Abstract
Reliable multicast delivery in wireless communication, even when a WS doesn't know its AP, is determined at the AP without the sending device. Multicast packets are received at each AP having destinations. Without altering those packets, the AP encapsulates them in an A-MSDU packet. Each A-MSDU packet is sent individually to each destination, and might encapsulate more than one multicast packet. Destinations might receive two streaming messages faster than if sent separately. AP's might choose a 1st multiple of multicast packets from a 1st source, a 2nd, different, multiple of multicast packets from a 2nd source, and a single multicast packet from a 3rd source. Individualized optimization of transmission parameters for each A-MSDU packet and each multicast packet therein. Individualized optimization of transmission parameters for the A-MSDU packet for each destination. The AP collectively optimizes delivery of distinct multicast packets to different destinations.
