Abstract

This disclosure describes systems, methods, and devices related to high throughput (HT) control information. A device may determine a frame comprising HT control information. The device may determine to extend a size of the HT control information. The device may cause to generate a management or data frame for sending to a first station device of one or more station devices, the management or data frame comprising extended high throughput (HT) control information, define a new control identification (ID) associated with the extended HT control information, and cause to send the management or data frame to the first station device.

First claim

What is claimed is:

1. A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:
generate a first control identifier of a medium access control (MAC) frame indicative of a presence of an operating mode (OM) control subfield in the MAC frame;
generate a second control identifier of the MAC frame indicative of a presence of an extremely high throughput (EHT) OM control subfield in the MAC frame;
set three bits of a receive number of spatial streams (RX NSS) subfield of the OM control subfield and one bit of a RX NSS extension subfield of the EHT OM control subfield to indicate more than eight RX NSS;
set three bits of a transmit number of spatial streams (TX NSTS) subfield of the OM control subfield and one bit of a TX NSTS extension subfield of the EHT OM control subfield to indicate more than eight TX NSTS;
set two bits of a channel width subfield of the OM subfield and one bit of a channel width extension subfield of the EHT OM subfield to indicate a bandwidth greater than 80 MHz; and
transmit the MAC frame comprising a high throughput (HT) control field comprising the OM control subfield and the EHT OM control subfield.

2. The device of claim 1 , wherein the bandwidth is 320 MHz.

3. The device of claim 1 , wherein the RX NSS is sixteen.

4. The device of claim 1 , wherein the TX NSTS is sixteen.

5. The device of claim 1 , wherein the bandwidth is greater than 80 MHz and less than 320 MHz.

6. The device of claim 1 , wherein the RX NSS is greater than eight and less than sixteen.

7. The device of claim 1 , wherein the TX NSTS is greater than eight and less than sixteen.

8. The device of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals comprising the MAC frame.

9. The device of claim 8 , further comprising an antenna coupled to the transceiver to send the MAC frame.

10. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
generating a first control identifier of a medium access control (MAC) frame indicative of a presence of an operating mode (OM) control subfield in the MAC frame;
generating a second control identifier of the MAC frame indicative of a presence of an extremely high throughput (EHT) OM control subfield in the MAC frame;
setting three bits of a receive number of spatial streams (RX NSS) subfield of the OM control subfield and one bit of a RX NSS extension subfield of the EHT OM control subfield to indicate more than eight RX NSS;
setting three bits of a transmit number of spatial streams (TX NSTS) subfield of the OM control subfield and one bit of a TX NSTS extension subfield of the EHT OM control subfield to indicate more than eight TX NSTS;
setting two bits of a channel width subfield of the OM subfield and one bit of a channel width extension subfield of the EHT OM subfield to indicate a bandwidth greater than 80 MHz; and
transmitting the MAC frame comprising a high throughput (HT) control field comprising the OM control subfield and the EHT OM control subfield.

11. The non-transitory computer-readable medium of claim 10 , wherein the bandwidth is 320 MHz.

12. The non-transitory computer-readable medium of claim 10 , wherein the RX NSS is sixteen.

13. The non-transitory computer-readable medium of claim 10 , wherein the TX NSTS is sixteen.

14. The non-transitory computer-readable medium of claim 10 , wherein the bandwidth is greater than 80 MHz and less than 320 MHz.

15. The non-transitory computer-readable medium of claim 10 , wherein the RX NSS is greater than eight and less than sixteen.

16. The non-transitory computer-readable medium of claim 10 , wherein the TX NSTS is greater than eight and less than sixteen.

17. A method comprising:
generating, by processing circuitry of a device, a first control identifier of a medium access control (MAC) frame indicative of a presence of an operating mode (OM) control subfield in the MAC frame;
generating, by the processing circuitry, a second control identifier of the MAC frame indicative of a presence of an extremely high throughput (EHT) OM control subfield in the MAC frame;
setting, by the processing circuitry, three bits of a receive number of spatial streams (RX NSS) subfield of the OM control subfield and one bit of a RX NSS extension subfield of the EHT OM control subfield to indicate more than eight RX NSS;
setting, by the processing circuitry, three bits of a transmit number of spatial streams (TX NSTS) subfield of the OM control subfield and one bit of a TX NSTS extension subfield of the EHT OM control subfield to indicate more than eight TX NSTS;
setting, by the processing circuitry, two bits of a channel width subfield of the OM subfield and one bit of a channel width extension subfield of the EHT OM subfield to indicate a bandwidth greater than 80 MHz; and
transmitting, by the processing circuitry, the MAC frame comprising a high throughput (HT) control field comprising the OM control subfield and the EHT OM control subfield.

18. The method of claim 17 , wherein the bandwidth is 320 MHz.

19. The method of claim 17 , wherein the RX NSS is sixteen.

20. The method of claim 17 , wherein the TX NSTS is sixteen.
