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.

Abstract: The subject technology provides for block acknowledgment requests and block acknowledgment frames that can be used in conjunction with multicast transmissions that include multiple concurrent streams. Thus, the subject technology reduces the overhead associated with multicast transmissions that include multiple concurrent streams by aggregating the acknowledgments across multiple streams into a block acknowledgment, thereby increasing the effective throughput of such transmissions and overall network efficiency.
