Carrier Aggregation Power Class Reporting for Per-Carrier Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies fail to accurately report the maximum output power of each carrier in a carrier aggregation scenario, leading to inconsistencies and potential errors in power class recording by the base station.
Innovation Solution
A method and device for reporting information based on carrier aggregation that determines a first and second maximum output power for each carrier, and reports the power class corresponding to the second maximum output power of a target carrier to the base station when it exceeds the first, using carrier identification and power class fields in indication information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the terminal device reports only the total power class in the carrier aggregation scenario, then the reporting process is simple, but the base station cannot accurately determine the maximum output power of each individual carrier
Solution Approach 1:
The patent segments the total power class information into individual carrier power class information. Instead of reporting a single aggregate power class value, the terminal device now reports power class information for each carrier separately, allowing the base station to accurately determine the maximum output power of each individual carrier in the carrier aggregation scenario.
Solution Approach 2:
The patent introduces a new dimension to the power class reporting by adding carrier identification fields to the existing power class information. This transforms the reporting from a single-dimensional total power class value to a multi-dimensional structure that includes both carrier identity and corresponding power class, enabling precise tracking of each carrier's power capabilities.
2Measurement precision
If the terminal device reports detailed power class information for each carrier, then the base station can accurately determine maximum output power, but the information transmission overhead increases
Solution Approach 1:
The patent applies preliminary action by having the terminal device determine and prepare the power class information for each carrier before the actual reporting process. The terminal device calculates the maximum output power of each carrier in advance and organizes this information with carrier identification fields, so that when reporting is needed, the information is already structured and ready, reducing processing overhead during the reporting phase.
3Productivity
If the base station uses the total power class to allocate transmitting channels, then the channel allocation process is simple, but the power allocation may not be optimized for each specific carrier
Solution Approach 1:
The patent applies local quality by enabling the base station to allocate power resources specifically tailored to each carrier's characteristics. With detailed power class information for each carrier, the base station can optimize power allocation locally for each carrier rather than applying a uniform allocation based on total power class, improving both channel allocation efficiency and power allocation adaptability.
