[0039] The embodiments of the present disclosure propose an information processing method, apparatus, device, system, storage medium and program product for ensuring the reliability of system information SI transmission, improving network service quality and reliability, and meeting the high requirements of modern communication systems for speed, efficiency and security.
[0040] In a first aspect, an embodiment of the present disclosure provides an information processing method, which is executed by a network device. The method includes:
[0041] Send system information SI to the terminal device according to the downlink time period;
[0042] The downlink time period is used to transmit downlink data based on the Internet of Things - Non-Terrestrial Network IoT-NTN.
[0043] In the embodiments of the present disclosure, in the IoT-NTN scenario, it is possible to ensure that network devices can send SI to terminal devices within the downlink time period used to transmit downlink data based on IoT-NTN, thereby ensuring the reliability of SI transmission, enabling terminal devices to quickly obtain necessary information, and thus perform data processing and response faster, thereby improving network service quality and reliability, and meeting the high requirements of modern communication systems for speed, efficiency, and security.
[0044] In combination with some embodiments of the first aspect, in some embodiments, the SI includes a narrowband system information block 1 SIB1-NB, and a start frame for sending the SIB1-NB is located in a downlink time period.
[0045] In the disclosed embodiment, SIB1-NB contains key system information. By aligning the SIB1-NB transmission start frame with the downlink time period, it can ensure 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 in N consecutive downlink time periods.
[0048] In the disclosed embodiment, by sending SIB1-NB in multiple consecutive downlink time periods, the chance of a terminal device successfully receiving information is increased, thereby improving the success rate and efficiency of the terminal device accessing the network.
[0049] In combination with some embodiments of the first aspect, in some embodiments, the value of N is 8.
[0050] In the disclosed embodiment, by sending SIB1-NB in 8 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 combination with some embodiments of the first aspect, in some embodiments, the start frame is configured by a network device.
[0052] In the disclosed embodiments, by configuring the start frame, network devices can more effectively manage spectrum resources, avoid conflicts and interference, and ensure efficient transmission of downlink data and SI. Furthermore, by optimizing the start frame configuration, terminal devices can receive system information within the expected time window, reducing waiting time and improving reception efficiency. Furthermore, network devices can dynamically adjust the start frame based on current network conditions, load conditions, 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 combination with some embodiments of the first aspect, in some embodiments, the start frame is configured based on a narrowband master information block MIB-NB.
[0054] In the disclosed embodiments, MIB-NB typically contains key system parameters and configuration information. Configuring the start frame based on MIB-NB ensures that SIB1-NB maintains consistency with the configuration of the entire network, enhancing synchronization between the network and terminal devices. Furthermore, MIB-NB is typically updated and adjusted based on network conditions. Configuring the start frame based on MIB-NB enables SIB1-NB 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 start frame relative to the system frame 0.
[0058] In the disclosed embodiment, by configuring the offset value of the SFN or the 0th frame of the system frame, the network device can accurately control the transmission time of SIB1-NB. This accuracy helps ensure that the terminal device receives the 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, the SI includes a first SI, and the first SI is transmitted in a first SI window;
[0060] Send SI to the terminal device according to the downlink time period, including at least one of the following:
[0061] If the transmission time of the first SI is not within the downlink time period, discard the first SI;
[0062] If the transmission time of the first SI is not within the downlink time period, delaying the transmission of the first SI to the downlink time period;
[0063] If the transmission time of the first SI conflicts with the transmission time of repeated transmission of the first SI, discarding the first SI;
[0064] When a transmission time of the first SI conflicts with a repeated transmission time of the first SI and the subframes occupied by the first SI are the first number, sending the first SI;
[0065] When the transmission time of the first SI conflicts with the repeated transmission time of the first SI and the subframes occupied by the first SI are the second number, discarding the first SI;
[0066] In a case where the transmission of the first SI requires a second number of subframes, a portion of the first SI that has not been completely sent in a downlink time period is discarded.
[0067] In the disclosed embodiments, by flexibly handling SI transmission, the network can strike a balance between resource utilization, transmission efficiency, and reliability, 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 SI that is not in the downlink time period, unnecessary transmission attempts are avoided, network resources are saved, and overall transmission efficiency is improved;
[0069] When the SI transmission time does not match the downlink time period, delaying transmission instead of immediate transmission can better utilize the downlink time period window and optimize resource allocation;
[0070] When transmission time conflicts occur, discarding or adjusting transmission strategies can reduce channel interference and resource conflicts, ensuring that the transmission of other critical data is not affected. This also reduces transmission failures caused by conflicts or insufficient resources, improving network stability and service quality.
[0071] Moreover, whether to discard or transmit is determined based on the number of subframes occupied by the SI, which can flexibly adapt to different network conditions and requirements and optimize the transmission strategy.
[0072] In conjunction with some embodiments of the first aspect, in some embodiments, the SI includes a second SI and a third SI, the second SI is transmitted in a second SI window, and the third SI is transmitted in a third SI window;
[0073] Send SI to the terminal device according to the downlink time period, including at least one of the following:
[0074] When the transmission time of the second SI is delayed to the first downlink time period and the first downlink time period is not in the second SI window, discarding or stopping sending the second SI;
[0075] When 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, discarding or stopping sending the third SI;
[0076] When 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 the second SI and the third SI both occupy the first number of subframes, sending the second SI and the third SI in the third SI window;
[0077] When the transmission time of the second SI is delayed to the fourth downlink time period and the fourth downlink time period is not in any SI window, the second SI is transmitted in the fourth downlink time period.
[0078] In the disclosed embodiment, by flexibly handling the transmission time and window conflicts of the second SI and the third SI, the network device can strike a balance between resource utilization, transmission efficiency and reliability, enhance the adaptability of the system and user experience, and thus improve the overall performance of the network.
[0079] Among them, by choosing to discard, stop sending, or adjust the transmission time in different situations, network resources can be better utilized, avoiding unnecessary transmission attempts and resource waste;
[0080] When a conflict occurs in the SI window, some SI are discarded or stopped from being sent, thus reducing channel interference and resource conflicts and ensuring that the transmission of other important data is not affected.
[0081] In the event of a conflict, SI is selectively sent within the SI window to ensure effective utilization of resources and improve transmission efficiency.
[0082] If the second SI transmission time is delayed to the fourth downlink time period and the fourth downlink time period is not in any SI window, the second SI is transmitted in the fourth downlink time period. By optimizing the SI transmission strategy, users can ensure that they can receive important system information in a timely manner, improving the user experience.
[0083] In conjunction with some embodiments of the first aspect, in some embodiments, the first number is 2;
[0084] The second number is 8.
[0085] In the disclosed embodiments, by specifying the number of subframes occupied by SI, network devices can more accurately manage and allocate resources. A first number of 2 SIs occupies fewer resources and can be transmitted more flexibly within a limited time window, while a second number of 8 SIs occupies more resources and requires a larger time window. In the event of a conflict, priority is given to transmitting the SI that occupies fewer subframes (the first number is 2), which can improve transmission efficiency and ensure that more SIs can be successfully transmitted with limited resources.
[0086] In a second aspect, an embodiment of the present disclosure provides an information processing method, which is executed by a terminal device. The method includes:
[0087] Receiving system information SI sent by the network device according to the downlink time period;
[0088] The downlink time period is used to transmit downlink data based on the Internet of Things - Non-Terrestrial Network IoT-NTN.
[0089] In the embodiments of the present disclosure, in the IoT-NTN scenario, it can be ensured that the terminal device can receive the SI sent by the network device within the downlink time period used to transmit downlink data based on the IoT-NTN, thereby ensuring the reliability of SI transmission, enabling the terminal device to quickly obtain necessary information, thereby performing data processing and response more quickly, improving network service quality and reliability, and meeting the high requirements of modern communication systems for speed, efficiency, and security.
[0090] In combination with some embodiments of the second aspect, in some embodiments, the SI includes a narrowband system information block 1 SIB1-NB, and a start frame for sending the SIB1-NB is located in a downlink time period.
[0091] In some embodiments, receiving system information SI sent by a network device according to a downlink time period includes:
[0092] Receive SIB1-NB in N consecutive downlink time periods.
[0093] In combination with some embodiments of the second aspect, in some embodiments, the value of N is 8.
[0094] In combination with some embodiments of the second aspect, in some embodiments, the start frame is configured by a network device.
[0095] In combination with some embodiments of the second aspect, in some embodiments, the start frame is configured based on a 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 start frame relative to frame 0 in the system frame.
[0099] In conjunction with some embodiments of the second aspect, in some embodiments, the SI includes a first SI, and the first SI is transmitted in a first SI window;
[0100] Receiving SI sent by the network device according to the downlink time period, including 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 is not received;
[0102] If the transmission time of the first SI is not within the downlink time period, delaying the reception of the first SI to the downlink time period;
[0103] If the transmission time of the first SI conflicts with the transmission time of repeated transmission of the first SI, the first SI is not received;
[0104] receiving the first SI when a transmission time of the first SI conflicts with a repeated transmission time of the first SI and the subframes occupied by the first SI are a first number;
[0105] When the transmission time of the first SI conflicts with the repeated transmission time of the first SI and the subframes occupied by the first SI are the second number, the first SI is not received;
[0106] In a case where the transmission of the first SI requires a second number of subframes, a portion of the first SI that has not been completely sent in a downlink time period is not received.
[0107] In the embodiment of the present 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 adaptability of the system and user experience.
[0108] Among other things, by not receiving SI at inappropriate times, the terminal device can avoid unnecessary resource consumption and optimize the use of its energy and processing resources.
[0109] When the SI transmission time does not match the downlink time period, delaying reception or not receiving can improve reception efficiency and ensure that the terminal device receives information within the appropriate time window;
[0110] When a transmission time conflict occurs, 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.
[0111] Not receiving SI when it is not necessary can reduce the energy consumption of the terminal device.
[0112] In conjunction with some embodiments of the second aspect, in some embodiments, the SI includes a second SI and a third SI, the second SI is transmitted in the second SI window, and the third SI is transmitted in the third SI window;
[0113] Receiving SI sent by the network device according to the downlink time period, including at least one of the following:
[0114] When the transmission time of the second SI is delayed to the first downlink time period and the first downlink time period is not in the second SI window, the second SI is not received;
[0115] When 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 is not received;
[0116] When 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 the second SI and the third SI both occupy the first number of subframes, receiving the second SI and the third SI in the third SI window;
[0117] When the transmission time of the second SI is delayed to the fourth downlink time period and the fourth downlink time period is not in any SISI window, the second SI is received in the fourth downlink time period.
[0118] In the embodiment of the present 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 adaptability of the system and user experience.
[0119] Among them, by not receiving SI at inappropriate times, the terminal device can avoid unnecessary resource consumption and ensure that resources are used for more important or more appropriate transmissions.
[0120] When a conflict occurs in the SI window, the terminal device can reduce channel interference and resource conflicts by not receiving the conflicting SI, ensuring that the reception of other important data is not affected.
[0121] Whether to receive is determined based on the number of subframes occupied by the SI. For example, when the number of subframes occupied by the SI is small (such as the first number is 2), it can be flexibly received within a limited time window.
[0122] In the event of a conflict, SI is selectively received within a suitable time window to ensure effective utilization of resources and improve reception efficiency.
[0123] In conjunction with some embodiments of the second aspect, in some embodiments, the first number is 2;
[0124] The second number is 8.

[0166] First, some of the terms involved in the embodiments of the present disclosure are 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] Master Information Block-Narrowband (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 FIG. 1 is an exemplary schematic diagram of an NTN network architecture provided according to an embodiment of the present disclosure. Figure 1a As shown, the NTN network architecture includes terminal devices 1101, satellites 1102, and NTN gateways 1103 (or NTN ground stations). Terminal devices can use satellites (or drones) rather than ground base stations to provide wireless resources. The NTN network architecture can be divided into transparent transmission mode and regeneration mode, depending on how the satellite processes signals.
[0185] Figure 1b FIG. 1 is an exemplary schematic diagram of an NTN network architecture in a transparent transmission mode according to an embodiment of the present disclosure. Figure 1b In the NTN network architecture shown, the NG-RAN includes RRUs and network equipment 1203 (i.e., base stations (gNBs)). The RRUs may include satellites 1202 and NTN gateways (or NTN ground stations). The network equipment can access the CN based on a radio access technology standard, such as the 5G radio access technology standard NR. Terminal equipment 1201 (i.e., UE) and network equipment 1203 can communicate over a wireless interface (e.g., a UU interface). Network equipment 1203 is connected to the core network via an NG interface.
[0186] exist Figure 1bIn the NTN network architecture shown, the NTN gateway sends signals from network device 1203 (e.g., a base station (gNodeB, gNB)) to satellite 1202. Satellite 1202 converts the signals to the satellite frequency band and then transmits them to terminal device 1201. In transparent transmission mode, satellite 1202 can perform frequency conversion and signal amplification on the signals from network device 1203 without demodulating them, similar to a repeater.
[0187] Figure 1c FIG. 1 is an exemplary schematic diagram of an NTN network architecture in a regeneration mode according to an embodiment of the present disclosure. Figure 1c In the NTN network architecture shown, NG-RAN includes a satellite 1302 and an NTN gateway station (or NTN ground station), and the feeder link between the NTN gateway station and the satellite 1302 is implemented through SRI.
[0188] exist Figure 1c In the NTN network architecture shown, the NTN gateway is responsible for communicating with the satellite and forwarding the received, processed signals to the gNB. After the NTN gateway sends the signal from network device 1302 to the satellite, the satellite demodulates and decodes the signal and then re-encodes and modulates it (a process known as regeneration), generating a regenerated signal that is then transmitted over the satellite frequency band. In regeneration mode, the gNB connects to the 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 the ground station 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, within the NTN TDD cycle, time slots are allocated for IoT-NTN mode. During these time slots, the NTN network architecture is used to process IoT-NTN-based data. Beyond 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 support both 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, so that the Iridium communication system can be compatible with IoT-NTN;
[0192] In some embodiments, within a 90ms period of the Iridium communication system, only one downlink timeslot and one uplink timeslot are used for IoT NTN transmission;
[0193] In some embodiments, since the Iridium communication system is a TDD system, some time slots of the Iridium communication system are used for IoT-NTN transmission, and 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 collection 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 NTNs in TDD mode compatible with the Iridium communication system, since they use the FDD frame structure, not every radio frame is used to transmit IoT-NTN services. Therefore, when the network device sends SI to the terminal device, the SI may fall on a non-IoT-NTN time or fall into a radio frame transmitted by a non-IoT NTN, which means that downlink data cannot be transmitted at that time.
[0196] In some embodiments, the terms "radio frame" and "system frame", "frame", "SFN", "system frame number", "frame number" and the like can be used interchangeably.
[0197] In response to the above-mentioned problems, the embodiments of the present disclosure provide an information processing method, apparatus, device, system, storage medium and program product. The network device sends system information SI to the terminal device according to the 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 the embodiments of the present disclosure, in the IoT-NTN scenario, it can be ensured that the network device can send SI to the terminal device within the downlink time period used to transmit downlink data based on the 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.

[0207] The information processing method, apparatus, device, system, storage medium and program product provided by the present disclosure are described in detail below with reference to the accompanying drawings.
[0208] Figure 2a This is an exemplary interactive diagram 1 of an information processing method provided according to an embodiment of the present disclosure. Figure 2a As shown, the information processing method includes the following steps:
[0209] Step S2101: The network device determines a start frame for sending SIB1-NB.
[0210] In some embodiments, SIB1-NB is narrowband system information block 1.
[0211] In some embodiments, the start frame used to send the SIB1-NB is the first time that the network device sends the start frame of the SIB1-NB to the terminal device.
[0212] In some embodiments, the start frame for sending SIB1-NB is the start frame at which the terminal device starts to receive SIB1-NB.
[0213] In some embodiments, the start frame is used to indicate the first frame of a data stream transmitting downlink data when the network device sends downlink data to the terminal device.
[0214] In some embodiments, the name of the "start frame" is not limited. For example, the "start frame" can be interchangeable with the terms "start frame", "first frame", "initial frame", "head frame", "starting frame", etc.
[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, which is used by terminal devices to determine how to access the network; the broadcast basic system information usually includes the cell identification, 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 SI.
[0219] 3. Cell selection and reselection parameters are used by terminal devices to select a suitable cell for connection when moving or stationary.
[0220] 4. PLMN information, used by terminal devices to identify and select the appropriate network for connection.
[0221] 5. Random access process parameters, used when a terminal device first accesses or re-accesses the network. Parameters include but are not limited to cell identification, access parameters, and scheduling information.
[0222] In some embodiments, the start frame for sending the SIB1-NB is located in a downlink time period for transmitting downlink data of the IoT-NTN.
[0223] In some embodiments, TDD technology is used in the NTN to support communication of IoT devices.
[0224] In some embodiments, the current NTN system / Iridium system uses the 1616-1626.5MHz spectrum. Figure 2b , Figure 2b FIG. 1 is a schematic diagram of the spectrum of NTN provided according to an embodiment of the present disclosure. Figure 2b As shown, in a 90 millisecond (ms) cycle of the Iridium system, a downlink time period and an uplink time period are allocated specifically for the IoT-NTN mode. During the uplink time period and the downlink time period, IoT NTN (such as NB-IoT NTN technology) is used to send or receive data.
[0225] In some embodiments, the term "downlink time period" is not limited. "Time period" can be interchanged with "time slot," "time," "period," "transmission time," "time interval," "duration," "duration," "time window," "window," and "duration." "Downlink" can be interchanged with "downlink," "downlink transmission," "downlink channel," "receive link," "gNB to UE direction," "DL," and "Downlink."
[0226] In some embodiments, the term "uplink time period" is not limited. "Time period" can be interchanged with "time slot," "time," "period," "transmission time," "time interval," "duration," "duration," "time window," "window," and "duration." "Uplink" can be interchanged with "uplink," "uplink transmission," "uplink channel," "transmit link," "UE to gNB direction," "UL," and "Uplink."
[0227] In some embodiments, in addition to the uplink and downlink time periods reserved for IoT-NTN mode, the other uplink and downlink time periods in the Iridium system cycle continue to support the original Iridium communications. 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 an Iridium communication period, such as 90 ms.
[0230] In some embodiments, the number of downlink time periods and uplink time periods in the same cycle may be the same. For example, each cycle 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 cycle may be different. For example, a cycle 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 the IoT NTN system in TDD mode, the FDD frame structure of the IoT NTN is still used.
[0233] In some embodiments, the IoT NTN in TDD mode uses the FDD frame structure of the 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 the IoT NTN in TDD mode uses the FDD frame structure of the IoT NTN, not every system frame is used for downlink transmission of the IoT-NTN in TDD mode. 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 the IoT NT in TDD mode, two consecutive system frames are used to transmit IoT-NTN-based downlink data.
[0235] In some embodiments, each uplink time period is of a first duration;
[0236] In some embodiments, each downlink time period is of 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 embodiment of the present disclosure does not limit the size of the first duration and the second duration. The length of the uplink duration and the downlink duration can be the same or different. Optionally, taking the uplink duration and the downlink duration as an example, the first duration can be 8 milliseconds; the second duration can be 8 milliseconds. That is, the time allocated to downlink transmission and uplink transmission in one cycle is 8 milliseconds each, wherein the uplink and downlink use the same frequency channel for simultaneous transmission.
[0239] In some embodiments, the present disclosure does not limit the size of the third duration. For example, the third duration may be 50 milliseconds.
[0240] In some embodiments, taking the FDD frame structure of IoT NTN as an example, each downlink time period of IoT NTN TDD mode uses two consecutive system frames, and 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). Among them, subframes 3, 4, 5, 6, 7, 8, 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 , Figure 2c FIG. 1 is a schematic diagram of a TDD frame structure provided according to an embodiment of the present disclosure. Figure 2c As shown, the downlink time periods in the figure include: DL#1, DL#2...DL#113, DL#114, DL#115...
[0241] 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 of SFN=0, and subframe 0 of 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, 9 in SFN=11, and subframe 0 in SFN=12).
[0246] It should be noted that the allocation method of the uplink time period for transmitting uplink data based on IoT-NTN is similar to that of the downlink time period, and will not be described here in detail.
[0247] In some embodiments, assuming that each cycle includes one downlink time period and one uplink time period, the interval between two downlink time periods is the length of the cycle. For example, assuming that the length of the cycle is 90 ms, the interval between two consecutive downlink time periods is 90 ms. For example, the interval between DL#2 and DL#1 is 90 ms; the interval between DL#14 and DL#13 is 90 ms; and the interval between DL#115 and DL#114 is 90 ms.
[0248] In some embodiments, the starting frame for sending SIB1-NB can be any frame in the downlink time period. For example, the starting frame for sending 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 SIB1-NB for the terminal device through MIB-NB, so that the terminal device can accurately receive SI based on the start frame of SIB1-NB.
[0251] In some embodiments, the start frame for sending SIB1-NB is configured based on MIB-NB. Optionally, MIB-NB includes scheduling information, wherein the scheduling information is used to indicate the start frame of 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 embodiment of the present disclosure does not limit the i-th frame. For example, the i-th frame can be any frame such as the 0th frame (SFN=0), the 1st frame (SFN=0), etc.
[0252] In some embodiments, the starting frame for sending SIB1-NB is a frame in 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] Mode 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 first start frame for sending SIB1-NB (ie, SFN=1).
[0255] Method 2: Configure the offset value of the start frame relative to the i-th frame of the system frame. It should be understood that the embodiment of the present disclosure does not limit the i-th frame. For example, the i-th frame can be any frame such as the 0th frame (SFN=0) or the 1st frame (SFN=0). For example, taking the i-th frame as the 0th frame (SFN=0) as an example, if the configured offset value is 2, the start frame is the frame with an offset value of 2 relative to the 0th frame (SFN=0), that is, the start frame for sending SIB1-NB is the second frame (SFN=2) in the cycle.
[0256] 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 sending SIB1-NB is in a downlink time period, and the downlink time period 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 respectively.
[0259] In some embodiments, the embodiments of the present disclosure do not limit the specific value of N. N can be any value greater than or equal to 1. For example, the value of N can be 8, that is, there are 8 downlink time periods for transmitting SIB1-NB, and SIB1-NB is sent in 8 consecutive downlink time periods; or the value of N can be 16, that is, there are 16 downlink time periods for transmitting SIB1-NB, and SIB1-NB is sent in 16 consecutive downlink time periods.
[0260] In the disclosed embodiments, 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 the disclosed embodiment, by sending SIB1-NB in 8 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 ,like Figure 2c As shown, the downlink time period includes DL#1 to DL#115..., wherein the N consecutive downlink time periods can be any consecutive 8 downlink time periods, for example, DL#1 to DL#8.
[0263] Step S2103: The network device sends a first SI to the terminal device.
[0264] In some embodiments, the network device uses the scheduling information provided in SIB1-NB to transmit SI within periodic time windows (referred to as SI windows). Each SI message is associated with an SI window, and SI windows for different SI messages do not overlap. In other words, only corresponding SI messages are 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, wherein the first SI is transmitted in a first SI window;
[0266] In some embodiments, since the SI window may contain non-DL time slots, this may cause the transmission of the system message to be delayed. These delays may cause the transmission of the system message to conflict with the next repetition of the system message, or overlap with other system information windows, thereby reducing the efficiency of message transmission or causing transmission failure. In an embodiment of the present 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] Correspondingly, when the transmission time of the first SI is not within the downlink time period, the terminal device does not receive the first SI. Specifically, when the transmission time of the first SI is not within the downlink time period for transmitting downlink data based on IoT-NTN, the network device does not send the first SI. Please refer to Figure 2c ,like Figure 2c As shown, if the transmission time of the first SI is at SFN=2, since SFN=2 is not a downlink time period for transmitting downlink data based on IoT-NTN, the network device discards 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 to the downlink time period.
[0270] Accordingly, if the transmission time of the first SI is not within the downlink time period, the terminal device delays receiving the first SI until the downlink time period.
[0271] Specifically, when the transmission time of the first SI is not in the downlink time period for transmitting downlink data based on IoT-NTN, the first SI is sent in the downlink time period. Figure 2c ,like Figure 2c As shown in FIG, if the transmission time of the first SI is at SFN=2, since SFN=2 is not the downlink time period for transmitting downlink data based on IoT-NTN, the first SI is delayed to the closest downlink time period for transmission. For example, the first SI can be sent to the terminal device at DL#2 (i.e., SFN=9 and SFN=10). Accordingly, the terminal device receives the first SI at DL#2 (i.e., SFN=9 and SFN=10).
[0272] 3. When the transmission time of the first SI conflicts with the transmission time of repeated transmission of the first SI, the network device discards the first SI.
[0273] Accordingly, when the transmission time of the first SI conflicts with the transmission time of the repeated transmission of the first SI, the terminal device does not receive the first SI.
[0274] In some embodiments, a conflict between the transmission time of the first SI and the transmission time of repeated transmissions of the first SI means that, in the first SI window, the transmission time of the first SI and the transmission time of repeated transmissions of the first SI overlap or interfere with each other, resulting in the terminal device possibly being unable to correctly receive all required information. In this case, the network device may not send the first SI.
[0275] 4. When the transmission time of the first SI conflicts with the repeated transmission time of the first SI, and the subframes occupied by the first SI are the first number, the network device sends the first SI.
[0276] It should be noted that within the SI window, the corresponding SI message can be repeatedly transmitted multiple times in 2 or 8 consecutive NB-IoT downlink subframes according to the transport block size (TBS). The terminal device can obtain detailed time domain / frequency domain scheduling information and other information based on the schedulingInfoList field in SIB1-NB, such as the transmission format used for the SI message. Therefore, the terminal device does not need to accumulate multiple SI messages in parallel, but may need to accumulate an SI message in multiple SI windows based on the coverage conditions.
[0277] In the first SI window, when the transmission time of the first SI overlaps or interferes with the transmission time of repeated transmission of the first SI, if the first SI occupies a first number of subframes, the first SI is sent in the first SI window.
[0278] Correspondingly, when the transmission time of the first SI conflicts with the repeated transmission time of the first SI, and the subframes occupied by the first SI are the first number, the terminal device receives the first SI in the first SI window.
[0279] It should be understood that the embodiment of the present disclosure does not limit the size of the first number. Optionally, the first number can be 2. That is, in the first SI window, if the transmission time of the first SI overlaps or interferes with the transmission time of the repeated transmission of the first SI, if the first SI occupies 2 subframes, the first SI is sent in the first SI window.
[0280] 5. When the transmission time of the first SI conflicts with the repeated transmission time of the first SI, and the subframes occupied by the first SI are the second number, the network device discards the first SI.
[0281] Correspondingly, when the transmission time of the first SI conflicts with the repeated transmission time of the first SI and the subframes occupied by the first SI are the second number, the terminal device does not receive the first SI.
[0282] It should be understood that the embodiment of the present disclosure does not limit the size of the first number. Optionally, the second number may be 8. That is, in the first SI window, if the transmission time of the first SI overlaps or interferes with the transmission time of repeated transmissions of the first SI, and if the first SI occupies 8 subframes, the network device does not send the first SI.
[0283] 6. When the transmission of the first SI requires a second number of subframes, the network device discards the portion of the first SI that has not been completely sent in a downlink time period.
[0284] Correspondingly, when the transmission of the first SI requires a second number of subframes, the terminal device does not receive the part of the first SI that has not been sent in a downlink time period.
[0285] In some embodiments, the second number may be 8. SI occupying the second number of subframes cannot be completely transmitted in one downlink time period. Therefore, if the first SI occupies 8 subframes, the network device may discard the portion of the first SI that is not completely transmitted in the downlink time period and only transmit the portion of the first SI that can be transmitted in one downlink time period.
[0286] Step S2104: The network device sends the second SI and the third SI to the terminal device.
[0287] In some embodiments, the 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.
[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. When the transmission time of the second SI is delayed to the first downlink time period and the first downlink time period is not in the second SI window, the network device discards or stops sending the second SI.
[0290] Correspondingly, when the transmission time of the second SI is delayed to the first downlink time period and the first downlink time period is not in the second SI window, the terminal device does not receive the second SI.
[0291] 2. When 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 discards or stops sending the third SI.
[0292] Accordingly, when 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 does not receive the second SI;
[0293] 3. When 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 the second SI and the third SI both occupy the first number of subframes, the network device sends the second SI and the third SI in the third SI window.
[0294] Correspondingly, when 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 in the third SI window.
[0295] 4. When the transmission time of the second SI is delayed to the fourth downlink time period and the fourth downlink time period is not in any SI window, the network device transmits the second SI in the fourth downlink time period.
[0296] Correspondingly, when the transmission time of the second SI is delayed to the fourth downlink time period and the fourth downlink time period is not in any SISI window, the terminal device receives the second SI in the fourth downlink time period.
[0297] The communication method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2104. For example, the combination of step S2101 and step S2102 may be implemented as an independent embodiment; the combination of step S2101, step S2102, and step S2103 may be implemented as an independent embodiment; and the combination of step S2101, step S2102, and step S2104 may be implemented as an independent embodiment, but are not limited thereto.
[0298] In some embodiments, step S2102 and step S2103 may be executed in an interchanged order or simultaneously.
[0299] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0311] Method 2: Configure the offset value of the start frame relative to the system frame 0. For example, if the offset value is configured to 2, the start frame is the frame with an offset value of 2 relative to the 0th frame (SFN=0) in the TDD cycle, that is, the start frame for sending 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 sending SIB1-NB is in a downlink time period, and the downlink time period 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 respectively.
[0314] In some embodiments, the embodiments of the present disclosure do not limit the specific value of N. 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 sent in these 8 downlink time periods.
[0315] In some embodiments, the SI includes a first SI, and the first SI is transmitted in a first SI window.
[0316] In some embodiments, the SI includes a second SI and a third SI, 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 for the specific methods of sending SIB1-NB, the first SI, the second SI and the third SI, please refer to Figure 2a The embodiments shown are not described in detail here.
[0318] The following is an exemplary embodiment of an information processing method provided according to an embodiment of the present disclosure:
[0319] In some embodiments, the information processing method provided by the embodiments of the present disclosure includes the transmission of SIB1 (SIB1-NB) and other SIBs, and the information processing method is applied to the IoT-NTN TDD mode.
[0320] In some embodiments, the IoT-NTN TDD mode uses the FDD frame structure, with some frames reserved for IoT-NTN TDD. Each 90ms period includes a downlink duration and an UL duration based on IoT-NTN TDD. The UL duration and DL duration are both 8ms long, and adjacent UL durations and DL durations in IoT-NTN are separated by 50ms.
[0321] In some embodiments, each DLduration occupies two consecutive radio frames (two SFNs);
[0322] In some embodiments, the SIB1-NB transmission method specifically includes: transmitting the SIB1-NB in 8 consecutive DL durations (downlink frames for IoT NTN TDD mode).
[0323] In some embodiments, the starting frame of the first transmission of SIB1-NB is configured by the network;

[0329] In some embodiments, in the information processing method provided by the embodiments of the present disclosure, for the same SI window, if different SI repetitions of the SI window conflict, the SI is sent according to at least one of the following methods:
[0330] If the SI transmission is delayed to the next DL duration due to non-DL duration, resulting in a conflict with the SI of the next DL duration, the delayed SI is discarded;
[0331] If the delay in transmitting SI to the next DL duration due to non-DL duration causes a conflict with the SI of the next DL duration, if SI only requires 2 subframes to be transmitted, 2 SIs (2 repetitions) are transmitted in the next DL duration;
[0332] If the SI overflows because it requires 8 subframes to transmit, it is delayed until the next DL duration, and the overflowed SI is discarded;
[0333] In some embodiments, in the information processing method provided by the embodiments of the present disclosure, for different SI windows, if a conflict occurs between different SI windows, SI is sent according to at least one of the following methods:
[0334] If the transmission is delayed to the next DL duration due to non-DL duration, if the next DL duration is already in the non-SI window, then SI transmission is stopped / discarded;
[0335] If the delay to the next DL duration transmission is due to non-DL duration, if the next DL duration collides with another SIwindow transmission, then SI transmission is stopped / discarded;
[0336] If the transmission is delayed to the next DL duration due to non-DL duration, if the next DL duration conflicts with another SI window transmission, and if the SIs of both SI windows only require 2 subframes, then the two SIs are transmitted simultaneously in the next SI window;
[0337] If the transmission to the next DL duration is delayed due to non-DL duration, if the next DL duration is already in the non-SIwindow, but the next DL duration is also not in other SIwindows, then SI transmission continues.
