摘要

本文基于无线通信网络工程中的规划技术

针对TD-LTE系统传输基本单元资源块

将规划技术与资源块相融合

提出基于规划的TD-LTE时频联合干扰协调技术

突破了单纯从频率或时间维度上对资源规划的限制

同时结合用户调度、功率控制等辅助技术以提高干扰抑制性能。文中给出了基于3GPP标准仿真平台的性能对比

最后讨论并分析了该方案的技术优势

并指出该技术可以应用于频谱共享场景下TD-LTE组网中的干扰抑制。

Abstract

TD-LTE is the trend and direction of TD-SCDMA.The common interference mitigation of LTE network has weaker adaptation to network load variation

higher complication to application and more cost for system.This paper proposes a new technique

called TD-LTE time and frequency resource combined interference mitigation

which is based on the planning technique of wireless communication engineering.This new technique utilizes the basic transmission resource unit of TD-LTE and integrates user equipment schedule and power control to promote the performance of interference management.It reports the performance contrast of different systems

according to 3GPP specification

discusses and analyses the technique advance and then points out that this technique could be applied to the TD-LTE network interference management of spectrum sharing.
