[0044] The specific embodiments of the present application are described in further detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0045] In remote areas such as mountainous areas, intelligent reflecting surfaces can assist signal transmission, change the wireless propagation environment of signals, make the wireless environment conducive to data transmission of signals, and thus enable the establishment of connections between base stations. At present, intelligent reflecting surfaces contain a large number of passive intelligent reflecting units, each of which can independently adjust the amplitude and phase. However, when the intelligent reflecting surface assists signal transmission and establishes connections between base stations, the use of intelligent reflecting units is indefinite, which can easily cause unstable transmission and transmission interruption, thereby reducing the transmission efficiency.

[0046] In view of the problems in the prior art, an embodiment of the present application provides an intelligent reflecting unit selection method, device, base station and storage medium for a digital power system, to select an optimal intelligent reflecting unit, and use the optimal intelligent reflecting unit for data transmission between a transmitting base station and a receiving base station, thereby improving the stability of the transmission process, reducing the transmission interruption, and improving the transmission efficiency.

[0047] Referring to Figure 1 , Figure 1 is a flowchart of an intelligent reflecting unit selection method for a digital power system provided by an embodiment of the present application.

[0048] In an embodiment of the present application, the intelligent reflecting surface deployed on the power tower assists signal transmission, and the signal is forwarded by the intelligent reflecting surface, so that the transmitting base station and the receiving base station can establish a connection and perform data transmission. The intelligent reflecting unit selection method for a digital power system described below in the embodiment of the present application is explained and described in relation to the foregoing.

[0049] In one embodiment, the present application provides an intelligent reflecting unit selection method for a digital power system, comprising the following steps:

[0050] Step S110, obtaining reflection channel parameter information corresponding to a plurality of intelligent reflecting units in the intelligent reflecting surface.

[0051] In an embodiment, the reflection channel parameter information corresponding to each of the acquired smart reflecting elements can include first reflection channel parameter information and second reflection channel parameter information, wherein the first reflection channel parameter information is reflection channel parameter information from the sending base station to a certain smart reflecting element, and the second reflection channel parameter information is reflection channel parameter information from the certain smart reflecting element to the receiving base station.

[0052] It can be understood that, taking the first smart reflecting element and the second smart reflecting element as examples, the first reflection channel parameter information corresponding to the first smart reflecting element is reflection channel parameter information from the sending base station to the first smart reflecting element, and the second reflection channel parameter information corresponding to the first smart reflecting element is reflection channel parameter information from the first smart reflecting element to the receiving base station; the first reflection channel parameter information corresponding to the second smart reflecting element is reflection channel parameter information from the sending base station to the second smart reflecting element, and the second reflection channel parameter information corresponding to the second smart reflecting element is reflection channel parameter information from the second smart reflecting element to the receiving base station.

[0053] In an embodiment, when the receiving base station acquires the reflection channel parameter information corresponding to the plurality of smart reflecting elements in the smart reflecting surface, the receiving base station can send a pilot signal to the smart reflecting surface by the sending base station, and the receiving base station estimates and obtains the reflection channel parameter information corresponding to the plurality of smart reflecting elements in the smart reflecting surface according to the corresponding received signal and the pilot information.

[0054] In step S120, the offloading delay corresponding to each smart reflecting element is calculated according to the transmission task.

[0055] In an embodiment, when the receiving base station calculates the offloading delay corresponding to each smart reflecting element according to the transmission task, the transmission delay corresponding to each smart reflecting element and the calculation delay can be calculated according to the transmission task; and then the offloading delay corresponding to each smart reflecting element is calculated according to the transmission delay corresponding to each smart reflecting element and the calculation delay.

[0056] In the embodiment, when the receiving base station calculates the transmission delay corresponding to each smart reflecting element and the calculation delay according to the transmission task, the transmission delay corresponding to each smart reflecting element can be calculated according to the transmission task size and the transmission rate of the smart reflecting element; and the calculation delay corresponding to each smart reflecting element can be calculated according to the transmission task size, the predetermined number of periods and the base station calculation capability.

[0057] Optionally, the transmission task size can be obtained by the receiving base station through a dedicated feedback channel.

[0058] Specifically, the calculation formula of the transmission delay corresponding to each smart reflecting element is as follows:

[0059]

[0060] wherein T t is the transmission latency of the intelligent reflecting unit, K is the transmission task size, R n is the transmission rate of the intelligent reflecting unit, the calculation formula of the transmission rate R n of the intelligent reflecting unit is as follows:

[0061] R n = log2(1 + SNR n )

[0062] wherein SNR n is the transmission signal-to-noise ratio, which can be expressed as follows:

[0063]

[0064] wherein P is the transmission power, |h 1,n | 2 is the reflection channel parameter information from the sending base station to a certain intelligent reflecting unit, |h 2,n | 2 is the reflection channel parameter information from the above certain intelligent reflecting unit to the receiving base station, σ 2 is the variance of the noise.

[0065] The calculation formula of the calculation latency corresponding to each intelligent reflecting unit is as follows:

[0066]

[0067] wherein T c is the calculation latency of the intelligent reflecting unit, w is the number of periods for the processor to receive the calculation of each bit, and F is the calculation capability of the receiving base station.

[0068] In this embodiment, the receiving base station calculates the offloading latency corresponding to each intelligent reflecting unit according to the sum of the transmission latency and the calculation latency corresponding to each intelligent reflecting unit, that is, the calculation formula of the offloading latency corresponding to each intelligent reflecting unit is as follows:

[0069] T n = T t + T c

[0070] wherein T n is the offloading latency of the intelligent reflecting unit.

[0071] In one embodiment, the offloading delay corresponding to each smart reflecting unit is calculated more accurately by the transmission delay corresponding to each smart reflecting unit and the calculation delay, and the transmission delay and the calculation delay are calculated more accurately by the calculation manner of the transmission delay and the calculation delay, so that the optimal smart reflecting unit can be selected more accurately.

[0072] In step S130, the transmission interruption probability corresponding to each smart reflecting unit is calculated according to the offloading delay corresponding to each smart reflecting unit.

[0073] In one embodiment, when the receiving base station calculates the transmission interruption probability corresponding to each smart reflecting unit according to the offloading delay corresponding to each smart reflecting unit, the transmission interruption probability corresponding to each smart reflecting unit can be calculated according to the offloading delay corresponding to each smart reflecting unit and the preset delay threshold.

[0074] In this embodiment, when the transmission interruption probability corresponding to the smart reflecting unit is greater than the preset delay threshold, the system transmission is interrupted, otherwise, when the transmission interruption probability corresponding to the smart reflecting unit is less than or equal to the preset delay threshold, the system transmission is not interrupted, and the relationship of the transmission interruption probability corresponding to each smart reflecting unit can be expressed as follows:

[0075] P out = Pr(T n > T th )

[0076] Wherein, P out is the transmission interruption probability corresponding to the smart reflecting unit, and T th is the preset delay threshold.

[0077] In step S140, the optimal smart reflecting unit is selected according to the transmission interruption probability and the reflecting channel parameter information.

[0078] In one embodiment, the selected optimal smart reflecting unit is used for data transmission between the sending base station and the receiving base station.

[0079] In one embodiment, when the receiving base station selects the optimal smart reflecting unit according to the transmission interruption probability and the reflecting channel parameter information, the smart reflecting unit with transmission interruption can be excluded according to the transmission interruption probability; the optimal smart reflecting unit is selected according to the remaining smart reflecting unit and the corresponding reflecting channel parameter information.

[0080] In this embodiment, when the receiving base station selects the optimal smart reflecting unit according to the remaining smart reflecting unit and the corresponding reflecting channel parameter information, the optimal smart reflecting unit can be selected according to the maximum value of the product of the first reflecting channel parameter information and the second reflecting channel parameter information corresponding to the remaining smart reflecting unit.

[0081] Specifically, the way of selecting the optimal smart reflecting unit can be represented as follows:

[0082]

[0083] wherein H n is the gain product of the first reflection channel parameter information and the second reflection channel parameter information corresponding to the smart reflecting unit, H n = |h 1,n | 2 | h 2,n | 2 .

[0084] In the embodiment, when the receiving base station selects the optimal smart reflecting unit according to the remaining smart reflecting units and the corresponding reflection channel parameter information, the receiving base station can select the optimal smart reflecting unit according to the maximum value of the gain of the first reflection channel parameter information corresponding to the remaining smart reflecting units.

[0085] Specifically, the way of selecting the optimal smart reflecting unit can be represented as follows:

[0086]

[0087] In one embodiment, the optimal smart reflecting unit can be selected by the above-mentioned way to be used for data transmission between the sending base station and the receiving base station.

[0088] The above-mentioned smart reflecting unit selection method for digital power system calculates the unloading delay corresponding to each smart reflecting unit through the transmission task, calculates the transmission interruption probability corresponding to each smart reflecting unit, and then selects the optimal smart reflecting unit according to the transmission interruption probability and the reflection channel parameter information corresponding to the smart reflecting unit, so as to use the optimal smart reflecting unit for data transmission between the sending base station and the receiving base station, thereby improving the stability of the transmission process, reducing the interruption of the transmission, and improving the efficiency of the transmission.

[0089] For this purpose, reference can be made to Figures 2 to 4 , Figures 2 to 4 are schematic diagrams of the influence of interruption probability under different transmission power, time delay threshold, and transmission task size, wherein the approximate result is obtained under a certain signal-to-noise ratio, which can help to observe the explicit change rule of system performance under high signal-to-noise ratio, the analysis result is obtained by mathematical deduction, and the experimental result is obtained to verify the correctness of the analysis result. Figure 2As can be seen from the above, the analysis result is completely matched with the experimental result, indicating that the calculation formula of the transmission interruption probability adopted by the intelligent reflecting unit selection method for the digital power system is effective; in addition, the effectiveness of the intelligent reflecting unit selection method for the digital power system is also indicated; from Figure 3 As can be seen from the above, the analysis result is basically consistent with the experimental result, indicating the reliability of the intelligent reflecting unit selection method for the digital power system; from Figure 4 As can be seen from the above, when the transmission task bit number increases, the transmission interruption probability increases, because the increase of the transmission task leads to the increase of the offloading delay, in addition, the asymptotic performance of the optimal intelligent reflecting unit selected by the intelligent reflecting unit selection method for the digital power system decreases with the increase of the transmission task, indicating that the transmission task bit number will also affect the asymptotic performance, at the same time, the analysis result is well matched with the experimental result output, indicating the effectiveness of the intelligent reflecting unit selection method for the digital power system.
