Side Channel: Bits Over Interference

Interference is a critical issue in wireless communications. In a typical multiple-user environment, different users may severely interfere with each other. Coordination among users therefore is an indispensable part for interference management in wireless networks. It is known that, coordination among multiple nodes is a costly operation taking a significant amount of valuable communication resource. In this paper, the authors have an interesting observation that by generating intended patterns, some simultaneous transmissions, i.e., "Interference", can be successfully decoded without degrading the effective throughput in original transmission. As such, an extra and "Free" coordination channel can be built.
