A Joint Packet Reservation and Status Sensing Multiple Access for Voice/Data Integrated CDMA networks

摘要

In this paper, a medium access control protocol is proposed for the integrated voice and data services in the lo- cal CDMA communication systems. Based on WB-TD/CDMA, uplink channels for the proposed protocol are composed of time slots with multiple spreading codes for each slot. During a talk- spurt, a voice terminal transmits its entire packets over a reserved code. On the other hand, a data terminal transmits its packet after sensing the spreading code status.
