Abstract :
We propose a MAC protocol that consists of a channel access mechanism and transmission mechanism to support effective wireless packet data service. In the channel access mechanism, a broadcast channel announces the status information of the random access channel, and the mobile station tries random access based on status information. Also, the mobile station has access probability to prevent collision increase due to the transmission of short messages. For effective transmission, the mobile station changes the transmission rate based on the transmission queue status to adapt the burst traffic characteristics. In restricted environments of transmission code and bandwidth, the proposed protocol shows better performance than the cdma2000 system
