Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing power consumption for devices with wake-up radios, as waking the main radio for monitoring communications can be energy-intensive, and existing solutions do not effectively optimize wake-up radio frame formats for reduced overhead and efficient data transfer.
Innovation Solution
The implementation of a method and apparatus for generating and transmitting wake-up radio (WUR) frames that include a first portion indicating whether the frame is fixed or variable length, allowing for optimized frame body presence and length determination, and utilizing a processor to identify intended receiving devices and transmit WUR frames, which includes a MAC header and a frame check sequence (FCS) type for efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main radio is periodically awakened to monitor communications, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The system segments the radio functionality into two distinct parts: a low-power wake-up radio (WUR) for monitoring communications and a main radio for full communication operations. This segmentation allows the device to use only the minimal necessary radio component for monitoring, significantly reducing energy consumption while maintaining communication reliability.
2Productivity
If WUR frames use variable length formats, then data transfer efficiency is improved, but frame processing complexity increases
Solution Approach 1:
The WUR frame format implements dynamic length adjustment through a length field that can indicate either fixed or variable length frames. This dynamic capability allows the frame structure to adapt to different data transfer requirements, optimizing efficiency while maintaining manageable processing complexity through clear format indication.
3Reliability
If WUR frames include comprehensive headers and check sequences, then communication reliability is improved, but overhead increases
Solution Approach 1:
The system changes the parameter of frame structure by implementing a streamlined WUR frame format with optimized header fields and configurable check sequence options. This allows the frame to include necessary reliability components while minimizing overhead through parameter adjustments in frame length and content.

AI summary
This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for generating wake-up radio (WUR) frames formats and implementing WUR communications between transmitting and receiving wireless devices. A transmitting wireless device may identify one or more intended receiving wireless devices for which to send a WUR frame. The transmitting wireless device may generate the WUR frame, where the WUR frame has a first portion that includes a first field. The first field may indicate whether the WUR frame is a fixed length frame or a variable length frame. The transmitting wireless device may also determine a frame check sequence (FCS) type for use with a WUR frame for transmission. The FCS portion may be capable of being one of a plurality of FCS types. The transmitting wireless device may transmit the WUR frame to the one or more intended receiving wireless devices.
