Wireless Delay Status Reporting with LCG Time Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient methods for reporting multiple delay status information, particularly in high-speed and high-capacity systems like 5G and beyond, which are essential for managing diverse services with varying latency and reliability requirements.
Innovation Solution
A method and device for reporting multiple delay statuses through a terminal and base station interaction, involving the transmission of first and second information related to delay status reports (DSR) and configuration of remaining time thresholds per logical channel group (LCG), enabling precise management of packet data convergence protocol service data units (SDUs).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single delay status report method is used, then the system is simple to operate, but it cannot provide detailed delay status information for multiple services with different latency requirements
Solution Approach 1:
The patent segments the delay status reporting by introducing multiple remaining time thresholds (first threshold, second threshold, etc.) that divide the delay status into multiple levels. Each threshold level provides granular delay information for different service requirements, allowing the system to report detailed delay status without requiring a completely complex new reporting framework
Solution Approach 2:
The patent changes the parameter of delay status reporting by introducing multiple remaining time thresholds instead of using a single threshold. This allows the system to provide differentiated delay information (first delay status, second delay status, etc.) for different service types, enabling both simplicity and detail through parameter variation
2Adaptability or versatility
If multiple delay status reports are implemented, then services with different latency requirements are supported, but the reporting mechanism becomes more complex
Solution Approach 1:
The patent creates a universal delay status reporting mechanism that can serve multiple services with different latency requirements through a single unified framework. By using multiple remaining time thresholds, the same reporting structure adapts to support eMBB, URLLC, and other services, achieving versatility without requiring separate reporting mechanisms for each service type
Solution Approach 2:
The patent introduces dynamic adaptability by allowing the system to selectively report different delay status levels based on service requirements. The base station can configure which remaining time thresholds to use, enabling the reporting mechanism to dynamically adapt to different service scenarios while maintaining a consistent underlying structure
3Productivity
If detailed delay status information is reported, then resource allocation is optimized, but the amount of information to be transmitted increases
Solution Approach 1:
The patent extracts only the essential delay status information needed for resource allocation by using remaining time thresholds. Instead of transmitting complete buffer status details, the system extracts and reports only the delay status relative to configured thresholds, reducing information volume while maintaining the precision needed for optimized resource allocation
Solution Approach 2:
The patent implements partial reporting by selectively reporting delay status information based on configured thresholds. The system reports only the portions of delay status that exceed or meet the threshold criteria, avoiding transmission of redundant information while providing sufficient detail for effective resource allocation decisions
Data Source
AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a wireless communication system is provided. The method includes transmitting, to a base station, first information indicating that the terminal supports a delay status report (DSR) of a buffered data, receiving, from the base station, configuration information on a plurality of remaining time thresholds per logical channel group (LCG), and transmitting, to the base station, second information including a remaining time field indicating the shortest remaining time among packet data convergence protocol (PDCP) service data units (SDUs) associated with a corresponding remaining time threshold of an LCG.
