CLAIMS

What is claimed is:

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

allocate one or more service periods for one or more resource allocations during a data transmission interval (DTI) of a beacon interval;

determine an extended schedule element, the extended schedule element

comprising an indication of a time division duplex (TDD) type of at least one of the one or more service periods;

determine a frame comprising the extended schedule element; and

cause to send the frame to one or more station devices.

2. The device of claim 1, wherein the at least one of the one or more service periods is associated with an enhanced directional multi-gigabit (EDMG) channel access.

3. The device of claim 1, wherein the at least one of the one or more service periods comprises one or more TDD intervals, the one or more TDD intervals comprising a first set of TDD slots and a second set of TDD slots.

4. The device of claim 3, wherein the first set of TDD slots is allocated for downlink traffic and the second set of TDD slots is allocated for uplink traffic.

5. The device of claim 1, wherein two consecutive TDD slots are separated by a time gap.

6. The device of claim 1, wherein the one or more service periods comprise at least one of a contention based service period, a scheduled service period, or a TDD service period.

7. The device of claim 1, wherein the memory and the processing circuitry are further configured to set a service period allocation subfield in the extended schedule element to a first value, wherein the first value indicates a service period with TDD channel access.

8. The device of claim 7, wherein the service period allocation subfield is included in an allocation control field of the extended schedule element.

9. The device of claim 7, wherein the first value is set to "1" to indicate a service period with TDD channel access.

10. The device of claim 1, wherein the first value is set to "0" to indicate a scheduled service period.

11. The device of any one of claims 1-10, wherein the memory and the processing circuitry are further configured to determine an enhanced directional multi-gigabit (EDMG) slot structure information element indicating a scheduling structure of a TDD slot.

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

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

14. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising: identify a frame received from an access point;

identify an extended schedule element included in the frame, wherein the extended schedule element comprises an indication of a time division duplex (TDD) service period one or more service periods; and

cause to send an uplink frame in at least one TDD slot of the TDD service period to the access point.

15. The non-transitory computer-readable medium of claim 14, wherein the frame is one of a beacon frame or an announce frame.

16. The non-transitory computer-readable medium of any one of claims 14-15, wherein the TDD service period is comprised of one or more TDD intervals, the one or more TDD intervals comprising a first set of TDD slots and a second set of TDD slots.

17. The non-transitory computer-readable medium of claim 16, wherein the first set of TDD slots is allocated for downlink traffic and the second set of TDD slots is allocated for uplink traffic.

18. A method comprising:

allocating, by one or more processors, one or more service periods for one or more resource allocations during a data transmission interval (DTI) of a beacon interval;

determining an extended schedule element, the extended schedule element

comprising an indication of a time division duplex (TDD) type of at least one of the one or more service periods;

determining a frame comprising the extended schedule element; and

causing to send the frame to one or more station devices.

19. The method of claim 18, wherein the at least one of the one or more service periods is associated with an enhanced directional multi-gigabit (EDMG) channel access.

20. The method of any one of claims 18-19, wherein the at least one of the one or more service periods comprises one or more TDD intervals, the one or more TDD intervals comprising a first set of TDD slots and a second set of TDD slots.

21. The method of claim 20, wherein the first set of TDD slots is allocated for downlink traffic and the second set of TDD slots is allocated for uplink traffic.

22. An apparatus comprising means for:

allocating, by one or more processors, one or more service periods for one or more resource allocations during a data transmission interval (DTI) of a beacon interval;

determining an extended schedule element, the extended schedule element

comprising an indication of a time division duplex (TDD) type of at least one of the one or more service periods;

determining a frame comprising the extended schedule element; and

causing to send the frame to one or more station devices.

23. The apparatus of claim 22, wherein the at least one of the one or more service periods is associated with an enhanced directional multi-gigabit (EDMG) channel access.

24. The apparatus of any one of claims 22-23, wherein the at least one of the one or more service periods comprises one or more TDD intervals, the one or more TDD intervals comprising a first set of TDD slots and a second set of TDD slots.

25. The apparatus of claim 24, wherein the first set of TDD slots is allocated for downlink traffic and the second set of TDD slots is allocated for uplink traffic.
