LOW LATENCY MULTICAST WIRELESS COMMUNICATION

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for low latency multicast wireless communication. In one aspect, multicast wireless communication may be used in a wireless local area network (WLAN) to distribute audio or video information from an access point to multiple stations. To maintain reliability and low latency, techniques of this disclosure include link training, link adaptation, and blind retries using different transmission rates. In some implementations, a station that detects a link deterioration (such as a loss of data or change in channel quality) can send an unsolicited action frame to the access point. Using the techniques in this disclosure, the access point and the station(s) may maintain the reliability of the multicast wireless communication.
