Solution Overview

Problem

Wireless user equipment (UE) experiences co-existence issues due to interference from multiple networks and base stations, leading to inefficiencies in interference mitigation, battery conservation, and transmission processes, as existing solutions fail to effectively manage these challenges using static signal quality and base station parameter thresholds.

Innovation Solution

A method and system where the UE receives base station parameters and signal quality metrics to dynamically select operating modes that implement interference mitigation techniques, such as PDCCH-Only, CRS-IM, and CRS-IC, using variable thresholds based on scheduling rate and signal quality parameters to optimize co-existence management.

VSEngineering Contradiction Analysis

1Reliability

If multiple interference mitigation techniques are implemented simultaneously, then interference mitigation capability is improved, but device complexity and co-existence issues worsen

Engineering Contradiction:

Improveinterference mitigation capabilityVSAvoidco-existence management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic selection of interference mitigation techniques based on real-time signal quality measurements and base station parameter evaluations. The UE dynamically switches between different mitigation techniques (such as PDCCH-Only, CRS-IM, CRS-IC) rather than implementing all techniques simultaneously, thereby maintaining effective interference mitigation while reducing system complexity and avoiding co-existence issues between conflicting techniques

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by evaluating signal quality metrics and base station parameters to determine which mitigation technique to apply. By adjusting the selection of mitigation techniques based on parameter thresholds and signal conditions, the system achieves effective interference mitigation without the complexity of running multiple techniques in parallel

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If static thresholds are used for signal quality and base station parameters, then device complexity is reduced, but adaptability to different network conditions worsens

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent employs dynamic threshold adjustment based on real-time signal quality measurements and base station parameter evaluations. Instead of using fixed static thresholds, the system adapts its decision criteria according to current network conditions, enabling effective operation across diverse network environments while maintaining manageable device complexity through automated dynamic adaptation

Inventive Principle:

Solution Approach 1:

The patent extracts and evaluates specific signal quality metrics and base station parameters from multiple network connections to determine the optimal mitigation technique. By selectively processing relevant parameters from each network connection and applying appropriate mitigation techniques, the system maintains multi-network connectivity capability while managing interference through targeted extraction and processing of critical signal information

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary evaluation mechanism that assesses signal quality and base station parameters before selecting mitigation techniques. This intermediary layer mediates between multiple network connections and the interference mitigation mechanisms, enabling the UE to maintain connectivity to multiple networks while systematically managing interference through parameter-based decision making

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Method and apparatus for co-existence management between mitigation techniques where a user device (“UE”) is connected to a base station (“BS”) of a network. The UE may receive a first value of a BS parameter from the BS and may determine a second value of a signal quality parameter corresponding to a signal received by the UE from the BS. The UE may then select an operating mode for the UE based on the first value and the second value, where the operating mode comprises implementing at least one interference mitigation technique.
