摘要

A novel medium access control scheme which can be seamlessly integrated into the mufti-dimension packet CDMA environment is proposed With the basic frame structure unchanged and important system parameters revised; proposed scheme can accommodate more mobile terminals for voice-only cellular traffic when compared to conventional schemes. The predominance of proposed scheme can be reserved no matter how the overall traffic load is distributed System performance of mixed voice/video traffic is also studied for multimedia cellular environment in which video stream can be smoothly introduced by proposed scheme.
