1. A method of wake-up signal monitoring implemented by a user equipment (UE) during a discontinuous reception (DRX) mode, the method comprising:
determining a statistical property of wake-up signals transmitted by the base station;
selectively monitoring a wake-up signal monitoring occasion preceding the on duration of the DRX cycle for a wake-up signal based on the statistical property of the wake-up signals transmitted by the base station;
waking during a corresponding on duration of the DRX cycle and monitoring the downlink control channel when monitoring of the WUS monitoring occasion is skipped;
wherein the statistical property comprises a wake-up signal reception rate; and
wherein selectively monitoring a wake-up signal monitoring occasion comprises selectively monitoring the wake-up signal monitoring occasions depending on the wake-up signal reception rate.
