Wake-up Radio Urgent Data Criterion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent transmission of wake-up frames in wireless communication systems increases power consumption and transmission overhead in electronic devices, as they require radios to transition between lower and higher power modes unnecessarily.
Innovation Solution
Implementing a system where electronic devices exchange and determine wake-up criteria, such as buffered data amounts and urgency levels, to selectively transmit wake-up frames only when necessary, reducing the frequency and number of wake-up frames and optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wake-up frames are transmitted frequently to ensure data delivery, then reliability of data transmission is improved, but power consumption increases
Solution Approach 1:
The patent changes the parameter of wake-up frame transmission from frequent/regular intervals to criterion-based transmission. The access point evaluates urgent-data criteria (buffered data amount, urgency level, traffic type) before transmitting wake-up frames, thereby transmitting only when necessary conditions are met, reducing unnecessary power consumption while maintaining reliable data delivery
Solution Approach 2:
The patent implements a feedback mechanism where the access point monitors buffered data status and urgency levels, then decides whether to transmit wake-up frames based on this feedback. The system continuously evaluates criteria and adjusts transmission behavior accordingly, ensuring reliable delivery only when data is actually waiting, thus avoiding unnecessary power consumption
2Reliability
If wake-up frames are transmitted frequently to ensure data delivery, then reliability of data transmission is improved, but transmission overhead increases
Solution Approach 1:
The patent changes the transmission pattern from frequent/criterion-less to criterion-based transmission. By evaluating parameters such as buffered data amount thresholds and urgency levels before transmission, the system reduces the quantity of wake-up frames transmitted while ensuring reliability is maintained for actual data delivery scenarios
3Speed
If radio transitions between lower-power and higher-power modes frequently, then responsiveness to data is improved, but power consumption increases
Solution Approach 1:
The patent changes the radio power mode transition from frequent/criterion-less to criterion-based transitions. The access point evaluates urgent-data criteria before triggering wake-up frames, which in turn trigger radio mode transitions. This ensures transitions occur only when necessary data delivery conditions are met, maintaining responsiveness while reducing unnecessary power consumption from frequent mode switching

AI summary
An interface circuit in an electronic device (such as an access point) may receive a wake-up-radio (WUR)-setup request associated with a recipient electronic device, where the WUR-setup request specifies one or more proposed data criteria or wake-up criteria that indicate when a wake-up frame is to be transmitted to the recipient electronic device. In response, the electronic device may determine one or more data criteria (or wake-up criteria) for use based at least in part on the one or more proposed data criteria. Then, the interface circuit may provide a WUR-setup response intended for the recipient electronic device, where the WUR-setup response indicates acceptance of the one or more proposed data criteria for use as the one or more data criteria or a proposed modification of at least one of the one or more proposed data criteria.
