Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple radio access technologies are used for V2X communications, then connectivity performance and reliability are improved, but device complexity and network management complexity increase
Solution Approach 1:
The patent combines multiple radio access technologies (DSRC, LTE, 5G) into a unified multi-RAT communication system. The convergence function integrates these different technologies at the protocol stack level, allowing them to work together as a cohesive system rather than separate independent systems, thereby improving reliability while managing complexity through unified architecture.
Solution Approach 2:
The communication device is designed with multi-functionality to support multiple radio access technologies simultaneously. The device can adaptively select and switch between different RATs based on network conditions, vehicle requirements, and service types, making it universally capable of handling various V2X communication scenarios with a single integrated system.
2Loss of time
If multiple radio access technologies are integrated, then seamless connectivity and ultra-low latency are achieved, but radio resource management complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring multiple radio access technologies and establishing convergence functions in advance. The protocol stacks are prepared and integrated before actual V2X communication begins, allowing rapid switching and seamless connectivity without requiring complex real-time resource management decisions during critical communication events.
3Reliability
If multi-RAT convergence is implemented, then extreme reliability and high data rates are achieved, but interference management complexity increases
Solution Approach 1:
The patent applies local quality by optimizing each radio access technology's protocol stack and communication parameters according to its specific characteristics and requirements. Each RAT is configured with tailored settings for its operating conditions, allowing interference management to be handled at the local level for each technology rather than requiring a single complex global management system.

AI summary
Systems, devices, and techniques for V2X communications using multiple radio access technologies (RATs) are described herein. A communication associated with one or more of the multiple RATs may be received at a device. The device may include a transceiver interface with multiple connections to communicate with multiple transceiver chains. The multiple transceiver chains can be configured to support multiple RATs. Additionally, the multiple transceiver chains may be controlled via the multiple connections of the transceiver interface to coordinate the multiple RATs to complete the communication.
