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

[0003] In a non-terrestrial network (NTN) communication system, due to the limitation of satellite manufacturing and launch cost, the on-board data processing capability and transmission power are limited. Currently, NTN cannot provide a communication rate comparable to terrestrial network (TN).

[0004] Since the coverage of the actual ground base station is limited, there will be many TN device and NTN device coexistence scenarios. For future NTN devices, the main target scenario is to supplement coverage and provide places that TN devices cannot cover. In order to realize the integrated design of TN and NTN, one of the problems to be solved is the interference problem caused by the coexistence of TN and NTN. For example, the interference of TN devices to the terminal devices served by NTN devices, and the interference of NTN devices to the terminal devices served by TN devices.

[0005] Therefore, it is urgent to provide a method to avoid the interference caused by the coexistence of TN and NTN. SUMMARY

[0006] The present application provides a communication method and related apparatus, which is beneficial to reduce the interference in the TN and NTN coexistence scenario.

[0009] In a TN-NTN coexistence scenario, based on the technical solution of the present application, the first TN device can send the location information of the first electronic fence to the first NTN device, so that the first NTN device can perform interference avoidance on the terminal device served by the TN device within the region surrounded by the first electronic fence, which is beneficial to reduce the interference of the NTN device on the terminal device served by the TN device in the TN-NTN coexistence scenario, and further beneficial to improve the throughput of the terminal device served by the TN device.

[0010] The NTN device comprises a communication device deployed in the air, such as a satellite, a high-altitude platform, etc. The TN device comprises an access network device deployed on the ground, such as a ground base station.

[0011] The electronic fence can be regarded as a virtual boundary of a region, which surrounds the region. In a TN-NTN coexistence scenario, the NTN device cannot send a beam within the electronic fence of the TN device, and the NTN device can only send a beam outside the electronic fence of the TN device.

[0012] In combination with the first aspect, in some implementations of the first aspect, the location information of the first electronic fence comprises beam position information in which the first electronic fence is located.

[0013] In combination with the first aspect, in some implementations of the first aspect, the beam position information comprises a single-level beam position index, or a multi-level beam position index.

[0015] With reference to the first aspect, in some implementations of the first aspect, the method further includes: determining a level of the electronic fence; and sending the level of the electronic fence to the at least one TN device.

[0016] With reference to the first aspect, in some implementations of the first aspect, before determining the level of the electronic fence, the method further includes: receiving first information, the first information being used to indicate the level of the electronic fence, or being used to indicate the number of the at least one TN device.

Hereinafter, the method is described by taking the case where it is applied to a first NTN device.

[0019] The method includes: receiving position information of a first electronic fence, the first NTN device being unable to send beams within the first electronic fence; and performing interference avoidance on terminal devices served by TN devices based on the position information of the first electronic fence.

[0020] In a TN-NTN coexistence scenario, based on the technical solution of the present application, the first NTN device can receive the position information of the first electronic fence from the first TN device, so that the first NTN device can perform interference avoidance on terminal devices served by TN devices within the area surrounded by the first electronic fence, which is conducive to reducing the interference of the NTN device on the terminal devices served by the TN device in the TN-NTN coexistence scenario, and further conducive to improving the throughput of the terminal devices served by the TN device.

[0021] With reference to the second aspect, in some implementations of the second aspect, performing interference avoidance on terminal devices served by TN devices based on the position information of the first electronic fence includes: adjusting the pointing direction of the beam to send the beam outside the first electronic fence, or turning off the beam that is expected to be sent into the first electronic fence. In this way, the first NTN device does not send beams into the first electronic fence, which is conducive to reducing the interference of the NTN device on the terminal devices served by the TN device, and further conducive to avoiding resource waste, thereby improving resource utilization.

[0022] With reference to the second aspect, in some implementations of the second aspect, the location information of the first electronic fence comprises berth information where the first electronic fence is located.

[0030] In the scenario where the NTN and the TN coexist, based on the technical solution of the present application, the first NTN device sends second information, i.e., information for interference coordination, to the first TN device. In this way, the first TN device can perform interference avoidance for the terminal device served by the at least one NTN device based on the second information when performing user scheduling, which is beneficial to reduce the interference of the TN device on the terminal device served by the NTN device in the TN and NTN coexistence scenario, and further beneficial to improve the throughput of the terminal device served by the NTN device.

[0034] In combination with the fourth aspect, in some implementations of the fourth aspect, performing interference avoidance for the terminal device served by the at least one NTN device based on the second information includes: taking the second information as an input of a scheduler to perform user scheduling. In this way, the beams in the coverage area of the at least one NTN device can be avoided when selecting beams, so as to be beneficial to reduce the interference of the TN device on the terminal device served by the at least one NTN device.

[0075] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0076] Before introducing the communication method and related apparatus provided by the embodiments of the present application, the following points will be explained first.

[0077] First, in the embodiments shown below, each term and English abbreviation, such as electronic fence, wave position, TN device, NTN device, etc., are exemplary examples given for convenience of description, and should not constitute any limitation on the present application. The present application does not exclude the possibility of defining other terms capable of achieving the same or similar functions in existing or future protocols.

[0078] Second, in the embodiments shown below, the first, second and various numerical numbers are only convenient for distinguishing the same or similar items with basically the same function and effect, and do not limit the sequence, and do not limit the scope of the embodiments. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not necessarily mean different.

[0079] Third, "at least one" means one or more, and "multiple" means two or more. The association relationship of "and / or" describing the associated objects means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or the like means any combination of these items, including any combination of single or multiple items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or multiple.

[0080] Fourth, in this application, "indication" can include direct indication and indirect indication, and can include explicit indication and implicit indication, and can include determination. The information indicated by a certain information / message is called to-be-indicated information, and there are many ways to indicate the to-be-indicated information in the specific implementation process, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or the index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship; only a part of the to-be-indicated information can be indicated, and the other part of the to-be-indicated information is known or agreed in advance, for example, the arrangement order of each information can be used to indicate a specific information, thereby reducing the indication overhead to a certain extent. The specific way of indication is not limited in this application. It can be understood that for the sender of the indication information, the indication information can be used to indicate the to-be-indicated information, and for the receiver of the indication information, the indication information can be used to determine the to-be-indicated information.

[0081] Fifth, in the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending a first message to a first terminal device" can be understood as the destination of the first message being the first terminal device, which can include direct transmission over the air interface, or indirect transmission over the air interface by other units or modules. "Receiving a first message from a first satellite" can be understood as the source of the first message being the first satellite, which can include direct reception from the first satellite over the air interface, or indirect reception from the first satellite over the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface.

[0082] In other words, sending and receiving can be between devices, such as between terminal devices and satellite devices, or within a device, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0083] Sixth, in the present application, "when", "if" and "if" all refer to the device making corresponding processing under certain objective conditions, and are not limited to time, nor do they require the device to have a judgment action when implemented, nor do they imply other limitations. Unless otherwise specified, "if" and "if" can be replaced, and "when" and "in the case of" can be replaced. "When" and "if" / "if" can be replaced.

[0084] Seventh, in the present application, the words "exemplary" or "for example" are used to indicate an example, illustration or description. Any embodiment or design scheme described as "exemplary" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the use of "exemplary" or "for example" is intended to present the relevant concept in a specific manner.

[0101] It should also be understood that the network device and the terminal device in the embodiments of the present application can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; or deployed on water; or deployed on aircraft, balloons, and satellites in the air. The embodiments of the present application do not limit the application scenarios of the network device and the terminal device.

[0102] The RAN of the present application can be an open RAN (open-RAN, or O-RAN). In the O-RAN, multiple network devices cooperate to assist a terminal device to implement wireless access, and different network devices respectively implement part of the functions of a base station. For example, a network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0103] FIG. 6 is a schematic diagram of an architecture of an O-RAN. The O-RAN system can include more or fewer components than those shown in FIG. 6, which is not limited in the present application. As shown in FIG. 6, the O-RAN includes a BBU, and optionally, the O-RAN also includes an RU. The BBU communicates with the CN through a backhaul link, the BBU communicates with the RU through a front-haul link, and the RU communicates with the terminal through an air interface. The BBU and the RU can be co-located or not co-located.

[0104] The BBU includes at least one CU and at least one DU, and the at least one CU communicates with the at least one DU through at least one midhaul link.

[0105] In the O-RAN system, part of the functions of the protocol layer are centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer are distributed in the DU and controlled by the CU.

[0106] In the present application, the first satellite indicating the reference position to the terminal device can also be implemented by the CU or the DU. For example, the CU and / or the DU are deployed on the first satellite, and the reference position is indicated to the terminal device by the CU or the DU.

[0107] FIG. 7 is a schematic diagram of a possible application framework of O-RAN in a communication system. O-RAN proposes an open-standard and interface-based RAN architecture, which decomposes the RAN into three main functional layers: CU, DU, and RU. These functional layers can be connected through open interfaces to achieve interoperability between devices of different manufacturers. O-RAN also introduces virtualization technology to decouple RAN functions from dedicated hardware and deploy them on open hardware and cloud platforms, thus achieving softwareization and flexibility of the RAN. In addition, O-RAN also utilizes artificial intelligence (AI) technology to integrate a RAN intelligent controller (RIC) into the RAN. As shown in FIG. 7, the communication system includes a RIC, which can be an AI module, for example, for implementing AI-related functions. The RIC includes a near-real time RIC (near-RT RIC) and a non-real time RIC (Non-RT RIC). The non-real time RIC mainly processes non-real-time information, such as data that is not sensitive to latency, which can be on the order of seconds. The near-real time RIC mainly processes near-real-time information, such as data that is relatively sensitive to latency, which can be on the order of tens of milliseconds. Real-time monitoring, optimization, and management of the RAN are achieved.

[0108] The main difference between O-RAN and traditional RAN is that the wireless system equipment is divided into standard subsystem component layers and developed independently, and the internal interface is opened as a means to achieve layer decoupling and interconnection between different manufacturers. It includes O-Cloud, RU, DU, CU-CP, CU-UP, RIC, and other different components, and through the establishment of a unified testing and certification mechanism, the compatibility and consistency between Open RAN components provided by different manufacturers are ensured.

[0109] The standards formulated by O-RAN are a supplement and enhancement of the 3rd generation partnership project (3GPP) standards. For example, based on the E1, F1, NG, Xn, X2, and other interfaces defined by 3GPP, O-RAN further opens and defines O1, O2, E2, A1, Open-FH, and other interfaces.

[0110] The related technologies and concepts involved in the present application are introduced below.

[0111] 1、Satellite communication system

[0112] Currently, 5G NR has entered the commercial deployment stage from the standardization stage. The NR standard is designed for the characteristics of terrestrial communication and has the characteristics of providing high-speed, high-reliability, and low-latency communication for terminal devices. Compared with the ground communication system, the NTN communication has the characteristics of large coverage area and flexible networking. Currently, multiple standard organizations are involved in the research of NTN communication technology and standards, trying to build a unified communication network for space, air, and ground communication.

[0113] To support wider service coverage, a network device can need to provide network services for a larger communication area. Taking the NTN communication system as an example, each satellite / high-altitude platform / base station can generally cover a large area. Under a given link budget and system resource, a satellite improves the coverage area of a single beam through beam design to improve the overall coverage. However, due to the limited coverage range of a single beam, a single satellite still needs a large number of beams to complete wider coverage.

[0114] Among them, the beam is the main lobe of the directional array diagram of a signal. The coverage range of a beam refers to the projection range of the beam on the ground. The network device can adjust the weight of the antenna so that the beam sent by the network device points to different directions and has different coverage ranges. The coverage range of the beam discussed in this application refers to the coverage range of the beam on the ground. With the movement of the satellite base station and the adjustment of the weight, the coverage range of the beam will also change.

[0115] The NTN communication includes networking by using unmanned aerial vehicles, high-altitude platforms, satellites, and other devices to provide data transmission, voice communication, and other services for terminal devices. The high-altitude platform is generally 8-50 km high from the ground.

[0116] According to the orbital height of the satellite, the satellite communication system can be divided into the following three types: geostationary earth orbit (GEO) satellite communication system (also known as synchronous orbit satellite system), medium earth orbit (MEO) satellite communication system, and low earth orbit (LEO) satellite communication system.

[0117] The GEO satellite is generally also called a geostationary satellite, and the orbital height can be 35786 kilometers (km). The main advantage is that it is relatively stationary relative to the ground and can provide a large coverage area. However, the disadvantages of GEO satellites are also relatively prominent: such as the distance from the earth is too large, requiring a large-diameter antenna; the transmission delay is large, about 0.5 seconds, which cannot meet the needs of real-time services; at the same time, the orbital resources are relatively scarce, the launch cost is high, and it cannot provide coverage for the polar regions.

[0118] The orbit height of MEO satellite is between 2000km and 35786km, and global coverage can be achieved with a relatively small number of satellites. However, the transmission delay is higher than that of LEO satellite, and it is mainly used for positioning and navigation.

[0119] The orbit height of LEO satellite is between 300km and 2000km. Compared with MEO satellite and GEO satellite, LEO satellite has lower orbit height, smaller data propagation delay, less power loss, and relatively lower launch cost. Therefore, LEO satellite communication network has attracted widespread attention in recent years.

[0120] It is generally believed that NTN communication has different channel characteristics compared with terrestrial communication, such as large transmission delay and large Doppler frequency offset. Exemplarily, the round-trip delay of GEO satellite communication is 238-270(ms). The round-trip delay of LEO satellite communication is 8ms-20ms.

[0121] Limited by manufacturing and launch costs, the on-board data processing capability and transmission power are also limited, and the satellite communication network cannot currently provide terminal devices with a communication rate comparable to that of terrestrial communication networks. In order to break through this limitation and improve the overall signal processing capability and communication throughput of the satellite network, satellite operators are preparing to launch a large constellation of low-orbit satellites, that is, to make up for the limitation of the communication capability of a single satellite by increasing the number of satellites. In future NTN communication systems, after a terminal device accesses the system, multiple satellites can cooperate to provide communication services for the same terminal device, which provides a basic condition for multi-satellite cooperative transmission.

[0122] Referring to the architecture diagram of satellite communication shown in FIG. 8. FIG. 8 takes the next generation radio access network (NG-RAN) as an example to introduce the communication architecture between the terminal device (UE in the figure), the NG-RAN, the core network and the data network (DN) in the satellite communication.

[0123] The satellite can provide wireless access services for the terminal device and schedule wireless resources for the terminal device accessing the network through the satellite. The satellite and the terminal device communicate through the air interface (which can be various types of air interfaces, such as 5G air interface). Among them, the satellite and the NTN gateway can communicate through the NG interface, and the satellite can interact with the core network through the NTN gateway to exchange non-access stratum (NAS) signaling of the core network and service data of the user. In the multi-satellite cooperation scenario, the satellite and the satellite can establish an inter-satellite link (ISL) to communicate.

[0124] The coverage of actual ground base stations is limited, and there are many TN and NTN coexistence scenarios. For future NTNs, the target scenarios are mainly to supplement coverage and provide places where TN devices cannot cover. The goal of the first stage is to achieve integrated design of TN and NTN. To achieve integrated design of TN and NTN, one problem that needs to be solved is the coexistence of TN and NTN. The current protocol defines six major scenarios for TN and NTN coexistence, two of which are important scenarios, including: interference of TN devices to terminal devices served by NTN devices, and interference of NTN devices to terminal devices served by TN devices.

[0125] Therefore, embodiments of the present application provide a communication method in which TN devices and NTN devices can interact information for interference avoidance, for example, TN devices send location information of electronic fences to NTN devices, which indicate the area where NTN devices need to perform interference avoidance for terminal devices served by TN devices.

[0126] Firstly, a communication method is introduced below in combination with FIG. 9 to achieve interference avoidance of NTN devices to terminal devices served by TN devices in the scenario of coexistence of NTN and TN.

[0127] FIG. 9 is a schematic flowchart of a communication method 900 provided by embodiments of the present application. The steps of method 900 can be performed by TN devices and NTN devices interacting. Wherein, the TN device is, for example, a network device on the ground or a communication module in the network device, or a circuit or chip responsible for communication function in the network device (such as a modem chip, or a SoC chip or SIP chip containing a modem core); the NTN device is, for example, a satellite or a communication module in the satellite, or a circuit or chip responsible for communication function in the satellite (such as a modem chip, or a SoC chip or SIP chip containing a modem core).

[0128] In the present application, the TN device refers to an access network device deployed on the ground, such as a ground base station. The NTN device refers to a device deployed in the air, such as a satellite.

[0129] Method 900 includes S901 to S904, and optionally, method 900 further includes S905 to S907. Each step is described in detail below.

[0130] S901, the first TN device determines a first area based on a preset condition, the preset condition including at least one of the following: the number of at least one NTN device, the level of the electronic fence, the interference resistance capability of at least one terminal device served by the TN device, or the location information of at least one terminal device served by the TN device.

[0131] In the present application, the electronic fence is used to enclose an area, which can be regarded as a virtual geographical boundary of the area. In the TN and NTN coexistence scenario, the NTN device cannot send beams within the electronic fence of the TN device, and the NTN device can only send beams outside the electronic fence of the TN device.

[0132] The level of the electronic fence can be determined based on the number of the at least one NTN device. For example, the more the number of the at least one NTN device, the higher the level of the electronic fence, and the larger the area enclosed by the electronic fence; the less the number of the at least one NTN device, the lower the level of the electronic fence, and the smaller the area enclosed by the electronic fence.

[0133] The at least one TN device is within the coverage of the at least one NTN device, or the at least one NTN device is within the coverage of the at least one TN device.

[0134] The first TN device is one of the at least one TN device, and is configured to collect information of the electronic fence of the at least one TN device. The first TN device has strong radio frequency capability, and its beam direction can be downward to communicate with a terminal device (which can be referred to as a TN terminal) on the ground, or upward to send beams to the NTN device in the air. The first TN device also has strong processing capability, for example, the first TN device can collect and integrate the information of the electronic fence.

[0135] Exemplarily, the geographical positions of the at least one TN device are adjacent.

[0136] The number of the at least one NTN device can also be described as a constellation scale.

[0137] The at least one NTN device includes a first NTN device, which can communicate with the TN device, and can also collect information of the electronic fence of the TN device. The first NTN device also has a forwarding capability for the information of the electronic fence.

[0138] In a possible implementation, the first TN device determines a first area according to the number of the at least one NTN device. The larger the number of the at least one NTN device, that is, the larger the constellation scale, the larger the determined first area, and vice versa.

[0139] In another possible implementation, the first TN device determines a first area according to position information of a terminal device served by the at least one TN device, and the first area is the coverage area of the at least one TN device.

[0140] The number of the at least one TN device can be one, i.e., the at least one TN device is the first TN device.

[0141] The number of the at least one TN device can be multiple, and the at least one TN device is adjacent in geographical position. The at least one TN device includes the first TN device.

[0142] The first TN device determines the first area based on a preset condition, which can include that the first TN device determines the first area based on position information of terminal devices served by the at least one TN device, or that the first TN device determines the first area based on coverage areas of the at least one TN device. That is, the first area can be a coverage area of the at least one TN device, wherein each TN device in the at least one TN device has its coverage area and terminal devices served in the coverage area. The first area includes at least one terminal device served by the at least one TN device.

[0143] The first TN device can further determine the first area based on interference resistance capability of terminal devices served by the at least one TN device.

[0144] In a possible implementation, the interference resistance capability of terminal devices served by the at least one TN device includes total interference resistance capability of terminal devices served by the at least one TN device.

[0145] Exemplarily, if the total interference resistance capability is weak, the first TN device can determine a larger first area; otherwise, if the total interference resistance capability is strong, the first TN device can determine a smaller first area.

[0146] In another possible implementation, the interference resistance capability of terminal devices served by the at least one TN device includes interference resistance capability of terminal devices served by each TN device in the at least one TN device.

[0147] Exemplarily, when determining the first area, the first TN device can include an area in which terminal devices with weak interference resistance capability are located.

[0148] Optionally, a terminal device can report UE capability to a TN device serving the terminal device to indicate its interference resistance capability. Other TN devices can report interference resistance capability of terminal devices served to the first TN device.

[0149] Optionally, the interference resistance capability of the terminal device served by the at least one TN device comprises the interference resistance capability of the terminal device served by each of the at least one TN device, and the location information of the terminal device served by the at least one TN device comprises the location information of the terminal device served by each of the at least one TN device.

[0150] In a possible implementation, the first TN device determines the first region based on a preset condition, comprising: the first TN device determines a second region of each TN device based on the number of the at least one NTN device, the level of the electronic fence, the interference resistance capability of the terminal device served by each TN device, or the location information of the terminal device served by each TN device; and the first TN device determines the first region based on the second region of each TN device. Specifically, the first TN device can integrate at least one second region corresponding to at least one TN device to obtain the first region.

[0151] For example, if the interference resistance capability of the terminal device served by a TN device is weak, the coverage area of the TN device can be included in the determination of the first region; if the interference resistance capability of the terminal device served by a TN device is strong, the coverage area of the TN device can not be included in the determination of the first region, or the area where the terminal device with weak interference resistance capability served by the TN device is located can be included in the determination of the first region.

[0152] S902, the first TN device determines the location information of the first electronic fence based on the first region. Wherein, the at least one NTN device cannot send beams within the first electronic fence.

[0153] In this application, the first electronic fence is used to enclose the first region, and the first electronic fence can be regarded as a virtual geographical boundary of the first region, for example, the schematic diagram of the first electronic fence shown in FIG. 10. In the TN and NTN coexistence scenario, the NTN device cannot send beams within the electronic fence of the TN, and the NTN device can only send beams outside the first electronic fence of the TN.

[0154] Optionally, the first TN device determines the location information of the first electronic fence based on the first region, which can comprise: the first TN device determines the position of the terminal device after moving outward by a preset distance from the edge of the first region as the location of the first electronic fence.

[0155] The preset distance can be 0, that is, the first TN device determines the position of the terminal device at the edge of the first area as the position of the first electronic fence. Alternatively, the preset distance can be greater than 0, that is, the first TN device can expand the range of the electronic fence, for example, move the terminal device at the edge of the first area outward by X distance units, and the position after the movement is the position of the first electronic fence.

[0156] Alternatively, the first TN device can also determine the position information of the first electronic fence according to the anti-interference capability of the terminal device at the edge of the first area, for example, the terminal devices at the edge of the first area in FIG. 10 include terminal device 1 to terminal device 9, wherein the anti-interference capability of terminal device 9 is weak, and the anti-interference capability of terminal device 2 is strong. Therefore, when determining the boundary of the first area, that is, determining the position information of the first electronic fence, the first TN device can be away from terminal device 9 to avoid the interference of the beam of the NTN device on terminal device 9 as much as possible.

[0157] S903, the first TN device sends the position information of the first electronic fence to the first NTN device. Correspondingly, the first NTN device receives the position information of the first electronic fence.

[0158] The position information of the first electronic fence is used for the first NTN device to avoid interference with the terminal devices served by the TN device. Specifically, the first TN device, or the at least one TN device described above, can send a beam within the first electronic fence, and the first NTN device, or the at least one NTN device described above, cannot send a beam within the first electronic fence.

[0159] Alternatively, the position information of the first electronic fence includes beam position information where the first electronic fence is located.

[0160] It should be understood that the beam position is a piece of geographical area related to the beam, which can be regarded as a piece of area covered by the beam on the ground. The area can be a region on the ground defined in advance, and the device can send a beam towards this region.

[0161] Alternatively, the beam position information includes a single-level beam position index, for example, as shown in FIG. 11A, each beam position corresponds to a single-level index, for example, the index is 0, 1, or 2, etc.

[0162] Optionally, the wave position information includes a multi-level wave position index. That is, each wave position corresponds to an N-level index, and the index of a wave position can be expressed as a first-level wave position index + a second-level wave position index + … + an N-level wave position index, where N is greater than or equal to 2. For example, as shown in FIG. 11B, the index of a wave position includes a first-level wave position index (the wave position index of the largest hexagonal region shown in FIG. 11B), a second-level wave position index (the wave position index of a medium-sized hexagonal region in the largest hexagonal region shown in FIG. 11B), and a third-level wave position index (the wave position index of the smallest hexagonal region in the medium-sized hexagonal region in the largest hexagonal region shown in FIG. 11B).

[0163] Exemplarily, N = 3, and a multi-level wave position index is denoted as A1_B1_C1, where A1 is a first-level wave position, the first-level wave position index is a wave position index at a cell group level, B1 is a second-level wave position index, the second-level wave position index is a wave position index at a cell level, and C1 is a third-level wave position index, the third-level wave position index is a wave position index at a beam level.

[0164] S904, the first NTN device performs interference avoidance on a terminal device served by the TN device based on the position information of the first electronic fence.

[0165] After receiving the information of the first electronic fence, the first NTN device obtains the information of the area in which the transmission beam is prohibited. Then, the first NTN device performs interference avoidance on a terminal device served by the TN device based on the information of the first electronic fence. The interference avoidance performed by the first NTN device on the terminal device served by the TN device includes interference avoidance performed by the first NTN device on at least one terminal device served by the TN device.

[0166] The interference avoidance performed by the first NTN device on the terminal device served by the TN device can include interference avoidance in a quasi earth-fixted scenario and interference avoidance in an earth-moving scenario. The interference avoidance in the two scenarios is described below.

[0167] It should be understood that, in satellite communication, a satellite cell includes a quasi earth-fixted cell (i.e., a quasi earth-fixted scenario) and an earth-moving cell (i.e., an earth-moving scenario).

[0168] The semi-static ground fixed scenario refers to that, in a period of time, the ground coverage area of the service cell of the satellite does not change with the movement of the satellite. That is, the region on the ground is served in a "staring" manner, or in a "staring" mode. Referring to FIG. 12A, at t0, the satellite serves a region on the ground, and with the movement of the satellite, at t1, the satellite serves the same region on the ground. That is, with the movement of the satellite, in a period of time, the satellite adjusts the beam pointing direction and always sends a beam to the same region on the ground. In such a scenario, the beam direction is relatively flexible.

[0169] For this scenario, optionally, the first NTN device performs interference avoidance on the TN based on the information of the first electronic fence, including: the first NTN device adjusts the beam pointing direction to send a beam outside the range of the first electronic fence, or the first NTN device closes a beam that is expected to be sent into the range of the first electronic fence. Wherein, the first NTN device can adjust the beam pointing direction to adjust the beam direction pointing to the inside of the first electronic fence to outside the first electronic fence, so as to avoid sending a beam in the range of the first electronic fence. In this way, the interference of the NTN device on the terminal device served by the TN device can be reduced, so as to protect the communication performance of the terminal device served by the TN device.

[0170] Wherein, the first NTN device closing the beam that is expected to be sent into the range of the first electronic fence can also be alternatively described as: the first NTN device deactivating / deactivating the beam that is expected to be sent into the range of the first electronic fence.

[0171] The ground moving scenario refers to that, the ground coverage area of the service cell of the satellite changes with the movement of the satellite. Referring to FIG. 12B, at t0, the satellite serves a region on the ground, and with the movement of the satellite, at t1, the satellite serves another region on the ground. That is, with the movement of the satellite, the satellite does not adjust the beam, and the beam pointing direction moves with the movement of the satellite.

[0172] For this scenario, optionally, the first NTN device performs interference avoidance on the TN based on the information of the first electronic fence, including: the first NTN device closes a beam that is expected to be sent into the range of the first electronic fence. In this way, the interference of the NTN on the TN can be reduced, so as to protect the communication performance of the TN.

[0173] In the embodiments of the present application, in the TN and NTN coexistence scenario, the first TN device can send the position information of the first electronic fence to the first NTN device, so that the first NTN device can perform interference avoidance on the terminal device served by the TN device in the region surrounded by the first electronic fence, which is beneficial to reduce the interference of the NTN device on the terminal device served by the TN device in the TN and NTN coexistence scenario, and further beneficial to improve the throughput of the terminal device served by the TN device.

[0174] Optionally, the first electronic fence can be an electronic fence of the first TN device.

[0175] Optionally, the first TN device can receive position information of a second electronic fence of each of the at least one TN device, and determine the position information of the first electronic fence based on the position information of the second electronic fence of the at least one TN device.

[0176] For example, as shown in FIG. 13, a schematic diagram of the first TN device collecting position information of an electronic fence, the at least one TN device includes TN device 1, TN device 2, and TN device 3. The first TN device can receive position information of a second electronic fence of TN device 1 (for example, the electronic fence shown by line 2 in FIG. 13), position information of a second electronic fence of TN device 2 (for example, the electronic fence shown by line 3 in FIG. 13), and position information of a second electronic fence of TN device 3 (for example, the electronic fence shown by line 4 in FIG. 13).

[0177] Optionally, the first TN device integrates the position information of the second electronic fence of each of the at least one TN device to determine the position information of the first electronic fence. That is, the first electronic fence can be a global electronic fence.

[0178] Since the second electronic fence sent by each TN device to the first TN device can overlap, for example, as shown in FIG. 13, the first TN device integrates the position information of the electronic fence of the first TN device (for example, shown by line 1 in FIG. 13), the position information of the second electronic fence of TN device 1, the position information of the second electronic fence of TN device 2, and the position information of the second electronic fence of TN device 3 to determine the position information of the first electronic fence, which can form an electronic fence as shown by line 1, line 2, line 3, and line 4 in FIG. 13.

[0179] Optionally, the first TN device integrating the position information of the second electronic fence of the at least one TN device can include splicing and cropping the position information of the second electronic fence of the at least one TN device to complete the integration of the information, as shown in FIG. 14.

[0180] Optionally, after receiving the position information of the first electronic fence, the first TN device can send the position information of the cropped electronic fence of the first electronic fence to other TN devices on demand, which is referred to as a third electronic fence in the present application.

[0181] Optionally, the first NTN device clips the first electronic fence based on the ephemeris information of the at least one NTN device to obtain a third electronic fence corresponding to each NTN device in the at least one NTN device, and the third electronic fence corresponding to each NTN device is a region in which the terminal device served by the TN device needs to avoid interference of the each NTN device.

[0182] In a possible implementation, the first NTN device calculates the first electronic fence and the coverage expected by each NTN device according to the ephemeris information of each NTN device, so as to obtain the position information of the third electronic fence of each NTN device. In other words, the first NTN device determines the overlapping part of the region surrounded by the first electronic fence and the coverage expected by the NTN device based on the ephemeris information of each NTN device, and obtains the position information of the third electronic fence of each NTN device from the position information of the first electronic fence according to the overlapping part, see FIG. 15.

[0183] It should be understood that if there is no overlapping part between the coverage expected by a certain NTN device and the region surrounded by the first electronic fence, that is, the NTN device will not cause interference to the terminal device served by the TN device, the NTN device does not need to avoid interference to the terminal device served by the TN device, and the first NTN device can not send the position information of the electronic fence to the NTN device.

[0184] Optionally, the first NTN device sends the position information of the third electronic fence corresponding to each NTN device in the at least one NTN device to the each NTN device.

[0185] In the embodiments of the present application, the first TN device interacts with the first NTN device to obtain the position information of the electronic fence, and then the first NTN device sends the position information of the third electronic fence to other NTN devices on demand, which is beneficial to avoid interaction between the first TN device and multiple NTN devices, and is beneficial to reduce the number of link switching caused by high-speed movement of the NTN device.

[0186] In the above method 900, the first TN device sends the position information of the first electronic fence to the first NTN device, and the first NTN device performs interference avoidance for the terminal device served by the TN device based on the information of the first electronic fence. Another communication method is introduced below in combination with FIG. 16 to realize interference avoidance of the TN device for the terminal device served by the NTN device in the TN and NTN coexistence scenario.

[0187] FIG. 16 is a schematic flowchart of another communication method 1600 provided by the embodiments of the present application. The steps of the method 1600 can be performed by a TN device interacting with an NTN device. The TN device is, for example, a network device on the ground or a communication module in the network device, or a circuit or chip responsible for communication functions in the network device (such as a modem chip or a SoC chip or a SIP chip containing a modem core). The NTN device is, for example, a satellite or a communication module in the satellite, or a circuit or chip responsible for communication functions in the satellite (such as a modem chip or a SoC chip or a SIP chip containing a modem core).

[0188] The method 1600 includes S1601 to S1603, which are described in detail below.

[0189] S1601, a first NTN device acquires second information, the second information including position information of a terminal device served by at least one NTN device, or including information of a coverage area of the at least one NTN device.

[0190] The at least one NTN device includes the first NTN device, and the coverage area of the at least one NTN device is within the coverage area of the at least one TN device, or the coverage area of the at least one TN device is within the coverage area of the at least one NTN device. The at least one TN device includes the first TN device.

[0191] More details of the first NTN device and the first TN device can be found in the description above, which will not be repeated here.

[0192] In a possible implementation, the second information includes the position information of the terminal device served by the at least one NTN device. This mode is suitable for a scenario where terminal devices within the coverage area of the at least one NTN device are relatively dispersed, such as personal outdoor activities.

[0193] Optionally, the position information of the terminal device can include global coordinate system (GCS) coordinates of the terminal device, or earth-centered, earth-fixed (ECEF) coordinates of the terminal device.

[0194] In another possible implementation, the second information includes the information of the coverage area of the at least one NTN device. This mode is suitable for a scenario where terminal devices within the coverage area of the at least one NTN device are relatively concentrated.

[0195] Optionally, the information of the coverage area of the at least one NTN device comprises: a single-level beam index of the coverage area of the at least one NTN device, or a multi-level beam index of the coverage area of the at least one NTN device. The single-level beam index and the multi-level beam index are described above and will not be repeated here.

[0196] The wave position index, the geographic area index, the index of the nested geographic area, the electronic fence, etc. can be used for indication.

[0197] Optionally, the wave position index can be a single-level beam index, or a multi-level wave position index. The multi-level wave position index can also be referred to as a nested wave position index.

[0198] S1602, the first NTN device sends second information to the first TN device, and correspondingly, the first TN device receives the second information.

[0199] The second information is used for interference avoidance of the terminal device served by the at least one NTN device, in other words, the second information can be regarded as information for interference avoidance / coordination.

[0200] S1603, the first TN device performs interference avoidance of the terminal device served by the at least one NTN device based on the second information.

[0201] After receiving the second information, the first TN device can perform user scheduling based on the location information of the terminal device served by the at least one NTN device, or the information of the coverage area of the at least one NTN device.

[0202] For example, as shown in FIG. 17, when the first NTN device performs user scheduling, it first performs scheduling of a timing bitmap and scheduling of beam priority, wherein the scheduling of the timing bitmap refers to scheduling of available time domain resources, and the scheduling of the beam priority refers to scheduling of available beams, i.e., selecting time domain resources and beam resources first. In this application, when the first TN device performs beam priority scheduling, the second information is used as the input of the scheduler, so that the available beam resources can be scheduled, for example, beams outside the coverage area of the at least one NTN device are scheduled, in other words, beams inside the coverage area of the at least one NTN device are not scheduled. After the beam priority scheduling, the first TN device performs user scheduling based on the scheduled beams, without the need to match the beams again.

[0203] In the embodiments of the present application, in the TN and NTN coexistence scenario, the first NTN device can receive the position information of the first electronic fence from the first TN device, so that the first NTN device can perform interference avoidance on the terminal device served by the TN device in the area surrounded by the first electronic fence, which is beneficial to reduce the interference of the NTN device on the terminal device served by the TN device in the TN and NTN coexistence scenario, and further improve the throughput of the terminal device served by the TN device.

[0204] The embodiments of the present application also provide a method for adaptively setting the level of the electronic fence, in which the first NTN device or the first TN device can determine different levels of the electronic fence based on different satellite scales.

[0205] For example, for a larger satellite scale, in order to avoid the larger interference of the larger satellite scale on the TN terminal, the range of the electronic fence can be expanded, so as to affect the TN network.

[0206] In a possible implementation, the level of the electronic fence can be determined by the TN network, see the method 1800 below.

[0207] FIG. 18 is a schematic flowchart of a method 1800 for adaptively setting the level of the electronic fence according to an embodiment of the present application. The method 1800 includes S1801 to S1807, and each step is described in detail below.

[0208] S1801, the first NTN device sends a constellation scale to the first TN device. Correspondingly, the first TN device receives the constellation scale.

[0209] The constellation scale can be the number of at least one NTN device, and the coverage area of the at least one NTN device is in the service area of the first TN device, or the coverage area of the first TN device is in the coverage area of the at least one NTN device.

[0210] S1802, the first TN device determines the level of the electronic fence based on the constellation scale.

[0211] FIG. 19 is a schematic diagram of an adaptive electronic fence. As shown in FIG. 19, the electronic fence 2 is an electronic fence expanded on the basis of the electronic fence 1. The electronic fence 1 has a lower level and a smaller surrounded area, and the electronic fence 2 has a higher level and a larger surrounded area.

[0212] For example, the larger the constellation scale, the higher the level of the electronic fence, and the larger the surrounded area; on the contrary, the smaller the constellation scale, the lower the level of the electronic fence, and the smaller the surrounded area.

[0213] Exemplarily, the electronic fence 1 is a region where the interference intensity of the NTN to the TN is X, and the electronic fence 2 is a region where the interference intensity of the NTN to the TN is Y, where Y is greater than X.

[0214] It should be understood that the values of X and Y can be predefined by a protocol or indicated by a network side, and embodiments of the present application do not limit this.

[0215] S1803, the first TN device sends the level of the electronic fence to at least one TN device, and correspondingly, the at least one TN device receives the level of the electronic fence.

[0216] S1804, each TN device in the at least one TN device determines the location information of the electronic fence corresponding to the level of the electronic fence based on the level of the electronic fence.

[0217] For example, level 0 is the lowest level, and level 1 is a higher level than level 0. The electronic fence corresponding to level 0 encloses a smaller area, i.e., the TN device determines a smaller area, and determines the location information of the electronic fence based on the smaller area. The electronic fence corresponding to level 1 encloses a larger area, i.e., the TN device determines a larger area, and determines the location information of the electronic fence based on the larger area.

[0218] S1805, each TN device in the at least one TN device sends the location information of the electronic fence corresponding to the level of the electronic fence to the first TN device. Correspondingly, the first TN device receives the location information of the electronic fence corresponding to the level of the electronic fence sent by each TN device.

[0219] S1806, the first TN device integrates the location information of the electronic fence from the at least one TN device to obtain global location information of the electronic fence.

[0220] The integration of the location information of the electronic fence corresponding to the level of the electronic fence sent by the at least one TN device can include splicing and cropping the location information of the electronic fence corresponding to the level of the electronic fence sent by the at least one TN device, for example, as shown in FIG. 14, which will not be described here.

[0221] S1807, the first TN device sends the global location information of the electronic fence to the first NTN device. Correspondingly, the first NTN device receives the global location information of the electronic fence.

[0222] In the embodiment of the present application, the first TN device can adaptively adjust the level of the electronic fence according to the constellation scale, and send the level of the electronic fence to other TN devices. Other TN devices can determine the size of the electronic fence according to the level of the electronic fence. In this way, dynamic interference control can be achieved, which is conducive to reducing the impact of NTN on TN in a large-scale constellation.

[0223] In another possible implementation, the level of the electronic fence can be determined by the NTN network, see method 2000 below.

[0224] FIG. 20 is a schematic flowchart of another method 2000 for adaptively adjusting the level of the electronic fence according to an embodiment of the present application. The method 2000 includes S2001 and S2002, and S1803 to S1807 described above.

[0225] S2001, the first NTN device determines the level of the electronic fence based on the constellation scale.

[0226] For the determination of the level of the electronic fence, see the description of S1802 above, which will not be repeated here.

[0227] S2002, the first NTN device sends the level of the electronic fence to the first TN device. Correspondingly, the first TN device receives the level of the electronic fence.

[0228] For the description of S1803 to S1807, see the description above, which will not be repeated here.

[0229] In the embodiment of the present application, the first NTN device can adaptively adjust the level of the electronic fence according to the constellation scale, and send the level of the electronic fence to the first TN device. Then, the first TN device sends the level of the electronic fence to other TN devices. Other TN devices can determine the size of the electronic fence according to the level of the electronic fence. In this way, dynamic interference control can be achieved, which is conducive to reducing the impact of NTN on TN in a large-scale constellation.

[0230] It should be understood that the interference of NTN on TN is related to not only the constellation scale, but also the transmission power of the NTN device. Therefore, the satellite scale in the above method 1800 or method 2000 can be replaced by the transmission power of the NTN device, that is, the first TN device can receive the transmission power of the NTN device, and determine the level of the electronic fence according to the transmission power of the NTN device.

[0231] For example, the transmission power of the NTN device includes: the transmission power of the first NTN device, or the average transmission power of multiple NTN devices (including the first NTN device), or the maximum transmission power of multiple NTN devices (including the first NTN device).

[0232] Exemplarily, the greater the transmission power of the NTN device, the greater the interference, and then a higher level of the electronic fence needs to be determined, and the range of the electronic fence needs to be expanded.

[0233] It should also be understood that the TN terminal can determine the interference level of the NTN device to itself by measuring the reference signal. For example, the NTN device sends reference information, such as channel state information-reference signal (CSI-RS), synchronization signal block (SSB), etc., to the TN terminal, the TN terminal measures the reference signal to obtain a measurement quantity, and determines the interference level of the NTN device to itself based on the measurement quantity. The measurement quantity is, for example, reference signal receiving power (RSRP), received signal strength indication (RSSI), signal to noise ratio (SNR), reference signal receiving quality (RSRQ), etc. When the interference level is greater than a threshold, the TN terminal can send interference information to the TN device serving it, and the TN device serving it can determine the level of the electronic fence based on the interference information after receiving the interference information.

[0234] It should also be understood that the TN device can determine the interference level of the NTN device to itself by measuring the reference signal. For example, the NTN device sends reference information, such as CSI-RS, SSB, etc., to the TN device, the TN device measures the reference signal to obtain a measurement quantity, and determines the interference level of the NTN device to itself based on the measurement quantity. The measurement quantity is, for example, RSRP, RSSI, SNR, RSRQ, etc. When the interference level is greater than a threshold, the TN device can determine the level of the electronic fence based on the interference level.

[0235] It should be understood that the above method of adaptively determining the level of the electronic fence can be applied to the above method 900. For example, the method 900 further includes S905: the first NTN device sends first information to the first TN device, the first information being used to indicate the level of the electronic fence, or the first information being used to indicate the number of at least one NTN device. Correspondingly, the first TN device receives the first information. Wherein, S905 can be performed before S901.

[0236] Optionally, the method 900 further includes S906: determining, by the first TN device, the level of the electronic fence based on the first information. If the first information indicates the level of the electronic fence, the first TN device can directly determine the level of the electronic fence. If the first information indicates the number of the at least one NTN device, the first TN device determines the level of the electronic fence based on the number of the at least one NTN device. For example, the more the number of the at least one NTN device, the higher the level of the electronic fence; the less the number of the at least one NTN device, the lower the level of the electronic fence, and vice versa. Wherein, S906 can be executed after S905.

[0237] Optionally, the method 900 further includes S907: sending, by the first TN device, the level of the electronic fence to the at least one TN device, the level of the electronic fence being used for each TN device of the at least one TN device to determine the size of a second electronic fence of each TN device. The introduction of the second electronic fence can be referred to the description in the above, which will not be described here. Wherein, S907 can be executed after S906.
