N2 - We consider a device-to-device (D2D) aided multicast channel, where a transmitter wishes to convey a common message to many receivers and these receivers cooperate with each other. We propose a simple computationally efficient scheme requiring only statistical channel knowledge at transmitter. Our analysis in general topologies reveals that, when the number of receivers K grows to infinity, the proposed scheme guarantees a multicast rate of \frac{1}{2}\log-{2}(1+\beta\ln K) with high probability for any \beta < \beta^{\star} where \beta^{\star} depends on the network topology. This scheme undergoes a phase transition at threshold \beta^{\star}\ln K where transmissions are successful/unsuccessful with high probability when the SNR is above/below this threshold. We also analyze the outage rate of the proposed scheme in the same setting.
