[0021] The following describes the application scenarios of this application. Figure 1 is a block diagram of a communication system provided by an exemplary embodiment of the present application, which may include a terminal 10 and a network device 20.

[0022] The number of terminals 10 is usually multiple, and one or more terminals 10 may be distributed within a cell managed by each network device 20. Terminals 10 may include handheld devices with wireless communication capabilities, in-vehicle devices, wearable devices, computing devices or other devices connected to wireless modems, and various forms of user equipment (UE), mobile stations (MS), etc. For ease of explanation, in the embodiments of this application, the above-mentioned devices are collectively referred to as terminals.

[0023] The network device 20 is located on an access network and is a device that provides wireless communication functionality for the terminal 10. For ease of explanation, in the embodiments of this application, the device that provides wireless communication functionality for the terminal 10 is collectively referred to as the network device. A connection can be established between the network device 20 and the terminal 10 via an air interface, and communication is performed through this connection, including signaling and data interaction. There may be multiple network devices 20, and two adjacent network devices 20 can communicate with each other by wired or wireless means. The terminal 10 can switch between different network devices 20, that is, establish connections with different network devices 20.

[0024] The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different radio access technologies, the name of the device with network device functionality may differ; for example, in a 5G NR (New Radio) system, it is called a gNodeB or gNB. As communication technology evolves, the term "network device" may change.

[0025] Figure 2 shows a flowchart of an information setting method provided by one exemplary embodiment of the present application. This method can be applied exemplary to the terminal and network device shown in Figure 1, and includes at least some of the following content: Step 201: The network device transmits configuration information to the terminal, which includes at least one BWP information, each BWP information in the at least one BWP information is associated with at least one area identifier, and the at least one BWP information is used by the terminal to transmit an uplink positioning reference signal in the RRC idle state and / or RRC inactive state.

[0026] Step 202: The terminal receives configuration information transmitted by the network device, the configuration information includes at least one BWP information, each BWP information in the at least one BWP information is associated with at least one area identifier, and the at least one BWP information is used by the terminal to transmit an uplink positioning reference signal in the RRC idle state and / or RRC inactive state.

[0027] In the embodiments of this application, the terminal itself has RRC idle state, RRC inactive state and RRC connected state, and when the terminal is in the RRC idle state or RRC inactive state, if the terminal needs to transmit an uplink positioning reference signal to the network device, the network device must first set BWP information for the terminal and then transmit an uplink positioning reference signal based on the BWP information.

[0028] The steps include: a network device sending configuration information to a terminal, which allows the terminal to be configured with at least one BWP information via said configuration information, each BWP information being associated with a region identifier which indicates the region corresponding to the BWP information, and the terminal further determining the BWP information and the region corresponding to the BWP information configured for the terminal by the network device.

[0029] In some embodiments, the region identifier indicates at least one cell, and the region identifier is an identifier corresponding to BWP information, meaning that if the terminal is located within at least one cell indicated by the region identifier, the BWP information corresponding to the region identifier is valid, and if the terminal is not located within at least one cell indicated by the region identifier, the BWP information corresponding to the region identifier is invalid.

[0030] For example, if the region identifier associated with BWP information points to cell 1 and cell 2, and the terminal is located within cell 1, then BWP information is associated with cell 1, the BWP information becomes valid, and the terminal can use it. If the terminal is located within cell 3, and cell 3 is located outside of cell 1 and cell 2, then BWP information is not associated with cell 3, the BWP information is invalid, and the terminal cannot use it.

[0031] In some embodiments, after the terminal transmits an uplink positioning reference signal to a network device, the network device can position the terminal based on the received uplink positioning reference signal.

[0032] In some embodiments, the BWP information includes at least one of the following: (1) SCS (Sub Carrier Space).

[0033] The subcarrier interval refers to the interval between two adjacent subcarriers, and for example, the subcarrier interval may be 15 kHz (kilohertz), 30 kHz, or another value.

[0034] (2) CP (Cyclic Prefix).

[0035] A cyclic prefix is ​​a cyclic structure formed by copying a row of data behind a data symbol to the front of that symbol. This ensures that a delayed OFDM (Orthogonal Frequency Division Multiplexing) signal always has a period that is an integer multiple within the FFT (Fast Fourier Transform) integration period.

[0036] (3) The frequency domain position of BWP.

[0037] The frequency domain position is the position of the indicated BWP within its frequency domain.

[0038] (4) BWP bandwidth.

[0039] The bandwidth of the BWP indicates the frequency range that the BWP occupies in the frequency domain.

[0040] In some embodiments, the configuration information is an RRC release message, or the configuration information is an RRC reconfiguration message.

[0041] Furthermore, steps performed by a network device can form a single embodiment on their own, and steps performed by a terminal can also form a single embodiment on their own; this application is not limited thereto.

[0042] In the solution provided by the embodiment of this application, a terminal receives at least one BWP information, the at least one BWP information is associated with a region identifier, and the BWP information transmits an uplink positioning reference signal when the terminal is in an RRC idle state and / or inactive state, i.e., after the terminal moves to a region indicated by the region identifier, the terminal can still transmit an uplink positioning reference signal based on the already set BWP information, which facilitates positioning by network devices, extends the method of positioning terminals, and ensures the stability of terminal positioning.

[0043] This application further provides a configuration method in which at least one BWP piece of information is obtained by a network device from an LMF or Xn interface, and the BWP is used by a terminal UE to transmit an uplink positioning reference signal.

[0044] In some embodiments, at least one BWP (Body Positioning Point) piece of information is acquired by a network device from an LMF (Location Management Function) via NRPPa (NR Positioning Protocol A), or at least one BWP piece of information is acquired by a network device via an Xn (Communication Interface) interface.

[0045] For example, obtaining BWP information from an LMF refers to BWP information that a network device uses to transmit the uplink positioning reference signal of an adjacent cell, which is obtained from the LMF via NRPPa.

[0046] In the embodiments of this application, the LMF is a network element in a core network, and the LMF can acquire BWP information for transmitting uplink positioning reference signals in adjacent cells, and communication between the network device and the LMF is via NRPPa, thereby allowing the network device to acquire BWP information for transmitting uplink positioning reference signals from the LMF via NRPPa.

[0047] The following explains how to obtain BWP information from LMF for network devices.

[0048] Selectively, an LMF network element sends BWP request information to an adjacent cell, and this BWP request information is used to obtain the adjacent cell's BWP information. The adjacent cell receives the BWP request information sent by the LMF network element and, in response to this BWP request information, sends its own BWP information to the LMF. After the LMF receives the BWP information sent by the adjacent cell, it carries the adjacent cell's BWP information in an NRPPa message and sends an NRPPa message to a network device. This BWP information includes the adjacent cell's cell identifier.

[0049] Selectively, a network device sends BWP request information to an LMF network element. After receiving this BWP request information, the LMF network element responds by sending BWP request information to an adjacent cell, which is then used to obtain the adjacent cell's BWP information. The adjacent cell receives the BWP request information sent by the LMF network element and responds by sending its own BWP information to the LMF. After the LMF receives the BWP information sent by the adjacent cell, it carries the adjacent cell's BWP information in an NRPPa message and sends an NRPPa message to the network device. This BWP information includes the adjacent cell's cell identifier.

[0050] Furthermore, obtaining BWP information from the Xn interface refers to BWP information that a network device obtains via the Xn interface for transmitting the uplink positioning reference signal of an adjacent cell. In other words, a network device can obtain BWP information via other network devices, and network devices can also communicate with each other via the Xn interface. Therefore, a network device can obtain BWP information from a network device in an adjacent cell via the Xn interface for transmitting the uplink positioning reference signal.

[0051] The following explains how network devices can obtain BWP information from other network devices.

[0052] If a network device is a network device of a serving cell and other network devices are network devices of an adjacent cell, the serving cell sends BWP request information to the adjacent cell via the Xn interface. After the adjacent cell receives the BWP request information, it responds to the BWP request information by returning BWP information to the serving cell via the Xn interface. This BWP information includes the cell identifier of the adjacent cell.

[0053] In this embodiment, the serving cell is a cell that sets BWP information for the terminal, and the adjacent cell is an adjacent cell for the terminal.

[0054] Based on the embodiment shown in Figure 2, the relationship between BWP information and region identifiers includes several types, and each relationship is explained below.

[0055] Type 1: Each domain identifier is associated with one BWP.

[0056] There is a one-to-one correspondence between region identifiers and BWPs; that is, one region identifier is associated with one BWP. It can also be understood that a BWP is valid only within the region indicated by the associated region identifier.

[0057] For example, BWP1 is associated with region identifier 1. BWP2 is associated with region identifier 2.

[0058] Type 2: One BWP exists, and that BWP is associated with multiple domain identifiers.

[0059] A single BWP is associated with multiple region identifiers; that is, each region indicated by multiple region identifiers corresponds to a single BWP, and that BWP is valid within the regions indicated by multiple region identifiers.

[0060] 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.

[0061] Third type: Multiple BWPs exist, and each BWP is associated with at least one region identifier.

[0062] At least one region identifier is associated with multiple BWPs, meaning that multiple BWPs can be active within the region indicated by the region identifier, and a terminal can use any one of the multiple BWPs within the region indicated by the region identifier.

[0063] For example, BWP1 and BWP2 are associated with region identifier 1. BWP3, BWP4, and BWP5 are associated with region identifier 2.

[0064] The solution provided by the embodiment of this application includes a method in which the BWP included in the configuration information has multiple associations with the region identifier, that is, a method for setting up multiple BWPs for a terminal, and improves the diversity of the configured BWP method in a situation that ensures that a BWP and associated region identifier are set up for a terminal.

[0065] The embodiments of this application are described using a region identifier as an example. In another embodiment, the region identifier can be represented using any of the following identifiers: Type 1: The area identifier is a cell identifier.

[0066] In the embodiments of this application, the cell identifier indicates a single cell, that is, what is indicated by the region identifier indicates a single cell, and the BWP information is associated with the cell identifier.

[0067] In some embodiments, the cell identifier may also be a cell global identifier.

[0068] For example, the cell identifier in question is represented using CGI (Cell Global ID).

[0069] The following explanation will use the example that the region identifier is a cell identifier, and will describe the relationship between BWP information and region identifiers in each case. In other words, the relationship between each piece of BWP information and region identifier in the above embodiment can be explained by replacing the region identifier with a cell identifier. (1) Each domain identifier is associated with one BWP.

[0070] There is a one-to-one correspondence between cell identifiers and BWPs; that is, one cell identifier is associated with one BWP. It can also be understood that a BWP is valid only within the cell indicated by the associated cell identifier.

[0071] For example, BWP1 is associated with cell identifier 1, and BWP2 is associated with cell identifier 2.

[0072] (2) One BWP exists, and that BWP is associated with multiple cell identifiers.

[0073] A single BWP (Block Point Program) is associated with multiple cell identifiers; that is, each cell indicated by multiple cell identifiers corresponds to a single BWP, and that BWP is valid within the cells indicated by those multiple cell identifiers.

[0074] For example, BWP1 is associated with cell identifiers 1 and 2. BWP2 is associated with cell identifiers 3, 4, and 5. BWP3 is associated with cell identifiers 6 and 7.

[0075] (3) Multiple BWPs exist, and each BWP is associated with at least one cell identifier.

[0076] At least one cell identifier may have multiple BWPs associated with it, meaning that multiple BWPs may be active within the cell indicated by the cell identifier, and the terminal may use the BWP information of any one of the multiple BWPs within the cell indicated by the cell identifier.

[0077] For example, BWP1 and BWP2 are associated with cell identifier 1. BWP3, BWP4, and BWP5 are associated with cell identifier 2.

[0078] Type 2: The domain identifier in question is a RAN (Radio Access Network) domain identifier.

[0079] 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 one or more cells share BWP information associated with the RAN area identifier.

[0080] In some embodiments, the RAN area identifier is represented using a RAN area code.

[0081] The following explanation will use the example that the region identifier is a RAN region identifier, and will describe the relationship between BWP information and region identifiers based on each case. In other words, the relationship between each piece of BWP information and region identifier in the above embodiment can be explained by replacing the region identifier with a RAN region identifier: (1) Each RAN area identifier is associated with one BWP.

[0082] A RAN area identifier has a one-to-one correspondence with a BWP; that is, one RAN area identifier is associated with one BWP. It can also be understood that a BWP is valid within the RAN area indicated by the associated RAN area identifier.

[0083] For example, BWP1 is associated with RAN area identifier 1. BWP2 is associated with RAN area identifier 2.

[0084] (2) One BWP exists, and that BWP is associated with multiple RAN area identifiers.

[0085] A single BWP is associated with multiple RAN area identifiers; that is, each RAN area indicated by multiple RAN area identifiers corresponds to a single BWP, and that BWP is valid within the RAN areas indicated by multiple RAN area identifiers.

[0086] 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.

[0087] (3) Multiple BWPs exist, and each BWP is associated with at least one RAN area identifier.

[0088] At least one RAN area identifier is associated with multiple BWPs, meaning that multiple BWPs can be active within the RAN area indicated by the RAN area identifier, and a terminal can use any one of the multiple BWPs within the RAN area indicated by the RAN area identifier.

[0089] 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.

[0090] Third type: The area identifier is a system message area identifier.

[0091] The system message area identifier indicates a system message area, which contains at least one cell; that is, the system message area indicated by the system message area identifier contains one or more cells, and one or more cells are associated with the system message area identifier and share BWP information.

[0092] In some embodiments, the system message area identifier is represented using systemInformationAreaID(system message area identifier).

[0093] The following explanation will assume that the domain identifier is a system message domain identifier, and will describe the relationship between BWP information and domain identifiers based on that relationship. In other words, in the above embodiment, the relationship between each BWP information and domain identifier can be replaced with the system message domain identifier: (1) Each system message area identifier is associated with one BWP.

[0094] There is a one-to-one correspondence between system message area identifiers and BWPs; that is, one system message area identifier is associated with one BWP. It can also be understood that a BWP is valid within the system message area indicated by the associated system message area identifier.

[0095] For example, BWP1 is associated with system message area identifier 1. BWP2 is associated with system message area identifier 2.

[0096] (2) One BWP exists, and this BWP is associated with multiple system message area identifiers.

[0097] A single BWP (Block Pointer) is associated with multiple system message area identifiers; that is, each system message area indicated by multiple system message area identifiers corresponds to a single BWP, and that BWP is valid within the system message areas indicated by multiple system message area identifiers.

[0098] 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.

[0099] (3) Multiple BWPs exist, and each BWP is associated with at least one system message area identifier.

[0100] At least one system message area identifier is associated with multiple BWPs, meaning that multiple BWPs may be valid within the system message area indicated by the system message area identifier, and a terminal may use any one of the multiple BWPs within the system message area indicated by that system message area identifier.

[0101] 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.

[0102] In this application, the embodiments are described as an example in which the region identifier is any one of the cell identifier, RAN region identifier, or system message region identifier. In another embodiment, the region identifier may be a newly defined identifier, and it is not necessary to indicate the region identifier by the identifier in the above embodiment.

[0103] In the solutions provided by the embodiments of this application, the region identifier can be represented using different types of identifiers, that is, different types of identifiers can be used to indicate regions corresponding to BWP information, thereby extending the representation of region identifiers and ensuring accuracy in indicating regions associated with BWP information.

[0104] Based on the embodiment shown in Figure 2, after the network device has configured BWP information for the terminal, the terminal can transmit an uplink positioning reference signal based on the configured BWP information. Referring to Figure 3, the method includes the following steps: Step 301: The terminal, while in an RRC idle state and / or RRC inactive state, transmits an uplink positioning reference signal to a network device based on at least one BWP piece of information.

[0105] In embodiments of this application, when a terminal is in an RRC idle state and / or RRC inactive state, the terminal transmits an uplink reference signal to the network device based on at least one BWP piece of information already set by the network device.

[0106] In some embodiments, if each BWP in at least one BWP information is associated with a region identifier, the terminal can transmit an uplink reference signal to a network device based on at least one BWP information and at least one region identifier associated with each BWP information.

[0107] The step of a terminal transmitting an uplink positioning reference signal to a network device based on at least one BWP piece of information while in an RRC idle state and / or RRC inactive state includes any of the following solutions: In some embodiments, the terminal transmits an uplink positioning reference signal based on the BWP information corresponding to the region identifier, while the terminal is in an RRC idle state and / or RRC inactive state, and the region in which the terminal is located is associated with BWP information.

[0108] In the embodiments of this application, when a terminal is in an RRC idle state and / or an RRC inactive state, and the area where the terminal is located is located in an area indicated by an area identifier already set by a network device, BWP information associated with the area where the terminal is located is shown, and an uplink positioning reference signal is transmitted based on the BWP information corresponding to the area identifier belonging to the area where the terminal is located.

[0109] After determining the region identifier corresponding to the area where the terminal is located, the BWP information associated with that region identifier is determined. Furthermore, if a BWP is determined based on that BWP information, the terminal can transmit an uplink positioning reference signal using the already determined BWP.

[0110] For example, each BWP information set by a network device is associated with a single area identifier, and this area identifier is a cell identifier. The network device sets BWP information 1, BWP information 2, and BWP information 3 for a 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, BWP information 2 is associated with cell identifier 2 corresponding to cell 2. The terminal can then transmit an uplink positioning reference signal to the network device based on BWP information 2.

[0111] Furthermore, for example, each BWP information set by a network device is associated with multiple area identifiers, and these area identifiers are cell identifiers. The network device sets BWP information 1 and BWP information 2 for a terminal. BWP information 1 is associated with cell identifier 1 and cell identifier 2, where cell identifier 1 points to cell 1 and cell identifier 2 points to cell 2. BWP information 2 is associated with cell identifier 3, cell identifier 4, and cell identifier 5, where cell identifier 3 points to cell 3, cell identifier 4 points to cell 4, and cell identifier 5 points to cell 5. If the area where the terminal is located belongs to the area covered by cell 2, BWP information 2 is associated with cell identifier 2 corresponding to cell 2. Based on BWP information 2, the terminal can transmit an uplink positioning reference signal to the network device.

[0112] Furthermore, for example, each BWP information set by a network device is associated with multiple area identifiers, which are RAN area identifiers. The network device sets BWP information 1 and BWP information 2 for a terminal. BWP information 1 is associated with RAN area identifier 1 and RAN area identifier 2, where RAN area identifier 1 points to cells 1 and 2, and RAN area identifier 2 points to cells 3, 4, and 5. BWP information 2 is associated with RAN area identifiers 3, 4, and 5, where RAN area identifier 3 points to cells 6 and 7, RAN area identifier 4 points to cells 8, 9, and 10, and RAN area identifier 5 points to cells 11 and 12. If the area where the terminal is located belongs to the area covered by cell 7, BWP information 2 is associated with RAN area identifier 3 corresponding to cell 7. Based on BWP information 2, the terminal can transmit an uplink positioning reference signal to the network device.

[0113] The embodiments described in this application are illustrative examples of related relationships, and this application is not limited to the above examples. Network devices may also configure other related relationships for terminals.

[0114] In some other embodiments, the terminal transmits an uplink positioning reference signal based on an initial BWP, while the RRC is idle and / or RRC is inactive and the region where the terminal is located is not associated with BWP information.

[0115] The initial BWP may be a BWP configured by a network device for a terminal via a system message broadcast scheme, or a BWP agreed upon by a protocol between the network device and the terminal, or a BWP configured using any other method, and the embodiments of this application are not limited.

[0116] In embodiments of this application, it is explained that if a terminal is in an RRC idle state and / or an RRC inactive state and there is no BWP information associated with the region in which the terminal is located, the terminal cannot transmit an uplink positioning reference signal using BWP information already set by a network device; however, if the network device has already provided initial BWP information for the terminal, the terminal can transmit an uplink positioning reference signal based on the initial BWP.

[0117] After it is determined that the terminal is not located in the region corresponding to the region identifier set by the network device, the initial BWP can be determined, and the terminal can transmit an uplink positioning reference signal with the already determined initial BWP.

[0118] For example, each BWP information set by a network device is associated with a single area identifier, which is a cell identifier, and the network device sets BWP information 1, BWP information 2, and BWP information 3 for a 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, and if the area where the terminal is located does not belong to an area covered by any of the cells 1, 2, and 3, the area where the terminal is located is not associated with BWP information, and the terminal can transmit an uplink positioning reference signal to the network device based on the initial BWP.

[0119] Furthermore, for example, each BWP information set by a network device is associated with multiple area identifiers, and these area identifiers are cell identifiers. The network device sets BWP information 1 and BWP information 2 for a terminal, and BWP information 1 is associated with cell identifier 1 and cell identifier 2, where cell identifier 1 points to cell 1 and cell identifier 2 points to cell 2. BWP information 2 is associated with cell identifier 3, cell identifier 4, and cell identifier 5, where cell identifier 3 points to cell 3, cell identifier 4 points to cell 4, and cell identifier 5 points to cell 5. If the area where the terminal is located does not belong to an area covered by any of the cells 1, 2, 3, 4, and 5, the area where the terminal is located is not associated with BWP information. The terminal can then transmit an uplink positioning reference signal to the network device based on the initial BWP.

[0120] Furthermore, for example, each BWP information set by a network device is associated with multiple area identifiers, and these area identifiers are RAN area identifiers, and the network device sets 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 points to cell 1 and cell 2, RAN area identifier 2 points to cell 3, cell 4 and cell 5, and BWP information 2 is associated with RAN area identifier 3, RAN area identifier 4 and RAN area identifier 5, and the R If AN area identifier 3 indicates cells 6 and 7, RAN area identifier 4 indicates cells 8, 9 and 10, and RAN area identifier 5 indicates cells 11 and 12, and the area where the terminal is located does not belong to an area covered by any of the cells 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12, then the area where the terminal is located is described as not being associated with BWP information, and the terminal can transmit an uplink positioning reference signal to the network device based on the initial BWP.

[0121] The embodiments described in this application are illustrative examples of related relationships, and this application is not limited to the above examples. Network devices may also configure other related relationships for terminals.

[0122] In this embodiment, the example described is one in which an uplink positioning reference signal is transmitted based on an initial BWP. In another embodiment, the terminal does not transmit an uplink positioning reference signal and releases at least one BWP piece of information set by the network device.

[0123] The terminal is in an RRC idle state and / or RRC inactive state, and the region where the terminal is located is not associated with BWP information, and at least one BWP piece of information is released.

[0124] In embodiments of the present application, it is explained that if a terminal is in an RRC idle state and / or RRC inactive state and the region where the terminal is located is not associated with BWP information, the terminal cannot transmit an uplink positioning reference signal using BWP information already set by the network device, and for such a terminal, the terminal does not transmit an uplink positioning reference signal and releases at least one BWP information already set by the network device.

[0125] For example, each BWP information set by a network device is associated with one area identifier, and the area identifier is a cell identifier. The network device sets BWP information 1, BWP information 2, and BWP information 3 for a terminal. BWP information 1 is associated with cell identifier 1, which points to cell 1. BWP information 2 is associated with cell identifier 2, which points to cell 2. BWP information 3 is associated with cell identifier 3, which points to cell 3. If the area where the terminal is located does not belong to an area covered by any of the cells 1, 2, and 3, the area where the terminal is located is described as not being associated with BWP information, and the terminal releases at least one BWP information already set by the network device.

[0126] Furthermore, for example, each BWP information set by a network device is associated with multiple area identifiers, and these area identifiers are cell identifiers. The network device sets BWP information 1 and BWP information 2 for a terminal. BWP information 1 is associated with cell identifier 1 and cell identifier 2, where cell identifier 1 points to cell 1 and cell identifier 2 points to cell 2. BWP information 2 is associated with cell identifier 3, cell identifier 4, and cell identifier 5, where cell identifier 3 points to cell 3, cell identifier 4 points to cell 4, and cell identifier 5 points to cell 5. If the area where the terminal is located does not belong to an area covered by any of the cells 1, 2, 3, 4, and 5, the area where the terminal is located is not associated with BWP information, and the terminal releases at least one BWP information already set by the network device.

[0127] Furthermore, for example, each BWP information set by a network device is associated with multiple area identifiers, and these area identifiers are RAN area identifiers. The network device sets BWP information 1 and BWP information 2 for a terminal. BWP information 1 is associated with RAN area identifier 1 and RAN area identifier 2, where RAN area identifier 1 points to cells 1 and 2, RAN area identifier 2 points to cells 3, 4 and 5, and BWP information 2 is associated with RAN area identifier 3, RAN area identifier 4, and RAN area identifier 5. If the RAN area identifier 3 points to cells 6 and 7, the RAN area identifier 4 points to cells 8, 9, and 10, and the RAN area identifier 5 points to cells 11 and 12, and the area where the terminal is located does not belong to an area covered by any of the cells 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12, then the area where the terminal is located is described as not being associated with BWP information, and the terminal releases at least one BWP piece of information already configured by the network device.

[0128] In this embodiment, only the example of a terminal releasing at least one BWP information already set by the network device is described. In another embodiment, the network device further sets up an uplink positioning reference signal setting for the terminal, and if it is decided that the terminal will not transmit an uplink positioning reference signal, the terminal releases not only at least one BWP information already set by the network device, but also an uplink positioning reference signal setting that has already been set.

[0129] In some embodiments, it is necessary to determine whether BWP information is associated with the region where the terminal is located, and the terminal can determine whether BWP information is associated with the region where the terminal is located based on the region identifier associated with each piece of BWP information.

[0130] In embodiments of the present application, after a terminal receives at least one BWP information set by a network device, it can determine the region to which the BWP information is associated based on the region identifier associated with each BWP information, and the terminal can further determine the region to which it is located. Thus, if it is determined that the region to which the terminal is located is within the region indicated by the region identifier, the region to which the terminal is located is described as being associated with the BWP information, and if it is determined that the region to which the terminal is located is not within the region indicated by the region identifier, the region to which the terminal is located is described as being not associated with the BWP information.

[0131] Step 302: The network device receives an uplink positioning reference signal transmitted by the terminal based on at least one BWP piece of information, the uplink positioning reference signal is transmitted by the terminal while it is in an RRC idle state and / or RRC inactive state.

[0132] In embodiments of this application, a network device sets at least one BWP information on a terminal, the set at least one BWP information is used by the terminal to transmit an uplink positioning reference signal in the RRC idle state and / or RRC inactive state, and the network device can receive the uplink positioning reference signal transmitted by the terminal based on the at least one BWP information.

[0133] In the solutions provided by embodiments of this application, when a terminal is in an RRC idle state and / or RRC inactive state, it transmits an uplink positioning reference signal to a network device based on at least one BWP piece of information, meaning that after the terminal moves to a region indicated by a region identifier, the terminal can still transmit an uplink positioning reference signal based on already configured BWP piece of information, facilitating positioning by the network device, extending the method of positioning the terminal, and ensuring the stability of terminal positioning.

[0134] Based on the embodiment shown in Figure 3, the network device needs to receive an uplink positioning reference signal transmitted by the terminal and then perform positioning based on that uplink positioning reference signal, referring to Figure 4, and the method includes the following steps: Step 401: Position the terminal based on the network device uplink positioning reference signal.

[0135] In embodiments of this application, once a network device sets BWP information for transmitting an uplink positioning reference signal for a terminal, after the terminal transmits the uplink positioning reference signal, the network device can position the terminal based on the received uplink positioning reference signal.

[0136] Step 402: Obtain the location information of the network device terminal.

[0137] In the embodiments of this application, after a network device positions a terminal, it can obtain the location of the terminal and further determine the terminal's location information.

[0138] In some embodiments, network devices position terminals based on UL TDOA (Uplink Time Difference of Arrival) positioning technology.

[0139] In the embodiments of this application, the network device configures a plurality of TRPs, each TRP capable of receiving an uplink positioning reference signal transmitted by a terminal. For each TRP, the network device receives the time of the uplink positioning reference signal and the TRP's reference time based on the TRP, and determines the UL RTOA (Uplink Relative Time of Arrival). The network device then determines the terminal's location information based on the acquired UL RTOA and the location information of each TRP in the plurality of TRPs.

[0140] Selectively, time synchronization between multiple TRPs configured by network devices is used to determine terminal location information based on UL RTOA, eliminating interference due to time asynchronous operation between multiple TRPs and improving the accuracy of the determined terminal location information.

[0141] In the solutions provided by embodiments of this application, when a terminal is in an RRC idle state and / or RRC inactive state, it transmits an uplink positioning reference signal to a network device based on at least one BWP piece of information, meaning that after the terminal moves to a region indicated by a region identifier, the terminal can still transmit an uplink positioning reference signal based on already set BWP information, facilitating positioning by the network device, further extending the method by which the network device acquires the terminal's location information and positions the terminal, and ensuring the stability of terminal positioning.

[0142] Furthermore, the above-described embodiments can be divided into new embodiments, or combined with other embodiments to form new embodiments, and this application is not limited to combinations between embodiments.
