Preamble for extremely high throughput trigger based physical layer protocol data unit

1. A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:

receive a trigger frame from an associated access point (AP), wherein the trigger frame comprises one or more resource unit (RU) bandwidths (BWs) allocated to the device;

generate an extremely high throughput (EHT) physical layer protocol data unit (PPDU) based on receiving the trigger frame from the AP, wherein the PPDU comprises an EHT preamble that includes a signaling (U-SIG) field;

encode the U-SIG field with an indication of one or more resource unit (RU) bandwidth (BW) allocations to be used for sending the PPDU to the AP, wherein the indication is a value associated with a first option of one or more options of selectable RU BWs, wherein the indication is indicative of a selection of the one or more options based on a clear channel assessment (CCA) indication, irrespective of a specific RU initially designated by the AP in a trigger frame; and

cause to send the PPDU to the AP and an uplink data transmission direction.

2. The device of claim 1 , wherein the U-SIG field comprises a version independent portion and version dependent portion.

3. The device of claim 2 , wherein the version dependent portion comprises a version identifier field, an uplink (UL)/downlink (DL) field, a basic service set (BSS) color field, a transmit opportunity (TXOP) field, and a PPDU BW field.

4. The device of claim 2 , wherein the version independent portion comprises a preamble puncture indication field, a PPDU format and compression field, and reserved bits.

5. The device of claim 4 , wherein the indication is included in the reserved bits of the version dependent portion of the U-SIG field.

6. The device of claim 1 , wherein the U-SIG field further comprises a cyclic redundancy code (CRC) and a tail field.

7. The device of claim 1 , wherein the indication overrides the one or more resource RU BW allocations by the AP.

8. The device of claim 1 , wherein the selectable RU BWs are based on an idle determination of clear channel assessment (CCA).

9. The device of claim 1 , wherein the selectable RU BWs include at least an anchor 20 MHz channel.

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

receiving a trigger frame from an associated access point (AP), wherein the trigger frame comprises one or more resource unit (RU) bandwidths (BWs) allocated to the device;

generating an extremely high throughput (EHT) physical layer protocol data unit (PPDU) based on receiving the trigger frame from the access point, wherein the PPDU comprises an EHT preamble that includes a signaling (U-SIG) field;

encoding the U-SIG field with an indication of one or more resource unit (RU) bandwidth (BW) allocations to be used for sending the PPDU to the AP, wherein the indication is a value associated with a first option of one or more options of selectable RU BWs, wherein the indication is indicative of a selection of the one or more options based on a clear channel assessment (CCA) indication, irrespective of a specific RU initially designated by the AP in a trigger frame; and

causing to send the PPDU to the AP and an uplink data transmission direction.

11. The non-transitory computer-readable medium of claim 10 , wherein the U-SIG field comprises a version independent portion and version dependent portion.

12. The non-transitory computer-readable medium of claim 11 , wherein the version dependent portion comprises a version identifier field, an uplink (UL)/downlink (DL) field, a basic service set (BSS) color field, a transmit opportunity (TXOP) field, and a PPDU BW field.

13. The non-transitory computer-readable medium of claim 11 , wherein the version independent portion comprises a preamble puncture indication field, a PPDU format and compression field, and reserved bits.

14. The non-transitory computer-readable medium of claim 13 , wherein the indication is included in the reserved bits of the version dependent portion of the U-SIG field.

15. The non-transitory computer-readable medium of claim 10 , wherein the U-SIG further comprises a cyclic redundancy code (CRC) and a tail field.

16. The non-transitory computer-readable medium of claim 10 , wherein the indication overrides the one or more resource RU BW allocations by the AP.

17. The non-transitory computer-readable medium of claim 10 , wherein the selectable RU BWs are based on an idle determination of clear channel assessment (CCA).

18. The non-transitory computer-readable medium of claim 10 , wherein the selectable RU BWs include at least an anchor 20 MHz channel.

19. A method comprising:

receiving, by one or more processors of a device, a trigger frame from an associated access point (AP), wherein the trigger frame comprises one or more resource unit (RU) bandwidths (BWs) allocated to the device;

generating an extremely high throughput (EHT) physical layer protocol data unit (PPDU) based on receiving the trigger frame from the access point, wherein the PPDU comprises an EHT preamble that includes a signaling (U-SIG) field;

encoding the U-SIG field with an indication of one or more resource unit (RU) bandwidth (BW) allocations to be used for sending the PPDU to the AP, wherein the indication is a value associated with a first option of one or more options of selectable RU BWs, wherein the indication is indicative of a selection of the one or more options based on a clear channel assessment (CCA) indication, irrespective of a specific RU initially designated by the AP in a trigger frame; and

causing to send the PPDU to the AP and an uplink data transmission direction.

20. The method of claim 19 , wherein the U-SIG field comprises a version independent portion and version dependent portion.
