Description

Technical Field

[0001] This disclosure relates to the field of communications, and in particular to data transmission methods and apparatus, and storage media. Background Technology

[0002] In the research of wireless communication technology, satellite communication is considered an important aspect of the future development of wireless communication technology. Satellite communication refers to communication conducted by ground-based radio communication equipment using satellites as relays. A satellite communication system consists of a satellite component and a ground component. The characteristics of satellite communication are: large communication range; communication between any two points within the coverage area of ​​the satellite's emitted radio waves; and low susceptibility to land-based disasters (high reliability). As a supplement to current terrestrial cellular communication systems, satellite communication offers the following advantages: First, it can extend coverage, solving communication problems in areas where current cellular communication systems cannot cover or where coverage costs are high, such as oceans, deserts, and remote mountainous areas. Second, it can facilitate emergency communication; for example, in extreme situations such as disasters like earthquakes where cellular communication infrastructure is unavailable, satellite communication can quickly establish communication connections. Additionally, it can provide industry applications; for example, for long-distance, latency-sensitive services, satellite communication can reduce transmission latency.

[0003] It is foreseeable that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration, truly realizing the Internet of Everything.

[0004] For some terminals, due to limitations in their capabilities, multiple repetitive transmissions or receptions may be required to meet coverage requirements. In satellite communication scenarios, especially when the satellite's transmitted beam is constantly moving, the service time of a single beam is limited, which may lead to interruptions in data transmission at the terminal.

[0081] In this embodiment of the present disclosure, if data transmission with the terminal via the first beam has not ended but the first beam can no longer provide service to the terminal, the first satellite can determine a second beam to continue data transmission with the terminal, thereby switching to the second beam.

[0114] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0115] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0116] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, 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 word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0117] In satellite communication scenarios, especially with moving beams, the service time of a single beam is limited, which may prevent the data transmission required by the terminal from being guaranteed. For example... Figure 1 As shown, the satellite provides service to terminal 1 at time T1, but at time T2, due to satellite movement, it can no longer provide service to terminal 1. If terminal 1 has configured repeated data transmission, including but not limited to repeated data sending and / or repeated data receiving, data transmission interruption will occur.

[0118] To address the aforementioned issues, this disclosure provides various data transmission schemes that can ensure the reliability of data transmission in satellite communication systems.

[0119] It should be noted that the solution provided in this disclosure does not restrict the location of the base station deployment. The base station can be deployed on a satellite to interact with the terminal, or the base station can be deployed on the ground with the satellite acting as a relay to realize the interaction between the base station and the terminal. This disclosure does not limit this.

[0120] It is understandable that, when a base station is deployed on a satellite and switches to a new satellite's beam to continue providing service to the terminal, the base stations interacting with the terminal are different base stations deployed on different satellites. Similarly, when a base station is deployed on the ground and switches to a new satellite's beam to continue providing service to the terminal, the base station interacting with the terminal can also be the same ground-based base station. Of course, other situations should also fall within the scope of this disclosure.

[0121] The first option is to directly switch to the new service beam without notifying the terminal side.

[0122] This disclosure provides a data transmission method, referring to... Figure 2A As shown, Figure 2A This is a flowchart illustrating a data transmission method according to an embodiment, which can be used for a first satellite. The method may include the following steps:

[0123] In step 201, in response to determining that the data transmission with the terminal via the first beam has not ended and that the first beam can no longer provide services to the terminal, a second beam is determined to continue the data transmission with the terminal.

[0124] In this embodiment of the disclosure, the first satellite can determine, based on its own and other satellites' ephemeris information, including but not limited to information such as movement speed and direction, which allows it to provide service to the terminal after the service period for the first beam ends; that is, to determine the second beam. The second beam may be a beam from the first satellite that is different from the first beam, or the second beam may be a beam from a second satellite that is different from the first satellite; this disclosure does not limit this.

[0125] In step 202, the second beam is executed.

[0126] In this embodiment of the disclosure, when the second beam originates from the first satellite, the first satellite can switch the first beam to the second beam and continue data transmission with the terminal via the second beam. For example... Figure 2B As shown, at time T1, satellite 1 provides services to terminal 1 through the first beam. At time T2, the first beam can no longer provide services to terminal 1, so the first satellite switches beams, and the second beam from satellite 1 continues to provide services to terminal 1.

[0127] Alternatively, the first satellite can switch to a second beam from the second satellite, which then continues data transmission with the terminal via the second beam. For example... Figure 2C As shown, at time T1, satellite 1 provides services to terminal 1 through the first beam. At time T2, the first beam of satellite 1 can no longer provide services to terminal 1, and the other beams of satellite 1 can no longer provide services to the terminal. It can switch to the second beam, and satellite 2 can continue to provide services to terminal 1 through the second beam.

[0128] In the above embodiments, if data transmission with the terminal via the first beam has not ended but the first beam can no longer provide service to the terminal, the first satellite can determine a second beam to continue data transmission with the terminal, thereby switching to the second beam. This ensures the reliability of data transmission in the satellite communication system.

[0129] In some alternative embodiments, refer to Figure 3 As shown, Figure 3 This is a flowchart illustrating a data transmission method according to an embodiment, including the following steps:

[0130] In step 301, the data information to be transmitted is sent.

[0131] The data to be transmitted is the data that needs to be transmitted when the second satellite and the terminal continue to transmit data, including but not limited to the data that the second satellite needs to send to the terminal, and / or the data that the terminal needs to upload to the second satellite.

[0132] In this embodiment of the disclosure, if it is necessary for the second beam from the second satellite to continue data transmission with the terminal, the first satellite can send the data information to the second satellite.

[0133] In one example, the first satellite can directly send the data to be transmitted to the second satellite via an inter-satellite link with the second satellite.

[0134] In another example, the first satellite can send the data information to be transmitted to the ground station, which then forwards it to the second satellite.

[0135] The above is merely an illustrative example; other methods of providing data information to be transmitted to a second satellite should also fall within the scope of this disclosure.

[0136] In the above embodiments, the first satellite can provide the second satellite with the data that needs to be transmitted when the second satellite continues to transmit data with the terminal, so that the second satellite can continue to transmit data with the terminal, thus ensuring the reliability of data transmission in the satellite communication system.

[0137] In some alternative embodiments, refer to Figure 4 As shown, Figure 4 This is a flowchart illustrating a data transmission method according to an embodiment, including the following steps:

[0138] In step 401, duration indication information for indicating the duration of data transmission interruption is sent to the terminal.

[0139] In this embodiment of the disclosure, if the original base station determines to switch to the second beam, it will cause a data transmission interruption between the network side and the terminal. If the original base station is located on a satellite, the first satellite sends a duration indication information to the terminal indicating the duration of the data transmission interruption. If the original base station is located on the ground, the duration indication information is relayed to the terminal via the first satellite. The original base station refers to the base station corresponding to the terminal when it transmits data with the first satellite through the first beam.

[0140] The terminal can stop data interaction with the first satellite during the time period indicated by the duration indication information, thus avoiding the waste of terminal resources caused by the terminal continuing to receive or send data during that time period.

[0141] Optionally, in this embodiment of the disclosure, if the original base station determines that the terminal has switched to the second beam before the service period for the first beam to provide services to the terminal ends, it will not cause a data transmission interruption between the network side and the terminal. Accordingly, the duration indication information may not be sent to the terminal.

[0142] In the above embodiments, if it is determined that switching to the second beam will cause a data transmission interruption with the terminal, the first satellite can send duration indication information to the terminal, or the duration indication information can be sent to the terminal via the first satellite relay, thus avoiding the waste of terminal resources caused by the terminal continuing to receive or send data during that time period, and ensuring high availability.

[0143] This disclosure provides a data transmission method, referring to... Figure 5 As shown, Figure 5 This is a flowchart illustrating a data transmission method according to an embodiment, which can be used in a terminal, including but not limited to terminals that support repetitive data transmission, such as NB-IoT (Narrow Band Internet of Things) terminals. The method may include the following steps:

[0144] In step 501, in response to receiving duration indication information indicating the duration of data transmission interruption, data interaction with the first satellite is stopped during the time period indicated by the duration indication information.

[0145] In this embodiment, beam switching is transparent to the terminal, meaning the terminal always considers the network accessible and can send or receive data with the network according to the pre-received base station configuration information or scheduled transmission method. The base station configuration information or scheduled transmission method can be provided by the original base station, which refers to the base station corresponding to the terminal when transmitting data with the first satellite via the first beam.

[0146] In another example, the terminal may also transmit data with the network side based on newly received base station configuration information or a newly scheduled transmission method. This disclosure does not limit this.

[0147] If the original base station determines that switching to the second beam will cause a data transmission interruption with the terminal, it can send a duration indication message to the terminal via the first satellite. During the time period indicated by the duration indication message, the terminal will cease data interaction with the first satellite. Alternatively, the duration indication message can be relayed to the terminal via the first satellite, and the terminal will cease data interaction with the first satellite during that time period.

[0148] In the above embodiments, the terminal can stop data interaction with the first satellite during the time period indicated by the duration indication information, thereby avoiding waste of terminal resources and ensuring high availability.

[0149] In some alternative embodiments, refer to Figure 6 As shown, Figure 6 This is a flowchart illustrating a data transmission method according to an embodiment, which may include the following steps:

[0150] In step 601, in response to determining that the data transmission with the terminal via the first beam has not ended and that the first beam can no longer provide services to the terminal, the first satellite determines a second beam to continue the data transmission with the terminal.

[0151] Wherein, the second beam is a beam from the first satellite that is different from the first beam, or the second beam is a beam from the second satellite.

[0152] In step 602, the first satellite switches the data transmission beam to the second beam.

[0153] In step 603, the first satellite sends duration indication information to the terminal, indicating the duration of the data transmission interruption.

[0154] In this embodiment of the disclosure, the original base station may send the duration indication information to the terminal if it determines that it will cause a data transmission interruption with the terminal.

[0155] In one example, if the original base station is located on a satellite, then the first satellite directly sends the duration indication information to the terminal.

[0156] In another example, the original base station is located on the ground and can transmit duration indication information to the terminal via a first satellite relay.

[0157] In step 604, in response to receiving duration indication information indicating the duration of data transmission interruption, the terminal stops data interaction with the first satellite during the time period indicated by the duration indication information.

[0158] In the above embodiments, the terminal always considers the network side reachable and can transmit data with the network side according to the pre-received base station configuration information or the scheduled transmission method. Alternatively, it can transmit data with the network side based on newly received base station configuration information or a new scheduled transmission method.

[0159] In the above embodiments, when the second beam comes from the second satellite, the first satellite can also transmit data information of the data to be transmitted. Figure 6 (Not shown in the image). The data to be transmitted is the data that needs to be transmitted when the second satellite and the terminal continue data transmission.

[0160] In the above embodiments, if data transmission with the terminal via the first beam has not ended but the first beam can no longer provide service to the terminal, the first satellite can determine a second beam to continue data transmission with the terminal, thereby switching to the second beam. This ensures the reliability of data transmission in the satellite communication system. In addition to the first solution described above, this disclosure also provides a second solution, whereby the satellite informs the terminal of the new serving beam, and the terminal accesses the new serving beam.

[0161] This disclosure provides a data transmission method, referring to... Figure 7 As shown, Figure 7 This is a flowchart illustrating a data transmission method according to an embodiment, which can be used for a first satellite. The method may include the following steps:

[0162] In step 701, in response to determining that the data transmission between the terminal and the first beam has not ended and that the first beam can no longer provide services to the terminal, target indication information is sent to the terminal.

[0163] The target indication information is used to instruct the terminal to access the second beam, which is either a beam from the first satellite and different from the first beam, or a beam from a second satellite. In the above embodiment, the first satellite can send target indication information to the terminal, instructing it to access the second beam to continue data transmission, even if data transmission with the terminal via the first beam has not ended but the first beam can no longer provide service to the terminal. This ensures the reliability of data transmission in the satellite communication system. In this embodiment, the terminal accessing the second beam means that the terminal communicates with network-side equipment via the second beam.

[0164] In some alternative embodiments, refer to Figure 8 As shown, Figure 8 This is a flowchart illustrating a data transmission method according to an embodiment, which may include the following steps:

[0165] In step 801, association information is sent to the terminal.

[0166] In this embodiment of the disclosure, the associated information includes, but is not limited to, at least one of the following: access configuration information for the terminal to access the second beam, first transmission parameters for continuing data transmission after accessing the second beam, and duration indication information for indicating the duration of data transmission interruption.

[0167] In this embodiment of the disclosure, when the original base station is located on the ground, the original base station can send the association information to the first satellite via higher-layer signaling, including but not limited to RRC (Radio Resource Control) signaling and MAC (Media Access Control Address) CE (Control Element) signaling, and the first satellite will then send it to the terminal. Alternatively, the original base station can send the association information to the first satellite via physical layer signaling, and the first satellite will then send it to the terminal. The original base station refers to the base station corresponding to the terminal when it transmits data with the first satellite.

[0168] When the original base station is located on a satellite, the first satellite can send the associated information to the terminal via higher-layer signaling or physical-layer signaling.

[0169] In the above embodiments, the first satellite can send the associated information to the terminal so that the terminal can access the second beam to continue data transmission, which has high availability.

[0175] Reference Figure 9 As shown, Figure 9 This is a flowchart illustrating a data transmission method according to an embodiment, which can be used in a terminal, including but not limited to terminals that support repeated data transmission, such as NB-IoT terminals. The method may include the following steps:

[0176] In step 901, in response to the fact that the data transmission with the first satellite via the first beam has not ended and the target indication information sent by the first satellite is received, the second beam is accessed based on the target indication information.

[0177] In step 902, data transmission continues through the second beam.

[0178] The second beam is a beam from the first satellite and different from the first beam, or the second beam is a beam from the second satellite.

[0179] In the above embodiments, the terminal can access the second beam according to the instructions of the first satellite, thereby continuing data transmission through the second beam. This also ensures the reliability of data transmission in the satellite communication system.

[0184] The first transmission parameters include, but are not limited to, the time-frequency resources and number of transmissions required for the terminal to continue data transmission after connecting to the second beam. The terminal can continue data transmission after connecting to the second beam based on these first transmission parameters.

[0185] Based on the duration indication information, the terminal can stop data interaction with the first satellite and / or complete the process of accessing the second beam, which will be further described in later embodiments.

[0186] In the above embodiments, the terminal can receive the associated information sent by the first satellite and perform corresponding operations, including but not limited to accessing the second beam, continuing data transmission after accessing the second beam, and stopping data interaction with the first satellite. This is simple to implement and highly available.

[0187] In some alternative embodiments, refer to Figure 11 As shown, Figure 11 This is a flowchart illustrating a data transmission method according to an embodiment, which may include the following steps:

[0188] In step 1101, during the time period indicated by the duration indication information, data interaction with the first satellite is stopped.

[0189] In the above embodiments, the terminal can stop data interaction with the first satellite during the time period indicated by the duration indication information, thereby avoiding waste of terminal resources and ensuring high availability.

[0190] In some alternative embodiments, refer to Figure 12 As shown, Figure 12 This is a flowchart illustrating a data transmission method according to an embodiment, which may include the following steps:

[0191] In step 1201, the second beam is accessed during the time period indicated by the duration indication information.

[0192] In this embodiment of the disclosure, the terminal can complete the relevant operations for accessing the second beam based on the access configuration information within the time period indicated by the duration indication information, so as to continue data transmission after the time period ends.

[0193] In the above embodiments, the terminal can access the second beam within the time period indicated by the duration indication information. This ensures the reliability of data transmission in the satellite communication system.

[0194] In some alternative embodiments, refer to Figure 13 As shown, Figure 13 This is a flowchart illustrating a data transmission method according to an embodiment, which may include the following steps:

[0195] In step 1301, the second transmission parameters sent by the second satellite corresponding to the second beam are received.

[0196] In this embodiment of the disclosure, if the second beam comes from a second satellite, the second satellite can send the second transmission parameters to the terminal.

[0197] In step 1302, data transmission continues through the second beam based on the second transmission parameters.

[0198] In the above embodiments, the terminal can continue to transmit data through the second beam according to the second transmission parameters sent by the second satellite, thus ensuring the reliability of data transmission in the satellite communication system.

[0199] In some alternative embodiments, refer to Figure 14 As shown, Figure 14 This is a flowchart illustrating a data transmission method according to an embodiment, which may include the following steps:

[0200] In step 1401, the first satellite, in response to determining that the data transmission with the terminal via the first beam has not ended and that the first beam can no longer provide services to the terminal, sends target indication information to the terminal.

[0201] In step 1402, the first satellite sends association information to the terminal.

[0202] In step 1403, the terminal accesses the second beam within the time period indicated by the duration indication information included in the associated information.

[0203] The second beam is a beam from the first satellite and different from the first beam, or the second beam is a beam from the second satellite.

[0204] In step 1404, the terminal continues to transmit data via the second beam.

[0205] In the above embodiments, if data transmission between the first satellite and the terminal via the first beam has not ended but the first beam can no longer provide service to the terminal, the first satellite can send target indication information to the terminal, instructing the terminal to connect to the second beam. This allows data transmission to continue via the second beam. In the satellite communication system, the reliability of data transmission is also ensured.

[0206] In the two data transmission schemes mentioned above, the terminal needs to continue data transmission through the second beam. In addition to the two data transmission schemes mentioned above, this disclosure also provides a third scheme, which does not require switching to other beams of the same satellite or different WeChat beams to continue data transmission, but allows the terminal to complete data transmission within the target time period.

[0207] Reference Figure 15 As shown, Figure 15 This is a flowchart illustrating a data transmission method according to an embodiment, which can be used for a first satellite. The method may include the following steps:

[0208] In step 1501, in response to determining that data transmission with the terminal cannot be completed within the target time period, updated transmission indication information is determined for the terminal.

[0209] In this embodiment of the disclosure, the target time period refers to the time period during which the terminal is provided with services through the first beam, and the updated transmission indication information is used by the terminal to complete data transmission within the target time period.

[0210] In step 1502, the updated transmission indication information is sent to the terminal.

[0211] In the above embodiments, if the first satellite determines that data transmission with the terminal cannot be completed within the target time period when it provides services to the terminal through the first beam, then the first satellite can determine updated transmission indication information for the terminal and send it to the terminal. Based on the updated transmission indication information, the terminal continues data transmission with the first satellite through the first beam, thereby allowing the terminal to complete data transmission within the target time period without needing to access other beams of the same satellite or beams of different satellites. This also ensures the reliability of data transmission in the satellite communication system.

[0212] In some optional embodiments, the updated transmission indication information includes, but is not limited to, at least one of the following: updated terminal power information, updated resource location information, updated modulation and coding strategy, and updated number of repeated transmissions.

[0213] In one example, the updated terminal power information could indicate a higher terminal power. For instance, if the terminal previously transmitted data using a power value of P1, the updated terminal power information would indicate that the terminal is transmitting data using a power value of P2, where P2 > P1.

[0214] In one example, updated resource location information can indicate more data transmission resource locations for the terminal. For instance, if the terminal previously transmitted data at time-frequency resource locations n1 and n2, the updated resource location information indicates that the terminal can transmit data at time-frequency resources n1, n2, and n3.

[0215] In one example, the updated adjustment coding measurement can instruct the terminal to encode the transmitted data according to a more efficient MCS (Modulation and Coding Scheme).

[0216] In one example, the updated repeat count can indicate fewer repeats. For instance, if the terminal previously had 1000 repeats, the updated repeat count would be 600.

[0217] For example, if the first satellite determines that the transmission duration of a certain data packet repeatedly transmitted by the terminal is 10 minutes, but the target time period for the first satellite to provide services to the terminal through the first beam is less than 10 minutes, the first satellite can determine the updated transmission instruction information for the terminal and send it to the terminal, thereby completing the repeated transmission of the data packet within the target time period.

[0218] In the above embodiments, the first satellite ensures that the terminal can complete data transmission within the target time period by determining the updated transmission indication information, without having to switch to the second beam to continue data transmission. This also ensures the reliability of data transmission in the satellite communication system.

[0219] This disclosure provides a data transmission method, referring to... Figure 16 As shown, Figure 16 This is a flowchart illustrating a data transmission method according to an embodiment, which can be used in a terminal, including but not limited to terminals that support repeated data transmission, such as NB-IoT terminals. The method may include the following steps:

[0220] In step 1601, in response to the fact that the data transmission with the first satellite via the first beam has not ended and an updated transmission indication message is received from the first satellite, data transmission with the first satellite via the first beam continues based on the updated transmission indication message.

[0221] The updated transmission indication information is used by the terminal to complete data transmission within a target time period, where the target time period is the period during which the first satellite provides services to the terminal through the first beam.

[0222] In the above embodiments, the terminal will not continue to transmit data through the second beam, but can complete the data transmission through the first beam within the target time period, which saves network-side resources and ensures the reliability of data transmission in the satellite communication system.

[0223] In some alternative embodiments, the updated transmission indication information includes at least one of the following:

[0224] Updated terminal power information, updated resource location information, updated modulation and coding strategy, and updated number of repeated transmissions.

[0225] In some alternative embodiments, refer to Figure 17 As shown, Figure 17This is a flowchart illustrating a data transmission method according to an embodiment, which may include the following steps:

[0226] In step 1701, the first satellite, in response to determining that data transmission with the terminal cannot be completed within the target time period, determines updated transmission indication information for the terminal.

[0227] The target time period is the time period during which the terminal is provided with services by the first beam, and the updated transmission indication information is used by the terminal to complete data transmission within the target time period.

[0228] In step 1702, the first satellite sends the updated transmission indication information to the terminal.

[0229] In step 1703, the terminal continues to transmit data with the first satellite via the first beam based on the updated transmission indication information.

[0230] In the above embodiments, the terminal will not continue to transmit data through the second beam, but can complete the data transmission through the first beam within the target time period, which saves network-side resources and ensures the reliability of data transmission in the satellite communication system.
