… Abstract— In ultra-dense networks (UDNs), the dense deployment of base stations (BSs) is
… In this paper, we tame traffic uncertainty for the joint optimization of BS activation and user …

… Therefore, it is important that we study the effect of BS activation on a CoMP-based ultra
dense network (CUDN). We also note that the conventional strategies are not completely …
