A network-controlled repeater (NCR) may receive configuration information from a base station to configure one or more receive (Rx) beams and corresponding time-domain resources for potential reception from one or more user equipments (UEs). The NCR may monitor for reception of a physical uplink channel or signal from the one or more UEs on the configured one or more Rx beams on the corresponding time-domain resources and determine that the physical uplink channel or signal is not received for at least a threshold amount of time. Additionally, the NCR may determine to refrain from at least one of additional monitoring for reception of the physical uplink channel or signal from the one or more UEs or transmission of one or more synchronization signal block (SSBs) to the one or more UEs for a duration of time.
