The fifth generation (5G) wireless network technology is to be standardized by 2020, where
main goals are to improve capacity, reliability, and energy efficiency, while reducing latency …

Contrary to orthogonal multiple-access (OMA), non-orthogonal multiple-access (NOMA)
schemes can serve a pool of users without exploiting the scarce frequency or time domain …

This paper has the following ambitious goal: to convince the reader that content caching is
an exciting research topic for the future communication systems and networks. Caching has …

This paper studies the joint design of cloud and edge processing for the downlink of a fog
radio access network (F-RAN). In an F-RAN, as in cloud-RAN (C-RAN), a baseband …

We consider a system, comprising a library of N files (eg, movies) and a wireless network
with a KT transmitters, each equipped with a local cache of size of MT files and a KR …

Caching at mobile edge servers can smooth temporal traffic variability and reduce the
service load of base stations in mobile video delivery. However, the assignment of multiple …

In the context of coded caching in the K-user broadcast channel, our work reveals the
surprising fact that having multiple (L) transmitting antennas, dramatically ameliorates the …

A fog-aided wireless network architecture is studied in which edge nodes (ENs), such as
base stations, are connected to a cloud processor via dedicated fronthaul links while also …

The work explores the fundamental limits of coded caching in the setting where a transmitter
with potentially multiple (N 0) antennas serves different users that are assisted by a smaller …

This paper studies the fundamental tradeoff between storage and latency in a general
wireless interference network with caches equipped at all transmitters and receivers. The …
