Enhanced channel access for wireless communications

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

determine a first transmission opportunity (TXOP) for a first time period, wherein the first time period is allocated to the device for transmission of one or more frames to a first device on a channel;

determine an extended TXOP for a second time period, wherein the extended TXOP is allocated to the device after a time gap from the first TXOP, wherein the time gap introduces a pause between the first TXOP and the extended TXOP;

perform an enhanced distributed channel access (EDCA) operation before accessing the channel; and

cause to send a first frame of the one or more frames on the channel during the first TXOP.

2. The device of claim 1 , wherein the first time period is a maximum allowed time period.

3. The device of claim 1 , wherein the device may not transmit any frames during the time gap.

4. The device of claim 1 , wherein the processing circuitry is further configured to:

determine remaining frames from the one or more frames to be transmitted;

determine a remaining time from the first TXOP; and

determine to perform a short clear channel assessment (CCA) based on the remaining time.

5. The device of claim 1 , wherein the processing circuitry is further configured to:

determine the remaining frames from the one or more frames to be transmitted;

determine a remaining time from the first TXOP after sending the first frame;

determine the remaining time is less than two milliseconds; and

cause to pause transmissions for the duration of the time gap.

6. The device of claim 1 , wherein the processing circuitry is further configured to:

determine the remaining frames from the one or more frames to be transmitted;

determine a remaining time from the first TXOP after sending the first frame;

determine the remaining time is greater than or equal to two milliseconds; and

perform the EDCA operation before accessing the channel.

7. The device of claim 6 , wherein the processing circuitry is further configured to:

determine channel access is granted within a time value greater than 100 μs; and

perform a short clear channel assessment (CCA).

8. The device of claim 6 , wherein the processing circuitry is further configured to:

determine channel access is granted within a time value of less than 100 μs; and

cause to send a second frame of the one or more frames on the channel during the extended TXOP.

9. The device of claim 1 , wherein the processing circuitry is further configured to:

set a network allocation vector (NAV) value to be greater than or equal to the first time period, the extended TXOP, and the time gap; and

cause to send a third frame including the NAV value to the first device on the channel.

10. The device of claim 1 , wherein the third frame is a request to send (RTS) frame.

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

12. The device of claim 11 , further comprising an antenna coupled to the transceiver.

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

determining a first transmission opportunity (TXOP) for a first time period, wherein the first time period is allocated to the device for transmission of one or more frames to a first device on a channel;

determining an extended TXOP for a second time period, wherein the extended TXOP is allocated to the device after a time gap from the first TXOP, wherein the time gap introduces a pause between the first TXOP and the extended TXOP;

performing an enhanced distributed channel access (EDCA) operation before accessing the channel; and

causing to send a first frame of the one or more frames on the channel during the first TXOP.

14. The non-transitory computer-readable medium of claim 13 , wherein the first time period is a maximum allowed time period.

15. The non-transitory computer-readable medium of claim 13 , wherein the device may not transmit any frames during the time gap.

16. The non-transitory computer-readable medium of claim 13 , wherein the operations further comprise:

determining remaining frames from the one or more frames to be transmitted;

determining a remaining time from the first TXOP; and

determining to perform a short clear channel assessment (CCA) based on the remaining time.

17. The non-transitory computer-readable medium of claim 13 , wherein the operations further comprise:

determining the remaining frames from the one or more frames to be transmitted;

determining a remaining time from the first TXOP after sending the first frame;

determining the remaining time is less than two milliseconds; and

causing to pause transmissions for the duration of the time gap.

18. The non-transitory computer-readable medium of claim 13 , wherein the operations further comprise:

setting a network allocation vector (NAV) value to be greater than or equal to the first time period, the extended TXOP, and the time gap; and

causing to send a third frame including the NAV value to the first device on the channel.

19. The non-transitory computer-readable medium of claim 13 , wherein the third frame is a request to send (RTS) frame.

20. A method comprising:

determining, by one or more processors of a device, a first transmission opportunity (TXOP) for a first time period, wherein the first time period is allocated to the device for transmission of one or more frames to a first device on a channel;

determining an extended TXOP for a second time period, wherein the extended TXOP is allocated to the device after a time gap from the first TXOP, wherein the time gap introduces a pause between the first TXOP and the extended TXOP;

performing an enhanced distributed channel access (EDCA) operation before accessing the channel; and

causing to send a first frame of the one or more frames on the channel during the first TXOP.
