Abstract

This disclosure relates to transmitting multicast information over a network, such as a wireless local area network (WLAN). A source device may transmit a multicast and a request for feedback to a plurality of sink devices. The sink devices may transmit feedback based on whether they successfully decoded the multicast. The source device may retransmit the multicast (or a portion thereof) based on the feedback.
