PEI Parameter Mapping for Redcap UE Paging Across Initial BWPs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of configuring paging earlier indication (PEI) parameter sets for reduced capability UEs (Redcap UEs) under varying downlink initial bandwidth part (BWP) configurations in wireless communication systems is not adequately addressed, leading to inefficiencies in resource utilization and power consumption.
Innovation Solution
The method involves determining and configuring a specific PEI parameter set for each downlink initial BWP, allowing for individualized configuration based on the type of UE, ensuring that Redcap UEs can efficiently monitor PEI resources by associating the parameter set with the appropriate BWP, thereby optimizing resource allocation and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a unified PEI parameter set configuration is used for all UEs across different BWPs, then system simplicity is maintained, but resource utilization efficiency deteriorates due to unnecessary monitoring by Redcap UEs
Solution Approach 1:
The patent segments the PEI parameter set configuration by associating different PEI parameter sets with different downlink initial BWPs. This allows Redcap UEs to monitor PEI only on their specific BWP rather than all BWPs, improving resource utilization efficiency while maintaining manageable configuration complexity through structured association
Solution Approach 2:
The patent applies local quality by configuring PEI parameters specifically for each BWP type (e.g., first type for normal UEs, second type for Redcap UEs). Each BWP has tailored PEI monitoring configurations matched to its characteristics and target UE type, optimizing performance locally without affecting other BWPs
2Reliability
If Redcap UEs monitor PEI on all downlink initial BWPs, then paging coverage is ensured, but power consumption increases due to continuous monitoring
Solution Approach 1:
The patent divides the monitoring scope by associating Redcap UEs with specific PEI parameter sets tied to their designated downlink initial BWP. This segmentation allows UEs to monitor only relevant PEI occasions on their assigned BWP, ensuring adequate paging coverage for Redcap UEs while dramatically reducing power consumption compared to monitoring all BWPs
Solution Approach 2:
The patent implements partial action by configuring PEI monitoring only on the specific BWP relevant to Redcap UEs rather than all BWPs. This partial monitoring approach provides sufficient paging coverage for the target UE type while avoiding the excessive power consumption of universal monitoring across all BWPs
3Adaptability or versatility
If PEI parameter sets are individually configured for each BWP type, then configuration flexibility is improved, but signaling overhead increases
Solution Approach 1:
The patent segments PEI parameter configurations into distinct sets for different BWP types, allowing flexible adaptation to specific BWP characteristics and UE types. This segmentation achieves high configuration flexibility while managing signaling overhead through structured, type-based organization rather than completely individualized configurations
Solution Approach 2:
The patent applies universality by creating standardized PEI parameter set types (first type for normal UEs, second type for Redcap UEs) that can be applied across multiple BWPs of the same type. This multi-functional approach provides configuration flexibility through type-based adaptation while reducing signaling overhead by reusing standardized parameter sets across multiple BWPs
