TD-LTE宏微混合组网策略探讨

Discussion on the Strategy of Hybrid Networking of Macrocell and Microcell Networks

在传统的网络架构中,仅使用宏站组网已经不能完全满足TD-LTE室外连续覆盖、室内深度覆盖和高容量高速率的需求。以TD-LTE实验网为环境摸索研究微站在不同应用场景(如室外补盲、室外覆盖室内和补热场景)和组网方案下的性能,并给出宏微同频和异频组网方式下的优化参数配置和微站部署方案建议。

In the traditional networking architecture,macro networking itself cannot meet the requirementsfor continuous coverage of outdoor, deep coverage ofindoor and high-capacity just. This paper explores theperformance of micro Base Station （BS） in differentapplication scenarios （e.g., coverage-expansion, deepcoverage, capacity-expansion） based on TD-LTE experimental network, and provides optimal parametersettings and deployment schemes of micro BS in networking with both same frequency and different frequency.
