On-Demand Satellite Information Request Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in non-terrestrial networks (NTNs), face challenges in efficiently managing and broadcasting system information, leading to increased message size and overhead.
Innovation Solution
The implementation of mechanisms that allow user equipment (UE) to request specific system information on demand, enabling the network to provide only the requested information, such as ephemeris, beam pattern, and neighbor satellite information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the network broadcasts all satellite information (ephemeris, beam pattern, neighbor satellite, etc.), then the UE receives complete system information, but the message size and overhead increase significantly
Solution Approach 1:
The patent extracts only the necessary satellite information that the UE requires for basic operation (ephemeris, beam pattern, neighbor satellite information) from the complete system information broadcast. The network identifies and transmits only this subset of information, removing unnecessary data to reduce message size while maintaining functional completeness for the UE.
Solution Approach 2:
The system information is segmented into essential components (ephemeris, beam pattern, neighbor satellite information) that are transmitted to the UE. This segmentation allows the network to send discrete, targeted information blocks rather than a monolithic broadcast, enabling efficient delivery of only the required data elements.
2Quantity of substance
If the network broadcasts a reduced subset of satellite information, then the message size and overhead are reduced, but the UE may lack complete system information
Solution Approach 1:
The UE is equipped with the capability to autonomously determine which satellite information is necessary for its operation. The UE can identify required information types (ephemeris, beam pattern, neighbor satellite information) and request or receive only these specific elements, allowing the system to function with minimal information while maintaining completeness for the UE's needs.
3Adaptability or versatility
If the network provides detailed satellite information to all UEs, then all UEs have access to complete information, but the overhead and resource consumption increase
Solution Approach 1:
The patent applies local quality by providing satellite information tailored to each UE's specific needs and location. Rather than uniformly broadcasting complete information to all UEs, the network delivers customized information sets (ephemeris, beam pattern, neighbor satellite information) appropriate for each UE's operational context, reducing overall network overhead while maintaining adaptability.

AI summary
Apparatus, methods, and computer-readable media for facilitating on-demand ephemeris and beam information requests are disclosed herein. An example method for wireless communication at a UE includes transmitting a request for requested information, the requested information including one or more of system information and satellite information. The example method also includes receiving a response message based on the request, the response message including one or more of: an NTN system information block, satellite information associated with at least one requested communication satellite, and beam information associated with the at least one requested communication satellite.
