Coded Caching over Wireless: challenges and some solutions

Coded caching, a recent breakthrough proposed by Maddah-Ali and Niesen, has inspired a rethinking of wireless downlink channels. Although a substantial gain, in particular its scalability with respect to the number of users, is proved theoretically, several limitations hinder its applicability in practical systems. In this talk, we focus on the challenges mainly related to the content delivery phase over the practical downlink channel. To this end, we address the following questions:
- How to make a scalable content delivery based on coded caching?
- How to deal with fairness between users?
- How to deal with online delivery when users requests arrive and served continuously?
We provide solutions to each of these questions.
Mari Kobayashi received the B.E. degree in electrical engineering from Keio University, Yokohama, Japan, in 1999 and the M.S. degree in mobile radio and the Ph.D. degree from École Nationale Supérieure des Télécommunications, Paris, France, in 2000 and 2005, respectively. From November 2005 to March 2007, she was a postdoctoral researcher at the Centre Tecnològic de Telecomunicacions de Catalunya, Barcelona, Spain. In May 2007, she joined the Telecommunications department at CentraleSupélec, Gif-sur-Yvette, France, where she is now professor. She is the recipient of the Newcom++ Best Paper Award in 2010, the Joint Information Theory/Communications Society Best Paper Award in 2011. Since September 2017, she is visiting Institute for Communication Engineering, Technische Universität München as an Alexandar von Humboldt Research Fellow.
