5G UE Transmission Direction Determination for Ambiguous Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, unclear transmission direction information can lead to chaotic UE behavior and system instability due to flexible resource configuration, resulting in poor user experience and instability.
Innovation Solution
A method and apparatus for determining transmission direction information, where the UE uses preset rules to determine transmission direction for unclear information, avoiding system instability and improving reliability and user experience by dynamically acquiring and processing direction configuration information from the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible resource configuration is implemented with dynamic transmission direction information, then the system can meet diverse service requirements (eMBB, URLLC, mMTC), but unclear or conflicting direction configurations cause chaotic UE behavior and system instability
Solution Approach 1:
The patent applies preliminary action by establishing a preset rule before the conflict occurs. The rule specifies that when transmission direction information is unclear or conflicting, the UE should determine the direction based on whether the resource is in a downlink slot (downlink or flexible) or uplink slot (uplink or flexible). This pre-defined decision mechanism prevents chaotic behavior and ensures system stability while maintaining flexible resource configuration.
2Adaptability or versatility
If multiple direction configuration information are provided for the same transmission unit, then flexible service support is improved, but determination accuracy of transmission direction deteriorates
Solution Approach 1:
The patent applies local quality by making the direction determination rule context-dependent. The preset rule checks the local characteristic of the resource (whether it falls in downlink slot or uplink slot) and determines the transmission direction based on this local property. This allows the system to support multiple service types with different direction requirements while maintaining accurate direction determination through localized decision-making.

AI summary
The present disclosure provides a method and a device for determining transmission direction information. The method comprises: acquiring direction configuration information dynamically transmitted by a base station, the direction configuration information being used to indicate transmission direction information of an information transmission resource; determining, according to the direction configuration information, a target information transmission unit whose transmission direction indication is ambiguous; and determining, according to a preset rule, transmission direction information of the target information transmission unit. By employing the method for determining transmission direction information provided by the present disclosure, transmission direction information of transmission resources can be effectively clarified, thereby avoiding chaotic user equipment behavior, ensuring system stability and improving the user experience of user equipment in 5G networks.
