Abstract:
An approach is described for a user equipment (UE), wherein the UE includes radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry receives a reference signal from a source device via a radio link, wherein the reference signal is one of the synchronization signal block (SSB) signal or channel state information reference signal (CSI-RS). The processor circuitry measures a quality of the reference signal, and measures an evaluation time of the reference signal. The processor circuitry determines a first indicator of the radio link based on the quality of the reference signal, and determine a second indicator of the radio link based on the evaluation time of the reference signal. The processor circuitry then determines a status of a connection of the radio link based on the first indicator and the second indicator of the radio link, and generate a message based the status of the connection. The radio front end circuitry then transmits the message to the source device.
