Research On MAC Layer Of IEEE 802.16e Protocol And Its Materialization

In this thesis, we conduct an overall research on the MAC layer of IEEE 802.16e protocol, especially focus on ARQ (Automatic Repeat reQuest), FFB (Fast FeedBack) and MBS (Multicast and Broadcast Service). And software based on the protocol is realized and tested in CHM board. The thesis begins with the introduction to recent mobile communication technologies as well as their developments, followed by a systematic study on the MAC layer of IEEE 802.16e protocol and a detailed research on ARQ, FFB and MBS. Next, a software architecture of WIMAX (Worldwide Interoperability for Microwave Access) based on IEEE 802.16e protocol is given and then the startup flow of the software is introduced. In the software architecture, we focus on DBS (DataBase Subsystem) and CCS (Channel Control Subsystem). At last, the software is tested in CHM board.The main results of this thesis are as follows: A whole research on the MAC layer of IEEE 802.16e protocol is done and a clear architecture of MAC layer is given. In MAC layer, ARQ, FFB and MBS are detailed researched.Based on a systematical study of IEEE 802.16e protocol, the software of WIMAX based on the protocol is analyzed and realized. Firstly, the overall architecture is made. Secondly, we mainly introduced the DBS and CCS and their software materialization. Lastly, the software is tested in CHM board.
