Abstract
Certain aspects of the present disclosure provide techniques and apparatus for efficiently managing overloaded group IDs for groups of stations (STAs) receiving simultaneous transmission in a multiuser multiple-input multiple-output (MU-MIMO) scheme. In this manner, overloading for some of the groups may allow flexibility at an access point (AP) to trade off between support for more STA combinations and power savings. As disclosed herein, the group ID management scheme may be flexible enough to support APs with both overloaded and non-overloaded groups and APs with only non-overloaded groups. This scheme also achieves these benefits for overloading with a low overhead.
