Enabling Flexible Link Capacity for eCPRI-Based Fronthaul with Load-Adaptive Quantization Resolution
2019
IEEE Access
Preserved Fulltext
To tackle this issue, we propose a load-adaptive quantization resolution scheme that enables elastic fronthaul capacity. ...
Specifically, a full resolution is applied during low-load period, while for high-load case, to boost the link capacity, a stringent resolution is performed by removing the least significant quantization ...
CONCLUSION In this paper, we propose and demonstrate the load-adaptive flexible quantization resolution to achieve the eCPRI-based elastic fronthaul. ...

However, the transport link between the remote radio unit (RRU) and the baseband unit (BBU), known as fronthaul (FH), imposes stringent requirements in terms of data rate, latency, jitter, and synchronization ...
In the conventional C-RAN, the FH capacity scales linearly with the number of the transmitting antennas, which has posed severe demands on the FH capacity, especially due to emerging 5G technologies such ...
