All contents of this invention patent are incorporated herein in their entirety. Technical Field

[0003] The present disclosure relates to the field of mobile communication technology, and in particular to a power control method, device and system, storage medium and electronic equipment. Background Art

[0004] With the rapid development of mobile communications technology, mobile phones and mobile broadband services have become a widespread part of our lives. Given the growing demand for mobile phone use anytime, anywhere, the demand for mobile broadband services is also increasing. In some regions, the use of personal communication devices on aircraft is prohibited due to concerns about electromagnetic compatibility of onboard electronic equipment and flight safety. However, with the rapid development of electronic technology, through continuous research and testing, some regions have now allowed individual users to use personal electronic devices to experience mobile broadband services while in flight.

[0005] The Air to Ground (ATG) network is one of the network solutions for providing personal mobile broadband services within aircraft. ATG airborne terminals communicate with ATG base stations deployed on the ground to provide mobile broadband services to individual passengers in the cabin.

[0006] Most of the time, the ATG base station is only connected to one ATG airborne terminal. The ATG base station terminal can choose a larger transmission power without worrying about the impact on other ATG airborne terminals, thereby achieving better service performance.

[0007] When an ATG network is co-frequency networked with a terrestrial International Mobile Telecommunications (IMT) network, the intensity of co-frequency interference from ATG airborne terminals to the IMT base stations in the terrestrial co-frequency IMT network is related to the number of ATG airborne terminals served by multiple ATG base stations within the same airspace. When multiple ATG airborne terminals, each connected to multiple ATG base stations, exist within the same airspace, the ground interference signals from these multiple ATG airborne terminals on the same frequency band are superimposed, resulting in increased uplink co-frequency interference to the terrestrial IMT network on the same frequency band.

[0008] The existing ATG network uplink power control method is similar to the traditional IMT network uplink power control method. The transmission power of the ATG airborne terminal is controlled by the ATG base station to which it is connected. When the ATG network uplink and the terrestrial IMT network uplink are networked on the same frequency, especially when there are multiple ATG airborne terminals connected to multiple ATG base stations in the same airspace, due to the lack of unified control, the ground interference signals of these multiple ATG airborne terminals on the same frequency band are superimposed, resulting in increased uplink co-frequency interference suffered by the terrestrial IMT network on the same frequency band, affecting the performance of the terrestrial IMT network.

[0009] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0053] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0054] FIG1 shows a schematic diagram of the architecture of a power control system that can be applied in an embodiment of the present disclosure. As shown in FIG1 , the power control system includes: a first network 101, a second network 103, and a plurality of terminals 103; the first network 101 and the second network 102 are networked in the same frequency uplink, and the plurality of terminals 103 are respectively connected to the first network 101 and the second network 102 in communication; the terminal 103 is connected to the first network 101 in communication via a communication link 105, and the terminal 103 is connected to the second network in communication via a communication link 106; the plurality of terminals 103 are all configured with flight information; the second network 102 is used The uplink co-channel interference strength threshold is determined and sent to the first network through the communication link 104; the first network 101 is used to obtain the flight information of the terminal 103 through the communication link 105, and determine the multiple terminals 103 in the same airspace based on the flight information of the multiple terminals 103; based on the uplink co-channel interference strength threshold of the second network 102, the transmission power of the multiple terminals 103 in the same airspace is controlled so that the uplink co-channel interference generated by the superposition of the transmission power of the multiple terminals 103 in the same airspace does not exceed the uplink co-channel interference strength threshold of the second network 102.

[0055] Those skilled in the art will appreciate that the number of the first network, the second network, and the plurality of terminals in FIG1 is merely illustrative, and any number of terminal devices, networks, and servers may be provided based on actual needs, which is not limited in the present disclosure.

[0056] ATG networks are typically deployed on a specific spectrum, operating at a different frequency and transmitting in a different band than the IMT networks used by terrestrial public users. This frequency separation eliminates co-channel interference between ATG and IMT networks. However, with spectrum resources becoming increasingly scarce, some regions lack sufficient bandwidth for ATG networks. This hinders their development and limits the demand for mobile broadband services within aircraft.

[0057] To promote the development of ATG networks and provide users with a better mobile broadband experience on aircraft, research is underway into co-frequency deployment of ATG networks with terrestrial IMT networks. This co-frequency ATG network research project was approved in 3GPP Release 18, with participation from several companies. Key research topics include analyzing the coexistence requirements for co-frequency deployment of ATG networks with IMT networks.

[0058] When the ATG network uplink is deployed on the same frequency as the terrestrial IMT network uplink, the ATG airborne terminal will cause uplink interference to a large area of ​​cells in the terrestrial IMT network. Therefore, the prerequisite for the co-frequency deployment of the ATG network and the IMT network is to reduce the co-frequency interference between the ATG network and the terrestrial IMT network.

[0059] Figure 2 shows how an ATG network's uplink signal interferes with the uplink of an IMT network deployed on the same frequency. An IMT network includes multiple IMT base stations, and IMT terminals can connect to multiple IMT base stations simultaneously. Unlike an IMT network, an ATG base station in an IMT network is connected to a single ATG airborne terminal most of the time.

[0060] Figure 3 shows a schematic diagram of uplink interference from multiple ATG airborne terminals in the same airspace to a co-frequency terrestrial IMT network. The ATG network includes ATG base station 1 and ATG base station 2, the IMT network includes an IMT base station, and the terminals include ATG airborne terminal 1 and ATG airborne terminal 2. ATG airborne terminal 1 is at altitude 1, and ATG airborne terminal 2 is at altitude 2. When the ATG network and the IMT network are co-frequency networked, ATG airborne terminal 1 is connected to ATG base station 1, and ATG airborne terminal 2 is connected to ATG base station 2. The ground signals of ATG airborne terminal 1 and ATG airborne terminal 2 on the same frequency band are superimposed, which will increase the co-frequency interference to the terrestrial IMT base station on the same frequency band.

[0061] Since the power of the ATG airborne terminal is controlled by the ATG base station, when there are multiple ATG airborne terminals connected to multiple ATG base stations in the same airspace, due to the lack of unified control, a single ATG airborne terminal can only achieve power control of the ATG base station to which it is connected, resulting in the uplink co-channel interference generated by the superposition of multiple ATG airborne terminals exceeding the maximum uplink co-channel interference intensity threshold that the IMT network can withstand, causing the IMT network performance to be affected.

[0062] In order to solve the problem that uplink interference in the same frequency group network cannot be uniformly managed and controlled, under the above system architecture, a power control method is provided in an embodiment of the present disclosure, which can be executed by any electronic device with computing and processing capabilities.

[0063] In some embodiments, the power control method provided in the embodiments of the present disclosure can be executed by the first network of the above-mentioned system architecture; in other embodiments, the power control method provided in the embodiments of the present disclosure can be executed by the second network in the above-mentioned system architecture; in other embodiments, the power control method provided in the embodiments of the present disclosure can be implemented by the first network and the second network in the above-mentioned system architecture through interaction.

[0064] FIG4 shows a schematic diagram of a power control method in an embodiment of the present disclosure. As shown in FIG4 , the power control method provided in an embodiment of the present disclosure is applied to a first network, wherein the first network and the second network are networked in the same frequency uplink, and multiple terminals are respectively connected to the first network and the second network for communication, wherein the first network may be an airborne mobile ground-to-air communication ATG network, the second network may be an international mobile communication IMT network, and the terminal may be an ATG airborne terminal. The method includes the following steps:

[0065] Step 402: Obtain flight information of the multiple terminals;

[0066] Step 404: Determine multiple terminals in the same airspace based on the flight information of the multiple terminals;

[0067] Step 406: Based on the uplink co-channel interference strength threshold of the second network, control the transmission power of the multiple terminals in the same airspace so that the uplink co-channel interference generated by the superposition of the transmission power of the multiple terminals in the same airspace does not exceed the uplink co-channel interference strength threshold of the second network.

[0068] When the ATG network and the IMT network are networked at the same frequency and the uplink is deployed at the same frequency, and there are multiple ATG recording terminals in the same airspace that are separately connected to multiple ATG base stations, in order to control co-channel interference, the multiple terminals in the same airspace are first determined through the flight information of the ATG airborne terminal, and then the uplink co-channel interference intensity threshold of the IMT network is used as a restriction condition to jointly adjust the transmission power of the multiple terminals in the same airspace, so that the uplink co-channel interference generated by the superposition of the transmission power of the multiple terminals in the same airspace does not exceed the uplink co-channel interference intensity threshold of the IMT network, and the co-channel interference of the ground interference signals of multiple terminals in the same airspace on the uplink in the same frequency band of the IMT network is reduced, thereby solving the problem of increased co-channel interference of the IMT network due to the superposition of the transmission power of multiple terminals in the same frequency band.

[0069] Regarding the acquisition of flight information of the multiple terminals in step 402, in an embodiment, an ATG airborne terminal generates flight information while in flight, and the flight information of the ATG airborne terminal can be acquired via a communication link connected to the ATG network. The flight information may include: signal strength of an ATG base station of the ATG network connected to the ATG airborne terminal, signal strength of neighboring base stations of the connected ATG base station, location information, altitude information, speed information, route information, and various other types of information.

[0070] As shown in FIG5 , in the embodiment, the first network includes multiple first network base stations that are communicatively connected to the multiple terminals; a single terminal is communicatively connected to a single first network base station at the same time;

[0071] Determining the multiple terminals in the same airspace based on the flight information of the multiple terminals in step 404 may include:

[0072] Step 502: Determine the first network base station proximity determination result based on the flight information of the multiple terminals;

[0073] Step 504: Determine distance determination results of the multiple terminals based on the flight information of the multiple terminals;

[0074] Step 506: Determine multiple terminals in the same airspace based on the first network base station proximity determination result and the distance determination results of the multiple terminals.

[0075] Since a single ATG terminal is connected to a single ATG base station for communication at the same time, when determining whether multiple terminals are in the same airspace, judgment is made from two aspects. On the one hand, the above-mentioned ATG network base station proximity judgment results are judged based on the flight information of multiple ATG airborne terminals. On the other hand, the distance judgment results of multiple ATG airborne terminals are judged based on the flight information of multiple ATG airborne terminals. Finally, the multiple ATG airborne terminals in the same airspace are determined based on the ATG network base station proximity judgment results and the distance judgment results of multiple ATG airborne terminals.

[0076] As shown in FIG6 , in an embodiment, determining the first network base station proximity determination result based on the flight information of the multiple terminals in step 502 may include:

[0077] Step 602: Determine, based on the flight information of the multiple terminals, the signal strength of a first network base station connected to each terminal for communication and the signal strength of a base station adjacent to the connected first network base station;

[0078] Step 604: Obtain geographic location information of a first network base station that is in communication with each terminal;

[0079] Step 606: Determine the neighbor judgment result of the first network base station based on the signal strength of the first network base station connected to each terminal for communication and the signal strength of the adjacent base station of the connected first network base station, as well as the geographic location information of the first network base station connected to each terminal for communication.

[0080] The specific process of step 606 may include:

[0081] The signal strength of the first network base station connected to each terminal for communication is subtracted from the signal strength of the adjacent base station of the connected first network base station to determine the signal strength difference of each terminal; if the signal strength differences of the multiple terminals are equal, and the geographical distances in the geographical location information of the first network base stations corresponding to the multiple terminals are all less than the first threshold, then the adjacent judgment results of the first network base stations of the multiple terminals are determined to be adjacent.

[0082] When making an ATG network base station neighbor judgment, the signal strength of the ATG base station connected to each ATG airborne terminal and the signal strength of the adjacent base stations of the connected ATG base station are obtained from the flight information of the ATG airborne terminal; the ATG base station connected to the ATG airborne terminal can obtain the signal strength of the connected ATG base station and the signal strength of the adjacent base stations around the connected ATG base station when communicating with the ATG airborne terminal. Next, after obtaining the connected ATG base station, the geographical location information of the connected ATG base station can be obtained, such as the latitude and longitude coordinates of the ATG base station. Finally, based on the signal strength of the connected ATG base station and the signal strength of the adjacent base stations of the connected ATG base station, as well as the geographical location information of the connected ATG base station, the ATG base station neighbor judgment result on the ground is determined.

[0083] Specifically, to determine the adjacent judgment result of the ATG base station on the ground, it is first necessary to subtract the signal strength of the ATG base station connected to each ATG airborne terminal from the signal strength of the adjacent base station to obtain the signal strength difference of each ATG airborne terminal; then determine whether the geographical location of the ATG base station corresponding to each ATG recording terminal in the multiple ATG airborne terminals is less than a first threshold. The first threshold can be set to 10 kilometers, for example. When the signal strength difference of two or more ATG airborne terminals is equal, and the geographical distance of the ATG base stations connected to the above multiple ATG airborne terminals is less than the first threshold, then the ATG base station adjacent judgment results of the above multiple ATG airborne terminals are determined to be adjacent. The above is based on the fact that the ATG airborne terminal is only connected to a single AGT base station at the same time, and whether the ATG base stations on the ground are adjacent is determined.

[0084] As shown in FIG. 7 , in an embodiment, determining the distance determination results of the multiple terminals based on the flight information of the multiple terminals in step 504 may include:

[0085] Step 702: Determine, based on the flight information of the multiple terminals, the spatial distances between the multiple terminals, the horizontal distances between the projections of the multiple terminals on the ground, and the altitude distances between the multiple terminals.

[0086] Step 704: Determine distance judgment results of the multiple terminals according to the spatial distances between the multiple terminals, the horizontal distances between the projections of the multiple terminals on the ground, and the height distances between the multiple terminals.

[0087] The specific process of step 704 may include:

[0088] comparing the spatial distances between the multiple terminals with a second threshold, comparing the horizontal distances between the ground projections of the multiple terminals with a third threshold, and comparing the height distances between the multiple terminals with a fourth threshold;

[0089] If the spatial distance between the multiple terminals is less than the second threshold, the horizontal distance between the ground projections of the multiple terminals is less than the third threshold, and the height distance between the multiple terminals is less than the fourth threshold, then the distance judgment result of the multiple terminals meets the distance condition.

[0090] In an embodiment, when performing distance judgment of an ATG airborne terminal, position information, altitude information, speed information and route information are obtained from the flight information of the ATG airborne terminal, and the spatial distance between multiple ATG terminals and the horizontal distance between multiple ATG airborne terminals on the ground projections and the height distance between multiple ATG airborne terminals are calculated using the position information, altitude information, speed information and route information. Then, the distance judgment results of multiple ATG airborne terminals are obtained based on the spatial distance between multiple ATG terminals and the horizontal distance between multiple ATG airborne terminals on the ground projections and the height distance between multiple ATG airborne terminals. Specifically, the distance judgment results of the above-mentioned multiple ATG airborne terminals, the judgment process includes: first, comparing the spatial distance between the multiple ATG airborne terminals with the size of the second threshold, for example, the second threshold is 8 kilometers, the spatial distance between the multiple ATG airborne terminals can be calculated through multiple coordinate systems such as the ground coordinate system, the projectile coordinate system, the ballistic coordinate system and the velocity coordinate system, and then comparing the horizontal distance between the ground projections of the multiple ATG airborne terminals with the size of the third threshold, for example, the third threshold is 9 kilometers, and finally comparing the height distance between the multiple ATG airborne terminals with the size of the fourth threshold, for example, the fourth threshold is 1 kilometer. If the spatial distance between the multiple ATG airborne terminals is less than the second threshold and the horizontal distance between the ground projections of the multiple ATG airborne terminals is less than the third threshold and the height distance between the multiple ATG airborne terminals is less than the fourth threshold, then the distance judgment result of the multiple ATG airborne terminals meets the distance conditions. The above is a judgment of whether the spatial distance of the ATG airborne terminals in the air is close enough.

[0091] In an embodiment, determining the multiple terminals in the same airspace according to the proximity determination result of the first network base station and the distance determination results of the multiple terminals in step 506 may include:

[0092] If the neighbor determination results of the first network base stations of the multiple terminals are neighboring, and / or the distance determination results of the multiple terminals meet the distance condition, it is determined that the multiple terminals are in the same airspace.

[0093] In one case, when the ATG base stations of multiple ATG airborne terminals are judged to be adjacent, it can be determined that the above multiple ATG airborne terminals are in the same airspace. In another case, when the distance judgment results of multiple ATG airborne terminals meet the distance conditions, it can be determined that the above multiple ATG airborne terminals are in the same airspace. In another case, when the ATG base stations of multiple ATG airborne terminals are judged to be adjacent, and the distance judgment results of multiple ATG airborne terminals meet the distance conditions, it can be determined that the above multiple ATG airborne terminals are in the same airspace. In the above manner, multiple ATG airborne terminals in the same airspace can be obtained.

[0094] As shown in FIG8 , in an embodiment, controlling the transmit power of the multiple terminals in the same airspace based on the uplink co-channel interference strength threshold of the second network in step 406 may include:

[0095] Step 802: Acquire an uplink co-channel interference intensity threshold of the second network through an intercommunication link with the second network;

[0096] Step 804: Determine the transmission frequency band of the terminal in the same airspace according to the uplink co-channel interference strength threshold of the second network;

[0097] Step 806: Determine the transmit power of the terminals in the same airspace based on the transmit frequency bands of the terminals in the same airspace; the single uplink co-channel interference corresponding to the transmit power of each terminal in the same airspace does not exceed the uplink co-channel interference intensity threshold of the second network, and the uplink co-channel interference generated by the superposition of the transmit powers of each terminal in the same airspace does not exceed the uplink co-channel interference intensity threshold of the second network;

[0098] Step 808: Send the transmission frequency band of the terminals in the same airspace and the transmission power of the terminals in the same airspace as control instructions to the terminals in the same airspace to control the terminals in the same airspace to operate according to the transmission power on the transmission frequency band.

[0099] An intercommunication link is configured between the ATG network and the IMT network. The IMT network calculates the maximum acceptable uplink co-channel interference intensity for each cell in the IMT network based on historical uplink co-channel interference data, and obtains the IMT network uplink co-channel interference intensity threshold. Next, based on the IMT network uplink co-channel interference intensity threshold, the transmit frequency band of the ATG airborne terminal in the same airspace is calculated. Next, based on the transmit frequency band of the ATG airborne terminal in the same airspace, the transmit power of the ATG airborne terminal in the same airspace is determined. Finally, the transmit frequency band of the ATG airborne terminal in the same airspace and the transmit power of the ATG airborne terminal in the same airspace are sent as control instructions to the ATG airborne terminal in the same airspace. The ATG airborne terminal in the same airspace receives the above control instructions, operates according to the transmit frequency band and transmit power in the control instructions, and communicates with the IMT network.

[0100] As shown in Figure 9, when power control is not performed on the ATG airborne terminals in the same airspace, that is, before power control, the ATG airborne terminals in the same airspace include: ATG UE1 (the first ATG airborne terminal) and ATG UE2 (the second ATG airborne terminal). ATG UE1 and ATG UE2 are allocated the same transmit frequency band F1, the total transmit power of ATG UE1 is P1, and the total transmit power of ATG UE2 is P2, and neither exceeds the maximum transmit power Pmax of the ATG airborne terminals. At this time, the interference strengths caused to the IMT base station are I1 and I2 respectively. I1 and I2 are respectively less than the acceptable uplink co-channel interference strength threshold Imax of the IMT network. However, after I1 and I2 are superimposed on the frequency band F1, the interference strength I1+I2 exceeds Imax, which will cause the performance of the IMT network to degrade, resulting in delays, freezes or packet loss, resulting in reduced network service quality.

[0101] As shown in Figure 10, after power control is performed using the power control method of the present invention, that is, after power control, ATG UE1 and ATG UE2 are allocated the same frequency band F2, and F2 is greater than F1. Due to the increase in the frequency band, the total transmission power is reduced to P11 and P22, respectively. At this time, the interference intensity caused to the IMT base station is I11 and I22, respectively. I11 and I22 are respectively less than the uplink co-channel interference intensity threshold Imax acceptable to the IMT network, and after I11 and I22 are superimposed on the frequency band F2, the interference intensity I11+I22 does not exceed Imax.

[0102] By using the IMT network's uplink co-channel interference intensity threshold as a constraint, the transmission power of multiple ATG airborne terminals in the same airspace can be jointly adjusted, so that the uplink co-channel interference generated by the superposition of the transmission power of multiple ATG airborne terminals in the same airspace does not exceed the IMT network's uplink co-channel interference intensity threshold. This reduces the co-channel interference of multiple ATG airborne terminals in the same airspace to the uplink of the IMT network in the same frequency band after the superposition of ground interference signals. This solves the problem of increased co-channel interference in the IMT network caused by the superposition of transmission power of multiple ATG airborne terminals in the same frequency band. Furthermore, while solving the uplink co-channel interference problem, the co-channel deployment scheme of the ATG network and the IMT network can save radio spectrum resources, expand the operator's business scope, and enhance its influence.

[0103] In an embodiment, in order to evaluate the uplink interference of the ATG airborne terminal to the IMT network cell, the power control method further includes: obtaining the uplink interference information of the second network; the uplink interference information of the second network includes: the location information of the second network base station, the antenna parameter information of the second network cell; the antenna parameter information of the second network cell includes: antenna azimuth, antenna downtilt angle, antenna pattern; according to the flight information of the multiple terminals and the uplink interference information of the second network, determining the uplink co-frequency interference results of the multiple terminals on the second network cell. Specifically, after power control is performed on multiple ATG airborne terminals, it is necessary to further determine whether the uplink interference of the ATG recorded terminal to the IMT network cell has been reduced. The uplink interference information of the IMT network includes the location information of the IMT base station, the antenna parameter information of the IMT network cell, and the antenna parameter information of the IMT network cell includes at least: antenna azimuth angle, antenna downtilt angle and antenna pattern. Next, the co-frequency interference results of multiple ATG airborne terminals on the uplink of the IMT network cell can be determined based on the flight information of the multiple ATG airborne terminals and the uplink interference information of the IMT network cell.

[0104] As shown in FIG11 , in an embodiment, the above-mentioned determining, based on the flight information of the multiple terminals and the uplink interference information of the second network, the uplink co-channel interference results of the multiple terminals on the second network cell includes:

[0105] Step 1102: Determine a transmit beam of the second network base station according to the location information of the second network base station and the antenna azimuth, antenna downtilt angle, and antenna pattern;

[0106] Step 1104: Determine a transmit beam for each of the multiple terminals based on the flight information of the multiple terminals.

[0107] Step 1106: Determine the co-channel interference results of the multiple terminals on the uplink of the second network cell based on the angle between the transmission beam of the second network base station and the transmission beam of each of the multiple terminals. The closer the angle is to 180 degrees, the stronger the co-channel interference result.

[0108] The co-channel interference results of multiple ATG airborne terminals on the uplink of the IMT network cell are mainly affected by the angle between the transmit beam of the ATG airborne terminal and the transmit beam of the IMT network base station. First, the transmit beam of the IMT network base station is determined based on the location information of the IMT network base station and the antenna azimuth, antenna downtilt angle and antenna pattern. The transmit beam of each of the multiple ATG airborne terminals is determined based on the flight information of the multiple ATG airborne terminals. The co-channel interference results of multiple ATG airborne terminals on the uplink of the IMT network cell are determined based on the angle between the transmit beam of the IMT network base station and the transmit beam of each of the multiple ATG airborne terminals. The closer the angle is to 180 degrees, the stronger the co-channel interference result is, and the closer the angle is to 0 degrees, the weaker the co-channel interference result is. Specifically, when the transmit beam of the ATG airborne terminal forms a straight line with the transmit beam of the IMT network base station, the beams are relative, and the generated uplink co-channel interference result is the strongest. When the angle between the transmit beam of the ATG airborne terminal and the transmit beam of the IMT network base station is between 180 degrees and 0 degrees, and the angle approaches 0 degrees, the generated uplink co-channel interference result is the weakest. By calculating the uplink co-channel interference results of multiple ATG airborne terminals on the IMT network cell, it is determined whether the uplink co-channel interference generated by multiple ATG airborne terminals has been reduced to below the uplink co-channel interference intensity threshold. In order to further reduce the uplink co-channel interference of multiple ATG airborne terminals on the IMT network cell, the calculated uplink co-channel interference results of multiple ATG airborne terminals on the IMT network cell can be fed back to the ATG network, and further power control can be performed on the multiple ATG airborne terminals to achieve further reduction of the uplink co-channel interference generated by multiple ATG airborne terminals. The present disclosure provides a method for joint uplink power control of multiple ATG terminals in the same airspace; an ATG network uplink power control method with the goal of reducing co-frequency interference in the uplink of ground IMT cells; and an evaluation method for ground IMT cells affected by co-frequency interference in the uplink of ATG terminals. Aiming at the scenario where the airborne mobile ATG network and the uplink of the IMT network are deployed at the same frequency, and there are multiple ATG airborne terminals connected to multiple ATG base stations in the same airspace, a multi-terminal joint uplink power control method is proposed. This method reduces the co-frequency interference of the uplink of the IMT network in the same frequency band after the superposition of the ground interference signals of the above-mentioned multiple ATG airborne terminals by jointly adjusting the transmission power of multiple ATG airborne terminals, thereby solving the problem of increased co-frequency interference in the ground IMT network due to the superposition of the transmission power of multiple ATG terminals in the same frequency band.

[0109] The present disclosure is applied to the scenario where the ATG network and the IMT network are deployed on the same frequency, especially the scenario where there is uplink co-frequency interference between the ATG network and the IMT network. The present disclosure can also be applied to the joint system design of the ATG network and the IMT network deployed on the same frequency. It will help reduce the interference of the ATG network on the uplink of the terrestrial IMT network and enhance the availability of the co-frequency ATG network. The co-frequency deployment scheme of the airborne mobile ATG network and the IMT network greatly saves radio spectrum resources, and also avoids risks for the accelerated commercialization of the ATG system. The innovative deployment of the co-frequency ATG network has greatly expanded the business scope of operators and greatly enhanced the brand influence of operators.
