Collaborative Multicast Beamforming for Content Delivery by Cache-Enabled Ultra Dense Networks

Caching and multicast have surged as effective tools to alleviate the heavy load from the backhaul links while enabling content-centric delivery in communication networks. The main focus of work in this area has been on the cache placements to manage the network delay and backhaul transmission cost....
