Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method and apparatus for determining the effective time of GNSS information of a Global Navigation Satellite System. Background Technology

[0002] In the research of wireless communication technology, satellite communication is considered an important aspect of the future development of wireless communication technology. Satellite communication refers to communication conducted by terrestrial radio communication equipment using satellites as relays. The characteristics of satellite communication are: large communication range; communication can be conducted between any two points within the coverage area of ​​the satellite's emitted radio waves; and it is not easily affected by land-based disasters (high reliability). As a supplement to current terrestrial cellular communication systems, it is foreseeable that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration, truly realizing the Internet of Things.

[0003] In satellite communication scenarios, the long signal transmission distance between the transmitter and receiver leads to significant data transmission delays. For transmissions involving uplink and downlink connections, the terminal needs to maintain uplink synchronization based on Global Navigation Satellite System (GNSS) measurements and other auxiliary information. However, in the 3rd Generation Partnership Project (3GPP) R18 standard, when supporting services with long transmission times, if GNSS information expires, the terminal needs to disconnect from the network and enter an idle state to re-execute the GNSS information measurement process. This method cannot keep the GNSS information active, thus failing to support continuous communication between the terminal and the network, and potentially leading to energy consumption.

[0062] Embodiments of this disclosure are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0063] In satellite communication scenarios, the long signal transmission distance between the transmitter and receiver leads to significant data transmission delays. For transmissions involving uplink and downlink connections, the terminal needs to maintain uplink synchronization based on Global Navigation Satellite System (GNSS) measurements and other auxiliary information. However, in the 3rd Generation Partnership Project (3GPP) R18 standard, when supporting services with long transmission times, if GNSS information expires, the terminal needs to disconnect from the network and enter an idle state to re-execute the GNSS information measurement process. This method cannot keep the GNSS information active, thus failing to support continuous communication between the terminal and the network, and potentially leading to energy consumption.

[0064] To address this, this disclosure proposes a method and apparatus for determining the effective time of GNSS information, which can maintain communication between the terminal and the network side even when GNSS information expires, reduce the frequency of GNSS information measurement performed by the terminal, and reduce the energy consumption of the terminal.

[0065] The following section, with reference to the accompanying drawings, provides a detailed description of the method and apparatus for determining the effective time of GNSS information provided in this application.

[0066] Figure 1 A flowchart illustrating a method for determining the effective time of GNSS information according to an embodiment of this disclosure is shown. Figure 1 As shown, this method should be executed by a terminal and may include the following steps.

[0067] Step 101: Report auxiliary information used to determine the effective time of GNSS information. The auxiliary information includes at least one of the following: the terminal's moving speed, the terminal's moving direction, and the current availability time of GNSS information.

[0068] In this embodiment of the present disclosure, after performing GNSS information measurement, the terminal can determine auxiliary information related to the available GNSS information time after the measurement based on its own circumstances, such as its own moving speed and direction of movement. Furthermore, the terminal can report this auxiliary information to the base station, so that the base station can generate configuration information to extend the current GNSS information availability time based on the auxiliary information.

[0069] Step 102: Receive configuration information sent by the base station. The configuration information is used to determine the effective time for updating the current GNSS information.

[0070] The configuration information may include information related to whether to extend the effective time of the current GNSS information and the duration of the extension. The configuration information is transmitted by the base station through higher-layer signaling or physical-layer signaling, where higher-layer signaling may include system information, Radio Resource Control (RRC) signaling, or Media Access Control (MAC) control elements (CE).

[0071] In specific application scenarios, the terminal can receive the base station's configuration information either before or after the GNSS information expires. For example, in one implementation, the terminal can detect the base station's configuration information within a predefined time range before the GNSS information expires. In another possible implementation, the terminal can receive the configuration information sent by the base station after the GNSS information has expired, without entering an idle state.

[0072] Step 103: Determine the effective time of the current GNSS information.

[0073] In this embodiment of the disclosure, the effective time of the current GNSS information can be determined based on the received configuration information while the terminal maintains a communication connection with the base station (without entering the IDLE state) before or after the current GNSS information becomes invalid. Alternatively, the terminal can enter the IDLE state after the current GNSS information becomes invalid and re-perform GNSS measurements to determine the GNSS information.

[0074] One possible implementation is to extend the effective time of the current GNSS information based on the configuration information received from the base station. In this implementation, the configuration information may carry an indication to extend the effective time of the current GNSS information; correspondingly, upon receiving the configuration information, the effective time of the current GNSS information can be directly extended based on the configuration information. Alternatively, the configuration information may not carry an indication to extend the effective time of the current GNSS information. Upon receiving the configuration information, the terminal does not directly perform the GNSS information effective time extension operation; instead, it needs to receive a first indication information from the base station indicating the extension of the effective time of the current GNSS information, and further respond to the first indication information to extend the effective time of the current GNSS information based on the configuration information.

[0075] As one possible implementation, in response to the absence of a first indication message or in response to the receipt of a second indication message indicating that the effective time should not be extended, the control terminal may further enter an IDLE state after the current GNSS information expires, and simultaneously remeasure the GNSS information. In this implementation, the terminal performs GNSS information measurement within the next GNSS measurement window based on a pre-configured or pre-defined GNSS measurement window configuration. The terminal receives a timing adjustment command sent by the base station, determines the uplink timing based on the new timing adjustment command, and performs uplink data transmission.

[0076] In summary, the method for determining the effective time of GNSS information provided in this disclosure can determine the effective time of GNSS information by extending or re-measuring when GNSS information fails, thereby keeping the GNSS information in an effective state, supporting continuous communication between the terminal and the network side, and reducing the frequency of GNSS information measurement by the terminal, thus reducing the energy consumption of the terminal.

[0077] Figure 2 A flowchart illustrating a method for determining the effective time of GNSS information according to an embodiment of this disclosure is shown. This method is executed by a terminal and is based on... Figure 1 The illustrated embodiment, as Figure 2 As shown, it may include the following steps.

[0078] Step 201: Receive configuration information sent by the base station before the current GNSS information expires. The configuration information includes at least one of the following: the first time length during which the current GNSS information extension takes effect and the extension start time.

[0079] In this embodiment of the disclosure, the terminal can detect the base station's configuration information within a predefined time range before the GNSS information expires. The configuration information is transmitted by the base station via higher-layer signaling or physical-layer signaling. Higher-layer signaling may include system information, Radio Resource Control (RRC) signaling, or Media Access Control (MAC) control elements (CE).

[0080] Step 202: At the expiration time and / or extension start time of the current GNSS information, extend the effective time of the current GNSS information, and the extension length of the effective time is the first time length.

[0081] In one implementation of this disclosure, before the current GNSS information expires, the terminal receives configuration information sent by the base station. After the current GNSS information expires, the terminal can extend the available effective time of the current GNSS information based on the configuration information. During the extended effective time, the terminal does not perform GNSS information measurement operations. Figure 3 As shown, when the terminal determines that the current GNSS information is about to expire, it receives configuration information sent by the base station. The base station's configuration information indicates that the effective time extension length is a first time length, and can also indicate that the extension start time point is A. Therefore, the terminal can further extend the effective time by a length at the current GNSS information expiration time point and / or the extension start time point A. During the extended effective time, the terminal does not perform GNSS information measurement operations.

[0082] In summary, the method for determining the effective time of GNSS information provided in this disclosure can receive configuration information for extending the current GNSS information before the GNSS information expires, and further determine the effective time of the GNSS information based on the extended configuration information, thereby keeping the GNSS information in an effective state, supporting continuous communication between the terminal and the network side, thereby reducing the frequency of the terminal performing GNSS information measurements and reducing the terminal's energy consumption.

[0083] Figure 4 A flowchart illustrating a method for determining the effective time of GNSS information according to an embodiment of this disclosure is shown. This method is executed by a terminal and is based on... Figure 1 The illustrated embodiment, as Figure 4As shown, it may include the following steps.

[0084] Step 301: After the current GNSS information expires, receive configuration information sent by the base station. The configuration information includes at least one of the following: the second time length during which the current GNSS information extension takes effect and the extension start time.

[0085] In this embodiment of the present disclosure, the terminal can receive configuration information from the base station after the GNSS information expires. The configuration information is transmitted by the base station via higher-layer signaling or physical-layer signaling. Higher-layer signaling may include system information, Radio Resource Control (RRC) signaling, or Media Access Control (MAC) control elements (CE).

[0086] Step 302: At the start time of the extension, extend the effective time of the current GNSS information, and the extension length of the effective time is the second time length.

[0087] In one implementation of this disclosure, after the current GNSS information expires, the control does not enter the IDLE state. Upon receiving configuration information from the base station, the available effective time of the current GNSS information is extended at the extension start time indicated by the configuration information. During the extended effective time, the terminal does not perform GNSS information measurement operations. Figure 5 As shown, when the terminal determines that the current GNSS information has expired, it receives configuration information sent by the base station. The base station's configuration information indicates that the extension start time point is B and the effective time extension length is the second time length b. Therefore, the terminal can further extend the effective time by a length of b at the extension start time point B indicated by the configuration information. During the extended effective time, the terminal does not perform GNSS information measurement operations.

[0088] In summary, the method for determining the effective time of GNSS information provided in this disclosure can receive configuration information for extending the current GNSS information after the GNSS information becomes invalid, and further determine the effective time of the GNSS information based on the extended configuration information, thereby keeping the GNSS information in an effective state, supporting continuous communication between the terminal and the network side, thereby reducing the frequency of the terminal performing GNSS information measurements and reducing the terminal's energy consumption.

[0089] Figure 6 This is a flowchart illustrating a method for determining the effective time of GNSS information according to an embodiment of this disclosure. The method is executed by a base station and may include the following steps.

[0090] Step 401: Receive auxiliary information reported by the terminal for determining the effective time of GNSS information. The auxiliary information includes at least one of the terminal's moving speed, the terminal's moving direction, and the current availability time of GNSS information.

[0091] In specific application scenarios, after performing GNSS information measurements, the terminal can determine auxiliary information related to the available GNSS information time after the measurement based on its own circumstances, such as its own movement speed and direction. Furthermore, the terminal can report this auxiliary information to the base station. The base station can then receive this auxiliary information and generate configuration information to extend the current GNSS information validity period based on it.

[0092] Step 402: Send configuration information to the terminal. The configuration information is used to determine the effective time for updating the current GNSS information.

[0093] The configuration information may include information related to whether to extend the effective time of the current GNSS information and the duration of the extension. After generating the configuration information based on the auxiliary information, the base station can send the configuration information to the terminal through higher-layer signaling or physical-layer signaling bearers. The higher-layer signaling may include system information, Radio Resource Control (RRC) signaling, or Media Access Control (MAC) control elements (CE).

[0094] In specific application scenarios, the base station can send configuration information to the terminal before or after the GNSS information expires. For example, in one implementation, the base station can send configuration information to the terminal within a predefined time range before the GNSS information expires. In another possible implementation, the base station can send configuration information to the terminal that has not entered the IDLE state after the GNSS information has expired.

[0095] Accordingly, as one possible implementation, the configuration information sent to the terminal can directly include an indication to extend the current GNSS information validity period, so that the terminal can directly extend the current GNSS information validity period according to the configuration information after receiving it. As another possible implementation, the configuration information sent to the terminal may not include an indication to extend the current GNSS information validity period. After sending the configuration information to the terminal, a first indication information to extend the current GNSS information validity period can be sent to the terminal, so that after receiving the configuration information, the terminal needs to wait for the first indication information sent by the base station, and further respond to the received first indication information to extend the current GNSS information validity period according to the configuration information.

[0096] As one possible implementation, a second indication message can be sent to the terminal, indicating that the effective time should not be extended. This allows the terminal to enter an IDLE state after the current GNSS information expires, and simultaneously remeasure the GNSS information. In this implementation, the terminal performs GNSS information measurement within the next GNSS measurement window based on a pre-configured or pre-defined GNSS measurement window. The terminal receives a timing adjustment command from the base station, determines the uplink timing based on the new timing adjustment command, and performs uplink data transmission.

[0097] In summary, the method for determining the effective time of GNSS information provided in this disclosure can keep the GNSS information active when it fails by sending configuration information for extended GNSS information to the terminal or instructing the terminal to remeasure the effective time of the GNSS information. This supports continuous communication between the terminal and the network side, thereby reducing the frequency of GNSS information measurement by the terminal and reducing the energy consumption of the terminal.

[0098] Figure 7 A flowchart illustrating a method for determining the effective time of GNSS information according to an embodiment of this disclosure is shown. This method is executed by a base station and is based on... Figure 6 The illustrated embodiment, as Figure 7 As shown, it may include the following steps.

[0099] Step 501: Before the current GNSS information expires, send configuration information to the terminal. The configuration information is used by the terminal to extend the effective time of the current GNSS information at the expiration time and / or extension start time. The extension length of the effective time is the first time length.

[0100] In this embodiment of the present disclosure, the terminal can send configuration information to itself within a predefined time range before the GNSS information expires. This allows the terminal to extend the available effective time length of the current GNSS information after it becomes invalid, at the current GNSS information's expiration time and / or extension start time. The extended effective time is a first time length. During the extended effective time, the terminal does not perform GNSS information measurement operations. The specific implementation process can be found in steps 201 to 202 of the embodiment, and will not be repeated here. The configuration information includes at least one of the first effective time length of the extended GNSS information and the extension start time. The configuration information is transmitted by the base station via higher-layer signaling or physical-layer signaling. The higher-layer signaling may include system information, Radio Resource Control (RRC) signaling, or Media Access Control (MAC) control element (CE).

[0101] In summary, the method for determining the effective time of GNSS information provided in this disclosure can send configuration information for extending the current GNSS information to the terminal before the GNSS information expires, so that the terminal can extend the effective time of the GNSS information according to the configuration information, thereby keeping the GNSS information in an effective state, supporting continuous communication between the terminal and the network side, thereby reducing the frequency of the terminal performing GNSS information measurements and reducing the terminal's energy consumption.

[0102] Figure 8 A flowchart illustrating a method for determining the effective time of GNSS information according to an embodiment of this disclosure is shown. This method is executed by a base station and is based on... Figure 6 The illustrated embodiment, as Figure 8 As shown, it may include the following steps.

[0103] Step 601: After the current GNSS information expires, send configuration information to the terminal. The configuration information is used by the terminal to extend the effective time of the current GNSS information at the extension start time point. The extension length of the effective time is the second time length.

[0104] In this embodiment of the present disclosure, the base station can send configuration information to the terminal after the GNSS information expires, so that the terminal extends the available effective time length of the current GNSS information at the extension start time point indicated by the configuration information. The extension length is a second time length. During the extended effective time, the terminal does not perform GNSS information measurement operations. The specific implementation process can be found in steps 301 to 302 of the embodiment, and will not be repeated here. The second configuration information includes at least one of the second effective time length of the current GNSS information extension and the extension start time point. The configuration information is sent by the base station through higher-layer signaling or physical-layer signaling. The higher-layer signaling may include system information, Radio Resource Control (RRC) signaling, or Media Access Control (MAC) control element (CE).

[0105] In summary, the method for determining the effective time of GNSS information provided in this disclosure can send configuration information for extending the current GNSS information to the terminal after the GNSS information becomes invalid, so that the terminal can extend the effective time of the GNSS information according to the configuration information, thereby keeping the GNSS information in an effective state, supporting continuous communication between the terminal and the network side, thereby reducing the frequency of the terminal performing GNSS information measurements and reducing the terminal's energy consumption.

[0106] Figure 9 This is a timing diagram of a method for determining the effective time of GNSS information according to an embodiment of this disclosure. The method is applied to a communication system for determining the effective time of GNSS information. The system includes: a terminal and a base station. The terminal reports auxiliary information for determining the effective time of GNSS information. The auxiliary information includes at least one of the terminal's moving speed, the terminal's moving direction, and the current availability time of the GNSS information. The base station determines configuration information based on the auxiliary information regarding the effective time of the GNSS information. The configuration information is used to extend the effective time of the current GNSS information. The base station sends the configuration information to the terminal. The terminal determines the effective time of the current GNSS information.

[0107] See Figure 9 The method includes the following steps.

[0108] Step 701: The terminal reports auxiliary information used to determine the effective time of GNSS information.

[0109] The auxiliary information includes at least one of the following: the terminal's moving speed, the terminal's moving direction, and the availability time of the current GNSS information.

[0110] In this embodiment of the present disclosure, after performing GNSS information measurement, the terminal can determine auxiliary information related to the available GNSS information time after the measurement based on its own circumstances, such as its own moving speed and direction of movement. Furthermore, the terminal can report this auxiliary information to the base station, so that the base station can generate configuration information to extend the current GNSS information availability time based on the auxiliary information.

[0111] Step 702: The base station determines the configuration information based on the auxiliary information of the GNSS information effective time. The configuration information is used to determine the effective time for updating the current GNSS information.

[0112] The configuration information may include information related to whether to extend the current GNSS information and the duration of the extension.

[0113] Step 703: The base station sends configuration information to the terminal.

[0114] In the embodiments of this disclosure, after generating configuration information based on auxiliary information, the base station can send the configuration information to the terminal through higher-layer signaling or physical-layer signaling bearers. The higher-layer signaling may include system information, Radio Resource Control (RRC) signaling, or Media Access Control (MAC) control element (CE).

[0115] In one possible implementation, the configuration information may include at least one of the first duration of the current GNSS information extension being effective and the extension start time point; in another possible implementation, the configuration information may include at least one of the second duration of the current GNSS information extension being effective and the extension start time point.

[0116] Step 704: The terminal determines the effective time of the current GNSS information.

[0117] As one possible implementation, before the current GNSS information expires, the terminal can receive configuration information sent by the base station. After the current GNSS information expires, at the expiration time and / or the start time of the extension, the available valid time length of the current GNSS information can be extended, where the extended length is a first time length. During the extended effective time, the terminal does not perform GNSS information measurement operations.

[0118] As one possible implementation, after the current GNSS information expires, the terminal can receive second configuration information sent by the base station. At the extension start time indicated by the second configuration information, the available effective time length of the current GNSS information can be extended by the second time length. During the extended effective time, the terminal does not perform GNSS information measurement operations.

[0119] As one possible implementation, after the current GNSS information expires, the control terminal enters the IDLE state and simultaneously remeasures and determines the GNSS information.

[0120] By applying the method for determining the effective time of GNSS information provided in this embodiment, the effective time of GNSS information can be determined by extension or remeasurement when GNSS information fails.
