Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently communicating with non-terrestrial networks (NTNs) due to limitations in direct access and power consumption, especially when not all devices have clear line-of-sight access or sufficient battery life.
Innovation Solution
A method where wireless communication devices share and synchronize information via peer-to-peer networks to determine the most suitable devices for direct or indirect communication with NTNs, optimizing communication paths and reducing power consumption by leveraging connected devices for improved connectivity and battery life.

Engineering Contradiction Analysis
1Area of stationary object
If all wireless communication devices attempt direct communication with NTN, then communication coverage is improved, but power consumption increases and system complexity increases
Solution Approach 1:
The system segments communication devices into two categories: selected devices that communicate directly with NTN, and non-selected devices that communicate via peer-to-peer networks. This segmentation allows coverage extension without requiring all devices to maintain high-power direct NTN connections, thus reducing overall power consumption while maintaining broad coverage.
Solution Approach 2:
Selected wireless communication devices act as intermediaries or relays between non-selected devices and the NTN. These intermediary devices maintain direct connections with NTN and facilitate communication for other devices through peer-to-peer networks, enabling coverage extension without requiring every device to consume high power for direct NTN access.
2Reliability
If all wireless communication devices attempt direct communication with NTN, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The system divides devices into selected and non-selected groups, where only selected devices implement complex direct NTN communication protocols. Non-selected devices use simpler peer-to-peer communication mechanisms, reducing their device complexity while maintaining communication reliability through the segmented architecture.
Solution Approach 2:
Selected devices serve as intermediaries that handle the complexity of direct NTN communication protocols, authentication, and connection management. Non-selected devices can achieve reliable communication through these intermediaries without implementing complex NTN protocols themselves, thus reducing their device complexity while maintaining reliability.
3Use of energy by moving object
If selected devices are used for direct NTN communication, then power consumption is reduced, but communication stability may worsen when direct access is limited
Solution Approach 1:
The system merges direct NTN communication paths (for selected devices) with peer-to-peer communication paths (for non-selected devices) into a unified communication architecture. This combination allows the system to switch between communication modes dynamically, maintaining stability even when direct NTN access is limited, while keeping overall power consumption low through intelligent path selection.

AI summary
Disclosed are techniques for wireless communication. In an aspect, a wireless communication device may obtain information regarding communication between the set of communication devices and a non-terrestrial network (NTN) and communicate with the NTN. The wireless communication device may communicate with the NTN directly based on the wireless communication device being identified as one of one or more selected wireless communication devices for direct communication with the NTN. The wireless communication device may communicate with the NTN indirectly via a peer-to-peer communication network and the one or more selected wireless communication devices based on the wireless communication device being not identified as any of the one or more selected wireless communication devices for direct communication with the NTN.
