A generalized processor sharing approach to time scheduling in hybrid CDMA/TDMA

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. In our previous works, we proposed the hybrid CDMA/TDMA technique as an appropriate multiple access control (MAC) scheme for wireless ATM networks. We also investigated the problem of power control in such hybrid systems. In this paper, we continue our study and address the time scheduling issue of hybrid CDMA/TDMA. Using the generalized processor sharing technique, typically employed in TDMA systems, we develop a time scheduling scheme suitable for the class of hybrid CDMA/TDMA systems. We also study the implementation of this scheme in a specific hybrid system we proposed earlier and address its integration with our power control technique
