Stochastic Muting with Short-range Relay Analysis

Resource muting in the time-frequency domain is a tool for controlling co-channel interference in cellular networks. However, coordinated resource of multiple cells implies nontrivial complexity to be effective. Moreover, resource muting does not guarantee fair resource allocation to users. However, we analytically show that stochastic resource muting jointly with opportunistic short-range relay operated by neighbor mobile devices permits to abate the complexity of muting coordination and boosts throughput fairness among users. We therefore formulate a convex proportional fairness optimization problem and leverage our analysis to design VSM-PF, a practical optimization scheme that significantly outperforms legacy systems.© 2022 IEEE.
