Uniform and Non-Uniform Delay-Rate Tradeoffs in Partial Ergodic Interference Alignment


H. Maier, R. Mathar,


        The impact of significantly long delays is a central problem one has to face in the ergodic interference alignment scheme. In this work, we consider the delay-rate tradeoff in a fully connected K-user Gaussian interference channel through the lens of partial interference alignment. In the concept of partial interference alignment, only a subset of user-pairs with a favorable interference pattern is aligned. We explore two flexible communication schemes: At first, we propose a scheme with uniform delay-rate demands. Then we introduce the delayrate tradeoff for a case of non-uniform demands such that also imbalanced delays and rates can be investigated.
