UE Autonomous NR Deprioritization via Local Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing radio access technologies (RATs), particularly in deprioritizing NR (New Radio) RAT when it consumes more resources or is unstable, leading to potential performance degradation and inability to support voice calls.
Innovation Solution
A method and apparatus for a user equipment (UE) to autonomously deprioritize the NR RAT by receiving an indication and performing actions such as local connection release, redirecting to LTE frequencies, modifying cell reselection criteria, and suspending NR measurement reports, based on communication modes and RAT connections, without requiring external commands or updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the UE autonomously deprioritizes NR RAT by performing local connection release and redirecting to LTE, then signaling overhead is reduced and resource consumption is minimized, but the complexity of autonomous decision-making and communication mode detection increases
Solution Approach 1:
The UE autonomously monitors its own communication mode, detects NR RAT instability, and performs self-directed deprioritization actions including local connection release and redirection to LTE without requiring network commands. This self-service mechanism reduces signaling overhead while managing the complexity through structured autonomous decision-making based on detected communication conditions.
2Reliability
If the UE performs autonomous NR RAT deprioritization by releasing connections and redirecting to LTE, then voice call support is ensured and communication reliability improves, but the device complexity and processing requirements increase
Solution Approach 1:
The UE dynamically adjusts its RAT selection and connection management based on real-time detection of communication modes and NR RAT stability. The system transitions between autonomous deprioritization and normal operation based on detected conditions, ensuring voice call support through adaptive decision-making that balances reliability requirements with processing complexity.
3Adaptability or versatility
If the UE continuously monitors communication modes and NR RAT stability to enable autonomous deprioritization, then the ability to maintain voice capabilities and switch to stable RATs improves, but the energy consumption and processing load increase
Solution Approach 1:
The UE performs periodic monitoring of communication modes and NR RAT stability rather than continuous monitoring, enabling autonomous deprioritization decisions at structured intervals. This periodic approach maintains the adaptability to switch between RATs while reducing the energy consumption and processing load associated with constant monitoring.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, in a communication mode, a communication connection with a first radio access technology (RAT) or a second RAT. The UE may receive or identify an indication to deprioritize the first RAT. The UE may perform, based at least in part on the indication to deprioritize the first RAT, an action to deprioritize the first RAT, where the action is based at least in part in the communication mode. Numerous other aspects are described.
