Coverage-Based Paging Mechanism for Adaptive Repetition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems waste resources by transmitting paging messages for a fixed maximum number of repetitions regardless of the user equipment's coverage level, leading to inefficiencies in energy consumption and resource utilization.
Innovation Solution
Implement a coverage level-based paging scheme where user devices report their coverage level capabilities, and network nodes adjust paging message repetitions accordingly, optimizing resource use based on individual device needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging messages are transmitted for a fixed maximum number of repetitions regardless of user equipment coverage level, then all user devices can reliably receive paging messages, but network resources are wasted on devices that do not require maximum repetitions
Solution Approach 1:
The patent applies local quality by differentiating paging message transmission parameters based on the specific coverage level of each user device. Instead of using a uniform maximum number of repetitions for all devices, the system transmits paging messages with repetition counts tailored to each device's coverage characteristics, thereby optimizing resource usage while maintaining reliable delivery for each device type
Solution Approach 2:
The patent implements dynamics by making the paging message repetition count adaptive rather than static. The system dynamically adjusts the number of repetitions based on real-time coverage level information reported by user devices, allowing the network to respond to changing conditions and device capabilities without requiring manual reconfiguration
2Adaptability or versatility
If paging messages are transmitted with maximum repetitions for all user devices, then coverage level requirements are met for all devices, but energy consumption and resource utilization efficiency deteriorate
Solution Approach 1:
The system applies local quality by customizing paging message transmission parameters to match the specific coverage level requirements of each user device. Devices with better coverage receive fewer repetitions while devices with poorer coverage receive more repetitions, ensuring each device consumes only the energy necessary for reliable reception rather than all devices receiving maximum repetitions
Solution Approach 2:
The patent utilizes parameter changes by modifying the paging message repetition count based on coverage level conditions. The system changes this transmission parameter dynamically according to device-specific coverage characteristics, allowing optimization of energy consumption while maintaining adaptability to various coverage scenarios
3Device complexity
If a uniform paging scheme is used for all user devices, then system complexity is reduced, but resource utilization efficiency decreases due to unnecessary transmissions
Solution Approach 1:
The patent applies segmentation by dividing the user device population into different coverage level groups and applying different paging transmission parameters to each group. This segmentation allows the system to maintain relatively simple procedures within each group while achieving overall resource optimization across the diverse device population
Solution Approach 2:
The system implements feedback by having user devices report their coverage level capabilities to the network, which then uses this information to determine appropriate paging message repetition counts. This feedback mechanism enables automatic optimization of resource utilization without requiring complex manual configuration or trial-and-error approaches

AI summary
Methods, apparatus, and systems for a paging scheme based on a coverage level are disclosed. In one example aspect, the method includes receiving, by a first communication node, assistant information for a first paging scheme from a third communication node and transmitting one or more paging messages to a second communication node based on a paging scheme selected between the first paging scheme and a second paging scheme according to the assistant information.
