Cloud Radio Access Network (C-RAN) enhances the utilization of computing and radio resources by concentrating Baseband Unit (BBU) at a data center. It is essential to find a flexible way to manage the computing resource since processing power has become the majority of system power in C-RAN. The computing resource demand of users can be scaled according to the modulation bits and other parameters...
Cell coverage and network capacity are two major challenges for the evolving 4G cellular wireless communication networks. Hierarchical layering of cells with macro base stations coexisting with low-power base stations in a service area has been investigated as a promising technique for enhancing the coverage extension and reducing the transmit power consumption, which has emerged as a candidate for...
Hierarchical layering of cells with macrocells coexisting with low-power small cells has been investigated as a promising technique to enhance coverage extension and reduce power consumption, which has emerged as a candidate for green communications. Due to the challenging interference scenarios, Cell Range Extension (CRE) and enhanced inter-cell interference coordination (eICIC) are the key technologies...
