[0091] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1, the communication system 100 may include a terminal 101 and a network device 102; wherein, the network device 102 may include at least one of an access network device and a core network device.

The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), wireless backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a wireless fidelity (WiFi) system.

[0094] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0095] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0096] In some embodiments, the core network equipment can be a single device, such as a network element, or multiple devices or a group of devices, each comprising all or part of the network element. The network element can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0097] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0098] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0099] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other information transmission methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0100] In some embodiments, the signal processing can be categorized into transparent transmission mode and regeneration mode, depending on the satellite's signal processing method. In transparent transmission mode, the NTN ground station transmits the gNB signal to the satellite. The satellite converts the signal to its own frequency band and then transmits it to the UE. Aside from frequency conversion and signal amplification, the satellite does not demodulate the gNB signal, acting similarly to a repeater. In regeneration mode, after the NTN ground station transmits the gNB signal to the satellite, the satellite first demodulates and decodes the signal before re-encoding and modulating it (this process is called regeneration) and then transmits the regenerated signal through its own frequency band.

[0101] In some embodiments, in a non-terrestrial network (NTN), a terminal needs to access the network based on satellite-aided information (or parameters). Satellite-aided information includes ephemeris data, timing advance (TA) parameters, scheduling offset k_offset, and the validity period and epoch of uplink (UL) synchronization information.

[0102] In some embodiments, satellite-aided information for the primary cell (PCell) can be provided through NTN configuration (NTN-config) in System Information Block (SIB) 19.

[0103] In some embodiments, NTN-config can provide the parameters required for a terminal to access the network via NTN. In terrestrial network (TN) cells, this field exists only in the NTN Neighbor Cell Configuration List (ntn NeighCellConfigList) and the Extended NTN Neighbor Cell Configuration List (ntn NeigholCellConfigListExt).

[0104] In some embodiments, the SIB19 may also transmit dedicated system information (SI) in Radio Resource Control (RRC) reconfiguration.

[0105] In some embodiments, for primary and secondary cells (PSCells) in carrier aggregation (CA) and / or dual connectivity (DC), the terminal needs to know satellite access-related auxiliary information, such as NTN configuration (Non-terrestrial Network Configuration, NTN-config), in order to access the PSCell. NTN-config is typically provided when a PSCell is added. If updating the NTN-config is required, it needs to be done through a PSCell reconfiguration with synchronization process; that is, the NTN-configuration of the PSCell needs to be performed through a reconfiguration with synchronization procedure.

[0106] In some embodiments, for secondary cells (SCells) in carrier aggregation (CA) and / or dual connectivity (DC) scenarios, the configuration information of the non-terrestrial network (NTN) is typically found in the secondary cell's configuration parameters, such as within the Information Element (IE) of the secondary cell common configuration (sCellConfigCommon) within the secondary cell configuration (SCellConfig). Furthermore, this NTN configuration can only be configured during the process of adding a secondary cell (SCell). This means that once an SCell is added and configured, its NTN configuration cannot be changed unless the SCell is reconfigured or deleted (released) and then re-added.

[0107] In some embodiments, NTN configurations need to be updated frequently to adapt to changes in the network environment or to meet user needs. For example, ephemeris information has an expiration date and needs to be updated after it expires. If updates are performed by releasing and adding SCells, it will cause SCell service interruption and may also lead to primary cell interruption (potentially up to 1ms). Furthermore, the network device will need to re-provide all SCell configurations to the terminal.

[0108] In some embodiments, to reduce signaling overhead, NTN parameters can be configured for each satellite, or a satellite identifier (ID) can be configured for each serving cell.

[0109] In some embodiments, satellite-aided information can be placed in a higher-dimensional information element (IE), that is, outside the configuration of the Master Cell Group (MCG) and / or Secondary Cell Group (SCG), such as directly in the Radio Resource Control (RRC) Reconfiguration IE alongside them.

[0110] Figure 2 is an interactive schematic diagram of an information transmission method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to an information transmission method for a communication system 100, the method comprising:

[0111] Step S2101: The network device sends the specified information element IE to the terminal.

[0112] In some embodiments, the specified IE includes satellite auxiliary information associated with a non-terrestrial network NTN secondary cell SCell.

[0113] In some embodiments, the terminal is a non-terrestrial network (NTN) terminal, and the network device is an NTN device.

[0114] In some embodiments, the terms "non-terrestrial network", "non-land network", "non-land communication", and "non-terrestrial communication" can be used interchangeably.

[0115] In some embodiments, the IE specified above can be modified through the SCell configuration modification process. That is, network devices can modify the satellite auxiliary information associated with the NTN SCell through the SCell configuration modification process, thereby avoiding SCell service interruptions and improving the reliability of the NTN SCell service.

[0116] In some embodiments, the specified IE can be the highest-level child IE in the SCellConfig IE. That is, the parent IE of the specified IE is the SCellConfig IE, rather than a child IE or a sub-child IE in SCellConfig.

[0117] For example, the specified IE is not placed in the sCellConfigCommon IE under SCellConfig IE, but directly in SCellConfig as the highest-level child IE. Because this specified IE is not placed in sCellConfigCommon, it is not restricted to allowing this child IE to be included only when adding SCells.

[0118] In this embodiment of the disclosure, by using the highest-level sub-IE to indicate the satellite auxiliary information associated with the NTN SCell, the terminal only needs to parse the highest-level sub-IE within the SCellConfig to obtain the satellite auxiliary information associated with the NTN SCell. This ensures reliable transmission of the satellite auxiliary information associated with the NTN SCell while reducing the difficulty and time required for the terminal to obtain the information.

[0119] In some embodiments, the specified IE can be a child IE under the sCellConfigCommon IE, and there is no restriction that it can only be carried when the SCell is added.

[0120] In some embodiments, restrictions can be set separately for the sub-IEs under the sCellConfigCommon IE. That is, some sub-IEs under the sCellConfigCommon IE are restricted to only allowing the information to be carried when the SCell is added, while others are not restricted to only allowing the information to be carried when the SCell is added. The specified IE that contains the satellite auxiliary information associated with the NTN SCell can be a sub-IE under the sCellConfigCommon IE, and this sub-IE is not restricted to only allowing the information to be carried when the SCell is added.

[0121] In this embodiment of the disclosure, by utilizing the sub-IE under sCellConfigCommon IE that is not restricted to allowing only SCell additions, the satellite auxiliary information associated with the NTN SCell is indicated. Thus, by setting separate restrictions for the sub-IE under sCellConfigCommon IE, the flexibility and reliability of configuring the satellite auxiliary information associated with the NTN SCell can be improved.

[0122] In some embodiments, the specified IE can be the IE configured for the primary cell group (MCG), or it can be the IE configured for the secondary cell group (MCG), or it can be the highest-level IE in the RRC reconfiguration message.

[0123] In some embodiments, since RRC reconfiguration messages can be used to modify network connections, they may include configurations for the MCG or SCG. In this embodiment, the MCG IE or SCG IE in the RRC reconfiguration message, or the highest-level IE in the RRC reconfiguration message, can be used to indicate satellite auxiliary information associated with the NTN SCell, thereby ensuring reliable transmission of the satellite auxiliary information associated with the NTN SCell and providing conditions for flexible configuration of the satellite auxiliary information associated with the NTN SCell.

[0124] In some embodiments, the specified IE may also be the highest-level sub-IE in the Measurement Configuration (MeasConfig) IE. In this embodiment of the disclosure, by utilizing the highest-level sub-IE in the MeasConfig IE to indicate the satellite auxiliary information associated with the NTN SCell, reliable transmission of the satellite auxiliary information associated with the NTN SCell is ensured while providing conditions for flexible configuration of the satellite auxiliary information associated with the NTN SCell.

[0125] In some embodiments, satellite auxiliary information can be satellite access parameters. That is, network devices can directly and explicitly indicate satellite access parameters to the terminal.

[0126] In some embodiments, satellite access parameters may include, for example, ephemeris data, timing advance (TA) parameters, scheduling offset k_offset, validity period of uplink (UL) synchronization information, and epoch time.

[0127] In some embodiments, satellite auxiliary information may also be a satellite identifier. That is, network devices can indirectly indicate satellite access parameters to terminals through satellite identifiers. After receiving the satellite identifier, the terminal can look up and determine the corresponding satellite access parameters based on the satellite identifier; this disclosure does not limit this.

[0128] In some embodiments, the IE specified above may include satellite auxiliary information associated with each specified satellite, wherein the specified satellite is a satellite associated with the serving cell or a satellite associated with a neighboring cell.

[0129] In some embodiments, the satellite associated with the serving cell may also be referred to as the serving satellite, which may be a satellite covering the serving cell where the terminal is currently located.

[0130] In some embodiments, the satellite associated with a neighboring cell can be a satellite of a neighboring cell that covers the serving cell where the terminal is currently located.

[0131] In some embodiments, the network device can indicate auxiliary information of the associated satellite to the terminal through each MCG or SCG.

[0132] In some embodiments, since different terminals correspond to different serving cells or neighboring cells, the network device may indicate to each terminal the auxiliary information of the satellite associated with its corresponding serving cell, and / or the auxiliary information of the satellite associated with its corresponding neighboring cell.

[0133] In some embodiments, the highest-level sub-IE in the MeasConfig IE may include the identifier of the satellite corresponding to each frequency. This allows the terminal to determine the access parameters of the satellite corresponding to each frequency, and then access the satellite corresponding to the target frequency when needed.

[0134] In some embodiments, satellite-aided information associated with neighboring cells can be indicated by measuring the highest-level sub-IE of the configured IE.

[0135] In some embodiments, the highest-level sub-IE in the MeasConfig IE may also include the identifier of the satellite associated with each neighboring cell. This allows the terminal to determine the access parameters of the satellite associated with each neighboring cell, and then access the satellite associated with that neighboring cell based on those access parameters when needed.

[0136] In some embodiments, the terminal may receive a specified information element (IE) sent by the network device, wherein the specified IE includes satellite auxiliary information associated with the non-terrestrial network NTN secondary cell (SCell).

[0137] In this embodiment of the disclosure, the network device can indicate the satellite auxiliary information associated with the NTN SCell to the terminal through a designated IE, thereby improving the flexibility and reliability of indicating the satellite auxiliary information associated with the NTN SCell and avoiding service interruptions caused by configuring the satellite auxiliary information associated with the NTN SCell by releasing and adding SCells.

[0169] For a detailed description of step S4101 and various possible embodiments, please refer to the above embodiments.

[0170] The following is an exemplary description of the above method.

[0171] In this embodiment of the disclosure, the network device provides the terminal with configuration information of the NTN SCell, which includes satellite-related auxiliary information of the SCell.

[0172] In some embodiments, satellite-related auxiliary information takes the following forms:

[0173] Format 1: Directly provide specific auxiliary information, such as satellite access-related parameters: ephemeris data, common timing advance parameters, scheduling offset k_offset, validity period and epoch time of uplink (UL) synchronization information, etc. In other words, satellite access-related parameters can be compared with the NTN-config in the 5G New Radio (NR) NTN.

[0174] Option 2: Provide satellite ID. You can find the corresponding satellite-related auxiliary information using the satellite ID.

[0175] In some embodiments, satellite-related auxiliary information for SCell is placed in a specific IE that can be modified through the SCell configuration modification process.

[0176] In some embodiments, the satellite auxiliary information can be directly placed in the SCellConfig IE as the highest-level sub-IE.

[0177] For example, the highest-level child IE means that the parent IE of this child IE is SCellConfig IE, not a child IE or a sub-child IE in SCellConfig.

[0178] In some embodiments, the satellite auxiliary information is not placed in sCellConfigCommon under SCellConfig IE, but is placed directly in SCellConfig as the highest-level sub-IE, and there are no restrictions that this sub-IE can only be carried when SCell is added.

[0179] In some embodiments, the satellite auxiliary information can be placed directly in sCellConfigCommon IE under SCellConfig IE, but sCellConfigCommon IE does not have the restriction that it can only be carried when adding SCells.

[0180] For example, for sub-IEs under sCellConfigCommon IE, you can further restrict which SCells can only carry this information when adding them. However, there is no restriction on satellite-related auxiliary information being carried only when adding SCells.

[0181] In some embodiments, the satellite ID is included in the SCell configuration information.

[0182] In some embodiments, the satellite ID is placed directly in the SCellConfig IE as the highest-level child IE, or in the sCellConfigCommon IE of the SCellConfig IE. The satellite ID can be modified through the SCell configuration modification process.

[0183] In some embodiments, the network device provides satellite auxiliary information for each designated satellite.

[0184] In some real-time scenarios, satellite auxiliary information for each specified satellite is provided through each MCG and / or SCG, for example, within the MCG and / or SCG configuration IE in the RRC reconfiguration message. Alternatively, it can be provided for each terminal (per UE), for example, by placing it directly in the RRC reconfiguration message as the highest-level IE, rather than within the MCG and / or SCG configuration IE in the RRC reconfiguration message.

[0185] In some real-time scenarios, the designated satellite can be a serving satellite (or a satellite associated with the serving cell), or a satellite associated with a neighboring cell.

[0186] In some real-time scenarios, network devices can provide satellite auxiliary information for service satellites, as well as auxiliary information for satellites associated with neighboring cells.

[0187] In some real-time scenarios, auxiliary information from satellites associated with neighboring cells can be directly used as the highest-level sub-IE of the MeasConfig IE, rather than being placed in the measurement object configuration.

[0188] In some real-time scenarios, network devices carry satellite IDs in their measurement configurations.

[0189] In some real-time scenarios, network devices provide satellite IDs per frequency in the measurement configuration, and / or per neighboring cell in the measurement configuration.

[0190] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0191] It should be understood that the division of units or modules in the above device is only a logical functional division. 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.

[0192] 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).
