An IoT self organizing network for 5G dense network interference alignment

To achieve 1000X improvements in capacity 5G communication networks integrate a heterogeneous combination of advanced systems to increase data rate. A significant component of the improvement addressed in this paper network densification incorporates closely spaced radio access antennas to achieve high information rates. However 5G multi-user networks must cope with unprecedented levels of interference and are also susceptible to jamming. To realize high 5G channel capacity targets of 1 Gbps interference management systems are a necessity. We present a self organizing Internet of Things (IoT) network infrastructure for protecting the future 5G communication system network from self-induced co-channel interference. We introduce protocols for an IoT based interference-alignment approach. Our main contributions are the introduction of an IoT architecture capable of 5G interference alignment and a spatial dimensioning algorithm that accounts for estimation error in the 5G channel state associated with interference cancellation.
