In this paper, we propose a centralized allocation and scheduling strategy for 3-dimensional radio resources (namely, time, frequency, and power) for a multi-tier control-plane and user-plane (C-/U-plane) split 5G mobile network architecture by considering schedulers of all base stations (BSs) located at a central station. We consider a multi-tier network comprises of a macrocell BS (MCBS) and a number of outdoor picocell BSs as well as indoor femtocell BSs (FCBSs) deployed within a multi-storage building. In contrast to the conventional almost blank subframe, we consider a fully blank subframe (FBS) based eICIC to split completely C-/U-plane such that control-plane can be served only by the MCBS and user-plane by each UE’s respective BS. The system bandwidth is reused in FCBSs, and frequency resources are allocated orthogonally per tier basis. We propose a simple FCBS power control mechanism by modeling a FCBS’s on-state and off-state power as on/off traffic source model, and derive an optimal value of average activation factor (AAF) of any FCBSs per FBS pattern period to trade-off its serving capacity and transmit power saving. With a system level simulation it is shown that the capacity of a FCBS increases whereas its power saving decreases linearly with an increase in its AAF because of serving increased traffic, and an optimal AAF of 0.5 for the capacity scaling factor k=1and greater than 0.5 for k<1is found.
