1. A method for a user equipment (UE) to monitor for wake-up signals (WUS) transmitted by a network node in a radio access network (RAN), the method comprising:
determining a second WUS resource for use during a first monitoring occasion associated with a WUS group assigned to the UE, based on the following:
an identifier of a first WUS resource, wherein the first and second WUS resources are part of a first number of configured WUS resources for transmission of WUS;
the first number of configured WUS resources; and
a system frame number (SFN) or a hyper-SFN (HSFN) associated with the RAN; and
monitoring for a WUS, from the network node, in the second WUS resource during the first monitoring occasion.
