Method and apparatus for improved multicast service using negotiated feedback
Various methods and devices are provided to address the need for improved multicast operation. In one method, a feedback mobile device receives ( 301 ), from a multicast sender, a multicast transmission for a plurality of mobile devices, the plurality of mobile devices further including a group of non-feedback mobile devices. The feedback mobile device transmits ( 302 ) an indication of feedback mobile channel quality observed by the feedback mobile device to the multicast sender and to the group of non-feedback mobile devices. The feedback mobile device receives ( 303 ) from at least one non-feedback mobile device, an indication of non-feedback mobile channel quality at the at least one non-feedback mobile device and transmits ( 304 ) an indication of the non-feedback mobile channel quality to the multicast sender and to the group of non-feedback mobile devices.
