Detailed Implementation

[0013] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0014] Figure 1 This illustration shows a flowchart of a method for adjusting the transmit power of a satellite communication terminal according to an exemplary embodiment of this application. This method can be executed by an electronic device, such as a satellite communication terminal. Figure 1 As shown, the method mainly includes the following steps: S101: Based on historical environmental loss data, determine the predicted environmental loss data for the first time period.

[0015] In this embodiment, environmental loss prediction data for the first time period can be determined based on historical environmental loss data. In practical applications, the signal quality between the satellite communication terminal and the satellite is affected by weather conditions, especially in high-frequency communication bands. Atmospheric conditions such as rainfall and clouds can significantly attenuate the signal, leading to a decline in communication link quality and making it difficult to meet stable signal-to-noise ratio requirements. In practical applications, environmental loss can include atmospheric loss and rain attenuation loss, and historical environmental loss data can include historical data on atmospheric loss and rain attenuation loss. The length of the first time period can be 1 minute or 2 minutes, and can be determined according to the actual situation; this embodiment does not impose a specific limitation.

[0016] In this embodiment of the application, environmental loss in the first time period can be predicted based on historical environmental loss data to obtain environmental loss prediction data for the first time period. Then, in subsequent steps, the transmission power of the satellite communication terminal can be adjusted based on the environmental loss prediction data for the first time period to ensure communication quality.

[0017] S102: Determine the predetermined transmission power of the satellite communication terminal during the first time period based on the first loss in the environmental loss prediction data.

[0018] In this embodiment, the predetermined transmission power of the satellite communication terminal within a first time period can be determined based on the first loss in the environmental loss prediction data. By incorporating environmental loss within the first time period as an influencing factor into the predetermined transmission power of the satellite communication terminal within the first time period, based on the first loss in the environmental loss prediction data, the communication quality within the first time period can be guaranteed, ensuring that it is not affected by severe weather.

[0019] S103: Adjust the transmission power of the satellite communication terminal to transmit signals to the satellite during the first time period according to the predetermined transmission power.

[0020] In this embodiment, the transmission power of the satellite communication terminal transmitting signals to the satellite within a first time period can be adjusted according to a predetermined transmission power. This embodiment allows for real-time adjustment of the satellite communication terminal's transmission power, avoiding the problem of power adjustment relying primarily on fixed link budget parameters and lagging response to dynamic changes in meteorological conditions (such as rain attenuation and atmospheric conditions). It also avoids the issue of related solutions often setting higher transmission power to cope with potential environmental losses due to the inability to adjust power in real time, thus increasing energy consumption and hindering resource conservation. In this embodiment, adjusting the predetermined transmission power obtained through environmental loss prediction in advance ensures signal quality during continuous communication under dynamic meteorological conditions.

[0021] The technical solution provided in this application allows for the determination of predicted environmental loss data for a first time period based on historical environmental loss data. Then, based on the first loss in the predicted environmental loss data, a predetermined transmission power for the satellite communication terminal within the first time period is determined. Finally, based on the predetermined transmission power, the transmission power of the satellite communication terminal transmitting signals to the satellite within the first time period is adjusted. By predicting environmental loss, the transmission power of the satellite communication terminal can be adjusted in a timely manner to adapt to changing weather conditions and ensure communication quality.

[0022] In an optional implementation, S101 above may include the following steps: Step 1011: Input the historical environmental loss data and the meteorological data corresponding to the historical loss data into the environmental loss prediction model to obtain the environmental loss prediction data at the first moment, wherein the first moment is the moment within the first time period.

[0023] In this embodiment, historical environmental loss data and corresponding meteorological data can be input into the environmental loss prediction model to obtain the environmental loss prediction data for the first moment within the first time period. In practical applications, the environmental loss prediction model can use a Long Short-Term Memory (LSTM) network architecture. LSTM is a special type of recurrent neural network that can solve the gradient vanishing and gradient exploding problems that traditional recurrent neural networks cannot effectively handle when dealing with long sequences.

[0024] Step 1012: Determine the environmental loss prediction data for the first time period based on multiple environmental loss prediction data at the first moment.

[0025] In this embodiment of the application, environmental loss prediction data corresponding to the first time period can be obtained based on environmental loss prediction data at multiple first moments within the first time period.

[0026] In practical applications, step 1011 above can be based on historical environmental loss data and meteorological data corresponding to the historical environmental loss data. Calculate the environmental losses in the first moment of the future. Meteorological data can include parameters such as air pressure, humidity, and rainfall. The specific steps are as follows: The first step is to obtain an environmental degradation prediction model. This begins by collecting historical environmental degradation values ​​and corresponding meteorological data for model training, establishing a training database, and dividing it into training and validation sets based on time series data while maintaining the chronological order of the data. Then, based on the collected data, an LSTM model architecture is built, and iterative training is performed using the training and validation sets to form a model. The model takes historical environmental degradation values ​​and corresponding meteorological data as input and outputs environmental degradation values ​​at the first moment in the future.

[0027] The second step is environmental loss prediction. In practical applications, this can be based on... It predicts the environmental loss value at the first moment in the future.

[0028]

[0029] In practical applications, predictions can be made at the minute or second level; however, this application does not impose any specific limitations on the specific timeframes.

[0030] In an optional implementation, the first loss in S102 above can be the loss data with the largest value among all the environmental loss data. In this embodiment, S102 may include the following steps: Step 1021: Determine the second loss based on the link budget information between the satellite communication terminal and the satellite, wherein the second loss is the loss data in the communication link between the satellite communication terminal and the satellite excluding environmental losses.

[0031] In this embodiment, a second loss, excluding environmental losses, can be determined in the communication link between the satellite communication terminal and the satellite based on the link budget information between the satellite communication terminal and the satellite. In practical applications, this second loss... This can include path loss and polarization loss .

[0032] In practical applications, path loss This represents the fundamental loss of a signal during propagation, determined by the propagation distance and frequency. For example, the calculation formula is:

[0033] in, d This indicates the distance (in km) from the satellite communication terminal to the satellite. f This represents the uplink communication frequency (in MHz), with a constant of 32.4 used for unit conversion.

[0034] Polarization loss This is a fixed loss caused by the polarization mismatch between the terminal's transmitting antenna and the satellite receiving antenna, which can be calculated by the terminal using satellite antenna parameters and terminal antenna status. Polarization direction refers to the direction of the electric field vector in an electromagnetic wave. By summing up all the losses, we can obtain the second loss in the link besides environmental losses:

[0035] Step 1022: Determine the uplink power based on the channel state information between the satellite communication terminal and the satellite and the target signal-to-noise ratio.

[0036] In this embodiment of the application, the uplink power can be determined based on the channel state information between the satellite communication terminal and the satellite and the target signal-to-noise ratio.

[0037] Uplink power typically refers to the power level required for terminal equipment to transmit signals to a satellite in order to ensure that the signal can be effectively received by the satellite.

[0038] In practical applications, channel state information can be collected from the system, including satellite noise power density. (Background noise power density, used to calculate noise power) and bandwidth B (channel bandwidth (in Hz), combined with noise power density to obtain total noise power).

[0039] In practical applications, a target signal-to-noise ratio can also be set. ,based on Calculate the power of satellite launch Signal-to-noise ratio (SNR) is a commonly used metric for measuring signal quality, defined as the ratio of signal power to noise power. In this embodiment, the target SNR can be a desired signal quality. For example, the calculation formula is as follows:

[0040] Step 1023: Determine the predetermined transmission power of the satellite communication terminal within the first time period based on the first loss, the second loss, and the satellite uplink power in the environmental loss prediction data.

[0041] In this embodiment, the predetermined transmission power of the satellite communication terminal within a first time period can be determined based on the first loss with the largest value in the environmental loss prediction data, the second loss in the communication link between the satellite communication terminal and the satellite (excluding environmental loss), and the uplink power. For example, the predetermined transmission power... The calculation formula is as follows:

[0042] in, It is the antenna gain of the satellite communication terminal, which can be used to offset some of the link loss.

[0043] In practical applications, the above formula takes into account various losses, which can ensure that the final transmission power can offset the energy attenuation during transmission and guarantee that the signal meets the satellite's quality requirements.

[0044] In an optional implementation, S103 above may include the following steps: Step 1031: Determine the first transmission power of the satellite communication terminal transmitting signals to the satellite based on the predetermined transmission power, wherein the first transmission power is greater than or equal to the predetermined transmission power.

[0045] In this embodiment of the application, the first transmission power of the satellite communication terminal to transmit signals to the satellite can be determined according to the predetermined transmission power. It should be noted that the first transmission power can be greater than or equal to the predetermined transmission power to ensure communication quality.

[0046] Step 1032: Adjust the transmission power of the satellite communication terminal to transmit signals to the satellite during the first time period according to the first transmission power.

[0047] In this embodiment of the application, the transmission power of the satellite communication terminal transmitting signals to the satellite within a first time period can be adjusted according to the first transmission power.

[0048] In practical applications, using the first transmission power as the transmission power of the satellite communication terminal in the first time period can not only ensure communication quality and avoid the impact of severe weather on communication, but also avoid excessive power adjustment and significantly reduce the power consumption of the system.

[0049] In an alternative implementation, after S103, the method may further include the following steps: Step 104: At the second moment within the first time period, determine the second transmission power corresponding to the second time period after the third moment, wherein the second moment is before the third moment, and the duration required to determine the second transmission power is less than or equal to the time difference between the third moment and the second moment, and the length of the first time period is the same as the length of the second time period.

[0050] In this embodiment, the second transmission power corresponding to the second time period after the third time period can be determined at the second time point within the first time period. For example, assuming the first time period is the 1st minute, the second transmission power from the 50th second to the 1st minute and 50th second can be calculated at the 45th second. This design incorporates an overlapping portion within the continuously predicted period, which not only avoids prediction environmental degradation and ensures communication quality, but also acts as a buffer zone for power adjustment, ensuring that the satellite communication terminal can complete power adjustment.

[0051] Step 105: Adjust the transmission power of the satellite communication terminal to transmit signals to the satellite during the second time period according to the second transmission power.

[0052] In this embodiment of the application, the transmission power of the satellite communication terminal transmitting signals to the satellite during the second time period can be adjusted according to the second transmission power, so as to ensure the communication quality during the second time period.

[0053] In an alternative implementation, after S103, the method may further include the following steps: In response to the adjustment request sent by the satellite, the transmission power of the satellite communication terminal transmitting signals to the satellite is adjusted again.

[0054] In this embodiment, the transmission power of the satellite communication terminal transmitting signals to the satellite can be readjusted in response to an adjustment request sent by the satellite. In practical applications, after power adjustment is completed, a feedback mechanism can be used for real-time adjustment to ensure that the transmission power meets the actual channel requirements.

[0055] In practical applications, satellites can compare their actual launch power with a given launch power based on the target signal-to-noise ratio to calculate the error.

[0056] If error If the error exceeds a set threshold, the satellite can notify the satellite communication terminal to adjust the transmission power accordingly. This is to ensure the system can meet communication needs in dynamic environments. In practical applications, if the actual satellite power is significantly greater than the given satellite power based on the target signal-to-noise ratio, it indicates a potential waste of resources. If the actual satellite power is significantly less than the given satellite power based on the target signal-to-noise ratio, it indicates that the transmission power of the satellite communication terminal cannot meet the satellite's requirements, which may affect the normal operation of satellite services. Both require further adjustments.

[0057] In practical applications, the adjustment requests sent by satellites can carry errors. This is to facilitate the determination of the transmission power of the satellite communication terminal transmitting signals to the satellite. It is important to note that the determination of the transmission power in this instance still uses environmental loss data for calculation, and adjustments need to be made based on actual conditions during subsequent transmission power determination processes. For example, if the predetermined transmission power obtained using environmental loss data is P1, and the actual satellite power is significantly lower than the given uplink power based on the target signal-to-noise ratio, the actual transmission power P2 needs to be significantly greater than P1, at least larger than the error, to meet the satellite's communication requirements. In this embodiment, to ensure the robustness of power adjustment, a feedback mechanism can be used for real-time adjustment throughout the communication process to ensure that the transmission power meets the actual channel requirements.

[0058] The satellite communication terminal transmission power adjustment method provided in this application can be executed by a satellite communication terminal transmission power adjustment device. This application uses the satellite communication terminal transmission power adjustment device executing the satellite communication terminal transmission power adjustment method as an example to illustrate the satellite communication terminal transmission power adjustment device provided in this application.
