AI Technical Summary

Technical Problem

Deterministic transmission schemes in Time-Sensitive Networking (TSN) bridge architectures increase hardware costs and implementation complexity. Existing technologies struggle to guarantee highly reliable, low-latency, and time-determined data transmission while reducing costs and complexity.

Method used

By obtaining the predicted downlink air interface transmission delay and target redundancy version of TSN data packets, the urgency of data packet transmission is determined, and spectrum resources are allocated according to the urgency and threshold to generate target transport blocks, thereby realizing the scheduling and transmission of data packets.

Benefits of technology

While reducing hardware costs and implementation complexity, it ensures highly reliable, low-latency, and time-definite data transmission, thereby improving the reliability and efficiency of data transmission.

Abstract

This invention discloses a downlink data transmission method, device, and medium for deterministic arrival time. Relating to the field of communication technology, the method includes: obtaining the predicted downlink air interface transmission delay and target redundancy version of each TSN data packet in the set of TSN data packets to be transmitted under the current downlink scheduling time slot; determining the transmission urgency of each TSN data packet in the set of TSN data packets to be transmitted based on the predicted downlink air interface transmission delay, target redundancy version, and expected arrival time of each TSN data packet; determining the TSN data packets to be scheduled in the current downlink scheduling time slot based on the transmission urgency and urgency threshold of each TSN data packet in the set of TSN data packets to be transmitted, allocating spectrum resources for them, and generating a target transport block. Through the technical solution of this invention, high reliability, low latency, and deterministic arrival time data transmission can be guaranteed while reducing hardware costs and implementation complexity.
