Spacing Symbol Data Transmission Accuracy in 5G High Subcarrier Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G systems, determining whether to transmit data on spacing symbols with high accuracy is challenging due to transient times caused by power or frequency changes between consecutive short subslot transmission symbols, especially when subcarrier spacing is high.
Innovation Solution
A communication method and device that acquire and determine the position or proportion of transient times in spacing symbols, using acquired data to decide whether to transmit data, with the aid of preset rules and capability information from terminal devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high subcarrier spacing is used in 5G system, then transmission efficiency is improved, but determination accuracy of data transmission on spacing symbols deteriorates due to transient times
Solution Approach 1:
The patent applies preliminary action by acquiring capability information from terminal devices in advance that indicates their support for transient times. This capability information is stored and used later to accurately determine whether to transmit data on spacing symbols, resolving the contradiction between high subcarrier spacing efficiency and determination accuracy.
2Reliability
If transient times are considered in spacing symbols, then data transmission reliability is improved, but device complexity increases due to additional capability information management
Solution Approach 1:
The patent applies self-service by having terminal devices autonomously provide their own capability information regarding transient time support. The network device uses this self-provided information to make transmission decisions, improving reliability while minimizing additional complexity since the terminal devices are already managing their own capabilities.
Solution Approach 2:
The capability information indicating terminal support for transient times is acquired and stored in advance. This preliminary acquisition allows the system to make informed transmission decisions on spacing symbols without adding complex real-time processing, thus improving reliability while controlling device complexity.
