UE Power Class Reporting for Uplink Duty Cycle Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems lack precise mechanisms for user equipment (UE) to report its power class (PC) status and uplink duty cycle evaluation, leading to inefficiencies in resource allocation and feature configuration by the network due to unknown PC states.
Innovation Solution
A signaling mechanism is established for UE to report the currently used power class and uplink duty cycle evaluation start timing and length, allowing the network to accurately schedule resources and features based on the UE's actual PC state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If UE capability information is transmitted without power class reporting, then signaling overhead is reduced, but network resource allocation accuracy deteriorates
Solution Approach 1:
The UE autonomously determines its power class status and initiates reporting when transitioning to a lower power class, rather than requiring continuous network polling. This self-service approach ensures the network receives accurate power class information without implementing complex centralized monitoring mechanisms.
Solution Approach 2:
The power class reporting is triggered by periodic evaluation of uplink duty cycle metrics. When the duty cycle exceeds a threshold, the UE reports its power class status, creating a periodic feedback mechanism that balances information freshness with signaling overhead reduction.
2Measurement precision
If power class reporting is implemented continuously, then network resource allocation accuracy is improved, but signaling overhead increases
Solution Approach 1:
The UE autonomously determines its power class status and initiates reporting when transitioning to a lower power class, rather than requiring continuous network polling. This self-service approach ensures the network receives accurate power class information without implementing complex centralized monitoring mechanisms.
Solution Approach 2:
Instead of continuous reporting, the system implements partial reporting only when power class transitions occur or when duty cycle thresholds are exceeded. This partial action approach provides sufficient information for network resource allocation while significantly reducing signaling overhead compared to continuous monitoring.
3Measurement precision
If uplink duty cycle evaluation is performed, then power class determination accuracy is improved, but processing complexity increases
Solution Approach 1:
The UE autonomously calculates its own uplink duty cycle based on configured parameters and transmission patterns, eliminating the need for complex network-side measurement and evaluation mechanisms. This self-service approach simplifies the overall system architecture while maintaining measurement precision.
Solution Approach 2:
The network pre-configures duty cycle evaluation parameters and thresholds to the UE before uplink transmissions begin. This preliminary configuration allows the UE to perform simple threshold comparisons rather than complex real-time analysis, reducing processing complexity while maintaining evaluation accuracy.
