Problems solved by technology

However, since the intersection point of the hyperbola is not unique, it is possible that the three sending stations cannot locate the location of the terminal device, and it is necessary to increase the number of sending stations measured by the terminal device, resulting in an increase in the number of sending stations required for estimating the terminal device , the calculation is complex

Abstract

The embodiment of the invention discloses a positioning method and device, which are used for reducing the number of sending stations so as to reduce the calculation complexity of positioning. The method provided by the embodiment of the invention comprises the following steps: a terminal receives positioning auxiliary information sent by a positioning entity, wherein the positioning auxiliary information comprises a cell identifier of a cell where a to-be-measured sending station is located, an identity identifier of the to-be-measured sending station and positioning reference signal configuration information of the to-be-measured sending station; the terminal measures the to-be-measured sending station according to the positioning auxiliary information to obtain a measurement result, andthe measurement result comprises measured positioning reference signal information of the to-be-measured sending station; and the terminal sends the measurement result.

Description

technical field [0001] The present application relates to the communication field, and in particular to a positioning method and device. Background technique [0002] Currently, positioning technologies applied in communication systems include the following methods: enhanced cell identity-based positioning technology (enhanced cell identity, ECID), assisted-global navigation satellite system technology (assisted-global navigation satellite system, A-GNSS) And observed time difference of arrival technology (observedtime difference of arrival, OTDOA). Relatively speaking, OTDOA technology does not need to use GNSS signals, but uses a positioning principle similar to GNSS to measure the time difference between the arrival of positioning reference signals sent by two or more transmission points (transmission points, transmission points) at the terminal device. The position of the terminal is then calculated given the known position of the individual transmitting stations. [0...
