AI Technical Summary

Technical Problem

In modern wireless communication systems, time-critical applications address the reliability and resource optimization of data transmission within the lifetime, especially in the face of packet loss and errors. Existing FEC and ARQ mechanisms struggle to meet stringent reliability and resource efficiency requirements.

Method used

A dual-mode transmission mechanism is adopted, including a first transmission mode and a second transmission mode. The first mode ensures basic reliability with low resource requirements, while the second mode is activated when the time to live is approaching, increasing transmission resources and reliability measures, such as retransmission, different modulation and coding, and resource allocation, to ensure successful data transmission.

Benefits of technology

Improve the reliability of data transmission and the efficiency of resource utilization before the time of survival, avoid communication service interruptions, and meet the stringent requirements of time-critical applications.

Abstract

Radio device, method of operating a radio device. A method of operating a transmitting radio device of a radio communication network is provided, wherein the method comprises transmitting (102) first data towards a receiving radio device according to a first transmission mode, determining (104) a last reception time when a positive acknowledgement is received from the receiving radio device, the positive acknowledgement indicating a successful reception of the transmitted first data at the receiving radio device side, and transmitting (106) second data towards the receiving radio device according to a second transmission mode, wherein the second transmission mode is activated upon expiry of a first transmission mode time period since the determined last reception time.
