摘要：
The hierarchical cell structure is needed for different requirements: large cells guarantee continuos coverage,:while small cells are necessary to achieve good spectrum efficiency and high capacity. In this paper, 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 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.
