With 2x2 MIMO.Enhanced with 20 MHz channels in 802.16-2009 [2] WiMAX rel 2.0: 802.16m: WirelessMAN: MIMO-SOFDMA: 2x2 MIMO 110 (20 MHz TDD) 183 (2x20 MHz FDD) 4x4 MIMO
WiMAX MIMO refers to the use of Multiple-input multiple-output communications (MIMO) technology on WiMAX, which is the technology brand name for the implementation of the standard IEEE 802.16. Background
WiMAX release 2.1, popularly branded as WiMAX 2+, is a backwards-compatible transition from previous WiMAX generations. It is compatible and interoperable with TD-LTE . Newer versions, still backward compatible, include WiMAX release 2.2 (2014) and WiMAX release 3 (2021, adds interoperation with 5G NR ).

[1] [2] MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi 4), IEEE 802.11ac (Wi-Fi 5), HSPA+ (3G), WiMAX, and Long Term Evolution (LTE). More recently, MIMO has been applied to power-line communication for three-wire installations as part of the ITU G.hn standard and of the HomePlug AV2 ...
OFDMA is considered as highly suitable for broadband wireless networks, due to advantages including scalability and use of multiple antennas (MIMO-friendliness), and ability to take advantage of channel frequency selectivity. [1] In spectrum sensing cognitive radio, OFDMA is a possible approach to filling free radio frequency bands adaptively.
