Multi-user preamble format for a wireless local area network

Abstract:

Methods, systems, and devices for wireless communications are described for control signaling in next generation wireless local area network (WLAN) environments. A message transmitted by an access point may allocate resources to a plurality of stations. The access point may be configured to allocate up to 320 MHz of total bandwidth along with coarse punctures. The access point may also allocate up to eight space-time streams to each station in a multi-user multiple-input multiple output (MU-MIMO) transmission, and support simultaneous transmission to up to sixteen stations. To support 320 MHz bandwidth and up to sixteen stations, one or more signaling fields used in other environments may be repurposed to effectively signal the additional resources available in a next generation WLAN.
