In this paper, the authors propose a novel technique for the provisioning of multicast streaming flows in 3G W-CDMA cellular systems. The authors' focus here is on the transmission of a downlink multicast streaming flow to the interested users in a 3G cell. Over such networks, due to multi-user interference and channel impairments such as, e.g., deep fading phenomena, some error control features have to be provided in order to meet QoS guarantees. In previously proposed work, the wanted error resilience is achieved by exploiting Common CHannel (CCH) transmissions and retransmitting lost packets according to multi-users HARQ schemes.
