Systems, methods, and instrumentalities are disclosed for adaptation of multiple input multiple output (MIMO) mode in mmW Wireless Local Area Network (WLAN) systems. A first station (STA) may receive a mode change request from a second STA. The mode change request may indicate a mode change for a MIMO mode, a polarization mode, and/or an orthogonal frequency-division multiple access (OFDMA) mode. The mode change request may include one or more STA fields. The one or more STA fields may include a STA field associated with the first STA. Each of the one or more STA fields may include a MIMO mode subfield, a polarization mode subfield, and/or an OFDMA mode subfield. The first STA may change the MIMO mode, the polarization mode, and/or the OFDMA mode, for example, based on the mode change request. The first STA may send a mode change response to the second STA. 1. A first station (STA) comprising: receive, from a second STA, a mode measurement setup frame that indicates the first STA, one or more transmit beams, and one or more of a multiple input multiple output (MIMO) mode, a polarization mode, or an orthogonal frequency-division multiple access (OFDMA) mode;', 'enable one or more of the MIMO mode, the polarization mode, or the OFDMA mode indicated in the mode measurement setup frame;', 'measure the one or more transmit beams during a training period;', 'send, to the second STA, first training feedback associated with the one or more transmit beams;', 'receive, from the second STA, a mode change request that indicates a mode change for one or more of the MIMO mode, the polarization mode, or the OFDMA mode;', 'change one or more of the MIMO mode, the polarization mode, or the OFDMA mode based on the mode change request; and', 'send, to the second STA, a mode change response associated with the change to the one or more of the MIMO mode, the polarization mode, or the OFDMA mode., 'a processor configured to2. The first STA of claim 1 , wherein the training period is a ...
