Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in improving data reception reliability, particularly in scenarios where the same data is repeatedly transmitted, as existing methods do not effectively combine signals to enhance reception performance.
Innovation Solution
The proposed solution involves a method and apparatus that utilize multiple transmission and reception points to repeatedly transmit the same data, allowing for signal combination at the receiver to enhance reception reliability in wireless communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same data is repeatedly transmitted in a wireless communication system, then the reliability of data reception is improved, but the complexity of signal combination at the receiver increases
Solution Approach 1:
The patent segments the repeated transmissions into distinct transmission instances from multiple TRPs, allowing the receiver to process each transmission separately and combine them systematically. This segmentation approach manages complexity by breaking down the signal combination task into manageable units corresponding to each transmission instance.
Solution Approach 2:
The patent merges signals from multiple transmission points carrying the same data at the receiver side. By combining these signals through appropriate signal processing techniques, the system achieves diversity gain and improves reception reliability while managing the combination complexity through structured approaches.
2Reliability
If multiple transmission points are used to repeatedly transmit the same data, then the reception performance is enhanced, but the system complexity increases
Solution Approach 1:
The patent implements a universal transmission framework where multiple TRPs can simultaneously serve multiple users with repeated transmissions. This multi-functional approach allows the same mechanism to handle various transmission scenarios, enhancing reception performance while managing system complexity through standardized procedures.
Solution Approach 2:
Instead of having a single complex transmitter, the patent inverts the approach by using multiple simpler transmission points. Each TRP performs simpler individual transmissions, and the complexity is shifted to the receiver side where signals are combined, thereby distributing and managing system complexity more effectively.
3Reliability
If signal combination techniques are applied at the receiver, then the data reception reliability is improved, but the processing complexity at the terminal increases
Solution Approach 1:
The patent applies preliminary actions by pre-configuring the receiver with knowledge of expected repeated transmissions from multiple TRPs. This allows the terminal to prepare appropriate combination strategies in advance, reducing real-time processing complexity while maintaining improved reception reliability through systematic signal combining.
