论文摘要
能源效率（EE）是第五代（5G）和5G（B5G）无线通信系统的主要性能指标，尤其是对于超密集网络。本文提出了端到端（E2E）功耗模型，并研究了异质B5G细胞结构的能源效率，该结构将超密集网络中的室内和室外通信方案分开。在这项工作中，在常规的6 GHz频率上进行大量多输入 - 元素输出（MIMO）技术用于长距离户外通信。部署了光照（LIFI）和毫米波（MMWave）技术，以为室内用户提供高数据速率服务。鉴于，在引用的未分离系统中，室内用户直接与室外大型MIMO宏观基站进行通信。根据总功耗和能源效率对这两个系统的性能进行了评估和比较。结果表明，与非分离通信方案相比，将室内和室外通信分开的网络体系结构可以支持更高的数据速率传输，以减少能源消耗。此外，结果表明，部署LIFI和MMWave IAP可以使用户以更高的数据速率传输并进一步改善EE。
Energy efficiency (EE) is a major performance metric for fifth generation (5G) and beyond 5G (B5G) wireless communication systems, especially for ultra dense networks. This paper proposes an end-to-end (e2e) power consumption model and studies the energy efficiency for a heterogeneous B5G cellular architecture that separates the indoor and outdoor communication scenarios in ultra dense networks. In this work, massive multiple-input-multiple-output (MIMO) technologies at conventional sub-6 GHz frequencies are used for long-distance outdoor communications. Light-Fidelity (LiFi) and millimeter wave (mmWave) technologies are deployed to provide a high data rate service to indoor users. Whereas, in the referenced nonseparated system, the indoor users communicate with the outdoor massive MIMO macro base station directly. The performance of these two systems are evaluated and compared in terms of the total power consumption and energy efficiency. The results show that the network architecture which separates indoor and outdoor communication can support a higher data rate transmission for less energy consumption, compared to non-separate communication scenario. In addition, the results show that deploying LiFi and mmWave IAPs can enable users to transmit at a higher data rate and further improve the EE.
