Study on Co-Existence of Macro WCDMA Cell and Micro HSUPA Cell

In this paper, a static system level simulator is used to investigate the capacity loss in case of co-existence of macro WCDMA and micro HSUPA. The capacity loss under different frequency spacing or ACIRs is obtained. The simulation results show that the micro HSUPA cell has little impact on the macro WCDMA cell with frequency spacing of 5 MHz, while the macro WCDMA cell has larger impact on the micro HSUPA cell. Based on simulation, suggestions of frequency planning and parameter setting are given to avoid large capacity loss due to co-existence.
