Abstract: This document describes multicast communication between wireless devices. A scheduling frame may be wirelessly transmitted by a wireless device. The scheduling frame may include a multicast address indicating a group of intended receiving devices for a payload frame. The scheduling frame may further include scheduling information indicating an order for the group of intended receiving devices to transmit acknowledgement information for the payload frame. A payload frame may also be wirelessly transmitted by the wireless device. The payload frame may include payload information intended for the group of intended receiving devices. Additionally, acknowledgement frames may be wirelessly received by the wireless device from at least a subset of the group of intended receiving devices. The acknowledgement frames may be received according to the order indicated in the scheduling information.

Abstract translation: 本文档描述了无线设备之间的组播通信。 调度帧可以由无线设备无线发送。 调度帧可以包括指示用于有效载荷帧的一组预期接收设备的多播地址。 调度帧还可以包括指示预定接收设备组的顺序的调度信息，以发送有效载荷帧的确认信息。 有效载荷帧也可以由无线设备无线传输。 有效载荷帧可以包括旨在用于预期接收设备组的有效载荷信息。 另外，确认帧可以由无线设备从预期接收设备组的至少一个子集无线地接收。 可以根据调度信息中指示的顺序接收确认帧。
