Apparatus, system, and method of communicating a packet including a multiple-input-multiple-output (mimo) training (trn) field

An apparatus comprising logic and circuitry configured to cause a millimeterWave (mmWave) wireless communication station (STA) to:

• transmit a preamble of a packet via a plurality of antennas of the mmWave STA over a mmWave wireless communication channel;
• and
• transmit a Multiple-Input-Multiple-Output (MIMO) Training (TRN) field of the packet over the mmWave wireless communication channel, the MIMO TRN field is after the preamble, the MIMO TRN field comprising a sequence of a plurality of MIMO TRN subfields transmitted via the plurality of antennas of the mm Wave STA, wherein a MIMO TRN subfield of the plurality of MIMO TRN subfields comprises a plurality of TRN sequences simultaneously transmitted via the plurality of antennas, respectively.

A product comprising one or more tangible computer-readable non-transitory storage media comprising instructions operable to, when executed by at least one processor, enable the at least one processor to cause a millimeterWave (mmWave) wireless communication station (STA) to:

• transmit a preamble of a packet via a plurality of antennas of the mmWave STA over a mmWave wireless communication channel;
• and
• transmit a Multiple-Input-Multiple-Output (MIMO) Training (TRN) field of the packet over the mmWave wireless communication channel, the MIMO TRN field is after the preamble, the MIMO TRN field comprising a sequence of a plurality of MIMO TRN subfields transmitted via the plurality of antennas of the mmWave STA, wherein a MIMO TRN subfield of the plurality of MIMO TRN subfields comprises a plurality of TRN sequences simultaneously transmitted via the plurality of antennas, respectively.
