Abstract

Future wireless ATM networks are expected to support a variety of services with different bit-rates and quality-of-service (QoS) requirements. A major challenge for these networks is the design of the multiple access scheme. We introduce a new MAC protocol called scheduled CDMA (SCDMA). This scheme is a hybrid CDMA/TDMA scheme in which the base station schedules transmission of CDMA-based mobile terminals. At any time, a group of services are scheduled to transmit simultaneously. Interference control is done with power control. Several QoS issues of this scheme are addressed including power control, application of FEC coding, and high bit-rate service support
