Improved Converses and Gap Results for Coded Caching
Chien-Yi Wang, Shirin Saeedi Bidokhti, Michele Wigger
Improved lower bounds on the average and the worst-case rate-memory tradeoffs for the Maddah-Ali&Niesen coded caching scenario are presented. For any number of users and files and…
On Achievability for Downlink Cloud Radio Access Networks with Base Station Cooperation
Chien-Yi Wang, Michèle Wigger, Abdellatif Zaidi
This work investigates the downlink of a cloud radio access network (C-RAN) in which a central processor communicates with two mobile users through two base stations (BSs). The BSs…
Information Theoretic Caching: The Multi-User Case
Sung Hoon Lim, Chien-Yi Wang, Michael Gastpar
In this paper, we consider a cache aided network in which each user is assumed to have individual caches, while upon users' requests, an update message is sent though a common link…
A New Converse Bound for Coded Caching
Chien-Yi Wang, Sung Hoon Lim, Michael Gastpar
An information-theoretic lower bound is developed for the caching system studied by Maddah-Ali and Niesen. By comparing the proposed lower bound with the decentralized coded cachin…
Information-Theoretic Caching: Sequential Coding for Computing
Chien-Yi Wang, Sung Hoon Lim, Michael Gastpar
Under the paradigm of caching, partial data is delivered before the actual requests of users are known. In this paper, this problem is modeled as a canonical distributed source cod…
