UE Default Radio Parameters for Non-Terrestrial Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient methods for UE to adapt to non-terrestrial network (NTN) configurations, leading to potential communication failures due to missing radio resource control (RRC) and other configurations.
Innovation Solution
The UE selects a default value for radio parameters based on whether the network node is terrestrial (TN) or NTN, and modifies behavior if necessary configurations like RRC, SDAP, PDCP, RLC, MAC, or physical layer are not received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the UE uses default terrestrial network configurations for NTN communication, then the device complexity is reduced, but communication reliability deteriorates due to configuration mismatches
Solution Approach 1:
The patent applies parameter changes by detecting NTN-specific parameters (orbit type, coverage type, delay values) and modifying radio parameter configurations accordingly. The UE changes timing parameters, frequency parameters, and power parameters based on NTN conditions to ensure reliable communication while maintaining manageable complexity through automated detection and adaptation.
Solution Approach 2:
The patent implements preliminary action by detecting NTN conditions and selecting appropriate default configurations before actual communication occurs. The UE proactively identifies NTN scenarios through parameter detection and pre-configures appropriate settings, preventing communication failures rather than reacting to them after they occur.
2Manufacturing precision
If the UE detects missing RRC or other configurations and waits for network provision, then configuration accuracy is improved, but communication speed deteriorates due to connection delays
Solution Approach 1:
The patent applies self-service by enabling the UE to autonomously detect NTN conditions, identify missing configurations, and select appropriate default values without requiring network provision. The UE independently determines orbital parameters, coverage types, and timing configurations, eliminating waiting delays while maintaining accurate NTN-specific configurations through self-detection and self-configuration.
3Reliability
If the UE applies NTN-specific default configurations, then communication reliability is improved, but device complexity increases due to multiple configuration sets
Solution Approach 1:
The patent applies dynamics by implementing dynamic configuration selection based on real-time NTN condition detection. The UE continuously monitors for NTN indicators (orbit type, coverage type, delay values) and dynamically switches between terrestrial and NTN configurations as needed. This dynamic adaptation ensures reliable NTN communication while managing complexity through context-driven configuration selection rather than static multiple configuration sets.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a default value for a radio parameter used for communicating with a network node based at least in part on whether the network node is a terrestrial network (TN) node or a non-terrestrial network (NTN) node, an orbit type associated with the network node, or a coverage type associated with the network node. The UE may transmit a communication, e.g., to the network node based at least in part on the default value for the radio parameter. Numerous other aspects are described.
