作为第五代无线通信（5G）系统的有前景的范例，雾无线电接入网络（F-RAN）已经被提出作为先进的社会感知移动的联网架构，以提供高频谱效率（SE）同时保持高能量效率（EE）和低延迟。F-RAN的性能分析和无线资源分配是F-RAN成功部署的基础。本文综述了F-RAN的性能分析和无线资源分配的最新进展。特别地，提出了先进的边缘缓存和自适应模型选择方案，以在保持低延迟水平的情况下提高SE和EE。分别提出了F-RAN中优化SE和EE的无线资源分配策略。还确定了基于F-RAN的5G架构和社会感知技术方面的一些开放问题。
As a promising paradigm for the fifth generation wireless communication (5G) system, the fog radio access network (F-RAN) has been proposed as an advanced socially aware mobile networking architecture to provide high spectral efficiency (SE) while maintaining high energy efficiency (EE) and low latency. Recent advents are advocated to the performance analysis and radio resource allocation, both of which are fundamental issues to make F-RANs successfully rollout. This paper comprehensively summarizes the recent advances of the performance analysis and radio resource allocation in F-RANs. In particular, the advanced edge cache and adaptive model selection schemes are presented to improve SE and EE under maintaining a low latency level. The radio resource allocation strategies to optimize SE and EE in F-RANs are, respectively, proposed. A few open issues in terms of the F-RAN-based 5G architecture and the social-awareness technique are identified as well.
