Enabling Flexible Link Capacity for eCPRI-Based Fronthaul With Load-Adaptive Quantization Resolution

IEEE Access, 2019
Bandwidth-efficient 5G optical fronthaul interfaces, such as the Ethernet-based common public radio interface (eCPRI), with novel low layer split (LLS) are being actively investigated.

Real‐time demonstration of photonics‐based THz wireless fronthaul integrated with fiber‐optic mobile fronthaul

Microwave and Optical Technology Letters
AbstractA photonics‐based terahertz (THz) wireless fronthaul is proposed, and its feasibility is investigated by real‐time demonstration. The proposed wireless fronthaul can be simply integrated into existing fiber‐optic fronthaul, to serve as a complementary or emergency network.

Broadband linearization for 5G fronthaul transmission

Frontiers of Optoelectronics, 2018
5G is emerging, but the current fronthaul transmission technologies used for 3G and 4G may not be efficient and appropriate for 5G. It has been found that frequency division multiple access (FDMA) and time-division multiple access (TDMA) based radio over fiber (RoF) may be considered the most appropriate for 5G fronthaul transmission technology.

Enhanced Fronthaul Capacity in CRANs: Sum-Rate Maximization via Joint Optimal Design of STAR-RIS, Massive MIMO and Data Compression

IEEE Open Journal of Vehicular Technology
Cloud Radio Access Networks (CRAN) face a critical challenge due to the limited capacity of fronthaul links overwhelmed by massive data transmissions. This paper proposes a novel CRAN design that effectively tackles this challenge.
