摘　　要：介绍了MAC层(media access controc)相关协议内容,重点分析OAI(OpenAirInterface)系统平台的缺陷,基于OAI平台搭建了LTE(long term evolution)频分双工(frequency division duplexing,FDD)通信系统MAC层仿真平台。该平台完全按照第三代合作伙伴项目(the 3rd generation partnership project,3GPP)物理层(physical layer,PHY)与MAC等协议进行搭建,更加符合真实的通信系统,可进行协议内容如随机接入、调度与复用解复用等方面的仿真验证实验,可为性能、算法以及相关流程研究提供有力保证。This paper presents the protocol details about MAC layer, analyzes the defect of OAI system and builds LTE FDD communication system testbed for MAC in terms of OAI platform. The testbed is based on 3GPP PHY layer and MAC protocol according to the real communication environment, on which researchers can conduct simulation experiments about RA, scheduling, multiplexing and so on. The presented testbed provides wonderful performance for the research on algorithm in protocol process.
