Abstract
A base station for performing physical cell identifier (PCI) collision detection. The base station includes at least one processor configured to determine whether a PCI in a radio resource control (RRC) re-establishment message is the same as a PCI used by a cell implemented by the base station. The at least one processor is also configured to determine whether a cell radio network temporary identifier (C-RNTI) in the RRC Re-establishment message is outside a reserved range of C-RNTIs for the cell. The at least one processor is also configured to identify a possible PCI collision for the cell when (1) the PCI in the RRC Re-establishment message is the same as a PCI used by the cell; and (2) the C-RNTI in the RRC Re-establishment message is outside the reserved range of C-RNTIs for the cell.
