- Appl. No: 14/486887
- Application Filed: September 15, 2014
- Assignees: QUALCOMM Incorporated (San Diego, CA, US)
- Claim: 1. An apparatus for wireless communications, comprising: a processing system configured to: generate a frame comprising timing information for a target wake time (TWT) and an identification of the TWT to which the timing information applies; and an interface configured to output the frame for transmission, wherein the frame is output for transmission outside a previously indicated service period for the TWT identified by the identification.
- Claim: 2. The apparatus of claim 1 , wherein the identification is provided via one or more bits of at least one of an address field, a timestamp field, or a field that carries timing information for a TWT in the frame.
- Claim: 3. The apparatus of claim 1 , wherein the frame comprises a control response frame.
- Claim: 4. The apparatus of claim 3 , wherein the control response frame comprises a TWT Acknowledgment (TACK) frame, a Short TWT Acknowledgment (STACK) frame, or a Block Acknowledgment TWT (BAT) frame.
- Claim: 5. The apparatus of claim 3 , wherein the identification is provided via a field of the control response frame, wherein the field is dependent, at least in part, on a type of the control response frame.
- Claim: 6. The apparatus of claim 3 , wherein the identification is provided in a TWT Flow Identifier subfield included in an A 1 field in the control response frame.
- Claim: 7. The apparatus of claim 2 , wherein the size of the field that carries the identification is at least 3 bits.
- Claim: 8. A method for wireless communications, comprising: generating a frame comprising timing information for a target wake time (TWT) and an identification of the TWT to which the timing information applies; and outputting the frame for transmission, wherein the frame is output for transmission outside a previously indicated service period for the TWT identified by the identification.
- Claim: 9. The method of claim 8 , wherein the identification is provided via one or more bits of at least one of an address field, a timestamp field, or a field that carries timing information for a TWT in the frame.
- Claim: 10. The method of claim 8 , wherein the frame comprises a control response frame.
- Claim: 11. The method of claim 10 , wherein the control response frame comprises a TWT Acknowledgment (TACK) frame, a Short TWT Acknowledgment (STACK) frame, or a Block Acknowledgment TWT (BAT) frame.
- Claim: 12. The method of claim 10 , wherein the identification is provided via a field of the control response frame, wherein the field is dependent, at least in part, on a type of the control response frame.
- Claim: 13. The method of claim 10 wherein the identification is provided in a TWT Flow Identifier subfield included in an A 1 field in the control response frame.
- Claim: 14. An apparatus for wireless communications, comprising: an interface configured to receive a frame; and a processing system configured to: obtain, from the frame, timing information for a target wake time (TWT) and an identification of the TWT to which the timing information applies, and update a wakeup period for the identified TWT based on the timing information obtained from the frame, wherein the frame is received outside a previously indicated service period for the TWT identified by the identification.
- Claim: 15. The apparatus of claim 14 , wherein the processing system is configured to obtain the identification via one or more bits of at least one of an address field, a timestamp field, or a field that carries timing information for a TWT in the frame.
- Claim: 16. The apparatus of claim 14 , wherein the frame comprises a control response frame.
- Claim: 17. The apparatus of claim 16 , wherein the control response frame comprises a TWT Acknowledgment (TACK) frame, a Short TWT Acknowledgment (STACK), or a Block Acknowledgment TWT (BAT) frame.
- Claim: 18. The apparatus of claim 16 , wherein the processing system is configured to obtain the identification via a field of the control response frame, wherein the field is dependent, at least in part, on a type of the control response frame.
- Claim: 19. The apparatus of claim 16 , wherein the processing system is configured to obtain the identification in a TWT Flow Identifier subfield included in an A 1 field in the control response frame.
- Claim: 20. The apparatus of claim 15 , wherein the size of the field that carries the identification is at least 3 bits.
- Claim: 21. A method for wireless communications, comprising: receiving a frame; obtaining, from the frame, timing information for a target wake time (TWT) and an identification of the TWT to which the timing information applies; and updating a wakeup period for the identified TWT based on the timing information obtained from the frame, wherein the frame is received outside a previously indicated service period for the TWT identified by the identification.
- Claim: 22. The method of claim 21 , wherein the identification is obtained via one or more bits of at least one of an address field, a timestamp field, or a field that carries timing information for a TWT in the frame.
- Claim: 23. The method of claim 21 , wherein the frame comprises a control response frame.
- Claim: 24. The method of claim 23 , wherein the control response frame comprises a TWT Acknowledgment (TACK) frame, a Short TWT Acknowledgment (STACK), or a Block Acknowledgment TWT (BAT) frame.
- Claim: 25. The method of claim 23 , wherein the identification is obtained via a field of the control response frame, wherein the field is dependent, at least in part, on a type of the control response frame.
- Claim: 26. The method of claim 23 , wherein the identification is obtained in a TWT Flow Identifier subfield included in an A 1 field in the control response frame.
- Claim: 27. The apparatus of claim 1 , further comprising an antenna, wherein the interface is configured to transmit the frame via the antenna, and, wherein the apparatus is configured as an access point.
- Claim: 28. The apparatus of claim 14 , further comprising an antenna, wherein the interface is configured to receive the frame via the antenna, and wherein the apparatus is configured as a user terminal.
