Abstract
A first client station receives a multi-user physical layer (PHY) data unit from an access point. The multi-user PHY data unit includes i) a PHY preamble, and ii) a multi-user multiple input, multiple output (MU-MIMO) transmission. The PHY preamble includes a subfield that indicates respective numbers of spatial streams allocated to respective client stations among a plurality of client station that includes the first client station. The subfield has been encoded according to an encoding that supports allocating up to sixteen spatial streams to up to eight intended receivers, and the subfield consists of six or fewer bits. The first client station decodes the subfield to determine a number of spatial streams allocated to the first client station and processes the determined number of spatial streams in the MU-MIMO transmission.
