Transmit Energy Report for Uplink Power Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face performance degradation and increased overhead due to lack of accurate power budget information at base stations, leading to suboptimal scheduling and resource allocation for user equipment (UE) transmissions, which affects uplink transmission characteristics.
Innovation Solution
Implementing a method for user equipment (UE) to calculate and report predicted transmission power to the base station, allowing for dynamic adjustment of uplink transmission characteristics based on threshold values and maximum permissible exposure events, thereby enhancing scheduling accuracy and reducing control overhead.

Engineering Contradiction Analysis
1Measurement precision
If the base station schedules transmissions without accurate power budget information, then scheduling decisions can be made, but scheduling accuracy deteriorates and performance degrades
Solution Approach 1:
The UE performs preliminary calculations of the transmit energy report (TER) and power budget information before the base station needs to make scheduling decisions. By pre-computing these power-related metrics and reporting them to the base station, the scheduling accuracy is improved without requiring complex real-time measurements at the base station.
Solution Approach 2:
The UE continuously monitors its own power budget and transmission characteristics, then feeds back this information to the base station in the form of TER reports. This feedback mechanism enables the base station to make informed scheduling decisions based on accurate, up-to-date power budget information from the UE.
2Measurement precision
If the UE reports detailed power information frequently, then scheduling accuracy improves, but control overhead increases
Solution Approach 1:
The patent extracts only the most critical power-related information (transmit energy report) from the full power budget data and reports only this essential subset to the base station. This selective reporting maintains scheduling accuracy while minimizing the amount of control signaling required.
Solution Approach 2:
The UE dynamically adjusts the granularity and frequency of TER reporting based on changes in transmission characteristics. When power budget conditions remain stable, reporting frequency is reduced; when significant changes occur, reporting is triggered. This adaptive approach optimizes the balance between information accuracy and control overhead.
