Solution Overview

Problem

The assessment of radio link quality in wireless communication systems is a key issue, particularly in diverse application scenarios, and existing methods do not efficiently adapt to changes in environment and scenario requirements, leading to potential inefficiencies and increased hardware complexity.

Innovation Solution

A method involving the configuration of RS resource pools for BWP based on TCI states of CORESET, with signaling under the RRC layer for assessing radio link quality, and triggering beam failure recovery when quality thresholds are met, allowing rapid adaptation to environmental changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing methods are used for radio link quality assessment, then the system can maintain basic functionality, but the system cannot efficiently adapt to changes in environment and scenario requirements, leading to increased hardware complexity

Engineering Contradiction:
ImproveAdaptability to environmental changesVSAvoidHardware complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic adaptation by allowing the system to switch between different RS resource pools based on environmental conditions and scenario requirements. The network can dynamically configure and switch between first RS resource pools (for initial assessment) and second RS resource pools (for adapted assessment), enabling the system to respond to changing conditions without requiring multiple fixed hardware configurations for different scenarios.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent creates a universal radio link quality assessment mechanism that can handle multiple application scenarios (uplink, downlink, sidelink, vehicle networking) through a unified framework. The same assessment architecture supports different RS resource pools and assessment methods, allowing one hardware system to perform multiple functions across diverse scenarios without requiring scenario-specific hardware modifications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Speed

If existing methods are used for radio link quality assessment, then the system can operate with current hardware, but the adjustment speed of RS resources is slow, reducing system efficiency

Engineering Contradiction:
ImproveAdjustment speed of RS resourcesVSAvoidSystem efficiency
Core Design Contradiction:
SpeedVSProductivity

Solution Approach 1:

The patent implements preliminary action by pre-configuring multiple RS resource pools (first and second pools) with different characteristics and purposes. The network can pre-prepare appropriate resource pools for different scenarios, so when environmental changes occur, the system can quickly switch to the pre-configured appropriate pool rather than creating resources from scratch, thereby increasing adjustment speed while maintaining system efficiency.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If scenario-specific solutions are implemented for different application scenarios, then each scenario can be optimized, but hardware complexity and costs increase

Engineering Contradiction:
ImproveScenario-specific optimizationVSAvoidHardware complexity and costs
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal radio link quality assessment framework that serves multiple application scenarios (uplink, downlink, sidelink, vehicle networking) through a single standardized interface. The network can configure different RS resource pools with scenario-appropriate parameters, but the underlying hardware and assessment architecture remain unified, allowing scenario-specific optimization without requiring separate hardware systems for each application.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent achieves scenario-specific optimization through parameter changes rather than structural changes. Different scenarios are supported by configuring different parameters (RS resource pool characteristics, assessment thresholds, TCI state associations) within the same hardware framework, allowing each scenario to be optimized for its specific requirements while sharing the same physical infrastructure.

Inventive Principle:
Principle #35Parameter changes
