[0039] This disclosure provides an information processing method, apparatus, device, system, storage medium, and program product to ensure the reliability of system information SI transmission, improve network service quality and reliability, and meet the high requirements of modern communication systems for speed, efficiency, and security.
[0040] In a first aspect, embodiments of this disclosure provide an information processing method executed by a network device, the method comprising:
[0041] Based on the downlink time period, send system information SI to the terminal device;
[0042] The downlink time slot is used to transmit downlink data based on the Internet of Things-Non-Ground Network (IoT-NTN).
[0043] In this embodiment of the disclosure, in the IoT-NTN scenario, it can ensure that the network device can send SI to the terminal device during the downlink time period used to transmit downlink data based on IoT-NTN, thereby ensuring the reliability of SI transmission, enabling the terminal device to quickly obtain the necessary information, thereby performing data processing and response faster, improving network service quality and reliability, and meeting the high requirements of modern communication systems for speed, efficiency and security.
[0044] In conjunction with some embodiments of the first aspect, in some embodiments, the SI includes a narrowband system information block 1 SIB1-NB, and the starting frame for transmitting the SIB1-NB is located in the downlink time period.
[0045] In this embodiment of the disclosure, the SIB1-NB contains key system information. By aligning the transmission start frame of the SIB1-NB with the downlink time period, it can be ensured that the terminal device can receive the necessary SI within the expected time window, which helps to coordinate the communication between the network and the terminal device and improve the reliability of communication.
[0046] In conjunction with some embodiments of the first aspect, in some embodiments, sending SI to the terminal device according to the downlink time period includes:
[0047] SIB1-NB is sent during N consecutive downlink time periods.
[0048] In this embodiment of the disclosure, by sending SIB1-NB in multiple consecutive downlink time periods, the chances of the terminal device successfully receiving information are increased, thereby improving the success rate and efficiency of the terminal device accessing the network.
[0049] In conjunction with some embodiments of the first aspect, in some embodiments, the value of N is 8.
[0050] In this embodiment of the disclosure, by sending SIB1-NB in eight consecutive downlink time periods, the network can significantly improve the reliability and efficiency of information transmission. This strategy not only optimizes the information transmission process, but also enhances the system's adaptability in complex and dynamic environments, meeting the high requirements of modern communication systems for stability, flexibility, and user experience.
[0051] In conjunction with some embodiments of the first aspect, in some embodiments, the start frame is configured by the network device.
[0052] In this embodiment of the disclosure, by configuring the start frame, the network device can manage spectrum resources more effectively, avoid conflicts and interference, and ensure efficient transmission of downlink data and SI. Furthermore, by optimizing the start frame configuration, the terminal device can receive system information within the expected time window, reducing waiting time and improving reception efficiency. Moreover, the network device can dynamically adjust the start frame according to current network conditions, load, and environmental changes. This flexibility allows the network to optimize resource allocation in different scenarios, improve overall network performance, and enhance the reliability of SI transmission.
[0053] In conjunction with some embodiments of the first aspect, in some embodiments, the starting frame is configured based on the Narrowband Master Information Block (MIB-NB).
[0054] In this embodiment, the MIB-NB typically contains key system parameters and configuration information. Configuring the start frame based on the MIB-NB ensures that the SIB1-NB's configuration remains consistent with the entire network, enhancing synchronization between the network and terminal devices. Furthermore, the MIB-NB is usually updated and adjusted according to network conditions, and configuring the start frame based on it allows the SIB1-NB's transmission to dynamically adapt to changes in the network environment.
[0055] In conjunction with some embodiments of the first aspect, in some embodiments, the start frame is configured in at least one of the following ways:
[0056] Configure the system frame number (SFN) corresponding to the start frame;
[0057] Configure the offset of the starting frame relative to the 0th system frame.
[0058] In this embodiment of the disclosure, by configuring the offset value of the SFN or the 0th frame of the system frame, the network device can precisely control the transmission time of the SIB1-NB. This precision helps to ensure that the terminal device receives system information within the expected time window, thereby improving the reliability of communication.
[0059] In conjunction with some embodiments of the first aspect, in some embodiments, SI includes a first SI, which is transmitted within a first SI window;
[0060] Based on the downlink time period, send an SI to the terminal device, including at least one of the following:
[0061] If the transmission time of the first SI is not within the downlink time period, the first SI is discarded;
[0062] If the transmission time of the first SI is not within the downlink time period, the first SI is delayed until the downlink time period is reached;
[0063] If the transmission time of the first SI conflicts with the transmission time of the repeated transmission of the first SI, the first SI is discarded;
[0064] If the transmission time of the first SI conflicts with the repetition transmission time of the first SI, and the first SI occupies a first number of subframes, the first SI is transmitted.
[0065] If the transmission time of the first SI conflicts with the retransmission time of the first SI, and the first SI occupies the second number of subframes, the first SI is discarded.
[0066] If the transmission of the first SI requires a second number of subframes, discard the portion of the first SI that was not fully transmitted within a downlink time period.
[0067] In this embodiment of the disclosure, by flexibly handling the transmission of SI, the network can achieve a balance between resource utilization, transmission efficiency, and reliability, thereby enhancing system adaptability and user experience. This strategy not only improves the overall performance of the network but also provides greater flexibility for different application scenarios.
[0068] For example, by discarding SIs that are not in the downlink time period, unnecessary transmission attempts are avoided, network resources are saved, and overall transmission efficiency is improved;
[0069] When the transmission time of SI does not match the downlink time period, choosing delayed transmission instead of immediate transmission can make better use of the downlink time period window and optimize resource allocation.
[0070] When transmission time conflicts occur, channel interference and resource conflicts can be reduced by discarding or adjusting transmission strategies, ensuring that the transmission of other critical data is not affected. This also reduces transmission failures due to conflicts or insufficient resources, improving network stability and quality of service.
[0071] Furthermore, the decision to discard or transmit based on the number of subframes occupied by SI allows for flexible adaptation to different network conditions and requirements, thus optimizing transmission strategies.
[0072] In conjunction with some embodiments of the first aspect, in some embodiments, SI includes a second SI and a third SI, wherein the second SI is transmitted in a second SI window and the third SI is transmitted in a third SI window;
[0073] Based on the downlink time period, send an SI to the terminal device, including at least one of the following:
[0074] If the transmission time of the second SI is delayed until the first downlink time period, and the first downlink time period is not within the window of the second SI, the transmission of the second SI is discarded or stopped.
[0075] If the transmission time of the second SI is delayed to the second downlink time period, and the second downlink time period conflicts with the third SI window, the transmission of the third SI shall be discarded or stopped.
[0076] If the transmission time of the third SI is delayed to the third downlink time period, the third downlink time period conflicts with the third SI window, and both the second SI and the third SI occupy the first number of subframes, the second SI and the third SI are transmitted in the third SI window.
[0077] If the transmission time of the second SI is delayed to the fourth downlink time period, and the fourth downlink time period is not within any SI window, the second SI is transmitted during the fourth downlink time period.
[0078] In this embodiment of the disclosure, by flexibly handling the transmission time and window conflicts between the second SI and the third SI, the network device can achieve a balance between resource utilization, transmission efficiency and reliability, enhance the adaptability of the system and the user experience, thereby improving the overall performance of the network.
[0079] By choosing to discard, stop sending, or adjust the transmission time under different circumstances, network resources can be better utilized, and unnecessary transmission attempts and resource waste can be avoided.
[0080] When SI window conflicts occur, channel interference and resource conflicts are reduced by dropping or stopping the transmission of certain SIs, ensuring that the transmission of other important data is not affected.
[0081] In the event of a conflict, SIs are selectively sent within the SI window to ensure efficient use of resources and improve transmission efficiency.
[0082] If the transmission time of the second SI is delayed until the fourth downlink time period, and the fourth downlink time period does not fall within any SI window, the second SI will be transmitted during the fourth downlink time period. By optimizing the SI transmission strategy, it can be ensured that users can receive important system information in a timely manner, thus improving the user experience.
[0083] In conjunction with some embodiments of the first aspect, in some embodiments, the first quantity is 2;
[0084] The second number is 8.
[0085] In this embodiment of the disclosure, by specifying the number of subframes occupied by the SI, the network device can manage and allocate resources more precisely. A first SI with a quantity of 2 occupies fewer resources and can be transmitted more flexibly within a limited time window, while a second SI with a quantity of 8 occupies more resources and requires a larger time window. In the event of a conflict, prioritizing the transmission of SIs occupying fewer subframes (the first quantity of 2) can improve transmission efficiency and ensure that more SIs can be successfully transmitted with limited resources.
[0086] Secondly, embodiments of this disclosure propose an information processing method, executed by a terminal device, the method comprising:
[0087] Receive system information SI sent by network devices according to the downlink time period;
[0088] The downlink time slot is used to transmit downlink data based on the Internet of Things-Non-Ground Network (IoT-NTN).
[0089] In this embodiment of the disclosure, in the IoT-NTN scenario, it can be ensured that the terminal device can receive the SI sent by the network device during the downlink time period used to transmit downlink data based on IoT-NTN, thereby ensuring the reliability of SI transmission, enabling the terminal device to quickly obtain the necessary information, thereby performing data processing and response faster, improving network service quality and reliability, and meeting the high requirements of modern communication systems for speed, efficiency and security.
[0090] In conjunction with some embodiments of the second aspect, in some embodiments, the SI includes a narrowband system information block 1 SIB1-NB, and the starting frame for transmitting the SIB1-NB is located in the downlink time period.
[0091] In some embodiments, receiving system information SI sent by the network device according to a downlink time period includes:
[0092] Receive SIB1-NB during N consecutive downlink time periods.
[0093] In conjunction with some embodiments of the second aspect, in some embodiments, the value of N is 8.
[0094] In conjunction with some embodiments of the second aspect, in some embodiments, the start frame is configured by the network device.
[0095] In conjunction with some embodiments of the second aspect, in some embodiments, the starting frame is configured based on the Narrowband Master Information Block (MIB-NB).
[0096] In conjunction with some embodiments of the second aspect, in some embodiments, the start frame is configured in at least one of the following ways:
[0097] Configure the system frame number (SFN) corresponding to the start frame;
[0098] Configure the offset of the starting frame relative to the 0th frame in the system frames.
[0099] In conjunction with some embodiments of the second aspect, in some embodiments, SI includes a first SI, which is transmitted within a first SI window;
[0100] The SI sent by the receiving network device according to the downlink time period includes at least one of the following:
[0101] If the transmission time of the first SI is not within the downlink time period, the first SI will not be received;
[0102] If the transmission time of the first SI is not within the downlink time period, the first SI will be received during the downlink time period.
[0103] If the transmission time of the first SI conflicts with the transmission time of the repeated transmission of the first SI, the first SI will not be received;
[0104] If the transmission time of the first SI conflicts with the repetition transmission time of the first SI, and the first SI occupies a first number of subframes, the first SI is received.
[0105] If the transmission time of the first SI conflicts with the repetition transmission time of the first SI, and the first SI occupies the second number of subframes, the first SI will not be received.
[0106] If the transmission of the first SI requires a second number of subframes, the portion of the first SI that was not completely transmitted within a downlink time period will not be received.
[0107] In this embodiment of the disclosure, by managing the reception of SI according to the downlink time period and subframe occupancy, the terminal device can achieve a balance between resource utilization, reception efficiency and reliability, thereby enhancing the system's adaptability and user experience.
[0108] By not receiving SI at inappropriate times, terminal devices can avoid unnecessary resource consumption and optimize the use of their energy and processing resources.
[0109] When the SI transmission time does not match the downlink time period, choosing to delay reception or not receive can improve reception efficiency and ensure that the terminal device receives information within the appropriate time window.
[0110] When transmission time conflicts occur, by not receiving conflicting SIs, terminal devices can reduce channel interference and resource conflicts, ensuring that the reception of other important data is not affected.
[0111] Not receiving SIs when unnecessary can reduce the power consumption of terminal devices.
[0112] In conjunction with some embodiments of the second aspect, in some embodiments, SI includes a second SI and a third SI, wherein the second SI is transmitted in a second SI window and the third SI is transmitted in a third SI window;
[0113] The SI sent by the receiving network device according to the downlink time period includes at least one of the following:
[0114] If the transmission time of the second SI is delayed to the first downlink time period, and the first downlink time period is not within the window of the second SI, the second SI will not be received.
[0115] If the transmission time of the second SI is delayed to the second downlink time period, and the second downlink time period conflicts with the third SI window, the second SI will not be received.
[0116] If the transmission time of the third SI is delayed to the third downlink time period, the third downlink time period conflicts with the third SI window, and both the second SI and the third SI occupy the first number of subframes, the second SI and the third SI are received within the third SI window.
[0117] If the transmission time of the second SI is delayed to the fourth downlink time period, and the fourth downlink time period is not within any SI SI window, the second SI is received during the fourth downlink time period.
[0118] In this embodiment of the disclosure, by managing the reception of the second SI and the third SI according to the downlink time period and subframe occupancy, the terminal device can achieve a balance between resource utilization, reception efficiency and reliability, thereby enhancing the system's adaptability and user experience.
[0119] By not receiving SI at inappropriate times, terminal devices can avoid unnecessary resource consumption and ensure that resources are used for more important or suitable transmissions.
[0120] When a conflict occurs in the SI window, by not receiving the conflicting SI, the terminal device can reduce channel interference and resource conflicts, ensuring that the reception of other important data is not affected.
[0121] Whether to receive depends on the number of subframes occupied by the SI. For example, when the number of subframes occupied by the SI is small (e.g., the first number is 2), it can be received flexibly within a limited time window.
[0122] In case of conflict, selectively receiving SIs within appropriate time windows ensures effective resource utilization and improves reception efficiency.
[0123] In conjunction with some embodiments of the second aspect, in some embodiments, the first quantity is 2;
[0124] The second number is 8.

[0166] First, some of the terms used in the embodiments of this disclosure will be explained:
[0167] System Information (SI)
[0168] Non-terrestrial Network (NTN);
[0169] Next-generation radio access network (NG-RAN);
[0170] User-to-User (Uu)
[0171] Remote Radio Unit (RRU);
[0172] Core Network (CN);
[0173] New Radio (NR);
[0174] Satellite Radio Interface (SRI);
[0175] System Information Block Type 1 for Narrowband (SIB1-NB);
[0176] Internet of Things Non-Terrestrial Network (IoT-NTN);
[0177] Public Land Mobile Network (PLMN);
[0178] Time Division Duplex (TDD);
[0179] Frequency Division Duplexing (FDD);
[0180] System Frame Number (SFN);
[0181] Hyper Frame Number (HFN);
[0182] Narrowband Master Information Block (MIB-NB).
[0183] In modern communication systems, NTN technology can be used for communication, which can provide wireless resources through satellites (or drones) instead of ground base stations.
[0184] Figure 1a is an exemplary schematic diagram of an NTN network architecture provided according to an embodiment of the present disclosure. As shown in Figure 1a, the NTN network architecture includes a terminal device 1101, a satellite 1102, and an NTN gateway station 1103 (or NTN ground station). The terminal device can provide wireless resources via satellite (or drone) instead of a ground base station. Depending on the method by which the satellite processes the signal, this NTN network architecture can be divided into a transparent transmission mode and a regenerative mode.
[0185] Figure 1b is an exemplary schematic diagram of an NTN network architecture in transparent mode according to an embodiment of the present disclosure. As shown in Figure 1b, the NTN network architecture includes an RRU and a network device 1203 (i.e., a base station gNB) in the NG-RAN. The RRU may include a satellite 1202 and an NTN gateway station (or NTN ground station). The network device can access the CN based on a radio access technology standard, for example, the radio access technology standard can be the 5G radio access technology standard NR. The terminal device 1201 (i.e., UE) and the network device 1203 can communicate based on a radio interface (e.g., a UU interface); the network device 1203 is connected to the core network through the NG interface.
[0186] In the NTN network architecture shown in Figure 1b, the NTN gateway station transmits the signal from network device 1203 (e.g., a base station (gNodeB, gNB)) to satellite 1202. Satellite 1202 converts the signal to the satellite frequency band and then transmits it to terminal device 1201 via the satellite frequency band. In transparent transmission mode, satellite 1202 can perform frequency conversion and signal amplification of the signal from network device 1203 without demodulating the signal from network device 1203, similar to a repeater.
[0187] Figure 1c is an exemplary schematic diagram of an NTN network architecture in regenerative mode according to an embodiment of the present disclosure. As shown in Figure 1c, the NTN network architecture includes satellite 1302 and an NTN gateway station (or NTN ground station) in the NG-RAN, and the feeder link between the NTN gateway station and satellite 1302 is implemented through SRI.
[0188] In the NTN network architecture shown in Figure 1c, the NTN gateway station is responsible for communicating with the satellite and forwarding the received, processed signals to the gNB. After the NTN gateway station sends the signal from network device 1302 to the satellite, the satellite demodulates and decodes the signal and then re-encodes and modulates it (this process is called regeneration) to obtain the regenerated signal, which is then transmitted via the satellite frequency band. In regeneration mode, the gNB connects to terminal device 1301 (i.e., UE) via the Uu interface and to the core network via the NG interface. The gNB may need to process signals from ground stations to meet the requirements of the terrestrial network.
[0189] In some embodiments, the NTN network architecture can be used for data transmission in IoT-NTN scenarios. Specifically, during the NTN's TDD cycle, time slots are allocated for IoT-NTN mode, within which the NTN network architecture processes IoT-NTN-based data. Aside from the time slots reserved for IoT-NTN mode, the remaining time is used to support the existing Iridium communication system.
[0190] Through this time slot division, the NTN network architecture can simultaneously support traditional communication services and IoT-NTN services.
[0191] In some embodiments, some time slots of the Iridium communication system are used for IoT-NTN transmission, thus making the Iridium communication system compatible with IoT-NTN;
[0192] In some embodiments, within a 90ms cycle of the Iridium communication system, there is only one downlink time slot and one uplink time slot for IoT NTN transmission;
[0193] In some embodiments, since the Iridium communication system is a TDD system, if some time slots of the Iridium communication system are used for IoT-NTN transmission, then the IoT NTN will be in TDD mode.
[0194] In some embodiments, when the IoT NTN is in TDD mode, the FDD frame structure of the IoT NTN is still used.
[0195] SI refers to a set of important information broadcast by the network to the UE, which is crucial for the UE to correctly access and use the network. The inventors discovered that for IoT NTN in TDD mode compatible with Iridium communication systems, which uses an FDD frame structure, not every radio frame is used for IoT-NTN service transmission. Therefore, when the network device sends SI to the terminal device, the SI may fall on a non-IoT-NTN time or into a radio frame transmitted in a non-IoT NTN, meaning that downlink data cannot be transmitted at that time.
[0196] In some embodiments, the terms "wireless frame" can be used interchangeably with "system frame," "frame," "SFN," "system frame number," "frame number," etc.
[0197] To address the aforementioned issues, this disclosure provides an information processing method, apparatus, device, system, storage medium, and program product. A network device sends System Information (SI) to a terminal device according to a downlink time period; wherein the downlink time period is used to transmit downlink data based on the Internet of Things-Non-Terrestrial Network (IoT-NTN). In this disclosure, in an IoT-NTN scenario, it ensures that the network device can send SI to the terminal device within the downlink time period used for transmitting IoT-NTN-based downlink data, thereby ensuring the reliability of SI transmission. This enables the terminal device to quickly obtain necessary information, thereby processing and responding more quickly, improving network service quality and reliability, and meeting the high requirements of modern communication systems for speed, efficiency, and security.

[0207] The information processing methods, apparatus, equipment, systems, storage media, and program products provided in this disclosure will now be described in detail with reference to the accompanying drawings.
[0208] Figure 2a is an exemplary interactive schematic diagram of an information processing method provided according to an embodiment of the present disclosure. As shown in Figure 2a, the information processing method includes the following steps:
[0209] In step S2101, the network device determines the start frame to be sent for SIB1-NB.
[0210] In some embodiments, SIB1-NB is narrowband system information block 1.
[0211] In some embodiments, the start frame for sending SIB1-NB is the first start frame that the network device sends to the terminal device.
[0212] In some embodiments, the start frame for sending the SIB1-NB is the start frame for the terminal device to begin receiving the SIB1-NB.
[0213] In some embodiments, the start frame is used to indicate the first frame of the data stream transmitting downlink data when the network device sends downlink data to the terminal device.
[0214] In some embodiments, the name of the “starting frame” is not limited. For example, “starting frame” can be used interchangeably with terms such as “beginning frame”, “first frame”, “initial frame”, “header frame”, and “starting frame”.
[0215] In some embodiments, SIB1-NB is used to indicate basic system information of the network.
[0216] In some embodiments, SIB1-NB includes, but is not limited to, at least one of the following:
[0217] 1. Broadcast basic system information, used by terminal devices to determine how to access the network; among which, broadcast basic system information typically includes cell identifier, access parameters, scheduling information, etc.
[0218] 2. Scheduling information, for example, SIB1-NB may include scheduling information of other system information blocks (such as SIB2-NB, etc.), so that the terminal device can know when and how to obtain other necessary SIs.
[0219] 3. Cell selection and reselection parameters are used by terminal devices to select appropriate cells for connection when moving or stationary.
[0220] 4. PLMN information is used by terminal devices to identify and select a suitable network for connection.
[0221] 5. Random access procedure parameters, used for the initial or re-accession of the terminal device to the network. These parameters include, but are not limited to, cell identifiers, access parameters, and scheduling information.
[0222] In some embodiments, the start frame for transmitting SIB1-NB is located within the downlink time period for transmitting downlink data of IoT-NTN.
[0223] In some embodiments, TDD technology is used in NTN to support communication of IoT devices.
[0224] In some embodiments, the current NTN / Iridium system uses the 1616-1626.5MHz spectrum. Please refer to Figure 2b, which is a schematic diagram of the NTN spectrum according to an embodiment of this disclosure. As shown in Figure 2b, within a 90-millisecond (ms) period of the Iridium system, downlink and uplink time periods are allocated specifically for IoT-NTN mode, during which data is transmitted or received using IoT NTN (e.g., NB-IoT NTN technology).
[0225] In some embodiments, the name of "downlink time period" is not limited. Here, "time period" can be replaced by terms such as "time slot", "time", "period", "transmission time", "interval", "duration", "time window", "window", "duration", etc.; "downlink" can be replaced by terms such as "downlink", "downlink transmission", "downlink channel", "receiving link", "gNB to UE direction", "DL", "Downlink".
[0226] In some embodiments, the name of "uplink time period" is not limited. Here, "time period" can be replaced by terms such as "time slot", "time", "segment", "transmission time", "interval", "duration", "time window", "window", "duration", etc.; "uplink" can be replaced by terms such as "uplink", "uplink transmission", "uplink channel", "transmission link", "UE to gNB direction", "UL", "Uplink".
[0227] In some embodiments, apart from the uplink and downlink time slots reserved for IoT-NTN mode, other uplink and downlink time slots in the Iridium system's cycle continue to be used to support existing Iridium communication. This time division enables the Iridium communication system to simultaneously provide Iridium communication services and IoT-NTN communication services.
[0228] In some embodiments, each cycle may include one or more downlink time periods for transmitting IoT-NTN-based downlink data. Alternatively, each cycle may include one or more uplink time periods for transmitting IoT-NTN-based uplink data.
[0229] In some embodiments, the period is one Iridium satellite communication cycle, for example, 90 ms.
[0230] In some embodiments, the number of downlink time periods and uplink time periods in the same period can be the same. For example, each period may include one downlink time period and one uplink time period.
[0231] In some embodiments, the number of downlink time periods and uplink time periods in the same period can be different. For example, a period may include two downlink time periods and one uplink time period.
[0232] In some embodiments, since the Iridium communication system is a TDD system, some time slots of the Iridium communication system will be used for IoT-NTN transmission, and the IoT NTN will be in TDD mode. However, for IoT NTN systems in TDD mode, the FDD frame structure of IoT NTN is still used.
[0233] In some embodiments, since the TDD mode IoT NTN uses the FDD frame structure of IoT NTN, and for the FDD frame structure, each radio frame / system frame can be used for uplink and downlink transmission.
[0234] In some implementations, because TDD-mode IoT NTN uses the FDD frame structure of IoT NTN, not every system frame is used for downlink transmission in TDD-mode IoT-NTN. Instead, each downlink time period can occupy multiple consecutive system frames. For example, each downlink time period can occupy two consecutive system frames; that is, for TDD-mode IoT NT, downlink data based on IoT-NTN is transmitted through two consecutive system frames.
[0235] In some embodiments, each uplink time period is a first duration;
[0236] In some embodiments, each downlink time period is a second duration;
[0237] In some embodiments, the interval between adjacent uplink time periods and downlink time periods is a third duration.
[0238] It should be understood that the dimensions of the first and second durations are not limited in this embodiment. The uplink and downlink durations can be the same or different. Optionally, taking the example where the uplink and downlink durations are the same, the first duration can be 8 milliseconds; the second duration can also be 8 milliseconds. That is, 8 milliseconds are allocated to downlink and uplink transmissions in one cycle, where uplink and downlink transmissions use the same frequency channel for simultaneous transmission.
[0239] In some embodiments, the size of the third duration is not limited in this disclosure; for example, the third duration can be 50 milliseconds.
[0240] In some embodiments, taking the frame structure of IoT NTN's FDD as an example, each downlink time period in IoT NTN TDD mode uses two consecutive system frames. The subframes occupied by the downlink time period in the two consecutive system frames are specifically: 3, 4, 5, 6, 7, 8, 9, 0 (a total of 8ms). Subframes 3, 4, 5, 6, 7, 8, and 9 are subframes in the first system frame occupied by the downlink time period, and 0 is a subframe in the second system frame occupied by the downlink time period. Please refer to Figure 2c, which is a schematic diagram of a TDD frame structure provided according to an embodiment of this disclosure. That is, as shown in Figure 2c, the downlink time periods in this figure include: DL#1, DL#2…DL#113, DL#114, DL#115…
[0241] Among them, the radio frames occupied by DL#1 are SFN=0 and SFN=1 in HFN=0 (DL#1 specifically occupies subframes 3, 4, 5, 6, 7, 8, and 9 in SFN=0, and subframe 0 in SFN=1);
[0242] The radio frames occupied by DL#2 are SFN=9 and SFN=10 in HFN=0 (DL#2 specifically occupies subframes 3, 4, 5, 6, 7, 8, and 9 in SFN=9, and subframe 0 in SFN=10);
[0243] The radio frames occupied by DL#113 are SFN=1017 and SFN=1018 in HFN=0 (DL#113 specifically occupies subframes 3, 4, 5, 6, 7, 8, and 9 in SFN=1017, and subframe 0 in SFN=1018);
[0244] The radio frames occupied by DL#114 are SFN=2 and SFN=3 in HFN=1 (DL#114 specifically occupies subframes 3, 4, 5, 6, 7, 8, and 9 in SFN=2, and subframe 0 in SFN=3);
[0245] The radio frames occupied by DL#115 are SFN=11 and SFN=12 in HFN=1 (DL#115 specifically occupies subframes 3, 4, 5, 6, 7, 8, and 9 in SFN=11, and subframe 0 in SFN=12).
[0246] It should be noted that the allocation method for uplink time periods used to transmit IoT-NTN-based uplink data is similar to that for downlink time periods, and will not be elaborated here.
[0247] In some embodiments, taking a cycle comprising one downlink time period and one uplink time period as an example, the interval between every two downlink time periods is the length of the cycle. For example, taking a cycle length of 90ms as an example, the interval between every two consecutive downlink time periods is 90ms. For example, the time interval between DL#2 and DL#1 is 90 milliseconds; the time interval between DL#14 and DL#13 is 90 milliseconds; the time interval between DL#115 and DL#114 is 90 milliseconds.
[0248] In some embodiments, the starting frame for transmitting SIB1-NB can be any frame in the downlink time period. For example, the starting frame for transmitting SIB1-NB can be any one of SFN=0, SFN=1, SFN=9, SFN=10...SFN=1017, SFN=1018 in HFN=0; or any one of SFN=2, SFN=3, SFN=11, SFN=12 in HFN=1.
[0249] In some embodiments, the start frame for sending SIB1-NB is configured by the network device.
[0250] In some embodiments, the network device may also configure the start frame of the SIB1-NB for the terminal device through the MIB-NB, so that the terminal device can accurately receive the SI based on the start frame of the SIB1-NB.
[0251] In some embodiments, the start frame for transmitting the SIB1-NB is based on the MIB-NB configuration. Optionally, the MIB-NB includes scheduling information, wherein the scheduling information is used to indicate the start frame of the SIB1-NB. The scheduling information may include the SFN corresponding to the start frame, and / or the offset value of the start frame relative to the i-th frame. It should be understood that the i-th frame is not limited in this embodiment; for example, the i-th frame can be any frame such as frame 0 (SFN=0), frame 1 (SFN=0), etc.
[0252] In some embodiments, the starting frame for transmitting the SIB1-NB is a frame within a downlink time period based on IoT-NTN.
[0253] In some embodiments, the configuration methods for sending the start frame of SIB1-NB include, but are not limited to, the following two:
[0254] Method 1: Configure the SFN corresponding to the start frame; for example, configure the system frame number of the start frame to 1, which is used to send the first frame of the start frame of SIB1-NB (i.e., SFN=1).
[0255] Method 2: Configure the offset value of the starting frame relative to the i-th frame of the system frame. It should be understood that the i-th frame is not limited in this embodiment; for example, the i-th frame can be any frame such as frame 0 (SFN=0) or frame 1 (SFN=0). For example, taking frame 0 (SFN=0) as the i-th frame, if the offset value is configured to 2, then the starting frame is the frame with an offset value of 2 relative to frame 0 (SFN=0), that is, the starting frame used to transmit SIB1-NB is the second frame in the period (SFN=2).
[0256] In step S2102, the network device sends SIB1-NB to the terminal device according to the start frame.
[0257] In some embodiments, SI includes SIB1-NB, and the start frame for transmitting SIB1-NB is located in the downlink time period, which is used to transmit downlink data based on IoT-NTN.
[0258] In some embodiments, the network device may send SIB1-NB in N consecutive downlink time periods.
[0259] In some embodiments, the specific value of N is not limited in this disclosure. N can be any value greater than or equal to 1. For example, the value of N can be 8, meaning there are 8 downlink time periods for transmitting SIB1-NB, and SIB1-NB is transmitted in 8 consecutive downlink time periods; or, the value of N can be 16, meaning there are 16 downlink time periods for transmitting SIB1-NB, and SIB1-NB is transmitted in 16 consecutive downlink time periods.
[0260] In this embodiment of the disclosure, by sending SIB1-NB in 8 or 16 consecutive downlink time periods, the network can significantly improve the reliability and efficiency of information transmission. This strategy not only optimizes the information transmission process, but also enhances the system's adaptability in complex and dynamic environments, meeting the high requirements of modern communication systems for stability, flexibility and user experience.
[0261] In this embodiment of the disclosure, by sending SIB1-NB in eight consecutive downlink time periods, the network can significantly improve the reliability and efficiency of information transmission. This strategy not only optimizes the information transmission process, but also enhances the system's adaptability in complex and dynamic environments, meeting the high requirements of modern communication systems for stability, flexibility, and user experience.
[0262] Please continue to refer to Figure 2c. As shown in Figure 2c, the downlink time period includes DL#1 to DL#115... Among them, N consecutive downlink time periods can be any 8 consecutive downlink time periods, for example, DL#1 to DL#8.
[0263] Step S2103: The network device sends the first SI to the terminal device.
[0264] In some embodiments, network devices use scheduling information provided in the SIB1-NB to transmit SI messages within periodically occurring time-domain windows (referred to as SI windows). Each SI message is associated with an SI window, and the SI windows for different SI messages do not overlap; that is, only the corresponding SI message is transmitted within an SI window. The length of the SI window is the same for all SI messages and is configurable.
[0265] In some embodiments, the SI includes a first SI. The first SI is transmitted within the first SI window.
[0266] In some embodiments, since the SI window may contain non-DL time slots, this may cause delays in the transmission of system messages. These delays may cause the transmission of system messages to conflict with the next repetition of the system message, or overlap with other system information windows, thereby leading to reduced message transmission efficiency or transmission failure. In embodiments of this disclosure, when the network device sends the first SI to the terminal device, it includes, but is not limited to, at least one of the following operations:
[0267] 1. If the transmission time of the first SI is not within the downlink time period, the network device discards the first SI.
[0268] Accordingly, if the transmission time of the first SI is not within the downlink time period, the terminal device will not receive the first SI. Specifically, if the transmission time of the first SI is not within the downlink time period used for transmitting downlink data based on IoT-NTN, the network device will not send the first SI. Please refer to Figure 2c. As shown in Figure 2c, if the transmission time of the first SI is at SFN=2, since SFN=2 is not within the downlink time period used for transmitting downlink data based on IoT-NTN, the network device will discard the first SI.
[0269] 2. If the transmission time of the first SI is not within the downlink time period, the network device delays sending the first SI until the downlink time period.
[0270] Accordingly, if the terminal device receives the first SI during a period not earlier than the downlink time period, the reception of the first SI is delayed until the downlink time period begins. For example,
[0271] Specifically, if the transmission time of the first SI is not within the downlink time period used for transmitting downlink data based on IoT-NTN, the first SI is delayed until the downlink time period is reached. Referring to Figure 2c, if the transmission time of the first SI is at SFN=2, since SFN=2 is not within the downlink time period used for transmitting downlink data based on IoT-NTN, the first SI is delayed until the nearest downlink time period is reached. For example, the first SI can be sent to the terminal device at DL#2 (i.e., SFN=9 and SFN=10). Correspondingly, the terminal device receives the first SI at DL#2 (i.e., SFN=9 and SFN=10).
[0272] 3. If the transmission time of the first SI conflicts with the transmission time of the repeated transmission of the first SI, the network device discards the first SI.
[0273] Accordingly, if the transmission time of the first SI conflicts with the transmission time of the repeated transmission of the first SI, the terminal device will not receive the first SI.
[0274] In some embodiments, a conflict between the transmission time of the first SI and the transmission time of its repeated transmissions refers to a situation where, within the first SI window, the transmission time of the first SI overlaps or interferes with the transmission time of its repeated transmissions, causing the terminal device to potentially fail to receive all the necessary information correctly. In this case, the network device may choose not to send the first SI.
[0275] 4. When the transmission time of the first SI conflicts with the repetition transmission time of the first SI, and the first SI occupies the first number of subframes, the network device sends the first SI.
[0276] It should be noted that within an SI window, the corresponding SI message can be repeatedly transmitted multiple times in 2 or 8 consecutive NB-IoT downlink subframes, depending on the Transport Block Size (TBS). The terminal device can obtain detailed time-domain / frequency-domain scheduling information and other information, such as the transmission format for SI messages, from the schedulingInfoList field in SIB1-NB. Therefore, the terminal device does not need to accumulate multiple SI messages in parallel, but may need to accumulate a single SI message across multiple SI windows based on coverage conditions.
[0277] If the transmission time of the first SI overlaps or interferes with the transmission time of the repeated transmission of the first SI within the first SI window, and the first SI occupies a first number of subframes, then the first SI is transmitted within the first SI window.
[0278] Accordingly, if the transmission time of the first SI conflicts with the repetition transmission time of the first SI, and the first SI occupies a first number of subframes, the terminal device receives the first SI within the first SI window.
[0279] It should be understood that the size of the first quantity is not limited in this embodiment. Optionally, the first quantity can be 2. That is, if the transmission time of the first SI overlaps or interferes with the transmission time of the repeated transmission of the first SI in the first SI window, and the first SI occupies 2 subframes, the first SI is transmitted in the first SI window.
[0280] 5. If the transmission time of the first SI conflicts with the retransmission time of the first SI, and the first SI occupies the second number of subframes, the network device discards the first SI.
[0281] Correspondingly, if the transmission time of the first SI conflicts with the repetition transmission time of the first SI, and the first SI occupies the second number of subframes, the terminal device will not receive the first SI.
[0282] It should be understood that the size of the first quantity is not limited in this embodiment. Optionally, the second quantity can be 8. That is, if the transmission time of the first SI overlaps or interferes with the transmission time of the repeated transmission of the first SI within the first SI window, and the first SI occupies 8 subframes, the network device will not send the first SI.
[0283] 6. If the transmission of the first SI requires a second number of subframes, the network device discards the portion of the first SI that was not fully transmitted within a downlink time period.
[0284] Correspondingly, if the transmission of the first SI requires a second number of subframes, the terminal device will not receive the portion of the first SI that has not been completely transmitted within a downlink time period.
[0285] In some embodiments, the second number can be 8. Since a single downlink time period cannot fully transmit the SI occupying the second number of subframes, if the first SI occupies 8 subframes, the network device can discard the portion of the first SI that was not fully transmitted in the downlink time period and only transmit the portion of the first SI that can be transmitted within a single downlink time period.
[0286] In step S2104, the network device sends the second SI and the third SI to the terminal device.
[0287] In some embodiments, SI includes a second SI and a third SI. The second SI is transmitted within a second SI window, and the third SI is transmitted within a third SI window.
[0288] In some embodiments, when the network device sends the second SI and the third SI to the terminal device, it includes at least one of the following:
[0289] 1. If the transmission time of the second SI is delayed to the first downlink time period, and the first downlink time period is not within the second SI window, the network device discards or stops sending the second SI.
[0290] Correspondingly, if the transmission time of the second SI is delayed to the first downlink time period, and the first downlink time period is not within the second SI window, the terminal device will not receive the second SI.
[0291] 2. If the transmission time of the second SI is delayed to the second downlink time period, and the second downlink time period conflicts with the third SI window, the network device shall discard or stop sending the third SI.
[0292] Correspondingly, if the transmission time of the second SI is delayed to the second downlink time period, and the second downlink time period conflicts with the third SI window, the terminal device will not receive the second SI;
[0293] 3. If the transmission time of the third SI is delayed to the third downlink time period, the third downlink time period conflicts with the third SI window, and both the second SI and the third SI occupy the first number of subframes, the network device shall send the second SI and the third SI within the third SI window.
[0294] Correspondingly, if the transmission time of the third SI is delayed to the third downlink time period, the third downlink time period conflicts with the third SI window, and both the second SI and the third SI occupy the first number of subframes, the terminal device receives the second SI and the third SI within the third SI window.
[0295] 4. If the transmission time of the second SI is delayed to the fourth downlink time period, and the fourth downlink time period is not within any SI window, the network device transmits the second SI during the fourth downlink time period.
[0296] Correspondingly, if the transmission time of the second SI is delayed to the fourth downlink time period, and the fourth downlink time period is not within any SI window, the terminal device receives the second SI during the fourth downlink time period.
[0297] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2104. For example, the combination of steps S2101 and S2102 can be implemented as an independent embodiment; the combination of steps S2101, S2102 and S2103 can be implemented as an independent embodiment; the combination of steps S2101, S2102 and S2104 can be implemented as an independent embodiment, but is not limited thereto.
[0298] In some embodiments, steps S2102 and S2103 may be performed in an alternate order or simultaneously.
[0299] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or substituted in different embodiments.
[0300] In some embodiments, step S2103 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0302] Figure 2d is a second exemplary interactive schematic diagram of an information processing method according to an embodiment of the present disclosure. As shown in Figure 2d, the information processing method includes the following steps:
[0303] Step S2201: The network device sends SI to the terminal device according to the downlink time period.
[0304] In some embodiments, the downlink time period is used to transmit downlink data based on IoT-NTN.
[0305] In some embodiments, the SI includes the SIB1-NB, and the start frame for transmitting the SIB1-NB is located in the downlink time period for transmitting downlink data based on IoT-NTN.
[0306] In some embodiments, the start frame for transmitting the SIB1-NB is the start frame for the first transmission of the SIB1-NB.
[0307] In some embodiments, the start frame is configured by the network device.
[0308] In some embodiments, the start frame is based on the MIB-NB configuration.
[0309] In some embodiments, the configuration methods for sending the start frame of SIB1-NB include, but are not limited to, the following two:
[0310] Method 1: Configure the SFN corresponding to the start frame; for example, configure the system frame number of the start frame to be 1, that is, the start frame used to send SIB1-NB is the first frame in the TDD cycle (i.e., SFN=1).
[0311] Method 2: Configure the offset value of the starting frame relative to the 0th system frame. For example, if the offset value is configured to be 2, then the starting frame is the frame with an offset value of 2 relative to the 0th frame (SFN=0) in the TDD cycle. That is, the starting frame used to send SIB1-NB is the second frame (SFN=2) in the TDD cycle.
[0312] In some embodiments, SI includes SIB1-NB, and the start frame for transmitting SIB1-NB is located in the downlink time period, which is used to transmit downlink data based on IoT-NTN.
[0313] In some embodiments, the network device may send SIB1-NB in N consecutive downlink time periods.
[0314] In some embodiments, the specific value of N is not limited in this disclosure. For example, the value of N is 8, that is, there are 8 downlink time periods for transmitting SIB1-NB, and SIB1-NB is repeatedly transmitted in these 8 downlink time periods.
[0315] In some embodiments, SI includes a first SI, which is transmitted within a first SI window.
[0316] In some embodiments, SI includes a second SI and a third SI, wherein the second SI is transmitted in a second SI window and the third SI is transmitted in a third SI window.
[0317] It should be noted that the specific methods for sending SIB1-NB, the first SI, the second SI, and the third SI are shown in the embodiment shown in Figure 2a, and will not be repeated here.
[0318] The following is an exemplary embodiment of the information processing method provided according to embodiments of this disclosure:
[0319] In some embodiments, the information processing method provided in this disclosure includes the transmission of SIB1 (SIB1-NB) and other SIBs, and the information processing method is applied to IoT-NTN TDD mode.
[0320] In some embodiments, the IoT-NTN TDD mode uses an FDD frame structure, in which a portion of the frames are used by IoT-NTN TDD. Every 90ms period, there is a downlink duration and a UL duration based on IoT-NTN TDD. The duration of the UL duration and DL duration is 8ms, and the interval between adjacent UL duration and DL duration in IoT-NTN is 50ms.
[0321] In some embodiments, each DL duration occupies two consecutive radio frames (two SFNs);
[0322] In some embodiments, the transmission method of SIB1-NB specifically includes: transmitting SIB1-NB for eight consecutive DL durations (downlink frames for IoT NTN TDD mode).
[0323] In some embodiments, the starting frame for the first transmission of the SIB1-NB is configured by the network;
[0324] In some embodiments, the initial frame of the first transmission of the SIB1-NB is configured via the MIB-NB;
[0325] In some embodiments, configuring the start frame for the first transmission of SIB1-NB includes at least one of the following methods:
[0326] Configure the frame number of the starting frame, such as SFN;
[0327] Configure the frame number of the starting frame relative to SFN=0;
[0328] In some embodiments, the UE (terminal device) determines the frame number of the start frame according to the network configuration;
[0329] In some embodiments, in the information processing method provided by this disclosure, if different SIs of the same SI window conflict, the SI is sent according to at least one of the following methods:
[0330] If a delay caused by a non-DL duration leads to a conflict with the SI of the next DL duration, the delayed SI is discarded.
[0331] If a conflict occurs between an SI and a SI in the next DL duration due to a delay caused by a non-DL duration, and if the SI only requires 2 subframes to be transmitted, then 2 SIs (2 repetitions) will be transmitted in the next DL duration.
[0332] If the SI overflows due to the SI requiring 8 subframes to be transmitted, and is delayed until the next DL duration, then the overflowed portion of the SI is discarded.
[0333] In some embodiments, in the information processing method provided by this disclosure, if a conflict occurs between different SI windows, the SI is sent according to at least one of the following methods:
[0334] If the delay to the next DL duration transmission is due to a non-DL duration, and the next DL duration is already outside the SI window, then stop / discard the SI transmission.
[0335] If the delay to the next DL duration transmission is due to a non-DL duration, and if the next DL duration transmission conflicts with another SI window transmission, then stop / discard the SI transmission.
[0336] If the delay is due to non-DL duration and transmission is delayed to the next DL duration, if the next DL duration conflicts with another SI window transmission, or if both SI windows only require 2 subframes for their SIs, then both SIs will be transmitted simultaneously in the next SI window.
[0337] If the delay to the next DL duration transmission is due to a non-DL duration, and the next DL duration is already in a non-SI window, but the next DL duration is not in another SI window, then continue with the SI transmission.
[0338] In some embodiments, the above methods may include the methods of the embodiments described above on the network device side, terminal device side, etc., which will not be repeated here.
[0339] It should be noted that, unless otherwise specified, each step in the embodiments of this disclosure can be implemented as an independent embodiment, and the steps can be arbitrarily combined. The order of the steps in any embodiment of this disclosure can be arbitrarily interchanged, and the optional implementation methods in any embodiment can be arbitrarily combined. Furthermore, different embodiments can be arbitrarily combined; for example, some or all of the steps in different embodiments can be arbitrarily combined, one embodiment can be arbitrarily combined with the optional implementation methods of other embodiments, and so on.

For example, an apparatus is provided that includes units or modules for implementing the steps performed by the network device in any of the above methods.

In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.
[0342] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
