Platoon Gateway Bridging C-V2X and DSRC Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles equipped with either C-V2X or DSRC communication protocols face challenges in interworking, preventing effective communication between vehicles with different communication capabilities, leading to inefficiencies in safety message exchange.
Innovation Solution
A platoon-based protocol interworking solution where a vehicle with heterogeneous C-V2X and DSRC capabilities acts as a bridge, facilitating communication between vehicles using only C-V2X or DSRC protocols within a platoon, enabling message summarization and transmission using a second protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles use different communication protocols (C-V2X or DSRC), then each vehicle can communicate effectively within its own protocol ecosystem, but communication between vehicles with different communication capabilities is prevented
Solution Approach 1:
The patent introduces a gateway device as an intermediary that receives messages from vehicles using one protocol (e.g., C-V2X) and forwards them to vehicles using another protocol (e.g., DSRC). The gateway performs protocol conversion, translating message formats between the two protocols to enable cross-protocol communication while maintaining the reliability of each protocol's native communication.
2Loss of information
If all vehicles transmit individual safety messages separately, then complete information is provided to all vehicles, but communication efficiency decreases and network congestion increases
Solution Approach 1:
The patent implements a message aggregation mechanism where multiple individual safety messages from different vehicles are combined into a single consolidated message. The gateway device collects messages from multiple sources, merges their content, and transmits the aggregated information to receiving vehicles, thereby reducing the total number of transmissions while preserving essential safety information.
Solution Approach 2:
The patent segments the communication function into two distinct roles: message generation at the vehicle level and message aggregation/forwarding at the gateway level. This segmentation allows vehicles to focus on generating accurate safety messages while the gateway handles the efficiency-critical task of consolidating and routing messages, separating information completeness from communication efficiency.
3Adaptability or versatility
If a gateway device aggregates and forwards messages between protocols, then protocol interworking is enabled, but device complexity increases
Solution Approach 1:
The gateway device is designed with multi-functionality to handle multiple communication protocols (C-V2X and DSRC) and perform various operations including message reception, protocol conversion, aggregation, and forwarding. By consolidating these diverse functions into a single universal device, the system enables protocol interworking without requiring separate specialized devices for each function, thereby managing complexity through functional integration.

AI summary
Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a process may include receiving, at a network device (e.g., a vehicle or other type of network device), a plurality of messages using a first type of communication protocol, wherein the network device is part of a platoon including a plurality of network devices (e.g., a plurality of vehicles or other network device). The process may include generating, at the network device, a summary message summarizing the plurality of messages. The process may include transmitting the summary message using a second type of communication protocol.
