Control-Data Separation with Decentralized Edge Control in Fog-Assisted Uplink Communications
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
Fog-aided network architectures for 5G systems encompass wireless edge nodes, referred to as remote radio systems (RRSs), as well as remote cloud center (RCC) processors, which are…
On the Trade-Off between Computational Load and Reliability for Network Function Virtualization
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang
Network Function Virtualization (NFV) enables the "softwarization" of network functions, which are implemented on virtual machines hosted on Commercial off-the-shelf (COTS) servers…
Cloud Radio Access Networks: Uplink Channel Estimation and Downlink Precoding
Osvaldo Simeone, Jinkyu Kang, Joonhyuk Kang +1
The gains afforded by cloud radio access network (C-RAN) in terms of savings in capital and operating expenses, flexibility, interference management and network densification rely…
Control-Data Separation across Edge and Cloud for Uplink Communications in C-RAN
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
Fronthaul limitations in terms of capacity and latency motivate the growing interest in the wireless industry for the study of alternative functional splits between cloud and edge…
Layered Downlink Precoding for C-RAN Systems with Full Dimensional MIMO
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
The implementation of a Cloud Radio Access Network (C-RAN) with Full Dimensional (FD)-MIMO is faced with the challenge of controlling the fronthaul overhead for the transmission of…
Fronthaul Compression and Precoding Design for C-RANs over Ergodic Fading Channel
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
This work investigates the joint design of fronthaul compression and precoding for the downlink of Cloud Radio Access Networks (C-RANs). In a C-RAN, a central unit (CU) performs th…
Joint Signal and Channel State Information Compression for the Backhaul of Uplink Network MIMO Systems
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
In network MIMO cellular systems, subsets of base stations (BSs), or remote radio heads, are connected via backhaul links to central units (CUs) that perform joint encoding in the…
