Problems solved by technology

At present, 3GPP version 16 (release 16) requires the positioning accuracy to reach the meter level, while the positioning accuracy of previous versions can only reach about 30 meters, which is still far behind the requirements of 5G.
[0003] In new radio (NR), due to the existence of beams, the received power of paths under different beams will also have a large difference
Therefore, the positioning accuracy of network equipment is low and cannot meet the requirements of 5G

Abstract

The invention provides a positioning method and a communication device. When reporting measurement information of a plurality of paths obtained through positioning measurement to network equipment, the terminal equipment associates each path with a positioning reference signal (PRS) resource identifier or related information (such as an angle of a sending beam, a direction of the sending beam andthe like) of a beam corresponding to the PRS resource identifier. The network equipment can acquire the measurement information of each path and can acquire the information of the beam corresponding to each path at the same time, so that the network equipment can be help to improve the positioning precision.

Description

Technical field[0001]This application relates to the field of wireless communication technology, and more specifically, to a method and communication device for positioning.Background technique[0002]Since the relatively early version of Long Term Evolution (LTE), positioning has been an important feature of wireless communication in the third-generation partnership project (3GPP). In an open outdoor scene, the global position system (GPS) technology is used to locate the positioning accuracy requirement of tens of meters. However, the GPS positioning effect is not very satisfactory indoors or in more complex urban areas. With the evolution of 5G technology, the scenarios that need to be considered are also richer, such as drones and the Internet of Things. The emergence of these new scenarios puts forward higher requirements for positioning accuracy and time delay. At present, the 3GPP version 16 (release 16) requires the positioning accuracy to reach the meter level, while the posi...
