Abstract: A new and unique method and apparatus are provided for communicating information between two nodes, points or terminals in a wireless local area network (WLAN) environment or other suitable network environment, featuring one or more steps for creating an association between multicast transmission scheduling and multicast internet protocol (IP) and ethernet addresses within a multicast transmission period, and mapping multicast transmission start times using the multicast IP or ethernet address information. The apparatus may take the form of a wireless local area network (WLAN) or other suitable network having the two nodes or points that communicate information between the same based on the association and mapping, as well as the first or second node, point or terminal in such a wireless local area network (WLAN) environment, or other suitable network environment. The first or second node, point or terminal may include an access point or a station (STA).
