Downlink Transmission and Caching Strategies for Backhaul-Limited Cloud Radio Access Networks
This thesis considers a downlink cloud radio access network (C-RAN) where all the base stations (BSs) are connected to a central processor (CP) via capacity-limited backhaul links. Two fundamental and different downlink transmission strategies are studied, namely the data-sharing strategy and the …
