Abstract: A network device for locating performing following operations: determining a base station set and an auxiliary UE set that participate in locating of to-be-located target UE; receiving from the to-be-located target UE, a first RSTD set of positioning reference signals PRSs sent by any two base stations in the base station set to the to-be-located target UE, and a second RSTD set of a PRS sent by any auxiliary UE in the auxiliary UE set to the to-be-located target UE and a PRS sent by a reference base station in the base station set to the to-be-located target UE; and determining location information of the plurality of to-be-located UEs based on the first RSTD set, the second RSTD set, and location information of base stations included in the base station set. Locating accuracy and flexibility can be improved.
