Wireless Multicast Communication

摘要

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.
