Mobility-Sensitive Power Control for MBSFN Cellular Networks

Cellular networks´ Multimedia Broadcast/Multicast Service (MBMS) over a Single Frequency Network (MBSFN) allows broadcasting cell signals to constructively interfere and users to take advantage of increased bit rates compared to other broadcasting technologies. In this paper, we present our work on the optimization of the power control for future cellular networks that employ MBSFN transmission scheme. We propose a novel simulator and optimizer that can minimize the transmission power of individual cells taking into account the changing positions of users. In order to read descriptions of the various scenarios, the simulator uses the eXtendable Temporal Network Description Language (XTNDL), a language that is defined in this paper. The optimizer´s engine can be used in conjunction with the simulator or can be modified to read real time measurements from a real network.
