We first consider a scenario where there are only two forward messages and feedback is offered through the backward IC for aiding forward-message transmission. For a linear deterministic model of this channel, we develop inner and outer bounds that match for a wide range of channel parameters. We find that the backward IC can be more efficiently used for feedback rather than if it were used for independent backward-message transmission. As a consequence, we show that feedback can provide a net increase in capacity even if feedback cost is taken into consideration. Moreover we extend this to a more general scenario with two additional independent backward messages, from which we find that interaction can provide an arbitrarily large gain in capacity. © 2012 IEEE.Channel parameter; Deterministic models; Interference channels; Outer bounds; Information theory; Signal interferenceconference paper10.1109/ISIT.2012.62840342-s2.0-84867522671
