Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal capability reporting methods cannot accurately describe the uplink duty cycle capability of each antenna panel, leading to inefficient power and resource scheduling, and potential exceedance of Maximum Permitted Emission (MPE) limits.
Innovation Solution
A terminal capability reporting method that includes reporting a target terminal capability to a base station, which at least includes a maximum uplink duty cycle value corresponding to each antenna panel, allowing for more precise power and resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the terminal reports a unified maximum uplink duty cycle value without antenna panel differentiation, then the reporting mechanism is simple, but the accuracy of describing uplink duty cycle capability for each antenna panel deteriorates
Solution Approach 1:
The patent segments the unified duty cycle capability into per-antenna-panel capability values. Each antenna panel is assigned its own maximum uplink duty cycle value (maxUplinkDutyCycle-panel[i]), allowing independent reporting and management of duty cycle characteristics for each panel, thereby improving measurement precision without significantly increasing reporting complexity
Solution Approach 2:
The patent applies local quality by recognizing that different antenna panels may have different duty cycle capabilities due to varying MPE limits, radiation patterns, or thermal characteristics. Each panel is assigned its specific capability value rather than using a uniform value for all panels, enabling accurate local characterization of each antenna panel's duty cycle performance
2Productivity
If the terminal uses inaccurate uplink duty cycle capability information, then the scheduling process is simple, but the stability and efficiency of uplink transmission deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the terminal reports its per-antenna-panel duty cycle capability values to the network side, and the network uses this feedback information to perform accurate power and resource scheduling. This feedback loop ensures that scheduling decisions are based on actual terminal capabilities, improving both transmission stability and efficiency
Solution Approach 2:
The patent enables dynamic scheduling adjustments based on the reported duty cycle capability values. The network can dynamically allocate uplink resources and adjust power levels according to the specific capability characteristics of each antenna panel, allowing the system to adapt to varying transmission conditions and optimize performance in real-time
3Object-affected harmful factors
If the terminal does not report per-antenna-panel duty cycle capability, then the capability reporting is simple, but the compliance with MPE limits cannot be ensured
Solution Approach 1:
The patent segments the MPE compliance check into per-antenna-panel level. Each antenna panel reports its specific maximum uplink duty cycle value, allowing the network to verify MPE compliance for each panel independently. This segmentation enables precise control and verification of electromagnetic radiation exposure limits without requiring overly complex reporting structures
Solution Approach 2:
The patent replaces complex mechanical or procedural compliance verification methods with a streamlined information reporting and scheduling approach. By having the terminal report its capability values and the network perform scheduling based on these values, the system achieves MPE compliance through intelligent resource management rather than complex control mechanisms
