为了解决TDD方式本身所固有的小区间上下行链路比例不一致导致的干扰问题,提出了一种新的信道分配方案,它借助位置信息来判断被考察的信道是否可行,从而减小掉线率,提高整个系统的容量。仿真给出的结果证实该方案是有效的。

It's well known that the mobile stations will comprise a wide range of radio access technologies(RAT), providing user with flexible and efficient access to multi-media service and high data rate communications. Although much work has been done for coexistence analysis between different systems base stations(BS), most of them have not addressed the interference within multi-mode terminal. Hence, for filling the gap, The authors in the article present coexistence studyies of digital cellular system at 1 800 MHz(DCS1800) and time division duplex long term evolution(TDD-LTE) network in multi-mode terminal with multi-service provisioning. A new system model for coexistence was introduced and how deterministic analysis can be done within the terminal was explained. The interference evaluation model was given based on relations between reference sensitivity and signal-to-noise ratio(SNR), which is also deduced. The system simulation methodology was provided and assumption used in simulation was given. Simulation results were shown with different system parameters. Numeric results indicate that multi-mode terminal is mainly affected by local interference. The minimum antenna isolation required for a health system operation was provided. 展开更多
