Joint Beamformer Design for Wireless Fronthaul and Access Links in C-RANs
IEEE Transactions on Wireless Communications, 2018This paper presents a joint design framework of fronthaul and access links in cloud radio access networks, wherein the fronthaul data delivery between the central processor (CP) and small-cell base stations (SBSs) is carried over wireless links, which is more cost effective and flexible than the conventional wired fronthaul solutions. In this framework,

Joint Design of Fronthaul and Access Links for C-RAN With Wireless Fronthauling
IEEE Signal Processing Letters, 2016This letter studies a joint design of fronthaul and radio access links for a cloud radio access network (C-RAN) with wireless fronthauling, where a baseband unit (BBU) controls a number of remote radio heads (RRHs) via wireless fronthaul links to communicate with user equipments.

Diversity coded 5G fronthaul wireless networks
2017 Wireless Telecommunications Symposium (WTS), 2017In this paper we study the application of Diversity Coding to enable near-instantaneous recovery from link failures in 5G wireless Cloud Radio Access Network (C-RAN) networks. We focus on networks where remote radio heads in a C-RAN are connected to the baseband unit in two hierarchical tiers with optical and wireless fronthaul links. In order to avoid

Dynamic Distributed Antenna Systems with Wireless mmWave Fronthaul
2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019Cloud radio access network (CRAN) architectures promise improved scalability of mobile networks, both in terms of network capacity as well as capital expenditure for mobile network operators. Yet, the transition towards CRAN with fully virtualized base band units (BBUs) implemented in the cloud is a significant investment for network operators, since ...

An Efficient Wireless Fronthaul (EWF) Method for LTE Signal Transmission
2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017This paper proposes a novel EWF method for LTE signal transmission. Unlike the classical common public radio interface (CPRI) where the in-phase and quadrature (I/Q) waveforms and the control words (CWs) are transmitted as a binary sequence in the time domain, the proposed scheme transmits the analog I/Q waveforms and quadrature amplitude modulation ...

Compressed cooperative reception for the uplink of C-RAN with wireless fronthaul
2017 International Symposium on Wireless Communication Systems (ISWCS), 2017This work deals with a joint design of radio access and fronthaul links for the uplink of cloud radio access network (C-RAN) equipped with wireless fronthaul link. A conventional uplink system based on per-cell decode-and-forward (DF) relaying, in which the message sent by each user equipment (UE) is decoded by the closest remote radio head (RRH) and ...
