Embodiments of this disclosure provide techniques for signaling in power save mode. In particular, a UE may identify an association between a set of time durations for paging a downlink control indicator (DCI) transmission and a wake up signal (WUS) in a set of WUSs. Paging the DCI is transmitted in a beam sweeping manner and each beam used in each time duration in the set of time durations corresponds to a respective beam used for a WUS transmission in the set of WUSs. The UE monitors a radio link quality of WUSs in the set of WUSs and, based thereon, selects a first WUS in the set of WUSs. The UE identifies a first time duration for DCI page monitoring, the first time duration corresponding to the first WUS. The UE monitors the DCI page during the first time duration.

A method for signaling in power save mode, the method comprising:
The method of claim 1, wherein each of the paging messages is transmitted multiple times over different multi-beam operations.
The method of claim 1, wherein the WUSs are transmitted before a beginning of the paging occasion.
The method of claim 1, wherein a time gap between an end of the transmitting of the WUSs and a beginning of the transmitting of the paging messages is a non-zero time gap.
The method of claim 4, wherein the non-zero time gap is pre-determined in accordance with a radio resource control (RRC) protocol.
The method of claim 1, wherein one or more of the WUSs are transmitted during the paging occasion, each of the WUSs, excluding the one or more WUSs, being transmitted before the associated paging message is transmitted.
The method of claim 1, wherein a time gap between an end of transmitting of each of the WUSs and a beginning of a transmitting of the associated paging message is a non-zero time gap.
The method of claim 1, wherein each succeeding one of the WUSs is transmitted after an elapsed non-zero time gap from a transmission of a preceding one of the WUSs.
The method of claim 1, wherein each of the WUSs further indicates to the UE to monitor the control channel of the respective beam, during the paging occasion, for N consecutive DRX cycles, N being an integer greater than or equal to one.
The method of claim 1, wherein the WUSs include a one-to-N mapping with one or more paging occasions in multiple consecutive DRX cycles, wherein N is an integer greater than or equal to one.
The method of claim 1, wherein the control channel is a physical downlink control channel (PDCCH).
The method of claim 1, wherein each of the WUSs is transmitted over a different respective beam.
The method of claim 1, wherein each of the paging messages is a paging downlink control indicator (DCI).
The method of claim 1, wherein a length of the paging occasion corresponds to one period of beam sweeping in a multi-beam operation.
The method of claim 14, wherein each beam in the multi-beam operation is quasi co-located (QCL'ed) with a corresponding one of the WUSs.
The method of claim 14, wherein multiple beams in the multi-beam operation are quasi co-located (QCL'ed) with one of the WUSs.
The method of claim 14, wherein each beam in the multi-beam operation is a synchronization signal block (SSB) beam.
The method of claim 14, wherein each of the WUSs further indicates to the UE to monitor a control channel of a second different beam in the multi-beam operation for a second associated paging message during a second configured period of the paging occasion of the discontinuous reception (DRX) cycle.
The method of claim 1, wherein each of the WUSs further indicates to the UE that the paging messages are to be transmitted to the UE during the paging occasion.
The method of claim 1, wherein each of the WUSs further indicates to the UE that the paging messages are not to be transmitted to the UE during the paging occasion.
The method of claim 1, wherein each of the WUSs further indicates to the UE an associated identifier (ID) of an intended UE associated with the WUS.
The method of claim 1, wherein at least two of the WUSs are transmitted to the UE using a different frequency resource.
The method of claim 1, wherein at least two of the WUSs are transmitted to the UE using the same frequency resource.
The method of claim 1, wherein at least two of the WUSs are transmitted using the same sequence.
The method of claim 1, wherein at least two of the WUSs are transmitted using a different sequence.
