1. A method for transmitting data in a wireless local area network (WLAN), comprising:

transmitting, in the WLAN, a trigger frame from a first wireless communication device, the trigger frame comprising one or more U-Sig-Disregard subfields of bits totaling 11 bits at predefined bit locations within the trigger frame that are populated with values for a second wireless communication device to copy into an 11-bit U-Sig-Disregard field of a trigger based frame for transmission to the first wireless communication device.

2. The method of claim 1 , wherein the trigger frame has a common information field, the common information field having the one or more U-Sig-Disregard subfields of bits.

5. The method of claim 4 , wherein the one or more U-Sig-Disregard subfields of bits are 11 bits included within 5 octets of bits at a beginning of the user information field.

6. The method of claim 4 , wherein the one or more U-Sig-Disregard subfields of bits are 11 bits of the user information field, the 11 bits being contiguous or non-contiguous.

7. A method for transmitting data in a wireless local area network (WLAN), comprising:

receiving, by a station (STA) in the WLAN, a trigger frame, and in response to the trigger frame:

copying content from 11 predefined bit locations of the trigger frame corresponding to one or more U-Sig-Disregard subfields of bits into 11 predefined U-Sig-Disregard field bit locations of a response frame; and

transmitting, by the STA, the response frame.

9. The method of claim 7 , wherein the 11 predefined U-Sig-Disregard field bit locations of the trigger frame comprise 11 bits determined from a user info list field of the trigger frame, the 11 bits being 11 contiguous bits.

10. The method of claim 7 , wherein the 11 predefined U-Sig-Disregard field bit locations of the trigger frame comprise 11 bits determined from a user info list field of the trigger frame, the 11 bits being non-contiguous bits.

11. A wireless communication device for transmitting data in a wireless local area network (WLAN), the wireless communication device comprising:

a processor;

a memory coupled to the processor, the memory tangibly storing thereon executable instructions that, when executed by the processor, cause the wireless communication device to:

transmit, in the WLAN, a trigger frame from a first wireless communication device, the trigger frame comprising one or more U-Sig-Disregard subfields of bits totaling 11 bits at predefined bit locations within the trigger frame that are populated with values for a second wireless communication device to copy into an 11-bit U-Sig-Disregard field of a trigger based frame for transmission to the first wireless communication device.

12. The device of claim 11 , wherein the trigger frame has a common information field, the common information field having the one or more U-Sig-Disregard subfields of bits.

13. The device of claim 12 , wherein the common information field has at least 63 bits and the one or more U-Sig-Disregard subfields of bits are included in bit locations 53 to 63 .

14. The device of claim 11 , wherein the trigger frame includes a user information field, the user information field having the one or more U-Sig-Disregard subfields of bits.

15. The device of claim 14 , wherein the one or more U-Sig-Disregard subfields of bits are 11 bits included within 5 octets of bits at a beginning of the user information field.

16. The device of claim 14 , wherein the one or more U-Sig-Disregard subfields of bits are 11 bits of the user information field, the 11 bits being contiguous or non-contiguous.

17. A wireless communication device for transmitting data in a wireless local area network (WLAN), the wireless communication device comprising:

a processor;

a memory coupled to the processor, the memory tangibly storing thereon executable instructions that, when executed by the processor, cause the wireless communication device to:

receive a trigger frame, and in response to the trigger frame:

copy content from 11 predefined bit locations of the trigger frame corresponding to one or more U-Sig-Disregard subfields of bits into 11 predefined U-Sig-Disregard field bit locations of a response frame; and

transmit the response frame.

18. The device of claim 17 , wherein the 11 predefined U-Sig-Disregard field bit locations of the response frame are locations B 20 to B 25 of a universal signal 1 (U-SIG- 1 ) subfield and B 11 to B 15 of a universal signal 2 (U-SIG- 2 ) subfield of a universal signal (U-SIG) field of an EHT trigger based (TB) physical layer protocol data unit (PPDU).

19. The device of claim 17 , wherein the 11 predefined U-Sig-Disregard field bit locations of the trigger frame comprise 11 bits determined from a user info list field of the trigger frame, the 11 bits being 11 contiguous bits.

20. The device of claim 17 , wherein the 11 predefined U-Sig-Disregard field bit locations of the trigger frame comprise 11 bits determined from a user info list field of the trigger frame, the 11 bits being non-contiguous bits.
