Solution Overview

Problem

Existing uplink transmission power management techniques can negatively impact critical uplink signals, leading to performance degradation in NR systems due to overlapping UL gaps with critical UL signals.

Innovation Solution

A method for a radio device to determine the timing relation between uplink gaps and critical uplink signals, allowing selective use of UL gaps for uplink transmit power management, thereby prioritizing critical signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If UL gaps are configured for uplink transmit power management, then power management capability is improved, but critical uplink signal transmission is degraded

Engineering Contradiction:
Improvepower management capabilityVSAvoidcritical uplink signal transmission
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements dynamic prioritization where the radio device dynamically determines timing relations between UL gaps and critical UL signals, and selectively cancels or uses UL gaps based on real-time signal criticality. This dynamic adaptation resolves the contradiction by making the power management system flexible enough to accommodate critical signals when they occur, rather than rigidly following pre-configured gap patterns.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs feedback mechanisms where the radio device monitors the timing of critical UL signals and adjusts UL gap utilization accordingly. By determining timing relations and selectively canceling gaps when critical signals are detected, the system uses feedback to prevent harmful interference to critical transmissions while maintaining power management benefits during non-critical periods.

Inventive Principle:
Principle #23Feedback

2Object-affected harmful factors

If UL gaps are used for body proximity sensing and power management, then exposure safety is improved, but system performance is degraded

Engineering Contradiction:
Improveexposure safetyVSAvoidsystem performance
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent dynamically adjusts the application of UL gaps based on the detected timing relation with critical signals. When critical signals are detected during configured gap periods, the device dynamically decides to cancel the gap and transmit the critical signal instead. This dynamic behavior maintains exposure safety during non-critical periods while preserving system performance during critical signal occasions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent converts the potential harm of missed power management opportunities (when gaps are canceled for critical signals) into benefit by prioritizing critical signal transmission. The system recognizes that occasionally sacrificing power management timing is acceptable when critical signals require transmission, thus converting what could be seen as a loss into a necessary protective measure for system integrity.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A technique for an uplink transmit power management, UTPM, procedure is described. As to a method aspect of the technique performed by a radio device a timing relation between a timing of at least one uplink gap, UL gap (602), for the UTPM procedure and a timing of at least one UL signal (604) belonging to a procedure in a first set of procedures, PS1, is determined. The at least one UL gap (602) is selectively used for the UTPM procedure depending on the determined timing relation.
