MULTIUSER MULTIPLE-INPUT AND MULTIPLE-OUTPUT SETUP FRAME

1 . A device, comprising:

at least one memory that stores computer-executable instructions; and

at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to:

generate a multiuser multiple-input and multiple-output (MU-MIMO) setup frame comprising a physical layer (PHY) header and a media access control (MAC) header;

determine an indication of a control trailer after the MAC header, the MAC header comprising a first receive address (RA) field, and the control trailer comprising a second RA field, wherein the first RA or the second RA comprise one or more device identifiers (IDs); and

cause to send the MU-MIMO setup frame over a directional multi-gigabit (DMG) channel.

2 . The device of claim 1 , wherein the MAC header comprises a transmit address (TA) field, wherein the TA field is located ahead of the first RA field.

3 . The device of claim 1 , wherein the first RA field is configured to contain one or more first device IDs of the one or more device IDs.

4 . The device of claim 1 , wherein the second RA field is configured to contain one or more second device IDs of the one or more device IDs.

5 . The device of claim 1 , wherein the control trailer comprises a clear to send (CTS) response bitmap, the CTS response bitmap, including one or more bits, wherein the one or more bits are associated with at least one of the one or more device IDs.

6 . The device of claim 5 , wherein at least one of the one or more bits indicate if a first device is to send a response to the MU-MIMO setup frame, wherein the first device is associated with at least one of the one or more device IDs.

7 . The device of claim 1 , wherein the control trailer comprises scheduling information to schedule at least one of a plurality of devices in a plurality of successive physical layer convergence protocol (PLCP) protocol data units (PPDUs) within a transmit opportunity (TxOP).

8 . The device of claim 1 , wherein the MU-MIMO setup frame has a structure compatible with a DMG request to send (RTS) frame structure.

9 . The device of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals.

10 . The device of claim 9 , further comprising one or more antennas coupled to the transceiver.

11 . A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:

identifying a multiuser multiple-input and multiple-output (MU-MIMO) setup frame received from a wireless device over a directional multi-gigabit (DMG) channel, the MU-MIMO setup frame comprising a physical layer (PHY) header and a media access control (MAC) header;

determine an indication of a control trailer after the MAC header, the MAC header comprising a first receive address (RA) field, and the control trailer comprising a second RA field, wherein the first RA or the second RA comprise one or more device identifiers (IDs); and

causing to send a response to the MU-MIMO setup frame to the wireless device.

12 . The non-transitory computer-readable medium of claim 11 , wherein the computer-executable instructions cause the processor to further perform operations comprising:

identifying an MU-MIMO transmission from the wireless device, when a device ID is indicated by the first RA field or the second RA field.

13 . The non-transitory computer-readable medium of claim 11 , wherein the operations for causing to send a response to the MU-MIMO setup frame further includes the operations for causing to send a clear to send (CTS) frame to the wireless device.

14 . The non-transitory computer-readable medium of claim 11 , wherein the MAC header comprises a transmit address (TA) field, wherein the TA field is located ahead of the first RA field.

15 . The non-transitory computer-readable medium of claim 11 , wherein the first RA field is configured to contain one or more first device IDs of the one or more device IDs.

16 . The non-transitory computer-readable medium of claim 11 , wherein the control trailer comprises a clear to send (CTS) response bitmap, the CTS response bitmap, including one or more bits, wherein the one or more bits are associated with at least one of the one or more device IDs.

17 . The non-transitory computer-readable medium of claim 16 , wherein at least one of the one or more bits indicate if a first device is to send a response to the MU-MIMO setup frame, wherein the first device is associated with at least one of the one or more device IDs.

18 . A method comprising:

generating a multiuser multiple-input and multiple-output (MU-MIMO) setup frame comprising a physical layer (PHY) header and a media access control (MAC) header;

determining an indication of a control trailer after the MAC header, the MAC header comprising a first receive address (RA) field, and the control trailer comprising a second RA field, wherein the first RA or the second RA comprise one or more device identifiers (IDs); and

causing to send the MU-MIMO setup frame over a directional multi-gigabit (DMG) channel.

19 . The method of claim 18 , wherein the MAC header comprises a transmit address (TA) field, wherein the TA field is located ahead of the first RA field.

20 . The method of claim 18 , wherein the control trailer comprises a clear to send (CTS) response bitmap, the CTS response bitmap, including one or more bits, wherein the one or more bits are associated with at least one of the one or more device IDs.
