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.

The system, method, and apparatus can receive a first test signal from a first cell; receive a second test signal from a second cell; and perform a test based on AOA of the first test signal and the second test signal. At least one of the first test signal and the second test signal can include a channel state information-reference signal (CSI-RS) signal or a synchronization signal block (SSB) signal. The first test signal can include a different number of SSBs transmitted during an Measurement Timing Configuration (MTC) window when compared to the second test signal. The system, method, and apparatus can receive the first test signal and the second test signal in a time division multiple access (TDMA) manner. The first cell can include a serving cell and the second cell can include a neighboring cell of the serving cell. The system, method, and apparatus can receive the first test signal using a main lobe of an antenna and the second test signal using a side lobe of the antenna.

Abstract: A user equipment (UE) device is configured for performing a signal measurement for wireless communication in a new radio (NR) network. The UE is configured to determine a frequency range (FR) of a serving cell configured to send a signal that is measured by the UE using a signal measurement. The UE configures a measurement gap (MG) pattern to perform the signal measurement. Configuring the measurement gap includes determining that the frequency range of the serving cell includes frequencies of a second frequency range (FR2), determining that a measurement object (MO) configuration for the FR2 is available, setting a measurement gap repetition periodicity (MGRP) value for the signal measurement, and setting a measurement gap length (MGL) value for the signal measurement. The UE performs a signal measurement using the MGRP value and the MGL value.
