MultiCode-CDMA is a good choice for wireless networking because it can support devices with different peak transmission rates within one network and hence, enables cost scalability. However, delivering delay guarantee in a MultiCode-CDMA network is difficult because its capacity is variable even in a perfect wireless channel. In this paper, we develop a scheme called MultiCode-DRR as a solution to the problem. The basic idea of MultiCode-DRR is to separate the variable capacity into a deterministic component and a variable component, and to use these components to serve time-sensitive traffic and non-time-sensitive traffic, respectively. Simulation results confirm that the maximum time-sensitive packet delay never exceeds the theoretical upper bound when the devices are served using the proposed scheme. In short, MultiCode-DRR is significant because it enables a MultiCode-CDMA network to deliver deterministic upper delay guarantee.
