Cross-Frequency Sensing by Proxy for Sub-7 and DMG Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing WLAN sensing technologies do not effectively address how an SBP initiator supporting a Sub-7 frequency band can request an SBP responder supporting a DMG frequency band for sensing measurements when high-precision requirements are needed, and vice versa, especially when devices operating in the same frequency band are unavailable.
Innovation Solution
A method and communication device that enable cross-frequency band sensing by proxy (SBP), allowing an SBP initiator to request an SBP responder to perform sensing measurements in a proxy mode across different frequency bands, including scenarios where a low-frequency band device requests a high-frequency band measurement, a high-frequency band device requests a low-frequency band measurement, or simultaneous measurements in both bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an SBP initiator supporting Sub-7 frequency band requests sensing measurement from an SBP responder supporting DMG frequency band, then cross-frequency band sensing capability is improved, but existing WLAN sensing technology is insufficient to address this scenario
Solution Approach 1:
The patent introduces a proxy mode mechanism where the SBP responder acts as an intermediary to perform sensing measurements on behalf of the SBP initiator. When the initiator supports Sub-7 band but needs DMG band measurements, the responder in proxy mode enables this cross-band operation, resolving the adaptability-reliability contradiction by providing both cross-frequency capability and maintained measurement reliability through proper protocol design
Solution Approach 2:
The patent makes the SBP responder multi-functional by enabling it to operate in both normal mode and proxy mode. In proxy mode, the responder can perform sensing measurements for initiators of different frequency bands (Sub-7 or DMG), making the system universally applicable across frequency band combinations while maintaining reliable sensing through standardized measurement procedures
2Adaptability or versatility
If devices perform sensing measurements in the same frequency band, then technology implementation is simple, but application scope is limited when devices operating in the same frequency band are unavailable
Solution Approach 1:
The proxy mode mechanism serves as an intermediary layer that enables devices to perform cross-frequency band sensing without requiring direct peer-to-peer connections across different frequency bands. This simplifies the system architecture by introducing a standardized proxy interaction model rather than requiring complex direct coordination between Sub-7 and DMG devices
Solution Approach 2:
The patent segments the sensing functionality by introducing distinct operational modes (normal mode and proxy mode) for the SBP responder. This segmentation allows the system to handle different frequency band combinations through standardized interfaces, expanding application scope while managing complexity through modular design

AI summary
Provided is a method for sensing by proxy (SBP). The method is applicable to an SBP initiator supporting a first frequency band and the method includes: transmitting an SBP Request frame to an SBP responder, wherein the SBP Request frame is used to request the SBP responder to perform sensing measurement of a second frequency band in a proxy mode, or request the SBP responder to perform sensing measurement of the first frequency band and the second frequency band in a proxy mode; and receiving an SBP Response frame from the SBP responder, wherein the SBP responder is a device that supports both the first frequency band and the second frequency band.
