Solution Overview
Problem
Current vehicle-to-everything (V2X) communication technologies face limitations in bandwidth and delays due to environmental factors, leading to inefficient data transmission and reception in car networking, which affects vehicle control.
Innovation Solution
A method and apparatus that identify objects in a road environment, divide them into subsets based on distance from a server device, and generate data packets for transmission to specific client devices within associated regions, optimizing transmission power and frequency for static and moving objects, thereby improving data transmission efficiency and reducing computational overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all collection data from the road environment is transmitted to client devices, then the completeness of information is improved, but the bandwidth consumption increases and transmission delays occur
Solution Approach 1:
The patent segments the road environment into multiple regions and divides collection data into different data sets based on spatial location. Each data set corresponds to a specific region and is transmitted to client devices based on their location, thereby reducing unnecessary bandwidth consumption while maintaining information completeness for relevant clients
Solution Approach 2:
The patent applies local quality by transmitting different data sets to different client devices based on their specific location and service area. Each client receives only the data relevant to its local region, optimizing bandwidth usage while ensuring each device gets the complete information it needs for its specific context
2Reliability
If transmission power is increased to ensure data packet reception, then the reliability of data transmission is improved, but the energy consumption increases
Solution Approach 1:
The patent implements dynamic transmission power adjustment based on the distance between the server device and client devices. The determination module calculates appropriate transmission power levels according to spatial relationships, ensuring reliable data packet delivery while minimizing energy consumption by avoiding excessive power transmission
3Adaptability or versatility
If data is transmitted to all client devices in the coverage area, then the coverage completeness is improved, but the processing overhead for client devices increases
Solution Approach 1:
The patent segments the coverage area into multiple regions and assigns different data sets to different regions. Client devices receive only the data sets corresponding to their specific region, reducing processing overhead while maintaining coverage completeness across the entire service area
Solution Approach 2:
The patent applies local quality by providing different data sets to different client devices based on their location. Each client processes only the data relevant to its local area, reducing computational complexity while ensuring complete coverage of the overall service region through coordinated transmission to multiple devices

AI summary
The present disclosure relates to a method and an apparatus for transmitting and receiving data, a device, and a storage medium. According to an exemplary implementation, a method for transmitting data is provided. In the method, a set of objects in a road environment is identified based on collection data associated with the road environment from a server device. The set of objects is divided into at least one subset based on a distance between each of the set of objects and server devices. For a subset in the at least one subset, a data packet is generated based on a portion of the collection data associated with objects in the subset. The generated data packet is transmitted to at least one client device, the at least one client device being located in a region associated with the first region where the objects in the subset are located.
