主要内容:
The proliferation of new applications, e.g., mobile TV, Internet gaming, large file transfer, and the development of user terminals, e.g., smart phones, notebooks, etc., has dramatically increased user traffic and network load. As the spectral efficiency of a point-to-point link in cellular networks approaches its theoretical limits, there is a need for increase in the node density to further improve network capacity and coverage to address the ever increasing traffic demand. Furthermore, the fast growing data traffic and dramatic expansion of network infrastructures will inevitably trigger tremendous escalation of energy demand and energy consumption in wireless networks, which will directly result in the increase of greenhouse gas emission and poses ever increasing threats to the environmental protection and sustainable development. Green evolution has become another urgent need for wireless networks today. The wireless network research should meet the challenges raised by the high demand of both wireless traffic and energy consumption. This talk discusses the need for such an alternative strategy, where low power nodes are overlaid within a macro network, creating a wireless Heterogeneous Network (HetNet). In this tutorial we explore a broad scope of technical areas that are under investigation in the context of HetNets. These areas include node/client cooperation, interference management, mobility, green radio, applications and services. This tutorial shall provide deep insights into the motivations and technology enablers for the emerging area as well as the HetNet development and deployment status.
