Center node: "adaptive coded caching for fair delivery over fading channels"
  Abstract: The performance of existing \emph{coded caching} schemes is sensitive to the worst channel quality, a problem which is exacerbated when communicating over fading channels. In this paper, we address this limitation in the following manner: \emph{in short-term}, we allow transmissions to subsets of users with good channel quality, avoiding users with fades, while \emph{in long-term} we ensure fairness among users. Our online scheme combines the classical decentralized coded caching scheme \cite{maddah2013decentralized} with (i) joint scheduling and power control for the fading broadcast channel, as well as (ii) congestion control for ensuring the optimal long-term average performance. We prove that our online delivery scheme maximizes the alpha-fair utility among all schemes restricted to decentralized placement. By tuning the value of alpha, the proposed scheme enables to balance between different operating points on the average delivery rate region. We demonstrate via simulations that our scheme outperforms two baseline schemes: (a) standard coded caching with multicast transmission, limited by the worst channel user yet exploiting the global caching gain; (b) opportunistic scheduling with unicast transmissions exploiting only the local caching gain.
