AI Technical Summary

Technical Problem

When terminal devices transmit large-scale sensing and measurement data, existing technologies struggle to transmit data efficiently, resulting in low transmission efficiency.

Method used

The sensed data is divided into multiple Packet Data Convergence Layer Protocol (PDCP) Protocol Data Units (PDUs), and segmented transmission is performed through N PDCP PDUs. This ensures that the data size of each sensed data packet is less than or equal to the maximum data size of the PDCP PDU, and the sensed data is restored at the receiving end according to the indication information.

Benefits of technology

It improves the transmission efficiency of sensing data, enabling the receiving end to effectively recover the sensing data, and is compatible with existing air interface data transmission methods, ensuring the integrity and efficiency of data transmission.

Abstract

A data transmission method and apparatus. The method comprises: for first sensing data corresponding to a same time unit, the first sensing data can be transmitted by determining N PDCP PDUs, wherein one PDCP PDU comprises part of the first sensing data. In this way, segmented transmission of the large-volume first sensing data can be realized, and compatibility with a current air interface data transmission method can be achieved, thereby improving the transmission efficiency of sensing data.
