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.

First claim

What is claimed is:

1. An apparatus comprising:
memory circuitry; and
a processor configured to cause a first Enhanced Directional Multi-Gigabit (EDMG) station (STA) to:
process a grant frame from a second EDMG STA, the grant frame to indicate a target time when the second EDMG STA is intended to initiate Multiple-Input-Multiple-Output (MIMO) channel access to transmit to the first EDMG STA, wherein a control trailer of the grant frame comprises an indication that a transmission to the first EDMG STA is to be a Single-User (SU) MIMO (SU-MIMO) transmission; and
based on a determination that the first EDMG STA is able to receive the SU-MIMO transmission at the target time, transmit a grant Acknowledgement (Ack) frame to the second EDMG STA.

2. The apparatus of claim 1 configured to cause the first EDMG STA to set a control trailer of the grant Ack frame 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.

3. The apparatus of claim 2 configured to cause the first EDMG STA to set a SISO/MIMO field in the control trailer of the grant Ack frame 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.

4. The apparatus of claim 2 configured to cause the first EDMG STA to set a SISO/MIMO field in the control trailer of the grant Ack frame to “1” to indicate that the first EDMG STA is to use the SU-MIMO mode for the transmission to the second EDMG STA.

5. The apparatus of claim 4 configured to cause the first EDMG STA to set the control trailer of the grant Ack frame to indicate an antenna configuration for the transmission to the second EDMG STA using the SU-MIMO mode.

6. The apparatus of claim 2 configured to cause the first EDMG STA to set a SISO/MIMO field in the control trailer of the grant Ack frame to “0” to indicate that the first EDMG STA is to use the SISO mode for the transmission to the second EDMG STA.

7. The apparatus of claim 1 configured to cause the first EDMG STA to configure antennas of the first EDMG STA according to an antenna setting indicated by the control trailer of the grant frame.

8. The apparatus of claim 7 configured to cause the first EDMG STA to configure the antennas of the first EDMG STA according to the antenna setting within a time period based on a value in an allocation duration field of the grant frame and a value in a duration field of the grant frame.

9. The apparatus of claim 7 configured to cause the first EDMG STA to configure the antennas of the first EDMG STA according to the antenna setting within a time period from a PHY Transmit end indication (PHY-TXEND.indication) of the grant frame, wherein the time period is based on a sum of a value of an allocation duration field of the grant frame and a value of a duration field of the grant frame.

10. The apparatus of claim 1 configured to cause the first EDMG STA to identify the target time based on an allocation duration field of the grant frame and a duration field of the grant frame.

11. The apparatus of claim 10 configured to cause the first EDMG STA to identify the target time based on a sum of a value of the allocation duration field and a value of the duration field.

12. The apparatus of claim 1 comprising a radio, the processor configured to cause the radio to transmit the grant Ack frame from the first EDMG STA.

13. The apparatus of claim 12 comprising one or more antennas connected to the radio, and another processor to execute instructions of an operating system.

14. 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 first Enhanced Directional Multi-Gigabit (EDMG) station (STA) to:
process a grant frame from a second EDMG STA, the grant frame to indicate a target time when the second EDMG STA is intended to initiate Multiple-Input-Multiple-Output (MIMO) channel access to transmit to the first EDMG STA, wherein a control trailer of the grant frame comprises an indication that a transmission to the first EDMG STA is to be a Single-User (SU) MIMO (SU-MIMO) transmission; and
based on a determination that the first EDMG STA is able to receive the SU-MIMO transmission at the target time, transmit a grant Acknowledgement (Ack) frame to the second EDMG STA.

15. The product of claim 14 , wherein the instructions, when executed, cause the first EDMG STA to set a control trailer of the grant Ack frame 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.

16. The product of claim 14 , wherein the instructions, when executed, cause the first EDMG STA to configure antennas of the first EDMG STA according to an antenna setting indicated by the control trailer of the grant frame.

17. The product of claim 14 , wherein the instructions, when executed, cause the first EDMG STA to identify the target time based on an allocation duration field of the grant frame and a duration field of the grant frame.

18. The product of claim 17 , wherein the instructions, when executed, cause the first EDMG STA to identify the target time based on a sum of a value of the allocation duration field and a value of the duration field.

19. An apparatus comprising:
means for causing a first Enhanced Directional Multi-Gigabit (EDMG) station (STA) to process a grant frame from a second EDMG STA, the grant frame to indicate a target time when the second EDMG STA is intended to initiate Multiple-Input-Multiple-Output (MIMO) channel access to transmit to the first EDMG STA, wherein a control trailer of the grant frame comprises an indication that a transmission to the first EDMG STA is to be a Single-User (SU) MIMO (SU-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 at the target time, transmit a grant Acknowledgement (Ack) frame to the second EDMG STA.

20. The apparatus of claim 19 comprising means for causing the first EDMG STA to set a control trailer of the grant Ack frame 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.
