Abstract: Embodiments of the present invention relate to the field of communications technologies and provide a method for transmitting system information, an apparatus, and a system, to reduce a delay in obtaining correct system information by a terminal device. One method includes: generating a system information block SIB, and sending the SIB in N time units of a SIB period, wherein a first time unit of the N time units includes a redundancy version number of the SIB that is set to 0, the SIB period comprises T time unit groups, and the T time unit groups comprise TP SIB candidate sending time unit groups, wherein TP≤T, each of the T time unit groups comprises A time units for a clear channel assessment (CCA), and each of the TP SIB candidate sending time unit groups comprises r SIB candidate sending time units, and wherein N is a total quantity of SIB candidate sending time units comprised in one or more of the TP SIB candidate sending time unit groups that the CCA is successful, and N≤TP×r.

Abstract: This application provides a data transmission method and apparatus. The method includes: determining a first frequency hopping pattern and a second frequency hopping pattern, wherein the first frequency hopping pattern and the second frequency hopping pattern comprises a same index set of N indexes corresponding to N channels; sending, based on the first frequency hopping pattern, data in each time unit of a first time period by using one of the N channels; and sending, based on the second frequency hopping pattern, data in each time unit of a second time period by using one of the N channels, wherein the first period and the second period are consecutive time periods each comprising N time units, each time unit starts and ends at starting times of two adjacent channels.

Abstract: A method includes determining, by a network side device, N fixed channels. The method further includes determining, by the network side device, a first fixed channel from the N fixed channels, sending, by the network side device, a discovery reference signal on the first fixed channel, and performing data transmission on a data channel through frequency hopping. The data channel includes a channel other than the N fixed channels. N is an integer greater than or equal to 2.

Abstract: This application provides a data transmission method, to help increase a data transmission success rate. The method includes: broadcasting, by a network device, first channel information, where the first channel information is used to indicate a channel state of each of N channels, the channel state is that the channel is available or that the channel is unavailable, and N≥1; and determining, by the network device, a channel for frequency hopping transmission based on the channel state of each channel.
