Configured Grant Grouping for Overlapping Uplink Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems 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 hampers uplink throughput and reliability.
Innovation Solution
A method for determining multiple configured grant configurations based on radio resource control signaling and downlink control information, allowing simultaneous transmission of fully or partially overlapping channels by selecting and grouping configurations using parameters like CORESET pool index and SRS resource set index.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system determines only one configured grant configuration at a time, then the system complexity is low and operation is simple, but the uplink throughput and resource utilization are limited
Solution Approach 1:
The patent segments the configured grant configurations into multiple groups (first group and second group) based on different parameter values such as CORESET pool index or SRS resource set index. This segmentation allows the system to determine multiple configurations simultaneously by evaluating each group separately, thereby improving uplink throughput without overwhelming the system with complex unified processing.
Solution Approach 2:
The patent introduces a new dimension of classification by grouping configurations according to parameter values (CORESET pool index, SRS resource set index). This dimensional approach transforms the problem from determining a single configuration to determining multiple configurations across different dimensional groups, enabling simultaneous multi-panel uplink transmissions while maintaining manageable system complexity through structured organization.
2Productivity
If the system supports only single-panel uplink transmission, then the device complexity is low, but the resource utilization is insufficient
Solution Approach 1:
The patent implements multi-functionality by enabling the terminal device to perform both single-panel and multi-panel uplink transmissions using the same configured grant configuration determination mechanism. By determining multiple configured grant configurations simultaneously based on different parameter groups, the system achieves universal support for both transmission modes, improving resource utilization without requiring entirely separate systems for each mode.
3Reliability
If the system determines multiple configured grant configurations simultaneously, then the uplink throughput and resource utilization improve, but the complexity of determining and managing configurations increases
Solution Approach 1:
The patent reduces configuration management complexity by segmenting the determination process into distinct groups based on parameter values. Each group (first group, second group) is evaluated separately using the same determination logic, which maintains operational simplicity while enabling simultaneous multi-panel transmissions. This segmented approach improves transmission reliability through diversified configuration options without proportionally increasing management complexity.
