Abstract

A base station (BS) and a method for system information (SI) modification procedure are provided. The method includes transmitting, to a user equipment (UE), downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a paging radio network temporary identifier (P-RNTI), the DCI including an SI modification bit and a public warning system (PWS) notification bit. The DCI enables the UE to perform an SI acquisition procedure in a case that the SI modification bit is set. The DCI enables the UE to acquire at least one of an earthquake and tsunami warning system (ETWS) notification and a commercial mobile alert system (CMAS) notification immediately after the UE determines that the PWS notification bit is set.
