Inter-BS Interference-Aware Transmission Coordination for Millimeter Wave Networks

In millimeter-wave wireless networks, base stations (BSs) are capable of performing beamforming transmissions to deliver downlink data packets to user equipments. Despite the advantage of spatial diversity (through beamforming), as the number of BSs installed in the network increases, the packet delivery success probability may decrease because of the increasing interference from the beamforming transmissions of neighboring BSs. We propose the downlink transmission coordination methods that allow each BS to decide whether or not to perform a downlink transmission with respect to the level of inter-BS interferences.
