Small Data Transmission Resource Configuration for Uplink Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Small Data Transmission (SDT) technology, the limited availability of uplink transmission resources leads to delayed data delivery when handling large amounts of data, as terminals can only send data in an IDLE or INACTIVE state using a single resource, resulting in inadequate data transmission capacity.
Innovation Solution
A data transmission processing method and apparatus that obtain configuration information for small data transmission, which includes multiple uplink transmission resources (N > 1), allowing the terminal to determine whether to trigger small data transmission based on this information, thereby utilizing multiple resources for enhanced data transmission capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only one small data transmission resource is configured, then the terminal can directly send data in IDLE or INACTIVE state, but data transmission is delayed when large amounts of data need to be transmitted
Solution Approach 1:
The patent divides the single uplink transmission resource into multiple resources (first uplink transmission resource and second uplink transmission resource). The terminal can select from multiple resources based on data amount thresholds, allowing parallel transmission of large datasets while maintaining the simplicity of direct transmission operation in IDLE/INACTIVE states.
Solution Approach 2:
The patent introduces dynamic resource selection where the terminal determines which uplink transmission resource to use based on real-time data amount assessment. When data amount exceeds a threshold, the terminal switches to using multiple resources dynamically, optimizing transmission capacity without complicating the basic operation flow.
2Productivity
If multiple uplink transmission resources are configured, then data transmission capacity is enhanced, but the complexity of determining whether to trigger small data transmission increases
Solution Approach 1:
The patent uses data amount as a key parameter to dynamically determine resource usage. By comparing the data amount against predefined thresholds, the terminal automatically selects appropriate transmission resources without complex decision logic. This parameter-based approach simplifies the determination process while enabling multiple resource utilization when needed.
3Productivity
If multiple uplink transmission resources are used, then larger data amounts can be transmitted, but resource overoccupation may occur
Solution Approach 1:
The patent implements feedback mechanisms where the network side device monitors resource usage and provides guidance on resource selection. The terminal adjusts its resource selection based on network conditions and feedback information, preventing resource over-occupation while maximizing data transmission capacity through multiple resources.
