1. A system comprising:
a station comprising a radio and a processing circuit,
the processing circuit being configured to:
send, to an access point, an Operating Mode Indication (OMI) declaring a change in a station Modulation Coding Scheme (MCS) capability for a third number of spatial streams based on the station detecting performance degradation with an MCS configuration negotiated during association, wherein the OMI comprises a first field associated with a Multi-User (MU) MCS capability and a second field associated with a Single-User (SU) MCS capability.
