Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It should be noted that, in the prior art, as shown in fig. 1, LMF (Location Management Function) in a 5G positioning architecture applicable to the next generation radio access network NG-RAN (Next Generation Radio Access Network) is a positioning management functional unit, and is responsible for selecting a positioning method and triggering a corresponding positioning measurement, and can calculate a positioning final result and accuracy; NG-RAN: positioning reference signals may be sent or positioning measurements may be made based on assistance information; the NR-side node may control multiple TRPs (Transmission-Reception Point)/TPs (Transmission Point) to transmit and/or receive a positioning reference signal; UE: positioning reference signals may be transmitted or positioning measurements may be made based on assistance information; positioning end results and accuracy can also be calculated based on the measurement results.

In the prior art, as shown in FIG. 2, the procedure of DL-PRS configuration is: the LMF may obtain DL PRS configuration information transmitted by a certain NR side node through the process shown in fig. 2, including DL-PRS resource configuration of TRP (Transmission-Reception Point) under the NR side node.

In the prior art, as shown in FIG. 3, the procedure of DL-PRS configuration is: the UE may obtain the DL-PRS configuration of the required measurements through the LPP procedure (LMF unsolicited or UE requested mode) shown in fig. 3.

For the current R17 positioning method, the objective is to increase network efficiency, however, the current DL-PRS configuration mode is that the network side node does not intermittently send DL-PRS configuration to the terminal device UE, and even if the UE does not have a positioning requirement at present, the network side node still sends DL-PRS configuration, resulting in lower DL-PRS configuration efficiency. To solve the problem, the embodiment of the application provides a positioning pilot frequency configuration method, which can activate and/or deactivate DL-PRS based on a request by sending a configuration request for requesting to activate and/or deactivate DL-PRS to a positioning management function unit LMF or an access network device, thereby improving network efficiency for configuring DL-PRS.
