Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method and device for determining an effective time. Background Art

[0002] With the continuous development of wireless communication technology, satellite communication is considered to be 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 transmitter and the receiver, data transmission has a large delay. For transmission with uplink and downlink relationship, the terminal device can compensate for the transmission delay through the ephemeris information and commonTA (common timing advance) related information. The ephemeris information and common TA information are notified to the terminal device through system information.

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

[0110] In order to better understand a method for determining an effective time disclosed in an embodiment of the present application, the communication system to which the embodiment of the present application is applicable is first described below.

[0111] See also Figure 1a , Figure 1a The present invention 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 the devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of the present application. In actual applications, two or more network devices and two or more terminal devices may be included. Figure 1a The communication system shown includes 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, such as Long Term Evolution (LTE) system, fifth generation mobile communication system, 5G new air interface system, or other future new mobile communication systems.

[0113] The network device 101 in the embodiment of the present application is an entity on the network side for transmitting or receiving signals. For example, the network device 101 and may be an evolved NodeB (eNB), a transmission point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device. The network device provided in the embodiment of the present application may be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit (Control Unit). The CU-DU structure may be used to split the protocol layer of the network device, such as the base station, and the functions of some protocol layers are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0114] The terminal device 102 in the embodiment of the present application is an entity for receiving or transmitting signals on the user side, such as a mobile phone. The terminal device may also be referred to as a terminal device (terminal), a user equipment (UE), a mobile station (MS), a mobile terminal device (MT), etc. The terminal device may be a car with communication function, a smart car, a mobile phone (Mobile Phone), a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (Virtual Reality, VR) terminal device, an augmented reality (Augmented Reality, AR) terminal device, a wireless terminal device in industrial control (Industrial Control), a wireless terminal device in self-driving (Self-Driving), a wireless terminal device in remote surgery (Remote Medical Surgery), a wireless terminal device in smart grid (Smart Grid), a wireless terminal device in transportation safety (Transportation Safety), a wireless terminal device in smart city (Smart City), a wireless terminal device in smart home (Smart Home), etc. The embodiment of the present application does not limit the specific technology and specific device form adopted by the terminal device.

[0115] With the continuous development of wireless communication technology, satellite communication is considered to be 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 transmitter and the receiver, data transmission has a large delay. For transmission with uplink and downlink relationships, the current standardization discussion has determined the introduction of offset Koffset parameters to compensate for transmission delay. Figure 1b and Figure 1c As shown, Figure 1b This is a schematic diagram of the uplink and downlink timing alignment transmission mode on the network device side. Figure 1c This is a schematic diagram of the transmission mode with misaligned uplink and downlink timing on the network device side.

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

[0117] In the related art, the terminal device considers the previously acquired ephemeris information and common TA information to be available within the validation duration. The terminal device needs to read the system information to obtain the ephemeris information and common TA information. The validity period of this information may 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 combine 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, the system information transmitted in different SI windows is different, and the terminal device cannot combine and receive system information from different SI windows, which affects the reliability of system reception performance.

[0119] It can be understood that the communication system described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0120] The method and device for determining the effective time provided by the present application are described in detail below in conjunction with the accompanying drawings.

[0121] See also Figure 2 , Figure 21 is a flow chart of a method for determining an effective time provided in an embodiment of the present application. It should be noted that the method for determining an effective time in an embodiment of the present application is executed by a terminal device. Figure 2 As shown, the method may include the following steps:

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

[0123] In an embodiment of the present application, the terminal device can receive, in a predefined time domain, system information transmitted by at least one system information window within the time domain, 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 system information within a first SI window within the time domain range and fails to obtain the system information, it can continue to detect within at least one subsequent second SI window within the time domain range, and can combine and decode the information received in the first SI window and the information received in the at least one second SI window to obtain the system information.

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

[0126] In the embodiment of the present application, at least one SI window that is 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 that is not within the time domain range.

[0127] In some implementations, the terminal device can obtain configuration information of the time domain range for determining the time domain range. The configuration information of the time domain range may include at least one of the following: a starting position of the time domain range, a length of the time domain range, and an 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 may be sent by a network device to a terminal device.

[0129] In some implementations, 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 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 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.

[0132] In an embodiment of the present application, in some implementation methods, for an SI window that is not within the time domain range, the terminal device independently receives system information in the SI window that is not within the time domain range.

[0133] 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 explicitly carries a signaling for determining the effective time of the first information, while the system information transmitted in the SI window not within the time domain does not explicitly carry the signaling.

[0134] In summary, system information is received through at least one system information window within a predefined time domain range, and the effective time of the first information is determined according to the signaling carried in the system information. This allows the terminal device to combine and receive system information in different system information windows while determining the effective time of the first information, thereby effectively improving the efficiency of information transmission and the accuracy of information reception, and improving the robustness of communication system transmission. When updating system information, it can also ensure that the network device and the terminal device reach a consistent understanding of the effective time of the updated system information.

[0135] See also Figure 3 , Figure 3 1 is a flow chart of a method for determining an effective time provided in an embodiment of the present application. It should be noted that the method for determining an effective time in an embodiment of the present application is executed by a terminal device. Figure 3 As 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 instructions of the network device or according to the pre-defined provisions in the protocol, and determine the time domain range according to the configuration information.

[0138] 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; and the ending position of the time domain range.

[0139] In some implementations, a terminal device receives a primary synchronization signal PSS (Primary Synchronization Signal) and / or a secondary synchronization signal SSS (Secondary Synchronization Signal) sent by a network device, and the terminal device can determine configuration information of the time domain range based on the PSS and / or SSS.

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

[0143] Optionally, as a first possible implementation, the terminal device may determine the configuration information of the time domain range based on the sending location information of the PSS.

[0144] As a second possible implementation, the terminal device may determine the configuration information of the time domain range based on the sending location information of the SSS.

[0145] As a third possible implementation, the terminal device may determine the configuration information of the time domain range based on the sending 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 main system information block MIB (Master Information Block) or other system information blocks SIBx (System Information Block), or can be carried on other high-level 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, ControlElement, CE, control element, or control unit) or physical layer signaling, etc.

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

[0148] In an embodiment 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 location of the time domain range and can receive the system information in the time domain range. That is, further, the terminal device can receive the system information transmitted by at least one system information window in the time domain range in a combined manner.

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

[0150] In an embodiment of the present application, the terminal device is capable of monitoring at least one SI window to receive system information through the at least one SI window.

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

[0152] Step 303: The at least one system information window is within the time domain range, and system information is received through the at least one system information window.

[0153] In the embodiment of the present application, after determining the time domain range, the terminal device can receive the system information transmitted by at least one system information window within the time domain range in a combined 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 by at least one system information SI window within the time domain is the same, so the terminal device can combine and receive the system information transmitted by the at least one system information window.

[0155] It should be noted that combined reception means that if the terminal device fails to complete the detection of system information within a first SI window within the time domain range and fails to obtain the first system information, it can continue to detect within at least one subsequent second SI window within the time domain range, and can combine and decode the information received in the first SI window and the information received in the at least one second SI window to obtain the system information.

[0156] In some implementations, 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 determine the effective time of the first information according to the signaling carried in the system information by merging and receiving the system information in at least one system information window within the time domain. 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.

[0159] Step 305: The at least one system information window is not within the time domain, and system information is independently received through each system information window.

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

[0161] It should be noted that in the embodiment of the present application, for the system information transmitted by at least one SI window that is not within the time domain range, the terminal device does not perform combined 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 that is not within the time domain range, and fails to obtain the system information transmitted by the third SI window, it restarts the detection and reception of the system information in a subsequent fourth SI window that is not within the time domain range. If the detection is completed, 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 restarts the detection and reception of the system information in a subsequent fifth SI window that is not within the time domain range.

[0162] It should also be noted that the multiple system information transmitted in at least one SI window that is not within the time domain range does not explicitly carry the signaling for determining the effective time of the first information, but instead indicates the effective time of the first information in an implicit manner, such as the effective time is bound to the SI window. Therefore, there are differences among the multiple system information transmitted in at least one SI window that is not within the time domain range.

[0163] Step 306: Determine the effective time of the first information according to the system information.

[0164] In an embodiment of the present application, multiple system information transmitted in at least one SI window that is not within the time domain range does not explicitly carry the signaling for determining the effective time of the first information, but instead 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, the time domain range is determined, and at least one system information window is monitored. The at least one system information window is within the time domain range, and system information is received through the at least one system information window. According to the signaling carried in the system information, the effective time of the first information is determined. The at least one system information window is not within the time domain range, and system information is independently received through each system information window. According to the system information, the effective time of the first information is determined, so that the terminal device can combine and receive system information in different system information windows while determining the effective time of the first information, effectively improving the efficiency of information transmission and the accuracy of information reception, and improving the robustness of communication system transmission. When the system information is updated, it can also ensure that the network device and the terminal device reach a consistent understanding of the effective time of the updated system information.

[0167] See also Figure 4 , Figure 4 1 is a flow chart of a method for determining the effective time provided in 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 a network device. Figure 4 As shown, the method may include the following steps:

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

[0169] In an embodiment of the present application, a network device sends system information to a terminal device in at least one system information window within a predefined time domain, and the system information carries a signaling, which is used to determine the effective time of the first information, so that the terminal device can combine and receive the system information transmitted by at least one system information window within the time domain 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 is the same, so the terminal device can combine and receive the system information transmitted by the at least one system information window.

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

[0172] In some implementations, the network device further 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 the time domain range. The configuration information of the time domain range includes at least one of the following: a starting position of the time domain range, a length of the time domain range, and an 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.

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

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

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

[0176] In an embodiment of the present application, the system information transmitted by the SI window that is not within the time domain does not explicitly carry the signaling indicating the effective time of the first information, but implicitly indicates the effective time of the first information, so there are differences in the system information transmitted by multiple system information windows that are not within the time domain. The terminal device can independently receive and obtain system information based on a single SI window that is not within the time domain, and can determine the effective time of the first information based on the system information.

[0177] 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.

[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 the system information is used to determine the effective time of the first information, so that the terminal device can combine and receive the system information in different system information windows while determining the effective time of the first information, thereby effectively improving the efficiency of information transmission and the accuracy of information reception, and improving the robustness of the communication system transmission. In the case of updating the system information, it can also ensure that the network device and the terminal device reach a consistent understanding of the effective time of the updated system information.

[0179] See also Figure 5 , Figure 5 1 is a flow chart of a method for determining the effective time provided in 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 a network device. Figure 5 As shown, the method may include the following steps:

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

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

[0182] 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; and the ending position of the time domain range.

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

[0184] Optionally, as a first possible implementation, 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 implementation, 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 implementation, 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 implementation, the sending location 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 sending location information of the PSS.

[0188] As a second possible implementation, the sending location 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 sending location information of the SSS.

[0189] As a third possible implementation, the transmission position 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 position 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 main system information block MIB, or other system information blocks SIBx, or can be carried on other high-level 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 method predefined in the protocol. For example, if the configuration information of the time domain range is specified in the protocol, the network device and the terminal device can directly determine the configuration information of the time domain range according to the protocol.

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

[0193] In an embodiment of the present application, a network device sends system information to a terminal device in at least one system information window within a predefined time domain, and the system information carries a signaling used to determine the effective time of the first information, so that the terminal device can combine and receive the system information transmitted by at least one system information window within the time domain.

[0194] It can be understood that the system information transmitted by at least one system information SI window within the time domain is the same, so the terminal device can combine and receive the system information transmitted by 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 within a first SI window within the time domain range and fails to obtain the first system information, it can continue to detect within at least one subsequent second SI window within the time domain range, and can combine and decode the information received in the first SI window and the information received in the at least one second SI window to obtain the system information.

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

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

[0198] In an embodiment of the present application, the system information transmitted by the SI window that is not within the time domain does not explicitly carry the signaling indicating the effective time of the first information, but implicitly indicates the effective time of the first information, so there are differences in the system information transmitted by multiple system information windows that are not within the time domain. The terminal device can independently receive and obtain system information based on a single SI window that is not within the time domain, and can determine the effective time of the first information based on 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 explicitly carries a signaling for determining the effective time of the first information, while the system information transmitted in the SI window not within the time domain does not explicitly carry the signaling.

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