Abstract
A positioning method for a user equipment, a data sending method, a device and a user equipment are disclosed. After receiving a positioning service trigger, the method comprises: acquiring a velocity estimate of a UE to be positioned; selecting configuration information of a PRS according to the velocity estimate, setting a PRS sending period of an evolved base station eNB, and sending the PRS sending period to the eNB; sending the configuration information of the PRS to the UE, enabling the UE to receive the PRS sent by the eNB according to the configuration of the PRS and estimate a measurement of RSTD; and receiving the measurement of RSTD sent by the UE, and calculating a geographic position of the UE according to the measurement of RSTD. The embodiments of the disclosure improve effectively the accuracy of positioning the user equipment.
