AI Technical Summary

Technical Problem

Existing vehicle-to-everything (V2X) communication systems face challenges in reliably transmitting Collective Perception Messages (CPMs) due to segmentation methods that result in incomplete environmental models at the receiver, as lost segments cannot be accurately reconstructed.

Method used

The method involves segmenting the surrounding area into sub-regions, ensuring each segment contains a complete environment model, with each segment including all selected information about the sub-region, and transmitting these segments over a communication network to ensure completeness and reliability.

Benefits of technology

This approach allows recipients to reliably construct a complete environmental model, even in the presence of lost segments, enhancing safety and reliability in autonomous driving by providing accurate information about the surrounding area.

Abstract

The invention relates to a method for providing an object message (101) comprising selected information (1001) about a surrounding area of a subscriber in a communication network, comprising the following steps: • Capturing (103) the selected information (1001) about the surrounding area, in particular sensor data, • comparing (105) a calculated or estimated data size (1051) of the object message (101) comprising the acquired information (1001) about the surrounding area with a given maximum data size (1050) of the transmittable object message (1010), • if the calculated or estimated data size (1051) of the object message (101) exceeds the given maximum data size (1050), the method (100) comprises the following steps: ▪ Segmentation (109) of the surrounding area of the subscriber into at least a first sub-area and a second sub-area, ▪ generating (111) a first transmittable object message segment (1110) comprising at least all of the selected information (1002) about the first sub-area, ▪ generating (112) a second transmittable object message segment (1120) comprising at least all of the selected information (1003) about the second sub-area, ▪ Providing (110) the first transmittable object message segment (1110) and the second transmittable object message segment (1120) for transmission over the communication network (102).
