service from a low power basestation in the presence of macro base-stations with stronger …

… level, energy consumption can be reduced by controlling network cell size and their layouts
[21]. Heterogeneous networks are supposed to conserve energy if the distance between …

… exploit the heterogeneous networks (HetNets), where traditional macro base stations (MBSs…

… In this paper we have considered the downlink joint base station assignment and beamforming
problem for a wireless heterogeneous network, with the goal of maximizing a system …

… cellular networks with QoS constraints. We first derive the upper and lower bounds of the …
and, based on these, we analyze the optimal BS density for heterogeneous networks. The …
