Ultra-Reliable Cloud Mobile Computing with Service Composition and Superposition Coding
Seyyed Mohammadreza Azimi, Osvaldo Simeone, Onur Sahin +1
An emerging requirement for 5G systems is the ability to provide wireless ultra-reliable communication (URC) services with close-to-full availability for cloud-based applications.…
Cloud Radio Access Network: Virtualizing Wireless Access for Dense Heterogeneous Systems
Osvaldo Simeone, Andreas Maeder, Mugen Peng +2
Cloud Radio Access Network (C-RAN) refers to the virtualization of base station functionalities by means of cloud computing. This results in a novel cellular architecture in which…
Joint Interference Alignment and Bi-Directional Scheduling for MIMO Two-Way Multi-Link Networks
A. M. Fouladgar, O. Simeone, O. Sahin +2
By means of the emerging technique of dynamic Time Division Duplex (TDD), the switching point between uplink and downlink transmissions can be optimized across a multi-cell system…
Signal and Interference Leakage Minimization in MIMO Uplink-Downlink Cellular Networks
Tariq Elkourdi, Osvaldo Simeone, Onur Sahin +1
Linear processing in the spatial domain at the base stations (BSs) and at the users of MIMO cellular systems enables the control of both inter-cell and intra-cell interference. A n…
Multihop Backhaul Compression for the Uplink of Cloud Radio Access Networks
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
In cloud radio access networks (C-RANs), the baseband processing of the radio units (RUs) is migrated to remote control units (CUs). This is made possible by a network of backhaul…
Performance Evaluation of Multiterminal Backhaul Compression for Cloud Radio Access Networks
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
In cloud radio access networks (C-RANs), the baseband processing of the available macro- or pico/femto-base stations (BSs) is migrated to control units, each of which manages a sub…
Multi-Layer Transmission and Hybrid Relaying for Relay Channels with Multiple Out-of-Band Relays
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
In this work, a relay channel is studied in which a source encoder communicates with a destination decoder through a number of out-of-band relays that are connected to the decoder…
Joint Precoding and Multivariate Backhaul Compression for the Downlink of Cloud Radio Access Networks
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
This work studies the joint design of precoding and backhaul compression strategies for the downlink of cloud radio access networks. In these systems, a central encoder is connecte…
Multi-Layer Hybrid-ARQ for an Out-of-Band Relay Channel
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
This paper addresses robust communication on a fading relay channel in which the relay is connected to the decoder via an out-of-band digital link of limited capacity. Both the sou…
Robust and Efficient Distributed Compression for Cloud Radio Access Networks
Seok-Hwan Park, Osvaldo Simeone, Onur Sahin +1
This work studies distributed compression for the uplink of a cloud radio access network where multiple multi-antenna base stations (BSs) are connected to a central unit, also refe…
Interference Channel with an Out-of-Band Relay
Onur Sahin, Osvaldo Simeone, Elza Erkip
A Gaussian interference channel (IC) with a relay is considered. The relay is assumed to operate over an orthogonal band with respect to the underlying IC, and the overall system i…
Interference Channel with a Half-Duplex Out-of-Band Relay
Onur Sahin, Osvaldo Simeone, Elza Erkip
A Gaussian interference channel (IC) aided by a half-duplex relay is considered, in which the relay receives and transmits in an orthogonal band with respect to the IC. The system…
