摘要： This application provides a system message transmission method, an apparatus, and a system. A first communications device configures a MIB message, and the MIB message may carry various different information used to transmit a SIB1, for example, any one or more of scheduling information, first information, and an operation mode of a carrier, so that a second communications device receives the SIB1 based on the MIB message. The first communications device may flexibly configure information used to transmit the SIB1. In addition, when configuring the MIB message, the first communications device may consider ensuring, through configuration or implicit indication, that resource locations for transmitting SIB1s of different cells in one period are different. This type of interference isolation mechanism can avoid mutual interference between transmission of SIB1s of different cells, so that transmission reliability of the SIB1s can be improved.

摘要： The present disclosure relates to the field of mobile communication, and in particular, to frequency determining technologies in the field of wireless communication. In a frequency determining method, a base station determines a frequency according to different modes, so that an interval between the frequency and a channel raster is not greater than a particular threshold. Corresponding frequencies are determined by setting different thresholds. According to the technical solutions provided in this application, user equipment may determine, in different modes, a corresponding frequency resource to communicate with a base station.

摘要： A message transmission method and device relating to the field of communications technologies are described that improve an anti-interference capability in message transmission. The method includes generating a scrambling code according to a scrambling code initialization seed, wherein the scrambling code initialization seed meets the following expression: cinit=R·2α7+P·(nfmodk+1)·2b7 and then scrambling a message according to the scrambling code. The method further includes sending the scrambled message to a terminal on a physical downlink shared channel. Because the first time parameter has different values at at least two different moments, scrambling codes determined at the at least two corresponding different moments are different. Therefore, a possibility at which the base station uses a same scrambling code to scramble a same system message repeatedly in a time period is reduced, so that an anti-interference capability in system message transmission is improved.

The method includes generating a scrambling code according to a scrambling code initialization seed, wherein the scrambling code initialization seed meets the following expression: cinit=R·2a7+P·(nf mod k+1)·2b7 and then scrambling a message according to the scrambling code. The method further includes sending the scrambled message to a terminal on a physical downlink shared channel. Because the first time parameter has different values at at least two different moments, scrambling codes determined at the at least two corresponding different moments are different.
