LTE FDD容量规划研究

摘要

The corresponding factors that impact LTE FDD capacity are analyzed. The CP overhead, the uplink and downlink signaling overhead ratio, the number of users that can be scheduled simultaneously and VoIP(Voice over Internet Phone) users of LTE FDD system are presented. Specific calculation model and methods of indicators are given. Based on 15MHz system bandwidth, LTE FDD calculation cases are provided in order to be useful to the capacity design of LTE FDD wireless network system.%重点分析了影响LTE FDD容量的相关因素；在此基础上，分析了LTE FDD系统的CP开销、上下行链路信令开销占比、同时可调度用户数及VoIP用户数，给出了各项指标的具体计算模型及方法；针对15MHz的系统带宽，给出了LTE FDD的计算案例，以帮助LTE FDD无线网络系统容量规划设计。
