Abstract

This disclosure describes systems, methods, and devices related to multiple-input and multiple-output (MIMO) beamforming. A device may determine one or more short sector sweep frames associated with one or more antennas of the device. The device may cause to set one or more fields of at least one of the one or more short sector sweep frames to indicate an MIMO communication with one or more first devices. The device may identify one or more response frames from at least one of the one or more first devices based at least in part on the one or more short sector sweep frames.

Claims (36)

1. A device, the device comprising memory and processing circuitry configured to:

determine one or more short sector sweep frames associated with one or more antennas of the device, wherein the one or more short sector sweep frames include at least in part an addressing mode field, a duration field, and an addressing field;

cause to set one or more fields of at least one of the one or more short sector sweep frames to indicate a multiple-input and multiple-output (MIMO) communication with one or more first devices;

determine one or more information elements associated with the one or more short sector sweep frames, wherein the one or more information elements include at least in part one or more group IDs associated with one or more first devices;

cause to send the one or more short sector sweep frames to the one or more first devices; and

identify one or more response frames from at least one of the one or more first devices based at least in part on the one or more short sector sweep frames.

2. The device of claim 1 , wherein the addressing mode field indicates that the MIMO communication is a multiuser (MU) communication or a single user (SU) communication with at least one of the one or more first devices.

3. The device of claim 1 , wherein the addressing field is associated with the one or more group IDs.

4. The device of claim 1 , wherein the memory and the processing circuitry are further configured to assign the at least one of the one or more first devices to at least one of the one or more group IDs.

5. The device of claim 1 , wherein the memory and the processing circuitry are further configured to cause to send one or more setup frames associated with the one or more first devices.

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

7. The device of claim 6 , further comprising one or more antennas coupled to the transceiver.

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

identifying one or more short sector sweep frames associated with one or more antenna sectors of a device, wherein the one or more short sector sweep frames include at least in part an addressing mode field, a duration field, and an addressing field;

identifying one or more information elements (IEs) received in at least one of a beacon frame, an announce frame, or a trigger frame, wherein the one or more IEs include at least in part one or more group IDs associated with one or more first devices;

identifying at least one of an addressing mode field, a duration field, and an addressing field within at least one of the one or more short sector sweep frames; and

determining a type of communication with the device based at least in part on the addressing mode field and the addressing field.

9. The non-transitory computer-readable medium of claim 8 , wherein the type of communication is at least one of a single user or a multiuser multiple-input multiple-output (MIMO) communication.

10. The non-transitory computer-readable medium of claim 8 , wherein the addressing field is associated with the one or more group IDs.

11. The non-transitory computer-readable medium of claim 8 , wherein the operations further comprise:

determining a device identification (ID) associated with one of the one or more first devices;

determining the device ID is associated with the one or more group IDs;

identifying an MIMO setup message received from the device; and

causing to send an MIMO response message to the device.

12. The non-transitory computer-readable medium of claim 8 , wherein the operations further comprise:

determining a device identification (ID) associated with one of the one or more first devices;

determining the device ID is not associated with the one or more group IDs; and

causing to enter an inactive mode for a time duration included in the duration field of at least one of the one or more short sector sweep frames.

13. A method comprising:

determining one or more short sector sweep frames associated with one or more antennas of a device, wherein the one or more short sector sweep frames include at least in part an addressing mode field, a duration field, and an addressing field;

setting one or more fields of at least one of the one or more short sector sweep frames to indicate a multiple-input and multiple-output (MIMO) communication with one or more first devices;

identifying one or more information elements associated with the one or more short sector sweep frames, wherein the one or more information elements include at least in part one or more group IDs associated with one or more first devices;

sending the one or more short sector sweep frames to the one or more first devices; and

identifying one or more response frames from at least one of the one or more first devices based at least in part on the one or more short sector sweep frames.

14. The method of claim 13 , further includes determining one or more information elements associated with the one or more short sector sweep frames.

15. The method of claim 14 , wherein the one or more information elements include at least in part one or more group IDs associated with the at least one of the one or more first devices.
