    Abstract: Disclosed is a system and method that allows a user equipment (UE) to perform a wireless measurement. The method configures a characteristic of a channel-state information reference signal (CSI-RS) for tracking of the UE. Also disclosed is a system and method to perform radio resource management (RRM) testing. Testing can include: setting a power level of CSI-RS for tracking to a smaller value that a power level of another RRM reference signal; or setting a negative power offset value of the CSI-RS for tracking to a synchronization signal (SS) of the RRM reference signal; or setting a positive power offset value of the CSI-RS for tracking to a physical downlink shared channel (PDSCH) of the RRM reference signal.

    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.

    Abstract: In a general aspect, a user equipment (UE) in a cellular communications network receives a first Synchronization Signal Block (SSB) corresponding to a first cell of the cellular communications network, and a second SSB corresponding to a second cell of the cellular communications network. The UE clarifies a first cell identifier (ID) of the first cell. The UE clarifies a second cell ID of the second cell. The UE determines an SSB measurement accuracy value using the first cell ID and the second cell ID.

    Abstract: An electronic device may receive, from a radio node, a measurement configuration associated with a wireless communication system. In response, the electronic device may perform measurements using narrow beam patterns based at least in part on a network configuration, where the narrow beam patterns are narrower than a wide beam pattern of the electronic device. Furthermore, performing the measurements using the narrow beams pattern may include performing a beam-pattern search up to the network configuration. Then, the electronic device may perform an SCell activation procedure of an SCell with the radio node. Note that the SCell activation procedure may include reporting, to the radio node, CSI of a narrow beam pattern of the SCell that is to be activated, where the narrow beam pattern is narrower than the wide beam pattern of the electronic device, and the narrow beam pattern is based at least in part on the measurements.
