Small Data Transmission Data Amount Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, accurately determining the total data amount for small data transmission (SDT) is challenging due to the diversity of uplink data and related data, leading to potential SDT failures or delays.
Innovation Solution
A method is provided to determine the total data amount by calculating the uplink data, packet header, and auxiliary information required for transmission, and configuring thresholds for candidate SDT types, allowing the terminal to select the appropriate SDT type based on the total data amount and thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal transmits uplink data in an unconnected state using SDT, then connection recovery is enabled, but accurate determination of total data amount becomes challenging due to diversity of uplink data and related data
Solution Approach 1:
The patent segments the total data amount calculation into three distinct components: uplink data amount (first data amount), packet header amount (second data amount), and auxiliary information amount (third data amount). This segmentation allows each component to be calculated and managed separately, improving measurement precision while maintaining reliable SDT transmission.
Solution Approach 2:
The patent performs preliminary calculation of the total data amount before initiating SDT transmission. By determining the first data amount of uplink data, second data amount of packet headers, and third data amount of auxiliary information in advance, the system ensures accurate data amount determination and prevents SDT failures or delays.
2Productivity
If the terminal selects appropriate SDT type based on total data amount and thresholds, then resource usage is optimized, but SDT failures or delays may occur due to inaccurate data amount determination
Solution Approach 1:
The patent performs preliminary calculation of the total data amount by summing the first data amount (uplink data), second data amount (packet header), and third data amount (auxiliary information) before SDT transmission. This advance calculation enables accurate comparison with thresholds, ensuring appropriate SDT type selection and preventing transmission delays.
Solution Approach 2:
The patent establishes a feedback mechanism where the calculated total data amount is compared against configured thresholds to determine the appropriate SDT type. This feedback loop ensures that the terminal selects the most suitable transmission mode based on actual data requirements, optimizing resource usage while preventing transmission failures.
