    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: A method for enhanced autonomous uplink timing adjustment includes determining that a user equipment (UE) is traveling above a predetermined velocity. In response to the determination that the UE is traveling above the predetermined velocity, a maximum aggregate adjustment rate to an uplink timing for the UE and a maximum amount of a magnitude of a timing change to the uplink timing for the UE are determined. The uplink timing for the UE is adjusted based on the maximum aggregate adjustment rate and the maximum amount of the magnitude of the timing change.

    Abstract: Techniques discussed herein can facilitate enhanced radio resource management measurements for wireless technology including New Radio (NR). One example aspect is a baseband processor of a user equipment (UE), including one or more processors configured to receive a measurement link information state link information. The one or more processors are further configured to determine, from the measurement link information, a number of synchronization signal block based measurement timing configurations (SMTCs) (Y) per Rx beam of a number of receive (Rx) beams (N); generate at least one of a subset number of Rx beams (NUE) of the number of Rx beams based on the measurement link information, or an increased number of SMTCs (YUE) of the number of SMTCs corresponding to the number of Rx beams; and perform radio resource management (RRM) measurements according to one or more of the subset number of Rx beams or the increased number of SMTCs.

    Abstract: The disclosure relates to Discontinuous Reception (DRX) based UE behavior. A user equipment (UE) is configured to perform operations comprising: obtaining a first DRX cycle; determining a second DRX cycle at least based on the first DRX cycle and a DRX cycle threshold, wherein the DRX cycle threshold is a highest value of DRX cycle that can support LEO (Low-Earth Orbit) cell measurement; and applying the second DRX cycle, comprising applying the second DRX cycle to measurement of at least one LEO cell of the serving cell and a neighbor cell, wherein at least one of the serving cell and the neighbor cell is a LEO cell.
