Claim 15:
16. A base station (BS) configured to operate in a wireless communication system supporting NarrowBand Internet of Things (NB-IoT), the BS comprising:
at least one radio frequency (RF) transceiver; and
at least one processor; and
at least one computer memory operably coupled to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations,
wherein the operations include:
transmitting information for configuring a wake up signal (WUS) group for a user equipment (UE); and
transmitting a WUS for the UE based on an index of the WUS group,

wherein the index of the WUS group is changed over time based on a result of a floor function applied to a system frame number (SFN) and a discontinuous reception (DRX) cycle of the UE.
