This paper discusses intelligent and flexible radio access/transmission technologies necessary to smoothly upgrade supported services as well as to economically extend coverage and operational environments. After brief discussion on classification of key technologies for intelligent and flexible radio access/transmission technologies this paper will discuss the adaptive transmission parameter control techniques for both time division multiple access (TDMA) based and code division multiple access (CDMA) based systems. Finally, this paper will propose a new time division multiplexing (TDM) based adaptive access control technique to further enhance system capacity as well as to introduce higher-grade services for CDMA-based wireless multimedia communication systems.
