摘要: A data transmission method in the present application includes: determining, by first UE, a frame structure in a time unit, where the frame structure indicates that N type-1 OFDM symbols and a GP are included in the time unit, and a subcarrier spacing of each type-1 OFDM symbol is Δf1. Therefore, according to the data transmission method and the user equipment in embodiments of the present application, a frame structure in a time unit is determined. The frame structure indicates that N type-1 OFDM symbols and a GP are included in the time unit, and a subcarrier spacing of each type-1 OFDM symbol is Δf1. Therefore, when an NB-IOT system is deployed in an LTE system in an embedded manner, and when NB-IOT UE is sending data, a channel resource of the legacy LTE system can be adequately utilized, and a conflict with a legacy LTE SRS can be avoided.

摘要: This application provides a system message processing method and apparatus. A terminal receives a master information block (MIB), and obtains indication information. The indication information indicates a type of the MIB. In this way, the terminal can process the MIB based on the type of the MIB. In other words, in embodiments of this application, the terminal may decode the MIB based on the type of the MIB. Therefore, the following case is avoided: The MIB is decoded in a fixed manner, and consequently, the MIB cannot be accurately parsed. In this way, communication efficiency is improved.
