ZTE Develops Cloud Radio Scheduling/Coordination Functions for LTE

ZTE is showcasing a new Cloud Radio Solution for 4G network optimization at the Mobile Asia Expo conference in Shanghai. China Mobile is already testing ZTE’s Cloud Radio Solution to optimize trial TD-LTE networks in Guangzhou.

ZTE's Cloud Radio features newly developed Cloud Scheduling and Cloud Coordination modules for LTE network operators.

ZTE’s Cloud Scheduling module utilizes a central scheduler to manage network resources on a real-time basis and achieve unified network scheduling. The Cloud Coordination module enables seamless and borderless coordination for the whole network to improve user experience. Cloud Scheduling realizes coordination at the cell level from a macro perspective, while Cloud Coordination realizes coordination at the user level from a micro perspective. The two-level coordination helps operators build smooth LTE networks.

The company said its Cloud Radio solution will prove most use for mitigating signal interference issues at the cell edge. multiple-layer coordination within bases stations and network users, the approach should lead to a better user experience.

In April 2013, ZTE and China Mobile conducted the Phase I Cloud Radio Solution verification in a project site in Guangzhou. When the Cloud Scheduling function was enabled with the network at more than 70% loading, the data throughput volume of cell edge users increased by 40%. When the Cloud Coordination function was enabled, the throughput volume increased between 20% and 100%, with the improvement most pronounced for cell edge users. The test by ZTE and China Mobile was the first site-level verification of LTE-Advanced coordination technology in the global telecommunications industry.

China Mobile has now expanded the scale of the test in order to collect more performance data. In June 2013, ZTE and China Mobile started the Phase II large-scale Cloud Radio verification in the Tianhe commercial area of Guangzhou, a complex wireless environment with a variety of data transmission requirements.
