Future CDMA cellular mobile systems supporting multi-service operation

The two major requirements of future cellular mobile and personal communication systems are: the support of multi-rate services and operation in multi-cell environments. This paper is concerned with the identification and development of efficient and flexible methods of mapping logical traffic and control channels onto physical channels at the air interface for future multi-rate CDMA systems. We also address how a GSM 900/DCS 1800 fixed network may be evolved to support such systems.
