Patent ID: 11463137

Abstract:
In an embodiment, a method is for communicating in a wireless local area network (WLAN) that utilizes multi-user multiple input, multiple output (MU-MIMO). A first communication device determines an allocation of spatial streams for multiple second communication devices that are intended receivers of an multi-user multiple input, multiple output (MU-MIMO) transmission by the first communication device. The first communication device generates a subfield that indicates respective numbers of spatial streams allocated to respective second communication devices, the generating the subfield performed according to an encoding that supports allocating up to sixteen spatial streams to up to eight intended receivers. The first communication device generates a multi-user physical layer (PHY) data unit that includes i) a PHY preamble, and ii) a PHY data portion. The PHY preamble is generated to include the subfield, and the PHY data portion is generated to include the MU-MIMO transmission.
