B5G超密集网络端到端能效评估
End-to-End Energy Efficiency Evaluation for B5G Ultra Dense Networks
摘要：
能量效率（EE）是第五代（5G）和超5G（B5G）无线通信系统的主要性能度量，特别是对于超密集网络。本文提出了一种端到端（e2e）功耗模型，并研究了异构B5G蜂窝架构的能源效率，该架构在超密集网络中将室内和室外通信场景分开。在这项工作中，大规模的多输入多输出（MIMO）技术在传统的子6 GHz频率用于长距离户外通信。部署光保真（LiFi）和毫米波（mmWave）技术以向室内用户提供高数据速率服务。然而，在所参考的非分离系统中，室内用户直接与室外大规模多输入多输出宏基站通信。这两个系统的性能进行评估和比较的总功耗和能源效率。结果表明，与室内室外通信分离的情况相比，室内室外通信分离的网络架构能够以更少的能耗支持更高的数据速率传输。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，并进一步提高EE。
英文摘要：
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.
