Joint Multicast and Unicast Beamforming for Coded Caching

In this paper, we consider a multicell system with cache-equipped base stations (BSs) and users. A coded caching scheme is employed at user ends such that multiple requested file contents can be combined and encoded together at the BS, and decoded successfully at the users. The BSs can then multicas...
