功耗是用于移动的应用的实用毫米波（mmWave）通信设备的最显著的技术障碍之一。100 GHz以上的更高毫米波频段的通信将面临更大的挑战。本文试图提供初始功率估计移动的毫米波设备下的现实参数值和国家的最先进的设备性能特征，以了解这种系统的性能，今天和指导未来的研究。针对多载波新无线电（NR）系统中的用户设备，针对类似于当前5G部署的28 GHz的4×100 MHz系统以及可能在未来6G系统中使用的140 GHz的假设8×200 MHz系统，估计功率。重要的是，该分析考虑了RF前端组件以及数字基带处理部分的功耗。模拟和全数字波束形成也进行了评估。
Power consumption is one of the most significant technical barriers for practical millimeter wave (mmWave) communication devices for mobile applications. Communication in the higher mmWave bands above 100 GHz will face even greater challenges. This paper attempts to provide initial power estimates for mobile mmWave devices under realistic parameter values and state-of-the-art device performance characteristics to understand the performance of such systems today and guide research for the future. Power is estimated for a user equipment in a multicarrier New Radio (NR) system for both a 4×100 MHz system at 28 GHz similar to current 5G deployments as well as a hypothetical 8×200 MHz system at 140 GHz that may be used in future 6G systems. Importantly, the analysis considers power consumption of both the RF front-end components as well as portions of the digital baseband processing. Both analog and fully-digital beamforming are also evaluated.
