    Abstract: A first cellular base station transmits a configuration message to a reporting device installed on a high-speed vehicle. The configuration message specifies one or more parameters of a Doppler measurement report. The reporting device performs one or more first Doppler measurements on the first base station and/or one or more second Doppler measurements on a second base station. The reporting device transmits the Doppler measurement report to the first and/or second base stations. The Doppler measurement report may be used by the first and/or second base stations to perform Doppler pre-compensation on transmissions to the reporting device.

    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.
