Recently, code division multiple access scheme with time division duplex(CDMA/TDD)has drawn considerable attention as means to realize efficient wireless multimedia communications system. In this paper, we propose two time slot allocation algorithms for CDMA/TDD systems to efficiently accommodate multimedia traffic. Assuming a practical multiple cell environment and a multimedia service model which consists of several kinds of circuit-switched and packet-switched services with different quality of services(QoSs), we evaluate the average delay(average time from call generation to channel assignment)of the CDMA/TDD system with the proposed algorithms, and compare the performance with that of CDMA with frequency division duplex(CDMA/FDD)and time division multiple access with TDD(TDMA/TDD)systems. Our computer simulation results show that the CDMA/TDD system with one of the proposed algorithms, which can effectively avoid interference among users with different QoSs, can improve the average delay performance as compared with the other systems.
