Embodiment 1

[0292] like Figure 10 Shown, a kind of measurement method of the embodiment of the present invention, this method comprises:

[0293] Step 1001, the terminal determines the first beam reference signal detected by itself, and sends a request message to the local management function LMF entity, wherein the request message includes the first beam information of the first beam reference signal, so that the The LMF entity determines second beam information of a second beam reference signal sent by a neighboring base station that can be detected by the terminal according to the first beam information;

[0294] Step 1002, the terminal receives the first positioning assistance data including the second beam information sent by the LMF entity;

Abstract

The invention relates to the technical field of wireless communication, in particular to a measurement method and device, and aims to solve the problem that a specific scheme for OTDOA measurement bya terminal does not exist in an NR system in the prior art. According to the embodiment of the invention, a terminal determines a detected first beam reference signal and sends a request message to anLMF entity; the terminal receives first positioning auxiliary data which is sent by the LMF entity and contains second beam information of a second beam reference signal; and the terminal measures asecond beam reference signal of an adjacent base station according to the first positioning auxiliary data. Therefore, it is ensured that the LMF entity can accurately provide positioning auxiliary data for the UE according to the first beam information of the first beam reference signal, the time and power consumption for the terminal to search for the second beam reference signal are reduced, and the system performance is further improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a measurement method and equipment. Background technique [0002] Downlink Observed Time Difference of Arrival (Observed Time Difference of Arrival, OTDOA) is a positioning method defined in the 3GPP protocol specification. The basic principle of OTDOA is: the user terminal (User Equipment, UE) measures the downlink reference signal sent from multiple transmission points (Transmission Point, TP) to obtain the reference signal time difference (Reference Signal Time Difference measurement, RSTD) arriving at the UE ) measurement value, and report the RSTD measurement value to the positioning server to locate the position of the UE. [0003] During the OTDOA positioning process, the positioning server needs to obtain OTDOA auxiliary information associated with the cell from the base station (BS) through the positioning protocol specified by 3GPP, such as: physical cel...
