隨著通信技術(shù)的進步,用戶和應(yīng)用的數(shù)量呈指數(shù)級增長,導(dǎo)致了資源的稀缺和功耗的增加�；旧系臄�(shù)據(jù)流量也隨著用戶數(shù)量的增加而增加。為了降低5G中蜂窩用戶的中斷概率,設(shè)備到設(shè)備（D2D）通信被認(rèn)為是一個突出的解決方案。本文研究了D2D通信的模式選擇和資源分配及其對網(wǎng)絡(luò)關(guān)鍵性能指標(biāo)的影響。該研究揭示了當(dāng)蜂窩網(wǎng)絡(luò)中可以形成和管理D2D用戶群時,D2D以外的機會通信在提高能量效率、公平性和容量方面的巨大潛力。在蜂窩網(wǎng)絡(luò)中引入D2D鏈路將帶來許多技術(shù)問題。如D2D設(shè)備發(fā)現(xiàn)和鏈路建立、模式選擇、資源分配和移動性管理。為了解決它們之間的共存問題,本文將重點研究蜂窩網(wǎng)絡(luò)下的D2D模式選擇和資源分配問題。目前對D2D通信的許多研究都是基于傳統(tǒng)的通信模式:蜂窩模式、D2D共享模式和D2D專用模式。本文研究了新的D2D通信方式:本地路由方式、直接D2D方式和中繼輔助D2D方式,對單小區(qū)基站的負(fù)載狀態(tài)進行了分類,并針對不同層次設(shè)計了相應(yīng)的通信方式。根據(jù)基站單小區(qū)的全網(wǎng)負(fù)荷,將其分為非滿負(fù)荷和滿負(fù)荷兩種狀態(tài),將非滿負(fù)荷分為低負(fù)荷和中負(fù)荷。詳細(xì)分析了不同負(fù)載條件下D2D用戶復(fù)用蜂窩用戶上行資源的干擾。首先,考慮低負(fù)載下...
