[0201] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0202] The embodiments of the present disclosure 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (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 utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0203] In the communication system, non-terrestrial network (NTN) is an important technology in 5G. NTN can provide wireless resources through satellites (or drones) instead of ground base stations. Figure 2A is a schematic diagram of the framework of a global navigation satellite system (GNSS) measurement system provided by an embodiment of the present disclosure. As shown in Figure 2A, the GNSS measurement system includes a terminal device, which can also be called user equipment (UE) or terminal, beam projection, service link, satellite, unmanned aircraft system (UAS) platform, feeder link, gateway, data network and satellite field of view. According to the different ways in which the satellite processes signals, it can be divided into transparent transmission mode and regeneration mode.

[0204] In one embodiment of the present disclosure, Figure 2B is a schematic diagram illustrating an example of a transparent transmission mode provided by an embodiment of the present disclosure. As shown in Figure 2B, the NTN ground station transmits the signal from the next generation NodeB (gNB) to the satellite. The satellite converts the signal to the satellite frequency band and then transmits it to the UE via the satellite frequency band. Besides frequency conversion and signal amplification, the satellite does not demodulate the gNB signal. The satellite can be similar to a repeater. A 5G base station, called a gNB, provides the UE with a terminal node for the New Radio (NR) user and control plane protocols and is connected to the 5G core network (5GC) via the NG interface.

[0205] In one embodiment of the present disclosure, Figure 2C illustrates an example of a retransmission mode. As shown in Figure 2C, after the NTN ground station sends the gNB signal to the satellite, the satellite first demodulates and decodes the signal, then re-encodes and modulates it (a process known as regeneration), and transmits the regenerated signal via the satellite frequency band.

[0206] In some embodiments, for outgoing calls or messages, the user can consciously select a suitable location to initiate communication. However, taking NTN paging as an example, the paging can be a second paging notification, and the user may encounter poor reception conditions, thereby missing calls and messages, which is particularly detrimental to public safety or emergency paging messages. This poor reception condition occurs when the terminal is placed in a pocket, backpack, vehicle, vessel, etc., or in the presence of clutter loss. In Long Term Evolution (LTE), the second paging notification can be used to: trigger RRC setup; system information modification; PWS / ETWS notification. Among them, in the New Radio (NR), the function of the second paging notification is mainly used to trigger RRC setup (RRC request and RRC connection recovery). System information modification and Public Warning System (PWS) / ETWS notification are completed by P_RNTI scrambled DCIformat1_0 and associated PDSCH.

[0207] The second paging notification may include a pagingRecordList field, a PagingUE-Identity field and / or a PagingRecordList field. Alternatively, the second paging notification may be DCI format 1_0.

[0208] In some embodiments, shadow fading and clutter loss in suburban and rural scenarios - Non Light of Sight (NLOS) caused by clutter loss can exceed 18 dB. In some embodiments, Line of Sight (NLOS) probabilities show that at an altitude of 30 degrees, approximately 10% of rural users and 50% of urban users will experience NLOS.

[0209] The following describes in detail a notification sending method, apparatus, device, and storage medium provided by embodiments of the present disclosure with reference to the accompanying drawings.

[0210] FIG3A is an interactive diagram of a notification sending method provided by an embodiment of the present disclosure. As shown in FIG3A , the method may include the following steps:

[0211] Step S3101: The network device sends configuration information of a first paging notification to the terminal;

[0212] In one embodiment of the present disclosure, before sending a paging notification to a terminal, the network device may, for example, send configuration information to the terminal. The configuration information may be transmitted, for example, via RRC or DCI. This embodiment of the present disclosure is not limited to this. For related content, please refer to the text description below and will not be repeated here. This configuration information may not be a field already in PCCH-config, such as defaultPagingCycle. This embodiment of the present disclosure is not limited to this.

[0213] Step S3102: The network device sends a first paging notification to the terminal;

[0214] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0215] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0216] In one embodiment of the present disclosure, the name of the first paging notification is not limited. For example, the first paging notification may be a paging robust notification, a paging extension message, a notification message, a paging message, etc.

[0217] In some embodiments, the first paging notification may, for example, refer to a message used to indicate terminal movement. After the network device determines that the current link quality is lower than a threshold, the network device may send a paging enhancement notification message to the terminal. After the terminal receives the first paging notification, it may move. During the movement of the terminal, the network device and / or the terminal may determine the link quality. After the UE moves to a position where the link quality is higher than the threshold, it may correctly receive the normal paging message. The UE may determine the current link quality and notify the network device of the current link quality so that the network device may determine the current link quality. The link quality may be measured in a variety of ways, such as signal-to-noise ratio (SNR), RSRP, etc.

[0218] In the case where the network device is a satellite in an NTN, for example, the terminal's movement can refer to the relative movement between the terminal and the network device, i.e., it can be either terminal movement or network device movement. Because some satellites are asynchronous, after a certain period of waiting, even when the terminal is relatively stationary, the relative position of the network device and the terminal may change. Specifically, in one embodiment of the present disclosure, a paging message can, for example, be used to instruct a terminal to wait for a first period of time before listening for or receiving a paging message.

[0219] In some embodiments, when a network device determines that a paging request to any terminal fails, the network device may send a first paging notification to the terminal. For example, the network device may determine whether a paging request to any terminal fails based on link quality. When the network device determines that the terminal receives the first paging notification, the network device may send a paging message to the terminal.

[0220] In some embodiments, when the network device determines that paging of any terminal fails, it may send a first paging notification to the terminal. When the network device determines that the terminal receives the first paging notification and the first paging notification includes a paging message, the network device may not send a paging message to the terminal.

[0221] In some embodiments, the network device predicts that a paging failure has occurred at any terminal and may send a first paging notification to the terminal. The network device may, for example, predict whether a paging failure has occurred at any terminal based on link quality. Upon determining that the terminal has received the first paging notification, the network device may send a paging message to the terminal.

[0222] In some embodiments, the network device predicts that paging of any terminal fails and may send a first paging notification to the terminal. When the network device determines that the terminal receives the first paging notification and the first paging notification includes a paging message, the network device may not send a paging message to the terminal.

[0223] For example, in one embodiment of the present disclosure, the network device may send the first paging notification to the terminal in at least one of the following ways: radio resource control RRC message; downlink control information DCI; resource block.

[0224] In one embodiment of the present disclosure, the resource block may be, for example, a resource block used to send the first paging notification.

[0237] Furthermore, in one embodiment of the present disclosure, the resource block includes a synchronization signal resource for sending the first paging notification. The synchronization signal resource may specifically be, for example, a resource for sending the notification content of the first paging notification. The synchronization signal corresponding to the synchronization signal resource may, for example, carry cell identification information.

[0238] Furthermore, in one embodiment of the present disclosure, the system frame in which the synchronization signal is located may be used to indicate which system frames the synchronization signal is located in. The resource block may carry a PBCH, or may not carry a PBCH.

The Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied by the synchronization signal resource in a resource block may, for example, be used to indicate which OFDM symbols the synchronization signal resource occupies within the resource block. This embodiment of the present disclosure is not limited to this.

[0242] Furthermore, in one embodiment of the present disclosure, the time offset may be, for example, agreed upon by the system. For example, the time offset of the resource used to send the first paging notification relative to the primary synchronization signal PSS or the secondary synchronization signal SSS may be agreed upon by the system. The time offset may, for example, include the time offset of the resource used to send the first paging notification relative to the OFDM symbol, the time offset may, for example, include the time offset of the resource used to send the first paging notification relative to the subframe, and the time offset may, for example, include the time offset of the resource used to send the first paging notification relative to the slot. The embodiments of the present disclosure are not limited to this.

[0243] Furthermore, in one embodiment of the present disclosure, the number of OFDM symbols occupied by the resources used to send the first paging notification, as well as the relative frequency domain starting position and bandwidth within the resource block, may be agreed upon by the system. The number of OFDM symbols occupied by the resources used to send the first paging notification, as well as the relative frequency domain starting position and bandwidth within the resource block, may be configured by the system, for example. This embodiment of the present disclosure is not limited to this.

[0244] Furthermore, in one embodiment of the present disclosure, the MCS corresponding to the resource used to send the first paging notification may be agreed upon by the system, for example, but this embodiment of the present disclosure does not limit this.

[0245] In one embodiment of the present disclosure, the network device may transmit the resource block on one or more beams, wherein the number of beams is less than or equal to the number of system synchronization blocks SSB in a half-frame of the cell.

[0246] Furthermore, in one embodiment of the present disclosure, the period of the resource block is the same as the SSB period.

[0247] Furthermore, in one embodiment of the present disclosure, the period of the resource block is an integer multiple of the SSB period.

[0248] For example, in one embodiment of the present disclosure, the resource block includes a synchronization signal, wherein the synchronization signal is used to instruct the terminal to detect the synchronization signal of the first paging notification using a blind detection method, and determine the resource location for sending the first paging notification after detecting the synchronization signal.

[0257] In one embodiment of the present disclosure, the first indication information may be used to indicate at least one of the Earthquake and Tsunami Early Warning System (ETWS) and the Commercial Mobile Alert Service (CMAS). The first in the first indication information is only used to distinguish it from the other indication information and does not specifically refer to a fixed indication information. For example, when the specific information indicated by the first indication information changes, the first indication information may also change accordingly.

[0258] For example, in one embodiment of the present disclosure, at least one of the DCI and the new physical channel used to send the first paging notification is scrambled using a dedicated radio network temporary identifier RNTI.

[0259] For example, in one embodiment of the present disclosure, the DCI includes at least one of the following: a DCI for carrying the first paging notification; and a DCI for scheduling the first paging notification.

[0260] For example, in one embodiment of the present disclosure, the DCI for carrying the first paging notification may be executed before step S3101. This embodiment of the present disclosure does not limit this.

[0271] For example, in one embodiment of the present disclosure, resource configuration is used to configure the time domain length occupied by a resource block. The unit of the time domain length may be, for example, at least one of a symbol, a slot, and a subframe. This embodiment of the present disclosure is not limited to this.

[0296] FIG6A is a flow chart of a notification sending method according to an embodiment of the present disclosure. As shown in FIG6A , the present disclosure embodiment relates to a notification sending method, which includes:

[0297] In step S6101, the network determines to send a paging robust notification message, and sends it via a radio resource control (RRC) message or downlink control information (DCI) or a new resource block.
