Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to a method and apparatus for determining the effective time. Background Art

[0002] With the continuous development of wireless communication technologies, satellite communication is considered an important aspect of the future development of wireless communication technologies. 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 data transmission delay. For transmissions with an uplink-downlink relationship, the terminal device can compensate for the transmission delay through ephemeris information and relevant information of common TA (Common Timing Advance). The ephemeris information and the information of common TA are notified to the terminal device through system information.

[0003] In the related art, the terminal device considers the previously obtained ephemeris information and common TA information to be available during the validation duration. For the effective time of this information, it can be bound to the SI (System Information) window, that is, the effective time is related to the time domain position of the system information window. However, this may cause some terminal devices to be unable to merge and receive the system information of different SI windows, thereby affecting the reliability of the system reception performance.

Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0110] To better understand a method for determining the effective time disclosed in the embodiments of the present application, a communication system applicable to the embodiments of the present application will be described first below.

[0111] Please refer to Figure 1a , Figure 1a which is a schematic diagram of the architecture of a communication system provided by the embodiments of the present application. 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 the devices shown are for illustration only and do not constitute a limitation on the embodiments of the present application. In practical applications, there may be two or more network devices and two or more terminal devices. Figure 1a The communication system shown takes a network device 101 and a terminal device 102 as an example.

[0112] 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) systems, fifth-generation mobile communication systems, 5G new radio systems, or other future new mobile communication systems, etc.

[0113] The network device 101 in the embodiments of the present application is an entity on the network side 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, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the network device. The network device provided in the embodiments of the present application can be composed of a Central Unit (CU) and a Distributed Unit (DU). Among them, the CU can also be called a Control Unit. Adopting the CU-DU structure can split the protocol layer of the network device, such as a base station. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0114] The terminal device 102 in the embodiments of the present application is an entity on the user side for receiving or transmitting signals, such as a mobile phone. The terminal device can also be called a terminal, a user equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc. The terminal device can be an automobile with communication functions, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver functions, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, and so on. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0115] With the continuous development of wireless communication technology, satellite communication is considered an important aspect of the future development of 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 data transmission delay. For transmissions with an uplink-downlink relationship, in the current standardization discussions, a parameter of offset Koffset is determined to compensate for the transmission delay. As Figure 1b and Figure 1c shown, Figure 1b is a schematic diagram of the uplink-downlink timing alignment transmission mode on the network device side, Figure 1c is a schematic diagram of the uplink-downlink timing misalignment transmission mode on the network device side.

[0116] The terminal device can compensate for the transmission delay through ephemeris information and relevant information of common TA (common timing advance). The ephemeris information and the information of common TA are notified to the terminal device through system information.

[0117] In the related art, the terminal device considers the previously obtained ephemeris information and common TA information to be available during the validation duration. The terminal device needs to read the system information to obtain the ephemeris information and common TA information. The effective time of these information can be bound to the SI (System Information) window.

[0118] However, for some terminal devices (such as IoT (Internet of Things) terminal devices), it may be necessary to merge and receive the system information through different SI windows to ensure the correct reception of the system information. If the effective time of these information is bound to the SI window, then the system information transmitted in different SI windows is different, and the terminal device cannot merge and receive the system information in different SI windows, resulting in an impact on the reliability of the system reception performance.

[0119] It can be understood that the communication system described in the embodiments of the present application is to more clearly illustrate 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 of ordinary skill in the art know that with the evolution of the system architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0120] The method and device for determining the effective time provided by the present application will be introduced in detail below with reference to the accompanying drawings.

[0121] Please refer to Figure 2 , Figure 2It is a schematic flowchart of a method for determining the effective time provided by an embodiment of the present application. It should be noted that the method for determining the effective time in the embodiment of the present application is executed by a terminal device. As Figure 2 shown, the method may include the following steps:

[0122] Step 201, receive system information through at least one system information window within a predefined time domain range.

[0123] In the embodiment of the present application, the terminal device can receive the system information transmitted by at least one system information window within the predefined time domain range in a combined manner. The system information carries a signaling for determining the effective time of the first information.

[0124] It should be noted that combined reception means that if the terminal device fails to complete the detection of the system information within a first SI window within the time domain range and does not obtain the system information, it can continue the detection within at least one subsequent second SI window within the time domain range, and can decode the system information by combining the information received in the first SI window and the information received in the at least one second SI window.

[0125] It can be understood that the system information transmitted by at least one system information SI window within the time domain range is the same, so the terminal device can receive the system information transmitted by the at least one system information window in a combined manner.

[0126] In the embodiment of the present application, at least one SI window not within the time domain range is used to independently receive system information. That is, the terminal device independently receives system information in the SI window not within the time domain range.

[0127] In some embodiments, the terminal device can obtain the configuration information of the time domain range for determining the time domain range. Among them, the configuration information of the time domain range may include at least one of the following: the start position of the time domain range, the length of the time domain range, and the end position of the time domain range. The terminal device can determine the time domain range according to the configuration information of the time domain range.

[0128] Optionally, the configuration information of the time domain range may be defined by a protocol or sent by a network device to the terminal device.

[0129] In some embodiments, the first information may include ephemeris information and common timing advance (common TA) information.

[0130] Step 202, determine the effective time of the first information according to the signaling carried in the system information.

[0131] In an embodiment of the present application, the terminal device can receive system information according to at least one system information window within a time domain range, and determine the effective time of the first information according to the signaling carried in the system information. The signaling carried in the system information 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 this signaling.

[0132] In an embodiment of the present application, in some embodiments, for SI windows not within the time domain range, the terminal device independently receives system information in the SI windows not within the time domain range.

[0133] It should be noted that in an embodiment of the present application, the system information is transmitted in the SI window, which may be a system information block SIB, etc. The system information transmitted in the SI window within the time domain range explicitly carries the signaling for determining the effective time of the first information, while the system information transmitted in the SI window not within the time domain range does not explicitly carry this signaling.

[0134] In summary, by receiving system information according to at least one system information window within a predefined time domain range, and determining the effective time of the first information according to the signaling carried in the system information, the terminal device can not only determine the effective time of the first information, but also merge and receive the system information in different system information windows, effectively improving the efficiency of information transmission and the accuracy of information reception, enhancing the robustness of the communication system transmission, and ensuring that the network device and the terminal device reach a consistent understanding of the effective time of the updated system information in the case of updating the system information.

[0135] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a method for determining the effective time provided by an embodiment of the present application. It should be noted that the method for determining the effective time in an embodiment of the present application is executed by the terminal device. As Figure 3 shown, the method may include the following steps:

[0136] Step 301, determine the time domain range according to the configuration information of the time domain range.

[0137] In an embodiment of the present application, the terminal device can determine the configuration information of the time domain range according to the indication of the network device or according to the pre - defined regulations in the protocol, and determine the time domain range according to this configuration information.

[0138] Among them, the configuration information of the time domain range may include at least one of the following: the starting position of the time domain range; the length of the time domain range; the ending position of the time domain range.

[0139] In some embodiments, the terminal device receives the Primary Synchronization Signal (PSS) and / or the Secondary Synchronization Signal (SSS) sent by the network device, and the terminal device can determine the configuration information of the time domain range according to the PSS and / or the SSS.

[0140] Optionally, as a first possible embodiment, the terminal device determines the configuration information of the time domain range based on the sequence information of the PSS according to a preset rule.

[0141] As a second possible embodiment, the terminal device determines the configuration information of the time domain range based on the sequence information of the SSS according to a preset rule.

[0142] As a third possible embodiment, the terminal device determines the configuration information of the time domain range based on the sequence information of the PSS and the SSS according to a preset rule.

[0143] Optionally, as a first possible embodiment, the terminal device can determine the configuration information of the time domain range based on the transmission position information of the PSS.

[0144] As a second possible embodiment, the terminal device can determine the configuration information of the time domain range based on the transmission position information of the SSS.

[0145] As a third possible embodiment, the terminal device can determine the configuration information of the time domain range based on the transmission position information of the PSS and the SSS.

[0146] In some embodiments, the terminal device can also determine the configuration information of the time domain range by receiving a second signaling sent by the network device. The second signaling sent by the network device can be carried on system information such as the Master Information Block (MIB) of the master system information block, or other system information blocks (SIBx), or can also be carried on other high-layer signaling such as Radio Resource Control (RRC) signaling, Media Access Control Layer Control Element (MACCE), or physical layer signaling, etc.

[0147] In some embodiments, the terminal device may also determine the configuration information of the time domain range according to a manner predefined in the protocol. For example, the configuration information of the time domain range is specified in the protocol, and the terminal device directly determines the configuration information of the time domain range according to the protocol provisions.

[0148] In the embodiments of the present application, the terminal device can determine the time domain range according to the configuration information of the time domain range. The terminal device can determine the position of the time domain range and can receive the system information in a merged manner when it is within the time domain range. That is, further, the terminal device can receive the system information transmitted in at least one system information window within the time domain range in a merged manner.

[0149] Step 302, monitor at least one system information window.

[0150] In the embodiments of the present application, the terminal device can monitor at least one SI window to receive system information through the at least one SI window.

[0151] After the terminal device monitors at least one SI window, it can determine whether the at least one SI window is within the time domain range.

[0152] Step 303, when the at least one system information window is within the time domain range, receive the system information through the at least one system information window.

[0153] In the embodiments of the present application, after the terminal device determines the time domain range, it can receive the system information transmitted in at least one system information window within the time domain range in a merged manner. The system information carries a signaling for determining the effective time of the first information.

[0154] It can be understood that the system information transmitted in at least one system information SI window within the time domain range is the same, so the terminal device can receive the system information transmitted in the at least one system information window in a merged manner.

[0155] It should be noted that merged reception means that if the terminal device fails to complete the detection of the system information in a first SI window within the time domain range and does not obtain the first system information, it can continue the detection in at least one subsequent second SI window within the time domain range, and can merge and decode to obtain the system information according to the information received in the first SI window and the information received in the at least one second SI window.

[0156] In some embodiments, the first information may include ephemeris information and common timing advance (common TA) information.

[0157] Step 304, determine the effective time of the first information according to the signaling carried in the system information.

[0158] In an embodiment of the present application, the terminal device can receive system information by merging at least one system information window in the time domain, and determine the effective time of the first information according to the signaling carried in the system information. The signaling carried in the system information 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 this signaling.

[0159] Step 305, when the at least one system information window is not within the time domain, receive system information independently through each system information window.

[0160] In an embodiment of the present application, for the system information transmitted by at least one SI window not within the time domain, the terminal device independently receives the system information based on a single SI window not within the time domain, and then determines the effective time of the first information according to the system information.

[0161] It should be noted that, in an embodiment of the present application, for the system information transmitted by at least one SI window not within the time domain, the terminal device does not perform merged reception, but receives the system information based on a single SI window. If the terminal device fails to complete the detection of the system information in a third SI window not within the time domain and does not obtain the system information transmitted by the third SI window, in a subsequent fourth SI window not within the time domain, it restarts the detection and reception of the system information. If the detection is completed and the system information transmitted in the fourth SI window is obtained; if the terminal device still fails to complete the detection in the fourth SI window, it will restart the detection and reception of the system information in a subsequent fifth SI window not within the time domain.

[0162] In addition, it should be noted that the multiple system information transmitted in at least one SI window not within the time domain does not explicitly carry the signaling for determining the effective time of the first information, but indicates the effective time of the first information in an implicit manner. For example, the effective time is bound to the SI window. Therefore, there are differences in the multiple system information transmitted in at least one SI window not within the time domain.

[0163] Step 306, determine the effective time of the first information according to the system information.

[0164] In an embodiment of the present application, the multiple system information transmitted in at least one SI window not within the time domain does not explicitly carry the signaling for determining the effective time of the first information, but indicates the effective time of the first information in an implicit manner.

[0165] As an example, the effective time of the first information is bound to the SI window for transmitting the system information, and the terminal device can determine the effective time of the first information according to the time-domain position of the SI window. Alternatively, some information fields in the system information can be reused, and the effective time of the first information can be determined through the reused information fields, and so on. It can be understood that the system information can also implicitly indicate the effective time of the first information in other ways, which is not limited here.

[0166] In summary, according to the configuration information of the time domain range, determine the time domain range, monitor at least one system information window, the at least one system information window is within the time domain range, receive system information through the at least one system information window, and determine the effective time of the first information according to the signaling carried in the system information. If the at least one system information window is not within the time domain range, receive system information independently through each system information window, and determine the effective time of the first information according to the system information, so that while the terminal device determines the effective time of the first information, it can also merge and receive the system information in different system information windows, effectively improving the efficiency of information transmission and the accuracy of information reception, improving the robustness of communication system transmission, and ensuring that the network device and the terminal device reach a consistent understanding of the effective time of the updated system information in the case of updating the system information.

[0167] Please refer to Figure 4 , Figure 4 is a schematic flowchart of a method for determining the effective time provided by an embodiment of the present application. It should be noted that the method for determining the effective time in the embodiment of the present application is executed by the network device. As Figure 4 shown, the method may include the following steps:

[0168] Step 401, send system information to the terminal device in at least one system information window within a predefined time domain range, and the signaling carried in the system information is used to determine the effective time of the first information.

[0169] In the embodiment of the present application, the network device sends system information to the terminal device in at least one system information window within a predefined time domain range, and the signaling carried in the system information is used to determine the effective time of the first information. This enables the terminal device to merge and receive the system information transmitted by at least one system information window within the time domain range to obtain the system information.

[0170] It can be understood that the system information transmitted by at least one system information SI window within the time domain range is the same, so the terminal device can merge and receive the system information transmitted by the at least one system information window.

[0171] It should be noted that merged reception means that if the terminal device fails to complete the detection of system information and obtain the system information within a first SI window in this time domain range, it can continue the detection within at least one subsequent second SI window in this time domain range, and can merge and decode to obtain the system information according to the information received in the first SI window and the information received in the at least one second SI window.

[0172] In some embodiments, the network device also sends configuration information of the time domain range to the terminal device, and the configuration information of the time domain range is used to determine this time domain range. Among them, the configuration information of the time domain range includes at least one of the following: the start position of the time domain range, the length of the time domain range, and the end position of the time domain range. The terminal device can determine this time domain range according to the configuration information of the time domain range.

[0173] Optionally, the configuration information of the time domain range may also be defined by the protocol.

[0174] In some embodiments, the first information may include ephemeris information and common timing advance (common TA) information.

[0175] In the embodiments of this application, in some embodiments, the network device sends system information to the terminal device in at least one system information window not within this time domain range, and the at least one system information window not within this time domain range is used to independently receive system information.

[0176] In the embodiments of this application, the system information transmitted in the SI window not within the time domain range does not explicitly carry the signaling indicating the effective time of the first information, but implicitly indicates the effective time of the first information. Therefore, the system information transmitted in multiple system information windows not within this time domain range is different. The terminal device can independently receive the system information based on a single SI window not within this time domain range, and can determine the effective time of the first information according to this system information.

[0177] It should be noted that in the embodiments of this application, the system information is transmitted in the SI window, and it may be a system information block (SIB), etc.

[0178] In summary, by sending system information to the terminal device in at least one system information window within a predefined time domain range, the signaling carried in this system information is used to determine the effective time of the first information, so that while the terminal device determines the effective time of the first information, it can also perform merged reception of the system information in different system information windows, effectively improving the efficiency of information transmission and the accuracy of information reception, improving the robustness of communication system transmission, and also ensuring that the network device and the terminal device reach a consistent understanding of the effective time of the updated system information in the case of updating the system information.

[0179] Please refer to Figure 5 , Figure 5 which is a schematic flowchart of a method for determining the effective time provided by an embodiment of this application. It should be noted that the method for determining the effective time in the embodiment of this application is executed by a network device. As Figure 5 shown, the method may include the following steps:

[0180] Step 501: Send configuration information of the time domain range to the terminal device, where the configuration information of the time domain range is used to determine the time domain range.

[0181] In the embodiment of this application, the network device sends the configuration information of the time domain range to the terminal device, and this configuration information is used to determine the time domain range.

[0182] Among them, the configuration information of the time domain range includes at least one of the following: the starting position of the time domain range; the length of the time domain range; the ending position of the time domain range.

[0183] In some embodiments, the network device sends the primary synchronization signal PSS and / or the secondary synchronization signal SSS to the terminal device, and the PSS and / or SSS are used to determine the configuration information of the time domain range.

[0184] Optionally, as a first possible embodiment, the sequence information of the PSS is used to determine the configuration information of the time domain range. The terminal device can determine the configuration information of the time domain range based on the sequence information of the PSS according to a preset rule.

[0185] As a second possible embodiment, the sequence information of the SSS is used to determine the configuration information of the time domain range. The terminal device can determine the configuration information of the time domain range based on the sequence information of the SSS according to a preset rule.

[0186] As a third possible embodiment, the sequence information of the PSS and SSS is used to determine the configuration information of the time domain range. The terminal device can determine the configuration information of the time domain range based on the sequence information of the PSS and SSS according to a preset rule.

[0187] Optionally, as a first possible embodiment, the transmission position information of the PSS is used to determine the configuration information of the time domain range. The terminal device can determine the configuration information of the time domain range based on the transmission position information of the PSS.

[0188] As a second possible embodiment, the transmission position information of the SSS is used to determine the configuration information of the time domain range. The terminal device can determine the configuration information of the time domain range based on the transmission position information of the SSS.

[0189] As a third possible implementation, the transmission location information of the PSS and the SSS is used to determine the configuration information of the time domain range. The terminal device can determine the configuration information of the time domain range based on the transmission location information of the PSS and the SSS.

[0190] In some embodiments, the terminal device can also determine the configuration information of the time domain range by receiving a second signaling sent by the network device. The second signaling sent by the network device can be carried on system information such as the master system information block MIB, or other system information blocks SIBx, or can also be carried on other high-layer signaling such as radio resource control RRC (Radio Resource Control) signaling, media access control layer control element MACCE (Media Access Control Layer, MAC, media access control layer, Control Element, CE, control element, or control unit), or physical layer signaling, etc.

[0191] In some embodiments, the network device and the terminal device can also determine the configuration information of the time domain range according to a predefined manner in the protocol. For example, the configuration information of the time domain range is specified in the protocol, and the network device and the terminal device can directly determine the configuration information of the time domain range according to the protocol provisions.

[0192] Step 502: Send system information to the terminal device in at least one system information window within the time domain range. The signaling carried in the system information is used to determine the effective time of the first information.

[0193] In the embodiments of the present application, the network device sends system information to the terminal device in at least one system information window within a predefined time domain range. The system information carries signaling, and the signaling is used to determine the effective time of the first information. This enables the terminal device to perform combined reception of the system information transmitted in at least one system information window within the time domain range.

[0194] It can be understood that the system information transmitted in at least one system information SI window within the time domain range is the same, so the terminal device can perform combined reception of the system information transmitted in the at least one system information window.

[0195] It should be noted that combined reception means that if the terminal device fails to complete the detection of system information and does not obtain the first system information in a first SI window within the time domain range, it can continue to detect in at least one subsequent second SI window within the time domain range, and can perform combined decoding to obtain the system information according to the information received in the first SI window and the information received in the at least one second SI window.

[0196] Step 503: Transmit system information to the terminal device in at least one system information window that is not within the time domain range.

[0197] Among them, at least one system information window that is not within the time domain range is used to independently receive system information.

[0198] In the embodiment of the present application, the system information transmitted in the SI window that is not within the time domain range does not explicitly carry the signaling indicating the effective time of the first information, but implicitly indicates the effective time of the first information. Therefore, the system information transmitted in multiple system information windows that are not within the time domain range is different. The terminal device can independently receive the system information based on a single SI window that is not within the time domain range, and can determine the effective time of the first information according to the system information.

[0199] It should be noted that in the embodiment of the present application, the system information is transmitted in the SI window, which may be a system information block SIB, etc. The system information transmitted in the SI window within the time domain range explicitly carries the signaling for determining the effective time of the first information, while the system information transmitted in the SI window not within the time domain range does not explicitly carry this signaling.

[0200] In summary, by transmitting the configuration information of the time domain range to the terminal device, the configuration information of the time domain range is used to determine the time domain range. In at least one system information window within the time domain range, system information is transmitted to the terminal device, and the signaling carried in the system information is used to determine the effective time of the first information. In at least one system information window that is not within the time domain range, system information is transmitted to the terminal device, so that while the terminal device determines the effective time of the first information, it can also merge and receive the system information in different system information windows, effectively improving the efficiency of information transmission and the accuracy of information reception, improving the robustness of the communication system transmission, and ensuring that the network device and the terminal device reach a consistent understanding of the effective time of the updated system information in the case of updating the system information.
