摘要
针对TD-LTE异构网络基站间使用灵活时隙配置技术而出现的不同场景干扰问题,建立相关的TD-LTE异构网络链路仿真平台对干扰进行仿真和分析。研究结果表明:常规时隙下,布置的家庭的数量将影响其对宏基站干扰的大小,且宏基站用户的上行传输受到的干扰较强;较之于常规时隙,在交叉时隙下,宏基站的下行传输受到家庭基站的上行传输的干扰较强。
Based on different interference scenarios of TD-LTE heterogeneous network which use flexible time slot configuration technology.This article establishes a simulating platform of TD-LTE heterogeneous network link to simulate and analyse interference.The results showed that at the regular time slot,the number of arranged families will affect the degree of its interference on macro base station,and the interference gotten by the macro base station uplink transmission is strong,and at the cross time slot compared with the regular time slot,the interference of femtocell uplink transmission on the macro base station downlink transmission is strong.
