Network Slicing-Enabled Green C-RAN
Network slicing is an emerging technology that allows mobile network operators (MNOs) to slice their physical networks into logical ones, thereby providing independent services to multiple mobile virtual network operators (MVNOs). With the incorporation of network slicing, physical network resources can be allocated in terms of network slices, each of which represents a virtualized and isolated network with reserved network resources.
Cloud radio access network (C-RAN) incorporates the concept of cloud computing into RANs, which generally consists of a baseband unit (BBU) pool and remote radio heads (RRHs). The BBU pool is located at a centralized site with abundant computing resources, while the RRHs are distributed antenna units that are deployed apart from the BBU pool. By pooling the BBUs of RRHs together, lower capital and operation expenditures (CapEx and OpEx) for MNOs can be envisaged.
Remote radio head(RRH) is a set of...
