Abstract

Some demonstrative embodiments include apparatuses, systems and/or methods of communicating a Single-User (SU) Multiple-Input-Multiple-Output (MIMO) transmission. For example, a first wireless communication station may be configured to transmit a Request to Send (RTS) to a second wireless communication station via a plurality of SU MIMO Transmit (Tx) sectors of the first wireless communication station, the RTS to establish a Transmit Opportunity (TXOP) to transmit an SU-MIMO transmission to the second wireless communication station, a control trailer of the RTS including an indication of an intent to transmit the SU-MIMO transmission to the second wireless communication station; and to transmit the SU-MIMO transmission to the second wireless communication station, upon receipt of a Clear to Send (CTS) from the second wireless communication station indicating that the second wireless communication station is ready to receive the SU-MIMO transmission.

Claims (40)

1. An apparatus comprising:

memory circuitry; and

a processor comprising logic and circuitry configured 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.

2. The apparatus of claim 1 configured to cause the first EDMG STA to set a SISO/MIMO field and a SU/Multi-user (MU) MIMO field in the control trailer of the CTS to indicate whether the first EDMG STA is to use the SISO mode or the SU-MIMO mode for the transmission to the second EDMG STA.

3. The apparatus of claim 1 configured to cause the first EDMG STA to set a SISO/MIMO field in the control trailer of the CTS to “1” and a SU/Multi-user (MU) MIMO field in the control trailer of the CTS to “0”, when the first EDMG STA is to use the SU-MIMO mode for the transmission to the second EDMG STA.

4. The apparatus of claim 1 configured to cause the first EDMG STA to set a SISO/MIMO field in the control trailer of the CTS to “0”, when the first EDMG STA is to use the SISO mode for the transmission to the second EDMG STA.

5. The apparatus of claim 1 configured to cause the first EDMG STA to:

set the control trailer of the CTS to indicate that the first EDMG STA is to use the SISO mode; and

transmit the CTS using the SISO mode.

6. The apparatus of claim 1 configured to cause the first EDMG STA to:

set the control trailer of the CTS to indicate that the first EDMG STA is to use the SU-MIMO mode; and

transmit the CTS using the SU-MIMO mode.

7. The apparatus of claim 6 , wherein the control trailer of the CTS comprises an indication of an antenna configuration for the transmission to the second EDMG STA in the SU-MIMO mode.

8. The apparatus of claim 1 , wherein the control trailer of the RTS comprises a SISO/MIMO field set to “1”, and a SU/Multi-user (MU) MIMO field set to “0” to indicate that the transmission from the second EDMG STA to the first EDMG STA is to be the SU-MIMO transmission.

9. The apparatus of claim 1 , wherein the control trailer of the RTS comprises an indication of an antenna configuration for the SU-MIMO transmission.

10. The apparatus of claim 1 configured to cause the first EDMG STA to transmit a Denial to Send (DTS) to the second EDMG STA, based on a determination that the first EDMG STA is not able to receive the SU-MIMO transmission.

11. The apparatus of claim 1 configured to cause the first EDMG STA to process a grant frame from the second EDMG STA, the grant frame comprising an indication of a time for the channel access, wherein a control trailer of the grant frame comprises an indication of the SU-MIMO transmission.

12. The apparatus of claim 11 configured to cause the first EDMG STA to transmit a grant acknowledge (ACK) to the second EDMG STA based on the determination that the first EDMG STA is able to receive the SU-MIMO transmission.

13. The apparatus of claim 12 configured to cause the first EDMG STA to configure a control trailer of the grant ACK to indicate whether the first EDMG STA is to use the SISO mode or the SU-MIMO mode to transmit to the second EDMG STA.

14. The apparatus of claim 1 configured to cause the first EDMG STA to process a Contention-Free End (CF-END) frame from the second EDMG STA, the CF-END frame to release a Transmit Opportunity (TxOP) used for the SU-MIMO transmission.

15. The apparatus of claim 1 comprising a radio, the processor configured to cause the radio to transmit the CTS.

16. The apparatus of claim 15 comprising one or more antennas connected to the radio, and another processor to execute instructions of an operating system.

17. 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.

18.
