This paper proposes a green Intelligent Traffic and Resource Elastic Energy (iTREE) scheme for C-RAN. In iTREE, BBUs are reduced by matching the right amount of baseband processing with traffic load.  ...  With such an arrangement, more energy gains can be acquired through statistical multiplexing by reducing the number of BBUs used.  ...  Jingchu et al. in [13] presents a mathematical model to quantify the statistical multiplexing gain of pooling VBS.  ...
