QoS-Aware Resource Management for Converged Fiber Wireless 5G Fronthaul Networks [PDF]

2018 IEEE Global Communications Conference (GLOBECOM), 2018
The upcoming generation of mobile networks is expected to serve numerous mobile users with high quality-ofservice (QoS) demands, requiring high-capacity fronthaul. As the provision of fiber connections directly to the end users is not cost-efficient, the integrated fiber wireless (FiWi) fronthaul design based on wireless networking and passive optical ...

Boosting Fronthaul Capacity: Global Optimization of Power Sharing for Centralized Radio Access Network

, 2018
The limited fronthaul capacity imposes a challenge on the uplink of centralized radio access network (C-RAN). We propose to boost the fronthaul capacity of massive multiple-input multiple-output (MIMO) aided C-RAN by globally optimizing the power sharing
