Dynamic Scheduling Request Thresholds for Multi-Channel UE Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack flexibility in scheduling request procedures, leading to inefficient radio resource management due to the use of single thresholds for scheduling requests, which do not account for varying data types and activities at the user equipment (UE).
Innovation Solution
Implementing a dynamic scheduling request procedure where the UE selects a threshold from a range of thresholds and parameters, such as scheduling request counts or prohibit timer durations, based on traffic patterns, machine learning algorithms, or both, to transmit scheduling requests for logical channels and monitor for scheduling grants, enhancing radio resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single threshold is used for scheduling requests, then the system operation is simple, but the adaptability to different data types and activities is poor
Solution Approach 1:
The patent segments the scheduling request configuration by dividing it into multiple ranges (first range, second range, etc.) for different parameters. Each range corresponds to different data types or activity patterns, allowing the UE to select appropriate thresholds based on specific conditions rather than using a single uniform threshold for all scenarios.
Solution Approach 2:
The patent implements dynamic threshold selection by enabling the UE to dynamically choose from multiple configured ranges based on real-time conditions such as data type and activity. This transforms the static single-threshold system into a dynamic multi-range system that adapts to varying operational requirements.
2Adaptability or versatility
If multiple ranges and parameters are configured for scheduling requests, then the adaptability to different data types and activities is improved, but the device complexity increases
Solution Approach 1:
The patent changes the parameters of the scheduling request configuration by introducing multiple ranges for different parameters (such as different threshold values, different counts, different timer durations) instead of using fixed single values. This allows the system to adapt to different data types and activities by selecting appropriate parameter combinations from the configured ranges.
3Productivity
If dynamic threshold selection is implemented, then the radio resource management efficiency is improved, but the processing complexity at UE increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple ranges and thresholds at the network side before the UE needs to make scheduling decisions. The UE receives and stores these pre-configured ranges, so when dynamic selection is needed, the UE only needs to evaluate which pre-configured range applies rather than computing optimal thresholds from scratch, reducing real-time processing complexity.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may dynamically perform a scheduling request procedure based on multiple ranges associated with respective parameters of a set of parameters. For example, the UE may receive, from a network entity of a serving cell of the UE, signaling indicating a scheduling request configuration including an indication of multiple ranges associated with respective parameters of a set of parameters, the scheduling request configuration associated logical channels of a set of multiple logical channels of the UE. The UE may transmit, in accordance with the scheduling request configuration, a scheduling request for a first logical channel based on a first parameter satisfying a selected threshold, where the selected threshold is within a first range associated with the first parameter. The UE may monitor for a scheduling grant associated with the first logical channel based on the scheduling request.
