Paging Parameter Configuration for IoT UE Energy Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IoT protocols, such as NB-IoT and eMTC, waste downlink resources and increase power consumption in UEs due to excessive repetitions of paging signals, especially in smaller coverage areas, without effective energy-saving solutions.
Innovation Solution
Configuring paging parameters based on UE categories, including configuration information for scheduling paging and downlink carrier information, to optimize resource usage and reduce power consumption by adjusting the number of repetitions and resource allocation according to the UE's coverage area and power level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the number of repetitions of paging signals is increased to enhance coverage area, then the paging coverage area is improved, but the downlink resource consumption increases
Solution Approach 1:
The patent applies local quality by differentiating paging parameter configurations based on UE categories. Different UE categories (e.g., CE Mode A, CE Mode B, BL UEs) are assigned different numbers of repetitions and paging occasion configurations according to their specific coverage requirements. This ensures that resources are allocated locally and efficiently rather than uniformly across all UEs, resolving the contradiction between coverage area and resource consumption.
2Area of stationary object
If the number of repetitions of paging signals is increased to enhance coverage area, then the paging coverage area is improved, but the power consumption of UE increases
Solution Approach 1:
The patent implements local quality by tailoring paging parameters to specific UE categories. UEs with smaller coverage requirements (e.g., BL UEs, CE Mode A) are configured with fewer repetitions, while UEs requiring extended coverage (CE Mode B) receive higher repetition counts. This localized adaptation ensures each UE consumes power appropriately for its actual coverage needs rather than uniformly across all devices.
Solution Approach 2:
The patent introduces dynamic adaptability by allowing the network to adjust paging parameters based on real-time UE category identification. The system can dynamically configure different paging occasions, repetition numbers, and monitoring durations according to the identified UE category, enabling flexible power management that adapts to varying coverage requirements rather than using fixed configurations.
3Area of stationary object
If the maximum number of repetitions is configured according to maximum cell coverage area, then the coverage area is ensured, but the downlink resources are wasted for UEs with small coverage area
Solution Approach 1:
The patent resolves this contradiction by implementing local quality through category-specific paging configurations. Instead of uniformly applying maximum repetition counts to all UEs, the system configures appropriate repetition numbers for each UE category. This ensures that UEs with small coverage areas do not waste resources on excessive repetitions, while UEs requiring extended coverage receive sufficient repetitions to maintain connectivity.
4Device complexity
If uniform paging parameters are used for all UEs, then the implementation is simple, but the energy saving performance is insufficient
Solution Approach 1:
The patent applies parameter changes by introducing UE category-based differentiation in paging parameters. The system modifies key parameters such as the number of repetitions, paging occasion timing, and monitoring duration according to identified UE categories. This parameter adaptation enables significant energy saving improvements while maintaining manageable implementation complexity through automated category detection and configuration.
