Configured Grant Uplink Scheduling for Overlapping PUSCH Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies can only determine one configured grant configuration at a time, limiting the ability to handle multiple configured grant configurations that overlap in the time domain, which affects uplink throughput and reliability.
Innovation Solution
A method is provided to determine multiple configured grant configurations based on radio resource control signaling and downlink control information, allowing for the selection and grouping of configurations with overlapping time domain resources, and multiplexing uplink control information into configured grant physical uplink shared channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only one configured grant configuration is determined at a time, then the system is simple to operate, but the uplink throughput and resource utilization are limited
Solution Approach 1:
The patent segments the configured grant configuration determination process by introducing a configured grant configuration index parameter that identifies different configured grant configurations. This allows the system to determine and manage multiple configured grant configurations (first configured grant configuration, second configured grant configuration, etc.) simultaneously, each with its own time domain resources, rather than being limited to a single configuration at a time.
Solution Approach 2:
The patent adds a new dimension to the configuration management system by introducing the configured grant configuration index parameter as an additional identifier dimension. This enables the system to distinguish between multiple configured grant configurations that may have overlapping time domain resources, allowing simultaneous determination of multiple configurations without confusion or resource conflicts.
2Productivity
If multiple configured grant configurations with overlapping time domain resources are determined, then resource utilization improves, but the difficulty of detecting and measuring configurations increases
Solution Approach 1:
The patent applies local quality by assigning unique configured grant configuration index parameters to different configured grant configurations. This allows the system to locally identify and distinguish between specific configurations (e.g., first configured grant configuration with index 1, second configured grant configuration with index 2) even when their time domain resources overlap, making detection and measurement straightforward through the index parameter.
Solution Approach 2:
The configured grant configuration index parameter serves as an intermediary that mediates between multiple configured grant configurations with overlapping time domain resources. This intermediary parameter enables the system to uniquely identify and manage each configuration without direct complexity in detecting and measuring the overlapping resources themselves.
3Reliability
If multiple configured grant configurations are determined simultaneously, then uplink transmission reliability improves, but the device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple configured grant configurations with their respective index parameters, time domain resources, and other parameters before actual uplink transmission. This allows the terminal device to have multiple ready-to-use configurations (first configured grant configuration, second configured grant configuration, etc.) that can be quickly selected and executed, improving transmission reliability without adding complexity during the actual transmission process.
Solution Approach 2:
The patent uses parameter changes by introducing the configured grant configuration index parameter as a key discriminator. By changing and managing this index parameter along with other configuration parameters (time domain resources, frequency domain resources, etc.), the system can efficiently manage multiple configured grant configurations simultaneously, improving reliability while keeping device complexity manageable through systematic parameter management.
