Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wireless communication systems face challenges in efficiently managing and prioritizing communication resources, particularly for uplink transmission, due to overlapping or ambiguously assigned resources.
Innovation Solution
A method and system for operating a wireless device in a wireless communication network, where a control information message determines the selection between overlapping first and second transmission resources, allowing for improved resource prioritization and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transmission resources are assigned to a wireless device, then resource utilization and transmission flexibility are improved, but resource management complexity and signal quality deteriorate due to overlapping resources
Solution Approach 1:
A control information message acts as an intermediary to resolve resource conflicts. The message contains explicit prioritization indicators that guide the wireless device in selecting which overlapping transmission resource to use, thereby simplifying the device's decision-making process while maintaining flexible resource assignment capability
Solution Approach 2:
The system dynamically changes the prioritization parameter in control information messages based on network conditions and service requirements. By adjusting which resource is indicated as having higher priority, the system can adapt resource allocation to different scenarios without increasing device complexity
2Productivity
If multiple transmission resources are assigned to a wireless device, then resource utilization is improved, but transmission reliability deteriorates due to overlapping resources causing artifacts
Solution Approach 1:
The control information message serves as a mediator that prevents harmful interference by explicitly indicating which resource should be prioritized. This resolves the conflict between overlapping resources, ensuring that only one resource is actively used for transmission at any given time, thereby maintaining signal quality and transmission reliability
Solution Approach 2:
The system takes preliminary action by providing prioritization indicators before the wireless device makes its transmission decision. This preemptive guidance prevents the device from selecting conflicting resources, thereby avoiding the creation of transmission artifacts and maintaining signal integrity
3Speed
If the wireless device autonomously selects from overlapping resources, then response speed is improved, but resource allocation precision deteriorates
Solution Approach 1:
The network performs preliminary action by pre-calculating and indicating the optimal resource selection through control information messages. This allows the wireless device to quickly follow the pre-determined optimal choice without needing to perform complex autonomous analysis, thereby maintaining both fast response and precise resource allocation
Solution Approach 2:
The control information message provides feedback from the network to the wireless device regarding which resource should be selected. This feedback mechanism ensures that the device's autonomous selection aligns with network-wide optimization goals, maintaining allocation precision while enabling rapid device-side decision-making
