In this paper, the problem of selecting the best relay using the Amplify-and-Forward method for interference forwarding is investigated in heterogeneous cellular networks. A macrocell user is modeled as a victim exposed to the interference due to the Femtocell network, and 3 macrocell users close to the victim are used as a relay to provide interference forwarding. The links between stations-users and users-users are designed as an unrelated Rayleigh channel model. The best relay selection is made based on distance and small scale channel fading. Computer simulations show success rate against the targeted spectral efficiency.
