Recently, the concept of wake-up radio based access has been considered as an effective power saving mechanism for 5G mobile devices. In this article, the average power consumption of a wake-up radio enabled mobile device is analyzed and modeled by using a semi-Markov process. Building on this, a delay-constrained optimization problem is then formulated, to maximize the device energy-efficiency under given latency requirements, allowing the optimal parameters of the wake-up scheme to be obtained in closed form. The provided numerical results show that, for a given delay requirement, the proposed solution is able to reduce the power consumption by up to 40% compared with an optimized discontinuous reception (DRX) based reference scheme.

延迟约束下 5G 中基于唤醒无线电的接入:建模和优化

最近,基于唤醒无线电的接入概念被认为是 5G 移动设备的有效节能机制。在本文中,使用半马尔可夫过程分析和建模支持唤醒无线电的移动设备的平均功耗。在此基础上,然后制定延迟约束优化问题,以在给定延迟要求下最大化设备能效,从而允许以封闭形式获得唤醒方案的最佳参数。提供的数值结果表明,对于给定的延迟要求,与基于优化的非连续接收 (DRX) 的参考方案相比,所提出的解决方案能够将功耗降低多达 40%。
