Abstract

A joint code division multiple access and noncollision packet reservation multiple access (JCDMA/NC-PRMA) protocol is proposed and investigated as an uplink access scheme for the third-generation mobile systems. Being the underlying TDMA architecture of the CDMA transmissions, NC-PRMA enables the base station to have a centralized control over the slot allocation policy. In order to reduce the multiple access interference (MAI) variation in CDMA transmission, load balancing (LB) slot assignment policy is proposed and evaluated. Simulation results show that considerable improvement can be achieved over the joint code division multiple access and packet reservation multiple access (JCDMA/PRMA) protocol, in which the multiple access interference variation is reduced by way of a dynamic permission probability for contending terminals
