AI Technical Summary

Technical Problem

In 5G new wireless access technology systems, window blocking issues lead to reduced data transmission rates and increased latency, especially in RLC layer acknowledgment mode, where existing technologies struggle to effectively address the problem.

Method used

A variable-size send and receive window mechanism is adopted, which flexibly adjusts the window size in RLC layer acknowledgment mode. Data packet transmission is optimized by receiving and sending status reports to ensure that data packets can be acknowledged and received in a timely manner and reduce data backlog.

Benefits of technology

It improves data transmission rate, reduces latency and packet loss, enhances data transmission reliability and flexibility, and solves the window blocking problem.

Abstract

This application provides a communication method and a communication apparatus. The method includes: a first device, while in acknowledgement mode at the Radio Link Control (RLC) layer, sending a first data packet to a second device based on a transmission window; the first data packet is an RLC layer data packet, and the size of the transmission window is variable. This method can solve window blocking, improve data transmission rate, and reduce latency.
