Small Data Transmission Thresholds for Inactive 5G User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G-NR systems, frequent small data transmissions from user equipment in an inactive state lead to unnecessary power consumption and signaling overhead due to frequent state changes, despite the inefficiency of initiating such transmissions for small payloads.
Innovation Solution
Implementing data volume thresholds, including minimum and maximum limits, to control when small data transmissions are allowed, thereby reducing unnecessary state changes and resource consumption by ensuring data volume meets specific criteria before initiating transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If small data transmission is allowed in inactive state, then power consumption is reduced, but signaling overhead increases due to frequent transmissions
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the data volume threshold based on network conditions, UE behavior patterns, and service types. The network can modify the threshold parameter to balance between allowing SDT (reducing power consumption) and preventing excessive signaling overhead, thereby resolving the contradiction adaptively
2Productivity
If data volume threshold is set low, then transmission opportunities increase, but resource waste increases due to small payloads
Solution Approach 1:
The patent implements partial action by setting a minimum data volume threshold that prevents overly small transmissions. Instead of allowing every possible small transmission (excessive action), the threshold filters out transmissions that would cause more overhead than benefit, while still permitting sufficiently small transmissions that provide real value, thus achieving optimal balance
3Loss of energy
If data volume threshold is set high, then resource efficiency improves, but transmission opportunities are reduced
Solution Approach 1:
The patent applies dynamics by making the data volume threshold adjustable rather than fixed. The threshold can be dynamically modified based on current network load, UE activity patterns, and service requirements, allowing the system to optimize between resource efficiency and transmission opportunities in real-time different conditions
