We investigate the outage probability of a dual-hop MIMO system where amplify-and-forward relay and beamforming are used. A practically important case where proportional fair scheduling is implemented to schedule users transmissions and co-channel interference exists is considered in the analysis. Specifically, taking into account Rayleigh fading and the path-loss e↵ect, we derive the lower bound and the asymptotic expressions of the outage probability in closed form, with arbitrary number of antennas and users. The proposed results are validated via Monte Carlo simulations.
