Spectrally efficient fronthaul architectures for a cost-effective 5G C-RAN

, 2016
In 5G wireless systems, centralized RAN (C-RAN) is an architectural choice where the signal waveforms received by Remote Radio Heads (RRH) are transparently forwarded to base band units (BBU), in many cases using an optical fronthaul.

Data Compression Scheme of Fronthaul Network Based on LTE

International Journal of Online and Biomedical Engineering (iJOE), 2018
As the long term evolution (LTE) mobile users and transmission data increase, the load of the fronthaul network increases. In order to control the consumption of optical fiber resources, and prevent congestion under the premise of increasing data transmission, it is necessary to compress the data of the fronthaul network.

SDN-based management of time-sensitive networks in 5G fronthaul

Software Defined Networking is a key element in the 5G architecture, as it allows a more flexible, dynamic network management. Cloud RAN is another enabler of 5G, due to the expected increased based station density in the fronthaul.

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

Streamlined Swift Allocation Strategies for Sequential Fronthaul Cell-Free Massive MIMO

IEEE Access
Centralized access point (AP) selection approaches in sequential fronthaul cell-free (SF-CF) networks, such as centralized maximum ratio combining (CMRC) or centralized optimal sequence linear processing (COSLP), often hinder its scalability by ...
