Abstract

The invention relates to a positioning reference signal distribution method, a positioning method and a base station resource configuration method. The positioning reference signal distribution method comprises the following steps: receiving motion information sent by a user terminal; obtaining a positioning reference signal resource meeting the positioning precision based on the motion information; acquiring unallocated signal resources in the positioning reference signal resources, and selecting corresponding signal resources from the unallocated signal resources according to a preset rule and allocating the resources to the user terminal; and sending an instruction for activating the selected signal resource to the user terminal. The terminal positioning method comprises the following steps: receiving a positioning request of a user terminal, the positioning request carrying positioning precision; allocating positioning resources to the user terminal according to the positioning reference signal allocation method; receiving a positioning reference signal sent by the user terminal based on the allocated positioning resource; and calculating position information of the user terminal according to the positioning reference signal. By adopting the method, the positioning reference signals can be scientifically distributed to support differentiated positioning services.

Description

technical field

[0001] The present application relates to the field of communication technologies, and in particular to a positioning reference signal allocation method, a positioning method, and a base station resource configuration method. Background technique

[0002] Wireless network terminal positioning services have gradually evolved from the era of 2G (second generation mobile communication) to the era of 5G (fifth generation mobile communication). , the positioning accuracy is getting higher and higher. However, the positioning accuracy based on the mobile communication network is still at the meter level or above the ten meter level, which cannot meet the positioning accuracy requirements of different users in different scenarios. The technical document TS22.261 of the current 5G Release 16 version (Fifth Generation Mobile Communication Version 16) defines the positioning accuracy of different service levels, with the highest accuracy being 0.2 meters.
