[0053] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0054] To facilitate understanding, the terms involved in this disclosure are first introduced.

[0055] 1. Global Navigation Satellite System (GNSS)

[0056] The Global Navigation Satellite System (GNSS) refers to all satellite navigation systems, including global, regional and enhanced ones, such as the United States' GPS, Russia's Glonass, Europe's Galileo, China's BeiDou Navigation Satellite System, and related augmentation systems, such as the United States' WAAS (Wide Area Augmentation System), Europe's EGNOS (European Geostationary Navigation Overlay System) and Japan's MSAS (Multi-functional Transport Satellite Augmentation System). It also covers other satellite navigation systems under construction or to be built in the future.

[0057] 2. Timing Advance (TA)

[0058] Signal transmission in space is subject to delay. If a terminal device moves away from the base station during a call, the signal from the base station will arrive at the terminal device increasingly late. Simultaneously, the terminal device's signal will also arrive at the base station increasingly late. Excessive delay can cause the signal from a terminal device received by the base station in its current timeslot to overlap with the next timeslot in which the base station receives a signal from another terminal device, causing inter-symbol interference (ISI). Therefore, during data transmission, the terminal device's uplink transmission must be advanced by a certain amount to ensure that the time interval between different users' uplink transmissions arriving at the base station is within a predefined threshold. The base station can send a timing advance command on the downlink channel to the terminal device, instructing it to advance its transmission time. This time is called the timing advance.

[0059] See Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure. The communication system may include but is not limited to a network device and a terminal device. Figure 1 The number and form of devices shown are for example only and do not constitute a limitation on the embodiments of the present disclosure. In actual applications, two or more network devices and two or more terminal devices may be included. Figure 1 The communication system shown includes a network device 11, a terminal device 12 and a satellite 13 as an example.

[0060] It should be noted that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as long-term evolution (LTE) systems, fifth-generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems.

[0061] The network device 11 in the embodiment of the present disclosure is an entity on the network side for transmitting or receiving signals. For example, the network device 11 can be an evolved NodeB (eNB), a transmission point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiment of the present disclosure does not limit the specific technology and specific device form adopted by the network device. The network device provided in the embodiment of the present disclosure can be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU can also be called a control unit.

[0062] The terminal device 12 in the embodiment of the present disclosure is an entity on the user side for receiving or transmitting signals, such as a mobile phone.

[0063] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0064] Typically, when a terminal device reports location information obtained based on GNSS measurements to a network device, the network device may deem the location information unreliable. To avoid conflicts between the time-frequency domain resources configured for the terminal device based on the location information and other terminal devices, the network device may instruct the terminal device to report a timing advance (TA) when the location information is unreliable, thereby verifying the location information reported by the terminal device based on the TA reported by the terminal device. A method for determining location information and an apparatus thereof provided by the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0065] See Figure 2 , Figure 2 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a network device. Figure 2 As shown, the method may include but is not limited to the following steps:

[0066] Step 201: Receive location information sent by a first terminal device, wherein the location information is determined by the first terminal device by measuring signals from multiple satellites.

[0067] Among them, the location information can be the location information determined by the terminal device, or it can be any information that can characterize the location of the terminal device, for example, it can be the measurement result of the satellite signal measured by the terminal device, so that the network device can determine the specific location of the terminal device by analyzing the measurement result.

[0068] Optionally, the location information may include any of the following: location coordinate information of the terminal device, measurement results of signals of multiple satellites and information of multiple satellites, etc. This disclosure does not impose any limitation on this.

[0069] In the present disclosure, after measuring signals from multiple satellites, a terminal device can determine the number of measurement results to report based on the measurement results for each satellite, or alternatively, based on instructions from a network device. Therefore, the number of satellite signal measurement results reported can be smaller than the number of satellite signals measured by the terminal device. Thus, by reporting measurement results for a subset of satellite signals and satellite information, the terminal device's location can be determined, reducing the transmission of redundant data and thus avoiding waste of resources.

[0070] In the present disclosure, a terminal device can determine its location information by measuring signals from multiple satellites, and then send the determined location information to a network device. The network device can then determine the reliability of the terminal device's location information and, if the terminal device's location information is reliable, perform resource scheduling.

[0071] Step 202: trigger the first terminal device to perform timed advance TA reporting.

[0072] Optionally, the network device may trigger the first terminal device to perform timed advance TA reporting when it is determined that the location information reported by the terminal device meets a preset condition.

[0073] In the present disclosure, the location information reported by the terminal device may contain errors or be tampered with. Therefore, the network device can trigger the first terminal device to perform TA reporting when it determines that the location information reported by the first terminal device meets the preset conditions, so as to verify the reliability of the reported location information and ensure the accuracy of the location information.

[0074] Optionally, the preset condition may be agreed upon in the protocol or pre-configured, and this disclosure does not limit this.

[0075] Optionally, the network device may determine that the location information reported by the first terminal device meets a preset condition when the success rate of the uplink transmission corresponding to the first terminal device is less than a first threshold.

[0076] In the present disclosure, after a network device schedules resources based on the location information reported by a terminal device, if the location information reported by the terminal device is inaccurate, uplink transmission may be disrupted when the terminal device transmits data using resources allocated based on that location information, resulting in a failure in the network device's demodulation of the data sent by the terminal device, i.e., an uplink data transmission failure. Therefore, the network device can determine whether the location information reported by the terminal device meets preset conditions based on the success rate of the terminal device's uplink transmission.

[0077] When the uplink transmission success rate is high, the reliability of the corresponding location information can be determined to be high. When the uplink transmission success rate is low, the reliability of the corresponding location information can be determined to be low. The first threshold may be agreed upon in a protocol or may be pre-set in the system, and this disclosure does not limit this.

[0078] In the present disclosure, the network device may trigger the first terminal device to perform timing advance TA reporting by sending a trigger instruction. Alternatively, the network device may instruct the first terminal device to perform timing advance TA reporting by instructing the trigger through a radio resource control (RRC) message, a media access control (MAC) control element (CE), physical layer signaling, etc.

[0079] For example, the value of any bit in the physical layer signaling can be used to indicate that the first terminal device is triggered to perform timing advance TA reporting. Therefore, after receiving the physical layer signaling, the terminal device can determine whether to perform timing advance TA reporting based on the value of this bit.

[0080] Alternatively, the network device may also instruct the first terminal device to trigger the timing advance TA reporting in a configurable information field in the physical layer signaling.

[0081] In the present disclosure, after receiving the location information sent by the first terminal device and determined by measuring the signals of multiple satellites, the network device triggers the first terminal device to perform timed advance TA reporting to verify the location information reported by the first terminal device, thereby avoiding resource scheduling conflicts and ensuring the reliability of communication.

[0082] See Figure 3 , Figure 3 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a network device. Figure 3 As shown, the method may include but is not limited to the following steps:

[0083] Step 301: Send second indication information to a first terminal device, where the second indication information is used to indicate information of multiple satellites.

[0084] In the present disclosure, a network device can determine the satellite information that each terminal can use for positioning based on the information of each satellite, and then indicate the satellite information that each terminal can use for positioning to the corresponding terminal device. The satellite information can be any information that can uniquely identify a satellite, such as a satellite number, and this disclosure is not limited to this.

[0085] Step 302: Receive location information sent by the first terminal device, wherein the location information is determined by the first terminal device by measuring signals from multiple satellites.

[0086] Step 303: When it is determined that the location information sent by the first terminal device meets the preset conditions, the first terminal device is triggered to perform timed advance TA reporting.

[0087] In the present disclosure, the specific implementation process of step 302-step 303 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.

[0088] In the present disclosure, after the network device sends the second indication information for indicating information of multiple satellites to the first terminal device, it can receive the location information sent by the first terminal device that is determined by measuring the signals of multiple satellites. Thereafter, when it is determined that the location information sent by the first terminal device meets the preset conditions, the first terminal device can be triggered to perform a timed advance TA report to verify the location information reported by the first terminal device, thereby avoiding resource scheduling conflicts and ensuring the reliability of communication.

[0089] See Figure 4 , Figure 4 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a network device. Figure 4 As shown, the method may include but is not limited to the following steps:

[0090] Step 401: Receive first indication information sent by a first terminal device, where the first indication information is used to indicate information of multiple satellites.

[0091] In the present disclosure, after the terminal device obtains the ephemeris information of multiple satellites, it can determine the multiple satellites used to obtain position information based on the ephemeris information of each satellite, and send the information of the multiple satellites to the network device.

[0092] Step 402: Determine multiple satellites.

[0093] In the present disclosure, after receiving the first indication information sent by the terminal device, the network device can determine the information of multiple satellites used to obtain location information based on the first indication information. Thus, the network device can determine whether the location information is reliable based on the satellite information and the measurement results of the signal of each satellite reported by the terminal device.

[0094] Step 403: Receive location information sent by the first terminal device, wherein the location information is determined by the first terminal device by measuring signals from multiple satellites.

[0095] Step 404: When it is determined that the location information sent by the first terminal device meets the preset conditions, the first terminal device is triggered to perform timed advance TA reporting.

[0096] In the present disclosure, the specific implementation process of step 403-step 404 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.

[0097] In the present disclosure, after the network device receives the first indication information sent by the first terminal device for indicating information of multiple satellites, it can determine the multiple satellites. Thereafter, it can receive the position information sent by the first terminal device that is determined by measuring the signals of multiple satellites. Then, when it is determined that the position information sent by the first terminal device meets the preset conditions, it can trigger the first terminal device to perform a timed advance TA report to verify the position information reported by the first terminal device, thereby avoiding resource scheduling conflicts and ensuring the reliability of communication.

[0098] See Figure 5 , Figure 5 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a network device. Figure 5 As shown, the method may include but is not limited to the following steps:

[0099] Step 501: Send second indication information to a first terminal device, where the second indication information is used to indicate information of multiple satellites.

[0100] In the present disclosure, the specific implementation process of step 501 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.

[0101] Step 502: Send third indication information to the first terminal device, where the third indication information is used to indicate measurement configuration information of each satellite.

[0102] The measurement configuration information may include at least one of the following: a measurement time window and pilot information, which is not limited in the present disclosure.

[0103] In addition, the measurement configuration information can be used to instruct the terminal device how to perform position measurement, and the pilot information can be a sequence value of the pilot, etc., which is not limited in this disclosure.

[0104] In this disclosure, a network device can directly send measurement configuration information for each satellite to a terminal device. The terminal device can then determine the target signals for position measurement based on the pilot information. The terminal device can then measure the target signals within a measurement time window to determine the terminal device's location.

[0105] Optionally, the network device may configure the third indication information in system information, or radio resource control (RRC) signaling, or media access control sublayer information (MAC CE), or physical layer signaling. Thus, the network device can send the third indication information to the first terminal device through system information, or RRC signaling, or MAC CE, or physical layer signaling.

[0106] Step 503: Receive location information sent by the first terminal device, wherein the location information is determined by the first terminal device by measuring signals from multiple satellites.

[0107] Step 504: When it is determined that the location information sent by the first terminal device meets the preset conditions, the first terminal device is triggered to perform timed advance TA reporting.

[0108] In the present disclosure, the specific implementation process of step 503-step 504 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.

[0109] In the present disclosure, the network device can send second indication information for indicating information of multiple satellites and third indication information for indicating measurement configuration information of each satellite to the first terminal device. After that, the network device can receive the position information sent by the first terminal device determined by measuring the signals of multiple satellites. Then, when it is determined that the position information sent by the first terminal device meets the preset conditions, the first terminal device can be triggered to perform timed advance TA reporting to verify the position information reported by the first terminal device, thereby avoiding resource scheduling conflicts and ensuring the reliability of communication.

[0110] See Figure 6 , Figure 6 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a network device. Figure 6 As shown, the method may include but is not limited to the following steps:

[0111] Step 601: Receive location information sent by a first terminal device, wherein the location information is determined by the first terminal device by measuring signals from multiple satellites.

[0112] Step 602: When the success rate of uplink transmission corresponding to the second terminal device associated with the first terminal device is less than a second threshold, determine that the location information reported by the first terminal device meets a preset condition.

[0113] In the present disclosure, any terminal device can be determined to be a second terminal device in response to the distance between the location information reported by any terminal device and the location information reported by the first terminal device being less than a third threshold and the confidence level of the location information reported by any terminal device being greater than a fourth threshold.

[0114] The third threshold and the fourth threshold may be agreed upon in a protocol or pre-configured, and this disclosure does not limit this.

[0115] Optionally, in response to the interval between the scheduling resources corresponding to any terminal device and the scheduling resources corresponding to the first terminal device being less than the fifth threshold and the confidence level of the location information reported by any terminal device being greater than the fourth threshold, any terminal device is determined to be a second terminal device.

[0116] The scheduling resources may be time-frequency resources, etc. The fifth threshold may be agreed upon in a protocol, or may be pre-configured, and this disclosure does not limit this.

[0117] In the present disclosure, after the network device schedules resources for the second terminal device, when the second terminal device transmits data based on the allocated resources, the network device has a high probability of failure when demodulating the data sent by the second terminal device, and the location information reported by the second terminal is reliable. In this case, it may be due to the inaccurate location information of the first terminal device, which causes the network device to believe that the location interval between the first terminal device and the second terminal device is relatively small, so that the scheduling resource interval allocated to the first terminal device and the second terminal device is relatively small, that is, there is a conflict in the scheduling resources allocated to the first terminal device and the second terminal device, which causes the second terminal device to fail to upload data. Therefore, the reliability of the location information reported by the first terminal device can be determined based on the success rate of the uplink transmission corresponding to the second terminal device. When the uplink transmission success rate is low, it can be determined that the reliability of the location information corresponding to the first terminal device is low.

[0118] Step 603: When it is determined that the location information sent by the first terminal device meets the preset conditions, the first terminal device is triggered to perform timing advance TA reporting.

[0119] In the present disclosure, the specific implementation process of step 603 can be found in the detailed description of any embodiment of the present disclosure, and will not be repeated here.

[0120] In the present disclosure, a network device may determine that the location information reported by a first terminal device satisfies a preset condition when the success rate of uplink transmissions corresponding to a second terminal device associated with the first terminal device is less than a second threshold. Subsequently, upon determining that the location information sent by the first terminal device satisfies the preset condition, the network device may trigger the first terminal device to report a timing advance (TA) to verify the location information reported by the first terminal device, thereby avoiding resource scheduling conflicts and ensuring communication reliability.

[0121] See Figure 7 , Figure 7 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a network device. Figure 7 As shown, the method may include but is not limited to the following steps:

[0122] Step 701: Send a fourth indication message to the first terminal device, wherein the fourth indication message is used to indicate the configuration information measured by the TA and / or the configuration information reported by the TA to the first terminal device.

[0123] The configuration information measured by the TA may include: an identifier of the measurement configuration information, a measurement target, and information about the time when the measurement is performed, etc. The configuration information reported by the TA may include: an identifier of the reported configuration information, and information about the time when the report is made, etc. This disclosure does not limit this.

[0124] In the present disclosure, TA measurement configuration information can be used to instruct a terminal device to perform TA measurement to determine the delay from the terminal device to the network device. TA reporting configuration information can be used to instruct a terminal device on how to perform TA reporting. The identifier of the measurement configuration information can be any information that can uniquely identify the measurement configuration, such as the measurement configuration information number. The measurement target can be a measurement signal assigned by the network device to the terminal device. The identifier of the reporting configuration information can be any information that can uniquely identify the reporting configuration, such as the reporting configuration number.

[0125] In the present disclosure, the network device can directly send the TA measurement configuration information or the TA reporting configuration information to the terminal device. Alternatively, when the network device has sent multiple TA measurement configuration information to the terminal device, the network device can send the identification of the measurement configuration information to the terminal device. After receiving the TA measurement configuration information sent by the network device, the terminal device can determine the TA measurement-related configuration according to the identification of the reporting configuration information, and then perform TA measurement according to the measurement configuration. When the network device has sent multiple TA reporting configuration information to the terminal device, the network device can send the identification of the reporting configuration information to the terminal device. The terminal device can determine the reporting-related configuration according to the identification of the reporting configuration information, and then perform TA reporting according to the reported time information.

[0126] Optionally, the network device may configure the fourth indication information in system information, or radio resource control (RRC) signaling, or media access control sublayer information (MAC CE), or physical layer signaling. This disclosure does not impose any restrictions on this.

[0127] Step 702: Receive location information sent by the first terminal device, where the location information is determined by the first terminal device by measuring signals from multiple satellites.

[0128] Step 703: When it is determined that the location information sent by the first terminal device meets the preset conditions, the first terminal device is triggered to perform timed advance TA reporting.

[0129] In the present disclosure, the specific implementation process of step 702-step 703 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.

[0130] It should be noted that the present disclosure does not limit the execution order of step 702 and step 701, that is, step 702 and step 701 can be executed simultaneously, or step 702 can be executed first and then step 701. The present disclosure does not limit this.

[0131] In the present disclosure, after the network device sends a fourth indication message to the first terminal device for indicating the configuration information of TA measurement and / or the configuration information reported by TA to the first terminal device, it can receive the location information sent by the first terminal device that is determined by measuring the signals of multiple satellites. Thereafter, when it is determined that the location information sent by the first terminal device meets the preset conditions, the first terminal device can be triggered to perform timed advance TA reporting to verify the location information reported by the first terminal device, thereby avoiding resource scheduling conflicts and ensuring the reliability of communication.

[0132] See Figure 8 , Figure 8 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a network device. Figure 8 As shown, the method may include but is not limited to the following steps:

[0133] Step 801: Receive location information sent by a first terminal device, wherein the location information is determined by the first terminal device by measuring signals from multiple satellites.

[0134] Step 802: When it is determined that the location information sent by the first terminal device meets the preset conditions, the first terminal device is triggered to perform timed advance TA reporting.

[0135] In the present disclosure, the specific implementation process of step 801-step 802 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.

[0136] Step 803: Receive the TA reported by the first terminal device.

[0137] In the present disclosure, after receiving the trigger TA reporting instruction sent by the network device, the first terminal device can report the TA information to the network device. Alternatively, the first terminal device can also trigger and start the timing advance TA reporting autonomously.

[0138] Step 804: Determine the credibility of the location information reported by the first terminal device based on the TA.

[0139] Step 805: When the credibility is less than the sixth threshold, fifth indication information is sent to the first terminal device, wherein the fifth indication information is used to instruct the first terminal to release the wireless link connection or re-report the location information.

[0140] The sixth threshold may be agreed upon in a protocol or pre-configured, and this disclosure does not limit this.

[0141] In the present disclosure, any bit in the sending instruction can be used to identify the fifth indication information. For example, if the fifth indication information is used to instruct the first terminal to release the wireless link connection, this bit can be set to 0; if the fifth indication information is used to instruct the first terminal to re-report location information, this bit can be set to 1.

[0142] In the present disclosure, after receiving the location information sent by the first terminal device and determined by measuring the signals of multiple satellites, and triggering the first terminal device to perform timed advance TA reporting when determining that the location information sent by the first terminal device meets the preset conditions, the network device can receive the TA reported by the first terminal device, and then determine the credibility of the location information reported by the first terminal device based on the TA. Then, when the credibility is less than the sixth threshold, the network device can send to the first terminal device fifth indication information for instructing the first terminal to release the wireless link connection or re-report the location information. In this way, the reliability of the terminal device location information can be improved, thereby avoiding resource scheduling conflicts and ensuring the reliability of communication.

[0143] See Figure 9 , Figure 9 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 9 As shown, the method may include but is not limited to the following steps:

[0144] Step 901: Send location information of a terminal device to a network device, wherein the location information is determined by the terminal device by measuring signals from multiple satellites.

[0145] Among them, the location information can be the location information determined by the terminal device, or it can be any information that can characterize the location of the terminal device, for example, it can be the measurement result of the satellite signal measured by the terminal device, so that the network device can determine the specific location of the terminal device by analyzing the measurement result.

[0146] Optionally, the location information may include any of the following: location coordinate information of the terminal device, measurement results of signals of multiple satellites and information of multiple satellites, etc. This disclosure does not impose any limitation on this.

[0147] In the present disclosure, after measuring signals from multiple satellites, a terminal device can determine the number of measurement results to report based on the measurement results for each satellite, or alternatively, based on instructions from a network device. Therefore, the number of satellite signal measurement results reported can be smaller than the number of satellite signals measured by the terminal device. Thus, by reporting measurement results for a subset of satellite signals and satellite information, the terminal device's location can be determined, reducing the transmission of redundant data and thus avoiding waste of resources.

[0148] In the present disclosure, a terminal device can determine its location information by measuring signals from multiple satellites, and then send the determined location information to a network device. The network device can then determine the reliability of the terminal device's location information and, if the terminal device's location information is reliable, perform resource scheduling.

[0149] Step 902: Execute timing advance TA reporting.

[0150] In the present disclosure, the location information reported by the terminal device may contain errors or be tampered with. Therefore, the terminal device can report the TA, and the network device can verify the reliability of the reported location information based on the reported TA to ensure the accuracy of the location information.

[0151] Optionally, the terminal device may trigger TA reporting when it determines that the location information meets preset conditions.

[0152] The preset conditions may be agreed upon in the protocol or pre-configured, and this disclosure does not limit this.

[0153] Optionally, the terminal device may trigger TA reporting based on instructions from the network device.

[0154] In the present disclosure, the network device may trigger the terminal device to perform timed advance TA reporting if it determines that the location information reported by the terminal device meets a preset condition. The preset condition may be a protocol agreement or pre-configured, which is not limited in the present disclosure.

[0155] Optionally, the network device may determine that the location information reported by the terminal device meets a preset condition when the success rate of the uplink transmission corresponding to the terminal device is less than a first threshold.

[0156] In the present disclosure, after a network device schedules resources based on the location information reported by a terminal device, if the location information reported by the terminal device is inaccurate, uplink transmission may be disrupted when the terminal device transmits data using resources allocated based on that location information, resulting in a failure in the network device's demodulation of the data sent by the terminal device, i.e., an uplink data transmission failure. Therefore, the network device can determine whether the location information reported by the terminal device meets preset conditions based on the success rate of the terminal device's uplink transmission.

[0157] When the uplink transmission success rate is high, the reliability of the corresponding location information can be determined to be high. When the uplink transmission success rate is low, the reliability of the corresponding location information can be determined to be low. The first threshold may be agreed upon in a protocol or may be pre-set in the system, and this disclosure does not limit this.

[0158] In the present disclosure, the network device may trigger the terminal device to perform timing advance reporting by sending a trigger instruction. Alternatively, the network device may instruct the terminal device to perform timing advance reporting by instructing the terminal device to perform timing advance reporting through a radio resource control (RRC) message, a media access control (MAC) control element (CE), physical layer signaling, etc.

[0159] For example, the value of any bit in the physical layer signaling can be used to instruct the terminal device to trigger the execution of timing advance TA reporting. Therefore, after receiving the physical layer signaling, the terminal device can determine whether to execute timing advance TA reporting based on the value of this bit.

[0160] Alternatively, the network device may also instruct the terminal device to trigger the reporting of the timing advance TA in a configurable information field in the physical layer signaling.

[0161] In the present disclosure, after the terminal device sends the location information determined by measuring the signals of multiple satellites to the network device, the terminal device can perform a timing advance TA report. As a result, the network device can verify the location information reported by the terminal device based on the reported timing advance TA, thereby avoiding resource scheduling conflicts and ensuring the reliability of communication.

[0162] See Figure 10 , Figure 10 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 10 As shown, the method may include but is not limited to the following steps:

[0163] Step 1001: Receive second indication information sent by a network device, where the second indication information is used to indicate information of multiple satellites.

[0164] In the present disclosure, a network device can determine the satellite information that each terminal can use for positioning based on the information of each satellite, and then indicate the satellite information that each terminal can use for positioning to the corresponding terminal device. The satellite information can be any information that can uniquely identify a satellite, such as a satellite number, and this disclosure is not limited to this.

[0165] Step 1002: Send location information of the terminal device to the network device, wherein the location information is determined by the terminal device by measuring signals from multiple satellites.

[0166] Step 1003: When it is determined that the location information meets the preset conditions, the TA reporting is performed in advance.

[0167] In the present disclosure, the specific implementation process of step 1002-step 1003 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.

[0168] In the present disclosure, a terminal device may send first indication information indicating information about multiple satellites to a network device. Subsequently, the terminal device may send location information determined by measuring signals from multiple satellites to the network device. If the location information satisfies a preset condition, the network device may report a timing advance (TA). The network device can then verify the location information reported by the terminal device based on the reported timing advance (TA), thereby avoiding resource scheduling conflicts and ensuring communication reliability.

[0169] See Figure 11 , Figure 11 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 11 As shown, the method may include but is not limited to the following steps:

[0170] Step 1101: Send first indication information to a network device, where the first indication information is used to indicate information of multiple satellites.

[0171] In this disclosure, after obtaining ephemeris information for multiple satellites, a terminal device can determine the multiple satellites used to obtain location information based on the ephemeris information of each satellite and send the information about the multiple satellites to a network device. The network device can then determine whether the location information is reliable based on the satellite information and the measurement results of each satellite's signal reported by the terminal device.

[0172] Step 1102: Send location information of the terminal device to the network device, where the location information is determined by the terminal device by measuring signals from multiple satellites.

[0173] Step 1103: When it is determined that the location information meets the preset conditions, the TA reporting is performed in advance.

[0174] In the present disclosure, the specific implementation process of step 1102-step 1103 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.

[0175] In the present disclosure, a terminal device can send first indication information indicating information about multiple satellites to a network device. Subsequently, the terminal device can send location information determined by measuring signals from multiple satellites to the network device. If the location information satisfies a preset condition, the network device can report a timing advance (TA). The network device can then verify the location information reported by the terminal device based on the reported timing advance (TA), thereby avoiding resource scheduling conflicts and ensuring communication reliability.

[0176] See Figure 12 , Figure 12 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 12 As shown, the method may include but is not limited to the following steps:

[0177] Step 1201: Receive second indication information sent by a network device, where the second indication information is used to indicate information of multiple satellites.

[0178] Step 1202: Receive third indication information sent by the network device, where the third indication information is used to indicate measurement configuration information of each satellite.

[0179] The measurement configuration information may include at least one of the following: a measurement time window and pilot information, which is not limited in the present disclosure.

[0180] In addition, the measurement configuration information can be used to instruct the terminal device how to perform position measurement, and the pilot information can be a sequence value of the pilot, etc., which is not limited in this disclosure.

[0181] In this disclosure, a network device can directly send measurement configuration information for each satellite to a terminal device. The terminal device can then determine the target signals for position measurement based on the pilot information. The terminal device can then measure the target signals within a measurement time window to determine the terminal device's location.

[0182] In the present disclosure, the network device may configure the third indication information in system information, or radio resource control (RRC) signaling, or media access control sublayer information (MAC CE), or physical layer signaling. Thus, the network device can send the third indication information to the terminal device through system information, or RRC signaling, or MAC CE, or physical layer signaling.

[0183] Optionally, the terminal device can receive the third indication information sent by the network device through system information, RRC message, MAC CE, and physical layer signaling.

[0184] Step 1203: Send the location information of the terminal device to the network device, wherein the location information is determined by the terminal device by measuring signals from multiple satellites.

[0185] Step 1204: When it is determined that the location information meets the preset conditions, the TA reporting is performed in advance.

[0186] In the present disclosure, the specific implementation process of step 1203-step 1204 can be found in the detailed description of any embodiment of the present disclosure, and will not be repeated here.

[0187] In the present disclosure, a terminal device can receive second indication information indicating information about multiple satellites and third indication information indicating measurement configuration information for each satellite, sent by a network device. The terminal device can then send location information determined by measuring signals from multiple satellites to the network device. If the location information satisfies a preset condition, the network device can then report a timing advance (TA). This allows the network device to verify the location information reported by the terminal device based on the reported timing advance (TA), thereby avoiding resource scheduling conflicts and ensuring communication reliability.

[0188] See Figure 13 , Figure 13 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 13 As shown, the method may include but is not limited to the following steps:

[0189] Step 1301: Send location information of a terminal device to a network device, wherein the location information is determined by the terminal device by measuring signals from multiple satellites.

[0190] In the present disclosure, the specific implementation process of step 1301 can be found in the detailed description of any embodiment of the present disclosure and will not be repeated here.

[0191] Step 1302: In response to not receiving a hybrid automatic repeat request (HARQ) feedback for a preset number of uplink transmissions, determining that the location information of the terminal device meets a preset condition.

[0192] In the present disclosure, if decoding fails, a terminal device can save the received data and request the network device to retransmit the data. The network device then combines the retransmitted data with the previously received data before decoding. If a terminal device fails to receive HARQ feedback information from the network device, this indicates an uplink transmission error, which may be caused by unreliable terminal location information. Therefore, the terminal device can count the number of times uplink transmissions fail to receive feedback. If a preset number is reached, the terminal device can determine that its location information meets a preset condition.

[0193] Optionally, the terminal device may also determine that the location information of the terminal device meets a preset condition in response to a proportion of negative acknowledgement (NACK) messages received in the HARQ being greater than a first threshold value.

[0194] A non-acknowledgement message indicates that the device cannot understand a message or cannot implement a requested operation. The terminal device may count the proportion of NACKs in received HARQ messages. When the proportion is greater than a first threshold, the terminal device may determine that the location information of the terminal device meets a preset condition. The first threshold may be agreed upon in a protocol or pre-configured, and this disclosure does not limit this.

[0195] Optionally, the terminal device may also determine that the location information of the terminal device meets a preset condition in response to not receiving HARQ feedback for uplink transmission within a preset time period.

[0196] In the present disclosure, a terminal device may determine a preset period based on an uplink transmission delay. For example, the uplink transmission delay may be set to a preset period, or the preset period may be set to be greater than the uplink transmission delay. The terminal device may start timing when sending HARQ information. If the timing reaches the preset period and no HARQ feedback information is received, the terminal device may determine that its location information meets a preset condition.

[0197] Optionally, the terminal device may also determine that the location information of the terminal device meets a preset condition in response to a proportion of non-acknowledgement messages NACK in HARQ received within a preset time period being greater than a second threshold value.

[0198] The second threshold value may be agreed upon in a protocol or pre-configured, which is not limited in the present disclosure.

[0199] Step 1303: When it is determined that the location information meets the preset conditions, TA reporting is triggered.

[0200] In the present disclosure, the specific implementation process of step 1303 can be found in the detailed description of any embodiment of the present disclosure, and will not be repeated here. In the present disclosure, after the terminal device sends the location information determined by the terminal device by measuring the signals of multiple satellites to the network device, it can determine that the location information of the terminal device meets the preset conditions when no HARQ feedback is received after a preset number of uplink transmissions, and trigger the execution of TA reporting when it is determined that the location information meets the preset conditions. In this way, the network device can verify the location information reported by the terminal device according to the reported timing advance TA, thereby avoiding resource scheduling conflicts and ensuring the reliability of communication.

[0201] See Figure 14 , Figure 14 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 14 As shown, the method may include but is not limited to the following steps:

[0202] Step 1401: Receive a fourth indication message sent by a network device, where the fourth indication message is used to indicate configuration information measured by a TA and / or configuration information reported by the TA.

[0203] The configuration information measured by the TA may include: an identifier of the measurement configuration information, a measurement target, and information about the time when the measurement is performed, etc. The configuration information reported by the TA may include: an identifier of the reported configuration information, and information about the time when the report is made, etc. This disclosure does not limit this.

[0204] In the present disclosure, TA measurement configuration information can be used to instruct a terminal device to perform TA measurement to determine the delay from the terminal device to the network device. TA reporting configuration information can be used to instruct a terminal device on how to perform TA reporting. The identifier of the measurement configuration information can be any information that can uniquely identify the measurement configuration, such as the measurement configuration information number. The measurement target can be a measurement signal assigned by the network device to the terminal device. The identifier of the reporting configuration information can be any information that can uniquely identify the reporting configuration, such as the reporting configuration number.

[0205] In the present disclosure, the network device can directly send the TA measurement configuration information or the TA reporting configuration information to the terminal device. Alternatively, when the network device has sent multiple TA measurement configuration information to the terminal device, the network device can send the identification of the measurement configuration information to the terminal device. After receiving the TA measurement configuration information sent by the network device, the terminal device can determine the TA measurement-related configuration according to the identification of the reporting configuration information, and then perform TA measurement according to the measurement configuration. When the network device has sent multiple TA reporting configuration information to the terminal device, the network device can send the identification of the reporting configuration information to the terminal device. The terminal device can determine the reporting-related configuration according to the identification of the reporting configuration information, and then perform TA reporting according to the reported time information.

[0206] Optionally, the network device may configure the fourth indication information in system information, or radio resource control (RRC) signaling, or media access control sublayer information (MAC CE), or physical layer signaling. This disclosure does not impose any restrictions on this.

[0207] Optionally, the terminal device may also determine the configuration information reported by the TA based on preset rules.

[0208] Step 1402: Send location information of the terminal device to the network device, where the location information is determined by the terminal device by measuring signals from multiple satellites.

[0209] Step 1403: When it is determined that the location information meets the preset conditions, the TA reporting is performed in advance.

[0210] In the present disclosure, the specific implementation process of step 1402-step 1403 can be found in the detailed description of any embodiment in the present disclosure, and will not be repeated here.

[0211] It should be noted that the present disclosure does not limit the execution order of step 1402 and step 1401, that is, step 1402 and step 1401 can be executed simultaneously, or step 1402 can be executed first and then step 1401. The present disclosure does not limit this.

[0212] In the present disclosure, upon receiving a fourth indication message sent by the network device indicating TA measurement configuration information and / or TA reporting configuration information, the network device may transmit to the network device the location information of the terminal device determined by measuring signals from multiple satellites. Subsequently, upon determining that the location information meets preset conditions, the network device may perform timing advance TA reporting. Thus, the network device can verify the location information reported by the terminal device based on the reported timing advance TA, thereby avoiding resource scheduling conflicts and ensuring communication reliability.

[0213] See Figure 15 , Figure 15 FIG. 1 is a flow chart of a method for determining location information provided by an embodiment of the present disclosure, and the method is executed by a terminal device. Figure 15 As shown, the method may include but is not limited to the following steps:

[0214] Step 1501: Send location information of a terminal device to a network device, wherein the location information is determined by the terminal device by measuring signals from multiple satellites.

[0215] Step 1502: When it is determined that the location information meets the preset conditions, a timed advance TA reporting is performed.

[0216] Step 1503: Receive fifth indication information sent by the network device, where the fifth indication information is used to instruct the terminal to release the wireless link connection or re-report the location information.

[0217] In the present disclosure, after receiving the TA reported by the terminal device, the network device can determine the credibility of the location information reported by the terminal device based on the TA. If the credibility is less than a preset threshold, the network device can send fifth indication information to the terminal device to instruct the terminal device to release the wireless link connection or re-report the location information. As a result, the terminal device interface re-reports the location information or releases the wireless link connection based on the fifth indication information.

[0218] In the present disclosure, any bit in the sending instruction can be used to identify the fifth indication information. For example, if the fifth indication information is used to instruct the terminal to release the wireless link connection, this bit can be set to 0; if the fifth indication information is used to instruct the terminal to re-report the location information, this bit can be set to 1.

[0219] In the present disclosure, after a terminal device sends location information determined by measuring signals from multiple satellites to a network device, it can perform a timed advance (TA) report if it determines that the location information meets preset conditions. Subsequently, the terminal device can receive fifth indication information from the network device that instructs the terminal to release the radio link connection or re-report the location information. This improves the reliability of the terminal device's location information, avoids resource scheduling conflicts, and ensures communication reliability.

[0220] See Figure 16 , which is a structural diagram of a communication device 1600 provided in an embodiment of the present disclosure.
