Integrated air-ground-space communications are an ideal solution to the problem of limited ground wireless communication coverage.

[0140] S201: Obtain a first system energy efficiency of the space node, wherein the first system energy efficiency is related to a transmission rate and a transmission power of N beams included in the space node, and N is a total number of beams of the space node.

[0141] The space node may refer to a node in wireless communication or a node in satellite communication, for example.

[0142] The system energy efficiency can be used to measure the degree of effective utilization of energy used by the system when completing a specific task or providing a specific service. The first system energy efficiency can refer to a system energy efficiency determined in the power allocation process of the embodiment of the present disclosure.

[0143] In the disclosed embodiment, when the first system energy efficiency of the spatial node is obtained, reliable reference information can be provided for the subsequent updating process of the first transmission power, thereby effectively balancing the transmission power and the system energy efficiency.

[0144] S202: Update a first transmission power of an nth beam among N beams of the spatial node at least based on the first system energy efficiency, where n is a positive integer greater than or equal to 1, and n is less than or equal to N.

Each user can use a narrow beam of the same frequency, and since the distance between each user is far enough, the interference between different beams can be ignored. Figure 4 As shown, Figure 4 1 is a schematic diagram of the structure of the satellite communication system proposed in the present disclosure. Assume that there are a total of N beams providing services for corresponding N users. The satellite manages and schedules all beams according to the user's traffic demand and the satellite downlink channel status.

[0154] Assuming there are N beams in total, the reference channel gain from the nth beam to the user is expressed as

[0155]

[0156] in, is the transmit antenna gain of satellite beam n, is the receiving antenna gain of user n. It is used to describe the fast fading part of the channel between beam n and the user, which is usually caused by rain fading or multipath in urban areas. Usually, this part can be modeled as a log-normal distribution, which can be described as use To represent the free space link loss of user n, it can be further described as

[0157]

[0158] Where c is the speed of light, f0 is the carrier frequency, and dn is the distance between the satellite and user n.

[0159] According to Shannon's formula, when the bandwidth is B, the user data rate is

[0160]

[0161] Among them, p n is the power allocated to beam n, and N0 is the noise per unit bandwidth.

[0162] The total power consumption of the satellite antenna payload can be expressed as

[0163]

[0164] Where λ represents the antenna power gain factor, P C Represents the power consumption of the circuit loading the antenna.

[0165] Therefore, the energy efficiency optimization problem defined in the present invention can be expressed as follows

[0166]

[0167] The total rate of all beams is P T is the maximum transmission power of the multi-beam satellite, R th is the data rate threshold from each beam to the user. Condition C1 can constrain the total transmission power of all beams. Constraint C2 can constrain the data rate on each beam to ensure the QoS of the user. Formula (5) is a nominal optimization problem with perfect channel state information.

[0168] However, in actual low-orbit satellite communication scenarios, due to the influence of channel estimation algorithm errors and the complex transmission environment of satellite-to-ground links, it is impossible to accurately obtain the precise channel gains of all space links. Therefore, the actual channel gain h n It can be remodeled as

[0169]

[0170] in, represents the channel gain under the ideal state obtained according to the above formula (1), Δh n represents the channel gain estimation error of the corresponding satellite-to-ground link in the actual communication system, is the corresponding channel gain uncertainty set, which can be expressed as

[0171]

[0172] where δ n represents the upper bound of the parameter uncertainty set, and |·| represents the absolute value. For the traditional multi-beam power allocation algorithm considering perfect channel parameter information, it is assumed that there is no channel estimation error in the algorithm design stage, that is, Δh n=0, such a design will affect the user's communication experience when the channel state changes due to external influences.

[0173] Therefore, the robust resource allocation problem with uncertain channel parameters is introduced based on the optimization model:

[0174]

[0175] Since problem (8) is a question about the transmission power p n There is also a set of channel parameter uncertainties in the form of norms, so the problem is non-convex.

[0176] First, a convex transformation of the channel uncertainty with minimum rate constraint is performed, and according to the worst case criterion and parameter uncertainty set The definition of , we can get the worst case condition Need to meet:

[0177]

[0178] Using the worst-case criterion, we have

[0179]

[0180] Therefore, through the convex transformation of the channel parameter uncertainty, the optimization problem (8) can be transformed into

[0181]

[0182] Among them, the actual total transmission rate of the satellite including the uncertainty of channel parameters is in

[0183] However, since the objective function is about the transmission power p n The fractional programming function of , the problem is still non-convex. Therefore, the Dinkdbach method is used to transform the nonlinear problem to obtain

[0184]

[0185] At this point, the original energy-efficiency-based robust power allocation problem for LEO satellite multi-beams has been transformed into a convex optimization problem, and the following Lagrangian dual decomposition function is established:

[0186]

[0187] Among them, α, β n are non-negative Lagrange multipliers based on the transmit power constraint and rate threshold constraint respectively.

[0188] After finishing, we can get:

[0258] Figure 6 It is a flowchart of another method for determining beam transmission power provided by an embodiment of the present disclosure.

[0259] like Figure 6 As shown, the method may include but is not limited to the following steps:

[0260] S601: Obtain a first system energy efficiency of a spatial node, wherein the first system energy efficiency is related to a transmission rate and a transmission power of N beams included in the spatial node, and N is a total number of beams of the spatial node.

[0261] S602: Allocate a first transmit power to an nth beam among N beams in a tth iteration process according to a first parameter and a first system energy efficiency.

[0262] S603: Determine a second system energy efficiency in the t-th round of iteration according to the first transmit power.

[0263] The description of S601 - S603 can be specifically referred to the above embodiment, which will not be repeated here.

[0264] S604: Determine the total transmit power in the t-th round of iteration according to the N first transmit powers.

[0265] For example, in the embodiment of the present disclosure, when determining the total transmission power in the t-th round of iteration, the N first transmission powers in the t-th round of iteration may be The sum is accumulated and the obtained sum is used as the total transmission power in the t-th iteration process.

[0266] S605: Determine whether the total transmission power is less than or equal to the maximum transmission power of the multi-beam satellite to obtain a first determination result.

[0267] Among them, the maximum transmission power P T , which may refer to the maximum transmission power value rated for the satellite.

[0268] The first determination result may be used to indicate whether the total transmission power is less than or equal to the maximum transmission power of the multi-beam satellite.

[0269] It can be understood that when the total transmission power is greater than the maximum transmission power of the multi-beam satellite, the satellite is in an overloaded state and the stability of the satellite is poor, which may affect the service quality or cause hardware damage. Therefore, in the embodiment of the present disclosure, it is possible to determine whether the total transmission power is less than or equal to the maximum transmission power of the multi-beam satellite to obtain a first determination result, thereby providing a satellite-side judgment basis for the subsequent determination of whether to end the iterative process.

[0270] S606: Determine whether the beam transmission rate of the nth beam in the tth round of iteration is greater than or equal to the user data rate threshold to obtain a second determination result.

[0271] Among them, the user data rate threshold R th , may refer to the data rate threshold for ensuring user service quality.

[0272] The second determination result may be used to indicate whether the beam transmission rate of the nth beam during the tth round of iteration is greater than or equal to the user data rate threshold.

[0273] It is understandable that the ultimate goal of the satellite system is to serve users. Therefore, it is necessary to ensure the quality of service to users during the system optimization process. In the embodiment of the present disclosure, when determining whether the beam transmission rate of the nth beam in the tth round of iteration is greater than or equal to the user data rate threshold value to obtain a second determination result, the second determination result obtained can provide a user-side judgment basis for subsequent determination of whether to end the iteration process.

[0274] S607: Determine whether the number of iteration rounds reaches an iteration round number threshold to obtain a third determination result.

[0275] Among them, the iteration round threshold T max, may refer to a threshold value pre-set for the iterative process in the embodiment of the present disclosure. The iteration round number threshold may be used to control the convergence and computational efficiency of the algorithm.

[0276] The third determination result can be used to indicate whether the current iteration number t reaches the iteration number threshold T max .

[0277] It is understandable that the Lagrange dual decomposition method is an iterative optimization algorithm that gradually optimizes the problem by continuously updating the Lagrange multipliers and dual variables. Each iteration will gradually bring the value of the objective function closer to the optimal solution. However, in the actual solution process, due to the complexity of the problem, the size of the data or the limited computing resources, it may not be possible to achieve an exact optimal solution, but only an approximate solution. In order to avoid an unlimited iterative process and improve computational efficiency, it is necessary to set a threshold for the number of iterations. When the number of iterations reaches the threshold, the algorithm stops iterating and outputs the current result as an approximate solution. This can control the running time of the algorithm and avoid excessive computing time on the one hand; on the other hand, it can ensure that the algorithm reaches a good approximate solution within a reasonable number of iterations.

[0278] S608: Determine a target transmit power corresponding to the nth beam according to the first determination result, the second determination result, and the third determination result.

[0279] In the embodiment of the present disclosure, after determining the first determination result, the second determination result and the third determination result, different scene types can be determined based on the first determination result, the second determination result and the third determination result, so as to determine whether to continue with the next round of iteration process or to output the target transmission power corresponding to the nth beam.

Thus, the reliability and applicability of the beam transmission power determination process can be effectively improved based on the first determination result, the second determination result and the third determination result.

[0285] Optionally, in some embodiments, when determining the target transmit power corresponding to the nth beam based on the first determination result, the second determination result, and the third determination result, if the first determination result is that the total transmit power is less than or equal to the maximum transmission power, and the second determination result is that the beam transmission rate of the nth beam is less than the user data rate threshold, then the t+1th round of iteration is performed.

[0286] Therefore, the target transmit power corresponding to the nth beam can be flexibly determined in personalized application scenarios, thereby effectively improving the adaptability of the obtained target transmit power to the application scenarios.

[0287] In this embodiment, the total transmit power in the t-th round of iteration is determined based on N first transmit powers, and it is determined whether the total transmit power is less than or equal to the maximum transmission power of the multi-beam satellite to obtain a first determination result; it is determined whether the beam transmission rate of the n-th beam in the t-th round of iteration is greater than or equal to the user data rate threshold to obtain a second determination result; it is determined whether the number of iteration rounds reaches the iteration round number threshold to obtain a third determination result; and the target transmit power corresponding to the n-th beam is determined based on the first determination result, the second determination result and the third determination result. Thus, the reliability and applicability of the beam transmit power determination process can be effectively improved based on the first determination result, the second determination result and the third determination result. If the first determination result is that the total transmit power is greater than the maximum transmission power, and the third determination result is that the number of iteration rounds reaches the iteration round number threshold, then the first transmit power is used as the target transmit power corresponding to the nth beam; if the first determination result is that the total transmit power is less than or equal to the maximum transmission power, and the second determination result is that the beam transmission rate of the nth beam is greater than or equal to the user data rate threshold, and the third determination result is that the number of iteration rounds reaches the iteration round number threshold, then the first transmit power is used as the target transmit power corresponding to the nth beam; if the first determination result is that the total transmit power is greater than the maximum transmission power, and the third determination result is that the number of iteration rounds does not reach the iteration round number threshold, then the t+1th iteration process is performed, wherein the t+1th iteration process The process is used to determine the target transmit power corresponding to the nth beam.

As a result, the target transmit power corresponding to the nth beam can be flexibly determined in personalized application scenarios, thereby effectively improving the adaptability of the obtained target transmit power to the application scenarios.

[0288] For example, Figure 7 As shown, Figure 7 is a flow chart of a low-orbit satellite multi-beam robust power allocation method based on energy efficiency proposed in the present disclosure, such as Figure 7 As shown, the following steps are included:
