摘要

摘要

En 中文
5g会是什么？它不会是4g的增量进步。前四代蜂窝技术都是一次重大的范式转变，打破了向后兼容性。事实上，5g将需要一个范式转变，包括非常高的载波频率和巨大的带宽，极端的基站和设备密度，以及前所未有的天线数量。然而，与前四代不同的是，它也将是高度集成的: 将任何新的5g空中接口和频谱与LTE和WiFi捆绑在一起，以提供普遍的高速率覆盖和无缝的用户体验。为了支持这一点，核心网络还必须达到前所未有的灵活性和智能化水平，频谱监管需要重新考虑和改进，能源和成本效率将成为更加关键的考虑因素。本文讨论了所有这些主题，确定了未来研究和初步5g标准化活动的关键挑战，同时全面概述了当前文献，特别是本期特刊中出现的论文。
