Auxiliary detection signaling sending method

The invention discloses an auxiliary detection signaling sending method. The method comprises the step that: for each base station in a base station group, i.e. a first base station, other base stations in the base station group, except the first base station, respectively send the auxiliary detection signaling on carrier frequency of the first base station. By adopting the technical scheme, the invention can save the signaling cost and decrease the complexity of MS searching, and is beneficial to saving electricity.
