Abstract: Based on a discussion of the requirements for the multiple acess control protocol of beyond third-generation mobile systems, we in this paper articulate the needs of the new multiple acess control protocol with support of high-speed transmission and guaranteed quality of service, for voice, video and audio. In light of these, we present the design of a new multiple acess control protocol, called intelligent slot-subcarriered assignment multiple acess control protocol, to support multiple service categories and to yield high spectral efficiency. Our simulation results verify that intelligent slot-subcarriered assignment multiple acess control protocol can not only provide low delays for the real-time traffic by using bandwidth reservation and effectual scheduling, but also make full use of the limited bandwidth by using a dynamic sub-carrier assignment algorithm. 15 Refs.
