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.
Claims13
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,
- wherein the portion and the another portion are both provided in a preamble and header portion of the frame, wherein the wakeup information includes a wakeup waveform,
- wherein the wakeup waveform is defined by one or more associated symbols that comprise a unique data pattern that one or more nodes recognize as being a wakeup waveform, and one or more node identifications, wherein the unique data pattern and the one or more node identifications are separate, distinct groups of one or more associated symbols, and
- wherein the wakeup waveform includes information that is orthogonal or pseudo-orthogonal to information of the portion enabling the one or more nodes to detect the frame, and wherein the wakeup waveform causes a transitioning from a first power state to a second power state at a receiving node,
- the frame further including a body portion.
4 more elements
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 a predefined set of nodes of a plurality of nodes associated with the communication network medium is to transition from a first power state to a second power state,
- wherein the second portion is provided immediately following the first portion,
- wherein the wakeup information includes a wakeup waveform, wherein the wakeup waveform is defined by one or more associated symbols that comprise a unique data pattern that one or more nodes recognize as being a wakeup waveform, and one or more node identifications, wherein the unique data pattern and the one or more node identifications are separate, distinct groups of one or more associated symbols,
- wherein the wakeup waveform includes information that is orthogonal or pseudo-orthogonal to information of the portion enabling the one or more nodes to detect the frame and wherein the wakeup waveform causes a transitioning from a first power state to a second power state at a receiving node.
5 more elements
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 a predefined set of nodes of a plurality of nodes is to transition from a first power state to a second power state, the wakeup information comprising a wakeup waveform, wherein the wakeup waveform is defined by one or more associated symbols that comprise a unique data pattern that one or more nodes recognize as being a wakeup waveform, and one or more node identifications, wherein the unique data pattern and the one or more node identifications are separate, distinct groups of one or more associated symbols, wherein the wakeup waveform includes information that is orthogonal or pseudo-orthogonal to information of the first portion enabling the one or more nodes to detect the frame, and wherein the second portion is received immediately following the first portion;
- and
- transitioning the first power state to the second power state at the node.
