The communication system can be used to support 4G network access technologies, such as Long Term Evolution (LTE) access technology, or 5G network access technologies, such as New Radio Access Technology (New RAT), or other future wireless communication technologies. It should be noted that in the communication system, the number of network side devices 12 and terminal devices 11 can be one or more. Figure 1 The number of network side devices 12 and terminal devices 11 in the communication system shown is only an example, and the present disclosure does not limit the number of network side devices 12 and terminal devices 11.

[0047] Figure 1 The network side device 12 in the communication system can be used to support terminal device 11 access, for example, the network side device 12 can be an evolved Node B (eNB or eNodeB) in LTE; the network side device 12 can also be a next generation Node B (gNB or gNodeB) in a 5G network; the network side device 12 can also be a wireless access network (NG Radio Access Network, NG-RAN) device in a 5G network; the network side device 12 can also be a base station in a future evolved public land mobile network (PLMN), a broadband network service gateway (BNG), a convergence switch, or a non-3GPP (3rd Generation Partnership Project, 3GPP) access device, etc.

[0048] Optionally, the network-side device 12 in the embodiments of the present disclosure can include various forms of base stations, such as macro base stations, micro base stations (also known as small stations), relay stations, access points, 5G base stations or future base stations, satellites, transmitting and receiving points (TRPs), transmitting points (TPs), mobile switching centers, and devices that perform base station functions in device-to-device (D2D), machine-to-machine (M2M), Internet of Things (IoT), vehicle-to-everything (V2X), or other communications, and the like, and the embodiments of the present disclosure do not make specific limitations thereon. For the convenience of description, the apparatuses that provide wireless communication functions for the terminal device 11 in all the embodiments of the present disclosure are collectively referred to as the network-side device 12 or the base station.

[0049] It should be noted that in the embodiments of the present disclosure, the network-side device can be a location server or a serving base station.

[0050] The signaling between the location server and the terminal device can include at least one of the following: LTE positioning protocol (LPP), NR positioning protocol (NRPP), combination of NR positioning protocol annex (NRPPa) and the first signaling, combination of LTE positioning protocol annex (LPPa) and the first signaling, the first signaling being signaling between the base station and the terminal device. Here, the first signaling can include at least one of the following: radio resource control (RRC), medium access control control element (MAC CE), downlink control information (DCI), message 1 (Msg1), message 3 (Msg3), broadcast signaling, and paging (Paging) signaling.

Multiple terminal devices 11 can also communicate with each other. The terminal device 11 can be static or mobile, and the present disclosure does not limit this.

[0052] In NR positioning measurement, the terminal device can usually only support measuring the positioning reference signal PRS on a single carrier to achieve positioning measurement. In order to improve the positioning accuracy, carrier measurement based on CA (Carrier Aggregation) is introduced, at this time the terminal device can measure the PRS positioning reference signal on the currently configured CA carrier. However, the terminal device measures PRS signals of different bandwidths, and the corresponding measurement accuracy will be different. In other words, the wider the measured PRS bandwidth, the higher the corresponding measurement accuracy will be. If the measurement accuracy requirement is defined based on the minimum PRS bandwidth only, it may affect the positioning accuracy and performance.

[0053] Figure 2 FIG. 1 is a flowchart of a communication method according to some embodiments. As shown in FIG. 1, the communication method can be used in a terminal device, including the following steps. Figure 2

[0054] In step S110, a measurement bandwidth of a positioning reference signal PRS is sent to a network side device.

[0055] ​In some embodiments, the terminal device can send a measurement bandwidth of a positioning reference signal PRS to the network-side device, to indicate that the terminal device acquires a target accuracy requirement corresponding to the measurement bandwidth of the positioning reference signal PRS, and based on the target accuracy requirement, the embodiments of the present disclosure can not only acquire more accurate and effective position information, but also evaluate the measurement results of the terminal device.

[0056] In the embodiments of the present disclosure, the terminal device can send the measurement bandwidth of the positioning reference signal PRS to the network-side device through a ProvideLocationInformation in an LPP message. In other words, the terminal device can report the indication information of the measured PRS reference signal bandwidth in the information element (IE) ProvideLocationInformation. The network-side device here can be a location server, that is, the terminal device can send the measurement bandwidth of the positioning reference signal PRS to the location server.

[0057] As an optional way, after performing the measurement related to the positioning reference signal PRS and obtaining the measurement result, the terminal device can send the measurement bandwidth of the positioning reference signal PRS obtained by the terminal device to the network-side device, to instruct the network-side device to perform a position information acquisition operation or a measurement result evaluation operation based on the measurement bandwidth of the positioning reference signal PRS. Here, the measurement related to the positioning reference signal PRS can be performed based on the measurement configuration information sent by the network-side device.

[0058] Figure 3 is a communication timing diagram of a communication method according to some embodiments. As shown in Figure 3 , the terminal device can send a measurement bandwidth of a positioning reference signal PRS to the network-side device.

[0059] The embodiments of the present disclosure provide that the terminal device can send the measurement bandwidth of the positioning reference signal PRS to the network-side device, so as to improve the positioning accuracy and the positioning performance, and thus solve the problem that different measurement bandwidths correspond to different measurement accuracies.

[0060] Figure 4 is a flowchart of a communication method according to some other embodiments. As shown in Figure 4 , the communication method can be used in a terminal device, including the following steps.

[0061] In step S210, target configuration information is received from the network-side device.

[0062] In the embodiments of the present disclosure, the terminal device can receive target configuration information from the network side device, wherein the target configuration information can include at least one of measurement configuration information of positioning measurement, reporting configuration information, and configuration information of a positioning reference signal (PRS).

[0063] Here, the terminal device can receive the target configuration information from the network side device through an LPP message. As a specific implementation, the LPP message can be an information element (IE) ProvideAssistanceData message or an IE RequestLocationInformation message. The IE RequestLocationInformation message can include configuration information of the PRS, which can include indication information of whether to report the bandwidth of the PRS.

[0064] It should be noted that the use of “or” to separate a plurality of embodiments or features does not mean that some of the features cannot be implemented. In addition, the embodiments of the present disclosure can be combined with other embodiments or implementation manners of the communication method for the terminal device without contradiction, which will not be described here.

[0065] Figure 5 is a communication timing diagram of a communication method according to another embodiment. As shown in Figure 5 The terminal device can receive target configuration information from the network side device.

[0066] The embodiments of the present disclosure provide that the terminal device can send the measurement bandwidth of the PRS to the network side device, which can improve the positioning accuracy and positioning performance, and thus can solve the problem of different measurement bandwidths corresponding to different measurement accuracies. In addition, the terminal device can receive the target configuration information sent by the network side device, and based on the target configuration information, the terminal device can more flexibly and effectively communicate with the network side device.

[0067] Figure 6 is a flowchart of a communication method according to still another embodiment. As shown in Figure 6 The communication method can be used in a terminal device, including the following steps.

[0068] In step S310, target configuration information is received from the network side device.

[0069] The specific implementation of step S310 has been described in detail in the above embodiments, and will not be described here.

[0070] In step S320, a measurement of the positioning reference signal PRS is performed based on the target configuration information, and a measurement result is obtained.

[0071] As described above, the target configuration information can include at least one of measurement configuration information of a positioning measurement, reporting configuration information, and configuration information of the positioning reference signal PRS. In some embodiments, after receiving the target configuration information, the terminal device can perform a positioning reference signal PRS-related measurement based on the measurement configuration information of the positioning measurement in the target configuration information to obtain a measurement result. The measurement configuration information of the positioning measurement can include measurement bandwidth, measurement period, and information about where to measure the PRS.

[0072] In the embodiments of the present disclosure, the positioning reference signal PRS measurement can be any one of the following: a reference signal time difference (RSTD) measurement; a reference signal receiving power (RSRP) measurement, where the reference signal receiving power can be a PRS resource reference signal receiving power, i.e., a PRS-RSRP measurement; and a terminal device receive-transmit time difference measurement (UE Rx-Tx time difference). The reference signal time difference measurement, the reference signal receiving power measurement, and the terminal device receive-transmit time difference measurement can all be down link (DL) measurements.

[0073] In step S330, the measurement result and the measurement bandwidth of the positioning reference signal PRS are sent to the network side device.

[0074] In some embodiments, after obtaining the measurement result, the terminal device can send data to the network side device based on the reporting configuration information in the target configuration information, where the reporting configuration information in the target configuration information can include information about which data to report and in which form to report the data. The reported data can include the measurement result and the measurement bandwidth of the positioning reference signal PRS, and whether to report the measurement bandwidth of the positioning reference signal PRS can be determined by the configuration information of the positioning reference signal PRS sent by the network side device.

[0075] As described above, the target configuration information can also include configuration information of the positioning reference signal PRS, which can be used to indicate whether to report the bandwidth of the positioning reference signal PRS. When the configuration information of the positioning reference signal PRS indicates that the bandwidth of the positioning reference signal PRS is to be reported, the terminal device can send the measurement bandwidth of the positioning reference signal PRS to the network side device at the same time as sending the measurement result to the network side device.

[0076] As an example, the target configuration information received by the terminal device can include a parameter reportMeasurementwithBW, which can be included in the IE RequestLocationInformation. When the terminal device determines that the value of the parameter reportMeasurementwithBW in the target configuration information is TRUE, it can send the measurement bandwidth of the PRS to the network side device. At this time, the data sent by the terminal device to the network side device can be the measurement result and the measurement bandwidth of the PRS.

[0077] As another example, when the terminal device determines that the value of the parameter reportMeasurementwithBW in the target configuration information is FALSE, it can not send the measurement bandwidth of the PRS to the network side device. At this time, the terminal device only needs to send the measurement result to the network side device.

[0078] In summary, if the terminal device is required by the network side device to report the measured PRS reference signal bandwidth, it can report the indication information of the measured PRS reference signal bandwidth in the IE ProvideLocationInformation. The reporting requirement can be included in the target configuration information. The reporting requirement here can be the configuration information of the PRS in the above embodiments.

[0079] It should be noted that the reporting of the measurement result is similar to the reporting of the measurement bandwidth of the PRS, and the terminal device can also send the measurement result to the network side device through the IE ProvideLocationInformation.

[0080] It should be noted that the multiple embodiments or features separated by "or" do not affect other solutions even if some features are not achievable. In addition, the embodiments of the present disclosure can be combined with other embodiments or implementation manners and various optional solutions related to the communication method of the terminal device without contradiction, which will not be described here.

[0081] Figure 7 is a communication timing diagram of a communication method according to still other embodiments. As shown in FIG. 8, the terminal device receives the target configuration information from the network side device, and then determines the value of the parameter reportMeasurementwithBW in the target configuration information. When the value of the parameter reportMeasurementwithBW is TRUE, the terminal device sends the measurement bandwidth of the PRS to the network side device. At this time, the data sent by the terminal device to the network side device can be the measurement result and the measurement bandwidth of the PRS. Figure 7As shown, the terminal device can receive target configuration information from the network side device, and based on the target configuration information, the terminal device can perform measurement of the positioning reference signal PRS to obtain measurement results, and then the terminal device can send the measurement results and the measurement bandwidth of the positioning reference signal PRS to the network side device.

[0082] In the embodiments of the present disclosure, the terminal device can send the measurement bandwidth of the positioning reference signal PRS to the network side device, so that the positioning accuracy and positioning performance can be improved, and the problem that different measurement bandwidths correspond to different measurement accuracies can be solved.

[0083] Figure 8 A flowchart of a communication method according to some embodiments is shown. As shown in Figure 8 The communication method can be used in a network side device, and includes the following steps.

[0084] In step S410, the measurement bandwidth of the positioning reference signal PRS is received from the terminal device.

[0085] In the embodiments of the present disclosure, the network side device can receive the measurement bandwidth of the positioning reference signal PRS from the terminal device. Before that, the network side device can send target configuration information to the terminal device, so as to instruct the terminal device to perform measurement of the positioning reference signal PRS based on the target configuration information to obtain measurement results. Here, the target configuration information can include at least one of measurement configuration information of positioning measurement, reporting configuration information, and configuration information of the positioning reference signal PRS.

[0086] In some embodiments, the positioning reference signal PRS measurement includes any one of the following: reference signal time difference measurement; reference signal received power measurement; terminal device receive-transmit time difference measurement.

[0087] It should be noted that the multiple embodiments or features separated by "or" will not affect other solutions even if some of the features are not achievable. In addition, the embodiments of the present disclosure can be combined with other embodiments or embodiments of the terminal device communication method and various optional solutions thereof without contradiction, which will not be described here.

[0088] In the embodiments of the present disclosure, the network side device can receive the measurement bandwidth of the positioning reference signal PRS from the terminal device, so that the positioning accuracy and positioning performance can be improved, and the problem that different measurement bandwidths correspond to different measurement accuracies can be solved.

[0089] Figure 9is a flowchart of a communication method according to some embodiments. As shown in Figure 9 The communication method can be used in a network-side device, including the following steps.

[0090] In step S510, a measurement result and a measurement bandwidth of a positioning reference signal PRS are received from a terminal device.

[0091] In the embodiments of the present disclosure, after sending the target configuration information to the terminal device, the network-side device can receive the measurement result and the measurement bandwidth of the positioning reference signal PRS from the terminal device. The measurement bandwidth of the positioning reference signal PRS is sent to the network-side device by the terminal device based on the target configuration information when the terminal device determines that it needs to be reported.

[0092] In addition, the network-side device can receive the measurement result and the measurement bandwidth of the positioning reference signal PRS at the same time, or can receive the measurement result first and then receive the measurement bandwidth of the positioning reference signal PRS, or can receive the measurement bandwidth of the positioning reference signal PRS first and then receive the measurement result. The specific order of receiving the data is not limited here and can be selected according to the actual situation.

[0093] In step S520, a measurement accuracy requirement corresponding to the measurement bandwidth of the positioning reference signal PRS is determined.

[0094] As an optional way, after receiving the measurement bandwidth of the positioning reference signal PRS sent by the terminal device, the network-side device can determine the measurement accuracy requirement corresponding to the measurement bandwidth of the positioning reference signal PRS. The measurement accuracy requirement corresponding to the measurement bandwidth of the positioning reference signal PRS may not be the same when the measurement bandwidth of the positioning reference signal PRS is different.

[0095] As a specific implementation, in a case where it is determined that the measurement bandwidth BW1 of the positioning reference signal PRS received from the terminal device is greater than or equal to A and less than or equal to B, i.e., A≤BW1≤B, it is determined that the measurement accuracy requirement corresponding to the measurement bandwidth BW1 of the positioning reference signal PRS is a first set of PRS measurement accuracy requirements.

[0096] As another specific implementation, in a case where it is determined that the measurement bandwidth BW2 of the positioning reference signal PRS received from the terminal device is greater than or equal to B and less than or equal to C, i.e., B≤BW2≤C, it is determined that the measurement accuracy requirement corresponding to the measurement bandwidth BW2 of the positioning reference signal PRS is a second set of PRS measurement accuracy requirements.

[0097] As another specific implementation, in a case where it is determined that the measurement bandwidth BW3 of the positioning reference signal PRS received at the terminal device is greater than or equal to C and less than or equal to D, i.e., C≤BW3≤D, it is determined that the measurement accuracy requirement corresponding to the measurement bandwidth BW3 of the positioning reference signal PRS is the third set of PRS measurement accuracy requirements.

[0098] Here, the accuracy requirement ranges of the first set of PRS measurement accuracy requirements, the second set of PRS measurement accuracy requirements, and the third set of PRS measurement accuracy requirements are different. For example, the range of the first set of PRS measurement accuracy requirements is plus or minus 2. For another example, the range of the second set of PRS measurement accuracy requirements is plus or minus 1. The accuracy requirement ranges of the first set of PRS measurement accuracy requirements, the second set of PRS measurement accuracy requirements, and the third set of PRS measurement accuracy requirements are not specifically limited here, and can be selected according to actual conditions.

[0099] It should be noted that the parameters of the first set of PRS measurement accuracy requirements, the second set of PRS measurement accuracy requirements, and the third set of PRS measurement accuracy requirements are the same. For example, the parameters of the first set of PRS measurement accuracy requirements, the second set of PRS measurement accuracy requirements, and the third set of PRS measurement accuracy requirements are all RSTD.

[0100] In step S530, the position information of the terminal device is obtained based on the measurement accuracy requirement and the measurement result.

[0101] In some embodiments, after obtaining the measurement accuracy requirement corresponding to the bandwidth of the positioning reference signal PRS, the position information of the terminal device can be determined based on the measurement accuracy requirement and the measurement result. Different measurement accuracy requirements correspond to different final obtained position information of the terminal device.

[0102] In the embodiments of the present disclosure, the measurement accuracy requirement can include any one of the following: a reference signal time difference (RSTD) measurement accuracy requirement; a reference signal received power (RSRP) measurement accuracy requirement, which can be a PRS resource reference signal received power measurement accuracy requirement, i.e., a PRS-RSRP measurement accuracy requirement; and a terminal device receive-transmit time difference measurement accuracy requirement (UE Rx-Tx time difference).

[0103] It should be noted that the different accuracy requirements defined according to different bandwidths described above can be written in the protocol in advance, i.e., different accuracy requirements can be defined according to the configuration.

[0104] It should also be noted that the use of the "or" in the examples or features that are connected with "or" does not mean that some features are not applicable. In addition, the embodiments of the present disclosure can be combined with other embodiments of the communication method for the terminal device and various optional schemes thereof without contradiction, which will not be described here.

[0105] The embodiments of the present disclosure provide that the network side device can receive the measurement bandwidth of the positioning reference signal PRS from the terminal device, so as to improve the positioning accuracy and positioning performance, thereby solving the problem that different measurement bandwidths correspond to different measurement accuracies. In addition, the embodiments of the present disclosure obtain the position information of the terminal device by combining the measurement accuracy requirement and the measurement result, which can ensure the accuracy of the position information acquisition.

[0106] Figure 10 A flowchart of a communication method according to still other embodiments is shown. As shown in Figure 10 The communication method can be used in a network side device, including the following steps.

[0107] In step S610, the measurement result and the measurement bandwidth of the positioning reference signal PRS are received from the terminal device.

[0108] In step S620, the measurement accuracy requirement corresponding to the measurement bandwidth of the positioning reference signal PRS is determined.

[0109] The specific embodiments of steps S610 to S620 have been described in detail in the above embodiments, which will not be described here.

[0110] In step S630, the measurement result is evaluated according to the measurement accuracy requirement, and a measurement evaluation result is obtained.

[0111] As an optional way, after obtaining the measurement accuracy requirement corresponding to the measurement bandwidth of the positioning reference signal PRS, the network side device can also evaluate the measurement result sent by the terminal device according to the accuracy requirement, and obtain a measurement evaluation result.

[0112] As an example, the network side device configures 5M PRS for the terminal device. After the terminal device measures the 5M PRS, it will send the 5M measurement result and the measurement bandwidth to the network side device. The network side device can obtain the accuracy requirement corresponding to 5M, and then evaluate the measurement result sent by the terminal device in the process of evaluating the measurement result. The network side device can use the accuracy requirement of 5M to evaluate whether the measurement result sent by the terminal device is accurate or not.

[0113] As another example, the network-side device configures the terminal device with a PRS of 10M. After the terminal device measures the PRS of 10M, the terminal device sends the network-side device with the measurement result of 10M and the measurement bandwidth. The network-side device can obtain the accuracy requirement corresponding to the 10M, and then in the process of evaluating the measurement result, the network-side device can use the accuracy requirement of 10M to evaluate whether the measurement result sent by the terminal device is accurate or not.

[0114] It should be noted that the use of "or" to separate a plurality of embodiments or features, even if some of the features are not realized, will not affect other solutions. In addition, the embodiments of the present disclosure can be combined with other embodiments or implementation manners and various optional solutions involved in other communication methods for terminal devices without contradiction, which will not be repeated here.

[0115] The embodiments of the present disclosure provide that the network-side device can receive the measurement bandwidth of the positioning reference signal PRS from the terminal device, which can improve the positioning accuracy and positioning performance, and thus can solve the problem of different measurement bandwidths corresponding to different measurement accuracies. In addition, the network-side device can use the measurement accuracy requirement obtained by it to evaluate the measurement result uploaded by the terminal device to obtain a measurement evaluation result, which can improve the accuracy of positioning.

[0116] Figure 11 is a flowchart of a communication method according to still other embodiments. As shown in Figure 11 , the communication method can be used in a network-side device, including the following steps.

[0117] In step S710, the measurement result and the measurement bandwidth of the positioning reference signal PRS are received from the terminal device.

[0118] In step S720, the measurement accuracy requirement corresponding to the measurement bandwidth of the positioning reference signal PRS is determined.

[0119] In step S730, the measurement result is evaluated according to the measurement accuracy requirement to obtain a measurement evaluation result.

[0120] The specific implementation of steps S710 to S740 can refer to the introduction of the above embodiments, which will not be repeated here.
