In a FDD system one ARFCN number is required for downlink and another for uplink  as downlink and uplink frequencies are different while for TDD system only one ARFCN number is enough as downlink and uplink frequency remains same. Term ARFCN started from GSM and evolved with the new technologies like it was know as UARFCN for UMTS/WCDMA, named as EARFCN for E-UTAR/LTE and now renamed as  NR-ARFCN for...
