TD-LTE特殊子帧配比的优化设计

摘要

In the study of TD-LTE and TD-SCDMA systems with the same band networking, in order to avoid co-channel interference between the adjacent time slots, the time slot switching point of the TD-LTE and TD-SCDMA must be aligned. The traditional alignment model of sub-frame configuration will affect the network capacity of TD-LTE. Therefore, a new optimized model of special sub-frame ratio is proposed, which can effectively improve the TD-LTE downlink system capacity and resource utilization. The proposed model provides a constructive reference to the joint development of TD-SCDMA and TD-LTE networks.%在研究TD-LTE与TD-SCDMA异系统同频段组网时，为避免同频相邻时隙间的干扰，要求TD-LTE和TD-SCDMA系统时隙转换点必须对齐，而传统的子帧配比对齐方式会对TD-LTE的网络容量产生影响。基于此，通过进一步对规避交叉时隙干扰的方法进行研究分析，提出了一种特殊子帧配比优化的新模式，可以有效提高TD-LTE下行系统容量和资源利用效率，有力地促进TD-LTE与TD-SCDMA两网协同发展。
