Solution Overview
Problem
New radio light user equipment (NR light UE) has low real-time communication demands but high requirements for standby duration and efficient power management, particularly in scenarios with small communication data volumes and reduced power consumption needs.
Innovation Solution
A resource configuration method that allows user equipment to report power indication information to a base station, enabling the configuration of coverage compensation resources based on a target maximum power level, ensuring reliable data transmission while optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NR light UE uses higher power levels for data transmission, then transmission reliability is improved, but power consumption increases and standby duration decreases
Solution Approach 1:
The patent implements dynamic power level adjustment by allowing UE to report power indication information and receive coverage compensation resource configurations adapted to different power levels. The system transitions from static power configuration to dynamic adaptation, where power levels and corresponding coverage compensation resources are adjusted based on UE capabilities and transmission requirements, resolving the contradiction between transmission reliability and power consumption.
Solution Approach 2:
The patent changes the power level parameter from a fixed value to a configurable parameter with multiple levels. By introducing power indication information reporting and coverage compensation resource configuration for different power levels, the system enables parameter optimization where UE can select appropriate power levels based on transmission needs, balancing reliability requirements with power consumption constraints.
2Duration of action of moving object
If NR light UE reduces power consumption for extended standby, then standby duration is improved, but transmission reliability deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring coverage compensation resources for different power levels before actual data transmission. When UE reports power indication information indicating a reduced power level, the base station has already prepared appropriate coverage compensation resource configurations, enabling immediate activation without compromising transmission reliability even at lower power consumption levels.
Solution Approach 2:
The patent implements beforehand cushioning by providing coverage compensation resources that compensate for potential transmission reliability losses when using reduced power levels. These pre-configured resources act as a cushion, ensuring that even when UE operates at lower power levels for extended standby, transmission reliability is maintained through the compensatory resources.
3Device complexity
If fixed power levels are used for simplicity, then device complexity is reduced, but adaptability to different power requirements deteriorates
Solution Approach 1:
The patent implements self-service by enabling UE to autonomously report its power indication information and select appropriate power levels based on its capabilities and transmission requirements. The UE serves itself by making intelligent power level selections without requiring complex network-side power configuration management, thus maintaining simplicity while achieving high adaptability to different power requirements.
Solution Approach 2:
The patent achieves universality by creating a power configuration framework that can accommodate multiple power levels and different UE types (including NR light UE). The coverage compensation resource configuration mechanism is universally applicable across different power scenarios, allowing the same system to serve both high-power and low-power requirements without requiring separate configuration systems.
