The invention provides a positioning method and device, relates to the technical field of wireless communication, and is used for improving the positioning precision. In the method, a first network device can send distance information of a terminal device to a second network device. A first network device may receive first information from a plurality of second network devices. Wherein one piece of first information can comprise phase information of one or more subcarriers of a positioning reference signal of the terminal equipment, and the phase information can be obtained according to distance information of the terminal equipment. The first network device can determine the position information of the terminal device according to the phase information of the terminal device. Based on the above scheme, the first network device can determine the position information of the terminal device according to the phase information of the positioning reference signal of the terminal device reported by the second netwo
