Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future radio communication systems, when multiple configured grants are configured for a user equipment (UE), it is unclear how to determine which grant to use, leading to potential system performance deterioration.
Innovation Solution
A user terminal that determines the appropriate configured grant configuration based on traffic type and occurrence timing, allowing flexible and efficient use of multiple configured grants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple configured grants are configured for a user equipment, then the capacity and sophistication of the system are increased, but it becomes unclear how to determine which grant to use, leading to system performance deterioration
Solution Approach 1:
The patent changes the parameter of grant selection by introducing dynamic selection criteria based on traffic type (e.g., eMBB, URLLC, mMTC) and traffic occurrence timing (whether traffic occurs before or after a reference time point). This allows the system to adaptively choose among multiple configured grants according to specific transmission conditions, resolving the ambiguity in grant selection while maintaining system performance.
2Productivity
If multiple configured grants are configured, then more transmission resources are available, but the complexity of determining which grant to use increases
Solution Approach 1:
The patent applies local quality by assigning different configured grants to different traffic types and timing conditions. Each configured grant is optimized for specific local conditions (e.g., one grant for eMBB traffic, another for URLLC traffic), allowing the system to maintain high transmission capacity while simplifying the selection process through condition-based matching rather than complex optimization.
3Reliability
If an appropriate configured grant is not selected, then system performance deteriorates, but selecting the wrong grant wastes transmission resources
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple grants with specific characteristics and pre-establishing selection criteria based on traffic type and timing. When transmission is needed, the system quickly matches current conditions to the pre-defined criteria, ensuring appropriate grant selection without complex real-time optimization, thus preventing both performance deterioration and resource waste.

AI summary
A user terminal includes a control section that determines at least one of a plurality of configured grant configurations based on at least one of a type of traffic and traffic occurrence timing, and a transmission section that performs transmission by using the determined configured grant configuration. According to the aspect of the present disclosure, the operation can be appropriately performed even when the plurality of configured grants are configured.
