ABSTRACT:
Aspects of a method and system for an optional closed loop mechanism with adaptive modulations for a multiple input multiple output (MIMO) WLAN system are provided. One aspect of the system may comprise a receiver that may select, for a plurality of spatial streams, a modulation type and/or coding rate. The receiver may communicate a message, via an RF channel, that comprises a plurality of modulation types and/or coding rates. The receiver may configure for receiving subsequent data based on at least one selected modulation type and/or coding rate. Another aspect of the system may comprise a transmitter that may receive a message, via an RF channel, that comprises a specification of, for a plurality of spatial streams, a plurality of modulation types and/or coding rates. The system may configure for transmitting subsequent data based on at least one of the received modulation types and/or coding rates.
