In this paper, a Frequency Division Duplex (FDD) wideband Code Division Multiple Access (CDMA) Medium Access Control (MAC) protocol is developed for wireless wide area multimedia networks. In order to reach the maximum system capacity and guarantee the heterogeneous Bit Error Rates (BERs) of multimedia traffic, a minimum-power allocation algorithm is first derived, where both MultiCode (MC) and Orthogonal Variable Spreading Factor (OVSF) transmissions are assumed. Based on the minimum-power allocation algorithm, a multimedia wideband CDMA Generalized Processor Sharing (GPS) scheduling scheme is proposed. It provides fair queuing to multimedia traffic with different QoS constraints.
