Solution Overview

Problem

Existing wireless communication systems face challenges in managing signal interference, particularly in full-duplex (FD) modes, where passive-based techniques are insufficient, and adaptive-based methods rely on inaccurate self-interference and cross-link interference measurements.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If passive-based interference management techniques are used in full-duplex modes, then system complexity is reduced, but interference measurement accuracy deteriorates

Engineering Contradiction:

Improvesystem complexityVSAvoidinterference measurement accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the uplink transmission resources into multiple patterns with different muting configurations. Each pattern corresponds to specific time-frequency resources that can be selectively muted to enable accurate interference measurements while maintaining overall system functionality. This segmentation allows the system to achieve accurate measurements without requiring complete system redesign.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic resource muting where the network can configure and switch between different muting patterns based on current interference conditions and measurement requirements. The muting patterns are dynamically activated or deactivated to enable accurate interference measurements at specific times while maintaining normal operations at other times, thus achieving measurement accuracy without permanent system complexity increase.

Inventive Principle:

Principle #15Dynamics

2Measurement precision

If uplink resource muting patterns are implemented to reduce interference, then interference measurement accuracy improves, but configuration overhead increases

Engineering Contradiction:

Improveinterference measurement accuracyVSAvoidconfiguration overhead

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The patent applies partial muting action where only specific time-frequency resources are muted according to configured patterns, rather than muting all uplink resources. This partial approach enables sufficient interference measurement accuracy while minimizing the impact on overall transmission capacity and reducing the extent of configuration required compared to complete muting schemes.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent implements periodic muting patterns where resources are muted at regular intervals according to configured periods. This periodic structure allows the system to achieve measurement accuracy through repeated measurement opportunities while using compact configuration parameters (period, offset, pattern type) that minimize configuration overhead compared to arbitrary muting schedules.

Inventive Principle:

Principle #19Periodic action

3Object-affected harmful factors

If detailed muting pattern configurations are used, then interference reduction effectiveness improves, but system flexibility decreases

Engineering Contradiction:

Improvesignal interferenceVSAvoidsystem flexibility

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent designs muting patterns with universal applicability where a single configuration framework supports multiple pattern types (time-domain, frequency-domain, comb patterns) and multiple activation scenarios. The same configuration mechanism can serve different interference measurement purposes and adapt to various full-duplex operation modes, thus achieving effective interference reduction while maintaining system flexibility through multi-functionality.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent achieves flexible interference management by allowing dynamic changes in muting pattern parameters (period, offset, pattern type, resource allocation) without changing the underlying system architecture. The network can adjust these parameters to adapt to different interference conditions, traffic patterns, and measurement requirements, thus maintaining system flexibility while achieving effective interference reduction through parameter optimization.

Inventive Principle:

Principle #35Parameter changes
