Query: Dynamic Interference Steering in Heterogeneous Cellular Networks   With the development of diverse wireless communication technologies,
interference has become a key impediment in network performance, thus making
effective interference management (IM) essential to accommodate a rapidly
increasing number of subscribers with diverse services. Although there have
been numerous IM schemes proposed thus far, none of them are free of some form
of cost. It is, therefore, important to balance the benefit brought by and cost
of each adopted IM scheme by adapting its operating parameters to various
network deployments and dynamic channel conditions.
  We propose a novel IM scheme, called dynamic interference steering (DIS), by
recognizing the fact that interference can be not only suppressed or mitigated
but also steered in a particular direction. Specifically, DIS exploits both
channel state information (CSI) and the data contained in the interfering
signal to generate a signal that modifies the spatial feature of the original
interference to partially or fully cancel the interference appearing at the
victim receiver. By intelligently determining the strength of the steering
signal, DIS can steer the interference in an optimal direction to balance the
transmitter's power used for IS and the desired signal's transmission. DIS is
shown via simulation to be able to make better use of the transmit power, hence
enhancing users' spectral efficiency (SE) effectively.
