UWB Positioning Response Merging for Lower Power and Interference

Solution Overview

Problem

The increase in the number of external electronic devices measuring a position of an electronic device leads to increased power consumption and signal interference due to the transmission of multiple response messages, degrading the quality of the signal.

Innovation Solution

An electronic device is equipped with both a first communication circuit for UWB and a second communication circuit for D2D communication, allowing it to selectively activate the UWB circuit based on designated conditions and transmit a single response message after receiving polling messages within a specified time frame, reducing power consumption and signal interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of response messages transmitting to external electronic devices increases to support position measurement by multiple devices, then the position measurement capability is improved, but power consumption increases and signal interference increases degrading signal quality

Engineering Contradiction:

Improveposition measurement capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent merges multiple response messages into a single aggregated response message that contains position measurement data for multiple external electronic devices. Instead of transmitting separate response messages to each device, the system combines all position measurement information into one message, thereby reducing the number of transmissions, lowering power consumption, and minimizing signal interference while maintaining the ability to support position measurement by multiple devices.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If the number of response messages transmitting to external electronic devices increases to support position measurement by multiple devices, then the position measurement capability is improved, but signal interference increases degrading signal quality
