Paging Early Indication Adaptation for Dynamic Paging Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, user equipment (UEs) face challenges in determining how to update paging early indication (PEI) configurations in response to dynamic updates in paging configurations, leading to inefficiencies in network energy savings and UE power consumption.
Innovation Solution
UEs are equipped to autonomously update PEI configurations based on dynamic updates to paging configurations, using threshold values, predefined mappings, or rules to ensure alignment with the updated paging configurations, thereby optimizing PEI parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If UEs autonomously update PEI configurations based on dynamic paging configuration updates, then network energy savings and UE power efficiency are improved, but device complexity and configuration management complexity increase
Solution Approach 1:
The UE autonomously updates its PEI configuration based on received paging configuration updates without requiring explicit network reconfiguration messages. The UE self-determines whether to apply updates by comparing paging cycle parameters against threshold values and autonomously adjusts PEI parameters accordingly, reducing network signaling overhead and improving energy efficiency
Solution Approach 2:
The patent implements dynamic parameter adjustment where the PEI configuration parameters (such as pei-Periodicity, pei-StartOffset) are automatically modified based on changes in paging configuration parameters (such as pagingCycle, nB). The UE evaluates parameter changes against predefined thresholds and mapping rules to determine appropriate PEI configuration updates
2Stability of the object's composition
If UEs autonomously update PEI configurations using threshold values and mappings, then alignment between PEI and paging configurations is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The system implements a feedback mechanism where the UE monitors paging configuration updates from the network, compares them against stored threshold values and mapping rules, and automatically adjusts PEI configurations accordingly. The network can verify UE behavior through uplink communications, ensuring proper alignment without requiring complex explicit confirmation protocols
Solution Approach 2:
The UE is pre-configured with threshold values, mapping rules, and evaluation criteria before operation. These preliminary configurations enable the UE to autonomously detect and respond to paging configuration changes without requiring real-time network guidance, simplifying the detection process while maintaining proper alignment

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first control message indicating a first paging configuration associated with a first paging cycle and may receive a first paging early indication (PEI) associated with the first paging cycle in accordance with a first PEI parameter set based on the first paging configuration. The UE may determine whether to update the first PEI parameter set for a second PEI associated with a second paging cycle based on updating the first paging configuration. In some cases, the UE may determine not to update the first PEI parameter set and may receive the second PEI in accordance with the first PEI parameter set. In some other cases, the UE may determine to update the first PEI parameter set and may receive the second PEI in accordance with a second PEI parameter set.
