Wireless Technologies with Standard Interference Properties

The standard interference (SI) framework denotes a set of mathematical properties claimed capable of describing interference in numerous wireless technologies. By showing that interference behaves »standard», so the idea, known algorithms for power control and interference management can be reapplied to novel technologies. Even further, interference across physical (PHY) layers can be managed with a single technique based on SI, as long as all involved technologies behave standard. Although some examples for technologies with standard interference are well-known, e.g., single-channel communication and beamforming, a systematic search for systems with standard properties has not been done in literature. In this work, we present proofs for the standard behavior of interference in numerous wireless technologies. We show that apart from common single-input single-output (SISO) links, also links with transmit- and receive beamforming, successive interference cancellation (SIC), amplify and forward (AF) relaying and fullduplex (FD) communication exhibit standard properties. Further, the standard property can be claimed for links with probabilistic channels and-or transmissions, such as ALOHA based networks. Finally, we investigate multi-channel interference. By leveraging the newly proven result that standard properties can directly be deduced from the associated rate function, we find that interference in multi-channel and multi-input multi-output (MIMO) systems, too, exhibit the standard properties. The variety of SI systems motivates that although abstract, standard interference has the potential to create a generalized interference management framework, capable of incorporating most existing communication types.
