Problems solved by technology
However, in indoor environments, A-GNSS positioning services become difficult due to satellite signal interruption or fading, and the accuracy is difficult to guarantee
With the development of terminal IMU (Inertial Measurement Unit, inertial measurement unit, including gyroscope, accelerometer and magnetometer, which can be used to track position movement), relatively cheap IMU can meet the general positioning requirements, but due to the accumulation of IMU device errors Effect, long-term tracking of users and precise positioning only relying on the terminal IMU become difficult

Embodiment Construction
[0081] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0082] The positioning reference signal allocation method, positioning method, and base station resource configuration method provided in this application can be applied to such as figure 1 shown in the application environment. Wherein, the user terminal 102 communicates with the backend 104 through the network. When the user terminal 102 needs positioning, it can send a positioning request to the backend 104. The positioning request carries a positioning accuracy, so that the backend 104 can configure the corresponding positioning accuracy of the user terminal 102, and o...

The present application relates to a positioning reference signal allocation method, a positioning method, and a base station resource configuration method. The positioning reference signal allocation method includes: receiving motion information sent by the user terminal; obtaining positioning reference signal resources satisfying positioning accuracy based on the motion information; The corresponding signal resources are selected from the resources and allocated to the user terminal; and an instruction for activating the selected signal resources is sent to the user terminal. The terminal positioning method includes: receiving a positioning request from a user terminal, where the positioning request carries positioning accuracy; allocating positioning resources for the user terminal according to a positioning reference signal allocation method; receiving a positioning reference signal sent by the user terminal based on the allocated positioning resources; The signal is calculated to obtain the location information of the user terminal. By adopting the method, the positioning reference signal can be allocated scientifically 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. [0003] Ou...
