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.

Exploiting Core-Switching to Minimize Fronthaul Degradation using Multicore Fiber
, 2018 Fronthaul connections carried by Multicore Fibers (MCFs) might experience different degradations if they are carried by different cores. This paper shows that switching fronthaul connections between the cores helps to minimizing the fronthaul service ...

QR Approximation for Massive MIMO Fronthaul Compression [PDF]
, 2019 Massive MIMO's immense potential to serve large number of users at fast data rates also comes with the caveat of requiring tremendous processing power. This favours a centralized radio access network (C-RAN) architecture that concentrates the processing ...

Pipelined Fronthaul-Edge Content Delivery in Fog Radio Access Networks
, 2016 In a Fog Radio Access Network (F-RAN), content delivery is carried out using both edge caching and cloud processing. A key design question for F-RANs hence concerns the optimal use of edge and cloud resources. In this work, this problem is addressed from

Optical Fronthaul Options for Meeting 5G Requirements [PDF]
, 2018 New functional splits for the 5G Radio Access Network have been identified so that fronthaul will no longer need to transport sampled time-domain waveforms. However, the different functional split points place differing demands on the fronthaul transport,
