Abstract: The present application relates to the technical field of wireless communications, in particular, to a measurement method and device, used for solving the problem in the art that there is no specific solution for a terminal to perform OTDOA measurement in a NR system. In embodiments of the present application, a terminal determines a detected first beam reference signal, and sends a request message to an LMF entity; receive first positioning assistance data comprising second beam information of a second beam reference signal sent by the LMF entity; measure the second beam reference signal of an adjacent base station according to the first positioning assistance data. Therefore, it is ensured that the LMF entity can accurately provide the positioning assistance data to a UE according to first beam information of the first beam reference signal, the time and power consumption of the terminal for searching the second beam reference signal are reduced, and the system performance is further improved.
