Elements of Cellular Blind Interference Alignment - Aligned Frequency Reuse, Wireless Index Coding and Interference Diversity

The authors explore Degrees of Freedom (DoF) characterizations of partially connected wireless networks, especially cellular networks, with no channel state information at the transmitters. Specifically, they introduce three fundamental elements - aligned frequency reuse, wireless index coding and interference diversity - through a series of examples, focusing first on infinite regular arrays, then on finite clusters with arbitrary connectivity and message sets, and finally on heterogeneous settings with asymmetric multiple antenna configurations. Aligned frequency reuse refers to the optimality of orthogonal resource allocations in many cases, but according to unconventional reuse patterns that are guided by interference alignment principles.
