The traditional layered approach to wireless networks (network, data link, and physical layer) utilizes suboptimally the limited available capacity. We propose a Quality of Service wireless framework based on the joint design of a packet fair queuing scheduler, demand-assignment Medium Access Control (MAC) protocol, and Multirate Multipath-Transparent CDMA-based physical layer. The unique code assignment procedure allows a direct mapping of the packet fair schedule to the physical layer transmission/reception, and supports transmission (service) rates of arbitrarily fine resolution. Judiciously designed user codes combat the harsh time. varying fading environment, and parsimonious code description minimizes overhead in the MAC. Simulations illustrate the merits of our designs.
