Abstract
The embodiments of the present disclosure disclose an information transmission method, a base station and a terminal. The method comprises: configuring at least one type of subcarrier spacing of synchronization signal and physical broadcast channel and symbol numbers occupied by the synchronization signal and the physical broadcast channel by a base station, wherein, the subcarrier spacing of the synchronization signal is 15×2m kHz, the subcarrier spacing of the physical broadcast channel is 15×2n kHz, m and n are both integers in a range of 0 to 5; selecting one configuration for sending the synchronization signal and the physical broadcast channel according to a service time delay requirement; determining frequency domain positions and time domain positions of the synchronization signal and the physical broadcast channel, wherein, the frequency domain positions for sending the synchronization signal and the physical broadcast channel are neighboring each other or at least partially overlap, the time domain positions for sending the synchronization signal and the physical broadcast channel are neighboring each other or partially overlap; sending the synchronization signal and the physical broadcast channel to a terminal according to the selected configuration and the determined frequency domain positions and time domain positions. By means of the present disclosure, the time delay of a terminal accessing a communication area can be reduced.
