Rate-memory trade-off for multi-access coded caching with uncoded placement

KS Reddy, N Karamchandani - IEEE Transactions on …, 2020 - ieeexplore.ieee.org
We study a multi-access variant of the popular coded caching framework, which consists of a
central server with a catalog of N files, K caches with limited memory M, and K users such …

Coded caching with shared caches: Fundamental limits with uncoded prefetching

E Parrinello, A Ünsal, P Elia - arXiv preprint arXiv:1809.09422, 2018 - arxiv.org
The work identifies the fundamental limits of coded caching when the K receiving users
share {\Lambda} $\leq $ K helper-caches, each assisting an arbitrary number of different …

An improved multi-access coded caching with uncoded placement

S Sasi, BS Rajan - arXiv preprint arXiv:2009.05377, 2020 - arxiv.org
In this work, we consider a slight variant of well known coded caching problem, referred as
multi-access coded caching problem, where each user has access to $ z $ neighboring …

Fundamental limits of coded caching: Improved delivery rate-cache capacity tradeoff

MM Amiri, D Gündüz - IEEE Transactions on Communications, 2016 - ieeexplore.ieee.org
A centralized coded caching system, consisting of a server delivering N popular files, each
of size F bits, to K users through an error-free shared link, is considered. It is assumed that …

Coded caching with asymmetric cache sizes and link qualities: The two-user case

D Cao, D Zhang, P Chen, N Liu… - IEEE Transactions on …, 2019 - ieeexplore.ieee.org
The centralized coded caching problem is studied for the two-user scenario, considering
heterogeneous cache capacities at the users and private channels from the server to the …

Coded caching for a large number of users

MM Amiri, Q Yang, D Gündüz - 2016 IEEE Information Theory …, 2016 - ieeexplore.ieee.org
We consider the coded caching problem with a central server containing N files, each of
length F bits, and K users, each equipped with a cache of capacity MF bits. We assume that …

Optimization of heterogeneous coded caching

AM Daniel, W Yu - IEEE Transactions on Information Theory, 2019 - ieeexplore.ieee.org
This paper aims to provide an optimization framework for coded caching that accounts for
various heterogeneous aspects of practical systems. An optimization theoretic perspective …

Coded caching with heterogeneous cache sizes and link qualities: The two-user case

D Cao, D Zhang, P Chen, N Liu… - … on Information Theory …, 2018 - ieeexplore.ieee.org
The centralized coded caching problem is studied under heterogeneous cache sizes and
channel qualities from the server to the users, focusing on the two-user case. A server …

Closing the gap for coded caching with distinct file sizes

J Zhang, X Lin, CC Wang - 2019 IEEE International …, 2019 - ieeexplore.ieee.org
Coded caching can exploit multicast opportunities even when multiple users request
different pieces of content, and thus can significantly reduce the backhaul requirement to …

Coded caching for files with distinct file sizes

J Zhang, X Lin, CC Wang… - 2015 IEEE International …, 2015 - ieeexplore.ieee.org
Coded caching can exploit new multicast opportunities even when multiple users request
different pieces of content, and thus can significantly reduce the backhaul requirement for …
