User Equipment Dynamic Emission Mask Configuration for NTN
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment designed for terrestrial communication networks often struggle to operate efficiently in regions with different regulatory and standards bodies, particularly when communicating with non-terrestrial networks, due to varying emission and reception standards.
Innovation Solution
The user equipment is equipped with a processor that configures the transmitter and receiver to conform to regional regulations and standards by applying appropriate emission masks and noise tolerance settings, allowing it to dynamically adjust to different standards as it moves between geographical regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user equipment uses fixed emission masks and noise tolerance settings for terrestrial communication, then communication is efficient in specific regions, but the equipment cannot operate efficiently in regions with different regulatory standards
Solution Approach 1:
The patent implements dynamic emission masks and noise tolerance settings that automatically adapt based on the detected non-terrestrial network. The system transitions from static, region-specific configurations to dynamic, network-based configurations, allowing the user equipment to adjust its receiver characteristics in real-time according to the actual network conditions and regulatory requirements of different regions.
Solution Approach 2:
The patent changes key receiver parameters including emission masks, noise tolerance levels, and frequency offset settings based on the detected non-terrestrial network. By modifying these parameters dynamically rather than using fixed values, the system can comply with different regional regulations (such as ETSI vs. FCC standards) while maintaining communication efficiency across diverse geographical regions.
2Reliability
If user equipment is configured for strict compliance with one regional standard, then regulatory compliance is ensured, but communication efficiency decreases when moving to regions with different standards
Solution Approach 1:
The patent employs feedback mechanisms where the user equipment detects the non-terrestrial network and uses this information to automatically configure appropriate emission masks and noise tolerance settings. This closed-loop approach ensures the system adapts its compliance parameters based on actual network conditions, maintaining both regulatory compliance and communication efficiency without requiring manual reconfiguration when moving between regions.
3Adaptability or versatility
If user equipment uses broad receiver settings to accommodate multiple standards, then adaptability improves, but performance degradation increases due to suboptimal configuration for specific networks
Solution Approach 1:
The patent performs preliminary detection of the non-terrestrial network before establishing communication. This preliminary action allows the system to pre-configure the appropriate emission masks and noise tolerance settings based on the detected network type and regional requirements, ensuring optimal receiver performance from the outset rather than using suboptimal broad settings that may cause degradation.

AI summary
User equipment may configure a transmitter or receiver to conform to regulations or standards of a geographical region to communicate with non-terrestrial networks (e.g., satellite networks). In one embodiment, the user equipment may receive an indication of a regulation or standard to which to conform to from a terrestrial communication node, and apply an emission mask to the transmitter based on the regulation or standard. The user equipment may additionally or alternatively configure the receiver to be compliant with a noise level tolerance of a received signal specified by the regulation or standard. In some embodiments, the user equipment may implement a frequency offset between the received signal and an interfering signal associated with the noise level tolerance that is scaled based at least on a channel bandwidth associated with the desired signal. Moreover, the user equipment may scale the noise level tolerance based on the frequency offset.
