CARES: Computation-Aware Scheduling in Virtualized Radio Access Networks

In a virtualized radio access network (RAN), baseband processing is performed by software running in cloud-computing platforms. However, current protocol stacks were not designed to run in this kind of environment; the high variability on the computational resources consumed by RAN functions may lead to eventual computational outages (where frames are not decoded on time), severely degrading the resulting performance. In this paper, we address...
