For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0052] 5G (5th Generation Mobile Communication Technology) New Radio (NR) introduces various positioning technologies for locating terminal devices. For uplink positioning and hybrid uplink / downlink positioning, uplink positioning reference signals sent by the terminal device to the network device are required for positioning. The uplink positioning reference signal is a Sounding Reference Signal (SRS). The network device must first configure the uplink positioning reference signal for the terminal device before it can receive the signals sent by the terminal device. The network device configures the uplink positioning reference signal for the terminal device by sending uplink positioning reference signal configuration messages. This configuration includes the time and frequency resources used by the terminal device when sending the uplink positioning reference signal.

[0053] In Release 16 (R16), the following method for terminal device location based on SRS was introduced:

[0054] • Enhanced community identity document (ID) location method;

[0055] • Uplink time difference of arrival positioning method;

[0056] • Multi-community round-trip travel time location method;

[0057] • Uplink Angle of Arrival (AHA) Positioning Method.

[0058] The above method requires the use of an uplink positioning reference signal. In R16, when locating a terminal device using the above method, the terminal device needs to be in a Radio Resource Control (RRC) connected state, which results in higher power consumption for the terminal device.

[0059] In Release 17 (NR), location services for terminal devices in RRC inactive state are supported. While in RRC inactive state, a terminal device can send an uplink location reference signal to the network device. Specifically, when the network device transitions the terminal device from RRC connected state to RRC inactive state, it configures the uplink location reference signal for the terminal device via an RRC release message. The detailed configuration of the uplink location reference signal is contained in the Location Reference Signal Radio Resource Control Inactive State Configuration (srs-PosRRC-InactiveConfig) of the RRC release message. Furthermore, if the terminal device performs cell reselection, it needs to release the uplink location reference signal configured by the network device, i.e., release the uplink location reference signal configuration. For example, after performing cell reselection, the terminal device will delete the locally saved uplink location reference signal configuration.

[0060] In the current NR architecture, the process of configuring uplink positioning reference signals for terminal devices is as follows: The Location Management Function (LMF) network element sends a request message to the base station via New Radio Positioning Protocol A (NRPPa) messages, requesting the base station to configure uplink positioning reference signals for the terminal devices. The base station determines the uplink positioning reference signal configuration and sends it to the terminal devices via RRC messages, thereby configuring the uplink positioning reference signals for the terminal devices. Additionally, the base station also sends the uplink positioning reference signal configuration sent to the terminal devices to the LMF network element.

[0061] When a terminal device in RRC inactive state undergoes cell reselection, it releases the uplink positioning reference signal configured by the base station. Therefore, the uplink positioning reference signal needs to be reconfigured for the terminal device. Currently, the uplink positioning reference signal is configured for the terminal device using the aforementioned scheme: the LMF (Local Management Function) element requests the base station to configure the uplink positioning reference signal for the terminal device. In this scheme, the LMF element is unaware that the terminal device has undergone cell reselection and released the uplink positioning reference signal configuration. Therefore, the LMF element cannot immediately request the base station to reconfigure the uplink positioning reference signal for the terminal device after the terminal device releases the saved uplink positioning reference signal configuration. This increases the delay in configuring the uplink positioning reference signal for the terminal device, thereby increasing positioning latency.

[0062] The method provided in this application embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the network device and / or LMF network element, can realize the immediate configuration of the uplink positioning reference signal for the terminal device according to the request of the terminal device when the terminal device releases the saved uplink positioning reference signal configuration. This can reduce the time delay of configuring the uplink positioning reference signal for the terminal device, thereby reducing the positioning delay and improving the flexibility of configuring the uplink positioning reference signal.

[0063] Figure 1 A schematic diagram of the system architecture of a communication system provided in one embodiment of this application is shown. This system architecture may include: a terminal device 10, an access network device 20, and a core network device 30.

[0064] Terminal device 10 can refer to UE (User Equipment), access terminal equipment, user unit, user station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, wireless communication equipment, user agent, or user device. Optionally, terminal equipment can also be a cellular phone, cordless phone, SIP (Session Initiation Protocol) phone, WLL (Wireless Local Loop) station, PDA (Personal Digital Assistant), handheld device with wireless communication function, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal equipment in 5GS (5th Generation System), or terminal equipment in the future evolved PLMN (Public Land Mobile Network), etc., and this application embodiment is not limited to these. For ease of description, the devices mentioned above are collectively referred to as terminal equipment. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed within the cell managed by each access network device 20.

[0065] Access network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal device 10. Access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with access network device functionality may differ; for example, in a 5G NR system, it is called gNodeB or gNB. As communication technologies evolve, the name "access network device" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functionality to terminal device 10 are collectively referred to as access network devices. Optionally, a communication relationship can be established between terminal device 10 and core network device 30 through access network device 20. For example, in an LTE system, access network device 20 may be one or more eNodeBs within an EUTRAN (Evolved Universal Terrestrial Radio Access Network); in a 5G NR system, access network device 20 may be one or more gNBs within an RAN.

[0066] The core network equipment 30 primarily functions to provide user connectivity, manage users, and bear services, serving as an interface to external networks. For example, core network equipment in a 5G NR system may include AMF (Access and Mobility Management Function) entities, UPF (User Plane Function) entities, SMF (Session Management Function) entities, and Location Management Function (LMF) entities. Access network equipment 20 and core network equipment 30 can be collectively referred to as network equipment. In this embodiment, core network equipment 30 is used as an example of an LMF network element for illustration.

[0067] In one example, access network device 20 and core network device 30 communicate with each other via some over-the-air technology, such as the NG interface in a 5G NR system. Access network device 20 and terminal device 10 communicate with each other via some over-the-air technology, such as the Uu interface.

[0068] Figure 2 A flowchart illustrating a method for configuring an uplink positioning reference signal according to an embodiment of this application is shown. This method can be applied to... Figure 1 In the terminal device shown, the method includes:

[0069] Step 202: Send a request message to the network device and / or LMF network element.

[0070] This request message is used to request network devices and / or LMF network elements to configure an uplink positioning reference signal for the terminal device. For example, configuring an uplink positioning reference signal for the terminal device refers to configuring the terminal device to send an uplink positioning reference signal. This configuration is used by the terminal device to send the uplink positioning reference signal; for example, the configuration includes the time-frequency resources used by the terminal device to send the uplink positioning reference signal. Optionally, the request message also carries the reason why the terminal device requests the uplink positioning reference signal.

[0071] Optionally, the terminal device will send the above request message to the network device and / or LMF network element if at least one of the following conditions is met:

[0072] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0073] • The uplink positioning reference signal stored in the terminal device has been activated;

[0074] • The uplink positioning reference signal stored by the terminal device is a periodic uplink positioning reference signal.

[0075] For example, the above conditions include at least one of the following conditions:

[0076] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0077] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device has been activated;

[0078] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device is a periodic uplink positioning reference signal.

[0079] The phrase "the uplink positioning reference signal stored by the terminal device has expired" refers to the current uplink positioning reference signal configured by the terminal device becoming invalid. This can be interpreted as the uplink positioning reference signal configuration stored by the terminal device becoming invalid. For example, the terminal device may have released its stored uplink positioning reference signal configuration. For instance, a cell reselection may have occurred, causing the terminal device to release its stored uplink positioning reference signal configuration. Optionally, releasing the stored uplink positioning reference signal configuration means that the terminal device deletes the stored uplink positioning reference signal configuration from its local storage.

[0080] When a terminal device sends a request message to a network device, the network device responds to the request message, determines the uplink positioning reference signal configuration for the terminal device, and sends it to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, the network device may also send its determined uplink positioning reference signal configuration to the LMF network element. This network device belongs to the serving cell of the terminal device.

[0081] When a terminal device sends a request message to an LMF (Local Modem) network element, the LMF network element responds to the request message, requesting the network device to configure an uplink positioning reference signal for the terminal device. The network device responds to the LMF network element's request, determines the uplink positioning reference signal configuration for the terminal device, and sends it to the LMF network element. The LMF network element then sends the uplink positioning reference signal configuration determined by the network device to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, in this case, the network device can also respond to the LMF network element's request, determine the uplink positioning reference signal configuration for the terminal device, and send it directly to the terminal device. The network device will also send its determined uplink positioning reference signal configuration to the LMF network element. Optionally, the aforementioned network device belongs to the serving cell of the terminal device.

[0082] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the network device and / or LMF network element, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the terminal device's request when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the time delay in configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0084] Step 302: Receive the request message sent by the terminal device.

[0085] This request message is used to request the network device to configure an uplink positioning reference signal for the terminal device. For example, configuring the uplink positioning reference signal for the terminal device refers to configuring the uplink positioning reference signal to be sent by the terminal device. This uplink positioning reference signal configuration is used by the terminal device to send the uplink positioning reference signal; for example, the uplink positioning reference signal configuration includes the time-frequency resources used by the terminal device to send the uplink positioning reference signal. Optionally, the request message also carries the reason why the terminal device requests the uplink positioning reference signal.

[0086] When a terminal device sends a request message to a network device, the network device responds to the request message, determines the uplink positioning reference signal configuration for the terminal device, and sends it to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, the network device may also send its determined uplink positioning reference signal configuration to the LMF network element. This network device belongs to the serving cell of the terminal device.

[0087] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the network device, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the request of the terminal device when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the latency of configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0088] Figure 4 A flowchart illustrating a method for configuring an uplink positioning reference signal according to an embodiment of this application is shown. This method can be applied to... Figure 1 In the core network device shown, the method includes:

[0089] Step 402: Receive the request message sent by the terminal device.

[0090] This request message is used to request the LMF network element to configure an uplink positioning reference signal for the terminal device. For example, configuring the uplink positioning reference signal for the terminal device refers to configuring the uplink positioning reference signal to be sent by the terminal device. This uplink positioning reference signal configuration is used by the terminal device to send the uplink positioning reference signal; for example, the uplink positioning reference signal configuration includes the time-frequency resources used by the terminal device to send the uplink positioning reference signal. Optionally, the request message also carries the reason why the terminal device requests the uplink positioning reference signal.

[0091] When a terminal device sends a request message to an LMF (Local Modem) network element, the LMF network element responds to the request message, requesting the network device to configure an uplink positioning reference signal for the terminal device. The network device responds to the LMF network element's request, determines the uplink positioning reference signal configuration for the terminal device, and sends it to the LMF network element. The LMF network element then sends the uplink positioning reference signal configuration determined by the network device to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, in this case, the network device can also respond to the LMF network element's request, determine the uplink positioning reference signal configuration for the terminal device, and send it directly to the terminal device. The network device will also send its determined uplink positioning reference signal configuration to the LMF network element. Optionally, the aforementioned network device belongs to the serving cell of the terminal device.

[0092] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the LMF network element, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the terminal device's request when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the time delay in configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0093] Figure 5 A flowchart illustrating a method for configuring an uplink positioning reference signal according to an embodiment of this application is shown. This method can be applied to... Figure 1 In the terminal device shown, the method includes:

[0094] Step 502: Send a request message to the network device.

[0095] This request message is used to request the network device to configure an uplink positioning reference signal for the terminal device. For example, configuring an uplink positioning reference signal for the terminal device refers to configuring the terminal device to send an uplink positioning reference signal. This uplink positioning reference signal configuration is used by the terminal device to send the uplink positioning reference signal, and for example, the uplink positioning reference signal configuration includes the time-frequency resources used by the terminal device to send the uplink positioning reference signal.

[0096] Optionally, the request message also carries the reason why the terminal device requests the uplink positioning reference signal. The reason why the terminal device requests the uplink positioning reference signal includes at least one of the following:

[0097] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0098] • The terminal device experienced a cell reselection.

[0099] Optionally, the terminal device will send the above request message to the network device if at least one of the following conditions is met:

[0100] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0101] • The uplink positioning reference signal stored in the terminal device has been activated;

[0102] • The uplink positioning reference signal stored by the terminal device is a periodic uplink positioning reference signal.

[0103] For example, the above conditions include at least one of the following conditions:

[0104] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0105] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device has been activated;

[0106] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device is a periodic uplink positioning reference signal.

[0107] The phrase "the uplink positioning reference signal saved by the terminal device has expired" refers to the current uplink positioning reference signal configured by the terminal device becoming invalid. This can be interpreted as the uplink positioning reference signal configuration saved by the terminal device becoming invalid. For example, the terminal device may have released its saved uplink positioning reference signal configuration. For instance, a cell reselection may have occurred, causing the terminal device to release its saved uplink positioning reference signal configuration. Optionally, releasing the saved uplink positioning reference signal configuration means that the terminal device deletes the saved uplink positioning reference signal configuration from its local storage. Optionally, the uplink positioning reference signal saved by the activated terminal device may be a semi-persistent uplink positioning reference signal or an aperiodic uplink positioning reference signal.

[0108] Optionally, the request message sent by the terminal device to the network device is carried in the RRC recovery request message.

[0109] Step 504: Receive uplink positioning reference signal configuration sent by network device.

[0110] The uplink positioning reference signal configuration is determined by the network device in response to a request message from the terminal device. When the terminal device sends a request message to the network device, the network device responds by determining the uplink positioning reference signal configuration for the terminal device and sending it to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, the network device may also send its determined uplink positioning reference signal configuration to the LMF network element. This network device belongs to the serving cell of the terminal device.

[0111] Optionally, the uplink positioning reference signal configuration sent by the network device to the terminal device is carried in an RRC message. This RRC message includes at least one of an RRC release message, an RRC reconfiguration message, and an RRC setup message. The uplink positioning reference signal configuration sent by the network device to the LMF network element is carried in an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0112] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the network device, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the request of the terminal device when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the latency of configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0113] Figure 6 A flowchart illustrating a method for configuring an uplink positioning reference signal according to an embodiment of this application is shown. This method can be applied to... Figure 1 In the terminal device shown, the method includes:

[0114] Step 602: Send a request message to the LMF network element.

[0115] This request message is used to request the network device to configure an uplink positioning reference signal for the terminal device. For example, configuring an uplink positioning reference signal for the terminal device refers to configuring the terminal device to send an uplink positioning reference signal. This uplink positioning reference signal configuration is used by the terminal device to send the uplink positioning reference signal, and for example, the uplink positioning reference signal configuration includes the time-frequency resources used by the terminal device to send the uplink positioning reference signal.

[0116] Optionally, the request message also carries the reason why the terminal device requests the uplink positioning reference signal. The reason why the terminal device requests the uplink positioning reference signal includes at least one of the following:

[0117] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0118] • The terminal device experienced a cell reselection.

[0119] Optionally, the terminal device will send the above request message to the LMF network element if at least one of the following conditions is met:

[0120] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0121] • The uplink positioning reference signal stored in the terminal device has been activated;

[0122] • The uplink positioning reference signal stored by the terminal device is a periodic uplink positioning reference signal.

[0123] For example, the above conditions include at least one of the following conditions:

[0124] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0125] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device has been activated;

[0126] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device is a periodic uplink positioning reference signal.

[0127] The phrase "the uplink positioning reference signal saved by the terminal device has expired" refers to the current uplink positioning reference signal configured by the terminal device becoming invalid. This can be interpreted as the uplink positioning reference signal configuration saved by the terminal device becoming invalid. For example, the terminal device may have released its saved uplink positioning reference signal configuration. For instance, a cell reselection may have occurred, causing the terminal device to release its saved uplink positioning reference signal configuration. Optionally, releasing the saved uplink positioning reference signal configuration means that the terminal device deletes the saved uplink positioning reference signal configuration from its local storage. Optionally, the uplink positioning reference signal saved by the activated terminal device may be a semi-persistent uplink positioning reference signal or an aperiodic uplink positioning reference signal.

[0128] Optionally, the terminal device sends a request message to the LMF network element in at least two of the following ways:

[0129] For cases where request messages are sent from network devices to LMF network elements:

[0130] The terminal device sends a request message to the LMF network element via the network device based on an RRC message, such as an RRC recovery request message. In other words, the network device transparently transmits the request message sent by the terminal device to the LMF network element. During this process, the terminal device sends a request message to the network device based on the RRC recovery request message. The RRC recovery request message carries uplink information transfer (UL information transfer), which in turn carries the request message. After receiving the aforementioned information from the terminal device, the network device sends the uplink information transfer to the LMF network element. Optionally, the uplink information transfer refers to uplink non-access stratum transport (NAS transport). Optionally, the network device that transparently transmits the terminal device's request message may or may not belong to the terminal device's serving cell.

[0131] For the case where request messages are sent directly to LMF network elements via the LTE Positioning Protocol (LPP):

[0132] When a terminal device sends a request message directly to an LMF network element, the request message sent by the terminal device to the LMF network element is carried in an LPP message.

[0133] It should be noted that the terminal device can also send request messages to the LMF network element in other ways. The above implementation methods are only used as examples and are not intended to limit the solutions provided in the embodiments of this application.

[0134] Step 604: Receive and configure the uplink positioning reference signal sent by the LMF network element.

[0135] When a terminal device sends a request message to an LMF (Local Modem) network element, the LMF network element responds to the request message, requesting the network device to configure an uplink positioning reference signal for the terminal device. The network device responds to the LMF network element's request, determines the uplink positioning reference signal configuration for the terminal device, and sends it to the LMF network element. The LMF network element then sends the uplink positioning reference signal configuration determined by the network device to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, the aforementioned network device belongs to the serving cell of the terminal device.

[0136] Optionally, the uplink positioning reference signal configuration sent by the LMF network element to the terminal device is carried in the LPP message. The LMF network element requests the network device to configure the uplink positioning reference signal for the terminal device via an NRPPa message. The network device sends its determined uplink positioning reference signal configuration to the LMF network element via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0137] Step 606: Receive uplink positioning reference signal configuration sent by network device.

[0138] When a terminal device sends a request message to an LMF network element, the LMF network element responds to the request message, requesting the network device to configure an uplink positioning reference signal for the terminal device. The network device responds to the LMF network element's request, determines the uplink positioning reference signal configuration for the terminal device, and directly sends it to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, the network device may also send its determined uplink positioning reference signal configuration to the LMF network element. Optionally, the aforementioned network device belongs to the serving cell of the terminal device.

[0139] Optionally, the LMF network element requests the network device to configure the uplink positioning reference signal for the terminal device via an NRPPa message. The network device sends its determined uplink positioning reference signal configuration to the LMF network element via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message. The uplink positioning reference signal configuration sent by the network device to the terminal device is carried in an RRC message. This RRC message includes at least one of an RRC release message, an RRC reconfiguration message, and an RRC setup message.

[0140] It should be noted that steps 604 and 606 above are parallel schemes. That is, when the terminal device requests the LMF network element to configure the uplink positioning reference signal, it will receive the uplink positioning reference signal configuration sent to it by the LMF network element, or receive the uplink positioning reference signal configuration sent to it by the network device.

[0141] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the LMF network element, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the terminal device's request when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the time delay in configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0142] Figure 7 A flowchart illustrating a method for configuring an uplink positioning reference signal according to an embodiment of this application is shown. This method can be applied to... Figure 1 In the access network device shown, the method includes:

[0143] Step 702: Receive the request message sent by the terminal device.

[0144] This request message is used to request the network device to configure an uplink positioning reference signal for the terminal device. For example, configuring an uplink positioning reference signal for the terminal device refers to configuring the terminal device to send an uplink positioning reference signal. This uplink positioning reference signal configuration is used by the terminal device to send the uplink positioning reference signal, and for example, the uplink positioning reference signal configuration includes the time-frequency resources used by the terminal device to send the uplink positioning reference signal.

[0145] Optionally, the request message sent by the terminal device to the network device is carried in the RRC resume request message.

[0146] Step 704: Determine the uplink positioning reference signal configuration.

[0147] The uplink positioning reference signal configuration is determined by the network device in response to a request message from the terminal device. When the terminal device sends a request message to the network device, the network device will respond to the request message and determine the uplink positioning reference signal configuration for the terminal device. Optionally, the network device belongs to the serving cell of the terminal device.

[0148] Step 706: Send uplink positioning reference signal configuration to the terminal device.

[0149] After determining the uplink positioning reference signal configuration for the terminal device, the network device sends the determined uplink positioning reference signal configuration to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, the network device may also send its determined uplink positioning reference signal configuration to the LMF network element.

[0150] Optionally, the uplink positioning reference signal configuration sent by the network device to the terminal device is carried in the RRC message. This RRC message includes at least one of an RRC release message, an RRC reconfiguration message, and an RRC setup message. The uplink positioning reference signal configuration sent by the network device to the LMF network element is carried in the NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0151] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the network device, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the request of the terminal device when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the latency of configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0152] Figure 8 A flowchart illustrating a method for configuring an uplink positioning reference signal according to an embodiment of this application is shown. This method can be applied to... Figure 1 In the access network device shown, the method includes:

[0153] Step 802: Receive the request from the LMF network element.

[0154] The request is used to request the network device to configure an uplink positioning reference signal for the terminal device. This request is sent by the LMF (Local Management Function) upon receiving a request message from the terminal device. The request message is used to request the LMF network element to configure the uplink positioning reference signal for the terminal device. For example, configuring the uplink positioning reference signal for the terminal device refers to sending an uplink positioning reference signal configuration to the terminal device. This uplink positioning reference signal configuration is used by the terminal device to send the uplink positioning reference signal; for example, the uplink positioning reference signal configuration includes the time-frequency resources used by the terminal device to send the uplink positioning reference signal.

[0155] Optionally, the LMF network element requests the network device to configure the uplink positioning reference signal to the terminal device via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0156] Step 804: Determine the uplink positioning reference signal configuration.

[0157] The uplink positioning reference signal configuration is determined by the network device in response to a request from an LMF (Local Multi-Function) network element. When an LMF network element requests the network device to configure the uplink positioning reference signal for the terminal device, the network device responds to the request and determines the uplink positioning reference signal configuration for the terminal device. Optionally, this network device belongs to the serving cell of the terminal device.

[0158] Step 806: Send uplink positioning reference signal configuration to LMF network element.

[0159] After determining the uplink positioning reference signal configuration for the terminal device, the network device sends the determined uplink positioning reference signal configuration to the LMF network element. Then, the LMF network element sends the uplink positioning reference signal configuration determined by the network device to the terminal device, thereby realizing the configuration of the uplink positioning reference signal for the terminal device.

[0160] Optionally, the network device sends its determined uplink positioning reference signal configuration to the LMF network element via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message. The uplink positioning reference signal configuration sent by the LMF network element to the terminal device is carried in an LPP message.

[0161] Step 808: Send uplink positioning reference signal configuration to the terminal device.

[0162] After determining the uplink positioning reference signal configuration for the terminal device, the network device will directly send the determined uplink positioning reference signal configuration to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, the network device may also send the determined uplink positioning reference signal configuration to the LMF network element.

[0163] Optionally, the uplink positioning reference signal configuration sent by the network device to the terminal device is carried in an RRC message. This RRC message includes at least one of an RRC release message, an RRC reconfiguration message, and an RRC setup message. The network device sends its determined uplink positioning reference signal configuration to the LMF network element via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0164] It should be noted that steps 806 and 808 above are parallel schemes. That is, when the network device configures the uplink positioning reference signal for the terminal device according to the request of the LMF network element, it will send the determined uplink positioning reference signal configuration to the LMF network element, and the LMF network element will then send the uplink positioning reference signal configuration to the terminal device. Alternatively, the network device may directly send the determined uplink positioning reference signal configuration to the terminal device.

[0165] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the LMF network element, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the terminal device's request when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the time delay in configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0166] Figure 9 A flowchart illustrating a method for configuring an uplink positioning reference signal according to an embodiment of this application is shown. This method can be applied to... Figure 1 In the terminal device shown, the method includes:

[0167] Step 902: Receive the request message sent by the terminal device.

[0168] This request message is used to request the LMF network element to configure an uplink positioning reference signal for the terminal device. For example, configuring an uplink positioning reference signal for the terminal device refers to configuring the uplink positioning reference signal to be sent by the terminal device. This uplink positioning reference signal configuration is used by the terminal device to send the uplink positioning reference signal, and for example, the uplink positioning reference signal configuration includes the time-frequency resources used by the terminal device to send the uplink positioning reference signal.

[0169] Optionally, the request message also carries the reason why the terminal device requests the uplink positioning reference signal. The reason why the terminal device requests the uplink positioning reference signal includes at least one of the following:

[0170] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0171] • The terminal device experienced a cell reselection.

[0172] Optionally, the LMF network element receives request messages sent by the terminal device in at least the following two ways:

[0173] Regarding the situation where request messages from terminal devices are received via network devices:

[0174] The LMF network element, through the network device, can receive request messages sent by the terminal device. The LMF network element receives the request message sent by the terminal device based on the RRC recovery request message, which is then transmitted by the network device to the LMF network element. During this process, the LMF network element receives the request message from the terminal device, based on the RRC recovery request message, sent by the network device. The terminal device's request message is sent to the network device based on the RRC recovery request message; the RRC recovery request message carries UL information transfer, and the UL information transfer carries the request message. After receiving the above information from the terminal device, the network device sends the UL information transfer to the LMF network element. Optionally, the UL information transfer refers to the uplink NAS transport. Optionally, the network device transmitting the terminal device's request message may or may not belong to the terminal device's serving cell.

[0175] For cases where request messages from terminal devices are received directly via LPP:

[0176] The LMF network element can directly receive request messages sent by the terminal device. In this case, the request message sent by the terminal device to the LMF network element is carried in the LPP message.

[0177] It should be noted that the terminal device can also send request messages to the LMF network element in other ways. The above implementation methods are only used as examples and are not intended to limit the solutions provided in the embodiments of this application.

[0178] Step 904: Request the network device to configure the uplink positioning reference signal for the terminal device.

[0179] When a terminal device sends a request message to an LMF network element, the LMF network element will respond to the request message, requesting the network device to configure an uplink positioning reference signal for the terminal device. Optionally, this network device belongs to the terminal device's serving cell.

[0180] Optionally, the LMF network element requests the network device to configure the uplink positioning reference signal to the terminal device via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0181] Step 906: Receive uplink positioning reference signal configuration sent by network device.

[0182] The uplink positioning reference signal configuration is determined by the network device in response to a request from an LMF network element. When an LMF network element requests the network device to configure the uplink positioning reference signal for the terminal device, the network device will respond to the request and determine the uplink positioning reference signal configuration for the terminal device.

[0183] Optionally, the network device sends its determined uplink positioning reference signal configuration to the LMF network element via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message. The uplink positioning reference signal configuration sent by the LMF network element to the terminal device is carried in an LPP message.

[0184] Step 908: Send uplink positioning reference signal configuration to the terminal device.

[0185] After receiving the uplink positioning reference signal configuration determined by the network device, the LMF network element sends the uplink positioning reference signal configuration determined by the network device to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, the uplink positioning reference signal configuration sent by the LMF network element to the terminal device is carried in the LPP message.

[0186] Optionally, after receiving a request from the LMF network element and determining the uplink positioning reference signal configuration for the terminal device, the network device can also directly send the determined uplink positioning reference signal configuration to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, in this case, the network device will also send its determined uplink positioning reference signal configuration to the LMF network element.

[0187] Optionally, the uplink positioning reference signal configuration sent by the network device to the terminal device is carried in the RRC message. This RRC message includes at least one of the following: an RRC release message, an RRC reconfiguration message, and an RRC setup message.

[0188] Optionally, when a terminal device requests the network device to configure an uplink positioning reference signal, the LMF network element will receive the uplink positioning reference signal configuration sent by the network device. This uplink positioning reference signal configuration is determined by the network device in response to the request message sent by the terminal device.

[0189] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the LMF network element, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the terminal device's request when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the time delay in configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0190] The method provided in this application allows a terminal device to request configuration of an uplink positioning reference signal from a network device and / or an LMF (Local Modem) element. When a terminal device requests configuration of an uplink positioning reference signal from an LMF element, the LMF element sends the uplink positioning reference signal configuration to the terminal device, or the network device sends the uplink positioning reference signal configuration to the terminal device. The above solution is described below through three embodiments:

[0191] For situations where a terminal device requests configuration of an uplink positioning reference signal from a network device:

[0192] Figure 10 A flowchart illustrating a method for configuring an uplink positioning reference signal according to an embodiment of this application is shown. This method can be applied to... Figure 1 In the system shown, the method includes:

[0193] Step 1002: The terminal device sends a request message to the network device.

[0194] This request message is used to request the network device to configure an uplink positioning reference signal for the terminal device. Optionally, the request message also carries the reason why the terminal device requests the uplink positioning reference signal. The reason why the terminal device requests the uplink positioning reference signal includes at least one of the following:

[0195] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0196] • The terminal device experienced a cell reselection.

[0197] Optionally, the terminal device will send the above request message to the network device if at least one of the following conditions is met:

[0198] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0199] • The uplink positioning reference signal stored in the terminal device has been activated;

[0200] • The uplink positioning reference signal stored by the terminal device is a periodic uplink positioning reference signal.

[0201] For example, the above conditions include at least one of the following conditions:

[0202] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0203] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device has been activated;

[0204] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device is a periodic uplink positioning reference signal.

[0205] Optionally, the request message sent by the terminal device to the network device is carried in the RRC recovery request message.

[0206] Step 1004: The network device determines the uplink positioning reference signal configuration.

[0207] The uplink positioning reference signal configuration is determined by the network device in response to a request message from the terminal device. When the terminal device sends a request message to the network device, the network device will respond to the request message and determine the uplink positioning reference signal configuration for the terminal device. Optionally, the network device belongs to the serving cell of the terminal device.

[0208] Step 1006: The network device sends an uplink positioning reference signal configuration to the terminal device.

[0209] After determining the uplink positioning reference signal configuration for the terminal device, the network device sends the determined uplink positioning reference signal configuration to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, the network device may also send its determined uplink positioning reference signal configuration to the LMF network element.

[0210] Optionally, the uplink positioning reference signal configuration sent by the network device to the terminal device is carried in the RRC message. This RRC message includes at least one of an RRC release message, an RRC reconfiguration message, and an RRC setup message. The uplink positioning reference signal configuration sent by the network device to the LMF network element is carried in the NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0211] Step 1008: The network device sends an uplink positioning reference signal configuration to the LMF network element.

[0212] After determining the uplink positioning reference signal configuration for the terminal device, the network device will also send the determined uplink positioning reference signal configuration to the LMF network element. The LMF network element can know the uplink positioning reference signal configured for the terminal device based on the uplink positioning reference signal configuration sent by the network device.

[0213] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the network device, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the request of the terminal device when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the latency of configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0214] When a terminal device requests configuration of an uplink positioning reference signal from an LMF network element, the LMF network element sends the uplink positioning reference signal configuration information to the terminal device:

[0215] Figure 11 A flowchart illustrating a method for configuring an uplink positioning reference signal according to an embodiment of this application is shown. This method can be applied to... Figure 1 In the system shown, the method includes:

[0216] Step 1102: The terminal device sends a request message to the LMF network element.

[0217] This request message is used to request the LMF network element to configure an uplink positioning reference signal for the terminal device. Optionally, the request message also carries the reason why the terminal device requests the uplink positioning reference signal. The reason why the terminal device requests the uplink positioning reference signal includes at least one of the following:

[0218] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0219] • The terminal device experienced a cell reselection.

[0220] Optionally, the terminal device will send the above request message to the LMF network element if at least one of the following conditions is met:

[0221] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0222] • The uplink positioning reference signal stored in the terminal device has been activated;

[0223] • The uplink positioning reference signal stored by the terminal device is a periodic uplink positioning reference signal.

[0224] For example, the above conditions include at least one of the following conditions:

[0225] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0226] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device has been activated;

[0227] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device is a periodic uplink positioning reference signal.

[0228] Optionally, the terminal device sends a request message to the LMF network element in at least two of the following ways:

[0229] For cases where request messages are sent from network devices to LMF network elements:

[0230] The terminal device sends a request message to the LMF network element via the network device based on an RRC message, such as an RRC recovery request message. In other words, the network device transparently transmits the request message sent by the terminal device to the LMF network element. During this process, the terminal device sends a request message to the network device based on the RRC recovery request message. The RRC recovery request message carries UL information transfer, and the uplink transmission information carries the request message. After receiving the above information from the terminal device, the network device sends the uplink transmission information to the LMF network element. Optionally, the uplink transmission information refers to uplink NAS transport. Optionally, the network device that transparently transmits the terminal device's request message may or may not belong to the terminal device's serving cell.

[0231] For the case where request messages are sent directly to LMF network elements via LPP:

[0232] When a terminal device sends a request message directly to an LMF network element, the request message sent by the terminal device to the LMF network element is carried in an LPP message.

[0233] It should be noted that the terminal device can also send request messages to the LMF network element in other ways. The above implementation methods are only used as examples and are not intended to limit the solutions provided in the embodiments of this application.

[0234] Step 1104: The LMF network element requests the network device to configure the uplink positioning reference signal for the terminal device.

[0235] When a terminal device sends a request message to an LMF network element, the LMF network element will respond to the request message, requesting the network device to configure an uplink positioning reference signal for the terminal device. Optionally, this network device belongs to the terminal device's serving cell.

[0236] Optionally, the LMF network element requests the network device to configure the uplink positioning reference signal to the terminal device via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0237] Step 1106: The network device determines the uplink positioning reference signal configuration.

[0238] The uplink positioning reference signal configuration is determined by the network device in response to a request from an LMF network element. When an LMF network element requests the network device to configure the uplink positioning reference signal for the terminal device, the network device will respond to the request and determine the uplink positioning reference signal configuration for the terminal device.

[0239] Step 1108: The network device sends an uplink positioning reference signal configuration to the LMF network element.

[0240] After determining the uplink positioning reference signal configuration for the terminal device, the network device sends the determined uplink positioning reference signal configuration to the LMF network element. Optionally, the network device sends the determined uplink positioning reference signal configuration to the LMF network element via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0241] Step 1110: The LMF network element sends an uplink positioning reference signal configuration to the terminal device.

[0242] After receiving the uplink positioning reference signal configuration determined by the network device, the LMF network element sends the uplink positioning reference signal configuration determined by the network device to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device. Optionally, the uplink positioning reference signal configuration sent by the LMF network element to the terminal device is carried in the LPP message.

[0243] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the LMF network element, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the terminal device's request when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the time delay in configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0244] When a terminal device requests configuration of an uplink positioning reference signal from an LMF network element, the network device sends the uplink positioning reference signal configuration information to the terminal device:

[0245] Figure 12 A flowchart illustrating a method for configuring an uplink positioning reference signal according to an embodiment of this application is shown. This method can be applied to... Figure 1 In the system shown, the method includes:

[0246] Step 1202: The terminal device sends a request message to the LMF network element.

[0247] This request message is used to request the LMF network element to configure an uplink positioning reference signal for the terminal device. Optionally, the request message also carries the reason why the terminal device requests the uplink positioning reference signal. The reason why the terminal device requests the uplink positioning reference signal includes at least one of the following:

[0248] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0249] • The terminal device experienced a cell reselection.

[0250] Optionally, the terminal device will send the above request message to the LMF network element if at least one of the following conditions is met:

[0251] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0252] • The uplink positioning reference signal stored in the terminal device has been activated;

[0253] • The uplink positioning reference signal stored by the terminal device is a periodic uplink positioning reference signal.

[0254] For example, the above conditions include at least one of the following conditions:

[0255] • The uplink positioning reference signal stored in the terminal device has become invalid;

[0256] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device has been activated;

[0257] • The uplink positioning reference signal stored in the terminal device has become invalid, and the uplink positioning reference signal stored in the terminal device is a periodic uplink positioning reference signal.

[0258] Optionally, the terminal device sends a request message to the LMF network element in at least two of the following ways:

[0259] For cases where request messages are sent from network devices to LMF network elements:

[0260] The terminal device sends a request message to the LMF network element via the network device based on an RRC message, such as an RRC recovery request message. In other words, the network device transparently transmits the request message sent by the terminal device to the LMF network element. During this process, the terminal device sends a request message to the network device based on the RRC recovery request message. The RRC recovery request message carries UL information transfer, and the uplink transmission information carries the request message. After receiving the above information from the terminal device, the network device sends the uplink transmission information to the LMF network element. Optionally, the uplink transmission information refers to uplink NAS transport. Optionally, the network device that transparently transmits the terminal device's request message may or may not belong to the terminal device's serving cell.

[0261] For the case where request messages are sent directly to LMF network elements via LPP:

[0262] When a terminal device sends a request message directly to an LMF network element, the request message sent by the terminal device to the LMF network element is carried in an LPP message.

[0263] It should be noted that the terminal device can also send request messages to the LMF network element in other ways. The above implementation methods are only used as examples and are not intended to limit the solutions provided in the embodiments of this application.

[0264] Step 1204: The LMF network element requests the network device to configure the uplink positioning reference signal for the terminal device.

[0265] When a terminal device sends a request message to an LMF network element, the LMF network element will respond to the request message, requesting the network device to configure an uplink positioning reference signal for the terminal device. Optionally, this network device belongs to the terminal device's serving cell.

[0266] Optionally, the LMF network element requests the network device to configure the uplink positioning reference signal to the terminal device via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0267] Step 1206: The network device determines the uplink positioning reference signal configuration.

[0268] The uplink positioning reference signal configuration is determined by the network device in response to a request from an LMF network element. When an LMF network element requests the network device to configure the uplink positioning reference signal for the terminal device, the network device will respond to the request and determine the uplink positioning reference signal configuration for the terminal device.

[0269] Step 1208: The network device sends an uplink positioning reference signal configuration to the terminal device.

[0270] After determining the uplink positioning reference signal configuration for the terminal device, the network device will directly send the determined uplink positioning reference signal configuration to the terminal device, thereby configuring the uplink positioning reference signal for the terminal device.

[0271] Optionally, the uplink positioning reference signal configuration sent by the network device to the terminal device is carried in an RRC message. This RRC message includes at least one of an RRC release message, an RRC reconfiguration message, and an RRC setup message. The network device sends its determined uplink positioning reference signal configuration to the LMF network element via an NRPPa message. This NRPPa message includes at least one of a UE association NRPPa message and a non-UE association NRPPa message.

[0272] Step 1210: The network device sends an uplink positioning reference signal configuration to the LMF network element.

[0273] After determining the uplink positioning reference signal configuration for the terminal device, the network device will also send the determined uplink positioning reference signal configuration to the LMF network element. The LMF network element can know the uplink positioning reference signal configured for the terminal device based on the uplink positioning reference signal configuration sent by the network device.

[0274] In summary, the method provided in this embodiment, by having the terminal device actively request the configuration of the uplink positioning reference signal from the LMF network element, enables the configuration of the uplink positioning reference signal for the terminal device in real time according to the terminal device's request when the terminal device releases the saved uplink positioning reference signal configuration. This reduces the time delay in configuring the uplink positioning reference signal for the terminal device, thereby reducing positioning latency and improving the flexibility of configuring the uplink positioning reference signal.

[0275] It should be noted that the order of the method steps provided in the embodiments of this application can be appropriately adjusted, and the steps can also be added or removed as appropriate. Any method variations that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the protection scope of this application, and therefore will not be elaborated further.
