Solution Overview

Problem

Current wireless communication systems face inefficiencies in signal transmission and reception, particularly in managing beam resources for user equipment (UE) with low mobility, leading to suboptimal paging performance due to inadequate beam selection and reporting mechanisms.

Innovation Solution

The proposed method involves the UE reporting its mobility state and measuring the quality of specific beam resources, allowing it to switch to new beam resources when the measurement quality falls below a threshold, and the base station configures paging transmissions based on the selected beam indices, ensuring efficient signal reception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the UE uses fixed beam resources for paging reception, then the device complexity is reduced, but the paging performance deteriorates due to inadequate beam selection for low mobility UEs

Engineering Contradiction:
Improvebeam resource management complexityVSAvoidpaging reception reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent implements dynamic beam resource selection for paging reception by allowing the UE to switch between SSB-based and CSI-RS-based beam resources based on mobility state and measurement quality. The UE dynamically selects beam resources for paging reception based on current channel conditions and mobility characteristics, transitioning from fixed to adaptive beam management.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of beam resource type from static to variable by introducing mobility state-dependent beam selection. The system adjusts beam resource parameters (SSB indices or CSI-RS resource indicators) based on UE mobility state and measured quality metrics, enabling adaptation to different operational conditions.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the UE continuously monitors and reports beam quality measurements, then the paging performance is improved through accurate beam selection, but the energy consumption increases

Engineering Contradiction:
Improvebeam selection accuracyVSAvoidUE energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial monitoring by having the UE perform beam quality measurements only when necessary based on mobility state and triggering conditions. Instead of continuous monitoring, the UE measures beam quality (RSRP/RSRQ) selectively and reports only when measurements indicate potential beam changes or according to configured reporting triggers, reducing unnecessary energy expenditure.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent implements feedback mechanisms where the UE reports beam quality measurements and mobility state information to the network, which then adjusts beam resource configurations accordingly. This feedback loop enables the network to optimize beam selection based on actual UE conditions, improving paging reception while allowing the UE to conserve energy by not continuously monitoring.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If the network configures multiple beam resources for paging, then the adaptability to different mobility states is improved, but the device complexity increases due to additional configuration management

Engineering Contradiction:
Improvebeam resource adaptabilityVSAvoidconfiguration management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates universal beam resource configurations that serve multiple functions and mobility states. The same CSI-RS resources can be used for both beam management and paging reception, and the configuration framework supports both SSB-based and CSI-RS-based approaches within a unified structure, reducing the need for separate dedicated configurations for each scenario.

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