A method of a user equipment (UE) in a wireless communication system includes receiving configurations for occasions to receive first and second types of low power signals and determining, based on the configurations, a first set of periodic occasions to receive the first type of low power signal and a second set of non-periodic occasions to receive the second type of low power signal. The method further includes receiving the first type of low power signal and the second type of low power signal and performing, based on the first type of low power signal, at least one of a synchronization measurement and a radio resource management (RRM) measurement. ## Claims ### Claim 1 A user equipment (UE) in a wireless communication system, the UE comprising: a transceiver configured to receive configurations for occasions to receive first and second types of low power signals; and a processor operably coupled to the transceiver, the processor configured to determine, based on the configurations: a first set of periodic occasions to receive the first type of low power signal; and a second set of non-periodic occasions to receive the second type of low power signal, wherein the transceiver is further configured to receive the first type of low power signal and the second type of low power signal, and wherein the processor is further configured to perform, based on the first type of low power signal, at least one of a synchronization measurement and a radio resource management (RRM) measurement. ### Claim 2 (depends on 1) The UE of claim 1, wherein the processor is further configured to determine whether to wake up based on the second type of low power signal. ### Claim 3 (depends on 1) The UE of claim 1, wherein the configurations for the occasions to receive the first type of low power signal include at least one of a periodicity, an interval between consecutive occasions, and a number of occasions within the periodicity. ### Claim 4 (depends on 1) The UE of claim 1, wherein: the configurations for the occasions to receive the second type of low power signal include at least one of a time period and an interval between consecutive occasions, and the second set of non-periodic occasions to receive the second type of low power signal are within the time period. ### Claim 5 (depends on 1) The UE of claim 1, wherein the processor is further configured to determine a quasi-co-location (QCL) assumption for receiving the first type of low power signal. ### Claim 6 (depends on 5) The UE of claim 5, wherein each occasion within the first set of periodic occasions to receive the first type of low power signal is quasi-co-located (QCLed) with a synchronization signals and physical broadcast channel (SS/PBCH) block. ### Claim 7 (depends on 6) The UE of claim 6, wherein the SS/PBCH block is determined as an actually transmitted SS/PBCH block based on an indication in a system information block 1 (SIB1). ### Claim 8 A base station (BS) in a wireless communication system, the BS comprising: a processor configured to determine: a first set of periodic occasions to transmit a first type of low power signal; a second set of non-periodic occasions to transmit a second type of low power signal; and configurations for the first and second sets of occasions, wherein the first type of low power signal is for at least one of a synchronization measurement and a radio resource management (RRM) measurement;
