Abstract:
1. A method for sending auxiliary detection signaling, each base station in a base station group respectively determining itself as a first base station, comprising: notifying, by a first base station, through a backhaul network other base stations in the base station group of a location of a time-frequency resource for sending auxiliary detection signaling at a carrier frequency of the first base station; or notifying, by an upper-layer network element of base stations in the base station group, all base stations in the base station group of a location of a time-frequency resource for sending auxiliary detection signaling at a carrier frequency of a first base station; notifying, by the first base station, through a broadcast channel a terminal covered by the first base station of the location of the time-frequency resource; respectively sending, by any one of other base stations in the base station group, auxiliary detection signaling at the carrier frequency of the first base station to the terminal covered by the first base station according to the location of the time-frequency resource; receiving, by the terminal covered by the first base station, at the carrier frequency all or part of the auxiliary detection signaling from the other base stations according to the location of the time-frequency resource, and determining a target base station to be switched to according to the received auxiliary detection signaling.
