A method for transmitting a system information block in a new radio, NR, network, comprising: a) receiving, by a user equipment, UE, indication information sent by a base station, wherein the indication information indicates a transmission period of periodic transmission of a system information block 1, SIB 1, or indicates a transmission location of aperiodic transmission of the SIB 1; and b) receiving, by the UE, based on the indication information, the SIB1 sent by the base station; wherein the receiving indication information sent by the base station comprises: • receiving, by the UE, a first synchronization signal block, SSB, sent by the base station, wherein the first SSB carries information on a physical broadcast channel, PBCH, and the PBCH is used to carry a master information block, MIB, which includes the following fields: a dmrs-TypeA-Position field for determining a position of a demodulation reference signal, a systemFrameNumber field for determining a frame number, a subCarrierSpacingCommon field for determining a data subcarrier spacing, a cellBarred field for determining whether a cell can be accessed, an intraFreqReselection field for performing intra-frequency cell reselection, an ssb-SubcarrierOffset field for determining an offset between an SSB subcarrier and a data subcarrier, and a pdcch-ConfigSIB1 field for determining configuration information of a PDCCH of a SIB 1; and wherein all or some fields of dmrs-TypeA-Position, intraFreqReselection, cellBarred, and subCarrierSpacingCommon indicate the transmission period of the SIB 1; or • receiving, by the UE, downlink control information, DCI, that is of the SIB1 and that is sent by the base station, wherein transmission frames corresponding to 10 ms are combined to several groups and data bits in the DCI indicate a transmission status of the SIB1 in the groups of transmission frames. a) receiving, by a user equipment, UE, indication information sent by a base station, wherein the indication information indicates a transmission period of periodic transmission of a system information block 1, SIB 1, or indicates a transmission location of aperiodic transmission of the SIB 1; and b) receiving, by the UE, based on the indication information, the SIB1 sent by the base station; • receiving, by the UE, a first synchronization signal block, SSB, sent by the base station, wherein the first SSB carries information on a physical broadcast channel, PBCH, and the PBCH is used to carry a master information block, MIB, which includes the following fields: a dmrs-TypeA-Position field for determining a position of a demodulation reference signal, a systemFrameNumber field for determining a frame number, a subCarrierSpacingCommon field for determining a data subcarrier spacing, a cellBarred field for determining whether a cell can be accessed, an intraFreqReselection field for performing intra-frequency cell reselection, an ssb-SubcarrierOffset field for determining an offset between an SSB subcarrier and a data subcarrier, and a pdcch-ConfigSIB1 field for determining configuration information of a PDCCH of a SIB 1; and wherein all or some fields of dmrs-TypeA-Position, intraFreqReselection, cellBarred, and subCarrierSpacingCommon indicate the transmission period of the SIB 1; or • receiving, by the UE, downlink control information, DCI, that is of the SIB1 and that is sent by the base station, wherein transmission frames corresponding to 10 ms are combined to several groups and data bits in the DCI indicate a transmission status of the SIB1 in the groups of transmission frames.
