[0037] The application scenarios of this application will be described below:

[0038] Figure 1 A block diagram of a communication system provided in an exemplary embodiment of this application is shown. The communication system may include a terminal 10 and a network device 20.

[0039] The number of terminals 10 is typically multiple, and one or more terminals 10 can be distributed within the cell managed by each network device 20. Terminals 10 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile station (MS), etc. For ease of description, in this embodiment, the devices mentioned above are collectively referred to as terminals.

[0040] Network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal 10. For ease of description, in this embodiment, the device providing wireless communication functionality to terminal 10 is collectively referred to as a network device. Network device 20 and terminal 10 can establish a connection via an air interface, thereby communicating through this connection, including signaling and data exchange. There can be multiple network devices 20, and two adjacent network devices 20 can communicate via wired or wireless means. Terminal 10 can switch between different network devices 20, that is, establish connections with different network devices 20.

[0041] The 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 network equipment functions may differ; for example, in a 5G NR (New Radio) system, it is called gNodeB or gNB. As communication technologies evolve, the name "network device" may change.

[0042] Figure 2 The flowchart illustrates an exemplary embodiment of the information configuration method provided in this application, which can be applied, for example, to... Figure 1 In the terminal and network device shown, the method includes at least some of the following:

[0043] Step 201: The network device sends configuration information to the terminal. The configuration information includes at least one BWP information. Each BWP information is associated with at least one area identifier. The at least one BWP information is used by the terminal to send uplink positioning reference signals when the terminal is in RRC idle state and / or RRC inactive state.

[0044] Step 202: The terminal receives configuration information sent by the network device. The configuration information includes at least one BWP information. Each BWP information is associated with at least one area identifier. The at least one BWP information is used by the terminal to send uplink positioning reference signals when the terminal is in RRC idle state and / or RRC inactive state.

[0045] In this embodiment, the terminal itself exists in an RRC idle state, an RRC inactive state, and an RRC connected state. When the terminal is in an RRC idle state or an RRC inactive state, if the terminal needs to send an uplink positioning reference signal to the network device, the network device needs to configure BWP information for the terminal first, and then send the uplink positioning reference signal based on the BWP information.

[0046] In this process, the network device sends configuration information to the terminal, which allows the terminal to configure at least one BWP (Browser Window) information. Each BWP information is associated with a region identifier, which indicates the region corresponding to the BWP information. The terminal then determines the BWP information configured by the network device and the region corresponding to the BWP information.

[0047] In some embodiments, the area identifier indicates at least one cell, and the area identifier is the identifier corresponding to the BWP information. That is, if the terminal is in at least one cell indicated by the area identifier, the BWP information corresponding to the area identifier is valid, and if the terminal is not in at least one cell indicated by the area identifier, the BWP information corresponding to the area identifier is invalid.

[0048] For example, the area identifier associated with BWP information indicates cell 1 and cell 2. If the terminal is located in cell 1, cell 1 is associated with BWP information, and the BWP information is effective and the terminal can use the BWP information. However, if the terminal is located in cell 3, which is outside of cell 1 and cell 2, then cell 3 is not associated with BWP information, the BWP information is invalid, and the terminal cannot use the BWP information.

[0049] In some embodiments, after the terminal sends an uplink positioning reference signal to the network device, the network device can locate the terminal based on the received uplink positioning reference signal.

[0050] In some embodiments, the BWP information includes at least one of the following:

[0051] (1) SCS (Sub Carrier Space).

[0052] The subcarrier spacing refers to the interval between two adjacent subcarriers, for example, the subcarrier spacing is 15KHz, 30KHz, or other values.

[0053] (2) CP (Cyclic Prefix).

[0054] The cyclic prefix is ​​a loop structure formed by copying a segment of data after a data symbol to the beginning of that symbol. This ensures that OFDM (Orthogonal Frequency Division Multiplexing) signals with time delays always have an integer multiple of the period within the FFT (Fast Fourier Transform) integration period.

[0055] (3) Frequency domain location of BWP.

[0056] The frequency domain position indicates the location of the BWP in the frequency domain.

[0057] (4) BWP bandwidth.

[0058] The bandwidth of the BWP indicates the frequency range occupied by the BWP in the frequency domain.

[0059] In some embodiments, the configuration information is an RRC release message, or the configuration information is an RRC reconfiguration message.

[0060] It should be noted that the steps performed by the network device can form a separate embodiment, and the steps performed by the terminal can also form a separate embodiment; this application does not limit this.

[0061] In the solution provided by this application embodiment, the terminal receives at least one BWP information, and at least one BWP information is associated with an area identifier. The BWP information is used by the terminal to send uplink positioning reference signals in the RRC idle state and / or inactive state. That is to say, after the terminal moves to the area indicated by the area identifier, the terminal can still send uplink positioning reference signals based on the configured BWP information, so as to facilitate the network device to locate the terminal, expand the way to locate the terminal, and ensure the stability of the terminal positioning.

[0062] This application also provides a configuration method in which at least one BWP information is obtained by a network device from an LMF or Xn interface, wherein the BWP is used by the terminal UE to send an uplink positioning reference signal.

[0063] In some embodiments, at least one BWP information is obtained by the network device from the LMF (Location Management Function) via NRPPa (NR Positioning Protocol A), or at least one BWP information is obtained by the network device via the Xn (a communication interface) interface.

[0064] For example, obtaining BWP information from LMF refers to the BWP information of neighboring cells used to send the uplink positioning reference signal, which the network device obtains from LMF via NRPPa.

[0065] In this embodiment of the application, the LMF is a network element in the core network. The LMF can obtain BWP information used to send uplink positioning reference signals in neighboring cells. The network device communicates with the LMF through NRPPa. Therefore, the network device can obtain the BWP information used to send uplink positioning reference signals from the LMF through NRPPa.

[0066] The following section explains how network devices obtain BWP information from LMF network elements.

[0067] Optionally, the LMF network element sends a BWP request message to the neighboring cell. This BWP request message is used to obtain the neighboring cell's BWP information. Upon receiving the BWP request message from the LMF network element, the neighboring cell responds by sending its own BWP information to the LMF. After receiving the BWP information from the neighboring cell, the LMF carries the neighboring cell's BWP information in an NRPPa message and sends the NRPPa message to the network device. This BWP information includes the neighboring cell's cell identifier.

[0068] Optionally, the network device sends a BWP request message to the LMF network element. Upon receiving the BWP request message, the LMF network element responds by sending a BWP request message to the neighboring cell. This BWP request message is used to obtain the neighboring cell's BWP information. The neighboring cell receives the BWP request message from the LMF network element and responds by sending its own BWP information to the LMF. After receiving the BWP information from the neighboring cell, the LMF carries the neighboring cell's BWP information in an NRPPa message and sends an NRPPa message to the network device. This BWP information includes the neighboring cell's cell identifier.

[0069] Furthermore, obtaining BWP information from the Xn interface refers to the network device acquiring BWP information from neighboring cells used to transmit the uplink positioning reference signal via the Xn interface. In other words, the network device can also obtain BWP information from other network devices, and since network devices communicate with each other via the Xn interface, the network device can obtain BWP information for transmitting the uplink positioning reference signal from network devices in neighboring cells through the Xn interface.

[0070] The following section explains how network devices obtain BWP information from other network devices.

[0071] In this scenario, the network equipment refers to the network equipment of the serving cell, while the other network equipment refers to the network equipment of neighboring cells. The serving cell sends a BWP request message to the neighboring cells through the Xn interface. Upon receiving the BWP request message, the neighboring cell responds by returning BWP information to the serving cell through the Xn interface. This BWP information includes the cell identifier of the neighboring cell.

[0072] It should be noted that, in the embodiments of this application, the serving cell is the cell for which BWP information is configured for the terminal, and the neighboring cell is the terminal's neighboring cell.

[0073] exist Figure 2 Based on the illustrated embodiment, the association between BWP information and area identifier includes various relationships, each of which is described below.

[0074] The first method: Each region identifier is associated with a BWP.

[0075] There is a one-to-one correspondence between the region identifier and the BWP, meaning that one region identifier is associated with one BWP. This can also be understood as the BWP being valid only within the region indicated by the associated region identifier.

[0076] For example, BWP1 is associated with region identifier 1. BWP2 is associated with region identifier 2.

[0077] The second scenario: There exists a BWP that is associated with multiple area identifiers.

[0078] One BWP is associated with multiple area identifiers, meaning that each area indicated by multiple area identifiers corresponds to one BWP, and the BWP is valid within the areas indicated by the multiple area identifiers.

[0079] For example, BWP1 is associated with region identifier 1 and region identifier 2. BWP2 is associated with region identifier 3, region identifier 4 and region identifier 5. BWP3 is associated with region identifier 6 and region identifier 7.

[0080] The third type: There are multiple BWPs, and each BWP is associated with at least one area identifier.

[0081] In this case, at least one area identifier is associated with multiple BWPs, meaning that multiple BWPs are valid within the area indicated by the area identifier, and the terminal can use any one of the multiple BWPs within the area indicated by the area identifier.

[0082] For example, BWP1 and BWP2 are associated with area identifier 1. BWP3, BWP4, and BWP5 are associated with area identifier 2.

[0083] In the solution provided in this application embodiment, the BWP included in the configuration information has multiple associations with the region identifier, that is, it includes multiple ways to configure the BWP for the terminal. While ensuring that the terminal is configured with the BWP and the associated region identifier, the diversity of the BWP configuration methods is improved.

[0084] It should be noted that this embodiment uses a region identifier as an example for illustration. In another embodiment, the region identifier can be represented by any of the following identifiers:

[0085] The first type: The area is marked as a community marker.

[0086] In this embodiment of the application, the cell identifier indicates a cell, that is, the area identifier indicates a cell, and the BWP information is associated with the cell identifier.

[0087] In some embodiments, the cell identifier may also be a global cell identifier.

[0088] For example, the cell identifier is represented by CGI (Cell Global ID).

[0089] Below, taking the area identifier as the cell identifier as an example, the association relationship between BWP information and area identifier will be explained separately. That is, for each relationship between BWP information and area identifier in the above embodiments, the area identifier can be replaced with the cell identifier:

[0090] (1) Each region identifier is associated with a BWP.

[0091] There is a one-to-one correspondence between cell identifiers and BWPs, meaning that one cell identifier is associated with one BWP. This can also be understood as the BWP being valid only within the cell indicated by the associated cell identifier.

[0092] For example, BWP1 is associated with cell identifier 1. BWP2 is associated with cell identifier 2.

[0093] (2) There exists a BWP that is associated with multiple cell identifiers.

[0094] One BWP is associated with multiple cell identifiers, meaning that each cell indicated by multiple cell identifiers corresponds to one BWP, and the BWP is valid within the cells indicated by the multiple cell identifiers.

[0095] For example, BWP1 is associated with cell identifier 1 and cell identifier 2. BWP2 is associated with cell identifier 3, cell identifier 4 and cell identifier 5. BWP3 is associated with cell identifier 6 and cell identifier 7.

[0096] (3) There are multiple BWPs, and each BWP is associated with at least one cell identifier.

[0097] In this case, at least one cell identifier is associated with multiple BWPs, meaning that within the cell indicated by the cell identifier, multiple BWPs are valid, and the terminal can use any one of the multiple BWPs within the cell indicated by the cell identifier.

[0098] For example, BWP1 and BWP2 are associated with cell identifier 1. BWP3, BWP4, and BWP5 are associated with cell identifier 2.

[0099] The second type: The area is identified as a RAN (Radio Access Network) area identifier.

[0100] The RAN area identifier indicates a RAN area, and the RAN area includes at least one cell. That is, the RAN area indicated by the RAN area identifier includes one or more cells, and the one or more cells share the BWP information associated with the RAN area identifier.

[0101] In some embodiments, the RAN area identifier is represented by the RAN area code.

[0102] Below, taking the RAN region identifier as an example, the association relationship between BWP information and region identifier will be explained separately. That is, for each relationship between BWP information and region identifier in the above embodiments, the region identifier can be replaced with the RAN region identifier:

[0103] (1) Each RAN area identifier is associated with a BWP.

[0104] There is a one-to-one correspondence between RAN area identifiers and BWPs, meaning that one RAN area identifier is associated with one BWP. This can also be understood as the BWP being valid within the RAN area indicated by the associated RAN area identifier.

[0105] For example, BWP1 is associated with RAN area identifier 1. BWP2 is associated with RAN area identifier 2.

[0106] (2) There exists a BWP that is associated with multiple RAN area identifiers.

[0107] One BWP is associated with multiple RAN area identifiers. In other words, the RAN areas indicated by multiple RAN area identifiers correspond to one BWP, and the BWP is valid within the RAN areas indicated by the multiple RAN area identifiers.

[0108] For example, BWP1 is associated with RAN area identifier 1 and RAN area identifier 2. BWP2 is associated with RAN area identifier 3, RAN area identifier 4 and RAN area identifier 5. BWP3 is associated with RAN area identifier 6 and RAN area identifier 7.

[0109] (3) There are multiple BWPs, and each BWP is associated with at least one RAN area identifier.

[0110] In this case, at least one RAN area identifier is associated with multiple BWPs, meaning that multiple BWPs are valid within the RAN area indicated by the RAN area identifier, and the terminal can use any one of the multiple BWPs within the RAN area indicated by the RAN area identifier.

[0111] For example, BWP1 and BWP2 are associated with RAN area identifier 1. BWP3, BWP4, and BWP information 5 are associated with RAN area identifier 2.

[0112] The third type: This area is identified as a system message area identifier.

[0113] The system message area identifier indicates a system message area, and the system message area includes at least one cell. That is, the system message area indicated by the system message area identifier includes one or more cells, and one or more cells share the BWP information associated with the system message area identifier.

[0114] In some embodiments, the system message area identifier is represented by systemInformationAreaID.

[0115] Below, taking the system message region identifier as an example, the association relationship between BWP information and region identifier will be explained separately. That is, for each relationship between BWP information and region identifier in the above embodiments, the region identifier can be replaced with the system message region identifier:

[0116] (1) Each system message area identifier is associated with a BWP.

[0117] There is a one-to-one correspondence between the system message area identifier and the BWP, meaning that one system message area identifier is associated with one BWP. This can also be understood as the BWP being valid only within the system message area indicated by the associated system message area identifier.

[0118] For example, BWP1 is associated with system message area identifier 1. BWP2 is associated with system message area identifier 2.

[0119] (2) There exists a BWP that is associated with multiple system message area identifiers.

[0120] One BWP is associated with multiple system message area identifiers. In other words, the system message areas indicated by multiple system message area identifiers correspond to one BWP, and the BWP is valid within the system message areas indicated by multiple system message area identifiers.

[0121] For example, BWP1 is associated with system message area identifier 1 and system message area identifier 2. BWP2 is associated with system message area identifier 3, system message area identifier 4, and system message area identifier 5. BWP3 is associated with system message area identifier 6 and system message area identifier 7.

[0122] (3) There are multiple BWPs, and each BWP is associated with at least one system message area identifier.

[0123] In this system message area identifier, at least one system message area identifier is associated with multiple BWPs. That is, within the system message area indicated by the system message area identifier, multiple BWPs are valid, and the terminal can use any one of the multiple BWPs within the system message area indicated by the system message area identifier.

[0124] For example, BWP1 and BWP2 are associated with system message area identifier 1. BWP3, BWP4, and BWP5 are associated with system message area identifier 2.

[0125] It should be noted that the embodiments in this application are illustrated using any one of the following as an example: a cell identifier, a RAN region identifier, or a system message region identifier. In another embodiment, the region identifier can also be a newly defined identifier, without needing to use the identifier in the above embodiments to indicate the region identifier.

[0126] In the solution provided in this application embodiment, the area identifier can be represented by different types of identifiers. That is, different types of identifiers are used to indicate the area corresponding to the BWP information, which expands the representation of the area identifier and ensures the accuracy of indicating the area associated with the BWP information.

[0127] exist Figure 2 Based on the illustrated embodiment, after the network device configures BWP information for the terminal, the terminal can send an uplink positioning reference signal based on the configured BWP information. See also... Figure 3 The method includes:

[0128] Step 301: When the terminal is in the RRC idle state and / or RRC inactive state, it sends an uplink positioning reference signal to the network device based on at least one BWP information.

[0129] In this embodiment of the application, if the terminal is in an RRC idle state and / or an RRC inactive state, the terminal can send an uplink reference signal to the network device according to at least one BWP information configured by the network device.

[0130] In some embodiments, each of the at least one BWP information is associated with a region identifier, so the terminal can send an uplink reference signal to the network device based on the at least one BWP information and the at least one region identifier associated with each BWP information.

[0131] Wherein, the terminal is in an RRC idle state and / or an RRC inactive state, and sends an uplink positioning reference signal to the network device based on at least one BWP information, including any of the following schemes:

[0132] In some embodiments, the terminal is in an RRC idle state and / or an RRC inactive state, and the area where the terminal is located is associated with BWP information. An uplink positioning reference signal is sent according to the BWP information corresponding to the area identifier.

[0133] In this embodiment, if the terminal is in an RRC idle state and / or an RRC inactive state, and the area where the terminal is located is in the area indicated by the area identifier configured by the network device, then the BWP information associated with the area where the terminal is located is indicated, and then an uplink positioning reference signal is sent according to the BWP information corresponding to the area identifier to which the area where the terminal is located belongs.

[0134] Once the terminal determines the area identifier corresponding to the area it is located in, it can determine the BWP information associated with that area identifier, and then determine the BWP based on that BWP information. The terminal can then send an uplink positioning reference signal on the determined BWP.

[0135] For example, each BWP information configured by the network device is associated with an area identifier, and this area identifier is a cell identifier. The network device configures BWP information 1, BWP information 2, and BWP information 3 for the terminal. BWP information 1 is associated with cell identifier 1, which indicates cell 1. BWP information 2 is associated with cell identifier 2, which indicates cell 2. BWP information 3 is associated with cell identifier 3, which indicates cell 3. If the area where the terminal is located belongs to the area covered by cell 2, it means that cell identifier 2 corresponding to cell 2 is associated with BWP information 2. Then the terminal can send an uplink positioning reference signal to the network device according to BWP information 2.

[0136] For example, each BWP information configured by the network device is associated with multiple area identifiers, and these area identifiers are cell identifiers. The network device configures BWP information 1 and BWP information 2 for the terminal. BWP information 1 is associated with cell identifier 1 and cell identifier 2. Cell identifier 1 indicates cell 1, and cell identifier 2 indicates cell 2. BWP information 2 is associated with cell identifier 3, cell identifier 4, and cell identifier 5. Cell identifier 3 indicates cell 3, cell identifier 4 indicates cell 4, and cell identifier 5 indicates cell 5. If the area where the terminal is located belongs to the area covered by cell 2, it means that cell identifier 2 corresponding to cell 2 is associated with BWP information 2. Then the terminal can send an uplink positioning reference signal to the network device according to BWP information 2.

[0137] For example, each BWP information configured by the network device is associated with multiple area identifiers, and these area identifiers are RAN area identifiers. The network device configures BWP information 1 and BWP information 2 for the terminal. BWP information 1 is associated with RAN area identifier 1 and RAN area identifier 2. RAN area identifier 1 indicates cell 1 and cell 2, and RAN area identifier 2 indicates cell 3, cell 4 and cell 5. BWP information 2 is associated with RAN area identifier 3, RAN area identifier 4 and RAN area identifier 5. RAN area identifier 3 indicates cell 6 and cell 7, RAN area identifier 4 indicates cell 8, cell 9 and cell 10, and RAN area identifier 5 indicates cell 11 and cell 12. If the area where the terminal is located belongs to the area covered by cell 7, it means that RAN area identifier 3 corresponding to cell 7 is associated with BWP information 2. Then the terminal can send an uplink positioning reference signal to the network device according to BWP information 2.

[0138] It should be noted that the embodiments in this application are used to illustrate the association relationship by way of example. This application is not limited to the above examples. The network device can also configure other association relationships for the terminal.

[0139] In other embodiments, the terminal is in an RRC idle state and / or an RRC inactive state, and the area where the terminal is located has no associated BWP information, and an uplink positioning reference signal is sent based on the initial BWP.

[0140] The initial BWP can be a BWP configured by the network device for the terminal through system message broadcast, or it can be a BWP agreed upon by the network device and the terminal through a protocol, or it can be a BWP configured in other ways. This application embodiment does not limit the specific BWP.

[0141] In this embodiment, if the terminal is in an RRC idle state and / or an RRC inactive state, and there is no associated BWP information in the area where the terminal is located, it means that the terminal cannot send uplink positioning reference signals using the BWP information configured by the network device. However, since the network device has provided the terminal with initial BWP information, the terminal can send uplink positioning reference signals based on the initial BWP.

[0142] Once the terminal determines that it is not located in the area corresponding to the area identifier configured on the network device, it can determine the initial BWP. The terminal can then send an uplink positioning reference signal on the determined initial BWP.

[0143] For example, each BWP information configured by the network device is associated with an area identifier, and this area identifier is a cell identifier. The network device configures BWP information 1, BWP information 2, and BWP information 3 for the terminal. BWP information 1 is associated with cell identifier 1, which indicates cell 1; BWP information 2 is associated with cell identifier 2, which indicates cell 2; and BWP information 3 is associated with cell identifier 3, which indicates cell 3. If the area where the terminal is located does not belong to the area covered by any of the cells 1, 2, and 3, it means that the area where the terminal is located is not associated with BWP information. In this case, the terminal can send an uplink positioning reference signal to the network device based on the initial BWP.

[0144] For example, each BWP information configured by the network device is associated with multiple area identifiers, and these area identifiers are cell identifiers. The network device configures BWP information 1 and BWP information 2 for the terminal. BWP information 1 is associated with cell identifier 1 and cell identifier 2. Cell identifier 1 indicates cell 1, and cell identifier 2 indicates cell 2. BWP information 2 is associated with cell identifier 3, cell identifier 4, and cell identifier 5. Cell identifier 3 indicates cell 3, cell identifier 4 indicates cell 4, and cell identifier 5 indicates cell 5. If the area where the terminal is located does not belong to the area covered by any of the cells 1, 2, 3, 4, and 5, it means that the area where the terminal is located is not associated with BWP information. In this case, the terminal can send an uplink positioning reference signal to the network device based on the initial BWP.

[0145] For example, each BWP information configured by the network device is associated with multiple area identifiers, and these area identifiers are RAN area identifiers. The network device configures BWP information 1 and BWP information 2 for the terminal. BWP information 1 is associated with RAN area identifier 1 and RAN area identifier 2. RAN area identifier 1 indicates cell 1 and cell 2, and RAN area identifier 2 indicates cell 3, cell 4 and cell 5. BWP information 2 is associated with RAN area identifier 3, RAN area identifier 4 and RAN area identifier 5. RAN area identifier 3 indicates cell 6 and cell 7, RAN area identifier 4 indicates cell 8, cell 9 and cell 10, and RAN area identifier 5 indicates cell 11 and cell 12. If the area where the terminal is located does not belong to the area covered by any of the cells 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12, it means that the area where the terminal is located is not associated with BWP information. In this case, the terminal can send an uplink positioning reference signal to the network device based on the initial BWP.

[0146] It should be noted that the embodiments in this application are used to illustrate the association relationship by way of example. This application is not limited to the above examples. The network device can also configure other association relationships for the terminal.

[0147] It should be noted that the embodiments in this application are illustrated using the example of sending an uplink positioning reference signal based on an initial BWP. In another embodiment, the terminal does not send an uplink positioning reference signal, but instead releases at least one BWP information configured by the network device.

[0148] Specifically, the terminal is in an RRC idle state and / or an RRC inactive state, and the area where the terminal is located has no associated BWP information, and at least one BWP information is released.

[0149] In this embodiment, if the terminal is in an RRC idle state and / or an RRC inactive state, and the area where the terminal is located has no associated BWP information, it means that the terminal cannot send uplink positioning reference signals using the BWP information configured by the network device. Therefore, the terminal will no longer send uplink positioning reference signals and will release at least one BWP information configured by the network device.

[0150] For example, each BWP information configured by the network device is associated with an area identifier, and this area identifier is a cell identifier. The network device configures BWP information 1, BWP information 2, and BWP information 3 for the terminal. BWP information 1 is associated with cell identifier 1, which indicates cell 1. BWP information 2 is associated with cell identifier 2, which indicates cell 2. BWP information 3 is associated with cell identifier 3, which indicates cell 3. If the area where the terminal is located does not belong to the area covered by any of the cells 1, 2, and 3, it means that the area where the terminal is located is not associated with BWP information. In this case, the terminal releases at least one BWP information configured by the network device.

[0151] For example, each BWP information configured by the network device is associated with multiple area identifiers, and these area identifiers are cell identifiers. The network device configures BWP information 1 and BWP information 2 for the terminal. BWP information 1 is associated with cell identifier 1 and cell identifier 2. Cell identifier 1 indicates cell 1, and cell identifier 2 indicates cell 2. BWP information 2 is associated with cell identifier 3, cell identifier 4, and cell identifier 5. Cell identifier 3 indicates cell 3, cell identifier 4 indicates cell 4, and cell identifier 5 indicates cell 5. If the area where the terminal is located does not belong to the area covered by any of the cells 1, 2, 3, 4, and 5, it means that the area where the terminal is located is not associated with BWP information. In this case, the terminal releases at least one BWP information configured by the network device.

[0152] For example, each BWP information configured by the network device is associated with multiple area identifiers, and these area identifiers are RAN area identifiers. The network device configures BWP information 1 and BWP information 2 for the terminal. BWP information 1 is associated with RAN area identifier 1 and RAN area identifier 2. RAN area identifier 1 indicates cell 1 and cell 2, and RAN area identifier 2 indicates cell 3, cell 4 and cell 5. BWP information 2 is associated with RAN area identifier 3, RAN area identifier 4 and RAN area identifier 5. RAN area identifier 3 indicates cell 6 and cell 7, RAN area identifier 4 indicates cell 8, cell 9 and cell 10, and RAN area identifier 5 indicates cell 11 and cell 12. If the area where the terminal is located does not belong to the area covered by any of the cells 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12, it means that the area where the terminal is located is not associated with BWP information. In this case, the terminal releases at least one BWP information configured by the network device.

[0153] It should be noted that the embodiments in this application are only illustrated by the example of the terminal releasing at least one BWP information configured by the network device. In another embodiment, the network device also configures an uplink positioning reference signal configuration for the terminal. If the terminal determines not to send an uplink positioning reference signal, the terminal will not only release at least one BWP information configured by the network device, but also release the configured uplink positioning reference signal configuration.

[0154] In some embodiments, if the terminal needs to determine whether the area it is located in is associated with BWP information, the terminal can determine whether the area it is located in is associated with BWP information based on the area identifier associated with each BWP information.

[0155] In this embodiment of the application, after the terminal receives at least one BWP information configured by the network device, it can determine the region associated with the BWP information based on the region identifier associated with each BWP information. The terminal can also determine its own region. Therefore, when the terminal determines that its own region is within the region indicated by the region identifier, it means that the region where the terminal is located is associated with BWP information. When the terminal determines that its own region is not within the region indicated by the region identifier, it means that the region where the terminal is located is not associated with BWP information.

[0156] Step 302: The network device receives an uplink positioning reference signal sent by the terminal based on at least one BWP information. The uplink positioning reference signal is sent by the terminal when it is in the RRC idle state and / or the RRC inactive state.

[0157] In this embodiment of the application, the network device configures at least one BWP information for the terminal, and the configured at least one BWP information is used for the terminal to send uplink positioning reference signals when it is in the RRC idle state and / or the RRC inactive state. Then, for the network device, the network device can receive the uplink positioning reference signals sent by the terminal based on at least one BWP information.

[0158] In the solution provided by this application embodiment, when the terminal is in the RRC idle state and / or the RRC inactive state, it sends an uplink positioning reference signal to the network device based on at least one BWP information. That is to say, after the terminal moves to the area indicated by the area identifier, the terminal can still send an uplink positioning reference signal based on the configured BWP information so that the network device can locate it. This expands the way the terminal is located and ensures the stability of the terminal positioning.

[0159] exist Figure 3 Based on the illustrated embodiment, after receiving the uplink positioning reference signal sent by the terminal, the network device also needs to perform positioning based on the uplink positioning reference signal, see [link to example]. Figure 4 The method includes:

[0160] Step 401: The network device locates the terminal based on the uplink positioning reference signal.

[0161] In this embodiment of the application, the network device configures BWP information for the terminal to send uplink positioning reference signals. After the terminal sends the uplink positioning reference signals, the network device can locate the terminal based on the received uplink positioning reference signals.

[0162] Step 402: The network device obtains the location information of the terminal.

[0163] In this embodiment of the application, after the network device locates the terminal, it can obtain the location of the terminal and thus determine the location information of the terminal.

[0164] In some embodiments, the network device locates the terminal using UL TDOA (Uplink Time Difference of Arrival) positioning technology.

[0165] In this embodiment of the application, the network device is configured with multiple TRPs, and each TRP can receive the uplink positioning reference signal sent by the terminal. For each TRP, the UL RTOA (Uplink Relative Time of Arrival) is determined based on the time when each TRP receives the uplink positioning reference signal and the reference time of the TRP. The network device determines the location information of the terminal based on the obtained UL RTOA and the location information of each TRP among the multiple TRPs.

[0166] Optionally, the network device is configured to synchronize the time between multiple TRPs to eliminate interference caused by time asynchrony between multiple TRPs when determining the terminal location information based on UL RTOA, thereby improving the accuracy of the determined terminal location information.

[0167] In the solution provided in this application embodiment, when the terminal is in the RRC idle state and / or the RRC inactive state, it sends an uplink positioning reference signal to the network device based on at least one BWP information. That is to say, after the terminal moves to the area indicated by the area identifier, the terminal can still send an uplink positioning reference signal based on the configured BWP information so that the network device can locate it and obtain the terminal's location information. This expands the way the terminal is located and ensures the stability of the terminal's location.

[0168] It should be noted that the above embodiments can be split into new embodiments, or combined with other embodiments to form new embodiments. This application does not limit the combination of embodiments.
