Delay Status Reporting Trigger Selection for Wireless Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack flexibility in delay status reporting (DSR) procedures, often relying on a single triggering event, which can lead to inefficient resource management and scheduling.
Innovation Solution
Implementing a dynamic DSR configuration that allows user equipment (UE) to select a triggering event from a set based on radio conditions and traffic patterns, enabling more flexible and responsive delay status reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single triggering event is used for delay status reporting, then the system complexity is reduced and ease of operation is improved, but the adaptability to different radio conditions and traffic patterns deteriorates
Solution Approach 1:
The patent implements dynamic triggering event selection where the UE can choose from multiple configured triggering events (e.g., different buffer threshold levels) based on current radio conditions and traffic patterns. This allows the DSR procedure to adapt its triggering behavior dynamically rather than using a fixed single threshold, resolving the contradiction between operational simplicity and adaptability.
Solution Approach 2:
The system changes the triggering parameter (buffer threshold) based on different operational conditions. The network configures multiple triggering events with different threshold values, and the UE selects appropriate thresholds based on radio condition quality and traffic pattern characteristics, enabling the same DSR mechanism to work effectively across diverse scenarios.
2Adaptability or versatility
If multiple triggering events are configured for delay status reporting, then the adaptability to different radio conditions and traffic patterns is improved, but the device complexity and information processing requirements increase
Solution Approach 1:
The patent segments the triggering event configuration into multiple discrete threshold levels (e.g., first threshold, second threshold, third threshold) that are independently configured by the network. This segmentation allows the UE to process and select from predefined options rather than handling complex continuous parameter optimization, reducing processing complexity while maintaining adaptability.
Solution Approach 2:
The UE autonomously selects the appropriate triggering event from the configured set based on its own assessment of radio conditions and traffic patterns. This self-service mechanism eliminates the need for complex network-controlled selection algorithms, distributing the intelligence to the edge device where the actual monitoring and selection occurs.
3Productivity
If dynamic triggering event selection is implemented, then the scheduling efficiency and resource allocation are improved, but the loss of time for triggering event evaluation increases
Solution Approach 1:
The network pre-configures multiple triggering events with different threshold values before the UE needs to make selection decisions. This preliminary configuration eliminates the need for real-time complex calculations, as the UE only needs to compare current buffer status against pre-defined thresholds and select the appropriate pre-configured event, significantly reducing evaluation time.
Solution Approach 2:
The system implements feedback mechanisms where the UE monitors radio conditions and traffic patterns continuously, and this feedback information directly influences the selection of triggering events. The feedback loop enables rapid adaptation without extensive evaluation because the selection logic is driven by straightforward condition checks rather than complex optimization algorithms.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may dynamically trigger a delay status reporting procedure based on multiple delay status reporting triggers. For example, the UE may receive, from a network entity of a serving cell of the UE, a delay status reporting configuration including an indication of multiple triggering events associated with delay status reporting for one or more logical channels of the UE. The UE may transmit, in accordance with the delay status reporting configuration, a report indicative of a delay status of a first logical channel of the one or more logical channels based on a first triggering event of the multiple triggering events being satisfied. The UE may select the first triggering event from the multiple triggering events based on a radio condition associated with the UE, a traffic pattern associated with the first logical channel, or both.
