Multi-Tenant C-RAN With Spectrum Pooling: Downlink Optimization Under Privacy Constraints
Seok-Hwan Park, Osvaldo Simeone, Shlomo Shamai
Spectrum pooling allows multiple operators, or tenants, to share the same frequency bands. This work studies the optimization of spectrum pooling for the downlink of a multi-tenant…
Coded Multicast Fronthauling and Edge Caching for Multi-Connectivity Transmission in Fog Radio Access Networks
Seok-Hwan Park, Osvaldo Simeone, Wonju Lee +1
This work studies the advantages of coded multicasting for the downlink of a Fog Radio Access Network (F-RAN) system equipped with a multicast fronthaul link. In this system, a con…
Fronthaul Quantization as Artificial Noise for Enhanced Secret Communication in C-RAN
Seok-Hwan Park, Osvaldo Simeone, Shlomo Shamai
This work considers the downlink of a cloud radio access network (C-RAN), in which a control unit (CU) encodes confidential messages, each of which is intended for a user equipment…
Joint Design of Digital and Analog Processing for Downlink C-RAN with Large-Scale Antenna Arrays
Jaein Kim, Seok-Hwan Park, Osvaldo Simeone +2
In millimeter-wave communication systems with large-scale antenna arrays, conventional digital beamforming may not be cost-effective. A promising solution is the implementation of…
