Content-Based User Association and MIMO Operation over Cached Cloud-RAN Networks

  title={Content-Based User Association and MIMO Operation over Cached Cloud-RAN Networks},
  author={Susanna Mosleh and Lingjia Liu and Jonathan D. Ashdown and Erik S. Perrins and Kurt A. Turck},
Cloud radio access network (Cloud-RAN) has been introduced to support ever-growing end-users' needs. To reduce the backhaul traffic and aid coordinated multi-point (CoMP) transmission, base station (BS)-level caching technique can be utilized, where popular contents are pre-fetched at each BS. In this paper, multiple-input-multiple-output (MIMO) operation and user association policy are linked to the underlying cache placement strategy to ensure a good trade-off between load balancing and…

Joint data assignment and beamforming for backhaul limited caching networks

Low-complexity algorithms are proposed to solve the joint optimization problem, which essentially decouple the data assignment and the transmit power minimization beamforming of the cooperative wireless caching network.

Cache-aware user association in backhaul-constrained small cell networks
