Abstract: A method for receiving feedback on a quality of multicast transmissions in a Wireless Local Access Network (WLAN) including a source electronic device (e.g., an access point) and a plurality of electronic devices is disclosed, according to some embodiments. The method can include (i) transmitting a plurality of multicast packets addressed to a subset of the plurality of electronic devices by the source electronic device; (ii) concurrently polling the subset of the plurality of electronic devices by the source electronic device; and (iii) receiving a plurality of block acknowledgements (BAs) from at least the subset of the plurality of electronic devices by the source electronic device. Each BA may include information on a quality of reception of two or more multicast packets received at an electronic device.
