Problems solved by technology
However, the increase in cell deployment density will lead to more frequent handovers and higher handover rates. In order to ensure business continuity, optimizing the way 5G base stations (gNBs) acquire user location information has become a key point in solving the handover problem.

Embodiment Construction
[0018] The method of the present invention will be further described below in conjunction with specific examples.
[0019] Such as figure 1 As shown, based on the method of measuring user equipment positioning information based on the beam of a single 5G base station, the coverage area of the gNB cell is divided into multiple areas. Send update information, gNB estimates area information and combines it with DoA / AoA Kalman filter to integrate it into mobile user position estimation for positioning. The specific method is:
[0020] (1) The location information of the gNB is known, and it is equipped with an antenna that can perform DoA and AoA estimation, and then divides the cells covered by it into multiple areas (such as figure 1 Show). The division information can be obtained at the gNB from the beginning of the gNB deployment process, and the area size can be static or dynamic. Location information will be estimated by the gNB whenever the mobile user is anywhere with...

The method for measuring the positioning information of the user equipment based on the beam of the single 5G base station comprises the following steps: dividing a coverage area of a 5G base station cell into a plurality of areas; when the user terminal is located at any position in the areas, transmitting a group of reference beams by the 5G base station, identifying the reference beams by the user terminal in cooperation with the 5G base station, and selecting a group of optimal matching beams from the reference beams, and continuously sending the updating signal; and finally, estimating and positioning, by the 5G base station, the position information of the user. In this way, a high-efficiency and high-precision user positioning function is realized by matching the received and transmitted messages with the UE (user terminal) by utilizing a single gNB and equipping an antenna capable of performing DoA (angle of departure) and AoA (angle of arrival) estimation.
Description
technical field [0001] The present invention relates to the field of mobile communication technology, in particular to improving the current gNB method for obtaining location information of mobile users, and a method for measuring user equipment location information based on a beam of a single 5G base station. Background technique [0002] 5G defines three application scenarios: enhanced mobile broadband (eMBB), massive Internet of Things (mMTC) and low-latency highly reliable communications (uRLLC). Among them, eMBB mainly pursues the ultimate communication experience between people, and corresponds to large-traffic mobile broadband services such as 3D / ultra-high-definition video; Sense and data collection as the goal; uRLLC is aimed at applications that require extremely high latency and reliability, such as autonomous driving and mobile medical care. In order to achieve the goal of 5G design, Ultra Dense Network (UDN) technology can achieve a huge improvement in frequenc...
