Joint Power Control and Fronthaul Rate Allocation for Throughput Maximization in OFDMA-based Cloud Radio Access Network [PDF]

IEEE Transactions on Communications, 2015
The performance of cloud radio access network (C-RAN) is constrained by the limited fronthaul link capacity under future heavy data traffic. To tackle this problem, extensive efforts have been devoted to design efficient signal quantization/compression ...

5G New Radio Fronthaul Network Design for eCPRI-IEEE 802.1CM and Extreme Latency Percentiles

IEEE Access, 2019
Packet-switched fronthaul networks are often designed following the rule that the worst-case network delay must be below a given target end-to-end network latency budget.

Scheduling in an Ethernet fronthaul network [PDF]

2017 European Conference on Networks and Communications (EuCNC), 2017
This paper investigates and compares the performance of different scheduling techniques in an Ethernet fronthaul network in the presence of both time-sensitive/high priority and background traffic streams. A switched Ethernet architecture is used as the fronthaul section of a cloud radio access network (C-RAN) and a comparison of two scheduling schemes,

Transport Network Design for FrontHaul [PDF]

2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017
The evolution of LTE and advent of 5G networks increases further the bandwidth requirements for RAN. In parallel, the deployment of Centralized RAN architecture raises new challenges on the FrontHaul network. The inflexibility of the legacy CPRI is the primary challenge to Virtualized RAN deployments, and there is currently a strong trend towards the ...
