Based on detailed working process of UWB-RI MAC, FI frame broadcast interval was analyzed and the support for QoS was explained. Finally, the performance simulation and comparison of UWB-RT MAC and UWB MACAW MAC were given.

通过给出的UWB-RI MAC协议数据收发的详细流程，分析了FI帧广播间隔的取值，说明其对QoS的支持；最后仿真比较了UWB-RI MAC和UWB-RI MAC和UWB MACAW MAC的性能。

First, the stations'timing process and the slot aligning are discussed. Second, the dissertation propose a resource request random access method based on feedback. The performances of this method are analyzed. Third, proceed from the considerations of the MAC protocol for the HFC system, a QOS-oriental scheduling algorithm for the MAC protocol based on dynamic TDMA is proposed. Simulation results show that the performance of this algorithm is better than that of the first come first service. Forth, two contention resolution algorithms ----p-persistent CRA and tree CRA, which are usually adopted in the HFC system, are summarized. The delay and characteristic are compared. At last, the dissertation introduces the function implementation of the MAC layer based on COM21 UPSTREAMS.

首先，讨论了基站的同步进程和时隙同步的实现；然后，本文提出了一种带反馈模块的资源申请信号随机接入方法，并对其进行性能分析；然后，从HFC系统的MAC协议出发，提出了一种用于基于动态TDMA技术的MAC协议的业务安排算法，计算机仿真结果表明其性能优于先到先服务法的性能；然后概述了常用于HFC系统的两种冲突解决算法——p-坚持冲突解决算法和树型冲突解决算法，比较两者的时延性能与特征；最后，介绍了基于COM21 UPSTREAMS协议的MAC层功能实现，给出了硬件框图和照片。

Key words:Reverse Address Resolution Protocol Reverse Address Resolution Protocol discovers the identity of the IP address for diskless machines by sending out a packet that includes its MAC address and a request for the IP address assigned to that MAC address.

逆向地址解析协议可以通过发送一个包含有无盘主机MAC地址的数据包，来询问与此MAC地址相对应的IP地址。

AppleTalk has the advantage when you're using a Mac that it's well integrated into the rest of the Mac system.

The High Speed Uplink Packet Access technology includes Adaptive Modulation and Coding, Hybrid Automatic Repeat Request, and Node B fast scheduling. It also solves the problem of sharing the uplink channel resources for User Equipment. Moreover, it has Medium Access Control protocol entities (MAC-e and MAC-es) to enhance and optimize the protocol.

为了改善上行性能，高速上行分组接入主要考虑的技术包括自适应调制编码、混合自动重传、节点B快速调度，以及用户终端如何共享上行信道资源，同时包括增加增强的媒体访问控制实体，对协议进行增强和优化。
