Abstract
Adaptive resource allocation arises naturally as a technique to optimize resource utilization in communication networks with scarce resources under dynamic conditions. One prominent example is cellular communication where service providers seek to utilize the costly resources in the most effective way. In this work, we investigate an uplink resource allocation scheme that takes into account the buffer occupation at the transmitter to retain a given level of quality of service (QoS). First, we regard exact results for the class of Poisson traffic where we investigate the sensitivity of the resource adaptation and QoS level to the actuating variables. We show relevant resource savings in comparison with a static allocation. Further, we regard a queueing setting with general random arrival and service processes. In particular, we consider the service of wireless fading channels. We show two different resource adaptation mechanisms that depend on the strictness of different assumptions. Finally, we present simulation results that show substantial resource savings using the queue-aware scheduling scheme, where we provide insight on the implementation and operation of such an adaptive system.
