A serving base station (BS) associated with multiple cells may select a set of these cells as candidate cells for a UE and send to the UE a set of candidate PCIs associated with those cells (e.g., one PCI for each cell). The BS may select a subset of the candidate cells to serve to the UE and indicate to the UE the corresponding subset of PCIs. The UE may select a PCI from the set of candidate PCIs (or from the subset of PCIs) to use for obtaining a timing reference for a synchronization signal block (SSB) measurement. The UE may select a PCI based on a defined rule. The UE may select a PCI based on signaling from the BS.

For each PCI in the set of selected PCIs indicated by the dormancy status information as associated with a dormant state, the UE refrains from PDCCH monitoring on a dormant BWP to which the respective PCI transitions. For each PCI in the set of selected PCIs indicated by the dormancy status information as associated with a non-dormant state, the UE performs PDCCH monitoring on a non-dormant BWP to which the respective PCI transitions.
