REFERENCE MEASUREMENT TIMING SELECTION FOR WIRELESS COMMUNICATION MOBILITY

Abstract:

Aspects relate to selecting a physical cell identifier (PCI) that a user equipment (UE) uses to obtain a timing reference for a mobility measurement. 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.
