AI Technical Summary

Technical Problem

Terminals cannot uniformly monitor transmission behavior in terrestrial networks (TN) and non-terrestrial networks (NTN), leading to a decline in communication system performance, especially in cells composed of multiple transmit and receive points (TRPs), where transmission monitoring behavior is inconsistent.

Method used

A time determination method is provided, in which a terminal and a network-side device monitor transmission at a specific time based on determining first information. The first information includes a first duration, a first indication, and a second indication, which are used to determine the start point, end point, or duration of the transmission.

Benefits of technology

It enables unified transmission monitoring of terminals under TN and NTN, thereby improving the performance of the communication system.
