Terminal Max Transmit Power Determination via Service-Type Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to extend the transmission distance of uplink signals while minimizing interference to the base station, especially when multiple user equipment (UEs) have different power levels, as they rely on setting limiting powers uniformly across all UEs with the same power level.
Innovation Solution
A method where a terminal receives configuration parameters from a base station, determining its maximum transmit power based on its specific power level and service type, allowing for dynamic adjustment of transmit power limits to extend signal range and reduce interference, even when UEs have different power levels or service types.

Engineering Contradiction Analysis
1Ease of operation
If the base station sets a uniform limiting power for all UEs with the same power level, then the system operation is simplified, but the transmission distance cannot be maximized for UEs with different service types
Solution Approach 1:
The patent segments the limiting power configuration by service type. Instead of applying a uniform limiting power to all UEs with the same power level, the base station now configures different limiting powers for different service types (e.g., eMBB, URLLC, mMTC). This allows each service type to have optimized transmission parameters, extending transmission distance for specific services while maintaining system simplicity through structured segmentation.
Solution Approach 2:
The patent introduces dynamic limiting power configuration based on service type requirements. The base station can adjust limiting powers dynamically according to the specific service type being performed by each UE, rather than using a static uniform limit. This dynamic approach enables transmission distance optimization for different service scenarios while maintaining ease of operation through automated service-type-based management.
2Length of moving object
If the base station sets different limiting powers for multiple UEs with different power levels, then the transmission distance can be optimized for each UE, but the system complexity increases
Solution Approach 1:
The patent applies local quality by tailoring limiting power configuration to each UE's specific service type rather than using a one-size-fits-all approach. Each UE receives a limiting power value optimized for its local service requirements (eMBB, URLLC, or mMTC), enabling transmission distance optimization without requiring complex manual configuration for each individual UE. The service type acts as a local identifier that simplifies the customization process.
Solution Approach 2:
The patent changes the limiting power parameter based on service type classification. By introducing service type as a determining factor for limiting power configuration, the system can optimize transmission distance for different service scenarios. The parameter change is automated based on service type identification, reducing the complexity burden on the network operator while achieving customized power management.
3Length of moving object
If the UE transmits at higher power to extend transmission distance, then the signal reaches farther, but interference to the base station increases
Solution Approach 1:
The patent optimizes the transmit power parameter by configuring service-type-specific limiting powers. For each service type (eMBB, URLLC, mMTC), the base station determines an appropriate limiting power that balances transmission distance extension with interference control. This parameter optimization ensures that UEs transmit at the highest necessary power for their specific service requirements, extending transmission distance while minimizing unnecessary interference to the base station.
