This paper considers the problem of multiuser resource allocation for multicasting stream video traffic over a wireless time-division multiplexing system. Most of previous work attempts to guarantee the reliability of data transmission for every user by limiting the multicast rate to the lowest instant sustainable rate of the worst user. Such rate allocation schemes may seriously penalize users with better channel conditions. Our proposed approaches attempt to exploit the multiuser diversity by dynamically selecting the rate which is not necessarily the lowest sustainable rate in order to maximize the total goodput. Simulation results conclusively demonstrate that the proposed approaches can improve the wireless channel efficiency, especially when there are more users in the multicast group.
