Abstract
Various methods and devices are provided to address the need for improved multicast operation. In one method, a sender transmits multicast transmissions at a first transmission rate to a multicast group of mobile devices that includes a group of feedback mobile devices. The sender receives, from each feedback mobile device of the group of feedback mobile devices, multicast receive quality feedback corresponding to the multicast transmissions. A new transmission rate for subsequent multicast transmissions to the multicast group of mobile devices is then determined using the multicast receive quality feedback received from each feedback mobile device, a lower multicast receive quality level threshold and a higher multicast receive quality level threshold.
