On Optimal Link Activation With Interference Cancellation in Wireless Networking
A fundamental aspect in performance engineering of wireless networks is optimizing the set of links that can be concurrently activated to meet given Signal-to-Interference-and-Noise Ratio (SINR) thresholds. The solution of this combinatorial problem is the key element in scheduling and cross-layer resource management. Previous works on link activation assume single-user decoding receivers that treat interference in the same way as noise. In this paper, the authors assume multiuser decoding receivers, which can cancel strongly interfering signals. As a result, in contrast to classical spatial reuse, links being close to each other are more likely to be active simultaneously.
