Interference Management for Millimeter-wave Mesh Backhaul Networks

Recently, since mobile traffic increases rapidly, SG network is required to support enhanced mobile broadband (eMBB) communications. Self-backhauling mmWave overlay heterogeneous network is proposed to realize eMBB at low cost. However, intra-channel interferences among mmWave backhaul links become an issue. This work proposes solutions to this problem through several approaches including proper deployment of mmWave access point, orthogonal channel allocation when necessary, and finally optimal power transmission allocation for alleviating bottleneck of the mesh backhaul networks. Ray-tracing based simulation result shows that the proposed algorithm can cope with bottleneck of the backhaul networks through the effects of the employed interference management schemes.
