Method and apparatus for improved multicast service using negotiated feedback

摘要

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.

1. A method for improved multicast service using negotiated feedback, the method comprising:
receiving, by a feedback mobile device from a multicast sender, a multicast transmission for a plurality of mobile devices, the feedback mobile device being one of the plurality of mobile devices, the plurality of mobile devices further including a group of non-feedback mobile devices; transmitting by the feedback mobile device 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; receiving, by the feedback mobile device 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; transmitting by the feedback mobile device an indication of the non-feedback mobile channel quality to the multicast sender and to the group of non-feedback mobile devices, wherein transmitting by the feedback mobile device the 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 comprises transmitting the indication of feedback mobile channel quality to the multicast sender and separately to the group of non-feedback mobile devices, and wherein transmitting by the feedback mobile device the indication of the non-feedback mobile channel quality to the multicast sender and to the group of non-feedback mobile devices comprises transmitting by the feedback mobile device the indication of the non-feedback mobile channel quality to the multicast sender and separately to the group of non-feedback mobile devices.
