Load diversity based processing resource allocation for super base stations in large-scale centralized radio access networks

In order to reduce high construction cost and energy consumption of distributed base stations in cellular networks, the centralized radio access Cellular network infrastructure with a Super BS(CSBS) architecture has been proposed in which the centralized processing resource can be flexibly organized. However, there is sill the problem of low processing resource efficiency in protocol processing. In this paper, based on a protocol processing resource management framework, distributed load diversity based processing resource allocation (D-LDA) as well as the improved hybrid load diversity based processing resource allocation(H-LDA) are proposed, which take load discrepancy into consideration in the situation that a large number of BSs are supported. Simulation results show that D-LDA and H-LDA algorithm significantly outperforms the conventional method respectively by more than 30% and 55% in the processing resource efficiency.
