正受到廣泛的研究和討論。首先對(duì)D2D通信技術(shù)進(jìn)行簡(jiǎn)介,其次重點(diǎn)介紹D2D通信中資源分配算法的研究現(xiàn)狀,最后總結(jié)研究中的重難點(diǎn)問(wèn)題,提出未來(lái)研究方向。

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(dòng)通信系統(tǒng)開(kāi)始,無(wú)線通信技術(shù)已經(jīng)歷經(jīng)了幾十年的發(fā)展??梢灶A(yù)見(jiàn)的是,未來(lái)移動(dòng)通信的用戶數(shù)、終端設(shè)備連接數(shù)和數(shù)據(jù)吞吐量還將繼續(xù)呈指數(shù)式增長(zhǎng),這無(wú)疑對(duì)無(wú)線通信技術(shù)的研究提出了更高要求。為應(yīng)對(duì)網(wǎng)絡(luò)密集化、異構(gòu)化、差異化帶來(lái)的挑戰(zhàn),僅寄希望于網(wǎng)絡(luò)或中心設(shè)備完成通信系統(tǒng)內(nèi)大范圍、高效率的指揮是不現(xiàn)實(shí)的,因此無(wú)需中心設(shè)備干預(yù)的D2D(Device-to-Device)通信技術(shù)迅速成為了熱點(diǎn)。
