摘要
本文通过研究TD-LTE与TD-SCDMA两个TDD系统邻频共存的组网要求及数据用户的业务模型,发现受限于TD-LTE标准中特殊子帧的配置,TD-LTE系统业务子帧2∶2调整至1∶3后整体效率较低,经过深入分析找出了最佳的配置。通过增加TD-LTE特殊子帧配比的选项,可有效提高TD-LTE下行系统容量、节省TD-LTE建网成本、并有力的促进TD-SCDMA与TD-LTE两网协调发展,具有较高的现实意义。
Due to the restriction of the special subframe configuration of frame structure type2(TDD type) in the 3GPP LTE protocol,when TD-LTE system coexists with TD-SCDMA system on adjacent frequency and 2:2 subframe configuration is employed in TD-LTE system,the frequency efficiency of TD-LTE system is reletively low.Through analyzing the networking and business models of TD-LTE and TD-SCDMA systems,the best subframe configuration of TD-LTE system is put forward in this paper.This can largely increase the downlink...
