Description

Positioning method and equipment in UE, base station and service center
Technical Field
The present invention relates to transmission schemes for wireless signals in wireless communication systems, and more particularly to methods and apparatus used for positioning.
Background
In a conventional wireless communication system based on a digital modulation scheme, for example, in a 3rd Generation partnership project (3 GPP) cellular system, a UE usually estimates an OTDOA (Observed time difference of Arrival) of downlink signals from a plurality of base stations through a PRS (Positioning reference signal), and reports the result to an E-SMLC (enhanced Mobile Location center) to locate the UE.
In the 5G system, Massive MIMO (Multiple Input Multiple Output) and corresponding BF (Beamforming) techniques are widely adopted, and uplink reference signals processed by BF will have significant directivity, and the currently adopted positioning method will have improved space.
Disclosure of Invention
In the 5G system, a method for implementing positioning of the UE still adopts the OTDOA-based multi-base station positioning technology of the existing system. One significant drawback of this approach, however, is that cooperation of multiple base stations is required to jointly complete the positioning. For a base station and a UE supporting BF, one base station or a TRP (Transmission Reception Point) may configure a large number of antenna ports, and the UE side also configures a plurality of antenna ports. At different times, the base station or the TRP may receive beams with significantly different directivities from the UE through different antenna ports, and estimate a time difference between transmission and reception and corresponding angle information, thereby implementing positioning of the UE.
The present invention provides a solution to the above problems. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.
