[0042] In order to better understand the method for determining the GNSS measurement capability disclosed in the embodiments of the present application, the communication system to which the embodiments of the present application are applicable will be described first.

[0043] Please refer to Figure 1 , Figure 1 The architecture of a communication system provided by the embodiments of the present application is shown in the figure. The communication system can include, but is not limited to, one network device and one terminal device, Figure 1 The number and form of devices shown in the figure are only for example and do not constitute a limitation on the embodiments of the present application.

[0044] It should be noted that the technical solutions of the embodiments of the present application can be applied to various communication systems. For example: Long Term Evolution (LTE) system, fifth generation mobile communication system, 5G new air interface system, or other future new mobile communication systems, etc.

[0045] The network device 101 in the embodiments of the present application is an entity for transmitting or receiving signals on the network side. For example, the network device 11 can be an evolved node B (eNB), a transmission reception point (TRP), a next generation node B (gNB) in the NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (Wi-Fi) system, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0047] In the present disclosure, the terminal device 12 can be used to implement Figures 2 to 4 The network device 11 can be used to implement the method shown in any embodiment as Figures 5 to 7 The method shown in any embodiment.

[0048] With the continuous development of wireless communication technology, satellite communication is considered an important aspect of the development of future wireless communication technology. In the scenario of satellite communication, due to the long signal transmission distance between the sending end and the receiving end, there is a large time delay in data transmission. For transmission with uplink and downlink relationship, the current standardization discussion determines to introduce a parameter of offset Koffset to compensate for the transmission delay.

[0049] The terminal device can compensate for the transmission delay through ephemeris information and related information of common timing advance (common TA). The ephemeris information and common TA information are notified to the terminal device through system information.

[0050] In a satellite communication scenario, a terminal device needs to obtain its own position information to facilitate compensation for uplink synchronization. When transmitting a service with a long transmission time, if global navigation satellite system (GNSS) information is outdated, the terminal device needs to reacquire GNSS information.

[0051] For some terminal devices (such as Internet of Things (IoT) terminal devices), a wireless cellular network (cellular) module and a GNSS module can not be supported to work simultaneously. In the related art, only wireless cellular network and GNSS measurement sporadic transmission is supported. When the terminal device acquires GNSS information, it enters an idle state (id), which increases the transmission delay and increases the power consumption of the terminal device. For different terminal devices, there can be different GNSS measurement capabilities, and the network device can perform appropriate operations according to the GNSS measurement capability of the terminal device. Therefore, in the present disclosure, a global navigation satellite system (GNSS) measurement capability determination method is proposed, in which the terminal device reports its GNSS measurement capability to the network device, so that the network device can accurately determine the GNSS measurement capability of the terminal device in a timely manner, and then perform appropriate operations to avoid the consumption of the power of the terminal device.

[0052] It can be understood that the communication system described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of system architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0053] The global navigation satellite system (GNSS) measurement capability determination method and device provided by the present application will be described in detail below in combination with the accompanying drawings.

[0054] Please refer to Figure 2 , Figure 2 is a flowchart of a global navigation satellite system (GNSS) measurement capability determination method provided by the embodiments of the present application. It should be noted that the global navigation satellite system (GNSS) measurement capability determination method of the embodiments of the present application is executed by a terminal device. The method can be executed independently, or can be executed together with any other embodiment of the present application. As Figure 2 indicated, the method can include the following steps:

[0055] In step 201, the terminal device sends the GNSS measurement capability of the terminal device to the network device, the GNSS measurement capability comprising at least one of the following: whether the terminal device supports simultaneous operation of the wireless cellular network system and GNSS measurement, and a length of time required for obtaining a GNSS measurement result.

[0056] In the present disclosure, the length of time required for obtaining a GNSS measurement result refers to the length of time required for the terminal to obtain a GNSS measurement result. When the terminal is measuring GNSS, the wireless cellular of the terminal can be in a connected or unconnected state.

[0057] In some embodiments, the terminal device supports simultaneous operation of the wireless cellular network system and GNSS measurement. That is, the terminal device can maintain a wireless communication connection with the network device while performing GNSS positioning measurement, or further, the terminal device can maintain data interaction with the network device while performing GNSS positioning measurement without entering an IDLE state.

[0058] In some embodiments, the terminal device does not support simultaneous operation of the wireless cellular network system and GNSS measurement. That is, the terminal device cannot maintain wireless communication interaction with the network device while performing positioning measurement and needs to enter an IDLE state.

[0059] In some embodiments, the terminal device supports simultaneous operation of the wireless cellular network system and GNSS measurement, but the length of time required for obtaining a GNSS measurement result can be different from that of other terminal devices. Therefore, the terminal device can further send the length of time required for obtaining a GNSS measurement result to the network device. Subsequently, the network device can perform appropriate operations, such as selecting a timing for sending a control instruction to the terminal device, according to the length of time required for obtaining a GNSS measurement result.

[0060] In some embodiments, the terminal device does not support simultaneous operation of the wireless cellular network system and GNSS measurement, and the length of time required for obtaining a GNSS measurement result can be different from that of other terminal devices. Therefore, the terminal device can further send the length of time required for obtaining a GNSS measurement result to the network device. Subsequently, the network device can perform appropriate operations, such as selecting a timing for sending a control instruction to the terminal device, according to the length of time required for obtaining a GNSS measurement result.

[0061] Optionally, the terminal device can indicate its GNSS measurement capability to the network device in a displayed manner, or can indicate its GNSS measurement capability to the network device in an implicit manner.

[0062] Optionally, the terminal device can send first indication information to the network device to indicate its GNSS measurement capability. The first indication information includes an information field indicating the GNSS measurement capability of the terminal device. For example, if the value of the information field is "0", it indicates that the terminal device does not support simultaneous operation of the wireless cellular network system and GNSS measurement; if the value of the information field is "1", it indicates that the terminal device supports simultaneous operation of the wireless cellular network system and GNSS measurement.

[0063] Further, if the time length required by different terminal devices to obtain GNSS measurement results can be different, for example, the time length required by some terminal devices to obtain GNSS measurement results is t1, and the time length required by some terminal devices to obtain GNSS measurement results is t2. The information field of the first indication information can use two bits to indicate the GNSS measurement capability of the terminal device.

[0064] For example, if the value of the information field is "00", it indicates that the terminal device does not support simultaneous operation of the wireless cellular network system and GNSS measurement. If the value of the information field is "01", it indicates that the terminal device supports simultaneous operation of the wireless cellular network system and GNSS measurement, but only supports maintaining the connection of the wireless cellular network when performing GNSS measurement, that is, the terminal device does not expect to receive control instructions sent by the network device at this time. If the value of the information field is "10", it indicates that the terminal device supports simultaneous operation of the wireless cellular network system and GNSS measurement, and the GNSS measurement capability of the terminal device is specifically the first type of capability. If the value of the information field is "11", it indicates that the terminal device supports simultaneous operation of the wireless cellular network system and GNSS measurement, and the GNSS measurement capability of the terminal device is specifically the second type of capability. In some possible implementation forms, different types of GNSS measurement capability not only include different time lengths required by the terminal device to obtain GNSS measurement results, but also can include different valid time lengths of the GNSS measurement results, which are not limited in the present disclosure.

[0065] Optionally, the terminal device can also implicitly send its GNSS measurement capability to the network device by reporting its GNSS measurement assistance information.

[0066] The GNSS measurement assistance information can include at least one of the following: the time length required to obtain the GNSS measurement result, and the valid time length of the GNSS measurement result.

[0067] The terminal device can implicitly indicate to the network device whether it supports simultaneous operation of the wireless cellular network system and GNSS measurement by setting any one of the GNSS measurement assistance information to a specified value.

[0068] For example, the terminal device can set the length of time required to obtain GNSS measurement results to a specified value, such as infinite, to indicate to the network device that the terminal device does not support simultaneous operation of the wireless cellular network system and GNSS measurement.

[0069] In some possible implementation forms, if the terminal device does not support simultaneous operation of the wireless cellular network system and GNSS measurement, the terminal device does not expect to receive an instruction to perform GNSS measurement sent by the network device when in the connected state, so that the terminal device stops monitoring the instruction sent by the network device to trigger GNSS measurement when in the connected state. In addition, in the case that GNSS information expires (for example, when a GNSS validity timer expires), the terminal device enters the IDLE state and performs GNSS measurement.

[0070] In some possible implementation forms, if the terminal device supports simultaneous operation of the wireless cellular network system and GNSS measurement, the terminal device can perform GNSS measurement in the connected state based on triggering or configuration.

[0071] That is, the terminal device can perform GNSS measurement in the connected state based on triggering by the network device, perform GNSS measurement periodically based on a configured GNSS measurement period, or perform GNSS measurement based on a configured GNSS measurement window. The present disclosure does not limit this.

[0072] In summary, the terminal device directly sends the GNSS measurement capability of whether it supports simultaneous operation of the wireless cellular network system and GNSS measurement, or the length of time required to obtain GNSS measurement results, and the like, to the network device. This enables the network device to timely and effectively perform appropriate operations according to the GNSS measurement capability of the terminal device, so as to ensure that the terminal device can timely obtain its own position information, effectively reduce transmission delay, save power consumption of the terminal device, and at the same time, obtain more accurate uplink synchronization compensation information and avoid interference between uplink transmissions of different terminal devices.

[0073] Please refer to Figure 3 , Figure 3 is a flowchart of a method for determining GNSS measurement capability provided by an embodiment of the present application. It should be noted that the method for determining GNSS measurement capability provided by an embodiment of the present application is executed by a terminal device. The method can be executed independently, or can be executed in combination with any other embodiment of the present application. As shown in Figure 3 , the method can include the following steps:

[0074] Step 301, sending a GNSS measurement capability of the terminal device to the network device in an initial access stage.

[0075] The GNSS measurement capability comprises at least one of the following: whether the terminal device supports simultaneous operation of a wireless cellular network system and GNSS measurement, and a length of time required to obtain a GNSS measurement result.

[0076] In the present disclosure, the length of time required to obtain a GNSS measurement result refers to a length of time required by the terminal device to obtain a GNSS measurement result. When the terminal device measures GNSS, the wireless cellular network of the terminal device can be in a connected state or an unconnected state.

[0077] That is, the terminal device can send its GNSS measurement capability to the network device when initially accessing the wireless cellular network system, so that the network device performs appropriate operations according to the GNSS measurement capability.

[0078] In some possible implementation forms, the terminal device can send a preamble sequence corresponding to the GNSS measurement capability to the network device in the initial access stage.

[0079] Optionally, the terminal device can determine a mapping relationship between the GNSS measurement capability and the preamble sequence according to a protocol agreement, and then select a preamble sequence corresponding to the GNSS measurement capability of the terminal device and send the preamble sequence to the network device in the initial access stage.

[0080] Optionally, the terminal device can also determine the mapping relationship between the GNSS measurement capability and the preamble sequence according to first information sent by the network device, and then select a preamble sequence corresponding to the GNSS measurement capability of the terminal device and send the preamble sequence to the network device in the initial access stage. The first information can be system information or any other information, which is not limited in the present disclosure.

[0081] In some possible implementation forms, the terminal device can also send a preamble sequence to the network device using a resource position corresponding to the GNSS measurement capability in the initial access stage.

[0082] That is, different preamble sequence sending resource positions correspond to different GNSS measurement capabilities. Therefore, the terminal device can select a resource position corresponding to the GNSS measurement capability of the terminal device to send a preamble sequence in the initial access stage, and then the network device can determine the GNSS measurement capability of the terminal device according to a resource position of a received preamble sequence.

[0083] Optionally, the terminal device can determine the mapping relationship between the GNSS measurement capability and the resource location according to a protocol agreement. Then in the initial access stage, the terminal device selects the resource location corresponding to its own GNSS measurement capability, and sends the preamble sequence to the network device.

[0084] Optionally, the terminal device can also determine the mapping relationship between the GNSS measurement capability and the resource location according to the second information sent by the network device. Then in the initial access stage, the terminal device selects the resource location corresponding to its own GNSS measurement capability, and sends the preamble sequence to the network device. The second information can be system information or any other information, which is not limited in the disclosure.

[0085] In some possible implementation forms, the terminal device can also send the GNSS measurement capability to the network device through a third access message.

[0086] Optionally, the terminal device can carry first indication information for indicating the GNSS measurement capability in the third access message; or the terminal device can also carry GNSS measurement assistance information in the third access message to implicitly indicate its GNSS measurement capability.

[0087] The specific implementation forms of the first indication information and the GNSS measurement assistance information can refer to the detailed description of any embodiment of the disclosure, which will not be described here.

[0088] In some possible implementation forms, if the terminal device does not support the wireless cellular network system and the GNSS measurement to work simultaneously, the terminal device does not expect to receive the instruction for performing the GNSS measurement sent by the network device when in the connected state, so that the terminal device stops listening to the instruction for triggering the GNSS measurement sent by the network device when in the connected state. And in the case that the GNSS information is expired (for example, when the validity timer (validity timer) is timed out, the terminal device enters the IDLE state and performs the GNSS measurement.

[0089] In some possible implementation forms, if the terminal device supports the wireless cellular network system and the GNSS measurement to work simultaneously, the terminal device can perform the GNSS measurement in the connected state based on the trigger or the configuration.

[0090] That is, the terminal device can perform the GNSS measurement in the connected state based on the trigger of the network device, or perform the GNSS measurement periodically based on the configured GNSS measurement period, or perform the GNSS measurement based on the configured GNSS measurement window, which is not limited in the disclosure.

[0091] In summary, the terminal device sends its GNSS measurement capabilities to the network device during the initial access phase. This enables the network device to perform appropriate operations promptly and effectively based on the terminal device's GNSS measurement capabilities, ensuring that the terminal device can obtain its own location information in a timely manner, effectively reducing transmission latency, saving power consumption, and obtaining more accurate uplink synchronization compensation information, thus avoiding interference in uplink transmission between different terminal devices.

[0092] Please see Figure 4 , Figure 4 This is a flowchart illustrating a method for determining the GNSS measurement capability of a Global Navigation Satellite System (GNSS) according to an embodiment of this application. It should be noted that the method for determining the GNSS measurement capability of a GNSS system according to this embodiment is executed by a terminal device. This method can be executed independently or in conjunction with any other embodiment of this application. Figure 4 As shown, the method may include the following steps:

[0093] Step 401: After entering the connected state, send the GNSS measurement capability of the terminal device to the network device.

[0094] Among them, GNSS measurement capabilities include at least one of the following: whether the terminal equipment supports simultaneous operation of wireless cellular network system and GNSS measurement, and the time required to obtain GNSS measurement results.

[0095] In this disclosure, "the time required to obtain GNSS measurement results" refers to the time required for the terminal device to obtain GNSS measurement results. When the terminal is measuring GNSS, its wireless cellular network may be connected or disconnected.

[0096] In some possible implementations, the terminal device can send a first indication message to the network device after entering the connected state to explicitly indicate its GNSS measurement capabilities.

[0097] The implementation of the first instruction information can be described in detail with reference to any embodiment of this disclosure, and will not be repeated here.

[0098] In some possible implementations, the terminal device may also send GNSS measurement assistance information to the network device after entering the connected state to implicitly indicate its GNSS measurement capabilities. The specific method by which the terminal device indicates its GNSS measurement capabilities through GNSS measurement assistance information can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0099] In some possible implementations, the terminal device can send GNSS measurement capabilities to the network device based on the GNSS measurement cycle.

[0100] That is, the terminal device can report its GNSS measurement capability to the network device once before each GNSS measurement window arrives or after each GNSS measurement is completed. It should be noted that the GNSS measurement capability of the terminal device can be fixed or can also be variable, which is not limited in the disclosure.

[0101] Optionally, the terminal device can also send the GNSS measurement capability to the network device based on the triggering instruction of the network device.

[0102] That is, after entering the connected state, the terminal device can send its GNSS measurement capability to the network device after receiving the triggering instruction of the network device.

[0103] In some possible implementation forms, if the terminal device does not support the wireless cellular network system and the GNSS measurement to work simultaneously, the terminal device is not expected to receive the instruction for performing the GNSS measurement sent by the network device when in the connected state, so that the terminal device stops listening to the instruction for triggering the GNSS measurement sent by the network device when in the connected state. And in the case that the GNSS information is expired (for example, when the validity timer (validity timer) is timed out, the terminal device enters the IDLE state and performs the GNSS measurement.

[0104] In some possible implementation forms, if the terminal device supports the wireless cellular network system and the GNSS measurement to work simultaneously, the terminal device can perform the GNSS measurement in the connected state based on triggering or configuration.

[0105] That is, the terminal device can perform the GNSS measurement in the connected state based on the triggering of the network device, or perform the GNSS measurement periodically based on the configured GNSS measurement period, or perform the GNSS measurement based on the configured GNSS measurement window. The disclosure does not limit this.

[0106] In summary, the terminal device sends its GNSS measurement capability to the network device when in the connected state. Therefore, the network device can timely and effectively perform appropriate operations according to the GNSS measurement capability of the terminal device, so as to ensure that the terminal device can obtain its own position information in time, effectively reduce the transmission delay, save the power consumption of the terminal device, and at the same time, obtain more accurate uplink synchronization compensation information and avoid the interference of uplink transmission between different terminal devices.

[0107] See Figure 5 , Figure 5is a flowchart of a method for determining GNSS measurement capability provided by an embodiment of the present application. It should be noted that the method for determining GNSS measurement capability provided by an embodiment of the present application is executed by a network device. The method can be executed independently, or in combination with any other embodiment of the present application. As shown in the method can include the following steps: Figure 5

[0108] Step 501: receiving GNSS measurement capability sent by a terminal device, the GNSS measurement capability including at least one of the following: whether the terminal device supports simultaneous operation of a wireless cellular network system and GNSS measurement, and a length of time required to obtain GNSS measurement results.

[0109] In the present disclosure, the length of time required to obtain GNSS measurement results refers to the length of time required by a terminal device to obtain GNSS measurement results. When the terminal is measuring GNSS, the wireless cellular of the terminal can be in a connected or unconnected state.

[0110] In some embodiments, the terminal device supports simultaneous operation of a wireless cellular network system and GNSS measurement. That is, the terminal device can maintain a wireless communication connection with the network device while performing GNSS positioning measurement, or further, the terminal device can maintain data interaction with the network device while performing GNSS positioning measurement without entering an IDLE state.

[0111] In some embodiments, the terminal device does not support simultaneous operation of a wireless cellular network system and GNSS measurement. That is, the terminal device cannot maintain wireless communication interaction with the network device while performing positioning measurement, and needs to enter an IDLE state.

[0112] In some embodiments, the length of time required by each terminal device that supports simultaneous operation of a wireless cellular network system and GNSS measurement to obtain GNSS measurement results can be different, and therefore the network device can also receive the length of time required by the terminal device to obtain GNSS measurement results sent by the terminal device. Subsequently, the network device can perform appropriate operations, such as selecting a timing for sending a control instruction to the terminal device, according to the length of time required by the terminal device to obtain GNSS measurement results.

[0113] In some embodiments, the length of time required by each terminal device that does not support simultaneous operation of a wireless cellular network system and GNSS measurement to obtain GNSS measurement results can be different, and therefore the network device can also receive the length of time required by the terminal device to obtain GNSS measurement results sent by the terminal device. Subsequently, the network device can perform appropriate operations, such as selecting a timing for sending a control instruction to the terminal device, according to the length of time required by the terminal device to obtain GNSS measurement results.​

[0114] Optionally, the GNSS measurement capability sent by the terminal device and received by the network device can be indicated by the terminal device in a displayed manner or in an implicit manner.

[0115] Optionally, the network device can receive first indication information sent by the terminal device, the first indication information being used to indicate the GNSS measurement capability of the terminal device. The first indication information includes an information field used to indicate the GNSS measurement capability of the terminal device. For example, if the value of the information field is "0", it indicates that the terminal device does not support simultaneous operation of the wireless cellular network system and the GNSS measurement; if the value of the information field is "1", it indicates that the terminal device supports simultaneous operation of the wireless cellular network system and the GNSS measurement.

[0116] Further, if the lengths of time required by different terminal devices to obtain GNSS measurement results can be different, for example, the length of time required by some terminal devices to obtain GNSS measurement results is t1, and the length of time required by some terminal devices to obtain GNSS measurement results is t2. The information field of the first indication information can use two bits to indicate the GNSS measurement capability of the terminal device.

[0117] For example, if the value of the information field is "00", it indicates that the terminal device does not support simultaneous operation of the wireless cellular network system and the GNSS measurement. If the value of the information field is "01", it indicates that the terminal device supports simultaneous operation of the wireless cellular network system and the GNSS measurement, but only supports maintaining the connection of the wireless cellular network when performing the GNSS measurement, that is, the terminal device does not expect to receive the control instruction sent by the network device at this time. If the value of the information field is "10", it indicates that the terminal device supports simultaneous operation of the wireless cellular network system and the GNSS measurement, and the GNSS measurement capability of the terminal device is specifically the first type of capability. If the value of the information field is "11", it indicates that the terminal device supports simultaneous operation of the wireless cellular network system and the GNSS measurement, and the GNSS measurement capability of the terminal device is specifically the second type of capability.

[0118] In some possible implementation forms, the different types of GNSS measurement capabilities not only include different lengths of time required by the terminal device to obtain GNSS measurement results, but also include different valid durations of the GNSS measurement results obtained by the terminal device, which is not limited in the present disclosure.

[0119] Optionally, the network device can also receive the GNSS measurement assistance information of the terminal device sent by the terminal device, the GNSS measurement assistance information being used to indicate the GNSS measurement capability of the terminal device.

[0120] The GNSS measurement assistance information can include at least one of: a length of time required to obtain a GNSS measurement result, a valid duration of the GNSS measurement result.

[0121] After receiving the GNSS measurement assistance information sent by the terminal device, the network device can determine the GNSS measurement capability of the terminal device according to the value of the GNSS measurement assistance information. For example, if the length of time required to obtain a GNSS measurement result in the GNSS measurement assistance information of the terminal device is a specified value, it is determined that the terminal device does not support simultaneous operation of the cellular network system and GNSS measurement.

[0122] For example, when the terminal device does not support simultaneous operation of the wireless cellular network system and GNSS measurement, the terminal device can set the length of time required to obtain a GNSS measurement result to a specified value, such as infinity (infinite). Thus, after receiving the length of time required to obtain a GNSS measurement result sent by the terminal device, if the length value is infinite, the network device can determine that the terminal device does not support simultaneous operation of the wireless cellular network system and GNSS measurement.

[0123] In some possible implementation forms, if the terminal device does not support simultaneous operation of the wireless cellular network system and GNSS measurement, the terminal device does not expect to receive an instruction for performing GNSS measurement sent by the network device when the terminal device is in a connected state. Thus, the network device can stop sending an instruction for triggering the terminal device to perform GNSS measurement to the terminal device when the terminal device is in the connected state.

[0124] In some possible implementation forms, if the terminal device supports simultaneous operation of the wireless cellular network system and GNSS measurement, the network device can send a triggering instruction to the terminal device to trigger the terminal device to perform GNSS measurement in the connected state when the terminal device is in the connected state.

[0125] In summary, the network device receives the GNSS measurement capability of the terminal device, such as whether the terminal device supports simultaneous operation of the wireless cellular network system and GNSS measurement, or the length of time required to obtain a GNSS measurement result. Thus, the network device can perform appropriate operations in a timely and effective manner according to the GNSS measurement capability of the terminal device, so that the terminal device can obtain its own position information in a timely manner, effectively reduce the transmission delay, save the power consumption of the terminal device, obtain more accurate uplink synchronization compensation information, and avoid interference between uplink transmissions of different terminal devices.

[0126] See Figure 6 , Figure 6is a flowchart of a method for determining GNSS measurement capability provided by an embodiment of the present application. It should be noted that the method for determining GNSS measurement capability provided by an embodiment of the present application is executed by a network device. The method can be executed independently, or can be executed in combination with any other embodiment of the present application. As shown in FIG. 6, the method can include the following steps: Figure 6

[0127] Step 601: receiving GNSS measurement capability of a terminal device sent by the terminal device in an initial access stage.

[0128] The GNSS measurement capability includes at least one of the following: whether the terminal device supports simultaneous operation of a wireless cellular network system and GNSS measurement, and a length of time required to obtain a GNSS measurement result.

[0129] In the present disclosure, the length of time required to obtain a GNSS measurement result refers to the length of time required by a terminal device to obtain a GNSS measurement result. When the terminal measures GNSS, the wireless cellular network of the terminal can be in a connected or unconnected state.

[0130] That is, the terminal device can send its GNSS measurement capability to the network device when it accesses the wireless cellular network system for the first time, so that the network device performs appropriate operations according to the GNSS measurement capability of the terminal device.

[0131] In some possible implementation forms, the network device can determine the GNSS measurement capability of the terminal device according to a preamble sequence sent by the terminal device in the initial access stage.

[0132] Optionally, the network device and the terminal device can determine a mapping relationship between the GNSS measurement capability and the preamble sequence according to a protocol agreement. Then, the terminal device can select a preamble sequence corresponding to its own GNSS measurement capability and send the preamble sequence to the network device in the initial access stage. Thus, the network device can determine the GNSS measurement capability of the terminal device according to the received preamble sequence.

[0133] Optionally, the network device can also send first information to the terminal device to indicate the mapping relationship between different GNSS measurement capabilities and preamble sequences. Then, the terminal device can select a preamble sequence corresponding to its own GNSS measurement capability and send the preamble sequence to the network device in the initial access stage. The first information can be system information or any other information, which is not limited in the present disclosure.

[0134] ​In some possible implementation forms, the network device can further determine the GNSS measurement capability of the terminal device according to a resource position at which the terminal device transmits a preamble sequence in the initial access stage.

[0135] That is, different preamble sequence transmission resource positions correspond to different GNSS measurement capabilities. Thus, the terminal device can select a resource position corresponding to its GNSS measurement capability to transmit a preamble sequence in the initial access stage, and then the network device can determine the GNSS measurement capability of the terminal device according to the resource position at which the preamble sequence is received.

[0136] Optionally, the network device and the terminal device can determine the mapping relationship between the GNSS measurement capability and the resource position according to a protocol. Then, in the initial access stage, the terminal device selects a resource position corresponding to its own GNSS measurement capability to transmit a preamble sequence to the network device.

[0137] Optionally, the network device can further send second information to the terminal device to indicate the mapping relationship between the GNSS measurement capability and the resource position. Then, in the initial access stage, the terminal device selects a resource position corresponding to its own GNSS measurement capability to transmit a preamble sequence to the network device. The second information can be system information or any other information, which is not limited in the present disclosure.

[0138] In some possible implementation forms, the network device can further determine the GNSS measurement capability of the terminal device according to information carried in a third access message transmitted by the terminal device in the initial access stage.

[0139] Optionally, the third access message received by the network device can carry first indication information for indicating the GNSS measurement capability, or can carry GNSS measurement assistance information, so that the network device can analyze the third access message to determine the GNSS measurement capability of the terminal device.

[0140] The specific implementation forms of the first indication information and the GNSS measurement assistance information can refer to the detailed description of any embodiment of the present disclosure, which will not be described here again.

[0141] In some possible implementation forms, if the terminal device does not support simultaneous operation of the wireless cellular network system and the GNSS measurement, the terminal device does not expect to receive an instruction for performing GNSS measurement sent by the network device when the terminal device is in a connected state, so that the network device can stop sending an instruction for triggering the terminal device to perform GNSS measurement when the terminal device is in the connected state.

[0142] In some possible implementation forms, if the terminal device supports simultaneous operation of the wireless cellular network system and the GNSS measurement, the network device can send a trigger instruction to the terminal device to trigger the terminal device to perform the GNSS measurement in the connected state.

[0143] In summary, the network device receives the GNSS measurement capability of the terminal device in the initial access stage. Therefore, the network device can perform appropriate operations in a timely and effective manner according to the GNSS measurement capability of the terminal device, so as to ensure that the terminal device can obtain its own position information in a timely manner, effectively reduce the transmission delay, save the power consumption of the terminal device, and at the same time, obtain more accurate uplink synchronization compensation information, and avoid interference between uplink transmissions of different terminal devices.

[0144] Please refer to Figure 7 , Figure 7 is a flowchart of a method for determining a global navigation satellite system (GNSS) measurement capability provided by an embodiment of the present application. It should be noted that the method for determining the GNSS measurement capability of the present embodiment is performed by a network device. The method can be independently executed, or can be executed in combination with any other embodiment of the present application. As shown in Figure 7 , the method can include the following steps:

[0145] Step 701, receiving the GNSS measurement capability of the terminal device sent by the terminal device after entering the connected state.

[0146] The GNSS measurement capability includes at least one of the following: whether the terminal device supports simultaneous operation of the wireless cellular network system and the GNSS measurement, and the length of time required to obtain the GNSS measurement result.

[0147] In the present disclosure, the length of time required to obtain the GNSS measurement result refers to the length of time required by the terminal device to obtain the GNSS measurement result. When the terminal measures the GNSS, the wireless cellular of the terminal can be in a connected or unconnected state.

[0148] In some possible implementation forms, the network device can receive first indication information that can be sent by the terminal device after entering the connected state, and then the network device can determine the GNSS measurement capability of the terminal device according to the value of the specified information field in the first indication information.

[0149] The implementation form of the first indication information can refer to the detailed description of any embodiment of the present disclosure, which will not be repeated here.

[0150] In some possible implementation forms, the network device can further receive GNSS measurement assistance information sent by the terminal device after the terminal device enters the connected state. Then, the network device can determine the GNSS measurement capability of the terminal device according to an indication of the GNSS measurement assistance information. The specific manner in which the GNSS measurement assistance information indicates the GNSS measurement capability of the terminal device can refer to the detailed description of any embodiment of the present disclosure, which will not be described here again.

[0151] In some possible implementation forms, the GNSS measurement capability of the terminal device received by the network device can be the GNSS measurement capability of the terminal device sent to the network device based on a GNSS measurement period of the terminal device.

[0152] That is, the terminal device can report its GNSS measurement capability to the network device once before each GNSS measurement window or after each GNSS measurement. It should be noted that the GNSS measurement capability of the terminal device can be fixed or variable, which is not limited in the present disclosure.

[0153] Optionally, the GNSS measurement capability of the terminal device received by the network device can also be the GNSS measurement capability of the terminal device sent to the network device based on a trigger instruction of the network device.

[0154] That is, the network device can send a trigger instruction to the terminal device to trigger the terminal device to send its GNSS measurement capability to the network device after determining that the terminal device enters the connected state.

[0155] In some possible implementation forms, if the terminal device does not support simultaneous operation of the wireless cellular network system and the GNSS measurement, the terminal device is not expected to receive an instruction for performing GNSS measurement sent by the network device when the terminal device is in the connected state, so that the network device can stop sending the trigger instruction for performing GNSS measurement to the terminal device when the terminal device is in the connected state.

[0156] In some possible implementation forms, if the terminal device supports simultaneous operation of the wireless cellular network system and the GNSS measurement, the network device can send a trigger instruction to the terminal device to trigger the terminal device to perform GNSS measurement in the connected state.

[0157] In summary, the network device can receive the GNSS measurement capability of the terminal device sent by the terminal device in the connected state. Therefore, the network device can timely and effectively perform appropriate operations according to the GNSS measurement capability of the terminal device, so as to ensure that the terminal device can timely acquire its own position information, effectively reduce the transmission delay, save the power consumption of the terminal device, and at the same time, more accurate uplink synchronization compensation information can be acquired, and the interference between different terminal devices in uplink transmission can be avoided.
