Terminal Power Reporting for Carrier Aggregation Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems with dual power amplifiers supporting carrier aggregation/dual connectivity, the network device is unaware of transmission power fluctuations in terminals due to regulatory constraints, leading to inefficient scheduling and potential power consumption issues.
Innovation Solution
The terminal reports power domain information to the network device under specific conditions, enabling more optimal scheduling and reducing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the terminal operates with dual power amplifiers supporting carrier aggregation/dual connectivity, then the transmission power capability is enhanced, but the network device becomes unaware of transmission power fluctuations due to regulatory constraints
Solution Approach 1:
The terminal feeds back power domain information to the network device through uplink signaling when specific triggering conditions are met. This feedback mechanism enables the network device to become aware of the terminal's transmission power status and regulatory constraint impacts, resolving the information asymmetry while maintaining dual PA operation capabilities.
2Productivity
If the terminal reports power domain information frequently, then the network device achieves more optimal scheduling, but the terminal consumes more power
Solution Approach 1:
Instead of continuous reporting, the terminal employs periodic reporting triggered by specific conditions such as power domain changes, pathloss changes exceeding thresholds, or entry/exit from special subframes. This conditional periodic reporting achieves necessary scheduling optimization while minimizing unnecessary power consumption from frequent reports.
Solution Approach 2:
The terminal reports power domain information partially - only when changes occur or when triggered by specific conditions rather than continuously. This partial action provides the network device with sufficient information for scheduling decisions without requiring excessive reporting that would waste terminal power.
3Use of energy by moving object
If the terminal does not report power domain information, then the terminal power consumption is reduced, but the network device scheduling efficiency deteriorates
Solution Approach 1:
The terminal implements selective feedback of power domain information to the network device. By providing this feedback under specific conditions, the network device gains the necessary information to improve scheduling efficiency without requiring continuous reporting that would increase terminal power consumption.

AI summary
The present disclosure relates to a power information reporting method and apparatus, a device and a storage medium. The method comprises: in response to a terminal sanctifying a reporting control condition, determining power domain information of the terminal, the power domain information being used for indicating information related to terminal power; and sending the power domain information to a network device. By means of the reporting control condition, the terminal can send the power domain information to the network device, thus supporting efficient and reasonable terminal enhancement reporting, which is conducive to a network to achieve more optimal scheduling, and more suitable for service sending demand scheduling. Furthermore, the system throughput and the user coverage are improved, which is conducive to improving the system efficiency, reducing the invalid scheduling of the network device, and saving unnecessary power consumption tor the terminal.
