摘　　要：　讨论了IEEE802 15 3无线个域网媒体接入控制协议的基本特点,提出了针对超宽带物理层的可能改进方法,包括增加虚拟载波侦听以提高超宽带系统载波侦听困难的缺点、设计协议加速器以适应高速的物理层速率和基于网络拓扑的微微网控制器选举等.The important features of IEEE 802.15.3 Wireless Personal Area Network medium access control protocol are pointed out. As for the forthcoming IEEE 802.15.3a ultra-wide band physical layer, corresponding possible modifications to improve media access control layer performance are proposed,including adding virtual carrier sense to compensate the drawback of relatively high failure rate of UWB physical layer carrier sense, designing protocol accelerator to adopt to the very high data rate and topology-base piconet controller selection, etc.
