2.1 GHz频段LTE与WCDMA的干扰共存研究

摘要

It analyzes the adjacent channel interferences between LTE and WCDMA in 2.1 GHz bands by the method of system simula-tion. The LTE and WCDMA simulation parameters are defined in the 3GPP standards. The results of the simulations,which as-sumed cel layouts of uncoordinated macro cel ular deployment and coordinated macro cel ular deployment and 4 LTE channel bandwidths(5,10,15,20 MHz),shows LTE and WCDMA can achieve coexistence if base station and user equipment satisfy the requirements of 3GPP standards and no additional protective measures are needed.%通过系统仿真对2.1 GHz频段的LTE与WCDMA系统在邻频时干扰情况进行研究。采用3GPP标准中定义的LTE和WCDMA仿真参数，对共站和非共站2种LTE与WCDMA相对拓扑场景，以及4种典型的LTE带宽（5、10、15、20 MHz）分别进行仿真。仿真结果显示，非共站时干扰情况最严重。但在2种场景下，基站和终端设备只要满足3GPP标准定义的ACIR要求即可实现LTE FDD与WCDMA的邻频共存，不需要增加额外的保护措施。
