Abstract
Wireless communication networks may use various techniques, including those that use multiple-access techniques such as multi-user multiple-input multiple-output (MU-MIMO) techniques. In some embodiments, the use of a MU-MIMO setup frame may give a destination STA a chance to select a best antenna weight vector (AWV) based on previous antenna training. In particular, the use of an AWVgroupID may be used to identify a group of one or more STAs that can be the destination STAs of the MU-MIMO setup frame.

- encode a multiple-input multiple-output (MIMO) setup frame that includes multiple group identifiers, each group identifier associated with multiple station (STA) address identifiers, each of the multiple STA address identifiers associated with an antenna weight vector (AWV) for directional reception;
- and
- transmit the MIMO setup frame to multiple STAs associated with the multiple STA address identifiers.
A computer-readable non-transitory storage medium that contains instructions, which when executed by one or more processors result in performing operations comprising:
- encoding a multiple-input multiple-output (MIMO) setup frame that includes multiple group identifiers, each group identifier associated with multiple station (STA) address identifiers, each of the multiple STA address identifiers associated with an antenna weight vector (AWV);
