Center node: "wyner s network on caches combining receiver caching with a flexible backhaul"
  Abstract: In this work, we study a large linear interference network with an equal number of transmitters and receivers, where each transmitter is connected to two subsequent receivers. Each transmitter has individual access to a backhaul link (fetching the equivalent of $M_{T}$ files), while each receiver can cache a fraction $\gamma$ of the library. We explore the tradeoff between the communication rate, backhaul load, and caching storage by designing algorithms that can harness the benefits of cooperative transmission in partially connected networks, while exploiting the advantages of multicast transmissions attributed to user caching. We show that receiver caching and fetching content from the backhaul are two resources that can simultaneously increase the delivery performance in synergistic ways. #R##N#Specifically, an interesting outcome of this work is that user caching of a fraction $\gamma$ of the library can increase the per-user Degrees of Freedom (puDoF) by $\gamma$. Further, the results reveal significant savings in the backhaul load, even in the small cache size region. For example, the puDoF achieved using the pair $(M_{T}=8, #R##N#\gamma=0)$ can also be achieved with the pairs $(M_{T}=4,\gamma=0.035)$ and $(M_{T}=2,\gamma=0.1)$, showing that even small caches can provide significant savings in the backhaul load.
