UE Remaining-Time Reporting for Delay-Budgeted Data Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The communication standard does not specify how a user equipment (UE) should report the remaining time of to-be-transmitted data to a base station, which is crucial for ensuring timely data scheduling and transmission within the delay budget required by extended reality (XR) services.
Innovation Solution
A communication method where the UE determines the remaining time of data packets based on the duration of a timer and sends specific information to the base station, indicating the remaining time or time intervals, thereby enabling effective resource scheduling and reducing transmission resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE reports remaining time of to-be-transmitted data to the base station, then the base station can perform resource scheduling within the delay budget, but the communication standard does not specify how the UE should report the remaining time
Solution Approach 1:
The patent applies parameter changes by transforming the remaining time information into different reporting formats (remaining time value, time interval, or threshold indication) based on the timer type and data packet characteristics. This allows the system to adapt the reporting mechanism to different scenarios while maintaining reliability within the delay budget.
Solution Approach 2:
The patent segments the reporting mechanism into different types based on timer classification (first type timer for individual data packets, second type timer for data packet sets). Each timer type has specific reporting requirements, which simplifies the overall complexity by dividing the problem into manageable segments with distinct handling rules.
2Measurement precision
If the UE determines remaining time based on timer duration and sends detailed information to the base station, then resource scheduling accuracy is improved, but transmission resource overhead increases
Solution Approach 1:
The patent implements partial action by providing different levels of reporting detail based on the situation. The UE can report only the necessary information (remaining time value, time interval, or threshold indication) rather than complete detailed information in all cases. This reduces transmission resource overhead while maintaining sufficient precision for resource scheduling decisions.
3Productivity
If the network completes data scheduling and transmission within the delay budget, then service experience is improved, but data timeout occurs when transmission exceeds the delay budget
Solution Approach 1:
The patent applies preliminary action by having the UE determine and report the remaining time of to-be-transmitted data before actual transmission occurs. The base station uses this advance information to perform resource scheduling that ensures data packets are transmitted within their delay budgets, preventing timeout before it happens.
Solution Approach 2:
The patent implements feedback by continuously monitoring the remaining time of data packets and providing updates to the base station. This feedback mechanism allows the base station to adjust resource scheduling dynamically to ensure data is transmitted within the delay budget while maximizing transmission efficiency.

AI summary
A communication method, a communication apparatus, a computer-readable storage medium, and a computer program product. A maximum remaining transmission delay of data is determined for the data based on remaining duration of a timer maintained for the data, that is, remaining time of the data is determined. The remaining time is reported to an access network device so that the access network device can schedule the data based on the remaining time to help successful transmission of the data within a budgeted transmission delay, and to improve a transmission success rate of the data.
