Abstract

The invention discloses a method and device for positioning in UE, in a base station and in a service center. The UE receives K1 wireless signals and then sends a first measurement report; wherein thefirst measurement report comprises K1 pieces of measurement information, and the measurement information aims at one of the K1 wireless signals; the measurement information is used for confirming thetime length, a first antenna port and a first angle; the first antenna port is used for transmitting the wireless signal corresponding to the measurement information; and the time length and the first angle are both related to the first antenna port. According to the invention, through designing the first measurement report, and under the condition of supporting the beam forming base station andUE, the UE positioning under single base station condition is realized through measuring the distance and angle information of different downlink beams arriving at the UE, therefore, the positioning algorithm is simplified, and the accuracy of the UE positioning is improved.

Description

technical field [0001] The present invention relates to a wireless signal transmission scheme in a wireless communication system, in particular to a method and device used for positioning. Background technique [0002] In traditional wireless communication systems based on digital modulation methods, such as 3GPP (3rd Generation Partner Project, Third Generation Partnership Project) cellular systems, UE often estimates downlink signals from multiple base stations through PRS (Positioning Reference Signal, positioning reference signal) OTDOA (Observed Time Difference of Arrival, Observed Time Difference of Arrival), and report the above results to E-SMLC (Enhanced Serving Mobile Location Centre, Enhanced Mobile Station Location Center), so as to realize the positioning of UE. [0003] In the 5G system, Massive MIMO (Multiple Input Multiple Output) and the corresponding BF (Beamforming) technology will be widely used, and the downlink reference signal processed by BF will have...
