Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology
[0002] Currently, for base stations with large terrestrial coverage areas, beamforming, multi-beam coverage, and massive MIMO (multiple input multiple output) technologies are typically used to enhance signal gain, concentrate energy, and reduce path loss. These techniques, combined with low-frequency transmission and high-power transmission, ensure signal quality and coverage for users at long distances. Compared to terrestrial cellular networks, non-terrestrial networks (NTNs) offer faster mobility, wider coverage, but also greater path loss.
[0003] During the initial access phase, network devices (e.g., satellite-based network devices) broadcast different synchronization signal blocks (SSBs) and system information blocks (SIBs) in all beam directions. Terminal devices within the coverage area of a particular broadcast beam under the network device complete random access based on the received SSBs and SIBs, establishing a basic signaling connection with the network device. Subsequently, the terminal device determines its own monitoring time based on its user identifier and periodically wakes up to check for its own paging message within its monitoring time. Each monitoring time generally includes one or more time slots. Since the network device does not know which broadcast beam the terminal device is within, each time it needs to paging, the network device needs to send the same paging content in all broadcast beam directions through the corresponding beam. One time slot corresponds to one paging in one broadcast beam direction. Correspondingly, the terminal device also needs to monitor for an entire monitoring time until it detects its own paging message before stopping monitoring, resulting in significant radio resource overhead. Summary of the Invention
[0004] This application proposes a communication method and apparatus that can improve the redundancy of monitoring during paging, ensure monitoring performance, reduce monitoring overhead and efficiency, and thus enhance the user experience.
[0005] In a first aspect, embodiments of this application provide a communication method applicable to a network device. This method can be executed by the network device, by components within the network device (e.g., processors, chips, circuits, or chip systems), or by a logic module or software capable of implementing all or part of the network device's functions. The method includes: sending a first message to a first region, the first message including paging resource configuration information of the first region and paging resource configuration information of N regions adjacent to the first region, where N is greater than or equal to 1; and sending paging messages to the first region and the N adjacent regions.
[0006] In the above method, the network device sends the paging resource configuration information of the first area and the paging resource configuration information of N adjacent areas to the first area. This enables the terminal device to determine a limited number of PMOs (PMOs corresponding to the first area and the N adjacent areas) based on the paging resource configuration information of the first area and the paging resource configuration information of the N adjacent areas, and to perform monitoring. This improves monitoring redundancy and ensures monitoring performance. At the same time, compared with the terminal device monitoring PO, the terminal device consumes less monitoring overhead to monitor multiple PMOs, reducing power consumption and improving monitoring efficiency.
[0007] In one possible implementation, the range of each region in the first region and the adjacent N regions are respectively the signal coverage range corresponding to different System Message Blocks (SIBs).
[0008] In the above method, the signal coverage area corresponding to one SIB is taken as a small area (i.e., a sub-area). This is beneficial for subsequent network devices to carry the first message in the SIB and send it to the small area (i.e., the sub-area), thereby achieving more targeted and refined paging scheduling, reducing interference, and improving paging success rate and paging efficiency.
[0009] In another possible implementation, the first region is a sub-region of the second region, the range of which is the signal coverage area corresponding to the synchronization information block SSB or the main information block MIB.
[0010] In another possible implementation, the first message is carried in the SIB or MIB corresponding to the first region.
[0011] In the above method, carrying the first message in the SIB corresponding to the first area is beneficial to achieve more targeted and refined paging scheduling, reduce interference, and improve paging success rate and paging efficiency; carrying the first message in the MIB corresponding to the first area enables the terminal device to obtain paging resource configuration information earlier, reducing the signaling interaction process for obtaining paging resource configuration information.
[0012] In another possible implementation, the adjacency includes adjacency in the signal coverage area or adjacency in the time domain.
[0013] In another possible implementation, the paging resource configuration information includes at least one of the following: the SIB identifier corresponding to the region, or the paging identifier corresponding to the region.
[0014] In the above method, the aforementioned approach enables subsequent terminal devices to determine the PMO corresponding to a region based on the SIB-ID and / or paging-ID in the region's paging resource configuration information, thereby identifying M candidate PMOs. This, in turn, facilitates the subsequent terminal devices in successfully monitoring one or more of the M PMOs corresponding to the M regions, improving monitoring redundancy and ensuring monitoring performance.
[0015] In another possible implementation, sending paging messages to the first region and the N adjacent regions includes:
[0016] Paging messages are transmitted through the beams corresponding to the first region and the N adjacent regions.
[0017] In the above method, paging messages are sent through a beam with a smaller coverage area corresponding to the region, which reduces the coverage area, improves the transmission performance of data signals, and ensures monitoring performance.
[0018] In another possible implementation, the first message further includes first location information, which includes the location information of the N adjacent regions, or the first location information includes the location information of the first region and the N adjacent regions.
[0019] In the above method, the aforementioned approach facilitates the subsequent determination of the preferred PMO from M candidate PMOs for monitoring by the terminal device based on its own location information and the first location information. This ensures monitoring redundancy while further reducing the monitoring overhead of the terminal device, reducing power consumption, and improving monitoring efficiency.

[0023] Secondly, embodiments of this application provide a communication method applicable to a terminal device.

[0024] In the above method, by receiving the paging resource configuration information of the first region and the paging resource configuration information of N adjacent regions sent by the network device to the first region, the terminal device can determine a limited number of PMOs (PMOs corresponding to the first region and the N adjacent regions) based on the paging resource configuration information of the first region and the paging resource configuration information of the N adjacent regions, and perform monitoring, thereby improving monitoring redundancy and ensuring monitoring performance. At the same time, compared with the terminal device monitoring PO, the terminal device consumes less monitoring overhead when monitoring multiple PMOs, reducing power consumption and improving monitoring efficiency.
[0025] In one possible implementation, the range of each region in the first region and the adjacent N regions are respectively the signal coverage range corresponding to different System Message Blocks (SIBs).
[0026] In the above method, the signal coverage area corresponding to one SIB is taken as a small area (i.e., a sub-area). This is beneficial for subsequent network devices to carry the first message in the SIB and send it to the small area (i.e., the sub-area), thereby achieving more targeted and refined paging scheduling, reducing interference, and improving paging success rate and paging efficiency.

This facilitates the subsequent terminal device to successfully monitor one or more of the M PMOs corresponding to the M regions, improves monitoring redundancy, and ensures monitoring performance.
[0033] In another possible implementation, the first message further includes first location information, which includes the location information of the N adjacent regions, or the first location information includes the location information of the first region and the N adjacent regions.
[0034] In the above method, the aforementioned approach facilitates the subsequent determination of the preferred PMO from M candidate PMOs for monitoring by the terminal device based on its own location information and the first location information. This ensures monitoring redundancy while further reducing the monitoring overhead of the terminal device, reducing power consumption, and improving monitoring efficiency.

[0039] In the above method, the terminal device can determine the preferred PMO from M PMOs based on its own location information and the first location information, which ensures monitoring redundancy while further reducing the monitoring overhead of the terminal device, reducing power consumption, improving monitoring efficiency, and thus enhancing the user experience.
[0040] In another possible implementation, the first region is a sub-region within the second region of S wide regions.

Here, S is an integer greater than or equal to 1, and H is an integer greater than or equal to 2.
[0041] The PMO corresponding to the h-th sub-region in the K-th wide region of the S wide regions is the (h-1)×S+K-th PMO or the (K-1)×H+(h-1)-th PMO, where K is an integer greater than or equal to 1 and not greater than S, and h is an integer greater than or equal to 1 and not greater than H.
[0042] In the above method, the determination relationship of PMO is defined, which enables the terminal device to determine the PMO corresponding to the region, thereby enabling the terminal device to accurately receive paging messages and ensure monitoring performance.
[0043] Thirdly, embodiments of this application provide a communication method applicable to network devices.

[0044] In the above method, the network device sends paging resource configuration information and location information of each sub-region in at least two regions to the second region. This enables the terminal device to determine multiple candidate PMOs (PMOs corresponding to each sub-region) based on the paging resource configuration information of each sub-region, thereby improving monitoring redundancy and ensuring monitoring performance. Furthermore, the terminal device can subsequently determine one or more sub-regions from the sub-regions included in the at least two regions based on its own location information and the location information of each sub-region in the at least two regions. The PMOs corresponding to these one or more sub-regions are the preferred PMOs among the multiple candidate PMOs. This allows the terminal device to monitor only the PMOs corresponding to these one or more sub-regions.

[0170] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0171] References to "one embodiment" or "some embodiments" as described in this application mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.
[0172] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, or c can represent: a, b, c; a and b; a and c; b and c; or a and b and c. Where a, b, and c can be single or multiple.
[0173] It is understood that in this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When describing a certain instruction information to indicate A, it can be understood that the instruction information carries A, directly indicates A, or indirectly indicates A.
[0174] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to instruct the information to be instructed, such as, but not limited to, directly instructing the information to be instructed, such as the information to be instructed itself or its index; indirectly instructing the information to be instructed by instructing other information, where there is a relationship between the other information and the information to be instructed; or instructing only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent.
[0175] The information to be instructed can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device.
[0176] It is understood that "send" and "receive" in this application refer to the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which can include direct transmission via the air interface or indirect transmission via the air interface from other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which can include direct reception from YY via the air interface or indirect reception from YY via the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.
[0177] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.
[0178] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.
[0179] The communication method provided in this application can be applied to cellular communication systems related to the 3rd Generation Partnership Project (3GPP), such as 4th generation (4G) communication systems, such as Long Term Evolution (LTE) communication systems, and also to 5th generation (5G) communication systems, such as 5G New Radio (NR) communication systems, or to various future communication systems and future communication networks. The method provided in this application can also be applied to Bluetooth systems, Wireless Fidelity (WiFi) systems, LoRa systems, or vehicle-to-everything (V2X) systems, communication systems supporting the integration of multiple wireless technologies, and device-to-device (D2D) systems. The method provided in this application can also be applied to satellite communication systems, wherein the satellite communication system can be integrated with the above-mentioned communication systems. The wireless communication systems involved in this application also include, but are not limited to: narrowband internet of things (NB-IoT) systems, global system for mobile communications (GSM), enhanced data rate for GSM evolution (EDGE), wideband code division multiple access (WCDMA) systems, code division multiple access 2000 (CDMA2000) systems, or time division-synchronization code division multiple access (TD-SCDMA) systems.
[0180] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application, to Figure 1The application scenario used in this application is illustrated using the communication system architecture shown. The communication system includes network equipment and terminal equipment. The network equipment is a device with wireless transceiver capabilities and can be any of the network devices described below. Optionally, the network equipment can be deployed on the ground (e.g., on land, on a ship), or on a satellite. The terminal equipment is a device with wireless transceiver capabilities and can be any of the terminal devices described below. Optionally, the terminal equipment can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (e.g., on a ship); or it can be deployed in the air (e.g., on an airplane, on a balloon). Optionally, the terminal equipment can be fixed or mobile.
[0181] For example, the terminal device can communicate with network devices of different technologies. For instance, when the network device is a base station, the terminal device can communicate with a base station that supports LTE networks, or with a base station that supports 5G networks, and can also support dual connections with both LTE and 5G base stations.
[0182] For example, network devices can communicate directly with terminal devices or through relay stations.
[0183] Optionally, the communication system may further include a core network with three main functions: registration, connection, and session management. This core network includes at least one of the following: a Network Exposure Function (NEF) network element, a Policy Control Function (PCF) network element, a Session Management Function (SMF) network element, or a User Plane Function (UPF) network element. Specifically, the NEF network element can provide 3GPP network function services and capabilities to the Application Function (AF) network element, and also allow the AF network element to provide information to the 3GPP network function; the PCF network element can manage charging policies and Quality of Service (QoS) policies; the UPF network element can perform user plane data forwarding and generate call detail records (CDRs) based on traffic conditions, while also acting as a data plane anchor point; the SMF network element can perform session management functions such as Internet Protocol (IP) address allocation for terminal devices, UPF network element selection, and charging and QoS policy control.
[0184] It should be noted that, Figure 1Taking only one network device and one terminal device as an example, in reality, the communication system can include more network devices and terminal devices, and this application embodiment does not limit this. When the communication system includes multiple network devices, these multiple network devices can be of the same type or different types.
[0185] For example, the method provided in this application embodiment can be applied to non-terrestrial network (NTN) communication systems, such as satellite communication systems. Such satellite communication systems generally include terminal equipment, satellites, and ground-based network equipment (e.g., NTN gateways and ground-based base stations, where the ground-based base stations can be referred to as terrestrial base stations). Based on their operating modes, satellite operating modes can generally be divided into two main categories: transparent mode and regenerative mode.
[0186] Please see Figure 2 , Figure 2 This is a schematic diagram of another communication system architecture provided in this application embodiment. The communication system includes an NTN architecture comprising a transparent-mode satellite, wherein the NTN architecture includes terminal equipment, a transparent-mode satellite, ground-deployed network equipment (NTN gateway and ground base station), a core network, and a data network. In transparent-mode, the satellite only acts as a frequency conversion relay, equivalent to an analog radio frequency repeater. Specifically, the satellite replicates the NR-Uu interface signal from the feed link (between the satellite and the network equipment (e.g., the NTN gateway)) to the service link (between the satellite and the terminal equipment), and vice versa. The satellite radio interface on the feed link transmits the NR-Uu interface signal; that is, the satellite does not terminate the NR-Uu interface signal but replicates it. Different transmission satellites can connect to the same ground base station. Optionally, the NTN gateway and base station in the network equipment can be integrated together (e.g., Figure 2 ), or they can be separated.
[0187] For example, Figure 2 In (1), both the terminal device to the satellite and the satellite to the NTN gateway use non-3GPP radio protocols for non-3GPP access (e.g., via wireless fidelity (WIFI)). In this case, the satellite forwards non-3GPP signals. The NTN gateway supports all necessary functions for forwarding NR-Uu interface signals. Optionally, Figure 2 The terminal equipment in (1) can be user equipment (UE), or a terminal equipment using a parabolic antenna, or a terminal equipment using a phased array antenna.
[0188] For example, Figure 2 In (2), both the terminal device and the satellite use NR Radio Protocols for 3GPP NR access (e.g., access via a cellular network, such as 5G), and the satellite relays NR signals. Optionally, Figure 2 The terminal device in (2) can be a handheld device, an Internet of Things (IoT) terminal device, a terminal device using a parabolic antenna, or a terminal device using a phased array antenna.
[0189] Please see Figure 3 , Figure 3 This is a schematic diagram of another communication system architecture provided in this application embodiment. The communication system includes an NTN architecture comprising a regenerable mode satellite. This NTN architecture includes terminal equipment, the regenerable mode satellite, ground-deployed network equipment (NTN gateway and ground base station), a core network, and a data network. In regenerable mode, the satellite has some or all of the functions of network equipment (e.g., a base station). For example, the satellite includes next-generation NodeB (gNB) equipment or distributed unit (DU), meaning that in regenerable mode, the satellite acts as a network device. In this architecture, the satellite, acting as a network device (e.g., a base station), regenerates signals received from the ground. Specifically, NR-Uu radio interface signals are transmitted on the service link between the terminal equipment and the satellite, and satellite radio interface signals are transmitted on the feeder link between the network equipment (e.g., the NTN gateway) and the satellite. The NG interface between the satellite and the gateway is carried on the satellite radio interface (SRI). The NG interface signal is transmitted to the NTN gateway via the SRI interface, and then forwarded by the NTN gateway to the ground-based core network equipment.
[0190] The apparatus provided in this application can be applied to network devices or to terminal devices. It is understood that... Figure 1 or Figure 2 or Figure 3 This application only illustrates one possible communication system architecture that can be applied to an embodiment of the present application. In other possible scenarios, the communication system architecture may also include other devices.
[0191] (1) A terminal device, also known as a user equipment (UE), mobile station (MS), or mobile terminal (MT), is a device that provides voice or data connectivity to a user. Specifically, it includes devices that provide voice connectivity to a user, devices that provide data connectivity to a user, or devices that provide both voice and data connectivity to a user. For example, it may include a handheld device with wireless connectivity or a processing device connected to a wireless modem. This terminal device can communicate with the core network via a radio access network (RAN), exchanging voice or data with the RAN, or interacting with the RAN to exchange voice and data. Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices (such as smartwatches, smart bracelets, pedometers, etc.), in-vehicle devices (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed trains, etc.), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, smart home devices (such as refrigerators, televisions, air conditioners, electricity meters, etc.), intelligent robots, workshop equipment, wireless terminals in self-driving vehicles, wireless terminals in remote surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, or wireless terminals in smart homes, and flying equipment (such as intelligent robots, hot air balloons, drones, airplanes), etc. Terminal devices can also be other devices with terminal functions; for example, a terminal device can also be a device that performs terminal functions in D2D communication.Terminal devices can also include vehicle-to-everything (V2X) terminal devices, machine-to-machine / machine-type communications (M2M / MTC) terminal devices, Internet of Things (IoT) terminal devices, light UEs, reduced capability UEs (REDCAP UEs), subscriber units, subscriber stations, mobile stations, remote stations, access points (APs), remote terminals, access terminals, user terminals, user agents, or user devices, and drone equipment. For example, they can include mobile phones (or "cellular" phones), computers with mobile terminal devices, portable, pocket-sized, handheld, and computer-embedded mobile devices. Examples include personal communication service (PCS) telephones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, and personal digital assistants (PDAs). It also includes limited devices, such as those with low power consumption, limited storage capacity, or limited computing power. Examples include information sensing devices such as barcode scanners, radio frequency identification (RFID), sensors, global positioning systems (GPS), and laser scanners. In this application, terminal devices with wireless transceiver capabilities and chips that can be installed in the aforementioned terminal devices are collectively referred to as terminal devices.
[0192] It should be noted that the terminal device may be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, module or control unit in the device or apparatus shown above. This application does not limit the specific device.
[0193] (2) A network device is a device deployed in a radio access network to provide wireless communication functions for terminal devices. A network device may also be referred to as an access network (RAN) entity, access node, network node, or communication device, etc. For example, this network device includes radio access network entities in terrestrial cellular networks and radio access network entities in NTNs.
[0194] Specifically, the network equipment can be access network equipment for cellular systems related to the 3rd Generation Partnership Project (3GPP). For example, fourth-generation (4G) mobile communication systems or 5G mobile communication systems. The network equipment can also be access network equipment in open RAN (O-RAN or ORAN) or cloud radio access network (CRAN). Alternatively, the network equipment can also be access network equipment in a communication system formed by the integration of two or more of the above communication systems.
[0195] Network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home-evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP) in Wi-Fi systems, macro base station, micro base station, wireless relay node, donor node, radio controller in CRAN scenarios, wireless backhaul node, transmission point (TP), or transmission and receiving point (TRP). Network equipment can also be access network equipment in 5G mobile communication systems. For example, next-generation base station (gNB), TRP, TP in new radio (NR) systems, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system. Alternatively, network equipment can also be network nodes constituting a gNB or transmission point. Examples include centralized units (CUs), distributed units (DUs), CU-control planes (CPs), CU-user planes (UPs), and radio units (RUs). CUs and DUs can be separate entities or included within the same network element, such as a BBU. RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). Alternatively, network equipment can be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in V2X technology, network equipment can be roadside units (RSUs).
[0196] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open centralized unit (O-CU) or an open CU, DU can also be called an open distributed unit (O-DU), centralized unit control plane (CU-CP) can also be called an open centralized unit control plane (O-CU-CP) or an open CU-CP, centralized unit user plane (CU-UP) can also be called an open centralized unit user plane (O-CU-UP) or an open CU-UP, and RU can also be called an open radio unit (O-RU). This application does not impose any specific limitations. Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.
[0197] In some deployments, the CU and DU implement some of the functions of the gNB. For example, the CU implements the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers, while the DU implements the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this architecture, higher-layer signaling, such as RRC or PDCP layer signaling, can also be considered as being sent by the DU, or by the DU+RU. It is understood that network devices can be CU nodes, DU nodes, or devices including both CU and DU nodes. Furthermore, the CU can be classified as a network device in the access network (RAN) or a network device in the core network (CN); no restrictions are placed here.
[0198] It should be noted that the network device can be the device or apparatus shown above, or a component (e.g., a chip), module, or unit in the device or apparatus shown above; this application does not limit the specifics.
[0199] The following is combined Figure 1 The communication system shown herein will be described in detail with reference to the communication method provided in the embodiments of this application.
[0200] To better understand the solutions provided in the embodiments of this application, some terms, concepts or processes involved in the embodiments of this application will be introduced below.
[0201] (1) Beam: A beam is the main lobe of a directional array pattern. For example, in new radio access technology (NR) protocols, a beam can be represented as a spatial domain filter, or a spatial filter, or a spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, or quasi-colocation (QCL) information, QCL assumption, QCL indication, etc. A beam can be indicated by a transmission configuration indication state (TCI-state) parameter or by a spatial relation parameter. Therefore, in this application, a beam can be replaced by a spatial domain filter, spatial filter, spatial parameter, spatial parameter, spatial domain setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (uplink TCI-state, downlink TCI-state), spatial relation, etc. These terms are also equivalent to each other. The term "beam" can be replaced with other beam terms, and this application embodiment does not limit it.
[0202] The beam used for transmitting signals can be called the transmission beam (Tx beam), spatial domain transmission filter, spatial transmission filter, spatial domain transmission parameter, spatial transmission parameter, or spatial domain transmission setting. The downlink transmission beam can be indicated by TCI-state. The beam used for receiving signals can be called the reception beam (Rx beam), spatial domain reception filter, spatial reception filter, spatial domain reception parameter, spatial reception parameter, or spatial domain reception setting. The uplink transmit beam can be indicated by a spatial relation, or uplink TCI-state, or channel sounding reference signal (SRS) resource (representing the transmit beam using that SRS). Therefore, the uplink beam can also be replaced by SRS resources. Optionally, the transmit beam can refer to the signal strength distribution in different spatial directions after the signal is transmitted through the antenna, and the receive beam can refer to the signal strength distribution in different spatial directions of the wireless signal received from the antenna.
[0203] Optionally, the beam can be a wide beam, a narrow beam, or other types of beam. The beamforming technology can be beamforming technology or other technologies. Specifically, beamforming technology can be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology, etc.
[0204] For example, beams generally correspond to resources. During beam measurement, network devices measure different beams using different resources, and the terminal provides feedback on the measured resource quality, allowing the network device to determine the quality of the corresponding beam. During data transmission, beam information is also indicated through its corresponding resources. For instance, network devices use the TCI field in DCI to indicate the terminal's PDSCH beam information.
[0205] Optionally, multiple beams with the same or similar communication characteristics can be considered as a single beam. A beam may include one or more antenna ports for transmitting data channels, control channels, and detection signals, etc. One or more antenna ports forming a beam can also be considered as a set of antenna ports.
[0206] In the embodiments of this application, unless otherwise specified, a beam refers to the transmit beam of a network device. In beam measurement, each beam of a network device corresponds to a resource, and therefore the beam corresponding to that resource can be uniquely identified by the resource index.
[0207] (2) Coverage Range: Coverage range can be used to indicate the projection range of the beam on the ground or the range that the signal can reach. For example, network devices can adjust the weights of their antennas so that the beams transmitted by the network devices can point in different directions and have different coverage ranges. For example, the coverage range will change as the satellite moves and the weights are adjusted. The beam coverage range discussed in the embodiments of this application refers to the coverage range of the beam on the ground.
[0208] Traditional terrestrial cellular networks (such as 5G NR) have limited coverage in remote areas, oceans (such as ocean-going vessels), and polar regions, making it difficult to meet the demand for seamless global communication. Furthermore, the accessibility and stability of terrestrial cellular networks remain challenging in scenarios such as emergency disaster relief (e.g., disaster monitoring, emergency communications), the Internet of Things, and high-speed mobility (e.g., high-speed rail, airplanes). Therefore, 6th generation (6G) communication systems and future communication systems consider scenarios requiring extremely wide coverage, improving network coverage capabilities and building a seamless global communication system.
[0209] Extremely wide coverage scenarios include the following characteristics: (1) Extremely wide coverage scenarios involve long transmission distances, large path losses, and limited power on both the network device side (e.g., base station side) and the terminal device side (e.g., UE side); (2) The network devices are located at a high position, and the channel between the network devices and users approaches line-of-sight (LOS) wireless transmission; (3) Under extremely wide coverage, it is necessary to both meet the access needs of users within the full coverage area and ensure user performance. Based on different scenario requirements, extremely wide coverage scenarios include various forms. Please refer to Figure 4 , Figure 4This is a schematic diagram of an ultra-wide coverage scenario provided in an embodiment of this application. This ultra-wide coverage scenario is a satellite scenario, in which the network equipment is located on a satellite platform. The large satellite coverage area results in a large coverage area for the network equipment on the satellite platform. Please refer to... Figure 5 , Figure 5 This is a schematic diagram of another ultra-wide coverage scenario provided in the embodiments of this application. In this scenario, the network device is located on the ground, but because the network device is located at a high altitude, it can also achieve ultra-wide coverage of tens of kilometers on the ground.
[0210] Among them, networks that use network equipment (e.g., radio frequency resources) on satellite platforms (e.g., low Earth orbit (LEO), medium Earth orbit (MEO), geostationary Earth orbit (GEO), unmanned aerial vehicle (UAV) platforms, or high-altitude platform stations (HAPS)) to provide communication services can be called non-terrestrial communication networks (NTNs). Figure 2 The scenario is illustrated. Compared to terrestrial cellular networks (such as 5G NR), NTN (Network Telecommunications) offers wider coverage, higher path loss, greater latency, faster speed, and lower cost. As a supplement and extension of terrestrial cellular networks, NTN can achieve wide-area seamless coverage that wired telephone networks and terrestrial mobile communication networks cannot, effectively solving internet access problems in areas lacking communication infrastructure. For example, by deploying a large number of satellites in Low Earth Orbit (LEO), seamless ground coverage can be achieved through reasonable constellation construction, and the round-trip transmission latency between satellites and ground terminals can be significantly reduced compared to geostationary orbit (GEO) satellites, reaching the tens of millisecond level. With the use of technologies such as high-frequency bands, multi-beamforming, and frequency reuse, satellite communication capabilities have been significantly improved, while reducing the unit broadband cost, thus meeting the needs of high-data-rate services. Compared to terrestrial 5G NR networks and submarine fiber optic cables, NTN also has a significant cost advantage. Modern small satellites have low R&D and manufacturing costs, and software-defined technologies can further extend the lifespan of satellites in orbit.
[0211] With the increasing research interest in NTN, the 3rd Generation Partnership Project (3GPP) standards organization has also conducted standardization research on NTN, aiming to achieve NTN construction using the NR architecture. 3GPP began its satellite-ground integration research with Release 14 (R14), discussing the role and advantages of satellites in 5G systems in TS22.261, and for the first time specifying 5G support for satellite access. In R15, the first 5G and satellite integration technology report (TR 38.811) was produced, defining eight enhanced mobile broadband (eMBB) scenarios and two massive machine-type communication (mMTC) scenarios, and defining the NTN channel model. R16 further studied the architecture and solutions for NR supporting NTN in TR 38.821. Based on the research results of R16, the standardization work for 5G NR supporting NTN was initiated in R17, resulting in the first version of the integration technology specification. R18 and R19 also continued corresponding NTN enhancement research. Because satellites are not easily affected by natural disasters or external damage, research is currently underway to use them as access network equipment for mobile communication systems (such as deploying base stations on satellites) to provide communication services to areas such as oceans and forests.
[0212] Taking network equipment as a base station as an example, unlike terrestrial base stations (base stations deployed on the ground, referred to as terrestrial base stations for ease of description), satellite base stations (base stations deployed on satellites, referred to as satellite base stations for ease of description) move at a greater speed and travel a longer signal propagation distance than terrestrial base stations. This results in greater signal path loss for satellite base stations. In other words, compared to terrestrial cellular networks, NTNs move faster, cover a wider area, and suffer greater transmission path loss. Therefore, the communication mechanisms currently designed for terminal devices and terrestrial base stations in mobile communication systems cannot be directly applied to communication between terminal devices and satellite base stations.
[0213] Currently, for base stations with large terrestrial coverage areas, beamforming, multi-beam coverage, and massive MIMO (Multiple-Input Multiple-Output) technologies are typically used to enhance signal gain, concentrate energy, and reduce path loss. These technologies, combined with low-frequency transmission and high-power transmission, ensure signal quality and coverage for users at long distances. Generally, terrestrial communication systems rely on several broadcast beams in different directions to send synchronization signal blocks (SSBs) to users, completing terminal synchronization during the initial access phase. Terrestrial communication systems are defined to cover the service area of a single base station with a maximum of 8 SSBs (FR1) or 64 SSBs (FR2).
[0214] To overcome signal path loss between terminal devices and satellite base stations, improve coverage, and ensure the data reception and demodulation performance of terminal devices in the network, enabling satellite base stations to provide communication services to terminal devices, unlike terrestrial communication systems where a maximum of 8 or 64 SSBs corresponding to the broadcast beams of a single base station can cover the service area, the NTN system may require hundreds or even thousands of broadcast beams. Taking an NTN system with an orbital altitude of 600km as an example, the service area of a single satellite can reach hundreds of thousands of square kilometers. To overcome the path loss caused by transmission distance and ensure communication service quality, satellites generally use large-scale antenna arrays to provide higher array gain, but this also results in a narrower beam main lobe. For example, a coverage radius of only a few tens of kilometers with a 3dB beamwidth covers an area of about several hundred square kilometers; therefore, using narrow beams to achieve seamless coverage of a single satellite's service area requires thousands of beams. Furthermore, even with some beam widening, hundreds of beams are still needed to maintain the gain level to achieve coverage. Due to the large coverage area of satellite communication, a large number of scanning beams are required. The number of beams may be 64, 128, 256, 512, etc.
[0215] The initial access phase described above generally refers to the process of a terminal device (such as a UE) connecting to the network for the first time. Its purpose is to establish a communication connection with the network, and it typically occurs when the terminal device (such as a UE) powers on or moves from one network to another. During the initial access phase, the satellite, acting as a network device, needs to scan all beams sequentially and configure random access resources for the terminal device. The initial access process includes a random access process, which generally refers to the process from when the terminal device sends a random access preamble to attempt to access the network device until a basic signaling connection is established between the terminal device and the network device. The random access preamble can be simply referred to as the preamble.
[0216] During initial access, network devices can broadcast different synchronization signals and physical broadcast channel blocks (SS / PBCH blocks) for different communication areas. These SS / PBCH blocks, also known as SSBs, are distinguished by their index numbers. Generally, different SSB indices represent downlink synchronization signals with different beam directions, covering and serving different areas. After receiving an SSB, the terminal device completes timed synchronization and confirms the time-frequency position of system information blocks (SIBs) 1 according to the information in the SSB. It then parses SIB1 to obtain cell information and detects SIB19 based on the search space configured in SIB1, completing data parsing to obtain satellite ephemeris information (for terrestrial systems, ephemeris information is not required; for satellite systems, it is required). After obtaining cell information and / or ephemeris information (required only for satellite systems), the terminal device sends a random access preamble on the corresponding uplink resources according to the configuration information and the SSB index. For network devices, the area where the terminal device is located can be determined by the received random access preamble and the corresponding uplink resources, and a connection can be established with the terminal device.
[0217] Based on its own needs, the terminal device can choose whether to establish a radio resource control (RRC) connection with the network device for communication. When the terminal device does not need to establish an RRC connection temporarily, or when the RRC connection is temporarily disconnected after being established due to lack of communication needs, the terminal device is in idle mode. At this time, when the terminal device (such as UE) in idle mode receives an incoming call, SMS, or other event that requires a response, the network device can find and notify the terminal device (such as UE) through paging.
[0218] The paging message content is sent to the terminal device (e.g., UE) via the physical downlink shared channel (PDSCH) resource location. The PDSCH resource is indicated by scrambling the physical downlink control channel (PDCCH) with a paging record new temporary identity (P-RNTI). In other words, for the terminal device (e.g., UE) to receive the paging message, it must first periodically wake up to monitor the P-RNTI-scrambled PDCCH channel, then parse the downlink control information (DCI) to obtain the time-frequency location of the PDSCH channel, and finally, the terminal device (e.g., UE) parses the paging content at the corresponding PDSCH channel location. For one example, please refer to [link to example]. Figure 6 , Figure 6 It is a DCI format for scheduling paging, in which paging supports terabyte (TB) scaling.
[0219] Regarding the acquisition of paging messages by terminal devices, in the time domain, terminal devices will only attempt to receive paging messages at a specific paging occasion (PO) within a specific frame (paging frame, PF) of their own associated paging period. Therefore, network devices need to send paging messages over the air interface at that moment so that terminal devices may receive paging messages at that moment.
[0220] In this context, a PF (Power over Frame) is a radio frame that may contain one or more POs (Points of Interest). A PO is a set of Physical Downlink Control Channel (PDCCH) monitoring occasions (PMOs), which may contain multiple slots (subframes or orthogonal frequency division multiplexing (OFDM) symbols). On this PO, there may be a PDCCH scrambled with P-RNTI and indicating a paging message. When the terminal device uses discontinuous reception (DRX), it only needs to detect one PO per DRX cycle. That is, for each terminal device, only one PO is available for sending paging messages in each paging cycle. The DRX cycle and the paging cycle are the same concept, defined in the protocol as a DRX cycle, and because it describes paging, it is also called the paging cycle.
[0221] The relevant parameters for paging are shown in Table 1 below. Among them, the 5G service temporary mobile subscriber identity (5G-S-TMSI) in the 5G network is a temporary identifier used to identify the user equipment (UE). It is usually used when exchanging information between the user equipment and the network and has the function of protecting privacy. Taking the modulo operation of 5G-S-TMSI modulo 1024 is an operation for allocating identifiers and randomizing them to prevent identifier conflicts.
[0222] Table 1
[0223]
[0224] The terminal device determines the PF and PO that need to be detected (or monitored) based on the above paging-related parameters. Among them, the PF is a system frame that satisfies Formula 1, as shown below.
[0225] (SFN+PF offset)mod T= (T div N) *(UE_ID mod N) (Formula 1)
[0226] Where SPF is the system frame number, mod is the modulo operation, and div is the division operation. T div N is equivalent to dividing a DRX cycle into N equal parts, and the number of system frames in each part. UE_ID mod N is equivalent to taking the "UE_ID mod N" part (with a value range of 0 to N-1) of the N equal parts, and PF is the first system frame in that part. In one example, if T = 8, N = 4, and PF offset = 0, then the DRX period includes eight radio frames, with system frame numbers ranging from 0 to 7. Radio frames with system frame numbers 0, 2, 4, and 6 are PFs. There are UE_ID = 0 and UE_ID = 3. For UE_ID = 0, based on (SFN + PF offset) mod T = (T div N) * (UE_ID mod N) = 2 * 0 = 0, the system frame number of the PF that the terminal device with UE_ID = 0 needs to detect is 0 + 0 = 0. Similarly, for UE_ID = 3, based on (SFN + PF offset) mod T = (T div N) * (UE_ID mod N) = 2 * 3 = 6, the system frame number of the PF that the terminal device with UE_ID = 3 needs to detect is 0 + 6 = 6. This process can be understood as assigning the terminal device to different PFs based on its UE_ID and using Formula 1 to determine the system frame number of the PF assigned to the terminal device.
[0227] Furthermore, a PF may include one or more POs. Specifically, the terminal device detects which PO in the PF is indicated by index i_s. Index i_s refers to the index of a paging opportunity (PO) within a PF, and index i_s satisfies Formula 2, as shown below.
[0228] i_s=floor(UE_ID / N)mod Ns (Formula 2)
[0229] In practice, each PO corresponds to s consecutive PDCCH detection opportunities, where s refers to the number of SSBs actually broadcast in an SSB burst, that is, the number of beams used by the network device to send SSBs in an SSB burst. Since the network device does not know which beam range the terminal device is in, each paging network device needs to send the same paging content through the corresponding beam in all beam directions used to send SSBs. Moreover, each PF needs to scan all SSB beam directions, so the period of the PF = the SSB period. Accordingly, each UE wakes up in its own PF and PO to receive paging messages according to the period agreed in SIB1.
[0230] In one example, see Figure 7 , Figure 7This is a schematic diagram of detecting paging messages within a paging cycle, where s = 8, meaning that the network device has 8 beams for sending SSBs in a single SSB burst. Taking PO#0 as an example, there are 8 consecutive slots within PO, which means there are 8 consecutive PDCCH detection opportunities. In these 8 consecutive slots, the network device sends the same paging message sequentially to the direction of the 8 beams used for sending SSBs. Correspondingly, the terminal device monitors the 8 slots sequentially until it obtains its own paging message or has finished monitoring all 8 slots.
[0231] In the methods described above, because the network device does not know the location of the terminal device, it repeatedly sends the same paging message in all beam directions, resulting in wasted wireless resources, increased power consumption, increased paging delay, and potential interference, thus reducing system efficiency. To address these issues, two solutions are proposed below.
[0232] Both solutions rely on network devices transmitting SSBs and SIBs using beams with varying coverage areas. Specifically, network devices transmit SSBs using a "wide beam" (beam with a larger coverage area), further subdividing the signal coverage area of the SSB into multiple sub-regions. Within each sub-region, SIBs (e.g., SIB1 or SIB19) are transmitted using a "narrow beam" (beam with a smaller coverage area). In other words, network devices transmit SIBs using "region-level narrow beams." Each sub-region's SIB carries paging resource configuration information for that sub-region, including an SIB index. Network devices and terminal devices can determine the corresponding PMO for a sub-region based on this paging resource configuration information using a specific protocol. For example, this specific protocol could be an agreement on the correspondence between SIB indices and PMOs. In other words, the PO is subdivided into multiple PMOs, with one sub-region corresponding to one PMO. Network devices and terminal devices can send and monitor paging messages on one or more PMOs, eliminating the need to repeatedly send paging messages and monitor the entire PO.
[0233] The difference lies in the approach. In Solution 1, the SIB corresponding to a sub-area only carries the paging resource configuration information for that sub-area. That is, the SIB corresponding to a sub-area is associated with only one paging message. Accordingly, the network device needs to send the paging message on the PMO corresponding to the sub-area to which the terminal device belongs, and the terminal device monitors the paging message on the PMO corresponding to its own sub-area. In Solution 2, the SIB corresponding to a sub-area carries the paging resource configuration information for all sub-areas within the signal coverage area of the SSB to which that sub-area belongs. That is, the SIB corresponding to a sub-area is associated with N paging messages, where N refers to the number of sub-areas included in the signal coverage area of an SSB. Accordingly, the network device needs to send the paging message on the PMOs corresponding to each of the N sub-areas, including the sub-area to which the terminal device belongs, and the terminal device monitors the paging message on the PMOs corresponding to each of these N sub-areas until it hears it.
[0234] For solution approach 1, please refer to [link / reference]. Figure 8 , Figure 8 This is a schematic diagram illustrating the paging process when an SIB is associated with a paging message, as provided in an embodiment of this application. Figure 8 As shown, the signal coverage area corresponding to the SSB includes three sub-regions: region 0, region 1, and region 2. The network device sends the corresponding SIB1 / SIB19 to region 0, region 1, and region 2 through "region-level narrow beam 0", "region-level narrow beam 1", and "region-level narrow beam 2", respectively. That is, the coverage area of "region-level narrow beam 0" is region 0, the coverage area of "region-level narrow beam 1" is region 1, and the coverage area of "region-level narrow beam 2" is region 2. Among them, the SIB1 / SIB1 corresponding to each region carries the paging resource configuration information of the corresponding region. The terminal device performs initial access based on the acquired SSB and SIB1 / SIB19. This initial access process includes: the terminal device acquiring the SIB transmitted via a "regional narrow beam"; the terminal device sending a random access preamble via the physical random access channel (PRACH); the network device receiving the preamble and returning a random access response (RAR); the terminal device sending message 3 requesting an RRC connection; the network device sending message 4 for authorization and connection configuration; and the terminal device sending message 5 to confirm configuration completion and connection establishment. All information in this initial access phase is transmitted via a "regional narrow beam," such as... Figure 8As shown, the terminal device is located in area 2, so all information during the initial access phase is transmitted through "area-level narrow beam 2". After the terminal device completes the initial access, when a paging message is present, the network device determines the sub-area to which the terminal device belongs based on the terminal device's location information or the "area-level narrow beam" selected by the terminal device when initiating random access. Then, through this "area-level narrow beam," i.e., "area-level narrow beam 2," the network device sends a paging message carrying the terminal device's identification information (e.g., UE-ID) to the PMO corresponding to area 2. The terminal device monitors the PMO corresponding to area 2, and after receiving the paging message, responds to the paging and interacts with the network device through the "user-level narrow beam".
[0235] For solution approach 2, please refer to [link / reference]. Figure 9 , Figure 9 This is a schematic diagram illustrating the paging process when an SIB is associated with N paging messages, as provided in an embodiment of this application. Figure 9 As shown, the signal coverage area corresponding to the SSB includes three sub-regions: Region 0, Region 1, and Region 2. Network devices send the corresponding SIB1 / SIB19 to Regions 0, 1, and 2 via "Region-level Narrow Beam 0," "Region-level Narrow Beam 1," and "Region-level Narrow Beam 2," respectively. That is, the coverage area of "Region-level Narrow Beam 0" is Region 0, the coverage area of "Region-level Narrow Beam 1" is Region 1, and the coverage area of "Region-level Narrow Beam 2" is Region 2. Each region's corresponding SIB1 / SIB19 carries paging resource configuration information for the three regions (Region 0, Region 1, and Region 2). The terminal device performs initial access based on the acquired SSB and SIB1 / SIB19. The initial access process can be referenced from [reference needed]. Figure 8The relevant descriptions in the text will not be repeated here. When the terminal device has a paging message, the network device determines the sub-area to which the terminal device belongs and the signal coverage area corresponding to the SSB to which the sub-area belongs based on the location information of the terminal device or the "regional narrow beam" selected by the terminal device when initiating random access. The network device then sends a paging message to each sub-area within the signal coverage area corresponding to the SSB, that is, it sends a paging message carrying the terminal device identification information (e.g., UE-ID) to the PMO corresponding to region 0, the PMO corresponding to region 1, and the PMO corresponding to region 2 respectively through "regional narrow beam 0", "regional narrow beam 1", and "regional narrow beam 2". The terminal device sequentially monitors the PMO corresponding to region 0, the PMO corresponding to region 1, and the PMO corresponding to region 2. Upon obtaining its own paging message, it stops monitoring and responds to paging after obtaining the paging message, interacting with the network device through the "user-level narrow beam". In one possible implementation, the terminal device can also sequentially monitor the PMO corresponding to region 0, the PMO corresponding to region 1, and the PMO corresponding to region 2, that is, the terminal device does not stop monitoring after obtaining its own paging message.
[0236] In the above-mentioned solution 1, the terminal device determines the monitored PMO based on a defined "regional-level narrow beam" (which can be understood as the "regional-level narrow beam" corresponding to the sub-region to which the terminal device "believes" it belongs, or as the SIB received at the terminal device's location being transmitted through the "regional-level narrow beam," and this defined "regional-level narrow beam" is the "regional-level narrow beam" that transmits the SIB received by the terminal device) and performs paging reception within that PMO. However, when the terminal device moves, causing a change in the sub-region to which the terminal device belongs, and consequently a change in the monitored "regional-level narrow beam," monitoring only a specific PMO may miss paging, affecting paging performance. For example, if... Figure 10 As shown in (1), there are four sub-regions within the signal coverage area corresponding to the SSB transmitted via wide beam: sub-region 1, sub-region 2, sub-region 3, and sub-region 4. The UE is in sub-region 1. When the UE moves, for example, from sub-region 1 to the adjacent sub-region 2, if the UE continues to monitor only the PMO corresponding to sub-region 1, it will not receive its own paging message because the PMO sent by the paging message has now been changed to the PMO corresponding to sub-region 2.
[0237] In solution 2 above, the terminal device monitors all sub-areas corresponding to the PMOs within the signal coverage area of the SSB, ensuring paging is successful, but this incurs high overhead (high monitoring overhead for the terminal device and high transmission overhead for the network device). For example, ... Figure 10As shown in (2), there are four sub-regions within the signal coverage area corresponding to the SSB transmitted by the wide beam: sub-region 1, sub-region 2, sub-region 3 and sub-region 4. The UE is in sub-region 1. When the UE moves, for example from sub-region 1 to the adjacent sub-region 3, since the monitoring range of the terminal device is the four PMOs corresponding to the four sub-regions, it can still ensure that it can monitor the PMO corresponding to the current area, i.e., sub-region 3, and obtain the Paging message. However, at this time, the paging overhead of the network device is large (because the network device needs to send paging messages containing the UE-ID in multiple locations to ensure that the paging is successful), and the monitoring overhead of the terminal device is also large (because the terminal device needs to monitor multiple PMOs).
[0238] Based on this, the embodiments of this application propose the following solutions.
[0239] Please see Figure 11 , Figure 11 This is a schematic diagram of a communication method provided in an embodiment of this application. The method includes, but is not limited to, the following steps:
[0240] Step S1101: The network device sends the first message to the first area.
[0241] For example, a network device sends a first message to a first area, and correspondingly, a terminal device located within the first area receives the first message from the network device. The first message includes paging resource configuration information for the first area and paging resource configuration information for N adjacent areas, where N is greater than or equal to 1.
[0242] For example, the range of each region in the first region and the adjacent N regions is the signal coverage range corresponding to different System Message Blocks (SIBs); the first region is a sub-region of the second region, and the range of the second region is the signal coverage range corresponding to the synchronization signal block (SSB) or the master information block (MIB). Here, the SSB, MIB, and SIB are all transmitted by the network device via beams; in other words, the signal coverage ranges corresponding to the SSB, MIB, and SIB are respectively the coverage ranges of the beams used to transmit the SSB, MIB, and SIB. This process can be understood as the network device transmitting the SSB or MIB through a wide beam (a beam with a larger coverage range), where the signal coverage range corresponding to one SSB or MIB is a wide region (e.g., the second region is a wide region), and this wide region is further subdivided into multiple sub-regions. The network device transmits the SIB corresponding to each sub-region to each sub-region through a narrow beam (a beam with a smaller coverage range), where the signal coverage range corresponding to one SIB is a sub-region within a wide region (e.g., the first region is a sub-region within the second region). This process can also be understood as follows: a wide area corresponds to a wide beam used to transmit SSB, a sub-area corresponds to a narrow beam used to transmit SIB, and a wide area is subdivided into multiple sub-areas. Therefore, a wide beam used to transmit SSB is associated with multiple narrow beams used to transmit SIB.
[0243] In the above method, the signal coverage area corresponding to one SIB is taken as a sub-region. This is beneficial for subsequent network devices to carry the first message in the SIB and send it to the sub-region (first region), thereby achieving more targeted and refined paging scheduling, reducing interference, and improving paging success rate and paging efficiency. At the same time, sending the SSB with a beam with a larger coverage area improves network coverage and access probability, while sending the SIB with a beam with a smaller coverage area improves transmission reliability and resource efficiency.
[0244] For example, in the embodiments of this application, adjacent areas include signal coverage areas that are adjacent, or temporally adjacent. Optionally, when adjacent areas include signal coverage areas that are adjacent, the first area and the N adjacent areas may be located within areas corresponding to different SSBs or MIBs, that is, one or more of the N adjacent areas may not be sub-regions of the second area.
[0245] In one example, see Figure 12 , Figure 12This is a schematic diagram of a first region and adjacent regions provided in an embodiment of this application. The ranges of the second, third, and fourth regions are the signal coverage ranges corresponding to the SSB or MIB. Sub-regions within the second region include the first region, region 1, region 2, and region 3; sub-regions within the third region include region 4, region 5, region 6, and region 7; and sub-regions within the fourth region include region 8, region 9, region 10, and region 11. The ranges of the sub-regions within the second, third, and fourth regions are the signal coverage ranges corresponding to the SIB, meaning the granularity of the second, third, and fourth regions differs from that of their sub-regions. Regions 1, 3, 7, 8, and 9 are adjacent to the first region in terms of signal coverage area. Regions 1 and 3 are sub-regions of the second region, region 7 is a sub-region of the third region, and regions 8 and 9 are sub-regions of the fourth region. Therefore, the N adjacent regions include region 1, region 3, region 7, region 8, and region 9.
[0246] In another example, there are a first region and a region 12. The first region sends a paging message in the first time slot, and the paging message of region 12 is sent in the second time slot. The first time slot and the second time slot are adjacent in the time domain, so region 12 is adjacent to the first region in the time domain.
[0247] Optionally, the size of N can be determined by the network device in combination with the area size and the terminal device status, for example, such as Figure 12 As shown, the radius of the first region and the regions adjacent to the first region are both A, and the average moving speed of the terminal device is 3A. Then, the N adjacent regions include region 1, region 3, region 7, region 8 and region 9, and N = 5.
[0248] For example, the paging resource configuration information includes at least one of the following: the SIB identifier (SIB-ID) corresponding to the region, or the paging identifier (paging-ID) corresponding to the region.
[0249] In one example, the SIB-ID adopts a two-level indication form of an SSB index and a SIB index, where the SSB index is an integer greater than or equal to 0 and less than P, the SSB index is used to indicate the number of the beam for transmitting the SSB to which the SIB belongs, the SIB index is an integer greater than or equal to 0 and less than Q, where P refers to the number of SSBs transmitted by the network device in one burst of SSBs, and Q refers to the number of SIB-transmitting beams associated with one SSB-transmitting beam. In one example, one SSB-transmitting beam is associated with 2 SIB-transmitting beams, and the SIB-ID exists as SSB index=0 and SIB index=2. SSB index=0 and SIB index=2 indicate that the SIB corresponding to the SIB-ID is the SIB-transmitting beam #2 under the SSB-transmitting beam #0, that is, the SIB-transmitting beam numbered 2 associated with the SSB-transmitting beam numbered 0, that is, the third SIB-transmitting beam associated with the first SSB-transmitting beam.
[0250] In another example, the SIB-ID adopts a global indication form of a SIB index, that is, a unique SIB-ID is defined, which does not need to be distinguished by the SSB index, where the SIB index represents the number among the multiple SIB-transmitting beams associated with all SSB-transmitting beams. In one example, there are 2 SSB-transmitting beams, each SSB-transmitting beam is associated with 2 SIB-transmitting beams, SIB-ID 1 is SIB index=1, and SIB-ID 2 is SIB index=3. SIB index=1 indicates that the SIB corresponding to SIB-ID 1 is the second SIB-transmitting beam under the SSB-transmitting beam #0, that is, the second SIB-transmitting beam associated with the SSB-transmitting beam numbered 0, that is, the second SIB-transmitting beam associated with the first SSB-transmitting beam. SIB index=3 indicates that the SIB corresponding to SIB-ID 2 is the second SIB-transmitting beam under the SSB-transmitting beam #1, that is, the second SIB-transmitting beam associated with the SSB-transmitting beam numbered 1, that is, the second SIB-transmitting beam associated with the second SSB-transmitting beam.
[0251] Optionally, the paging resource configuration information of the first region and the N adjacent regions is presented in the form of a list, and correspondingly, the SIB-IDs or paging-IDs of the first region and the N adjacent regions are presented in the form of a list.
[0252] In the above method, the subsequent terminal device can determine the PMO corresponding to the region based on the SIB-ID and / or paging-ID in the paging resource configuration information of the region, thereby determining M candidate PMOs. This facilitates the subsequent terminal device to successfully monitor one or more of the M PMOs corresponding to the M regions, improves monitoring redundancy, and ensures monitoring performance.
[0253] For example, the first message is carried in the SIB or MIB corresponding to the first region. Optionally, the SIB carrying the first message can be SIB1 or SIB19. When the first message is carried in the MIB corresponding to the first region, the first message also includes paging resource configuration information for one or more sub-regions in the second region other than the first region, and paging resource configuration information for N regions adjacent to each of the one or more sub-regions. That is, the first message includes paging resource configuration information for each sub-region in the second region and the adjacent regions corresponding to each sub-region. It should be noted that the number N of adjacent regions may be equal or unequal for different sub-regions. In one example, such as... Figure 12 As shown, when the first message is carried in the MIB corresponding to the first region, the first message also includes the paging resource configuration message of region 1, the paging messages of N regions adjacent to region 1, the paging resource configuration message of region 2, the paging messages of N regions adjacent to region 2, the paging resource configuration message of region 3, and the paging messages of N regions adjacent to region 3.
[0254] In the above method, carrying the first message in the SIB corresponding to the first area is beneficial to achieve more targeted and refined paging scheduling, reduce interference, and improve paging success rate and paging efficiency; carrying the first message in the MIB corresponding to the first area enables the terminal device to obtain paging resource configuration information earlier, reducing the signaling interaction process for obtaining paging resource configuration information.
[0255] Optionally, the first message may further include first location information. Optionally, the first location information may include the location information of N regions adjacent to the first region, or the first location information may include the location information of the first region and the N regions adjacent to the first region.
[0256] For example, the location information of the N adjacent regions includes at least one of the following: the wave position of the beam corresponding to each of the N adjacent regions; the wave position center point of the wave position corresponding to each of the N adjacent regions; the beam center position of the beam corresponding to each of the N adjacent regions; the radius of each of the N adjacent regions; the arrangement of the N adjacent regions; and the angle information of each of the N adjacent regions.
[0257] For example, the position information of the first region and the N adjacent regions includes at least one of the following: the wavefront of the beam corresponding to each of the first region and the N adjacent regions; the wavefront center point of the wavefront corresponding to each of the first region and the N adjacent regions; the beam center position of the beam corresponding to each of the first region and the N adjacent regions; the radius of each of the first region and the N adjacent regions; the arrangement of the first region and the N adjacent regions; and the angle information of each of the first region and the N adjacent regions.
[0258] In the above method, the aforementioned approach facilitates the subsequent determination of the preferred PMO from M candidate PMOs for monitoring by the terminal device based on its own location information and the first location information. This ensures monitoring redundancy while further reducing the monitoring overhead of the terminal device, reducing power consumption, and improving monitoring efficiency.
[0259] In one possible implementation, before the network device sends the first message to the first area, the method further includes: the network device sending an SSB to the second area.
[0260] For example, the network device sends an SSB to a terminal device in the second area, and the terminal device in the second area receives the SSB from the network device.
[0261] For example, the network device parses the SSB to obtain the SSB index and the search space configuration information of the SIB (e.g., SIB1\SIB19), and then obtains the SIB based on the search space configuration information of the SIB, thereby obtaining the first message.
[0262] In one possible implementation, the method further includes: the terminal device randomly accessing the network via a Physical Random Access Channel (PRACH).
[0263] Step S1102: The network device sends paging messages to the first area and N areas adjacent to the first area.
[0264] For example, the network device sends paging messages to the first region and the N adjacent regions through the beams corresponding to the first region and the N adjacent regions, respectively. In one example, taking the first region as an example, the beam corresponding to the first region is the first beam, and the PMO corresponding to the first region is PMO 1. Then, the network device sends paging messages to the first region through the first beam in PMO 1.
[0265] In the above method, paging messages are sent through a beam with a smaller coverage area corresponding to the region, which reduces the coverage area, improves the transmission performance of data signals, and ensures monitoring performance.
[0266] Step S1103: The terminal device monitors one or more of the M physical downlink control channel monitoring occasions (PMOs) corresponding to the M regions.
[0267] The M regions include a first region and N regions adjacent to the first region. The PMO corresponding to each of the M regions is determined based on the paging resource configuration information of each region.
[0268] For example, the first region is a sub-region within the second region of S wide regions. Each of the S wide regions includes H sub-regions. The range of each wide region in the S wide regions is the signal coverage range corresponding to different SSBs or MIBs. S is an integer greater than or equal to 1, and H is an integer greater than or equal to 2. There are two ways to determine the PMO corresponding to a region based on the region's paging resource configuration information, as follows:
[0269] Method (1): When the paging resource configuration information of a region indicates that the region is the h-th sub-region of the K-th wide region among the S wide regions, the PMO corresponding to the region is the (h-1)×S+K-th PMO.
[0270] In one example, if the number of SSBs sent by a network device in an SSB burst is 4, that is, the number of wide areas S = 4, and one beam used to send SSBs is associated with 3 beams used to send SIBs, that is, the number of sub-areas included in a wide area H = 3, then the PMO corresponding to the first sub-area in the first wide area is the first PMO, the PMO corresponding to the second sub-area in the first wide area is the fifth PMO, and the PMO corresponding to the third sub-area in the first wide area is the ninth PMO.
[0271] Method (2): When the paging resource configuration information of a region indicates that the region is the h-th sub-region of the K-th wide region among the S wide regions, the PMO corresponding to the region is the (K-1)×H+(h-1)-th PMO.
[0272] In one example, if the number of SSBs sent by a network device in an SSB burst is 4, that is, the number of wide areas S = 4, and one beam used to send SSBs is associated with 3 beams used to send SIBs, that is, the number of sub-areas included in a wide area H = 3, then the PMO corresponding to the first sub-area in the first wide area is the first PMO, the PMO corresponding to the second sub-area in the first wide area is the second PMO, and the PMO corresponding to the third sub-area in the first wide area is the third PMO.
[0273] Where K is an integer greater than or equal to 1 and not greater than S, and h is an integer greater than or equal to 1 and not greater than H.
[0274] In the above method, the determination relationship of PMO is defined, which enables the terminal device to determine the PMO corresponding to the region, thereby enabling the terminal device to accurately receive paging messages and ensure monitoring performance.
[0275] In one possible implementation, the terminal device monitors one or more of M PMOs. In one example, the terminal device monitors the M PMOs sequentially in a certain order (e.g., chronological order, PMO number order). When the terminal device detects its own paging message, it stops monitoring the remaining PMOs. For example, see [link to relevant documentation]. Figure 13 , Figure 13 This is a schematic diagram of a terminal device monitoring one or more PMOs out of M PMOs, as provided in an embodiment of this application. Figure 13As shown, when the terminal device receives the first message, it is located in the first region. The first message includes the paging resource configuration information of the first region and the paging resource configuration information of the five regions (region 1, region 3, region 7, region 8, and region 9) adjacent to the first region. The PMOs corresponding to the first region, region 1, region 3, region 7, region 8, and region 9 are PMO 1, PMO 2, PMO 3, PMO 4, PMO 5, and PMO 6, respectively. Subsequently, the terminal device moves from the first region to region 3. The terminal device monitors the PMOs in ascending order of their numbers. When the terminal device detects its own paging message in PMO 3 (the PMO corresponding to region 3), the terminal device no longer monitors the remaining PMOs 4, PMO 5, and PMO 6. That is, the terminal device monitors three of the six PMOs (PMO 1, PMO 2, and PMO 3). In another example, a subset of PMOs can be selected from M PMOs according to pre-defined rules. Monitoring of these selected PMOs is then performed, stopping once a PMO is detected. This process can be understood as follows: the network device provides the terminal device with M candidate PMOs, which represent the PMOs corresponding to the first region and the N regions adjacent to it. The terminal device monitors these M candidate PMOs sequentially according to a certain order. Alternatively, the terminal device can filter these M candidate PMOs according to pre-defined rules, selecting the more accurate (or more likely to detect paging messages) PMOs, and then monitoring these more accurate PMOs sequentially according to a certain order.
[0276] In another possible implementation, the first message also includes first location information, and the terminal device monitors one or more PMOs among the M PMOs corresponding to the M regions respectively, including: the terminal device monitors one or more PMOs corresponding to the M regions respectively, and the one or more regions are regions determined from the M regions based on the first location information and the terminal's own location information.
[0277] The above process can be understood as follows: the network device provides the terminal device with M candidate PMOs. These M candidate PMOs are the PMOs corresponding to the first region and the N regions adjacent to the first region. Based on its own location information and the first location information, the terminal device determines which region(s) it is within the first region and the N regions adjacent to the first region, thereby filtering out the region where the terminal device is more likely to be located. Then, the terminal device monitors the PMOs corresponding to the filtered regions where it is more likely to be located, thus achieving the purpose of determining the preferred PMO from the M candidate PMOs.
[0278] The number of these one or more regions (i.e., the number of regions that the terminal device is more likely to be located in) can be determined by the terminal device based on the location information error. For example, if the error of the terminal device's location information is within a few meters, the terminal device can accurately determine that it is located in one or more regions. In this case, the terminal device can reduce the number of these one or more regions, or even be precise to a single region. However, if the error of the terminal device's location information is tens or even hundreds of meters, more candidate regions need to be retained to avoid missing the PMO corresponding to the actual location.
[0279] It should be noted that the terminal device monitors the PMOs corresponding to the one or more regions respectively, which is the same as the terminal device monitoring one or more PMOs out of M PMOs mentioned above. It can also be understood that the terminal device monitors them in a certain order. When the terminal device detects its own paging message, it stops monitoring the remaining PMOs.
[0280] In one example, see Figure 14 , Figure 14 This is a schematic diagram of a terminal device monitoring one or more PMOs corresponding to different areas, as provided in an embodiment of this application. Figure 14 As shown, when the terminal device receives the first message, it is located in the first region. The first message includes paging resource configuration information of the first region, paging resource configuration information of five regions (region 1, region 3, region 7, region 8, and region 9) adjacent to the first region, and first location information. The first location information includes the location information of the first region and the five adjacent regions. Subsequently, the terminal device moves from the first region to region 7. Based on its own location information and the first location information, the terminal device determines that it is currently located in region 7. Then, the terminal device selects three regions corresponding to PMOs for monitoring. These three regions are the first region, region 7, and region 9. Finally, the terminal device monitors the PMO corresponding to the first region, the PMO corresponding to region 7, and the PMO corresponding to region 9 in a certain order. When the terminal device detects its own paging message, it stops monitoring the remaining PMOs.
[0281] In the above method, the terminal device can determine the preferred PMO from M PMOs based on its own location information and the first location information, which ensures monitoring redundancy while further reducing the monitoring overhead of the terminal device, reducing power consumption, improving monitoring efficiency, and thus enhancing the user experience.
[0282] In one possible implementation, the method further includes: the terminal device acquiring a paging message.
[0283] For example, the terminal device sequentially monitors the PMO and obtains the paging messages within the PMO.
[0284] For example, the paging message includes the identification information of the terminal device (UE-ID).
[0285] For example, the terminal device determines whether the paging message is its own paging message based on the UE-ID in the paging message. For instance, if the UE-ID in the paging message matches the terminal device's own UE-ID, it means that the paging message is the terminal device's own paging message. If the UE-ID in the paging message does not match the terminal device's own UE-ID, it means that the paging message is not the terminal device's own paging message, and the terminal device ignores the paging message.
[0286] In one possible implementation, the method further includes: the terminal device demodulating the paging message.
[0287] For example, the terminal device demodulates the paging message based on the paging resource configuration information of the first region and the resource configuration information of the N adjacent regions, and performs the next operation according to the paging purpose indicated by the paging message.
[0288] exist Figure 11 In the described method, the network device sends the paging resource configuration information of the first area and the paging resource configuration information of N adjacent areas to the first area. The terminal device can determine a limited number of PMOs (PMOs corresponding to the first area and the N adjacent areas) based on the paging resource configuration information of the first area and the paging resource configuration information of the N adjacent areas, and perform monitoring. This improves monitoring redundancy and ensures monitoring performance. At the same time, compared with the terminal device monitoring PO, the terminal device consumes less monitoring overhead to monitor multiple PMOs, reduces power consumption, and improves monitoring efficiency.
[0289] Please see Figure 15 , Figure 15 This is a schematic diagram of another communication method provided in an embodiment of this application, which includes, but is not limited to, the following steps:
[0290] Step S1501: The network device sends a second message to the second area.
[0291] For example, a network device sends a first message to a second region, and correspondingly, a terminal device located within the second region receives a second message from the network device. The second message includes paging resource configuration information and location information for each sub-region within at least two regions, including the second region and a third region adjacent to the second region.
[0292] For example, the range of the at least two regions is the signal coverage range corresponding to different Synchronization Message Blocks (SSBs) or Master Message Blocks (MIBs), and the range of each sub-region within the at least two regions is the signal coverage range corresponding to different System Message Blocks (SIBs). Here, the SSBs, MIBs, and SIBs are all transmitted by the network device via beams; in other words, the signal coverage ranges corresponding to the SSBs, MIBs, and SIBs are respectively the coverage ranges of the beams used to transmit the SSBs, MIBs, and SIBs. This process can be understood as the network device transmitting SSBs or MIBs through a wide beam (a beam with a larger coverage range), where the signal coverage range corresponding to one SSB or MIB is a wide area (e.g., each region within the at least two regions is a wide area). This wide area is further subdivided into multiple sub-regions, and the network device transmits the SIBs corresponding to each sub-region to each sub-region through a narrow beam (a beam with a smaller coverage range). The signal coverage range corresponding to one SIB is a sub-region within a wide area (e.g., each sub-region within the at least two regions is a sub-region within a certain wide area). This process can also be understood as follows: a wide area corresponds to a wide beam for transmitting SSBs, and a sub-area corresponds to a narrow beam for transmitting SIBs. A wide area is subdivided into multiple sub-areas, thus a wide beam for transmitting SSBs is associated with multiple narrow beams for transmitting SIBs. In the above method, transmitting SSBs using a beam with a larger coverage area improves network coverage and access probability, while transmitting SIBs using a beam with a smaller coverage area improves transmission reliability and resource efficiency.
[0293] It should be noted that, in addition to the second and third regions mentioned above, the at least two regions may also include more regions adjacent to the second region. The above only uses the second and third regions as examples, and the embodiments of this application are not limited thereto.
[0294] For example, in the embodiments of this application, "adjacent" includes being adjacent in the coverage area of the signal, or adjacent in the time domain. In one example, such as Figure 12As shown, the second and third regions, and the second and fourth regions, are adjacent in terms of signal coverage area. In another example, there are a second and a fifth region, the range of which is the signal coverage area corresponding to the SSB or MIB, and the sub-regions within the second and fifth regions are the signal coverage areas corresponding to the SIB. Specifically, the sub-regions within the second region are sub-region 1, sub-region 2, and sub-region 3, respectively. The PMO corresponding to sub-region 1 is PMO 1, the PMO corresponding to sub-region 2 is PMO 2, and the PMO corresponding to sub-region 3 is PMO 3. PMO 1, PMO 2, and PMO 3 all belong to the first time unit group; that is, the "PMOs" (PMO 1, PMO 2, and PMO 3) corresponding to the second region are the first time unit group. Similarly, the sub-regions in the fifth region are sub-region 4, sub-region 5, and sub-region 6, respectively. The PMO corresponding to sub-region 4 is PMO 4, the PMO corresponding to sub-region 5 is PMO 5, and the PMO corresponding to sub-region 6 is PMO 6. PMO 4, PMO 5, and PMO 6 all belong to the second time unit group. That is, it can be understood that the "PMOs" (PMO 4, PMO 5, and PMO 6) corresponding to the fifth region are the second time unit group. The first time unit group belongs to the first time resource, and the second time unit group belongs to the second time resource. The first time resource and the second time resource are adjacent in the time domain. Therefore, the fifth region and the second region are adjacent in the time domain.
[0295] In the above method, the network device can provide paging resource configuration information for each sub-region in at least two regions (the second region and the third region adjacent to the second region), thereby enabling the subsequent terminal device to determine multiple candidate PMOs (PMOs corresponding to each sub-region) for monitoring, improving monitoring redundancy and ensuring monitoring performance.
[0296] For example, the paging resource configuration information includes at least one of the following: the SIB identifier (SIB-ID) corresponding to the sub-region, or the paging identifier (paging-ID) corresponding to the sub-region.
[0297] In an example, the SIB-ID adopts a two-level indication form of an SSB index and a SIB index, where the SSB index is an integer greater than or equal to 0 and less than P, the SSB index is used to indicate the number of the beam for transmitting the SSB to which the SIB belongs, the SIB index is an integer greater than or equal to 0 and less than Q, P refers to the number of SSBs transmitted by the network device in one burst of SSBs, and Q refers to the number of beams for transmitting SIBs that are associated with one beam for transmitting SSBs. In an example, one beam for transmitting SSBs is associated with 2 beams for transmitting SIBs, and there exists a SIB-ID with SSB index=0 and SIB index=2. The SSB index=0 and SIB index=2 indicate that the SIB corresponding to the SIB-ID is the beam #2 for transmitting SIB under the beam #0 for transmitting SSB, that is, the beam numbered 2 for transmitting SIB associated with the beam numbered 0 for transmitting SSB, that is, the third beam for transmitting SIB associated with the first beam for transmitting SSB.
[0298] In another example, the SIB-ID adopts a global indication form of a SIB index, that is, a unique SIB-ID is defined, and no distinction needs to be made through the SSB index, where the SIB index indicates the number among the multiple beams for transmitting SIBs associated with all beams for transmitting SSBs. In an example, there are 2 beams for transmitting SSBs, each beam for transmitting SSBs is associated with 2 beams for transmitting SIBs, and there exists SIB-ID 1 with SIB index=1 and SIB-ID 2 with SIB index=3, where SIB index=1 indicates that the SIB corresponding to SIB-ID 1 is the second beam for transmitting SIB under the beam #0 for transmitting SSB, that is, the second beam for transmitting SIB associated with the beam numbered 0 for transmitting SSB, that is, the second beam for transmitting SIB associated with the first beam for transmitting SSB, and SIB index=3 indicates that the SIB corresponding to SIB-ID 2 is the second beam for transmitting SIB under the beam #1 for transmitting SSB, that is, the second beam for transmitting SIB associated with the beam numbered 1 for transmitting SSB, that is, the second beam for transmitting SIB associated with the second beam for transmitting SSB.
[0299] Optionally, the paging resource configuration information of each sub-region in at least two regions is presented in the form of a list, and correspondingly, the SIB-IDs or paging-IDs of each sub-region in the at least two regions are presented in the form of a list.
[0300] In the above method, the above approach helps the subsequent terminal device to determine the PMO corresponding to the sub-region based on the SIB-ID and / or paging-ID in the paging resource configuration information of the sub-region, thereby determining multiple candidate PMOs (PMOs corresponding to each sub-region), improving monitoring redundancy, and ensuring monitoring performance.
[0301] For example, the position information of each sub-region in the at least two regions includes at least one of the following: the wave position of the beam corresponding to each sub-region in the at least two regions; the wave position center point of the wave position corresponding to each sub-region in the at least two regions; the beam center point of the beam corresponding to each sub-region in the at least two regions; the reference point of the beam / wave position corresponding to each sub-region in the at least two regions; the radius of each sub-region in the at least two regions; the arrangement of each sub-region in the at least two regions; and the angle information of each sub-region in the at least two regions.
[0302] Optionally, the location information of each sub-region in the at least two regions may further include at least one of the following: the relative position of each region in the at least two regions, the wave position of the beam corresponding to each region in the at least two regions, the wave position center point of the wave position corresponding to each region in the at least two regions, the beam center point of the beam corresponding to each region in the at least two regions, the radius of each region in the at least two regions, and the number of sub-regions included in each region in the at least two regions.
[0303] In the above method, the terminal device can determine the PMO corresponding to the sub-region based on the paging resource configuration information of the sub-region, which helps the terminal device to efficiently determine the PMO corresponding to the sub-region, thereby determining multiple candidate PMOs (PMOs corresponding to each sub-region), improving monitoring redundancy, and ensuring monitoring performance.
[0304] For example, the second message carries the synchronization signal block SSB, master signal block MIB, or extended master information block (MIB-E) corresponding to the second region.
[0305] For example, the second message is carried in the MIB-E, which also carries system messages necessary for access, such as random access channel occasion (RO) resource configuration information, network device location information, uplink transmission common configuration, random access channel (RACH) common configuration information, and downlink transmission common configuration. In the above method, the terminal device can obtain paging resource configuration information earlier, reducing the signaling interaction process for obtaining paging resource configuration information.
[0306] In one possible implementation, the method further includes: the terminal device sending a Physical Random Access Channel (PRACH) to randomly access the network.
[0307] Step S1502: The network device sends paging messages to each sub-area in at least two areas.
[0308] For example, the network device transmits paging messages through beams corresponding to each sub-region in at least two regions. In one example, such as Figure 12 As shown, taking region 1 in the second region as an example, the beam corresponding to region 1 is the first beam, and the PMO corresponding to region 1 is PMO1. Then, the network device sends a paging message to region 1 through the first beam in PMO 1.
[0309] In the above method, paging messages are sent through beams with smaller coverage areas corresponding to sub-regions, which reduces the coverage area, improves the transmission performance of data signals, and ensures monitoring performance.
[0310] Step S1503: The terminal device monitors the PMO corresponding to one or more sub-regions respectively.
[0311] The one or more sub-regions are sub-regions determined from the sub-regions included in at least two regions based on the location information of the terminal device itself and the location information of each sub-region in at least two regions. The PMO corresponding to each of the one or more sub-regions is determined based on the paging resource configuration information of the one or more sub-regions.
[0312] For example, the at least two regions are at least two wide regions out of S wide regions. Each of the S wide regions includes H sub-regions. The range of each wide region in the S wide regions is the signal coverage range corresponding to different SSBs or MIBs. S is an integer greater than or equal to 1, and H is an integer greater than or equal to 2. There are two ways to determine the PMO corresponding to the sub-region based on the paging resource configuration information of the sub-region, as follows:
[0313] Method (1): When the paging resource configuration information of a sub-region indicates that the sub-region is the h-th sub-region in the K-th wide region of the S wide regions, the PMO corresponding to the sub-region is the (h-1)×S+K-th PMO.
[0314] In one example, if the number of SSBs sent by a network device in an SSB burst is 4, that is, the number of wide areas S = 4, and one beam used to send SSBs is associated with 3 beams used to send SIBs, that is, the number of sub-areas included in a wide area H = 3, then the PMO corresponding to the first sub-area in the first wide area is the first PMO, the PMO corresponding to the second sub-area in the first wide area is the fifth PMO, and the PMO corresponding to the third sub-area in the first wide area is the ninth PMO.
[0315] Method (2): When the paging resource configuration information of a sub-region indicates that the sub-region is the h-th sub-region in the K-th wide region of the S wide regions, the PMO corresponding to the region is the (K-1)×H+(h-1)-th PMO.
[0316] In one example, if the number of SSBs sent by a network device in an SSB burst is 4, that is, the number of wide areas S = 4, and one beam used to send SSBs is associated with 3 beams used to send SIBs, that is, the number of sub-areas included in a wide area H = 3, then the PMO corresponding to the first sub-area in the first wide area is the first PMO, the PMO corresponding to the second sub-area in the first wide area is the second PMO, and the PMO corresponding to the third sub-area in the first wide area is the third PMO.
[0317] Where K is an integer greater than or equal to 1 and not greater than S, and h is an integer greater than or equal to 1 and not greater than H.
[0318] In the above method, the determination relationship of PMO is defined, which enables the terminal device to determine the PMO corresponding to the region, thereby enabling the terminal device to accurately receive paging messages and ensure monitoring performance.
[0319] The above process can be understood as follows: the network device provides the terminal device with multiple candidate PMOs, which are the PMOs corresponding to each sub-region in at least two regions. Based on its own location information and the location information of each sub-region in at least two regions, the terminal device determines which sub-region(s) it is located in, thereby filtering out the sub-region in which the terminal device is more likely to be located. Then, the terminal device monitors the PMOs corresponding to the filtered sub-region in which it is more likely to be located, thus achieving the purpose of determining the preferred PMO from multiple candidate PMOs.
[0320] The number of these one or more sub-regions (i.e., the number of sub-regions that the terminal device is more likely to be located in) can be determined by the terminal device based on the location information error. For example, if the error of the terminal device's own location information is within a few meters, the terminal device can accurately determine that it is located in one or more sub-regions. In this case, the terminal device can reduce the number of these one or more sub-regions, or even be precise to a single sub-region. However, if the error of the terminal device's own location information is tens of meters or even hundreds of meters, more candidate sub-regions need to be retained to avoid missing the PMO corresponding to the actual sub-region.
[0321] In one possible implementation, the terminal device monitors the PMOs corresponding to one or more sub-regions. This can be understood as the terminal device monitoring the PMOs corresponding to the one or more sub-regions sequentially in a certain order (e.g., chronological order, PMO number order). When the terminal device detects its own paging message, it stops monitoring the remaining PMOs. For example, if there are 5 PMOs, namely PMO 1, PMO 2, PMO 3, PMO 4, and PMO 5, the terminal device monitors these 5 PMOs sequentially in ascending order of their numbers. When the terminal device detects its own paging message in PMO 3, it stops monitoring the remaining PMOs 4 and 5; that is, the terminal device monitors 3 out of the 5 PMOs.
[0322] In one example, see Figure 16 , Figure 16 This is a schematic diagram of another terminal device monitoring one or more PMOs corresponding to different areas, as provided in the embodiments of this application. Figure 16As shown, the at least two regions include a second region, a third region, and a fourth region. The third and fourth regions are adjacent to the second region. The sub-regions in the second region include sub-region 1, sub-region 2, sub-region 3, and sub-region 4. The sub-regions in the third region include sub-region 5, sub-region 6, sub-region 7, and sub-region 8. The sub-regions in the fourth region include sub-region 9, sub-region 10, sub-region 11, and sub-region 12. When the terminal device receives the second message, it is located in sub-region 1. The first message includes the pa of each sub-region (sub-region 1 to sub-region 12) in the second, third, and fourth regions. After the terminal device receives the resource configuration information and location information, it moves from the sub-region to the sub-region 8. Based on its own location information and the location information of each sub-region, the terminal device determines that it is currently located in the sub-region 8. Then, the terminal device selects three PMOs corresponding to the sub-regions 1, 8 and 9 for monitoring. Finally, the terminal device monitors the PMOs corresponding to sub-region 1, sub-region 8 and sub-region 9 in a certain order. Once the terminal device detects its own paging message, it stops monitoring the remaining PMOs.
[0323] In one possible implementation, the method further includes: the terminal device acquiring a paging message.
[0324] For example, the terminal device sequentially monitors the PMO and obtains the paging messages within the PMO.
[0325] For example, the paging message includes the identification information of the terminal device (e.g., UE-ID).
[0326] For example, the terminal device determines whether the paging message is its own paging message based on the UE-ID in the paging message. For instance, if the UE-ID in the paging message matches the terminal device's own UE-ID, it means that the paging message is the terminal device's own paging message. If the UE-ID in the paging message does not match the terminal device's own UE-ID, it means that the paging message is not the terminal device's own paging message, and the terminal device ignores the paging message.
[0327] In one possible implementation, the method further includes: the terminal device demodulating the paging message.
[0328] For example, the terminal device demodulates the paging message based on the resource configuration information of each sub-region in at least two regions, and performs the next operation according to the paging purpose indicated by the paging message.
[0329] exist Figure 15In the described method, the network device sends paging resource configuration information and location information of each sub-region in at least two regions to the second region. The terminal device determines multiple candidate PMOs (PMOs corresponding to each sub-region) based on the paging resource configuration information of each sub-region, thereby improving monitoring redundancy and ensuring monitoring performance. Furthermore, the terminal device determines one or more sub-regions from the sub-regions included in the at least two regions based on its own location information and the location information of each sub-region in the at least two regions. The PMOs corresponding to the one or more sub-regions are the preferred PMOs among the multiple candidate PMOs, so that the terminal device can monitor only the PMOs corresponding to the one or more sub-regions. While improving monitoring redundancy and ensuring monitoring performance, this method further reduces monitoring overhead, lowers power consumption, improves monitoring efficiency, and enhances user experience.
