Paging opportunity monitoring
This disclosure provides systems, methods, and apparatuses for wireless communication. A user equipment (UE) may acquire a triggering synchronization signal block (SSB), which enables the UE to monitor for a floating Type-2 physical downlink control channel (PDCCH) and to determine a subset of paging occasions (POs) to monitor. Or, the UE may monitor for a fixed Type-2 PDCCH, where the UE does not require a triggering signal to monitors POs. In another aspect, the UE may monitor for a paging transmission during a monitoring period. The UE may determine the monitoring period based on received signaling. The UE may receive the signaling, during the monitoring period, indicating that the monitoring period is to be ended before a scheduled end of the monitoring period. In this way, the UE may support a continuity requirement associated with downlink reference signaling (DRS) and may support reception of paging in a shared channel.
