METHOD, WIRELESS LOCAL AREA NETWORK (WLAN), NODE AND APPARATUS FOR MULTICAST AND/OR BROADCAST ACKOWLEDGEMENTS

摘要

The present invention provides a new and unique method and apparatus for communicating information between two nodes, points or terminals in a wireless local area network (WLAN), wherein multicast and broadcast data is transmitted in a power save multi poll (PSMP) scheme and the transmitted data is acknowledged between the two nodes, points or terminals in the wireless LAN network. The two nodes, points or terminals may include an access point (AP) or other suitable network node or terminal and a station (STA) or other suitable network node or terminal in the WLAN.
