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 based on transmission 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 selection by the UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If transmission format is determined without Tx profile information from higher layer, then transmission can proceed without waiting for configuration, but transmission compatibility with terminals of different versions cannot be ensured
Solution Approach 1:
The patent applies preliminary action by determining the transmission format in advance based on pre-stored transmission format information before actual data transmission occurs. This allows the terminal to immediately transmit data without waiting for dynamic configuration from the higher layer, improving transmission speed while ensuring compatibility through pre-established format rules
Solution Approach 2:
The patent changes the parameter determination approach from dynamic higher-layer configuration to using pre-stored transmission format information. By changing how transmission format parameters are selected (from real-time configuration to pre-defined selection), the system achieves both faster transmission and version compatibility
2Reliability
If transmission format is determined by higher layer configuration, then transmission compatibility is ensured, but transmission delay increases due to configuration waiting time
Solution Approach 1:
The patent eliminates configuration waiting time by performing the transmission format determination in advance and storing it locally. The terminal uses this pre-determined format information immediately when data needs to be transmitted, removing the delay associated with waiting for higher layer configuration while maintaining compatibility
3Adaptability or versatility
If different transmission formats are used for different terminal versions, then version-specific optimization is achieved, but system complexity increases
Solution Approach 1:
The patent applies local quality by storing different transmission format information for different terminal versions in a version-specific manner. Each terminal version has its own pre-configured transmission format parameters stored locally, allowing version-specific optimization without requiring complex global management mechanisms
Solution Approach 2:
The terminal performs self-service by autonomously selecting the appropriate transmission format based on its stored version-specific information without requiring complex external coordination. The terminal independently determines and applies the correct format, reducing system management complexity

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.
