Adaptive V2X Transmission Formats for Cross-Version Packet Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face issues with unsuccessful packet reception by V2X terminals and challenges in transmitting and receiving packets between terminals supporting different versions of the wireless communication system.
Innovation Solution
A method and apparatus for wireless communication that involves generating a first message with a determined transmission format based on Tx profile information from a higher layer, allowing for packet transmission and reception between terminals supporting different versions of the wireless communication system, including resource allocation methods by base stations and autonomous resource selection by terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed transmission format is used for V2X messages, then the transmission process is simple, but terminals supporting different versions of the wireless communication system cannot successfully receive packets
Solution Approach 1:
The patent applies dynamics by making the transmission format adaptable rather than fixed. The transmitting terminal dynamically selects between first and second transmission formats based on whether the receiving terminal supports the second format, allowing the system to adjust to different terminal capabilities while maintaining reliable communication
Solution Approach 2:
The patent changes the transmission format parameters based on terminal capability. By switching between different transmission formats (first format for terminals not supporting the second format, second format for terminals that do support it), the system optimizes packet reception success rate while maintaining ease of operation through automated format selection
2Speed
If transmission format is determined without Tx profile information, then the transmission process is fast, but packet reception fails between terminals with different version support
Solution Approach 1:
The patent applies preliminary action by having the transmitting terminal determine the receiving terminal's format support capability in advance before transmission. This allows the transmitting terminal to pre-select the appropriate transmission format, ensuring both fast transmission and reliable reception without requiring complex real-time negotiations
Solution Approach 2:
The patent introduces an intermediary mechanism (capability indication information) that mediates between terminals with different version support. This intermediary allows terminals to exchange capability information and agree on compatible transmission formats, enabling successful communication between terminals with different version support while maintaining transmission speed

AI summary
Provided is a method of performing, by a user equipment (UE), wireless communication in a wireless communication system, the method including generating a first message and transmitting the generated first message. Here, a transmission format for transmitting the first message may be determined depending on whether transmission profile (Tx profile) information is transmitted from an upper layer of the UE.
