AI Technical Summary

Technical Problem

In non-terrestrial networks (NTN) like satellite communications, the long round-trip time (RTT) leads to inefficiencies in HARQ processes, causing reduced throughput, increased PUCCH overhead, and suboptimal link adaptation due to stale ACK/NACK feedback, which disrupts scheduler performance.

Method used

Implementing a method to configure and minimize ACK/NACK feedback from user equipment (UE) by disabling HARQ retransmissions and using triggers based on data packet reception, elapsed time, block error rate (BLER), or network requests to provide sufficient feedback for link adaptation, enabling efficient ACK/NACK reporting.

Benefits of technology

Enhances network throughput and maintains effective link adaptation by optimizing ACK/NACK reporting, reducing overhead and conserving UE battery life while ensuring reliable communication in NTN environments.
