Calibration algorithm for C-RAN BBU-RRH switching schemes
2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC), 2016In face of the rapid growth of data traffic in cellular networks, Cloud Radio Access Network (C-RAN) architecture has been proposed as a solution to obtain better performance in terms of efficiency, expansibility, elasticity, stability and expenditure such as Capital Expenditure (CAPEX) and Operational Expenditure (OPEX).

RRH clustering in cloud radio access networks with re-association consideration
2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018 Cloud Radio Access Network (C-RAN) is an evolution in the base station architecture, mainly composed of two elements: The Base Band Unit (BBU) and the Remote Radio Head (RRH). This new architecture separates the two elements (the BBUs from RRHs), to group all the BBUs into one cloud, while RRHs are distributed across many sites.

Interference Control Based on Beamforming Coordination for Heterogeneous Network With RRH Deployment
IEEE Systems Journal, 2015In this paper, we focus on heterogeneous networks (HetNet) where low-power remote radio head (RRH) nodes are deployed within the coverage area of an existing macro network, aiming at offloading traffic from the macro cell to small cells. To improve the data rate both for users served by macro base stations (BSs) and those by RRH nodes, this paper ...

BBU-RRH switching schemes for centralized RAN
7th International Conference on Communications and Networking in China, 2012Mobile data traffic has been increasing at a rapid pace over the past few years due to the rise of both smartphones and tablets. Small cell deployments are one of the most effective ways to increase system capacity by improving the spatial reuse of radio resources for the explosive increase in traffic loads.
