摘要
在短短的几十年中，移动通信实现了从概念提出到全球普及应用的飞速发展，目前已深刻地改变了人们的生活和工作方式，成为个人与信息网络相连接的最重要纽带之一。然而，目前适用于移动通信的频谱资源已经分配殆尽，而用户密集化、业务海量化的趋势对网络在单位面积上所支持的总容量的需求不断攀升。单纯依靠物理层传输技术的改良和平面蜂窝网络架构的演进，已经很难满足这种需求。密集立体覆盖，作为一种依托未来城市形态而产生的全新网络架构，有望提供一种在平面之外的第3个维度进行复用的全新频谱复用方式，大幅度提升移动通信网络的频谱效率。本文拟初步探讨密集立体覆盖移动通信中的若干基础问题，阐明“物理”和“逻辑”立体网络中的若干挑战及可能的应对方法。
Abstract
Within just a few decades
mobile communications have undergone a rapid growth from its initial concept to the worldwide prosperity
and essentially changed people's daily life as well as the way of working and thinking
thereby becoming the most important connection between individuals and information networks. Although almost all the spectrum resources have been devoted to mobile communications
the demand of higher capacity over a unit area is still increasing
due to the trend that the density of mobile users is increasing and the amount of traffics grow explosively. No doubt such an ever-increasing demand cannot be met by simply relying on the improvement of either physical layer transmission techniques or planar cellular infrastructures. As an emerging network architecture aiming to future metropolitan patterns
3-deminsional dense coverage is expected to provide a novel spectrum reuse methodology
significantly improving the spectrum efficiency of mobile communication systems through spectrum reuse in the third dimension beyond the planar dimensions. Some fundamental problems of 3-deminsional dense coverage oriented mobile communications systems were investigated
the key challenges was pointed out
and possible solutions for 3-deminsional networks from both the physical and logical perspectives were provided.
