Solution Overview

Problem

Current mobile communication systems face challenges in triggering joint channel estimation effectively when user equipment (UE) meets specific constraint conditions, affecting channel coverage quality and range.

Innovation Solution

A method and device for UE to send messages to network devices indicating whether it meets predetermined conditions for joint channel estimation, allowing the network device to determine whether to perform joint channel estimation, with options for periodic or non-periodic messaging and explicit or implicit signaling methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If joint channel estimation is performed to enhance channel coverage quality and range, then channel coverage quality and range are improved, but the complexity of triggering the estimation process increases

Engineering Contradiction:
Improvechannel coverage qualityVSAvoidtriggering process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The UE autonomously determines whether to trigger joint channel estimation by evaluating local constraint conditions (such as channel state, signal strength, or interference levels) without requiring continuous network control. This self-service approach reduces triggering complexity while maintaining reliable channel coverage enhancement.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-configures constraint conditions and triggering thresholds before actual estimation is needed. By preparing these criteria in advance, the UE can quickly determine when to trigger joint channel estimation without complex real-time decision-making, thus reducing triggering process complexity.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If UE sends messages to network device to trigger joint channel estimation, then timely estimation is enabled, but signaling overhead increases

Engineering Contradiction:
Improvetriggering response timeVSAvoidsignaling overhead
Core Design Contradiction:
Loss of timeVSLoss of energy

Solution Approach 1:

Instead of continuous or frequent messaging, the UE employs periodic or event-driven message sending. The UE only transmits triggering messages when specific constraint conditions are met, reducing signaling overhead while ensuring timely estimation activation when needed.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The triggering message contains only essential information about whether the UE meets the predetermined conditions, extracting only the critical decision-making data from the full UE state. This minimizes signaling overhead while maintaining timely triggering capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If UE sends messages periodically or non-periodically, then triggering reliability is improved, but signaling overhead varies

Engineering Contradiction:
Improvetriggering reliabilityVSAvoidsignaling overhead
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The messaging mechanism dynamically adjusts between periodic and non-periodic transmission based on system conditions. When channel conditions are stable, periodic messaging maintains reliability with minimal overhead; when conditions change rapidly, non-periodic event-driven messaging ensures reliable triggering without unnecessary signaling.

Inventive Principle:
Principle #15Dynamics
