Embodiment 1

[0292] Such as 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 present invention relates to the technical field of wireless communication, in particular to a measurement method and equipment, which is used to solve the problem of disclosing a specific scheme for OTDOA measurement by a terminal in an NR system existing in the prior art. In the embodiment of the present invention, the terminal determines the detected first beam reference signal, and sends a request message to the LMF entity; receives the first positioning assistance data sent by the LMF entity and includes the second beam information of the second beam reference signal; according to the first positioning The auxiliary data measures second beam reference signals of neighboring base stations. This ensures that the LMF entity can accurately provide positioning assistance data to the UE according to the first beam information of the first beam reference signal, and reduce the time and power consumption of the terminal searching for the second beam reference signal, further improving system performance.

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...
