[0001] The present application claims priority to the Chinese patent application No. 202411389815.3, filed on September 29, 2024, and entitled "Communication method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, in particular to a communication method and apparatus. BACKGROUND

[0003] With the rapid development of information technology, the demand for efficiency, maneuverability and diversity in the field of communication is increasingly urgent. In important fields such as space communication, aviation communication, marine communication and military communication, satellite communication has become an indispensable means of communication due to its unique advantages, such as wide area or even global coverage capability. Satellite communication systems not only can provide economic and reliable communication services for remote areas, but also can be integrated with the ground 5th generation mobile communication technology (5G) network to jointly build a global seamless coverage of sea, land, air and sky integrated comprehensive communication network, and meet the diversified business needs of users.

[0004] Although satellite communication has shown many significant advantages, in the process of actual deployment and integration with the 5G network, it is inevitable to encounter some technical bottlenecks. In particular, satellite communication, especially non-terrestrial network (NTN) satellites, faces the problem of significant communication channel link loss, which is particularly serious when the signal is blocked, such as when the terminal device is placed in the pocket or bag, which can cause the user to be unable to normally receive the paging message, thereby affecting the continuity and reliability of communication. SUMMARY

[0005] The present application provides a communication method and apparatus for improving the continuity and reliability of communication.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0007] In a first aspect, a communication method is provided, which is applied to a network device. The execution subject of the method can be a network device, a component or apparatus (such as a processor, a chip, or a chip system, etc.) applied to the network device, or a logic module or software capable of realizing all or part of the functions of the network device. The communication method comprises: transmitting first information for indicating a paging message based on a first configuration; and transmitting the first information based on a second configuration in the case of meeting a first condition.

[0008] In the first aspect, when the first information sent by the network device based on the first configuration cannot be received by the terminal device (this situation can be determined by the network device based on the first condition), the network device sends the first information based on the second configuration, which can improve the possibility of the terminal device receiving the first information, and further improve the continuity and reliability of the communication.

[0009] In a possible design, the method can further include: sending a downlink synchronization signal based on a third configuration; and when the first condition is met, sending the downlink synchronization signal based on a fourth configuration.

[0010] In this design, when the first information sent by the network device based on the first configuration cannot be received by the terminal device (this situation can be determined by the network device based on the first condition), the network device sends the downlink synchronization signal based on the adjusted configuration (the third configuration is adjusted to the fourth configuration), and then sends the first information based on the second configuration, so that the configuration for sending the downlink synchronization signal and the configuration for sending the first information are adjusted at the same time, which can improve the possibility of the terminal device receiving the first information, and further improve the continuity and reliability of the communication.

[0011] In a possible design, the first condition includes that the second information used for indicating the paging response message is not received within a first preset time.

[0012] In this design, based on the above-mentioned first condition, the first information can be sent based on the second configuration in time, which can improve the possibility of the terminal device receiving the first information.

[0013] In a possible design, the method can further include: receiving a third signal used for indicating adjustment of the configuration for sending the first information, and at this time, the first condition can include receiving the third signal. Optionally, the method can further include: sending third information used for indicating a sequence configuration of the third signal.

[0014] In this design, based on the above-mentioned first condition, the terminal device actively sends the third signal, and then triggers the network device to send the first information based on the second configuration in time, which can improve the possibility of the terminal device receiving the first information. Optionally, the network device indicates the third information used for indicating the sequence configuration of the third signal to the terminal device, which can ensure that the third signal can be received by the network device.

[0015] In a possible design, after sending the first information based on the second configuration, the method can further include: when the second information used for indicating the paging response message is not received within a second preset time, sending the first information based on a fifth configuration. Optionally, the method can further include: sending a downlink synchronization signal based on a sixth configuration.

[0016] In the design, when the first information sent by the network device based on the first configuration cannot be received by the terminal device, and the first information sent by the network device based on the second configuration cannot be received by the terminal device, the first information is sent based on the fifth configuration. The step-by-step adjustment of the configuration of sending the first information improves the possibility of the terminal device receiving the first information, and improves the continuity and reliability of the communication.

[0017] In a possible design, the first configuration includes a first sending power and / or a first time-frequency domain resource, and the second configuration includes a second sending power and / or a second time-frequency domain resource corresponding to the first configuration.

[0018] In the design, two optional configurations are designed, and by adjusting the two configurations, the quality of the signal carrying the first information when reaching the terminal device can be improved, and the possibility of the terminal device receiving the first information can be improved.

[0019] In a second aspect, a communication method is provided, which is applied to a terminal device. The execution subject of the method can be the terminal device, a component or device (for example, a processor, a chip, or a chip system) applied to the terminal device, or a logic module or software capable of realizing all or part of the functions of the terminal device. The communication method comprises: sending a third signal for indicating the terminal device to adjust the configuration of sending first information, in a case where a second condition is met, the first information being used for indicating a paging message; and then receiving the first information.

[0020] In the second aspect, the terminal device actively sends the third information in a case where the second condition is met, which can timely trigger the network device to send the first information based on the second configuration, and improve the possibility of the terminal device receiving the first information.

[0021] In a possible design, the method can further comprise: receiving third information, the third information being used for indicating a sequence configuration of the third signal; and when the third signal is sent, the sending can comprise: sending the third signal based on the sequence configuration of the third signal.

[0022] In the design, the network device indicates third information for indicating the sequence configuration of the third signal to the terminal device, and then the terminal device sends the third signal based on the sequence configuration of the third signal, which can ensure that the third signal is received by the network device.

[0023] In a possible design, the second condition comprises: no first message other than a downlink broadcast message is received within a third preset time.

[0024] In the design, when the terminal device cannot receive the first message other than the downlink broadcast message for a third preset time, it can be determined that the terminal device is in a weak shielding state. A third signal for indicating adjustment of a configuration for sending the first information is triggered to be sent by the terminal device to the network device, and then the network device is triggered to send the first information based on the second configuration, thereby improving the possibility of the terminal device receiving the first information.

[0025] In a possible design, the third signal is used to indicate that the network device adjusts the power and / or time-frequency domain resource for sending the first information.

[0026] In the design, two optional configurations indicated by the third signal are designed. By adjusting the two configurations, the quality of the signal carrying the first information when reaching the terminal device can be improved, thereby improving the possibility of the terminal device receiving the first information.

[0053] The network architecture and service scenario described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It can be known by those skilled in the art that, with the evolution of network architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0054] Before introducing the embodiments of the present application, some terms related to the embodiments of the present application are explained.

[0055] Downlink synchronization signal: The downlink synchronization signal refers to a series of binary signal sequences periodically transmitted by a base station at a specific location. These signal sequences are used to help terminal devices (such as mobile phones) achieve synchronization with the base station in terms of frequency, phase, 10 ms frame, and cell level. Only after successful synchronization, the terminal device can correctly demodulate the master information block (MIB) and system information block (SIB) broadcast by the cell, thereby establishing a communication connection with the base station.

[0056] When a mobile terminal (such as a mobile phone) is powered on or enters a new network environment, it first needs to search for and identify the downlink synchronization signal of the base station. By demodulating and analyzing these synchronization signals, the terminal can achieve synchronization with the base station in terms of time, frequency, and other parameters. After synchronization between the terminal and the base station is established, the base station can begin to send paging messages.

[0057] Paging message: The paging message sent by the base station to the terminal device is a broadcast message initiated by the network side to find and notify a specific mobile user (i.e., terminal device). When the network has signaling or data to send to a mobile terminal device in a non-connected state, since the network may not know the specific location of the terminal device, it will initiate a paging process to attempt to establish a connection with the terminal device through broadcast paging messages.

[0058] Paging response message: The paging response message sent by the terminal device to the base station is a message sent by the terminal device to the base station after receiving the paging message sent by the base station, in order to confirm receipt and prepare for connection establishment. This message indicates that the terminal device has received the paging and is ready for subsequent communication processes.

[0059] With the rapid development of information technology, the demand for efficient, mobile, and diverse communication is increasingly urgent. In this context, satellite communication has shown irreplaceable importance in key fields such as space, aviation, and military. Compared to terrestrial mobile communication networks, satellite communication, with the deployment of high, medium, and low orbit satellites, has achieved extensive coverage worldwide, providing non-discriminatory communication services to global users. In the future, the deep integration of satellite communication and 5G technology will complement each other's advantages and jointly build a seamless integrated communication network covering air, land, sea, and space, meeting the diverse business needs of users and becoming an important development trend in the communication field.

[0060] This integration not only reflects in the economic and reliable network services in remote areas, aircraft, and offshore vessels where ground networks are difficult to reach, but also significantly enhances the continuous network connection capabilities of Internet of Things devices and mobile carriers such as vehicles, especially through the synergy of satellites and 5G, greatly improving the service efficiency of 5G systems in these scenarios. In addition, the broadcast / multicast advantage of satellite communication also provides efficient data distribution services for network edges and user terminals.

[0061] Currently, the development of satellite mobile communication is moving towards miniaturization of mobile terminals and broadbandization of communication services, supporting a variety of handheld devices and providing rich services including high-speed data services and Internet multimedia communication, further promoting the innovation and development of communication technology.

[0062] Although satellite communication has shown many significant advantages, there are still technical bottlenecks in actual deployment and integration with 5G networks. Among them, the communication channel link loss of NTN satellite is particularly prominent, especially in the case of signal obstruction (such as terminal devices being placed in pockets or bags), which can seriously affect the reception of paging messages and reduce the continuity and reliability of communication.

[0063] Currently, the method of increasing signal repetition is mainly adopted to improve the link budget and ensure that terminal devices can receive signals when they are obstructed. However, increasing the number of signal repetitions to improve the link budget will occupy more time resources, and different obstruction conditions correspond to different required repetition numbers, and dynamically adjusting the repetition number will bring greater complexity to channel design.

[0064] To solve the above technical problems, the embodiments of the present application provide a communication method, which is described below in conjunction with the accompanying drawings of the specification.

[0065] The communication method provided by the embodiments of the present application can be applied to various communication systems, such as long term evolution (LTE) systems, 5G mobile communication systems, wireless fidelity (WiFi) systems, future communication systems, or systems that integrate multiple communication systems, etc. The embodiments of the present application do not make any limitations. Among them, 5G can also be referred to as NR.

[0066] The communication method provided by the embodiments of the present application can be applied to various communication scenarios, for example, can be applied to one or more of the following communication scenarios: enhanced mobile broadband (eMBB), ultra reliable low latency communication (URLLC), machine type communication (MTC), massive machine type communication (mMTC), device to device (D2D), vehicle to everything (V2X), vehicle to vehicle (V2V), and internet of things (IoT), etc.

[0067] In order to facilitate understanding of the embodiments of the present application, the application scenarios used by the present application are described taking the communication system architecture shown in FIG. 1 as an example. FIG. 1 shows a possible, non-limiting system schematic diagram. As shown in FIG. 1, the communication system 3000 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one network device (such as 101a and 101b in FIG. 1, collectively referred to as 101) and at least one terminal (such as 102a-102j in FIG. 1, collectively referred to as 102). The RAN 100 can also include other RAN nodes, for example, wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1), etc. The terminal 102 is connected to the network device 101 in a wireless manner. The network device 101 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the network device 101 in the RAN 100 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0068] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, e.g., a 4G, 5G mobile communication system, or an evolutional system after 5G. The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a WiFi system. The RAN 100 can also be a communication system that combines two or more of the above systems.

[0069] The apparatus provided by the embodiments of the present application can be applied to the network device 101 or the terminal 102. It can be understood that FIG. 1 only shows one possible communication system architecture to which the embodiments of the present application can be applied, and in other possible scenarios, other devices can also be included in the communication system architecture.

[0070] The network device 101 is a node in the RAN, and can also be referred to as an access network device, and can also be referred to as a RAN node (or device). The network device 101 is used to help the terminal to realize wireless access. The plurality of network devices 101 in the communication system 3000 can be nodes of the same type or nodes of different types. In some scenarios, the roles of the network device 101 and the terminal 102 are relative, for example, the network element 102i in FIG. 1 can be a helicopter or a drone, which can be configured as a mobile base station. For the terminal 102j that accesses the RAN 100 through the network element 102i, the network element 102i is a base station; but for the base station 101a, the network element 102i is a terminal. The network device 101 and the terminal 102 are sometimes collectively referred to as communication apparatuses, for example, the network elements 101a and 101b in FIG. 1 can be understood as communication apparatuses with base station functions, and the network elements 102a-102j can be understood as communication apparatuses with terminal functions.

[0071] In a possible scenario, the network device can be a base station, an evolved NodeB (eNodeB), a transmitting and receiving point (TRP), a transmitting point (TP), a next generation NodeB (gNB), a base station in a future mobile communication system, a satellite, or an access point (AP) in a WiFi system, an integrated access and backhaul (IAB) node, a network device in a non-terrestrial network (NTN) communication system, i.e., can be deployed in a high-altitude platform or a satellite, etc. The network device can be a macro base station (e.g., 101a in FIG. 1), a micro base station or an indoor station (e.g., 101b in FIG. 1), a relay node or a donor node, or a wireless controller in a cloud radio access network (CRAN) scenario. The network device can also be a device assuming a base station function in device to device (D2D) communication, vehicle-to-everything (V2X) communication, unmanned aircraft communication, or machine communication. Alternatively, the network device can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in V2X technology can be a road side unit (RSU).

[0072] In another possible scenario, a terminal accesses a wireless network by cooperation of multiple network devices, and each network device implements part of functions of a base station. For example, a network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately configured, or can be included in a same network element, for example, a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, for example, a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It can be understood that a network device can be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU can be a network device in a radio access network (RAN), or the CU can be a network device in a core network (CN), which is not limited here.

[0073] In different systems, the CU (or CU-CP and CU-UP), DU, or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an open-radio access network (O-RAN) system, the CU can also be referred to as an O-RAN central unit (O-CU) (open CU), the DU can also be referred to as an O-RAN distributed unit (O-DU), the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RAN radio unit (O-RU). For the convenience of description, the CU, CU-CP, CU-UP, DU, and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0074] In the embodiments of this application, the form of the network device is not limited, and the device for implementing the functions of the network device can be the network device; or can be a device capable of supporting the network device to implement the functions, for example, a chip system. The device can be installed in the network device or used in combination with the network device.

[0075] The terminal device 102, which can also be referred to as a user equipment (UE), a mobile station (MS), a mobile terminal (MT), or the like, or a device configured to provide voice or data connectivity to a user, can also be an Internet of Things (IoT) device. For example, the terminal device can include a handheld device having wireless connection capability, a vehicle-mounted device, or the like. Currently, the terminal device can be a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID), a wearable device (e.g., a smart watch, a smart bracelet, a pedometer, smart glasses, or the like), a vehicle-mounted device (e.g., a car, a bicycle, an electric vehicle, an airplane, a ship, a train, a high-speed rail, or the like), a satellite terminal, a virtual reality (VR) device, an augmented reality (AR) device, a smart point of sale (POS) machine, a customer-premises equipment (CPE), a light UE, a reduced capability UE (REDCAP UE), a wireless terminal in industrial control, a smart home device (e.g., a refrigerator, a television, an air conditioner, an electricity meter, or the like), a smart robot, a mechanical arm, a workshop device, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a flight device (e.g., a smart robot, a hot air balloon, a drone, an airplane), or the like. The terminal device can also be a vehicle device, such as a whole vehicle device, a vehicle-mounted module, a vehicle-mounted chip, an on board unit (OBU), or a telematics box (T-BOX), or the like. The terminal device can also be other devices having terminal functions, for example, the terminal device can also be a device performing a terminal function in D2D communication.

[0076] Embodiments of the present application do not limit the form of the terminal device, and the device for implementing the function of the terminal device can be the terminal device, or can be a device capable of supporting the terminal device to implement the function, such as a chip system. The device can be installed in the terminal device or used in combination with the terminal device. In embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices. All or part of the functions of the terminal device in the present application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform).

[0077] The foregoing has introduced the communication system to which the embodiments of the present application are applicable from the dimension of macro architecture. To help deepen the understanding of the system in the actual application environment, the communication system will be described more specifically in the following through several examples of specific communication systems. It should be noted that the following listed examples of communication systems are for illustrative purposes and are intended to provide intuitive understanding, and the actual application range of the present application is far beyond this, and other types of communication systems also have compatibility and adaptability, which are not limited.

[0078] Exemplarily, the communication system of the embodiments of the present application can be an NTN communication system, which is unique in that the mobile terminal on the ground accesses the network by means of 5G new radio (NR) technology, and the 5G base station is innovatively deployed on the satellite and seamlessly connected to the core network on the ground through a wireless link. This architecture also includes a wireless link between satellites to support signaling interaction between base stations and efficient transmission of user data.

[0079] As shown in FIG. 2, the communication system includes:

[0080] Terminal device, as can be seen from the foregoing.

[0081] Base station (satellite): as a wireless access service provider, responsible for allocating wireless resources for accessing terminals, ensuring the reliability and security of data transmission, and achieving this by implementing advanced wireless transmission protocols and data encryption mechanisms.

[0082] Core network: comprehensive control and management center, covering functions such as user access control, mobility management, session management, security authentication and charging. It is internally divided into control plane and data plane, which are composed of multiple functional units respectively, such as access and mobility management unit (access and mobility management function, AMF) responsible for user access, security verification and mobility management; user plane unit (user plane function, UPF) focuses on user data transmission and traffic statistics, etc., connected with data network; service management function (service management function, SMF) is mainly responsible for session management, quality of service (quality of service, QoS) control, access network (access network, AN) selection and charging functions.

[0083] Ground station: as a bridge between satellite base station and ground core network, responsible for forwarding signaling and service data between the two, ensuring smooth and unobstructed information flow.

[0088] In combination with the above communication system, the embodiment of the present application provides a communication method. In the communication method, when the first information sent by the network device based on the first configuration cannot be received by the terminal device (this situation can be determined by the network device based on the first condition), the network device sends the first information based on the second configuration, which can improve the possibility of the terminal device receiving the first information, and further improve the continuity and reliability of the communication.

[0089] It should be noted that in the following embodiments of the present application, the names of messages between network elements, the names of parameters, or the names of information, etc. are only examples, and in other embodiments, they can also be other names. The communication method provided by the present application does not specifically limit this.

[0090] It can be understood that in the embodiments of the present application, each network element can perform part or all of the steps in the embodiments of the present application. These steps or operations are only examples, and the embodiments of the present application can also perform other operations or variations of various operations. In addition, each step can be executed in a different order according to the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are executed.

[0091] It can be understood that the terminal device and the network device are taken as an example in the present application to illustrate the execution subject of the interaction, but the present application does not limit the execution subject of the interaction. For example, the method executed by the terminal device in the present application can also be executed by a module (such as a chip, a chip system, or a processor) applied to the terminal device, and can also be realized by a logical node, a logical module or software that can realize all or part of the functions of the terminal device; the method executed by the network device in the present application can also be executed by a module (such as a chip, a chip system, or a processor) applied to the network device, and can also be realized by a logical node, a logical module or software that can realize all or part of the functions of the network device, and the embodiments of the present application do not specifically limit this.

[0092] FIG. 3 shows a flowchart of a communication method provided by the embodiments of the present application. As shown in FIG. 3, the method can include the following steps:

[0093] S310, the network device sends first information to the terminal device based on the first configuration.

[0094] The first configuration can include at least one of the first transmission power P1 or the first time-frequency domain resource TF1.

[0095] Transmission power refers to the energy consumed by the transmitting end in the process of wireless communication. It is usually measured in milliwatts (mW) or decibels milliwatts (dBm). The size of the transmission power directly affects the transmission distance and quality of the signal. Specifically, the larger the transmission power, the stronger the signal transmission distance and penetration ability, and the wider the coverage. However, too high transmission power may also lead to increased signal interference and energy consumption, so in practical applications, the transmission power needs to be reasonably set to balance the relationship between coverage, signal quality and energy consumption. The first transmission power is the transmission power used by the network device to send the first information to the terminal device.

[0096] Time-frequency domain resource is a basic resource used for data transmission in wireless communication, corresponding to time domain and frequency domain respectively.

[0097] Time domain resource: refers to the allocation of wireless signals in time. In a wireless communication system, time is divided into a series of time slots or frames for carrying different signals and data. Effective use of time domain resources can improve the efficiency and accuracy of data transmission. For example, in 5G networks, ultra-short time slot technology is used to divide a signal period into smaller time slots, making signal transmission more accurate and fast.

[0098] Frequency domain resource: refers to the frequency range of radio waves. In wireless communication, different frequency resources are allocated to different users or services to achieve multiple access and spectrum multiplexing. Effective use of frequency domain resources can improve spectral efficiency and system capacity. For example, 5G networks use high frequency bands (such as millimeter wave bands) to provide faster data transmission, and use spectrum sharing technology to improve spectral utilization.

[0099] In the embodiments of the present application, when adjusting the time-frequency domain resource, either the time domain resource or the frequency domain resource can be adjusted alone, or both the time domain resource and the frequency domain resource can be adjusted at the same time, without limitation.

[0100] The first time-frequency domain resource is the time-frequency domain resource used by the network device to send the first information to the terminal device.

[0101] When the terminal device is in the shielding state, the terminal device can not receive the first information sent by the network device based on the first configuration. Specifically, the terminal device can be divided into a weak shielding state and a strong shielding state. In the weak shielding state, the terminal device can receive a downlink synchronization signal but cannot receive the first information indicating the paging message. For example, the terminal device is in a pocket or bag. In the strong shielding state, the terminal device cannot receive the downlink synchronization signal and cannot receive the first information indicating the paging message.

[0102] The first information is used to indicate the paging message. The manner in which the network device sends the first information to the terminal device can be flexibly designed. For example, the first information can be carried in a physical downlink shared channel (PDSCH), or the first information can be carried in a signal sequence.

[0103] In S320, the network device sends the first information to the terminal device based on the second configuration if the first condition is met.

[0104] The first condition is a condition for the network device to determine whether the terminal device is in the shielding state. If the network device determines that the terminal device is in the shielding state based on the first condition, the network device sends the first information to the terminal device using the second configuration different from the first configuration.

[0105] For example, as shown in FIG. 4, in S310, the first configuration can include P1 and / or TF1. In S320, the second configuration can be an enhanced P1 (referred to as a second transmission power P2), and / or the second configuration can also be an adjusted TF1 (referred to as a second time-frequency domain resource TF2). The terminal device can detect information on the second time-frequency domain resource to receive the first information. The second time-frequency domain resource can be specified by a protocol or agreed upon in advance by the terminal device and the network device. In other words, the second configuration can be interpreted as an enhanced first configuration.

[0106] On the one hand, the network device can significantly improve the penetration and coverage of the signal carrying the first information by enhancing the transmission power of the first information sent to the terminal device, especially in areas with severe shielding. This adjustment not only helps the terminal device in the shielding state to more stably receive the paging message, but also reduces signal attenuation to a certain extent and improves the quality of the signal when it reaches the terminal device.

[0107] On the other hand, by adjusting the time-frequency domain resource for sending the first information to the terminal device, not only the coverage of the signal carrying the first information can be significantly expanded, but also the quality of the signal can be effectively improved. Specifically, such adjustment gives the network device higher flexibility, enabling it to optimize the transmission time and frequency of the signal for a specific area (such as a severely shaded area). By increasing the transmission power of the signal or adjusting to a more suitable frequency, the penetration of the signal is enhanced, thereby ensuring that the terminal device can more stably receive the paging message even in a shaded environment. In addition, the optimization of the time-frequency domain resource can also effectively reduce the mutual interference between signals, especially in shaded areas, where signals are easily blocked and reflected by obstacles such as buildings and trees, leading to a decline in quality. By adjusting the transmission time and frequency, these interference sources can be avoided, significantly improving the quality of the signal reaching the terminal device.

[0108] In an optional embodiment, the first condition can be that the second information indicating the paging response message (referred to as paging unsuccessfully) is not received within a first preset time. The first preset time is a specific period of time that the network device expects to be able to receive a paging response message (such as a reply to confirm the receipt of the paging) from the terminal device after sending the first information indicating the paging message. Specifically, the first preset time can be flexibly set according to network planning, device performance, communication protocols, and actual application scenarios, without limitation.

[0109] For example, the first preset time can be implemented by starting a timer or a counter.

[0110] It can be understood that the terminal device may or may not receive the first information sent by the network device based on the second configuration. If it does not receive it, it can perform step S370 below, which is not described here.

[0111] Alternatively, as an alternative embodiment, the first condition can also be that the network device receives a third signal indicating the adjustment of the configuration for sending the first information to the terminal device. At this time, the method can also optionally include:

[0112] S330, the terminal device sends a third signal to the network device under the condition that the second condition is met, and correspondingly, the network device receives the third signal from the terminal device.

[0113] The second condition is a condition set by the terminal device for judging whether it is in a shaded state. For example, the second condition can be that the brightness of the ambient light is persistently low.

[0114] Alternatively, the second condition can also be that the first message other than the downlink broadcast message is not received within a third preset time. When the terminal device cannot receive the first message other than the downlink broadcast message for a third preset time, it can be determined that the terminal device is in a weak shielding state. For example, the terminal device can start from the last time when the first message other than the downlink broadcast message is received, and a specific time period in which the terminal device is expected to receive the next first message. Specifically, the third preset time can be flexibly set according to network planning, device performance, communication protocol, actual application scenario and various factors, without limitation.

[0115] At this time, the terminal device can actively send a third signal to the network device to indicate adjustment of the configuration of sending the first information to the terminal device. The sequence configuration applied by the terminal device to send the third signal can be specified by the protocol, agreed in advance by the terminal device and the network device, or indicated by the network device to the terminal device. For the way of indicating the sequence configuration of the third signal to the terminal device by the network device, the method can also optionally include:

[0116] S340, the network device sends third information to the terminal device, and correspondingly, the terminal device receives the third information from the network device.

[0117] The third information is used to indicate the sequence configuration of the third signal. After receiving the third information, the terminal device can send the third signal based on the sequence configuration of the third signal in step S330.

[0118] For example, the third information can indicate a random access occasion (RO).

[0119] In the embodiment of the application, when the first information sent by the network device based on the first configuration cannot be received by the terminal device (this situation can be determined by the network device based on the first condition), the network device sends the first information to the terminal device based on the second configuration, which can improve the possibility of receiving the first information by the terminal device, and further improve the continuity and reliability of communication.

[0120] In an embodiment, optionally, as shown in FIG. 5, the method can further include:

[0121] S350, the network device sends a downlink synchronization signal to the terminal device based on a third configuration.

[0122] The third configuration is similar to the first configuration, and the third configuration can also include at least one of the third transmission power P3 or the third time-frequency domain resource TF3. The third configuration can be the same as the first configuration, or can be different, without limitation.

[0123] S360, in the case of meeting the first condition, sending the downlink synchronization signal to the terminal device based on a fourth configuration.

[0124] The first condition can be referred to the description of step S320, and will not be repeated. As described above, the reception of the downlink synchronization signal by the terminal device is a necessary condition to ensure that the terminal device can receive the paging message. Considering that the terminal device also has the possibility of not receiving the downlink synchronization signal, before performing step S320 (the network device sends the first information to the terminal device based on the second configuration in the case of meeting the first condition), the network device can also send the downlink synchronization signal to the terminal device based on a fourth configuration different from the third configuration. For example, as shown in FIG. 6, in step S350, the third configuration can also include P3 and / or TF3. In step S360, the fourth configuration can be an enhanced P3 (referred to as a fourth transmission power P4), and / or the fourth configuration can also be an adjusted TF3 (referred to as a fourth time-frequency domain resource TF4). In other words, the fourth configuration can be interpreted as an adjusted third configuration. The adjustment range can be flexibly configured, and even for the scenario in which the terminal device can receive the downlink synchronization signal, the adjustment range can be zero, that is, the third configuration and the fourth configuration are the same, and are not limited.

[0125] It can be understood that the fourth configuration and the second configuration can be different or different. For example, taking the configuration of the transmission power as an example, the enhanced third transmission power (the fourth configuration) can be less than the enhanced first transmission power (the second configuration).

[0126] In the embodiments of the present application, when the first information sent by the network device based on the first configuration cannot be received by the terminal device (this situation can be determined by the network device based on the first condition), the network device sends the downlink synchronization signal to the terminal device based on the adjusted configuration (adjusted from the third configuration to the fourth configuration), and then sends the first information to the terminal device based on the second configuration. In this way, the configuration for sending the downlink synchronization signal to the terminal device and the configuration for sending the first information to the terminal device are adjusted at the same time, which can improve the possibility of the terminal device receiving the first information, and further improve the continuity and reliability of the communication.

[0127] In an embodiment, as shown in FIG. 7, after step S320 (the network device sends the first information to the terminal device based on the second configuration), the method further includes:

[0128] S370, in the case that the network device does not receive the second information within the second preset time, sending the first information to the terminal device based on a fifth configuration.

[0129] The second preset time is similar to the first preset time. The second preset time is a specific time period during which the network device is expected to be able to receive a paging response message (such as a reply to the paging message) from the terminal device after the network device sends the first information indicating the paging message based on the second configuration in step S320. Specifically, the second preset time can be flexibly set according to network planning, device performance, communication protocols, and actual application scenarios, and is not limited.

[0130] If the network device does not receive the second information within the second preset time, it indicates that the terminal device cannot receive the first information indicating the paging message sent by the network device based on the second configuration in step S320. At this time, the terminal device is likely to be in a strong shielding state. At this time, in order to ensure that the terminal device can receive the first information, the configuration can be further adjusted based on the second configuration, and the first information can be sent to the terminal device based on the adjusted configuration (i.e., the fifth configuration). For example, as shown in FIG. 8, the fifth configuration can be an enhanced second transmission power (referred to as a fifth transmission power P5), and / or the fifth configuration can also be an adjusted second time-frequency domain resource (referred to as a fifth time-frequency domain resource TF5). In other words, the fifth configuration can be interpreted as an enhanced second configuration.

[0131] Optionally, before step S370, the method can further include:

[0132] S380, sending a downlink synchronization signal to the terminal device based on the sixth configuration.

[0133] As described above, the reception of the downlink synchronization signal by the terminal device is a necessary condition to ensure that the terminal device can receive the paging message. Considering that the terminal device is likely to be in a strong shielding state and cannot receive the downlink synchronization signal when the network device does not receive the second information within the second preset time, the downlink synchronization signal can be sent to the terminal device based on the adjusted sixth configuration before step S370 is performed.

[0134] It can be understood that in the embodiments of the present application, step S360 (sending a downlink synchronization signal to the terminal device based on the fourth configuration when the first condition is met) is an optional step. Therefore, when step S360 is not performed, the sixth configuration can be understood as an enhanced third configuration. When step S360 is performed, the sixth configuration can be understood as an enhanced fourth configuration.

[0135] For example, as shown in FIG. 9, the sixth configuration can be the enhanced fourth transmission power (referred to as the sixth transmission power P6), and / or the sixth configuration can also be the adjusted fourth time-frequency domain resource (referred to as the sixth time-frequency domain resource TF6). In other words, the sixth configuration can be interpreted as an adjusted fourth configuration. The purpose of the adjustment is to enhance the possibility of the terminal device receiving the downlink synchronization signal, and therefore, taking the configuration of the transmission power as an example, the sixth transmission power can be greater than the fourth transmission power.

[0136] It can be understood that the sixth configuration and the fifth configuration can be different or can be different. For example, taking the configuration of the transmission power as an example, the sixth transmission power can be less than the fifth transmission power.

[0137] Optionally, if the network device has not received the second information for indicating the paging response message within a certain time after performing S370 (sending the first information to the terminal device based on the fifth configuration), the network device can discard the current paging.

[0138] In the embodiments of the present application, when the first information sent by the network device based on the first configuration cannot be received by the terminal device, and the first information sent by the network device to the terminal device based on the second configuration cannot be received by the terminal device, the first information is sent to the terminal device based on the fifth configuration. The step-by-step adjustment of the configuration for sending the first information to the terminal device makes it possible to reduce the waste of configuration resources as soon as possible, improves the possibility of the terminal device receiving the first information, and further improves the continuity and reliability of the communication.

[0139] In summary, the present application designs a step-by-step transmission configuration adjustment method for sending the first information for indicating the paging message and the downlink synchronization signal, and adjusts the transmission configuration step by step based on the set conditions (for example, the first condition), so that the possibility of the terminal device receiving the first information is improved as soon as possible under the premise of reducing the waste of configuration resources, and the continuity and reliability of the communication are further improved.
