Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a positioning reference signal with large bandwidth is used in cellular positioning systems, then positioning precision is improved, but power consumption increases beyond the constraints of AMP devices

Engineering Contradiction:

Improvepositioning precisionVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent changes the bandwidth parameter of the positioning reference signal from large bandwidth to narrow bandwidth, specifically configuring the bandwidth to be within a first bandwidth range that is smaller than a second bandwidth range. This parameter change enables AMP devices with power constraints to achieve positioning functionality without excessive power consumption.
