5G网络中节能低延迟移动设备的新型唤醒方案
Novel Wake-up Scheme for Energy-Efficient Low-Latency Mobile Devices in 5G Networks
摘要：
改进的移动终端电池寿命和延迟最小化是增强移动宽带服务和用户体验的关键要求。长期演进（LTE）网络已经采用非连续接收（DRX）作为延长电池寿命的基线解决方案。然而，在每个DRX周期中，移动终端基带处理单元监视并解码控制信令，因此没有任何实际数据分配的所有实例导致不必要的能量消耗。这一事实连同长的启动和断电时间停机时间可以防止采用频繁的唤醒时刻，这又导致相当大的延迟。在这项工作中，描述和研究了一种新的唤醒方案，以解决未来5G网络中延迟和电池寿命之间的权衡，从而寻求促进始终可用的体验，而不是始终在线。分析和基于仿真的结果表明，所提出的方案是一种有前途的方法来控制用户平面延迟和能耗，当设备运行在省电模式下。本文的目的是描述唤醒系统的总体工作原理和相关的信令方法，接收器处理解决方案和基本实现方面。此外，通过对系统能效和延迟特性的分析，特别强调未来5G级移动设备，显示并展示了与基于DRX的系统相比的优势
英文摘要：
Improved mobile device battery lifetime and latency mini-mization are critical requirements for enhancing the mobile broadband services and user experience. Long-term evolution (LTE) networks have adopted discontinuous reception (DRX) as the baseline solution for prolonged battery lifetime. However, in every DRX cycle, the mobile device baseband processing unit monitors and decodes the control signaling, and thus all instances without any actual data allocation leads to unnecessary energy consumption. This fact together with the long start-up and power-down times can prevent adopting frequent wake-up instants, which in turn leads to considerable latency. In this work,a novel wake-up scheme is described and studied, to tackle the trade-off between latency and battery lifetime in future 5G networks, seeking thus to facilitate an always-available experience, rather than always-on. Analytical and simulation-based results show that the proposed scheme is a promising approach to control the user plane latency and energy consumption, when the device is operating in the power saving mode. The aim of this article is to describe the overall wake-up system operating principle and the associated signaling methods,receiver processing solutions and essential implementation aspects. Additionally, the advantages compared to DRX-based systems are shown and demonstrated, through the analysis of the system energy-efficiency and latency characteristics, with special emphasis on future 5G-grade mobile devices
