摘　　要：文章分别针对异构的无线网络和同构的广域与局域同覆盖无线网络的场景,研究基于协同覆盖的绿色网络技术。该技术能通过网络间的协同以及小区间的协同,减轻重复覆盖所带来的能效比降低问题。仿真结果表明,文章提出的基于协同覆盖的绿色无线网络技术在系统能效比以及用户接入成功率方面有较明显的增益。This paper examines green network technologies using cooperative coverage. In both heterogeneous wireless networks and homogeneous wide area/local area networks, this technology can reduce the effect of low energy efficiency caused by coverage duplication. This is achieved by forming network cooperatives and residential district cooperatives. Simulation shows that the proposed green wireless technologies significantly improve energy efficiency and access success rate for users.
