Embodiment Construction

[0071] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0072] Aiming at the problem of low positioning accuracy of the method currently defined by 3GPP to determine the UE position by measuring the reference signal of the wireless communication system itself, the embodiments of the present application propose a UE positioning method based on the measured value of the carrier signal phase of the 3GPP wireless communication system itself. In this method, the transmitting end of the signal in the 3G...

Abstract

The present application discloses a positioning method and device to improve positioning accuracy. The positioning method provided by the present application includes: determining an integer ambiguity by using a positioning measurement value provided by a receiving end of a positioning reference signal; wherein, the positioning measurement value includes: At least the phase measurement value obtained by measuring the carrier positioning reference signal C-PRS sent by the two carrier frequencies, the constructed phase measurement value; the terminal position is determined by the integer ambiguity.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a positioning method and device. Background technique [0002] 3GPP defines a variety of terminal (UE) positioning methods by measuring the self-positioning reference signal of the 3GPP wireless communication system, such as observed time difference of arrival (Observed Time Difference Of Arrival, OTDOA), uplink observed time difference of arrival (Uplink observed Time Difference Of Arrival, UTDOA) and so on. The characteristics of these methods are that the positioning is based on the positioning reference signal (Positioning Reference Signal, PRS) of the wireless communication system itself, and can work in an environment where the reference signal outside the network cannot be received. But the common problem of these localization methods is low localization accuracy. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a...
