摘要

不同的需求需要分层小区结构:大小区保证连续覆盖，而小小区则需要获得良好的频谱效率和高容量。本文研究了一种宏/微蜂窝结构的CDMA系统。在宏/微叠加小区环境中，提出了一种根据时变流量分布控制小区大小的自适应方案。其目的是使宏小区和微小区的通信质量都达到目标质量水平。仿真结果表明，该方案有效地控制了时变流量波动，提高了性能。

Power control and QoS of a CDMA based hierarchical cell structure network

The hierarchical cell structure is needed for different requirements: large cells guarantee continuous coverage, while small cells are necessary to achieve good spectrum efficiency and high capacity. In this paper a CDMA system in macro/micro cell structure is investigated. We propose an adaptive scheme of controlling cell size according to time-varying traffic distribution in a macro/micro overlaid cell environment. This aims to bring communications quality in both macro-cell and micro-cell to a target quality level. Simulation results show that the proposed scheme effectively controls the time-varying traffic fluctuations and provides an enhanced performance.
