Apparatus, system and method of communicating a single-user (su) multiple-input-multiple-output (mimo) transmission

A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one processor, enable the at least one processor to cause a first Enhanced Directional Multi-Gigabit (EDMG) wireless communication station (STA) to:

• process a Request to Send (RTS) from a second EDMG STA, the RTS to initiate channel access for a transmission from the second EDMG STA to the first EDMG STA, a control trailer of the RTS comprising an indication that the transmission from the second EDMG STA to the first EDMG STA is to be a Single-User (SU) Multiple-Input-Multiple-Output (MIMO) transmission;
• and
• based on a determination that the first EDMG STA is able to receive the SU-MIMO transmission, transmit a Clear to Send (CTS) to the second EDMG STA, a control trailer of the CTS configured to indicate whether the first EDMG STA is to use a Single-Input-Single-Output (SISO) mode or a SU-MIMO mode to transmit a transmission to the second EDMG STA.

An apparatus comprising:

• means for processing at a first Enhanced Directional Multi-Gigabit (EDMG) wireless communication station (STA) a Request to Send (RTS) from a second EDMG STA, the RTS to initiate channel access for a transmission from the second EDMG STA to the first EDMG STA, a control trailer of the RTS comprising an indication that the transmission from the second EDMG STA to the first EDMG STA is to be a Single-User (SU) Multiple-Input-Multiple-Output (MIMO) transmission;
• and
• means for causing the first EDMG STA to, based on a determination that the first EDMG STA is able to receive the SU-MIMO transmission, transmit a Clear to Send (CTS) to the second EDMG STA, a control trailer of the CTS configured to indicate whether the first EDMG STA is to use a Single-Input-Single-Output (SISO) mode or a SU-MIMO mode to transmit a transmission to the second EDMG STA.
