Abstract: The present invention provides a signal transmission method for a multiple-user multiple-input multiple-output system, includes: in a signal sending time slot, sending a signal to user terminals through each antenna via preset subcarriers in a signal sending time slot; sending a first public information signal to the user terminals through each antenna via the preset subcarriers in a public information sending time slot. According to the technical solution provided by the present invention, the problem that signal transmission delay of a multiple-user multiple-input multiple-output system where a channel changes rapidly is too long is solved.
