Systems and method of target wake time for peer-to-peer communication
View Patent ↗Disclosed herein are systems and methods related to systems and methods of target wake time for peer-to-peer communication. In one aspect, a first wireless communication devices configures a subfield indicating to extend a restricted target wake time (rTWT) for peer-to-peer communication. The first wireless communication device sends a message including the subfield to a second wireless communication device.
1. A method comprising:
configuring, by a first wireless communication device, a subfield indicating to extend a restricted target wake time (rTWT) for peer-to-peer (P2P) communication;
sending, by the first wireless communication device to a second wireless communication device, a message including the subfield, wherein the subfield comprises a bit that indicates whether a service period is requested for P2P communication; and
communicating, by the second wireless communication device, P2P traffic during the service period of the rTWT.
2. The method of claim 1 , wherein the subfield is present when a predefined bit is set.
3. The method of claim 1 , wherein the subfield is present when the predefined bit is set in a target wake time (TWT) Information Element (IE).
4. The method of claim 1 , comprising:
configuring, by the first wireless communication device, the subfield in an individual target wake time (iTWT) parameter set field or a broadcast target wake time (bTWT) parameter set field.
5. The method of claim 1 , comprising:
configuring, by the first wireless communication device, the subfield in a broadcast target wake time (bTWT) Info subfield.
6. The method of claim 1 , wherein the subfield comprises a bit that indicates whether the first wireless communication device supports the P2P communication during a service period of the rTWT, or whether the second wireless communication device has P2P traffic to be communicated during the service period of the rTWT.
7. The method of claim 1 , wherein the subfield comprises a bit that indicates use of a channel access procedure for the P2P communication during a service period of the rTWT.
8. The method of claim 7 , wherein the channel access procedure comprises reverse direction protocol or use of a trigger frame sequence.
9. A first wireless communication device comprising:
at least one processor configured to configure a subfield indicating to extend a restricted target wake time (rTWT) for peer-to-peer (P2P) communication; and
a transceiver configured to send a message including the subfield to a second wireless communication device, wherein
the subfield comprises a bit that indicates whether a service period is requested for P2P communication, and
the message causes the second wireless communication device to communicate P2P traffic during the service period of the rTWT.
10. The first wireless communication device of claim 9 , wherein the subfield is present when a predefined bit is set.
11. The first wireless communication device of claim 9 , wherein the subfield is present when the predefined bit is set in a target wake time (TWT) Information Element (IE).
12. The first wireless communication device of claim 9 , wherein the at least one processor is further configured to:
configure the subfield in an individual target wake time (iTWT) parameter set field or a broadcast target wake time (bTWT) parameter set field.
13. The first wireless communication device of claim 9 , wherein the at least one processor is further configured to:
configure the subfield in a broadcast target wake time (bTWT) Info subfield.
14. The first wireless communication device of claim 9 , wherein the subfield comprises a bit that indicates whether the first wireless communication device supports the P2P communication during a service period of the rTWT, or whether the second wireless communication device has P2P traffic to be communicated during the service period of the rTWT.
15. The first wireless communication device of claim 9 , wherein the subfield comprises a bit that indicates use of a channel access procedure for the P2P communication during a service period of the rTWT.
16. The first wireless communication device of claim 15 , wherein the channel access procedure comprises reverse direction protocol or use of a trigger frame sequence.
17. A method comprising:
receiving, by a second wireless communication device from a first wireless communication device, a message including a subfield, wherein the subfield is configured to indicate to extend a restricted target wake time (rTWT) for peer-to-peer (P2P) communication, and the subfield comprises a bit that indicates whether a service period is requested for P2P communication; and
communicating, by the second wireless communication device, P2P traffic during the service period of the rTWT.
18. The method of claim 17 , wherein the subfield is present when a predefined bit is set.
