在下一代移动系统中，高密度的小蜂窝网络将被部署以满足移动业务的巨大增长，其中干扰是一个关键限制。干扰对齐(IA)是一种潜在的小蜂窝网络干扰管理技术。然而，仍有一些实际挑战阻碍了基于IA的小蜂窝网络的发展。另一方面，为了更好地应对从发送者驱动的端到端通信范式向接收者驱动的内容检索范式的转变，以内容为中心的传播受到了极大的关注。随着计算领域的最新进展，一种面向移动网络的面向3C的设计范例正在出现。本文提出了一种基于智能网的面向3C的小蜂窝网络框架，该框架利用缓存和计算来简化网络拓扑结构，提高吞吐量，降低回程负载，保证用户体验质量。此外，还讨论了具有IA的面向3C的小蜂窝网络的一些研究挑战。
In future generation mobile systems, hyperdense small cell networks will be deployed to meet the tremendous growth of mobile traffic, in which interference is a key limitation. Interference alignment, IA, is a potential technique for interference management of small cell networks. However, there are still some practical challenges that hinder the development of IA-based small cell networks. On the other hand, to better cope with the shift from the sender-driven end-to-end communication paradigm to the receiver-driven content retrieval paradigm, content-centric communication has attracted great attention. Together with recent advances in computing, a communications, caching, and computing - 3C - oriented design paradigm for mobile networks is emerging. In this article, we propose a framework of 3C-oriented small cell networks with IA, in which caching and computing are exploited to simplify the network topology, improve the throughput, reduce the backhaul load, and guarantee the quality of experience of users. Furthermore, some research challenges are discussed for 3C-oriented small cell networks with IA.
