Uplink Grant Selection for Wireless Transmission Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current wireless networks, the overlap between configured and dynamic uplink grants leads to inefficient data transmission, as terminal devices often drop available data in configured grants due to selecting dynamic grants regardless of data availability, resulting in poor transmission efficiency.
Innovation Solution
A method where a terminal device determines the overlap between configured and dynamic uplink grants and selects a target uplink grant for data transmission, allowing flexible choice between the two grants to optimize data transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device always selects the dynamic uplink grant for data transmission, then the adaptability of resource allocation is improved, but the transmission efficiency deteriorates when the dynamic grant has no data while configured grant has data
Solution Approach 1:
The terminal device dynamically selects between configured uplink grant and dynamic uplink grant based on real-time data availability conditions. When data is available in the configured grant, the terminal switches to use the configured grant for transmission; when no data is available, it uses the dynamic grant. This dynamic selection mechanism resolves the contradiction by making the system adaptable to different data conditions while maintaining high transmission efficiency.
Solution Approach 2:
The invention changes the selection parameter from a fixed rule (always prefer dynamic grant) to a conditional parameter based on data availability. The terminal device checks whether data is available in the configured grant and adjusts its selection accordingly, transforming the rigid parameter into a flexible one that adapts to actual transmission needs, thereby resolving the efficiency loss when dynamic grants are used unnecessarily.
2Device complexity
If the terminal device uses configured uplink grants, then the resource allocation simplicity is improved, but the transmission efficiency deteriorates due to overlap with dynamic grants
Solution Approach 1:
The terminal device employs a dynamic selection mechanism that evaluates both configured and dynamic uplink grants based on data availability. Instead of statically preferring one grant type, the system dynamically switches between them according to real-time conditions, maintaining the simplicity of configured grants while eliminating efficiency losses from unnecessary dynamic grant usage.
3Ease of operation
If the terminal device selects uplink grants based on fixed rules, then the operation simplicity is improved, but the resource utilization efficiency deteriorates
Solution Approach 1:
The invention replaces fixed selection rules with a dynamic conditional selection process. The terminal device checks data availability in the configured grant and adjusts its grant selection accordingly. This maintains operational simplicity through a clear decision logic while dramatically improving resource utilization by ensuring data is transmitted whenever possible, regardless of whether it comes from configured or dynamic grants.
