Abstract

Representative implementations of devices and techniques provide an efficient communication that enables nodes in a reduced power consumption state to resume a regular power state (e.g., fully operational) or otherwise another power state (e.g., semi-operational) after processing the communication.

Claims

1. A system, comprising:

a communication network medium; and

at least one node coupled to the medium, the at least one node arranged to communicate, at least in part via the medium, a frame that includes a portion enabling one or more nodes to detect the frame and another portion that includes wakeup information.

2. The system of claim 1, wherein the wakeup information is a wakeup waveform, the wakeup waveform including information that is orthogonal or pseudo-orthogonal to information of the portion enabling the one or more nodes to detect the frame.

3. The system of claim 1, wherein the wakeup information includes a wakeup waveform and one or more node identifications.

4. The system of claim 3, wherein the frame further includes a payload for delivery to one or more nodes linked to the one or more node identifications.

5. The system of claim 1, wherein the wakeup information is a unique wakeup waveform that is linked to only one node or a predefined set of nodes of a plurality of nodes.

6. The system of claim 1, wherein the frame comprises at least a preamble and header portion, at least part of the at least a preamble and header portion to carry the portion enabling one or more nodes to detect the frame.

7. The system of claim 6, wherein the frame further comprises a payload portion, the payload portion to carry the wakeup information.

8. The system of claim 7, wherein the frame comprises only the preamble and header portion and the payload portion to carry the wakeup information.

9. The system of claim 8, wherein the frame is a mobile applications protocol (MAP) physical layer (PHY) frame communication.

10. A node, comprising:

a controller; and

a storage memory coupled to the controller and including instructions to generate at least one communication for communication on a communication network medium when executed by the controller, the at least one communication to include;

a first portion enabling one or more nodes to detect the at least one communication, and

a second portion including wakeup information, the wakeup information to indicate that one or more nodes associated with the communication network medium is to transition from a first power state to a second power state.

11. The node of claim 10, wherein the first power state is a reduced power consumption state and the second power state is a state in which the one or more nodes consume more power than in the reduced power consumption state.

12. The node of claim 10, wherein the at least one communication includes only the first and second portions.

13. The system of claim 10, wherein the at least one communication comprises at least a preamble and header portion and a payload portion, at least part of the at least a preamble and header portion to carry the first portion enabling the one or more nodes to detect the at least one communication and the payload portion to carry the wakeup information.

14. A method, comprising:

receiving, at a node, a frame including a first portion enabling one or more nodes to detect the frame and a second portion including wakeup information, the wakeup information to indicate that one or more nodes is to transition from a first power state to a second power state; and

transitioning the first power state to the second power state at the node.

15. The method of claim 14, wherein the first power state is a reduced power consumption state and the second power state is a state in which the one or more nodes consume more power than in the reduced power consumption state.

16. The method of claim 14, wherein the frame comprises at least a preamble and header portion and a payload portion, at least part of the at least a preamble and header portion to carry the first portion enabling the one or more nodes to detect the at least one communication and the payload portion to carry the wakeup information.

17. The method of claim 14, wherein the wakeup information is a wakeup waveform, the wakeup waveform including information that is orthogonal or pseudo-orthogonal to information of the first portion enabling the one or more nodes to detect the frame.

18. The method of claim 14, wherein the wakeup information includes a wakeup waveform and one or more node identifications.

19. The method of claim 14, wherein the wakeup information is a unique wakeup waveform that is linked to only one node or a predefined set of nodes of a plurality of nodes.
