When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this application as detailed in the appended claims.

[0053] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application.

[0054] It should be understood that although the terms first, second, third, etc., may be used to describe various information in the embodiments of this application, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the words "if" and "suppose" as used herein can be interpreted as "when," "when," or "in response to a determination."

[0055] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0056] To better understand the method for obtaining the effective time disclosed in the embodiments of this application, the communication system to which the embodiments of this application are applicable is described below.

[0057] Please see Figure 1a , Figure 1a This application provides a schematic diagram of the architecture of a communication system. The communication system may include, but is not limited to, a first network device, a second network device, and a terminal device. Figure 1a The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this application. In actual applications, it may include two or more network devices and two or more terminal devices. Figure 1a The communication system shown is exemplified by a network device 101 and a terminal device 102.

[0058] It should be noted that the technical solutions of this application embodiment can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, fifth-generation mobile communication systems, 5G New Radio systems, or other future new mobile communication systems.

[0059] The network device 101 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a Transmission Reception 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. This application does not limit the specific technology or device form used in the network device. The network device provided in this embodiment can be composed of a Central Unit (CU) and a Distributed Unit (DU). The CU can also be called a Control Unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining partial or complete protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0060] In this embodiment, the terminal device 102 is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. Terminal devices can be vehicles with communication capabilities, smart cars, mobile phones, wearable devices, Internet of Things (IoT) devices (including Narrow Band Internet of Things (NB-IoT) and enhanced / massive Machine Type Communication ((e / m)MTC), tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, wireless terminal devices in smart homes, and so on. The embodiments of this application do not limit the specific technologies or device forms used in the terminal devices.

[0061] With the continuous development of wireless communication technology, satellite communication is considered an important aspect of future wireless communication technology development. 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, current standardization discussions have identified the introduction of an offset parameter, Koffset, to compensate for transmission delays. For example... Figure 1b and Figure 1c As shown, Figure 1b This is a schematic diagram of the uplink and downlink time-aligned transmission method on the network device side. Figure 1c This is a schematic diagram of uplink and downlink timing misalignment transmission on the network device side.

[0062] Terminal devices can compensate for transmission delays using ephemeris information and common timing advance (common TA) information. Ephemeris information and common TA information are communicated to the terminal devices via system information.

[0063] The terminal device will consider previously acquired ephemeris and common TA information to be available during the validation duration. The terminal device needs to read system information to obtain the ephemeris and common TA information. The validity period of this information can be directly notified in the system information or bound to the System Information (SI) window.

[0064] However, for some terminal devices (such as Internet of Things (IoT) terminal devices), it may be necessary to merge and receive system information from different SI windows to ensure correct reception of system information. If the effective time of this information is bound to the SI window, then the system information transmitted in different SI windows will be different, and the terminal device will not be able to merge and receive system information from different SI windows.

[0065] It is understood that the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0066] The method and apparatus for obtaining the effective time provided in this application will be described in detail below with reference to the accompanying drawings.

[0067] Please see Figure 2 , Figure 2 This is a flowchart illustrating a method for obtaining the effective time according to an embodiment of this application. It should be noted that the method for obtaining the effective time in 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 2 As shown, the method may include the following steps: Step 201: Receive first indication information sent by the network device, wherein the first indication information is used to indicate the method of obtaining the effective time of the first information.

[0068] In this embodiment of the application, the terminal device can receive first instruction information sent by the network device, and determine the method of obtaining the effective time of the first information according to the instruction of the first instruction information.

[0069] The effective time can be obtained through two methods: the first method and the second method.

[0070] In the embodiments of this application, the first method is an explicit acquisition method, and the second method is an implicit acquisition method.

[0071] Explicit acquisition refers to the terminal device obtaining the effective time by parsing relevant information fields in the system information; that is, the system information explicitly carries the effective time information. Implicit acquisition refers to the terminal device implicitly obtaining the effective time corresponding to the system information by parsing the system information; the system information does not explicitly carry the effective time information.

[0072] In some implementations, the method for obtaining the effective time of the first indication information is a first method (i.e., an explicit acquisition method). The terminal device can receive system information sent by the network device and determine the effective time of the first information based on the signaling carried in the system information.

[0073] In some implementations, the method for obtaining the effective time of the first indication information is a first method (i.e., an explicit acquisition method), and the terminal device can receive the system information in combination through at least one system information SI window.

[0074] It should be noted that merged reception means that if the terminal device fails to correctly receive system information within the first SI window and does not obtain the system information transmitted in the first SI window, it can continue to perform detection in at least one subsequent second SI window, and can merge and decode the system information based on the information received in the first SI window and the information received in the at least one second SI window.

[0075] Understandably, in the case of explicit acquisition, the system information explicitly carries signaling for determining the effective time. Therefore, the system information transmitted by the at least one SI window is the same, so the terminal device can merge and receive the system information transmitted by the at least one SI window.

[0076] In some implementations, the method for obtaining the effective time of the first indication information is a second method (i.e., an implicit acquisition method). The terminal device can receive system information sent by the network device and determine the effective time of the first information based on the end position of the system information window where the system information is located.

[0077] In some implementations, the method for obtaining the effective time of the first indication information is the second method (i.e., the implicit acquisition method), and the terminal device independently receives the system information through each system information window in at least one system information window.

[0078] It should be noted that independent reception means that the terminal device receives system information based on a single SI window. If the terminal device fails to correctly receive the system information in the third SI window and does not receive the system information transmitted in the third SI window, it will restart the detection and reception of system information in the subsequent fourth SI window. If it receives the system information correctly, it will receive the system information transmitted in the fourth SI window; if the terminal device still fails to receive the system information correctly in the fourth SI window, it will restart the detection and reception of system information in the subsequent fifth SI window.

[0079] Understandably, in the case of implicit acquisition, the effective time of the first information is indicated implicitly. For example, the effective time is bound to the SI window, the effective time is determined according to the end position of the SI window, or the effective time is implicitly determined by reusing a certain information field in the system information. Therefore, multiple system information transmitted in different SI windows are different and cannot be merged and received.

[0080] In this embodiment of the application, optionally, the first indication information can be 1 bit information to indicate the method of obtaining the effective time of the first information. As an example, the first indication information being "1" indicates that the method of obtaining the effective time of the first information is the first method (explicit acquisition method), and the first indication information being "0" indicates that the method of obtaining the effective time of the first information is the second method (implicit acquisition method), and so on. It can be understood that the first indication information being "0" indicates that the method of obtaining the effective time of the first information is the first method (explicit acquisition method), the first indication information being "1" indicates that the method of obtaining the effective time of the first information is the second method (implicit acquisition method), and so on.

[0081] In some implementations, the terminal device can also receive second indication information, which is used to indicate the effective time of obtaining the first information using the first method within a first time domain, and / or to indicate the effective time of obtaining the first information using the second method within a second time domain.

[0082] That is, as a first possible implementation, the second indication information is used to indicate the effective time of obtaining the first information using the first method within the first time domain.

[0083] As a second possible implementation, the second indication information is used to indicate the effective time of obtaining the first information using the second method within the second time domain.

[0084] As a third possible implementation, the second indication information is used to indicate the effective time of obtaining the first information using the first method within the first time domain, and the effective time of obtaining the first information using the second method within the second time domain.

[0085] It is understood that, in the embodiments of this application, the terminal device can determine, according to the instructions of the second instruction information, which time domain range to use the explicit acquisition method to obtain the effective time, and which time domain range to use the implicit acquisition method to obtain the effective time.

[0086] Optionally, the second indication information is used to indicate at least one of the following: the start position of the first time domain range, the end position of the first time domain range, the time length of the first time domain range, the start position of the second time domain range, the end position of the second time domain range, and the time length of the second time domain range.

[0087] Optionally, in this embodiment of the application, the first indication information may be included in the first system information block (SIB1).

[0088] Optionally, the first instruction information and the second instruction information can be carried in the same system information or in different system information. The second instruction information can be included in the Master Information Block (MIB) or in other System Information Blocks (SIBx), such as SIB1.

[0089] Optionally, the system information used to obtain the effective time of the first information is other system information besides SIB1.

[0090] Optionally, the first and second indication information may also be carried through other higher-layer signaling (such as Radio Resource Control (RRC) signaling), Medium Access Control (MAC) layer control element (CE, or control unit) MAC CE, or physical layer signaling.

[0091] In this embodiment of the application, the first information may include ephemeris information and common timing advance (TA) information.

[0092] In summary, by receiving the first indication information sent by the network device, wherein the first indication information is used to indicate the method for obtaining the effective time of the first information, and the method of obtaining the effective time includes a first method and a second method, the terminal device can clearly determine the method for obtaining the effective time of the first information according to the indication, flexibly configure the method for obtaining the effective time, effectively improve the efficiency of information transmission, improve the robustness of communication system transmission, and ensure that the network device and the terminal device reach a consistent understanding of the effective time of the updated system information when updating system information.

[0093] Please see Figure 3 , Figure 3 This is a flowchart illustrating a method for obtaining the effective time according to an embodiment of this application. It should be noted that the method for obtaining the effective time in 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 3 As shown, the method may include the following steps: Step 301: Receive first indication information sent by the network device, wherein the first indication information is used to indicate that the method of obtaining the effective time of the first information is a first method.

[0094] In this embodiment of the application, the terminal device can receive first instruction information sent by the network device, and determine the method of obtaining the effective time of the first information according to the instruction of the first instruction information.

[0095] In this embodiment of the application, the effective time indicated by the first indication information is obtained in the first way, that is, the explicit acquisition method.

[0096] The explicit acquisition method refers to the terminal device obtaining the effective time by parsing the relevant information fields in the system information, that is, the effective time information is explicitly carried in the system information.

[0097] In some implementations, the terminal device may also receive a second indication information sent by the network device, which is used to indicate the effective time of obtaining the first information using the first method within a first time domain.

[0098] Optionally, the second indication information is used to indicate at least one of the following: the start position of the first time domain range, the end position of the first time domain range, and the time length of the first time domain range.

[0099] In this embodiment, the terminal device can determine the first time domain range and explicitly obtain the effective time of the first information within that range. The terminal device can also receive system information in a merged manner within that first time domain range. That is, the terminal device can receive system information transmitted through at least one system information window within that first time domain range in a merged manner.

[0100] In this embodiment of the application, the first information may include ephemeris information and common timing advance (TA) information.

[0101] Step 302: Receive system information by merging through at least one system information window.

[0102] In this embodiment, after determining that the acquisition method is explicit acquisition, the terminal device can merge and receive system information transmitted through at least one system information window. This system information carries signaling used to determine the effective time of the first information.

[0103] It is understandable that the system information transmitted in the at least one system information SI window is the same, so the terminal device can merge and receive the system information transmitted in the at least one system information window.

[0104] It should be noted that merged reception means that if the terminal device fails to correctly receive system information within the first SI window and does not obtain the system information transmitted in the first SI window, it can continue to perform detection in at least one subsequent second SI window, and can merge and decode the system information based on the information received in the first SI window and the information received in the at least one second SI window.

[0105] Step 303: Determine the effective time of the first information based on the signaling carried in the system information.

[0106] In this embodiment, the terminal device can receive system information through at least one system information window and determine the effective time of the first information based on the signaling carried in the system information. The signaling carried in the system is used to determine the effective time of the first information, and the network device explicitly notifies the terminal device of the effective time of the first information through the signaling.

[0107] In summary, by receiving first indication information sent by a network device, wherein the first indication information is used to indicate the method of obtaining the effective time of the first information as a first method, and by receiving system information in combination through at least one system information window, and determining the effective time of the first information based on the signaling carried in the system information, the terminal device can clearly understand the method of obtaining the effective time of the first information according to the indication, and flexibly configure the method of obtaining the effective time. This can effectively improve the efficiency of information transmission, improve the robustness of communication system transmission, and ensure that the network device and the terminal device have a consistent understanding of the effective time of the updated system information when updating system information.

[0108] Please see Figure 4 , Figure 4This is a flowchart illustrating a method for obtaining the effective time according to an embodiment of this application. It should be noted that the method for obtaining the effective time in 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: Step 401: Receive first indication information sent by the network device, wherein the first indication information is used to indicate that the method for obtaining the effective time of the first information is the second method.

[0109] In this embodiment of the application, the terminal device can receive first instruction information sent by the network device, and determine the method of obtaining the effective time of the first information according to the instruction of the first instruction information.

[0110] In this embodiment of the application, the effective time indicated by the first indication information is obtained in the second way, that is, the implicit acquisition method.

[0111] Implicit acquisition refers to the terminal device implicitly acquiring the effective time of the system information by parsing the system information, where the effective time information is not explicitly carried in the system information.

[0112] In some implementations, the terminal device may also receive a second indication information sent by the network device, which is used to indicate the effective time of obtaining the first information using the second method within a second time domain.

[0113] Optionally, the second indication information is used to indicate at least one of the following: the start position of the second time domain range, the end position of the second time domain range, and the time length of the second time domain range.

[0114] In this embodiment, the terminal device can determine the second time domain range and implicitly obtain the effective time of the first information within that range. The terminal device can independently receive system information within that second time domain range. That is, the terminal device can independently receive system information transmitted from each system information window within at least one system information window in the first time domain range.

[0115] In this embodiment of the application, the first information may include ephemeris information and common timing advance (TA) information.

[0116] Step 402: Receive system information independently through each system information window in at least one system information window.

[0117] In this embodiment, the terminal device obtains the effective time of the first information implicitly. The terminal device independently receives system information through each SI window in at least one SI window, and then determines the effective time of the first information.

[0118] It should be noted that independent reception means that the terminal device receives system information based on a single SI window. If the terminal device fails to correctly receive the system information in the third SI window and does not receive the system information transmitted in the third SI window, it will restart the detection and reception of system information in the subsequent fourth SI window. If it receives the system information correctly, it will receive the system information transmitted in the fourth SI window; if the terminal device still fails to receive the system information correctly in the fourth SI window, it will restart the detection and reception of system information in the subsequent fifth SI window.

[0119] Understandably, in the case of implicit acquisition, the effective time of the first information is indicated implicitly. For example, the effective time is bound to the SI window, or the effective time is determined according to the end position of the SI window. Therefore, multiple system information transmitted in different SI windows are different and cannot be merged and received.

[0120] Step 403: Determine the effective time of the first information based on the end position of the system information window where the system information is located.

[0121] In this embodiment, the multiple system information transmitted in the at least one SI window does not explicitly carry the signaling determining the effective time of the first information, but rather indicates the effective time of the first information implicitly. The terminal device independently receives system information through the system information window and can determine the effective time of the first information based on the end position of the system information window where the system information is located.

[0122] In summary, by receiving a first indication message sent by a network device, wherein the first indication message indicates that the method for obtaining the effective time of the first information is the second method, and by independently receiving system information through each system information window in at least one system information window, and determining the effective time of the first information based on the end position of the system information window, the terminal device can clearly understand the method for obtaining the effective time of the first information according to the indication, flexibly configure the method for obtaining the effective time, effectively improve the efficiency of information transmission, improve the robustness of communication system transmission, and ensure that the network device and the terminal device have a consistent understanding of the effective time of the updated system information when updating system information.

[0123] Please see Figure 5 , Figure 5 This is a flowchart illustrating a method for obtaining the effective time according to an embodiment of this application. It should be noted that the method for obtaining the effective time in this embodiment is executed by a network device. This method can be executed independently or in conjunction with any other embodiment of this application. Figure 5 As shown, the method may include the following steps: Step 501: Send first indication information to the terminal device, wherein the first indication information is used to indicate the method of obtaining the effective time of the first information.

[0124] In this embodiment of the application, the network device can send first instruction information to the terminal device, and the terminal device can determine the method of obtaining the effective time of the first information according to the instruction of the first instruction information.

[0125] The effective time can be obtained through two methods: the first method and the second method.

[0126] In the embodiments of this application, the first method is an explicit acquisition method, and the second method is an implicit acquisition method.

[0127] Explicit acquisition refers to the terminal device obtaining the effective time by parsing relevant information fields in the system information; that is, the system information explicitly carries the effective time information. Implicit acquisition refers to the terminal device implicitly obtaining the effective time corresponding to the system information by parsing the system information; the system information does not explicitly carry the effective time information.

[0128] In some implementations, the method for obtaining the effective time of the first indication information is a first method (i.e., an explicit acquisition method). The network device can send system information to the terminal device, which carries signaling to determine the effective time of the first information.

[0129] In some implementations, the method for obtaining the effective time of the first indication information is a first method (i.e., an explicit acquisition method). The network device can send system information to the terminal device through at least one system information (SI) window, which is used to receive the system information in a combined manner.

[0130] It should be noted that merged reception means that if the terminal device fails to correctly receive system information within the first SI window and does not obtain the system information transmitted in the first SI window, it can continue to perform detection in at least one subsequent second SI window, and can merge and decode the system information based on the information received in the first SI window and the information received in the at least one second SI window.

[0131] Understandably, in the case of explicit acquisition, the system information explicitly carries signaling for determining the effective time. Therefore, the system information transmitted by the at least one SI window is the same, so the terminal device can merge and receive the system information transmitted by the at least one SI window.

[0132] In some implementations, the method for obtaining the effective time of the first indication information is a second method (i.e., an implicit acquisition method). The network device can send system information to the terminal device, and the end position of the system information window where the system information is located is used to determine the effective time of the first information.

[0133] In some implementations, the method for obtaining the effective time of the first indication information is a second method (i.e., an implicit acquisition method). The network device can send system information to the terminal device through at least one system information (SI) window, which is used to independently receive the system information.

[0134] It should be noted that independent reception means that the terminal device receives system information based on a single SI window. If the terminal device fails to correctly receive the system information in the third SI window and does not receive the system information transmitted in the third SI window, it will restart the detection and reception of system information in the subsequent fourth SI window. If it receives the system information correctly, it will receive the system information transmitted in the fourth SI window; if the terminal device still fails to receive the system information correctly in the fourth SI window, it will restart the detection and reception of system information in the subsequent fifth SI window.

[0135] Understandably, in the case of implicit acquisition, the effective time of the first information is indicated implicitly. For example, the effective time is bound to the SI window, the effective time is determined according to the end position of the SI window, or the effective time is implicitly determined by reusing a certain information field in the system information. Therefore, multiple system information transmitted in different SI windows are different and cannot be merged and received.

[0136] In this embodiment of the application, optionally, the first indication information can be 1 bit information to indicate the method of obtaining the effective time of the first information. As an example, the first indication information being "1" indicates that the method of obtaining the effective time of the first information is the first method (explicit acquisition method), and the first indication information being "0" indicates that the method of obtaining the effective time of the first information is the second method (implicit acquisition method), and so on. It can be understood that the first indication information being "0" indicates that the method of obtaining the effective time of the first information is the first method (explicit acquisition method), the first indication information being "1" indicates that the method of obtaining the effective time of the first information is the second method (implicit acquisition method), and so on.

[0137] In some implementations, the network device can also send a second indication message to the terminal device, the second indication message being used to indicate the effective time of obtaining the first information using the first method within a first time domain, and / or to indicate the effective time of obtaining the first information using the second method within a second time domain.

[0138] That is, as a first possible implementation, the second indication information is used to indicate the effective time of obtaining the first information using the first method within the first time domain.

[0139] As a second possible implementation, the second indication information is used to indicate the effective time of obtaining the first information using the second method within the second time domain.

[0140] As a third possible implementation, the second indication information is used to indicate the effective time of obtaining the first information using the first method within the first time domain, and the effective time of obtaining the first information using the second method within the second time domain.

[0141] It is understood that, in the embodiments of this application, the terminal device can determine, according to the instructions of the second instruction information, which time domain range to use the explicit acquisition method to obtain the effective time, and which time domain range to use the implicit acquisition method to obtain the effective time.

[0142] Optionally, the second indication information is used to indicate at least one of the following: the start position of the first time domain range, the end position of the first time domain range, the time length of the first time domain range, the start position of the second time domain range, the end position of the second time domain range, and the time length of the second time domain range.

[0143] Optionally, in an embodiment of this application, the first system information block SIB1 includes the first indication information.

[0144] Optionally, the first indication information and the second indication information can be in the same system information or in different system information. The second indication information can be included in the main system information block MIB or in other system information blocks SIBx.

[0146] Optionally, the system information used to obtain the effective time of the first information is other system information besides SIB1.

[0147] In this embodiment of the application, the first information may include ephemeris information and common timing advance (TA) information.

[0148] In summary, by sending a first indication message to the terminal device, wherein the first indication message is used to indicate the method for obtaining the effective time of the first information, and the method of obtaining the effective time includes a first method and a second method, the terminal device can clearly specify the method for obtaining the effective time of the first information according to the indication, flexibly configure the method for obtaining the effective time, effectively improve the efficiency of information transmission, improve the robustness of communication system transmission, and ensure that network devices and terminal devices reach a consistent understanding of the effective time of updated system information when updating system information.
