AI Technical Summary
Technical Problem
The existing Automatic Repeat Request (ARQ) mechanism in Radio Link Control (RLC) Acknowledgment Mode (AM) results in increased latency and reduced reliability of critical data, failing to meet millisecond-level latency and reliability requirements.
Method used
The sequence number of key data is pre-embedded in the data packet, and the receiving end uses a fast timer mechanism to monitor the receiving status of key data in advance, reduce status feedback delay, and trigger retransmission in a timely manner.
Benefits of technology
It improved the retransmission response speed of critical data, reduced the status feedback latency, and enhanced the reliability and resource utilization of critical data.

Abstract
Embodiments of the present application provide a wireless communication method and related device, a sending end pre-embeds a sequence number of to-be-sent key data when generating a current transmission data packet, and a receiving end can obtain the sequence number of the key data in advance by analyzing a current received data packet, thereby avoiding monitoring delay for the key data. The receiving end determines that the key data starts to be transmitted or lost through the sequence number of the key data, starts a first timer, a timing duration of the first timer is less than a timing duration of a reassembly timer, and if the key data is not completely received until the first timer expires, immediately returns a status report to the sending end, without waiting for the reassembly timer to expire, thereby reducing a time delay of key data status feedback, shortening a time delay of the sending end perceiving the key data status, and further triggering retransmission of the key data in time, and improving retransmission response of the key data.
