摘要
以450-470 MHz共存场景为基础,对450-470 MHz频段内LTE系统与铁路集群系统干扰情况、LTE系统内LTE-FDD与LTE-TDD干扰情况进行了分析,得到了相应的隔离度需求;在综合考虑各种频段划分方案的隔离度需求基础上,提出了采用全FDD方式的划分方案的建议;最后对450-470 MHz在室内外的部署策略进行了初步探讨。
Based on the coexistence scenarios in 450-470 MHZ band, it analyzes the inter-system interference and calculates the isolation between LTE-FDD, LTE-TDD and railway-schedule system by theoretical method. Based on the isolation demand, it suggests a LTE-FDD deployment scheme and discusses the tactic of the LTE deployment for indoor and outdoor scenarios.
