AI Technical Summary

Technical Problem

In the context of 5G NR wireless communication systems, it is challenging for user equipment (UE) to quickly and reliably recognize when Hybrid Automatic Repeat Request (HARQ) feedback is enabled or disabled, particularly in multicast/broadcast services, affecting the reliability of data transmission to multiple terminals.

Method used

The proposed solution involves a terminal and wireless communication method that enables and disables HARQ feedback based on specific fields within the downlink control information, using a control unit to process downlink control information and enable or disable feedback in the downlink channel, ensuring reliable recognition and operation of HARQ feedback timing.

Benefits of technology

This approach allows for efficient and reliable enabling/disabling of HARQ feedback, enhancing the UE's ability to quickly recognize feedback timing and improving the reliability of data transmission in multicast/broadcast services by using existing DCI fields, such as the PUCCH resource indicator (PRI) field.

Abstract

This terminal receives downlink control information and, in data delivery to a plurality of terminals, the terminal enables and / or disables feedback about an automatic repeat request in a downlink channel on the basis of a priority-related field included in the downlink control information.
