English abstract:
Cloud radio access network (CRAN) architectures promise improved scalability of future mobile networks, both in terms of network capacity as well as capital expenditure for mobile network operators. Yet, the transition towards CRAN with fully virtualized base band units (BBUs) implemented in the cloud is no minor step for network
operators, since most of the existing base band processing hardware in already deployed macro base stations (BSs) becomes outdated. A gradual transition towards CRAN can be facilitated by initially reusing existing BBUs in macro BSs and augmenting them with additional remote radio units (RRUs), which are spatially distributed in the network
coverage area and can be freely associated to any macro BS over a reconfigurable front-haul network. In this paper, we consider optimal allocation of RRUs amongst BBUs, which are implemented in existing macro BSs. We assume that the network of macro BSs provides a basic coverage layer by implementing the control-plane of the mobile network (e.g. at low GHz), whereas RRUs provide on-demand network capacity through the user-plane (e.g. in the millimeter wave band).
