摘　　要：LTE网络现已规模化建设,其业务速率是指导网络规划的基础。通过分析LTE物理资源块以及信令格式,并对FDD LTE与TD-LTE的常规CP和扩展CP去除开销的上行各种Preamble格式峰值业务速率和下行的峰值业务速率进行仿真以及分析,得到了两种制式不同CP方式的速率差异。LTE network is the scale construction, whose traffic rate is the basis of network planning. LTE physical resource block and signalingformat are analyzed. In addition, the upside peak traffic rate with various Preambleformats and the downside peak traffic rate of normal CP and extended CP without the overhead for FDD LTE and TD-LTE are simulated and analyzed, and the rate differences between the two different CP ways are acquired.

关 键 词：物理资源块 Preamble格式 峰值业务速率
