Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a direct connection interface is used for data packet transmission between terminal devices, then transmission speed is improved, but reliability deteriorates
Solution Approach 1:
The patent segments the data transmission path into multiple independent interfaces: direct connection interfaces (first interface) for high-speed transmission and network device interfaces (second interface) for reliable transmission. By dividing the transmission task across multiple paths, the system achieves both speed and reliability requirements simultaneously.
Solution Approach 2:
The patent changes the transmission parameter by introducing multiple transmission interfaces with different characteristics. The system dynamically selects or combines different interfaces based on transmission requirements, transforming a single-parameter transmission system into a multi-parameter system that can optimize for both speed and reliability.
2Device complexity
If only a direct connection interface is used for data packet transmission, then device complexity is reduced, but transmission performance deteriorates
Solution Approach 1:
The patent segments the transmission system into terminal devices and network devices, with each segment handling specific functions. Terminal devices use simple direct connection interfaces for immediate communication, while network devices provide additional transmission paths when needed, distributing complexity across different system components.
Solution Approach 2:
The patent creates a universal transmission architecture that supports both direct connection mode and network device-mediated mode. The system can adaptively select the appropriate transmission path based on requirements, making the communication system multi-functional and capable of handling different transmission scenarios with a single unified framework.

AI summary
This application provides a communication method, a first terminal device, and a second terminal device. The method includes: transmitting, by a first terminal device, a first data packet to a second terminal device through a first interface, where the first interface is an interface for direct communication between the first terminal device and the second terminal device; and transmitting, by the first terminal device, a second data packet to the second terminal device through a second interface, where the second interface is any one of the following interfaces: an interface for communication between the first terminal device and an LTE network device, an interface for communication between the first terminal device and an NR network device, the interface for direct communication between the first terminal device and the second terminal device, an interface for direct communication between the first terminal device and a relay terminal device in the LTE standard, and an interface for direct communication between the first terminal device and the relay terminal device in the NR standard. This improves performance of transmitting a data packet between the first terminal device and the second terminal device.
