As shown in Figure 1, the wireless communication system is a cellular mobile communication technology-based communication system that may include several user devices 110 and several base stations 120.

[0056] Here, the user device 110 may be a device that provides voice and / or data connectivity to a user. The user device 110 can communicate with one or more core networks via a Radio Access Network (RAN). The user device 110 may be a sensor device, a mobile phone (also called a "cellular" phone), or an Internet of Things user device, such as a fixed, portable, pocket-sized, handheld, or embedded in a computer. For example, the user device 110 may be a station (STA), subscriber unit, subscriber station, mobile station, remote station, access point, remote user device, access terminal, user terminal, user agent, user device, or user equipment. Alternatively, the user device 110 may be an unmanned aerial vehicle device. Alternatively, the user device 110 may be an in-vehicle device, such as a driving computer with wireless communication capabilities, or a wireless user device of an external driving computer, or may be a roadside device, such as a road light, traffic light, or other roadside device with wireless communication capabilities.

[0057] The base station 120 may be a network-side device in a wireless communication system. Here, the wireless communication system may be the 4th generation mobile communication (4G) system, also referred to as a Long Term Evolution (LTE) system, or the wireless communication system may be a 5G system, also referred to as a new radio system or a 5G NR system. Alternatively, the wireless communication system may be a next-generation system of the 5G system. Here, the access network in the 5G system may be referred to as a New Generation-Radio Access Network (NG-RAN).

Alternatively, the base station 120 may be a base station (gNB) using a centralized-distributed architecture in a 5G system. When the base station 120 employs a centralized-distributed architecture, it typically includes a centralized unit (CU) and at least two distributed units (DUs). The centralized unit is provided with a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Media Access Control (MAC) layer protocol stack, while the distributed units are provided with a Physical (PHY) layer protocol stack. The embodiments of the present disclosure do not limit the specific embodiment of the base station 120.

[0059] A wireless connection can be established between the base station 120 and the user device 110 via a wireless air interface. In different embodiments, the wireless air interface can be a wireless air interface based on a fourth generation mobile communication network technology (4G) standard, or the wireless air interface can be a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface can be a new radio, or the wireless air interface can be a wireless air interface based on a 5G next generation mobile communication network technology standard.

[0061] Here, the above user device can be considered as a terminal device in the following examples.

[0062] In some embodiments, the wireless communication system described above may further include a network management device 130 .

[0063] The base stations 120 are each connected to a network management device 130. Here, the network management device 130 may be a core network device in a wireless communication system. For example, the network management device 130 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC) network.

The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0064] To better understand the technical solution described in any embodiment of the present disclosure, a scenario of locating a terminal according to one embodiment will be first described.

[0065] Referring to Figure 2, the wireless network communication system includes a terminal 01, a base station 02, and a location management function (LMF) 03. Version 16 (R16) of fifth-generation mobile communication technology (5G) introduces various positioning technologies to realize terminal positioning. Among these positioning technologies, some require a positioning reference signal (PRS).

[0066] In one embodiment, the base station sends a positioning reference signal configuration to a positioning management function (LMF), and the positioning management function (LMF) sends a positioning reference signal (PRS) configuration to the terminal, which performs positioning of the terminal based on the positioning reference signal (PRS) configuration.

[0067] In one embodiment, referring to FIG. 3, the positioning management function (LMF) requests observed time difference of arrival (OTDOA) information from the base station through a New Radio Positioning Protocol (NRPPa) message. After receiving this New Radio Positioning Protocol (NRPPa) message, the base station transmits a response message to the positioning management function (LMF). Again, this response message is a New Radio Positioning Protocol (NRPPa) message. This response message includes a positioning reference signal (PRS) configuration. After receiving the positioning reference signal (PRS) configuration, the positioning management function (LMF) can transmit this positioning reference signal (PRS) configuration to the terminal through a Long Term Evolution (LTE) Positioning Protocol (LPP) message; specifically, refer to FIG. 4. In this manner, the positioning management function (LMF) includes the positioning reference signal (PRS) configuration determined by the base station in the Long Term Evolution (LTE) Positioning Protocol (LPP) message transmitted to the terminal.

[0068] In one embodiment, a positioning management function (LMF) provides a positioning system message to a base station, and the base station transmits the positioning system message, where the positioning system message includes a positioning reference signal (PRS) configuration.

[0069] In one embodiment, a positioning reference signal (PRS) configuration is periodically transmitted, and the positioning reference signal (PRS) configuration includes configuration of different parameters, such as periodicity, bandwidth, and pattern. In one embodiment, the positioning reference signal (PRS) parameters must be configured in the base station through operation, administration, and maintenance (OAM). Therefore, the positioning reference signal (PRS) configuration is semi-static, with cell-level parameters configured. Because the positioning reference signal configuration cannot be dynamically changed and different positioning reference signal (PRS) parameters cannot be configured for different terminals, the positioning reference signal (PRS) configuration cannot meet the positioning needs of different terminals.

[0070] As shown in FIG. 5 , this embodiment provides a method for requesting a positioning reference signal (PRS) configuration, which is applied to a first communication node, and includes:

[0071] Step 51: Send a message carrying a recommended positioning reference signal (PRS) setting, where the recommended positioning reference signal (PRS) setting is a positioning reference signal (PRS) setting recommended by the first communication node for positioning the terminal.

[0075] In one embodiment, after receiving the New Radio Positioning Protocol (NRPPa) message carrying the target positioning reference signal (PRS) configuration, the Positioning Management Function (LMF) may transmit the message carrying the target positioning reference signal (PRS) configuration to a second base station if the transmission / reception points (TRPs) performing positioning for the terminal belong to different base stations, where the different base stations include the first base station and the second base station.
