Terminal Configured Grant Selection for Uplink Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future radio communication systems, particularly in New Radio (NR), the lack of specification on when to perform configured grant-based transmission leads to decreased communication throughput when multiple configured grants are configured for uplink transmission.
Innovation Solution
A terminal is designed with a reception section to receive information on configured grant configurations and a control section that determines the appropriate configured grant configuration based on the number of repeats and redundancy version for each configuration, ensuring optimal transmission occasions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple configured grants are configured for uplink transmission, then transmission capacity is improved, but communication throughput decreases due to unspecified transmission timing
Solution Approach 1:
The patent applies parameter changes by determining the transmission timing based on changing parameters (number of repeats and redundancy version) of the configured grants. The control section selects which configured grant to use by evaluating these parameters, thereby optimizing throughput while maintaining the ability to perform multiple transmissions.
2Adaptability or versatility
If multiple configured grants are configured, then uplink transmission flexibility is improved, but device complexity increases due to lack of determination rules
Solution Approach 1:
The terminal performs self-service by autonomously determining which configured grant to use based on pre-configured parameters (number of repeats and redundancy version). The control section automatically selects the appropriate grant without external intervention, simplifying the control process while maintaining transmission flexibility.
3Ease of operation
If configured grant-based transmission is performed without appropriate timing specification, then transmission simplicity is maintained, but communication efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring the parameters (number of repeats and redundancy version) for each configured grant before transmission occurs. The control section uses these pre-established parameters to automatically determine the optimal transmission timing, thereby maintaining simplicity while improving efficiency without requiring complex real-time decisions.

AI summary
An aspect of a terminal according to the present disclosure includes: a reception section that receives information regarding a configured grant configuration; and a control section that, when a multi configured grant configuration is configured, determines a configured grant configuration to be applied based on the number of repeats and a redundancy version corresponding to each configured grant configuration.
