Preface
With the 4G cellular networks reaching saturation, the 5G networks have recently
attracted growing attention and research efforts in both academic and industry
communities. The 5G cellular networks are featured as very-high-density base
stationsandwirelessdevicesandintegrationofheterogeneousnetworks.Asaresult,
advanced interference management schemes are critical for achieving the desired
network throughput. Due to the high density of wireless devices, users located in
thecellboundaryareaprobablysharethesamechannelresourceswithotherusersin
thesameareaassociatedwithneighboringcells,therebycausingsevereinterference
to each other. In addition, the heterogeneous networks will add complexity in
dealing with the mutual interference. This Springer Brief presents interference
coordinationtechniquesforfuture5Gcellularnetworks.Startingwithanoverview
of existing interference management techniques, this Brief focuses on practical
interferencecoordinationschemesbasedonbeamforminganduserscheduling.The
proposed schemes aim to deal with the intercell interference in multicell MIMO
networks, cross-tier interference in device-to-device communications underlaying
cellular networks, and inter-network interference in cognitive radio networks.
The performances of the proposed schemes are evaluated both analytically and
numerically in terms of several performance parameters, including the sum rate,
multiplexinggain,andoutageprobabilityofthenetworks.Theresultsshowthatthe
proposed schemes can significantly reduce the effect of interference and improve
thequalityofserviceofthenetworks.
