An MAC protocol with reservation and channel sennsing for the integrated voice/data packet CDMA networks
In-Taek Lim · 1999
A medium access control protocol is proposed and analyzed under the integrated voice and data services in the microcellular packet CDMA networks. The protocol follows the channel reservation and status sensing mechanisms. The base station broadcasts the uplink channel status information. Based on the channel status information, a voice terminal can reserve a spreading code to transmit voice packets during a talkspurt while a data terminal has to contend for a code for each packet transmission. The numerical results show that the proposed protocol can improve the system capacity, while guaranteeing the QoS of voice and data services.
