Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing connectivity and data transmission between user equipment and satellite or airborne nodes, particularly in vehicular environments, which require robust and reliable Vehicle-to-Everything (V2X) communications.
Innovation Solution
A system and method for mobile communications that utilize a satellite/airborne interface to enhance V2X communications by maintaining multiple interfaces between user equipment and network nodes, switching based on connectivity states and signal attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terrestrial wireless interfaces (Uu, PC5) are used for V2X communications, then coverage and connectivity are maintained in urban environments, but connectivity is lost in rural or remote areas where terrestrial infrastructure is unavailable
Solution Approach 1:
The system enables user equipment to perform multiple communication functions by supporting both terrestrial wireless interfaces (Uu, PC5) and satellite interfaces through the same device. The UE can selectively use different interfaces based on geographic location and availability, making the communication system universally applicable across urban, rural, and remote areas without requiring separate dedicated devices for each environment.
2Reliability
If multiple communication interfaces are maintained simultaneously, then connectivity redundancy is improved, but device complexity and power consumption increase
Solution Approach 1:
The system dynamically manages multiple communication interfaces by enabling the UE to adaptively switch between terrestrial (Uu, PC5) and satellite interfaces based on real-time conditions such as signal strength, availability, and communication requirements. This dynamic approach maintains connectivity redundancy while avoiding the permanent complexity of simultaneously activating all interfaces, as the UE only engages with available and appropriate interfaces at any given time.
3Adaptability or versatility
If satellite interfaces are added to existing terrestrial interfaces, then coverage in remote areas is extended, but signal quality and latency may deteriorate
Solution Approach 1:
The system uses the UE itself as an intermediary that intelligently selects between terrestrial and satellite interfaces based on communication requirements. For time-sensitive or high-reliability communications, the UE preferentially uses terrestrial interfaces when available. Satellite interfaces serve as a mediator for extended coverage in remote areas where terrestrial infrastructure is absent, accepting potential trade-offs in signal quality and latency only when necessary for maintaining connectivity.

AI summary
A system, method and apparatus for mobile communications including sidelink transmissions is provided. A user equipment (UE) maintains a first interface between the first UE and a radio access network (RAN) infrastructure node, a second interface between the first UE and a second UE and a third interface between the first UE and a satellite node or an airborne node. The UE switches between interfaces according to a current connectivity state and based on signal attributes associated with individual interfaces.
