Robust Beamforming for Cache-Enabled Cloud Radio Access Networks [PDF]

2018 IEEE Globecom Workshops (GC Wkshps), 2018
Popular content caching is expected to play a major role in efficiently reducing backhaul congestion and achieving user satisfaction in next generation mobile radio systems. Consider the downlink of a cache-enabled cloud radio access network (CRAN), where each cache-enabled base station (BS) is equipped with limited-size local cache storage.

A new network slicing framework for multi-tenant heterogeneous cloud radio access networks [PDF]

, 2016
Research on network slicing for multi-tenant heterogeneous cloud radio access networks (H-CRANs) is still in its infancy. In this paper, we redefine network slicing and propose a new network slicing framework for multi-tenant H-CRANs.
