Random Linear Network Coding for 5G Mobile Video Delivery

An exponential increase in mobile video delivery will continue with the demand for higher resolution, multi-view and large-scale multicast video services. Novel fifth generation (5G) 3GPP New Radio (NR) standard will bring a number of new opportunities for optimizing video delivery across both 5G core and radio access networks. One of the promising approaches for video quality adaptation, throughput enhancement and erasure protection is the use of packet-level random linear network coding (RLNC). In this review paper, we discuss the integration of RLNC into the 5G NR standard, building upon the ideas and opportunities identified in 4G LTE. We explicitly identify and discuss in detail novel 5G NR features that provide support for RLNC-based video delivery in 5G, thus pointing out to the promising avenues for future research.Comment: Invited paper for Special Issue "Network and Rateless Coding for Video Streaming" - MDPI Informatio

Video Delivery in Dense 5G Cellular Networks

One of the main challenges for mobile network operators today is the efficient delivery of mobile VoD services. In order to satisfy their requirements, we must revolutionize the way we manage the densely deployed resources in 5G wireless networks, and tailor their operation for video content delivery. Two key approaches that leverage the density of the 5G infrastructure are the systematic usage of in-network storage resources available in BSs for the deployment of smart caching policies, and the video delivery optimization techniques that leverage the novel multi-tier, dense, and heterogeneous structure of 5G systems. We first provide an overview of the main features of the densely deployed 5G networks that are expected to shape mobile VoD services. Next, we present specific solutions that have recently been proposed for each one of the approaches above, and discuss the main lessons learned. Finally, we discuss a number of open problems for video delivery in dense 5G systems. © 1986-2012 IEEE
