摘要 中国国家工业与信息化部(MIIT)将2.6G频段的2500-2690MHz频率资源规划为TDD频谱,该频段与北斗卫星导航系统用于提供定位报告与短报文(RDSS)业务的2.5G频段的2483.5~2500MHz相邻,D—LTE基站分布密集、功率较大,极有可能对在其覆盖范围内的北斗RDSS业务的用户接收机产生有害干扰。本文以北斗系统和中国4G系统间干扰原理及系统典型参数为基础,根据3GPP LTE TS36系列标准和ITU-R SM.2039建议书,对北斗系统与4G LTE系统之间的干扰进行了分析,并给出兼容分析结论和建议。 The MIIT has assigned the 2.6G band ( 2500 - 2690MHz) to 4G communication service, which is adjacent to the 2.5G band (2483.5 -2500MHz) used by BeiDou system (BDS) to provide RDSS. The base stations of D- LTE are deployed densely and have higher power that could cause harmful interference in their coverage to the RDSS user terminals. Based on the theory of the interference between the BDS and 4G system and the typical system parameters, and according to 3GPP LTE TS36 series standards and ITU - R SM. 2039, the analysis of the interference between the BDS and 4G LTE system is performed, the compatibility analysis results are given and some suggestions are put forward.
