本文通过应用动态无线覆盖来研究宽带码分多址（WCDMA）移动的通信网络中的业务负载均衡问题。通过调整天线阵列的辐射方向图来实现动态覆盖，并采用专门设计的算法在小区之间协同进行覆盖优化。与以前的工作相比，讨论开始于如何将该方法应用于更丰富的模型，其中由于地形的传播效应，因此引入了映射过程，使用路径损耗信息而不是使用地理位置来构建交通模式。然后，本文继续研究的机制，在形成的辐射方向图的线性阵列。最后，仿真结果被用来检查采用合作覆盖的网络的系统级性能。
This paper examines the issues of traffic load balancing in wideband code division multiple access (WCDMA) mobile communication networks through applying dynamic radio coverage. Dynamic radio coverage is achieved by adjusting radiation patterns of antenna arrays and the optimization of coverage is carried out cooperatively between cells using dedicatedly designed algorithm. In comparison with previous work, the discussion starts at how to apply the method to richer models, where propagation effect due to terrain is present A mapping process is therefore introduced to build traffic pattern using path loss information instead of using geographic locations. The paper then goes on to examine the mechanisms involved in the shaping of radiation patterns for a linear array. Finally, simulation results are used to examine the system level performance of a network employing cooperative coverage.
