With the development of diverse wireless communication technologies,interference has become a key impediment in network performance, thus makingeffective interference management (IM) essential to accommodate a rapidlyincreasing number of subscribers with diverse services. Although there havebeen numerous IM schemes proposed thus far, none of them are free of some formof cost. It is, therefore, important to balance the benefit brought by and costof each adopted IM scheme by adapting its operating parameters to variousnetwork deployments and dynamic channel conditions. We propose a novel IM scheme, called dynamic interference steering (DIS), byrecognizing the fact that interference can be not only suppressed or mitigatedbut also steered in a particular direction. Specifically, DIS exploits bothchannel state information (CSI) and the data contained in the interferingsignal to generate a signal that modifies the spatial feature of the originalinterference to partially or fully cancel the interference appearing at thevictim receiver. By intelligently determining the strength of the steeringsignal, DIS can steer the interference in an optimal direction to balance thetransmitter's power used for IS and the desired signal's transmission. DIS isshown via simulation to be able to make better use of the transmit power, henceenhancing users' spectral efficiency (SE) effectively.
