Content delivery with coded caching and massive MIMO in 5G

Abstract : Do the gains from massive MIMO and coded caching cumulate? In this paper, we try to answer the question in a simple setting of downlink MIMO channel with Rayleigh quasi-static fading. While it is generally perceived that each of massive MIMO and coded caching is scalable alone with the number of users, we show that in this setting MIMO and coded caching are indeed complementary and the combination of both provides a scalable solution in most practical scenarios.
