Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RedCap terminals, designed for low-cost and low-complexity applications, face limitations in performing small data transmissions (SDT) due to differing RSRP values with varying antenna structures, limiting their communication opportunities compared to non-RedCap terminals.
Innovation Solution
Adopting configuration information to set threshold values or bias values based on the first type antenna structure for RedCap terminals to determine signal quality, enabling them to perform SDT more effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RedCap terminals use the same SDT threshold values as non-RedCap terminals, then the system maintains simple threshold configuration, but RedCap terminals with different antenna structures cannot meet SDT conditions due to differing RSRP values
Solution Approach 1:
The patent applies local quality by configuring different threshold values or bias values specifically for RedCap terminals with different antenna structures (e.g., single-antenna vs. multi-antenna terminals). This allows each terminal type to have optimized thresholds adapted to its specific antenna characteristics, thereby improving SDT opportunities for RedCap terminals without requiring complete redesign of the threshold system
Solution Approach 2:
The patent introduces bias values as adjustable parameters that can be configured for different RedCap terminal types. By changing the threshold parameters (either direct threshold values or bias offsets from reference values) based on antenna structure, the system adapts to different terminal capabilities while maintaining a structured configuration approach
2Ease of operation
If RedCap terminals use fixed threshold values for SDT, then the threshold configuration remains simple, but terminals with varying antenna structures experience limited communication opportunities
Solution Approach 1:
The patent enables terminals to determine thresholds by applying bias values to reference threshold values. This parameter change approach allows terminals with different antenna structures to adjust their effective thresholds through the bias value, improving ease of SDT performance while keeping the determination process systematic rather than completely fixed
3Productivity
If the system uses antenna-specific threshold values for RedCap terminals, then SDT opportunities increase, but the configuration and management of thresholds becomes more complex
Solution Approach 1:
The patent implements local quality by providing specific threshold configurations or bias values for different RedCap terminal types based on their antenna structures. This targeted approach increases transmission opportunities for each terminal type while concentrating the complexity only where needed (in the configuration data) rather than in the overall system operation
Solution Approach 2:
The patent uses bias values as intermediary parameters that mediate between reference threshold values and the actual thresholds applied by different terminal types. This intermediary mechanism allows the system to manage antenna-specific configurations through a standardized bias value approach, reducing the overall configuration complexity while still achieving terminal-specific optimization

AI summary
A wireless transmission method is performed by a terminal. The method includes: determining a threshold value of signal quality for the terminal to perform small data transmission (SDT) based on configuration information, wherein the configuration information is configured to indicate at least one of: a predetermined threshold value of signal quality for a terminal with a first type antenna structure to perform the SDT; or a bias value of a reference threshold value of the signal quality for the terminal with the first type antenna structure to perform the SDT.
