Coded Caching Under Heterogeneous User Preferences: An Effective Throughput Perspective

Proactive caching is a promising means to handle increasing wireless traffic. However, how heterogeneous user preferences impact the caching gain is still an open problem. In this paper, a two-phase cache-aided multicasting network is investigated, in which users with heterogeneous preferences are served by a base station through a shared link. It is shown that the achievable domain of effective throughput of the users is a convex set and can be...
