Embodiments of the present invention disclose an
information transmission method, a
base station and a terminal. The method comprises the steps of configuring, by the
base station,
subcarrier spacing of at least one
synchronization signal and a physical broadcast channel and quantities of symbols occupied by the
synchronization signal and the physical broadcast channel, wherein the
subcarrier spacing of the
synchronization signal is 15*2m kilohertz, the
subcarrier spacing of the physical broadcast channel is 15*2n kilohertz, and both m and n are integers less than or equal to 5 and greater than or equal to 0; according to a service
delay demand, selecting one configuration for sending the synchronization
signal and the physical broadcast channel; determining
frequency domain positions and time frequency positions for sending the synchronization
signal and the physical broadcast channel, wherein the
frequency domain positions sending the synchronization
signal and the physical broadcast channel are adjacent or at least some are identical, and the
time domain positions sending the synchronization signal and the physical broadcast channel are adjacent or some are identical; and sending the synchronization signal and the physical broadcast channel to the terminal according to the selected configuration and the determined
frequency domain positions and the
time domain positions. Through adoption of the method,
base station and terminal, the time
delay for accessing the terminal to the
cell is reduced.
