This book discusses the smooth integration of optical and RF networks in 5G and beyond (5G+) heterogeneous networks (HetNets), covering both planning and operational aspects. The integration of high-frequency air interfaces into 5G+ wireless networks can relieve the congested radio frequency (RF) bands. Visible light communication (VLC) is now emerging as a promising candidate for future generations of HetNets. Heterogeneous RF-optical networks combine the high throughput of visible light and the high reliability of RF. However, when implementing these HetNets in mobile scenarios, several challenges arise from both planning and operational perspectives. Since the mmWave, terahertz, and visible light bands share similar wave propagation characteristics, the concepts presented here can be broadly applied in all such bands.
To facilitate the planning of RF-optical HetNets, the authors present an algorithm that specifies the joint optimal densities of the base stations by drawing on stochastic geometry in order to satisfy the users' quality-of-service (QoS) demands with minimum network power consumption. From an operational perspective, the book explores vertical handovers and multi-homing using a cooperative framework. For vertical handovers, it employs a data-driven approach based on deep neural networks to predict abrupt optical outages; and, on the basis of this prediction, proposes a reinforcement learning strategy that ensures minimal network latency during handovers. In terms of multi-homing support, the authors examine the aggregation of the resources from both optical and RF networks, adopting a two-timescale multi-agent reinforcement learning strategy for optimal power allocation.
Presenting comprehensive planning and operational strategies, the book allows readers to gain an in-depth grasp of how to integrate future coexisting networks at high-frequency bands in a cooperative manner, yielding reliable and high-speed 5G+ HetNets.
商品描述(中文翻譯)
本書討論了在5G及其後續版本（5G+）的異構網絡（HetNets）中，光學和射頻網絡的順暢整合，涵蓋了規劃和運營方面的內容。將高頻空中介面整合到5G+無線網絡中可以減輕射頻（RF）頻段的擁擠。可見光通信（VLC）現在正成為未來一代HetNets的有前途的候選技術。異構的RF-光學網絡結合了可見光的高吞吐量和RF的高可靠性。然而，在移動場景中實施這些HetNets時，從規劃和運營的角度都會面臨一些挑戰。由於毫米波、太赫茲和可見光頻段具有相似的波傳特性，這裡介紹的概念可以廣泛應用於所有這些頻段。
為了促進RF-光學HetNets的規劃，作者們提出了一種算法，通過借鑒隨機幾何的方法來指定基站的聯合最優密度，以滿足用戶的服務質量（QoS）要求並實現最小的網絡功耗。從運營的角度來看，本書探討了使用合作框架進行垂直切換和多重連接。對於垂直切換，它採用基於深度神經網絡的數據驅動方法來預測突然的光學中斷；並且基於這個預測，提出了一種強化學習策略，確保切換期間網絡延遲最小。在多重連接支持方面，作者們研究了來自光學和RF網絡的資源聚合，採用了兩個時間尺度的多智能體強化學習策略來進行最優功率分配。
通過提供全面的規劃和運營策略，本書使讀者能夠深入了解如何以合作方式在高頻段整合未來共存的網絡，從而實現可靠且高速的5G+ HetNets。
