description: Physical Cell Identity (PCI) is a unique identifier assigned to each cell in a cellular network. It is used by the base station to identify itself and distinguish it from neighboring cells. The PCI is an essential parameter for ensuring proper functioning of various radio resource management algorithms, such as handover decisions, interference coordination, and mobility management.
explanation: PCI is classified as an Identifier because it serves as a unique code that distinguishes one cell from another in the network, aligning with the context provided from the 3GPP TS 38.331 specification.
