[0021] The application scenario of this application will be described below. FIG. 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 plural, and one or more terminals 10 may be distributed within a cell managed by each network device 20. The terminals 10 may include handheld devices with wireless communication capabilities, in-vehicle devices, wearable devices, computing devices or other devices connected to a wireless modem, as well as various types of user equipment (UE), mobile stations (MS), etc. For ease of explanation, in the embodiments of the present application, the above-mentioned devices will be collectively referred to as terminals.

[0023] The network device 20 is a device disposed in an access network and provides wireless communication functions for the terminal 10. For ease of description, in the embodiments of the present application, devices providing wireless communication functions for the terminal 10 are collectively referred to as network devices. A connection can be established between the network device 20 and the terminal 10 via an air interface, and communication is performed through the connection, including signaling and data exchange. There may be multiple network devices 20, and two adjacent network devices 20 may communicate with each other via a wired or wireless method. The terminal 10 can switch between different network devices 20, i.e., establish a connection with a different network device 20.

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

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

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

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

[0028] A step in which the network device sends setting information to the terminal, and at least one BWP information can be set to the terminal through the setting information, each BWP information being associated with an area identifier, and the area corresponding to the BWP information is indicated through the area identifier, and further, the terminal determines the BWP information set for the terminal by the network device and the area corresponding to the BWP information.

[0029] In some embodiments, the region identifier indicates at least one cell, and the region identifier is an identifier corresponding to BWP information, i.e., 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, the area identifier associated with the BWP information indicates cell 1 and cell 2, and when the terminal is located in cell 1, BWP information is associated with cell 1, the BWP information is valid, and the terminal can use the BWP information; when the terminal is located in cell 3, and the cell 3 is located other than cell 1 and cell 2, BWP information is not associated with cell 3, the BWP information is invalid, and the terminal cannot use the BWP information.

[0031] In some embodiments, the terminal transmits an uplink positioning reference signal to the network device, and then 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 spacing refers to the spacing between two adjacent subcarriers, for example, the subcarrier spacing may be 15 KHz (kilohertz), 30 KHz, or other values.

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

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

[0036] (3) Frequency domain location of BWP.

[0037] The frequency domain location is the location of the indicated BWP in the frequency domain.

[0038] (4) Bandwidth of BWP.

[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] It should be noted that the steps performed by the network device may form an embodiment alone, and the steps performed by the terminal may also form an embodiment alone, and the present application is not limited in this respect.

[0042] In the solution provided by the embodiments of the present application, a terminal receives at least one BWP information, and the at least one BWP information is associated with an area identifier. The BWP information is used to transmit an uplink positioning reference signal when the terminal is in an RRC idle state and / or an inactive state. That is, after the terminal moves into the area indicated by the area identifier, the terminal can still transmit an uplink positioning reference signal based on the already set BWP information, which can facilitate positioning by network devices, enhance the manner of positioning the terminal, and ensure the stability of positioning the terminal.

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

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

[0045] For example, obtaining BWP information from an LMF refers to the BWP information for transmitting the uplink positioning reference signal of a neighboring cell obtained by a network device from an LMF via an NRPPa.

[0046] In an embodiment of the present application, the LMF is a network element in a core network, and the LMF can obtain BWP information for transmitting uplink positioning reference signals in neighboring cells. The network device communicates with the LMF via an NRPPa, so that the network device can obtain the BWP information for transmitting uplink positioning reference signals from the LMF via the NRPPa.

[0047] The following describes how to obtain BWP information from LMF for a network device.

[0048] Alternatively, the LMF network element may send BWP request information to a neighboring cell, and the BWP request information may be used to obtain the BWP information of the neighboring cell. The neighboring cell may receive the BWP request information sent by the LMF network element, and in response to the BWP request information, send the BWP information of the neighboring cell to the LMF. After the LMF receives the BWP information sent by the neighboring cell, the BWP information of the neighboring cell is carried in an NRPPa message, and the LMF sends the NRPPa message to the network device. The BWP information includes the cell identifier of the neighboring cell.

[0049] Alternatively, the network device may send BWP request information to the LMF network element, and after the LMF network element receives the BWP request information, the LMF network element may send BWP request information to a neighboring cell in response to the BWP request information, which is used to obtain the BWP information of the neighboring cell. The neighboring cell may receive the BWP request information sent by the LMF network element and send the BWP information of the neighboring cell to the LMF in response to the BWP request information. After the LMF receives the BWP information sent by the neighboring cell, the BWP information of the neighboring cell is carried in an NRPPa message and sent to the network device. The BWP information includes the cell identifier of the neighboring cell.

[0050] In addition, obtaining BWP information from the Xn interface refers to the BWP information for transmitting the uplink positioning reference signal of the neighboring cell obtained by the network device via the Xn interface, that is, the network device obtains BWP information through another network device, and network devices can also communicate with each other via the Xn interface, so that the network device obtains BWP information for transmitting the uplink positioning reference signal from the network device of the neighboring cell via the Xn interface.

[0051] The following describes how a network device can obtain BWP information from other network devices.

[0052] When the network device is a network device of a serving cell and the other network device is a network device of a neighboring cell, the serving cell sends BWP request information to the neighboring cell via the Xn interface, and the neighboring cell receives the BWP request information and returns BWP information to the serving cell via the Xn interface in response to the BWP request information, the BWP information including the cell identifier of the neighboring cell.

[0053] It should be noted that the serving cell in the embodiment of the present application is the cell that sets the BWP information for the terminal, and the neighboring cell is the neighboring cell for the terminal.

[0054] Based on the embodiment shown in FIG. 2, the relationship between BWP information and area identifiers includes several types, and each relationship will be described below.

[0055] First type: each region identifier is associated with one BWP.

[0056] There is a one-to-one correspondence between region identifiers and BWPs, i.e., one region identifier is associated with one BWP, and the BWP can be understood to be valid 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] Second type: There is one BWP, and the BWP is associated with multiple region identifiers.

[0059] A BWP is associated with multiple region identifiers, meaning that the regions indicated by the multiple region identifiers all correspond to a single BWP, and the BWP is valid within the regions indicated by the 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: There are multiple BWPs, each associated with at least one region identifier.

[0062] At least one region identifier is associated with multiple BWPs, i.e., multiple BWPs are valid within the region indicated by the region identifier, and the 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] In the solution provided by the embodiment of the present application, the BWP included in the configuration information has multiple association relationships with the area identifier, i.e., includes multiple ways of configuring BWPs for a terminal, thereby improving the diversity of the ways of configuring BWPs in situations where it is necessary to configure a BWP and associated area identifiers for the terminal.

[0065] In the embodiments of the present application, the region identifier is described as an example. In another embodiment, the region identifier can be represented using any of the following identifiers: First type: the area identifier is a cell identifier.

[0066] In the embodiment of the present application, the cell identifier indicates one cell, that is, what is indicated by the area identifier indicates one 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 is expressed using a CGI (Cell Global ID).

[0069] The following description will be based on the relationship between the BWP information and the area identifier, taking the case where the area identifier is a cell identifier as an example. In other words, the relationship between each BWP information and the area identifier in the above embodiment can be replaced with the area identifier by the cell identifier, (1) Each area identifier is associated with one BWP.

[0070] There is a one-to-one correspondence between cell identifiers and BWPs, i.e., one cell identifier is associated with one BWP, which can also be understood as being valid within the cell indicated by the associated cell identifier.

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

[0072] (2) There is one BWP, and the BWP is associated with multiple cell identifiers.

[0073] One BWP is associated with multiple cell identifiers, that is, the cells indicated by the multiple cell identifiers all correspond to one BWP, and the BWP is valid in the cells indicated by the multiple cell identifiers.

[0074] 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.

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

[0076] At least one cell identifier is associated with multiple BWPs, i.e., multiple BWPs are valid in the cell indicated by the cell identifier, and the terminal can use BWP information of any one of the multiple BWPs in 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] Second type: the area identifier is a RAN (Radio Access Network) area identifier.

[0079] The RAN area identifier indicates a RAN area, and the RAN area includes at least one cell, i.e., the RAN area indicated by the RAN area identifier includes one or more cells, and the one or more cells are associated with the RAN area identifier and share BWP information.

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

[0081] The following description will be based on the relationship between the BWP information and the area identifier, taking the case where the area identifier is a RAN area identifier as an example. That is, in the relationship between the BWP information and the area identifier in the above embodiment, the area identifier can be replaced with the RAN area identifier: (1) Each RAN domain identifier is associated with one BWP.

[0082] A RAN domain identifier has a one-to-one correspondence with a BWP, i.e., one RAN domain identifier is associated with one BWP, and the BWP can also be understood to be valid within the RAN domain indicated by the associated RAN domain identifier.

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

[0084] (2) There is one BWP, and the BWP is associated with multiple RAN domain identifiers.

[0085] One BWP is associated with multiple RAN domain identifiers, i.e., the RAN domains indicated by the multiple RAN domain identifiers all correspond to one BWP, and the BWP is valid within the RAN domains indicated by the multiple RAN domain identifiers.

[0086] For example, BWP1 is associated with RAN domain identifier 1 and RAN domain identifier 2. BWP2 is associated with RAN domain identifier 3, RAN domain identifier 4, and RAN domain identifier 5. BWP3 is associated with RAN domain identifier 6 and RAN domain identifier 7.

[0087] (3) There are multiple BWPs, and each BWP is associated with at least one RAN domain identifier.

[0088] At least one RAN domain identifier is associated with multiple BWPs, i.e., multiple BWPs are valid within the RAN domain indicated by the RAN domain identifier, and the terminal can use any one of the multiple BWPs within the RAN domain indicated by the RAN domain identifier.

[0089] For example, BWP1 and BWP2 are associated with RAN domain identifier 1. BWP3, BWP4, and BWP5 are associated with RAN domain identifier 2.

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

[0091] The system message area identifier indicates a system message area, and the system message area includes at least one cell, i.e., the system message area indicated by the system message area identifier includes one or more cells, and the 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.

[0093] The following description will be based on the relationship between the BWP information and the area identifier, taking the case where the area identifier is a system message area identifier as an example. In other words, the relationship between each BWP information and the area identifier in the above embodiment can be replaced with the system message area identifier: (1) Each system message area identifier is associated with one BWP.

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

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

[0096] (2) There is one BWP, and the BWP is associated with multiple system message area identifiers.

[0097] One BWP is associated with multiple system message area identifiers, i.e., the system message areas indicated by the multiple system message area identifiers all correspond to one BWP, and the BWP is valid within the system message areas indicated by the 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) There are multiple BWPs, each associated with at least one system message area identifier.

[0100] At least one system message area identifier is associated with multiple BWPs, i.e., multiple BWPs are valid within the system message area indicated by the system message area identifier, and the terminal can use any one of the multiple BWPs within the system message area indicated by the system message area identifier.

[0101] For example, BWP1 and BWP2 are associated with system message domain identifier 1. BWP3, BWP4, and BWP5 are associated with system message domain identifier 2.

[0102] In the embodiment of the present application, the region identifier is any one of a cell identifier, a RAN region identifier, and a 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 solution provided by the embodiments of the present application, the region identifier can be represented using different types of identifiers, i.e., different types of identifiers are used to indicate the region corresponding to the BWP information, thereby extending the representation method of the region identifier and ensuring the accuracy of indicating the region with which the BWP information is associated.

[0104] Based on the embodiment shown in Figure 2, after the network device configures 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: A terminal sends an uplink positioning reference signal to a network device in an RRC idle state and / or an RRC inactive state based on at least one BWP information.

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

[0106] In some embodiments, if each BWP information in the at least one BWP information is associated with a region identifier, the terminal can transmit 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.

[0107] The step of transmitting, by the terminal, an uplink positioning reference signal to the network device based on the at least one BWP information in an RRC idle state and / or an 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 a region identifier when in an RRC idle state and / or an RRC inactive state and the region in which the terminal is located is associated with BWP information.

[0108] In an embodiment of the present application, when the terminal is in an RRC idle state and / or an RRC inactive state and the area in which the terminal is located is located in an area indicated by an area identifier already set by the network device, the terminal indicates BWP information associated with the area in which the terminal is located, and further transmits an uplink positioning reference signal based on the BWP information corresponding to the area identifier belonging to the area in which the terminal is located.

[0121] It should be noted that the embodiments of the present application are described using association relationships as examples, and the present application is not limited to the above examples, and the network device may also set other association relationships for the terminal.

[0122] In addition, the embodiments of the present application will be described taking the example of transmitting an uplink positioning reference signal based on the initial BWP as an example, in another embodiment, the terminal does not transmit an uplink positioning reference signal, and releases at least one BWP information set by the network device.

[0123] The terminal is in an RRC idle state and / or an RRC inactive state, the area in which the terminal is located is not associated with BWP information, and releases at least one BWP information.

[0124] In the embodiments of the present application, it is described that when a terminal is in an RRC idle state and / or an RRC inactive state and the area 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 a network device, and for the terminal, the terminal will not transmit an uplink positioning reference signal and will release at least one BWP information already set by a network device.

[0125] For example, each BWP information set by the 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 the terminal; BWP information 1 is associated with cell identifier 1, and the cell identifier 1 indicates cell 1; BWP information 2 is associated with cell identifier 2, and the cell identifier 2 indicates cell 2; BWP information 3 is associated with cell identifier 3, and the cell identifier 3 indicates cell 3; if the area where the terminal is located does not belong to the area covered by any of cells 1, 2, and 3, it is described that 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.

[0126] Further, for example, each BWP information set by the network device is associated with multiple area identifiers, the area identifiers are cell identifiers, the network device sets BWP information 1 and BWP information 2 for the terminal, BWP information 1 is associated with cell identifier 1 and cell identifier 2, the cell identifier 1 indicates cell 1, the cell identifier 2 indicates cell 2, BWP information 2 is associated with cell identifier 3, cell identifier 4, and cell identifier 5, the cell identifier 3 indicates cell 3, the cell identifier 4 indicates cell 4, and the cell identifier 5 indicates cell 5, and if the area where the terminal is located does not belong to the area covered by any of cells 1, 2, 3, 4, and 5, it is described that 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] Also, for example, each BWP information set by the network device is associated with a plurality of area identifiers, the area identifiers are RAN area identifiers, the network device sets BWP information 1 and BWP information 2 for the terminal, the BWP information 1 is associated with RAN area identifier 1 and RAN area identifier 2, the RAN area identifier 1 indicates cell 1 and cell 2, the RAN area identifier 2 indicates cell 3, cell 4 and cell 5, the 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 indicates cell 6 and cell 7, the RAN area identifier 4 indicates cell 8, cell 9, and cell 10, and the RAN area identifier 5 indicates cell 11 and cell 12, and the area in which the terminal is located does not belong to the area covered by any of cells 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12, it is described that the area in which 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.

[0128] In addition, the embodiment of the present application only describes the terminal releasing at least one BWP information already set by the network device as an example. In another embodiment, the network device further sets an uplink positioning reference signal configuration for the terminal, and when it is determined that the terminal will not transmit an uplink positioning reference signal, the terminal not only releases the at least one BWP information already set by the network device, but also releases the already set uplink positioning reference signal configuration.

[0129] In some embodiments, it is necessary to determine whether BWP information is associated with the area in which the terminal is located, and the terminal can determine whether BWP information is associated with the area in which the terminal is located based on the area identifier associated with each BWP information.

[0130] In an embodiment of the present application, after a terminal receives at least one BWP information set by a network device, it can determine the area to which the BWP information is associated based on the area identifier associated with each BWP information, and the terminal can further determine the area in which it is located; thus, if the terminal determines that the area in which it is located is within the area indicated by the area identifier, it is described that the area in which it is located is associated with the BWP information, and if the terminal determines that the area in which it is located is not located within the area indicated by the area identifier, it is described that the area in which it is located is 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 information, and the uplink positioning reference signal is transmitted when the terminal is in an RRC idle state and / or an RRC inactive state.

[0132] In an embodiment of the present application, a network device configures at least one BWP information for a terminal, and the configured at least one BWP information is used by the terminal to transmit an uplink positioning reference signal in an RRC idle state and / or an RRC inactive state, and for the network device, 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 solution provided by the embodiments of the present application, when the terminal is in an RRC idle state and / or an RRC inactive state, it transmits an uplink positioning reference signal to the network device based on at least one BWP information, that is, after the terminal moves into the area indicated by the area identifier, the terminal can still transmit an uplink positioning reference signal based on the already set BWP information, which can facilitate positioning by the network device, extend the manner of positioning the terminal, and ensure the stability of positioning the terminal.

[0134] Based on the embodiment shown in FIG. 3 , after receiving the uplink positioning reference signal transmitted by the terminal, the network device needs to further perform positioning based on the uplink positioning reference signal. Referring to FIG. 4 , the method includes the following steps: Step 401: Position a terminal based on a network device uplink positioning reference signal.

[0135] In an embodiment of the present application, when 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 location information of the network device terminal.

[0137] In the embodiment of the present application, after the network device locates the terminal, it can obtain the location where the terminal is located, and further determine the location information of the terminal.

[0138] In some embodiments, the network device positions the terminal based on an UL TDOA (Uplink Time Difference of Arrival) positioning technique.

[0139] In an embodiment of the present application, a network device configures multiple TRPs, each of which can receive 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 reference time of the TRP according to each TRP, and determines an UL Relative Time of Arrival (RTOA). The network device determines the location information of the terminal according to the obtained UL RTOAs and the location information of each TRP in the multiple TRPs.

[0140] Alternatively, when determining terminal location information based on UL RTOA by time synchronization between multiple TRPs set by the network device, interference caused by time asynchronous between multiple TRPs can be eliminated, thereby improving the accuracy of the determined terminal location information.

[0141] In the solution provided by the embodiments of the present application, when the terminal is in an RRC idle state and / or an RRC inactive state, it transmits an uplink positioning reference signal to the network device based on at least one BWP information, that is, after the terminal moves into the area indicated by the area identifier, the terminal can still transmit an uplink positioning reference signal based on the already set BWP information, which facilitates the network device to perform positioning, further enhances the manner in which the network device obtains the location information of the terminal and positions the terminal, and ensures the stability of positioning the terminal.

[0142] It should be noted that the above-described embodiments can be separated into new embodiments or can be combined with other embodiments to form new embodiments, and the present application does not limit the combination of embodiments.
