Abstract
Description
Technical Field
[0001] This application relates to the field of satellite-to-ground frequency sharing technology, and in particular to a method and apparatus for determining interference levels. Background Technology
[0002] Currently, satellite communication networks and terrestrial networks generally adopt a frequency-separated construction approach to avoid inter-system interference risks and reduce deployment difficulty. However, low-frequency bands below 6 GHz (Gigahertz), suitable for direct mobile phone connections, are resource-scarce and have low spectrum utilization, making it difficult to allocate independently usable frequency bands for low-Earth orbit satellite networks. Satellite-ground frequency sharing is a potential solution, but severe co-channel interference between satellites and ground stations must be avoided.
[0003] Existing solutions consider equipping satellites with a noise floor monitoring module to acquire uplink interference levels during transit using methods such as beam scanning, beam staring, and beam skipping. However, due to variations in satellite position and antenna pointing angle corresponding to different interference data, the acquired uplink interference levels exhibit numerous variables. In beam scanning mode, the satellite position continuously changes while the beam pointing angle remains constant, resulting in inconsistencies in the three major influencing parameters for different beams at the same time. In beam staring / beam skipping mode, the satellite position changes, and the beam pointing angle adjusts accordingly, leading to inconsistencies in the three major influencing parameters for the same beam at different times. Furthermore, while normal beam scanning acquires interference data, even with a constant beam pointing angle and only one beam, eliminating the need for data normalization, this method relies on only one beam and is limited by the satellite's trajectory, potentially failing to obtain comprehensive data.
[0004] Therefore, it is of great significance to normalize the uplink interference data acquired from different locations and pointing angles in order to accurately assess the interference situation in satellite-to-ground frequency sharing scenarios. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] To facilitate a full understanding of the technical solution of this application, the following content is hereby introduced: Due to variations in satellite position and antenna pointing angle, and with insufficient data samples, the acquired noise floor data exhibits significant uncertainty, making it difficult to directly use for interference assessment. For example... Figure 1 As shown, the interference directional to position a is NI1 at time t0. At this point, NI1 < NI threshold, but this does not mean that the interference directional to position a at any time and location is less than the NI threshold. Therefore, whether the interference at the satellite's service position a is controllable remains unknown. Furthermore, to guide subsequent commercial deployment, the noise floor monitoring results can be output as a geographic area interference heatmap to visually demonstrate the interference from the ground network to the satellite. However, due to inconsistent values of influencing parameters in the existing data and the lack of normalization, the interference intensity is difficult to interpret and analyze uniformly. Simultaneously, differences exist between different satellite systems in parameters such as orbital altitude and antenna gain, making the interference data obtained from the test unsuitable for direct application to other satellite systems. Therefore, it is necessary to normalize the noise floor data obtained from the uplink interference test.
[0028] Figure 2 This is one of the flowcharts illustrating the interference level determination method provided in this application, such as... Figure 2 As shown, the method may include the following steps: Step 210: Obtain the uplink interference value of the network device; Step 220: Determine the transmission loss, antenna gain, and the coverage area corresponding to the antenna gain; Step 230: Determine the ground transmitter interference value for each frequency band based on the uplink interference value, transmission loss, antenna gain, and coverage area corresponding to the antenna gain of the network device. Among them, antenna gain includes the average gain of the main lobe of the beam and any item in the antenna pattern; The coverage area corresponding to antenna gain includes either the beam coverage area or the coverage area of different antenna gain levels.
[0029] It should be noted that the execution subject of the above interference level determination method can be a computing power unit, such as any computing power unit deployed in a terrestrial NTN (Non-Terrestrial Network) base station, wireless network management, gateway station, telemetry and control station, or satellite-ground cooperation unit, or a computing power unit set up independently of the above-mentioned equipment. This application does not make specific limitations in this regard.
[0030] It is understandable that a computing unit possesses at least one of the following capabilities: 1. Ephemeris information can be obtained directly or indirectly from satellite platforms / satellite operators.
[0031] 2. Antenna pattern information / key data information for antenna gain simulation can be obtained directly or indirectly from satellite manufacturers, such as the number of elements, element spacing, element pattern, etc.
[0032] 3. The mapping relationship between wave number and latitude / longitude coordinates can be obtained directly or indirectly from the satellite operator.
[0033] 4. It can determine uplink interference based on input parameters and output the geographic area and interference heatmap.
[0034] 5. Based on the interference value at any angle the satellite points, suggestions for the formulation of wavelet planning maps and wavelet frequency mapping tables can be provided directly or indirectly to the NTN base station.
[0035] Specifically, network devices have the ability to detect uplink interference values, such as satellites and NTN base stations; this application does not specifically limit this.
[0036] Antenna gain is used to characterize the receiving capability of a network device's receiving antenna at different pointing angles.
[0037] The average gain of the main lobe of a beam is used to characterize the average receiving capability of a network device's receiving antenna within the main lobe direction.
[0038] Uplink interference refers to the level of interference caused to network equipment by the ground transmitter during uplink transmission.
[0039] Transmission loss refers to the total loss experienced by the uplink interference value during its transmission from the ground transmitter to the network equipment.
[0040] Antenna radiation patterns are used to represent the gain distribution of an antenna at different azimuth angles.
[0041] Specifically, in step 210, the computing unit obtains the uplink interference value of the satellite coverage. Generally, the uplink interference value can be expressed by the following formula: (1) in, This refers to the overall interference effect within the beam range of the satellite.
[0042] If it is necessary to decouple the uplink interference value from information such as satellite position and beam pointing, then formula (1) needs to be reversed, and the reversed formula is expressed as: (2) In step 220, the computing unit determines the transmission loss, antenna gain, and the coverage area corresponding to the antenna gain.
[0043] In step 230, the computing unit determines the interference value of each wave position at the ground transmitter based on the uplink interference value, transmission loss, antenna gain, and the coverage area corresponding to the antenna gain.
[0044] Antenna gain may include any of the following: Optionally, the antenna gain can be the average gain of the main lobe of the beam. In practical operational scenarios, the interference signals received by the satellite typically include ground network interference within the main lobe range, and may also include interference signals received through each side lobe. Since the antenna gain in the side lobe direction is usually at least 10 dB lower than that in the main lobe direction, and side lobes have strong suppression capabilities and their coverage is difficult to model accurately, the interference contribution of side lobes is not dominant. In scenarios with limited computing resources, the side lobe gain can be ignored, and the accuracy and computational efficiency of the interference calculation results can be guaranteed by using only the relevant parameters of the main lobe.
[0045] Alternatively, antenna gain can also be the antenna pattern. Based on the antenna pattern, the antenna gain can be divided into multiple gain levels, each representing a specific gain range and corresponding to a specific spatial coverage area. In scenarios supported by high computing resources, using different antenna gain levels can achieve more accurate determination of interference levels.
[0046] The above methods can be chosen according to the specific needs of the scenario. The antenna gain obtained by any method can be used to determine the interference value of the ground transmitter at each subsequent wave position.
[0047] The coverage area corresponding to the antenna gain can include any of the following: Optionally, when the antenna gain is the average gain of the main lobe of the beam, the coverage area corresponding to the antenna gain can be the beam coverage area.
[0048] Alternatively, when the antenna gain is the antenna pattern, the coverage area corresponding to the antenna gain can be the coverage area of different antenna gain levels.
[0049] The above methods can be chosen according to the specific scenario requirements. The coverage area corresponding to the antenna gain obtained by any method can be used to determine the ground transmitter interference value for each subsequent waveband.
[0050] Furthermore, after obtaining the ground-based transmitter interference values for each wave position, the computing unit can further generate a geographic area interference heatmap with wave position as the granularity.
[0051] The interference level determination method provided in this application determines the ground-based transmitter interference value for each frequency band by using the uplink interference value, transmission loss, antenna gain, and the coverage area corresponding to the antenna gain of the network device. The antenna gain includes the average gain of the main lobe of the beam and any item in the antenna pattern; the coverage area corresponding to the antenna gain includes the beam coverage area and any item of the coverage area at different antenna gain levels. This process can effectively reconstruct the ground-based transmitter interference value for each frequency band by using different forms of antenna gain parameters. Therefore, this method can solve the problem of difficulty in normalizing uplink interference data acquired at different locations and pointing angles in existing technologies, and achieve accurate assessment of interference in satellite-ground frequency sharing scenarios.
[0052] In one embodiment, when the antenna gain includes the average gain of the main lobe of the beam and the coverage area corresponding to the antenna gain includes the beam coverage area, determining the ground transmitter interference value for each wave position may include: The ground-based transmitter interference value for each wavelength is determined based on the uplink interference value, transmission loss, average gain of the main lobe of the beam, beam area, and wavelength area.
[0053] Specifically, beam area refers to the effective coverage area formed by the main lobe of the receiving antenna beam at the current pointing angle on the Earth's surface.
[0054] Wavefront area refers to the smallest coverage unit area formed on the ground when the receiving beam is pointed to a specific wavefront.
[0055] Optionally, when the antenna gain includes the average gain of the main lobe of the beam and the coverage area corresponding to the antenna gain includes the beam coverage area, the gain from the beam sidelobe direction can be ignored in the process of determining the ground transmitter interference value for each beam position. It can be expressed by the following formula: (3) in, This refers to the interference effect in the direction of the main lobe within the sub-satellite beam range.
[0056] Furthermore, since the wavefront is the smallest interference assessment unit within the satellite coverage area, based on formulas (2) and (3), in order to obtain interference assessment results at the wavefront granularity, the following formula can be further refined: (4) The interference level determination method provided in this application determines the ground-based transmitter interference value for each wavelength by using the uplink interference value, transmission loss, average gain of the main lobe of the beam, beam area, and wavelength area. This method, while ignoring the influence of sidelobe gain, significantly simplifies the interference level determination process and improves the efficiency and engineering applicability of interference level determination.
[0057] In one embodiment, the method may further include: Based on the location and beam position of the network device, determine the off-axis angle and azimuth angle of the receiving beam of the network device, and determine the beam center antenna gain based on the off-axis angle and azimuth angle. The average gain of the beam center antenna and the beam edge antenna is taken as the average gain of the main lobe of the beam.
[0058] Specifically, the off-axis angle is used to indicate the angle between the main axis direction of the satellite receiving antenna beam and the beam position direction. For example, when the main axis of the satellite antenna points to the reference direction, if the beam position direction is not in the reference direction, a certain angle is formed, which is the off-axis angle.
[0059] Azimuth is used to indicate the angle of rotation of the wavefront direction relative to the true north direction of the satellite platform in the horizontal plane. For example, starting from true north, the angle between the wavefront direction and north is measured clockwise, and the resulting angle is the azimuth.
[0060] The beam center antenna gain can be obtained by looking up the off-axis angle and azimuth angle in the antenna radiation table. This antenna radiation table can be constructed based on the array pattern, using the off-axis angle and azimuth angle as indices to record the theoretical gain values of the satellite receiving antenna in different spatial directions.
[0061] The gain of a beam edge antenna refers to the antenna gain in the direction corresponding to the boundary of the main lobe range of the satellite receiving antenna. It can be found in the antenna radiation table or estimated based on the main lobe information. This application does not make any specific limitation on this.
[0062] Optionally, the computing unit calculates the off-axis angle and azimuth angle of the satellite's receiving beam pointing towards the beam position based on the satellite's current orbital position and the latitude and longitude coordinates of the beam position on the ground. Based on this angle combination, it then obtains the beam center antenna gain for the corresponding beam position from the antenna pattern lookup table. Simultaneously, the computing unit can also obtain the antenna gain at the beam edge direction from the antenna pattern lookup table.
[0063] Since formula (3) is used to count the ground transmitter interference level of cellular terminals / base stations under the coverage of the main lobe of the beam, in order to more accurately characterize the overall receiving capability of the main lobe, the computing unit can use the average value of the beam center antenna gain and the beam edge antenna gain as the average gain of the main lobe of the beam.
[0064] The interference level determination method provided in this application determines the off-axis angle and azimuth angle of the received beam of the network device based on the network device's location and beam position. Then, it determines the beam center antenna gain based on the off-axis angle and azimuth angle, and finally uses the average of the beam center antenna gain and the beam edge antenna gain as the average gain of the beam main lobe. This method effectively reduces the computational complexity of the average beam main lobe gain, thereby improving overall computational efficiency while maintaining accuracy.
[0065] In one embodiment, the method may further include: The beam area is determined based on the off-axis angle and azimuth angle of the receiving beam of the network device, the orbital height of the network device, and the half-power beamwidth of the normal beam. The beam position area represents the beam coverage area pointed towards the nadir point.
[0066] Understandably, the half-power beamwidth of the normal beam, also known as the half-power beamwidth or 3dB beamwidth, is a key parameter describing the main lobe beamwidth of the antenna pattern.
[0067] Specifically, the computing unit can calculate the coverage area formed by the beam on the Earth's surface at the current pointing angle, i.e., the beam area, based on the off-axis angle and azimuth angle of the satellite receiving beam, the satellite orbital altitude, and the half-power beamwidth of the normal beam.
[0068] The beam area is used to characterize the actual receiving capability and interference range under the beam direction. In practical calculations, to improve accuracy, beam area calculations should also consider three key influencing factors: first, the beam broadening effect at larger off-axis angles, leading to increased coverage; second, the beam coverage amplification effect caused by changes in satellite-to-ground distance; and third, the Earth's curvature, which also amplifies the beam area. These three factors together determine the true value of the beam area under the pointing angle.
[0069] Furthermore, the beam coverage area pointed to the sub-satellite point is the beam position area.
[0070] The interference level determination method provided in this application determines the beam area by using the off-axis angle and azimuth angle of the received beam from the network device, the orbital height of the network device, and the half-power beamwidth of the normal beam. The coverage area when the beam points towards the nadir point is used as the beam area. This method can determine the beam area based on the actual coverage of the beam, thereby improving the accuracy of interference level determination.
[0071] In one embodiment, when the antenna gain includes the antenna pattern and the coverage area corresponding to the antenna gain includes the coverage area of different antenna gain levels, determining the ground transmitter interference value for each waveband includes: Based on antenna testing and antenna gain simulation, the ground projection area of each antenna gain level and the dominant antenna gain level is determined; the dominant antenna gain level is the antenna gain level in which the corresponding area ratio exceeds the preset area ratio threshold. Based on the uplink interference value, transmission loss, each antenna gain level, and the ground projection area of the dominant antenna gain level, determine the ground transmitter interference value per unit area. The ground-based transmitter interference value for each waveband is determined based on the ground-based transmitter interference value per unit area and the waveband area.
[0072] Specifically, antenna gain levels are different gain ranges defined based on antenna testing and antenna gain simulation, with each level corresponding to a specific directional gain. For example, gains above 30dB are considered high-gain levels, gains between 20dB and 30dB are considered medium-gain levels, and gains below 20dB are considered low-gain levels. This application does not impose specific limitations on these levels.
[0073] Antenna testing can be achieved through field experiments, where the gain of the antenna in different directions is measured to obtain actual data.
[0074] Antenna gain simulation can be performed by using 3D electromagnetic simulation software to build an antenna structure model and calculate the theoretical directional gain, which can be used to help classify gain levels.
[0075] The preset area percentage threshold can be a fixed value, such as 60%, 70% or 80%; or it can be dynamically configured according to the beam coverage characteristics and interference level accuracy requirements. This application does not make specific limitations on this.
[0076] Specifically, to obtain more accurate interference data, the computing unit also considers ground network interference received by each sidelobe of the satellite. First, based on antenna testing and antenna gain simulation, the computing unit combines the actual gain values of the antenna in each direction with the theoretically simulated gain values to classify the antenna gain levels. The antenna gain simulation can be based on 3D electromagnetic simulation software to obtain the directional gain distribution at different pointing angles, thereby significantly reducing the cost of manual modeling and computation while ensuring accuracy.
[0077] Secondly, the computing unit determines the area ratio corresponding to each antenna gain level. If the area ratio corresponding to a certain antenna gain level exceeds a preset area ratio threshold, then it is designated as the dominant antenna gain level.
[0078] Then, the computing unit determines the ground-based transmitter interference value per unit area based on the uplink interference value, transmission loss, antenna gain levels, and the ground projection area of the dominant antenna gain level. Ignoring differences in terrestrial network deployment across different regions, the uplink interference value can be expressed by the following formula: (5) Where N represents the total number of antenna gain levels, and n represents the dominant antenna gain level.
[0079] Furthermore, based on the known uplink interference value, antenna gain level, transmission loss, waveband area, and ground transmitter interference value per unit area, and in conjunction with formula (5), the ground transmitter interference value for each waveband can be expressed by the following formula: (6) Finally, after acquiring the ground-based transmitter interference values for each band, the computing unit decouples the interference source data from information such as satellite position and beam pointing. This allows for the generation of a geographic area interference heatmap at the band level. Based on this band-level interference heatmap, the computing unit can calculate the interference level when a satellite points at any angle from any location. This process can guide band planning within the satellite service area and the configuration of band frequency mapping tables, determining whether target bands should be reused at the same frequency or allocated with adjacent frequencies to reduce interference and improve spectrum utilization efficiency.
[0080] The interference level determination method provided in this application determines the ground-projected area of each antenna gain level and the dominant antenna gain level through antenna testing and antenna gain simulation. Based on this, the ground-based transmitter interference value per unit area is determined according to the uplink interference value, transmission loss, each antenna gain level, and the ground-based projected area of the dominant antenna gain level. Finally, the ground-based transmitter interference value for each waveband is determined based on the ground-based transmitter interference value per unit area and the waveband area. This method can fully consider the ground network interference received by each sidelobe of the network device, obtain more comprehensive data through antenna simulation, avoid misjudgments caused by ignoring directional differences, and significantly improve the accuracy of interference level determination.
[0081] In one embodiment, based on antenna testing and antenna gain simulation, the ground projection area of each antenna gain level and the dominant antenna gain level is determined, including: Based on antenna testing and antenna gain simulation, determine the antenna gain diagram of the receiving antenna of the network device at various angles; Based on the antenna gain diagrams from various angles, determine the gain levels of each antenna and the dominant antenna gain level. The ground projection area of the dominant antenna gain level is determined based on the gain range of the dominant antenna gain level.
[0082] Specifically, firstly, the computing unit constructs antenna gain maps of the satellite receiving antenna under different directions based on antenna testing and antenna gain simulation results. These antenna gain maps characterize the receiving capability at different pointing angles, providing a basis for classifying gain levels.
[0083] Subsequently, the computing unit divides the antenna gain map into multiple antenna gain levels according to the directional gain value based on the preset gain range, with each gain level corresponding to a specific angular range. Further, the computing unit determines the dominant antenna gain level from among these gain levels.
[0084] Finally, the computing unit determines the ground projection area of the dominant antenna gain level based on the gain range of the dominant antenna gain level.
[0085] The interference level determination method provided in this application obtains the gain distribution of the receiving antennas of the network device in all directions through antenna testing and antenna gain simulation, thereby determining the gain levels of each antenna and the dominant antenna gain level, and further determining the ground projection area of the dominant antenna gain level. This method can avoid interference level errors caused by unreasonable gain level division, helps to accurately obtain the ground projection area of the dominant antenna gain level, and thus improves the reliability of subsequent interference level calculations.
[0086] In one embodiment, obtaining the uplink interference value of the network device includes: The uplink noise floor monitoring module obtains the uplink interference value of the network device. Specifically, the uplink noise floor monitoring module is used for: Monitor the uplink interference values of network devices and transmit the uplink interference values to the ground via power supply or telemetry and control links.
[0087] Specifically, the uplink noise floor monitoring module can be deployed at a satellite / NTN base station or at a ground control center; this application does not make any specific restrictions on this.
[0088] The uplink noise floor monitoring module can monitor the uplink interference value of network devices by means of beam skipping, beam scanning, or beam staring. This application does not make any specific limitation on this.
[0089] Uplink interference values may include absolute time, beam position information, frequency resource information, and interference values. For example, beam position information may include beam position number, latitude and longitude, beam azimuth angle, and beam elevation angle. Frequency resource information may include RB (Resource Block) number, bandwidth range, frequency interval, etc., which are not specifically limited in this application.
[0090] Specifically, the uplink noise floor monitoring module is mounted on a satellite or NTN base station and monitors the uplink interference value per second for each position using a beam-hopping method. During the beam-hopping pattern development phase, the uplink noise floor monitoring module designs the beam-hopping interval and sequence based on the total number of serving positions. That is, the beam-hopping must uniformly jump between positions according to a predetermined interval and sequence, ensuring that all positions acquire interference data evenly within the same observation period, thereby avoiding inconsistencies in the timing of interference data.
[0091] For example, the uplink noise floor monitoring module can be set to serve 500 wavelengths, and the hopping beams need to jump evenly within 1 second, so each wavelength serves 2 time slots; it can also be set to serve 1000 wavelengths, so each wavelength serves 1 time slot.
[0092] During the transition process, uplink noise floor monitoring records the uplink interference value per second for each wave position, including absolute time, wave position information, frequency resource information, and interference value. Furthermore, the aforementioned uplink interference value can be transmitted to the ground in real time via the power supply link or telemetry and control link.
[0093] Subsequently, after receiving the uplink interference value, the computing unit can calculate the interference power level experienced by the serving frequency band under the absolute time and RB number. This calculation result can serve as the basic data for determining the interference level, providing accurate support for subsequent frequency band planning and frequency reuse strategy formulation.
[0094] The interference level determination method provided in this application monitors the uplink interference value at each wavelength using an uplink noise floor monitoring module in a beam-hopping manner, and transmits it to the ground via a feeder link or telemetry and control link. This method enables uniform and continuous uplink interference value acquisition, ensuring temporal consistency and spatial coverage integrity of the uplink interference values at each wavelength, thus providing accurate input data for subsequent interference level determination.
[0095] In one embodiment, determining the transmission loss includes: Based on ephemeris information, determine the location of the network device at absolute time, and based on the location of the network device at absolute time and its wave position, determine the satellite-to-ground distance; Determine the path loss based on the distance between the satellite and the ground; Based on path loss, obtain transmission loss.
[0096] It is understood that transmission loss in actual transmission scenarios may include scintillation loss as well as atmospheric attenuation, and this application does not specifically limit it.
[0097] Specifically, ephemeris information refers to the sequence data of satellite position and orbital parameters at different times. It can be obtained through GNSS (Global Navigation Satellite System) systems or through real-time updates by ground telemetry and control systems. This application does not make specific limitations on it.
[0098] The three-dimensional straight-line distance between the satellite and the ground network equipment.
[0099] For example, the computing unit first determines the satellite's position at an absolute time based on ephemeris data. Then, it combines this with the wave position to determine the satellite-to-ground distance.
[0100] Secondly, the computing unit calculates the path loss based on the obtained satellite-to-ground distance. The path loss can be expressed by the following formula: Path loss = 32.45 + 20 × log (satellite-to-ground distance) + 20 × log (frequency) (7) Among them, 32.45 is a unit conversion constant used to unify the units of satellite-to-ground distance and frequency in the formula.
[0101] Furthermore, in order to more accurately reflect transmission loss, the computing unit can also superimpose other losses such as scintillation loss and atmospheric attenuation, for example, scintillation loss is taken as 0.3dB and atmospheric attenuation as 0.1dB empirical values.
[0102] Furthermore, the transmission loss can be dynamically calibrated using on-orbit measured data to adapt to loss fluctuations in actual communication environments, thereby improving the accuracy and robustness of interference level determination.
[0103] The interference level determination method provided in this application determines the location of network devices at absolute time using ephemeris information and combines this with the wavefront position to determine the satellite-to-ground distance. Based on this, path loss is calculated using the satellite-to-ground distance, and transmission loss is obtained by considering factors such as scintillation loss and atmospheric attenuation. This method can fully consider multiple sources of loss, effectively improving the accuracy and reliability of transmission loss calculation, thus providing crucial support for high-precision interference level determination.
[0104] In one embodiment, the method may further include: The first interference estimate for the network equipment is determined based on the ground-based transmitter interference value, transmission loss, average gain of the main lobe of the beam, beam area, and beam area for each wavelength.
[0105] Understandably, in scenarios where satellites are in constant motion, physical parameters such as the distance between the satellite and the waveband, and the pointing angle, will dynamically change, causing corresponding changes in transmission loss, beam area, and waveband area. Therefore, when the satellite's orbital position changes, these parameters need to be updated in real time, and combined with the ground transmitter interference values for each waveband, the interference level caused by the ground transmitter to network equipment during uplink transmission needs to be re-estimated, i.e., the first interference estimate.
[0106] Specifically, firstly, the computing unit determines the satellite's trajectory based on ephemeris information and selects several sample points on the orbit as the satellite's position.
[0107] Subsequently, the computing unit, combined with the position of the target beam position, obtains the off-axis angle, azimuth angle, and satellite-to-ground distance of the satellite receiving antenna. Based on this, it obtains the transmission loss, average gain of the main lobe, beam area, and beam position area.
[0108] Finally, the computing unit calculates the first interference estimate at the current satellite pointing angle based on the ground-based transmitter interference value, transmission loss, average gain of the main lobe of the beam, beam area, and beam area for each wave position. The first interference estimate is expressed by the following formula: (8) The interference level determination method provided in this application determines the first interference estimate of network equipment by using the ground-based transmitter interference value, transmission loss, average gain of the main lobe of the beam, beam area, and beam area for each wavelength position. Based on the known ground-based transmitter interference values for each wavelength position and combined with the average gain of the main lobe of the beam, this method can quickly calculate the first interference estimate, making it suitable for interference level calculation scenarios with high real-time requirements.
[0109] In one embodiment, the method may further include: The second interference estimate for network equipment is determined based on the ground-based transmitter interference value, transmission loss, antenna gain level, and the ground-projected area of the dominant antenna gain level for each wavelength.
[0110] Understandably, in scenarios where satellites are constantly in motion, the spatial coverage, transmission loss, and the ground projection area of the dominant antenna gain level will all adjust accordingly. Therefore, when the satellite's orbital position changes, these parameters need to be updated in real time, and combined with the ground-based transmission interference values for each frequency band, the interference level caused by the ground transmitter to network equipment during uplink transmission needs to be re-estimated, i.e., the second interference estimate.
[0111] Specifically, firstly, the computing unit determines the ground projection area of each antenna gain level and the dominant antenna gain level based on antenna testing and antenna gain simulation.
[0112] Next, based on the ground-based transmitter interference values for each wavelength, the ground-based transmitter interference value per unit area is calculated. The ground-based transmitter interference value per unit area can be expressed by the following formula: (9) Finally, the computing unit combines transmission loss, antenna gain levels, and the ground projection area of the dominant antenna gain level to determine the second interference estimate for the network device. The second interference estimate is expressed by the following formula: (10) The interference level determination method provided in this application determines the second interference estimate of network equipment by using the ground-based transmitter interference value at each frequency, transmission loss, antenna gain level, and the ground-projected area of the dominant antenna gain level. This method can more accurately reflect the impact of ground-based transmitter interference values at each frequency on the interference level, thereby achieving higher precision calculation of the second interference estimate, and is suitable for scenarios with high requirements for interference assessment accuracy.
[0113] To facilitate a clearer understanding of the technical solutions in the various embodiments of this application, this application provides... Figure 3 Please provide an explanation.
[0114] Specifically, in satellite-to-ground frequency sharing scenarios, the uplink noise floor monitoring module is mounted on a satellite or NTN base station, monitoring the uplink interference value per second for each frequency band using a beam-hopping method. During the beam-hopping pattern development phase, the uplink noise floor monitoring module designs the beam-hopping interval and sequence based on the total number of serving frequency bands. That is, the beam-hopping must hop evenly between frequency bands according to a predetermined interval and sequence. Furthermore, the aforementioned uplink interference values can be transmitted to the ground in real time via a feeder link or a telemetry and control link.
[0115] On one hand, after receiving the uplink interference value, the computing unit manually configures or obtains interference source data, ephemeris information, antenna gain information, and wave position to latitude and longitude coordinate mapping information from the satellite / ground receiving equipment, and determines the ground transmitter interference value for each wave position based on the above information. The ground transmitter interference value for each wave position can be obtained through any of the following methods: Optionally, when the antenna gain includes the average gain of the main lobe of the beam and the coverage area corresponding to the antenna gain includes the beam coverage area, the gain from the sidelobe direction can be ignored in the process of determining the ground transmitter interference value of each wave position.
[0116] The computing unit determines the ground transmitter interference value for each wave position based on the uplink interference value, transmission loss, average gain of the main lobe of the beam, beam area, and wave position area.
[0117] Optionally, when the antenna gain includes the antenna pattern and the coverage area corresponding to the antenna gain includes the coverage area of different antenna gain levels, the computing unit divides each antenna gain level based on antenna testing and antenna gain simulation, combined with the actual gain value of the antenna in each direction and the theoretical simulation gain value.
[0118] Secondly, the computing unit determines the area ratio corresponding to each antenna gain level. If the area ratio corresponding to a certain antenna gain level exceeds a preset area ratio threshold, then it is designated as the dominant antenna gain level.
[0119] Then, the computing unit determines the ground transmitter interference value per unit area based on the uplink interference value, transmission loss, gain levels of each antenna, and the ground projection area of the dominant antenna gain level.
[0120] Furthermore, based on the ground-based transmitter interference value per unit area and the ground-projected area of the dominant antenna gain level, the ground-based transmitter interference value for each wavelength is determined.
[0121] You can choose any of the above methods depending on the specific needs of the scenario.
[0122] On the other hand, the computing unit can be manually configured or obtain interference source data, ephemeris information, antenna gain information, and wavefront-latitude / longitude coordinate mapping information from the satellite / ground receiving equipment, and determine the interference estimate based on the above information. The interference estimate can be obtained through any of the following methods: Optionally, the computing unit determines the satellite's trajectory based on ephemeris information and selects several sample points on the orbit as the satellite's position.
[0123] Subsequently, the computing unit, combined with the position of the target beam position, obtains the off-axis angle, azimuth angle, and satellite-to-ground distance of the satellite receiving antenna. Based on this, it obtains the transmission loss, average gain of the main lobe, beam area, and beam position area.
[0124] Finally, the computing unit calculates the first interference estimate at the current satellite pointing angle based on the ground transmitter interference value, transmission loss, average gain of the main lobe of the beam, beam area, and beam area for each wave position.
[0125] Optionally, the computing unit determines the ground projection area of each antenna gain level and the dominant antenna gain level based on antenna testing and antenna gain simulation.
[0126] Next, based on the ground-based transmitter interference values for each wave position, the ground-based transmitter interference value per unit area is calculated.
[0127] Finally, the computing unit combines transmission loss, the gain levels of each antenna, and the ground projection area of the dominant antenna gain level to determine the second interference estimate of the network device.
[0128] You can choose any of the above methods depending on the specific needs of the scenario.
