… and RAT assignment in a multi-radio heterogeneous network. … is carried out for RAT
assignments on a per small cell basis. … Section III presents RAT assignment techniques for small …

… network structure, heterogeneous network (HetNet) has been studied in recent years. Compared
with homogeneous networks, … the definition and different network scenarios of HetNets. …

… Our solution to this problem is to assign orthogonal pilots to a part of SUs. Consequently,
the MBS can estimate the crossCSI to suppress the cross-tier interference, while cross-tier …
