The virtualization of Radio Access Networks (RANs) has been proposed as one of the important use cases of Network Function Virtualization (NFV). In Virtualized Radio Access Networks (VRANs), some functions from a Base Station (BS), such as those which make up the Base Band Unit (BBU), may be implemented in a shared infrastructure located at either a data center or distributed in network nodes. For...
This paper addresses the problem of radio resource allocation in a multi-user broadcast downlink flat-fading channel, where the receiving nodes are considered to be battery-powered devices provided with energy harvesting sources. Models for the energy consumption of the RF and decoding stages are discussed and included explicitly in the design of the resource allocation strategy. The allocation is...
