Abstract
A UE receives one or more modulation symbols on one or more resource elements prior to an ON duration in a particular DRX cycle in RRC connected mode. The one or more resource elements are allocated to carry a wake-up signal. The UE performs a blind detection of the wake-up signal on the one or more modulation symbols in accordance with a DCI format and a group identifier identifying a group of UEs including the UE. The wake-up signal includes an indication that indicates whether one or more UEs of the group of UEs should monitor a down link control channel in the ON duration. The UE determines whether to operate in a normal state and monitor a down link control channel in the ON duration based on the wake-up signal when the wake-up signal is detected.
