Abstract: The present invention provides a broadcast message transmission method, a base station and user equipment. The method includes: determining a resource position of a broadcast channel, wherein the broadcast channel occupies M physical resource blocks (PRBs) among m PRBs of a frequency band center of a carrier, m and M are positive integers, M is not greater than m, and m is not greater than the number of the PRBs corresponding to the system bandwidth; mapping the broadcast channel on the resource position; and sending a broadcast message through the broadcast channel. In the embodiments of the present invention, since the broadcast channel occupies M PRBs among m PRBs of a frequency band center of a carrier, by mapping the broadcast channel on the resource position and sending a broadcast message through the broadcast channel, the resource utilization rate of the carrier may be improved.
