[0036] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0038] The following detailed description of this exemplary implementation method is provided in conjunction with the accompanying drawings and embodiments.

[0039] First, this disclosure provides a method for selecting antennas for an air-to-ground communication network, which can be executed by any electronic device with computing capabilities.

[0040] Figure 1 This invention discloses a flowchart of an antenna selection method for an air-to-ground communication network according to an embodiment of the present invention. Figure 1 As shown, the method for selecting an antenna for an air-to-ground communication network provided in this embodiment includes the following steps:

[0041] S102, identify the uplink co-channel interference pattern of multiple antennas of the ATG airborne terminal to the terrestrial IMT network.

[0042] The uplink co-channel interference pattern represents the intensity of uplink co-channel interference experienced by a ground-based IMT network from an ATG airborne terminal at a specific time or location.

[0043] Although the uplink of the terrestrial IMT network is subject to interference from the uplink of the co-frequency ATG network, the intensity of co-frequency interference between the terrestrial IMT base station and the ATG airborne terminal is related to the consistency between the incident angle of the uplink signal of the ATG airborne terminal and the pointing direction of the side lobes on the antenna of the terrestrial IMT base station. That is, the intensity of co-frequency interference between the terrestrial IMT base station and the ATG airborne terminal is greatest when the incident angle of the uplink signal of the ATG airborne terminal coincides with the pointing direction of the side lobes on the antenna of the terrestrial IMT base station.

[0044] Figure 2 This diagram illustrates co-channel interference between an ATG airborne terminal at different locations and an IMT cell with different antenna downtilt angles, as shown in an embodiment of this disclosure. Figure 2 As shown, for the first ATG airborne terminal 201 and the second ATG airborne terminal 202 at different locations, the downlink interference intensity of the first ground co-frequency IMT base station 203 and the second ground co-frequency IMT base station 204 to the first ATG airborne terminal 201 and the second ATG airborne terminal 202 is different; the uplink interference intensity of the first ATG airborne terminal 201 and the second ATG airborne terminal 202 to the first ground co-frequency IMT base station 203 and the second ground co-frequency IMT base station 204 is different.

[0045] Figure 3 The diagram shows the measured results of the co-channel interference intensity of an ATG base station terminal on a terrestrial IMT network in an embodiment of this disclosure. Through on-site testing, analysis and verification, as the ATG airborne terminal gradually approaches the terrestrial IMT cell, the co-channel interference experienced by the terrestrial IMT cell gradually increases from the normal level to the peak value; then, as the ATG airborne terminal gradually moves away from the terrestrial IMT cell, the co-channel interference experienced by the terrestrial IMT cell gradually decreases from the peak value back to the normal level.

[0046] Furthermore, the duration of the strongest co-channel interference between the ATG airborne terminal and the ground-based IMT base station is very short, only 1 to 2 seconds; this indicates that the time it takes for the uplink signal incident angle of the ATG airborne terminal to align with the strongest pointing direction of the sidelobe on the antenna of the ground-based IMT base station is very short.

[0047] like Figure 3 As shown, the horizontal axis represents time, and the vertical axis represents the average RB noise floor. The period from 15:00:42 to 15:02:13 represents the co-channel interference generated by the airborne ATG terminal to the ground IMT cell. The maximum duration of the interference intensity is 2 seconds, and the interference intensity goes through a process of first increasing and then decreasing.

[0048] Based on the above characteristics of co-channel interference, the uplink co-channel interference of the ATG airborne terminal to the ground IMT cell can be reduced by selecting airborne ATG terminal antennas installed at different locations on the aircraft fuselage so that the incident angle of the uplink signal of the ATG airborne terminal avoids the direction of the sidelobe pointing on the ground co-channel IMT base station antenna.

[0049] In one embodiment, based on aircraft route information, IMT data, and ATG data, the uplink co-channel interference pattern of multiple antennas of the ATG airborne terminal to the ground IMT network is calculated.

[0050] In one embodiment, based on historical aircraft flight data, the uplink co-channel interference pattern of multiple antennas of the ATG airborne terminal to the ground IMT network is obtained, that is, the uplink co-channel interference pattern of multiple antennas of the ATG airborne terminal to the ground IMT network is obtained based on measurements taken during a certain aircraft flight.

[0051] S104. Based on the uplink co-channel interference pattern, determine the target antenna corresponding to the ATG airborne terminal. The target antenna is an antenna with low co-channel interference to the ground IMT network.

[0052] In one embodiment, when the uplink co-channel interference pattern is the uplink co-channel interference intensity of multiple antennas of the ATG airborne terminal in the time dimension of the terrestrial IMT cell, the target antennas corresponding to the ATG airborne terminal at different times are determined according to the uplink co-channel interference pattern.

[0053] In one embodiment, time can be absolute time or relative time, etc.; relative time includes, but is not limited to: relative time relative to the time when the aircraft takes off, relative time relative to the time when the aircraft lands, etc.

[0054] In one embodiment, when the uplink co-channel interference pattern is the uplink co-channel interference intensity of a ground IMT cell in the location dimension caused by multiple antennas of an ATG airborne terminal, the target antennas corresponding to the ATG airborne terminal at different locations are determined based on the uplink co-channel interference pattern.

[0055] In one embodiment, the location includes, but is not limited to, specific location, relative location, etc. The location can be the specific location of the ATG airborne terminal on the flight path, or the specific location of the ATG airborne terminal projected onto the ground, etc., and the comparison is not limited.

[0056] In one embodiment, the target antenna can be selected by combining the interference patterns of the location dimension and the time dimension. For example, the uplink co-channel interference intensity A of the first antenna of the ATG airborne terminal in the terrestrial IMT cell in the location dimension can be obtained, and the uplink co-channel interference intensity B of the first antenna of the ATG airborne terminal in the time dimension can be obtained. The uplink co-channel interference intensity A and the uplink co-channel interference intensity B can be weighted and summed to determine the final uplink co-channel interference intensity. The final uplink co-channel interference intensity of multiple antennas can be compared, and the antenna with the minimum final uplink co-channel interference intensity can be selected at the corresponding time and location.

[0057] In the above embodiments, the co-channel interference pattern of multiple antennas of the ATG airborne terminal to the uplink of the terrestrial IMT network is identified, and antennas that can avoid the sidelobe pointing of the terrestrial IMT network antennas and have less co-channel interference to the terrestrial IMT network are selected, thereby reducing the co-channel interference of the ATG airborne terminal to the uplink of the IMT network and ensuring the performance of IMT network services.

[0058] Figure 4 This diagram illustrates the flight time and position of an ATG airborne terminal antenna 1 according to an embodiment of the present disclosure. Figure 5 This diagram illustrates the uplink co-channel interference pattern of an ATG airborne terminal antenna 1 based on time and location in an embodiment of this disclosure. The diagram represents the uplink co-channel interference intensity of the ATG airborne terminal 401 antenna 1 on the ground IMT network 402 corresponding to time T0 to time T6 and location L0 to location L6.

[0059] Figure 6 This diagram illustrates the flight time and position of an ATG airborne terminal antenna 2 according to an embodiment of the present disclosure. Figure 7 This illustration shows a time- and location-based uplink co-channel interference pattern of an ATG airborne terminal antenna 2 in an embodiment of this disclosure. The pattern represents the uplink co-channel interference intensity of the ATG airborne terminal antenna 2 on the ground IMT network 602 corresponding to time T0 to time T6 and location L0 to location L6.

[0060] In one embodiment, based on the time-dimensional interference pattern, the antenna with the least co-channel interference to the uplink of the terrestrial IMT cell is selected at a specific time. For example, based on the time-dimensional interference patterns of antenna 1 and antenna 2, antenna 1 is selected at times T0, T1, and T2; and antenna 2 is selected at times T3, T4, T5, and T6.

[0061] In one embodiment, based on the location-dimensional interference pattern, the antenna with the least co-channel interference to the uplink of the ground IMT cell is selected at a specific flight location; for example, based on the location-dimensional interference patterns of antenna 1 and antenna 2, antenna 1 is selected at locations L0, L1 and L2; and antenna 2 is selected at locations L3, L4, L5 and L6.

[0062] Figure 8 This diagram illustrates an ATG airborne terminal antenna selection method according to an embodiment of the present disclosure. Figure 9 This illustration shows a time- and location-based interference pattern after antenna selection for an ATG airborne terminal in an embodiment of this disclosure. The pattern represents the uplink co-channel interference intensity of the antenna 2 of the ATG airborne terminal 801 on the terrestrial IMT network 802 corresponding to time T0 to time T6 and location L0 to location L6.

[0063] In the above embodiments, for the scenario where the uplink of the ATG network and the IMT network are deployed on the same frequency, based on the characteristics of the co-frequency interference of the ATG airborne terminal to the uplink of the terrestrial IMT network, the co-frequency interference patterns of multiple antennas of the ATG airborne terminal to the terrestrial IMT cell are identified, and antenna selection is performed based on time or location. The antenna that can avoid the sidelobe pointing on the antenna of the terrestrial IMT cell, that is, the antenna with less co-frequency interference to the terrestrial IMT cell, is selected, thereby reducing the co-frequency interference of the ATG airborne terminal to the uplink of the IMT network.

[0064] Figure 10 This diagram illustrates a flowchart of a method for determining uplink co-channel interference patterns according to an embodiment of this disclosure. Figure 10 As shown, the uplink co-channel interference pattern determination method provided in this embodiment includes the following steps:

[0065] S1002, Obtain aircraft route information.

[0066] In one embodiment, the aircraft route information includes, but is not limited to, flight time, flight latitude and longitude, flight altitude, and flight speed.

[0067] S1004, Based on the aircraft flight path information, determine the ground IMT cell and the corresponding IMT data.

[0068] In one embodiment, an aircraft projection route is obtained based on aircraft route information; a ground IMT cell and its corresponding IMT data are determined based on the aircraft projection route; the aircraft route information is projected onto the ground to obtain the aircraft projection route; and ground IMT cells located at a certain distance on both sides of the aforementioned aircraft projection route are obtained, wherein the ground IMT cells are severely interfered cells.

[0069] In one embodiment, the distance values ​​on both sides of the flight path can be set automatically based on historical data, or the distance values ​​on both sides of the flight path can be set manually.

[0070] In one embodiment, IMT data includes, but is not limited to, at least one of the following: terrestrial IMT cell base station data, terrestrial IMT cell antenna pattern data, etc.

[0071] In one embodiment, the terrestrial IMT cell base station data includes, but is not limited to: base station latitude and longitude, antenna azimuth angle, antenna downtilt angle, antenna height, base station altitude, and other data.

[0072] The base station's latitude and longitude are the latitude and longitude corresponding to the location of the IMT cell base station; the antenna azimuth angle can be the angle between the antenna's horizontal plane normal direction and the due north direction; the antenna downtilt angle is the angle between the antenna's vertical plane normal direction and the ground; the antenna mounting height is the height from the ground to the middle of the antenna.

[0073] In one embodiment, the ground IMT cell antenna pattern data includes, but is not limited to, antenna horizontal plane and antenna vertical plane pattern data.

[0074] S1006, Obtain ATG data from the ATG airborne terminal.

[0075] In one embodiment, ATG data includes at least one of the following: ATG antenna pattern data and ATG antenna installation data, etc.

[0077] In one embodiment, the ATG antenna installation data includes, but is not limited to: ATG installation location, distance between ATG antennas, and tilt angle of the ATG antenna normal relative to the ground.

[0078] S1008. Based on aircraft route information, IMT data, and ATG data, the uplink co-channel interference pattern of multiple antennas of the ATG airborne terminal to the ground IMT network is obtained.

[0079] In the above embodiments, based on the aircraft route information, IMT data, and ATG data, the co-channel interference pattern of multiple antennas of the ATG airborne terminal to the uplink of the ground IMT network is obtained. By identifying the co-channel interference pattern of multiple antennas of the ATG airborne terminal to the ground IMT cell, the antenna that can avoid the sidelobe pointing of the ground IMT cell antenna is selected, that is, the antenna with less co-channel interference to the ground IMT cell is selected, thereby reducing the co-channel interference of the ATG airborne terminal to the IMT network uplink.

[0080] Based on the same inventive concept, this disclosure also provides an antenna selection device for an air-to-ground communication network, as shown in the following embodiment. Since the principle by which this device embodiment solves the problem is similar to that of the above-described method embodiment, the implementation of this device embodiment can refer to the implementation of the above-described method embodiment, and repeated details will not be elaborated further.

[0081] Figure 11 This diagram illustrates an antenna selection device for an air-to-ground communication network according to an embodiment of the present disclosure. Figure 11 As shown, the air-to-ground communication network antenna selection device 11 includes: an identification module 1101 and a determination module 1102;

[0082] The identification module 1101 identifies the co-channel interference pattern of multiple antennas of the ATG airborne terminal of the ground-to-air communication network to the uplink of the IMT ground-based international mobile communication network.

[0083] In one embodiment, the identification module 1101 includes an airborne ATG terminal flight information acquisition module, used to acquire ATG terminal flight information, including terminal location, flight altitude, flight speed, flight route and other information.

[0084] In one embodiment, the identification module 1101 includes: an airborne ATG terminal antenna information acquisition module, used to acquire ATG antenna pattern data corresponding to multiple antennas of the ATG airborne terminal, including ATG horizontal plane and ATG vertical plane pattern data, etc.

[0085] The airborne ATG terminal antenna information acquisition module is also used to acquire ATG antenna installation data corresponding to multiple antennas of the ATG airborne terminal, including ATG installation location, distance between ATG antennas, and tilt angle of the ATG antenna normal relative to the ground.

[0086] In one embodiment, the identification module 1101 includes: a ground IMT cell base station information acquisition module, used to acquire ground co-frequency IMT cell base station information, including base station location information, antenna azimuth angle, antenna downtilt angle, ground IMT cell antenna pattern information, etc.

[0087] In one embodiment, the identification module 1101 includes a co-channel interference pattern identification module, used to identify the co-channel interference pattern of the ATG airborne terminal to the uplink of the ground IMT cell based on the ATG terminal flight information, ATG antenna pattern data and ATG antenna installation data, and ground co-channel IMT cell base station information.

[0088] In one embodiment, the identification module 1101 includes: a ground IMT cell determination module, used to acquire aircraft flight path information; obtain an aircraft projection flight path based on the aircraft flight path information; determine ground IMT cells and IMT data corresponding to the ground IMT cells based on the aircraft projection flight path; project the aircraft flight path information onto the ground to obtain the aircraft projection flight path; and acquire ground IMT cells located at a certain distance on both sides of the aforementioned aircraft projection flight path, wherein the ground IMT cells are severely interfered cells.

[0089] The determination module 1102 determines the target antenna corresponding to the ATG airborne terminal based on the uplink co-channel interference pattern. The target antenna is an antenna with low co-channel interference to the ground IMT network.

[0090] In one embodiment, the determining module 1102 includes: a first determining module, which determines the target antennas corresponding to the ATG airborne terminal at different times based on the uplink co-channel interference pattern when the uplink co-channel interference pattern is the uplink co-channel interference intensity of the ground IMT cell in the time dimension caused by multiple antennas of the ATG airborne terminal.

[0091] In one embodiment, the determining module 1102 includes: a second determining module, which determines the target antennas corresponding to the ATG airborne terminal at different locations based on the uplink co-channel interference pattern when the uplink co-channel interference pattern is the uplink co-channel interference intensity of the ground IMT cell in the location dimension caused by multiple antennas of the ATG airborne terminal.

[0092] In one embodiment, the determining module 1102 includes: a third determining module, which can select a target antenna by comprehensively considering the interference patterns in the location dimension and the time dimension. For example, it can obtain the uplink co-channel interference intensity A of the first antenna of the ATG airborne terminal in the location dimension of the ground IMT cell, and obtain the uplink co-channel interference intensity B of the first antenna of the ATG airborne terminal in the time dimension of the ground IMT cell. It can perform a weighted summation of the uplink co-channel interference intensity A and the uplink co-channel interference intensity B to determine the final uplink co-channel interference intensity, compare the final uplink co-channel interference intensity of multiple antennas, and select the antenna with the minimum final uplink co-channel interference intensity at the corresponding time and location.

[0093] The above embodiments are applied to scenarios where ATG networks and IMT networks are deployed on the same frequency, especially in scenarios where there is uplink co-channel interference between ATG networks and IMT networks. By identifying the co-channel interference patterns of multiple antennas of the ATG airborne terminal to the ground IMT cell, antenna selection is performed based on time or location. The selected antennas can avoid the sidelobe pointing of the antennas of the ground IMT cell, that is, the antennas with less co-channel interference to the ground IMT cell are selected. This helps to reduce the interference of the ATG network to the uplink of the ground IMT network, enhance the availability of the co-channel ATG network, and save spectrum resources.

[0094] Figure 12 A schematic diagram of an exemplary system architecture for an antenna selection method or device for an air-to-ground communication network that can be applied to embodiments of this disclosure is shown.

After receiving the radio signals transmitted by the ATG base station 1203, the airborne ATG terminal 1202 converts them into WiFi signals for use by the terminal equipment 1205 in the cabin of the aircraft 1201. When the airborne ATG terminal 1202 transmits radio signals to the ATG base station 1203, it will interfere with the ground IMT base station 1204.

[0096] The airborne ATG terminal 1202 and the ATG base station 1203, as well as the airborne ATG terminal 1202 and the terminal device 1205, are all connected via a network, which can be a wired network or a wireless network.

Depending on the terminal platform, the specific form of the application client may also differ; for example, the application client may be a mobile client, a PC client, etc.
