摘要:

在探讨D2D对通信技术未来发展的导向作用基础上,明确了影响D2D系统设计的多个因素,即D2D设备发现、资源分配、缓存技术、D2D-MIMO。从而勾画出基于D2D技术的光纤前传和软件定义网络实现数据/控制分离的扁平化5G 架构,提出负责接入的下层宏/小基站蜂窝网和负责管理的上层网络云的管理机制。将 D2D技术、SDN技术、边缘计算和物联网技术等关键技术引入未来移动通信网络已经成为研究领域的热点,针对与之相关的、未来大规模网络的移动性、QoS和大数据特性进行了讨论。

Abstract:

On the basis of exploring D2D's leading role to developing trend of communication technologies in the future, some issues in terms of D2D system design are illustrated, like D2D device discovery, resource allocation, caching tech-nology and D2D-MIMO. Thereupon, the outline of separate data/control flattening 5G framework based on D2D is drawn, on the basis of optical fiber fronthaul and software defined network techniques. The mechanism, the lower macro/small base stations for access whereas the upper network cloud for management, is proposed. What emerges is that still major issues shall be faced by the research community, as D2D, SDN, edge computing and IOT technologies are expected to be introduced into the future mobile communication networks. The most relevant techniques for the future large-scale net-works, such as mobility, QoS and big data behavior, are addressed in details.

Key words: D2D, 5G, IoT, edge computing, MIMO
