LINK STATE MONITORING METHOD FOR SIDELINK, AND TERMINAL

WIPO Patent Application WO/2021/008227

A1

The present application relates to the technical field of wireless communications, and provides a link state monitoring method for a sidelink, and a terminal. A first terminal sets a timer when monitoring the link state of a sidelink, starts, after determining the link state of the sidelink between the first terminal and a second terminal, the timer corresponding to the sidelink according to a timer starting condition, and determines, during the running of the timer, that the link state of the sidelink is unchanged. In this way, even if there is no periodic RLM signal for measurement on the sidelink, the first terminal can also determine the link state of the sidelink during the running of the timer according to the link state of the sidelink determined when starting the timer, thereby implementing the monitoring of a sidelink state.
