Abstract:
1. A method for receiving system information (SI) by a user equipment (UE) in a mobile communication system, the method comprising: receiving, by the UE, the SI including first partial bits of a system frame number (SFN) on a broadcast channel (BCH) at a first subframe of a radio frame, the first partial bits of the SFN having an identical value indicating a reference SFN during a predetermined N successive radio frames of a BCH transmission period, where N is a positive integer; and acquiring, by the UE, second partial bits of the SFN for the radio frame, the second partial bits of the SFN having different values in each radio frame of the predetermined N successive radio frames of the BCH transmission period, and the second partial bits indicating an offset, wherein the SFN is calculated based on the first partial bits and the second partial bits.
