Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G communication systems face challenges in efficiently managing UE power consumption and resource allocation for paging and system information acquisition, particularly in high-frequency bands, due to the increased demand for high-speed data services and diverse use cases with varying requirements.
Innovation Solution
The proposed solution involves UE-based and network-based paging grouping methods using multiple P-RNTIs and UE IDs to optimize monitoring occasions and reduce unnecessary power consumption by aligning paging arrival rates, allowing for more efficient resource utilization and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UEs monitor paging continuously to ensure reliable reception, then paging reliability is improved, but UE power consumption increases
Solution Approach 1:
The patent segments UEs into different paging groups based on their paging arrival rates. Each group is assigned specific monitoring occasions, allowing UEs to sleep during non-monitored periods and wake only when needed, thus reducing power consumption while maintaining reliable paging reception for each group.
Solution Approach 2:
The patent changes the monitoring parameters by introducing group-specific monitoring occasions and associating different P-RNTIs with different paging groups. This allows UEs to adjust their monitoring behavior according to their group assignment, optimizing the balance between reliability and power consumption.
2Loss of time
If UEs monitor paging frequently to capture paging messages timely, then paging response time is improved, but system resource allocation complexity increases
Solution Approach 1:
By segmenting UEs into paging groups with different monitoring occasions, the system distributes paging responsibilities across multiple time slots and P-RNTIs. This segmentation allows timely paging delivery to each group while simplifying individual UE monitoring requirements compared to universal frequent monitoring.
Solution Approach 2:
The patent implements periodic monitoring occasions for each paging group, where UEs wake up at predetermined intervals specific to their group. This periodic action ensures timely paging reception while reducing overall monitoring frequency compared to continuous monitoring, thereby managing system complexity.
3Use of energy by moving object
If multiple P-RNTIs are used for different paging groups to reduce monitoring overhead, then UE power efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the paging domain into multiple groups, each with its own P-RNTI and monitoring occasions. This segmentation allows UEs to focus monitoring efforts on specific time slots and P-RNTIs relevant to their group, improving power efficiency while limiting the complexity increase to manageable levels through structured organization.
Solution Approach 2:
The patent creates a universal paging framework where multiple P-RNTIs serve different paging groups but follow the same monitoring and reception procedures. This multi-functionality approach improves power efficiency across different UE types while maintaining consistent device complexity through standardized multi-group support.
4Adaptability or versatility
If paging monitoring occasions are increased to serve diverse UE requirements, then system adaptability is improved, but resource allocation overhead increases
Solution Approach 1:
The patent segments the paging resource space into multiple groups with different monitoring occasions and P-RNTI assignments. This segmentation provides adaptability to diverse UE requirements by allowing different monitoring patterns while reducing overall resource overhead through efficient grouping and shared resource utilization across segments.
