Efficient Transport of eCPRI Fronthaul over PON

2023 Optical Fiber Communications Conference and Exhibition (OFC), 2023
Passive optical networks (PONs) facilitate small cell deployments. Back- and midhaul already make efficient use of PON. We explain the steps taken in mobile and in PON industries to enable efficient eCPRI fronthaul over PON.

Research and Implementation of eCPRI Processing Module for Fronthaul Network on FPGA in 5G – NR gNodeB Base Station

2020 4th International Conference on Recent Advances in Signal Processing, Telecommunications & Computing (SigTelCom), 2020
Fronthaul is associated with a new and different type of Radio Access Network architecture consisting of centralized Baseband Units (BBUs) and Remote Radio Units (RRUs) [2] . In order to meet the fifth-generation wireless (5G) challenges of increased traffic and data flows, a new connection protocol for the fronthaul network called Evolved Common ...

Quantization-Noise Suppression for Uplink eCPRI Assisted by Wireless-Channel Estimation Feedback

2018 European Conference on Optical Communication (ECOC), 2018
The behavior of quantization-noise in uplink eCPRI under the influence of wireless-channel fading is theoretically analyzed. And a noise-suppression method based on low-complexity DSP is demonstrated by standard-channel modeling and experimental transmission, which can reduce 6.5-dB noise power.

400Gb/s Real-time Transmission Supporting CPRI and eCPRI Traffic for Hybrid LTE-5G Networks

Optical Fiber Communication Conference Postdeadline Papers 2020, 2020
We present the first CMOS ASIC to support either 4x25Gb/s eCPRI or 4x24.33Gb/s CPRI-10 traffic per optical wavelength and demonstrate 200Gb/s and 400Gb/s transmissions in O and C bands over 20km for hybrid LTE-5G fronthaul networks.

A pragmatic industrial road map for shifting the existing fronthaul from CPRI to 5G compatible eCPRI

2020 IEEE 3rd 5G World Forum (5GWF), 2020
In this fast approaching era of 5G deployments, MNOs have started implementing Centralized radio access networks (C-RAN) so that it can fulfil the prodigious requirements of future 5G services in terms of network latency, service availability, capacity, and network coordination.

OTA enabled 147.4 Gb/s eCPRI-equivalent-rate radio-over-fiber link cooperating with mmWave-based Korea Telecom 5G mobile network for distributed antenna system

Optical Fiber Communication Conference Postdeadline Papers 2019, 2019
We demonstrate an over-the-air (OTA) based 4×4 MIMO distributed antenna system with a radio-over-fiber that provides 147.4-Gb/s eCPRI-equivalent-rate, achieving ∼4 Gb/s data throughput per cell in conjunction with Korea Telecom 5G mobile network employing mmWave.
