Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G communication systems face challenges in efficiently determining random access resources and data resources for user equipment (UE) in IoT networks, leading to potential conflicts and delays in message processing due to overlapping uplink signals.
Innovation Solution
A method for UE to obtain and validate random access and data resources based on configuration information, perform validation detection, and manage overlapping uplink signals by prioritizing transmission according to predetermined conditions, allowing for distinct random access response windows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If random access resources and data resources are determined based on configuration information without validation detection, then resource allocation is simple, but resource conflicts and overlaps occur leading to message processing delays
Solution Approach 1:
The patent performs validation detection on random access resources and data resources before actual transmission. This preliminary validation identifies and resolves resource conflicts and overlaps in advance, ensuring reliable resource allocation without causing message processing delays during actual communication.
Solution Approach 2:
The patent implements a feedback mechanism where the validation detection results are used to adjust and optimize resource allocation. By monitoring resource conflicts and providing feedback to the resource determination process, the system continuously improves allocation accuracy while managing complexity through learned patterns.
2Productivity
If overlapping uplink signals are transmitted simultaneously, then transmission efficiency is high, but signal interference increases causing transmission errors
Solution Approach 1:
The patent performs preliminary validation detection to identify overlapping uplink signals before transmission. By detecting potential interference in advance, the system can prioritize signals appropriately, ensuring reliable transmission while maintaining high efficiency through optimized signal scheduling.
Solution Approach 2:
The patent introduces a validation detection mechanism as an intermediary between resource allocation and signal transmission. This intermediary layer analyzes resource configurations, identifies overlaps, and applies prioritization rules to resolve conflicts, thereby maintaining both transmission efficiency and reliability.
3Adaptability or versatility
If a single random access response window is used for all message transmissions, then window management is simple, but feedback timing cannot be optimized for different message types
Solution Approach 1:
The patent segments the random access response window management by creating distinct windows for different message types (message A and message B). This segmentation allows each window to be optimized for its specific message type's timing requirements, improving adaptability while keeping individual window management relatively simple through clear separation of concerns.
