Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method, system, medium, and device for communication of shore-based base stations assisted by intelligent reflectors. Background Technology

[0002] To realize the integrated air-space-ground-sea network architecture proposed by 6G mobile communication technology, research on marine broadband communication systems is a pressing challenge. Compared to mature terrestrial communication, the development of marine communication is relatively lagging. Specifically, the ocean is a vast, sparsely populated, and relatively open environment. Moreover, the sea has large waves, making it very difficult to deploy dense base stations with low utilization rates. To achieve high-speed communication and increase the utilization of frequency bands, it is necessary to deploy relatively dense base stations on land.

[0003] However, signal propagation at sea faces different challenges than on land, as signals are affected by wave motion and waveguide effects. Currently, most marine communications use omnidirectional antennas, resulting in relatively low antenna gain and impacting received signal strength. To achieve higher communication rates, the currently used communication frequency bands attenuate relatively quickly, and the effects of water vapor and oxygen accelerate the attenuation of high-frequency signals. Furthermore, to avoid obstruction by tall buildings, base stations are deployed at higher locations, preventing radio electromagnetic signals from directly utilizing atmospheric waveguides to reduce signal attenuation for long-distance transmission. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a method, system, medium and device for communication of shore-based base stations assisted by intelligent reflectors, in order to solve the problems of small coverage and low communication rate of existing shore-based base stations and the inability to use waveguides for long-distance information transmission because the antenna is not located in the waveguide layer.

[0005] In a first aspect, this application provides a smart reflector-assisted shore-based base station communication method, which includes:

[0006] Obtain meteorological data of the location of the preset shore-based base station and the height value of the transmitting antenna corresponding to the shore-based base station;

[0007] Obtain the range of waveguide layer height values ​​at the location of the shore-based base station;

[0008] Determine whether the height value of the transmitting antenna is within the range of height values, wherein,

[0009] If the height value of the transmitting antenna is not within the range of the height value, the propagation angle and propagation height of the radio electromagnetic wave signal are changed based on the preset intelligent reflective surface;

[0010] If the height value of the transmitting antenna is within the range of the height value, the propagation angle of the radio electromagnetic wave signal is changed based on the intelligent reflective surface.

[0011] This application enhances the coverage of shore-based base stations by inducing radio electromagnetic waves to be trapped in the waveguide layer, and uses a smart reflector to change the propagation angle of the signal so that the signal can propagate a longer distance with low loss, thereby achieving long-distance signal propagation.

[0012] In one possible implementation of this application, the height value of the transmitting antenna is obtained based on the transmitting antenna of the shore-based base station, wherein the transmitting antenna transmits the radio electromagnetic wave signal to the outside world.

[0015] In one possible implementation of this application, the propagation angle of the radio electromagnetic wave signal is changed so that the absolute value of the incident angle of the radio electromagnetic wave signal entering the waveguide layer is less than or equal to the waveguide trapping angle value.

[0016] In one possible implementation of this application, the propagation height of the smart reflective surface is changed based on a preset controllable height device, wherein the controllable height device includes at least a drone.

[0017] Among them, using drones as controllable altitude devices allows for flexible deployment of intelligent reflective surfaces, offering wide adaptability and simple operation.

[0018] Secondly, this application provides a smart reflector-assisted shore-based base station communication system, which includes:

[0019] The acquisition module is used to acquire meteorological data of the location of a preset shore-based base station, the height value of the transmitting antenna corresponding to the shore-based base station, and the range of the height value of the waveguide layer at the location of the shore-based base station.

[0020] The judgment module is used to determine whether the height value of the transmitting antenna is within the height value range. If the height value of the transmitting antenna is not within the height value range, the propagation angle and propagation height of the radio electromagnetic wave signal are changed based on a preset intelligent reflective surface. If the height value of the transmitting antenna is within the height value range, the propagation angle of the radio electromagnetic wave signal is changed based on the intelligent reflective surface.

[0021] Thirdly, this application provides a computer-readable storage medium as described above, on which a computer program is stored, which, when executed by a processor, implements the intelligent reflector-assisted shore-based base station communication method.

[0022] Fourthly, this application provides the above-mentioned electronic device, which includes: a processor and a memory; wherein the memory is used to store a computer program, and the processor is used to load and execute the computer program to enable the electronic device to perform the intelligent reflector-assisted shore-based base station communication method.

[0023] Fifthly, this application provides a shore-based base station communication device assisted by an intelligent reflective surface.

[0024] In this application, the intelligent reflector-assisted shore-based base station communication device includes:

[0025] Such as the aforementioned electronic devices; and

[0026] A shore-based base station is communicatively connected to the electronic device, and the shore-based base station transmits radio electromagnetic wave signals to the outside world based on a transmitting antenna;

[0027] A smart reflective surface, located on one side of the shore-based base station, is used to change the propagation angle of the radio electromagnetic wave signal so that the radio electromagnetic wave signal propagates within the waveguide layer at the location of the shore-based base station.

[0028] A height-controllable device is fixedly connected to the intelligent reflective surface and is used to adjust the propagation height of the intelligent reflective surface.

[0029] As described above, the intelligent reflector-assisted shore-based base station communication method, system, medium, and device of the present invention enhances the coverage of shore-based base stations by inducing radio electromagnetic waves to be trapped in the waveguide layer, and uses the intelligent reflector to change the propagation angle of the signal so that the signal can propagate a longer distance with low loss.

[0047] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0048] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0049] See also Figure 1 In one embodiment of the invention, the intelligent reflector-assisted shore-based base station communication method of the present invention includes the following steps:

[0050] Step S102: Obtain meteorological data of the location of the preset shore-based base station and the height value of the transmitting antenna corresponding to the shore-based base station;

[0051] Step S104: Obtain the range of waveguide layer height values ​​at the location of the shore-based base station;

[0052] Step S106: Determine whether the height value of the transmitting antenna is within the range of height values, wherein,

[0053] Step S108: If the height value of the transmitting antenna is not within the range of the height value, the propagation angle and propagation height of the radio electromagnetic wave signal are changed based on the preset intelligent reflective surface.

[0054] Step S110: If the height value of the transmitting antenna is within the range of the height value, then the propagation angle of the radio electromagnetic wave signal is changed based on the intelligent reflective surface.

[0055] It should be noted that the technical names involved in the technical solution of this application, such as waveguide layer and smart reflector, refer to the waveguide effect, a special atmospheric phenomenon. Electromagnetic waves propagating in the near-Earth layer are affected by atmospheric refraction, causing their propagation trajectory to bend towards the ground. When the curvature exceeds the curvature of the Earth's surface, the electromagnetic waves will be partially trapped in a thin layer of atmosphere of a certain thickness (i.e., waveguide layer). The trapped radio electromagnetic wave signals will be confined within a certain thickness of atmosphere and propagate forward by reflecting back and forth at the upper and lower boundaries, just like propagating in a metal waveguide.

[0056] The advent of waveguides allows radio electromagnetic wave signals to propagate forward with lower path loss, and the propagation distance can reach several times that under normal conditions, enabling long-distance transmission of electromagnetic waves. The refractive index n of a waveguide is expressed as:

[0057]

[0058] Where T represents temperature, P represents pressure, and e represents water vapor pressure.

[0059] Correspondingly, intelligent reflector systems (IRS) consist of a large number of low-cost, subwavelength, tunable electromagnetic components (superatoms) artificially integrated on a plane. The on / off state, capacitance, resistance, and inductance parameters of these components are controlled through software or hardware, thereby controlling the phase and amplitude characteristics of electromagnetic waves. Ultimately, this achieves the goal of reconstructing the wireless propagation environment and providing new spatial degrees of freedom for the system. Compared to traditional active repeaters, intelligent reflector devices have no radio frequency or signal processing components, resulting in lower implementation complexity and cost. Furthermore, intelligent reflectors have lower hardware costs and power consumption. Secondly, intelligent reflectors operate in full-duplex mode, effectively avoiding antenna amplification noise and signal self-interference problems. Finally, intelligent reflectors are typically small, lightweight, and thin, making deployment and replacement more flexible and convenient, thus providing significant flexibility and compatibility for existing wireless communication networks.

[0060] Specifically, the height of the transmitting antenna is obtained based on the transmitting antenna of the shore-based base station. The transmitting antenna transmits radio electromagnetic signals and acquires meteorological data at the location of the preset shore-based base station to calculate the height of the waveguide layer, thereby determining whether the height of the transmitting antenna is within the range of waveguide layer height values. Regarding waveguide effects, statistics show that the main type of waveguide effect in domestic marine environments is evaporative waveguide, with the highest intensity occurring between 8 PM and 8 AM the following morning, with a probability exceeding 90%. The average height of the waveguide layer is 15m, and the average waveguide intensity is 35. The expression for obtaining the waveguide layer height is:

[0061]

[0062]

[0063] Where M represents the atmospheric corrected refractive index, N represents the atmospheric refractive index, h represents the altitude above the ground, R represents the Earth's radius, T represents the temperature, P represents the pressure, and e represents the vapor pressure. Substituting the expression for N into the expression for M, and differentiating the expression for M by h, when... At this time, the height h above the ground is the height h of the waveguide layer. w Therefore, the height of the waveguide layer can be calculated using three meteorological parameters: temperature, pressure, and water vapor pressure. Accordingly, the meteorological data must include at least temperature, pressure, and water vapor pressure.

[0064] Determine whether the height value of the transmitting antenna is within the range of height values. If the height value of the transmitting antenna is not within the range of height values, such as... Figure 2As shown, when the height of the transmitting antenna corresponding to the shore-based base station is higher than the height of the waveguide layer, the propagation angle and height of the radio electromagnetic wave signal are changed based on the preset intelligent reflector. Specifically, the propagation height of the intelligent reflector is changed by the controllable height device, and the propagation angle is changed by the intelligent reflector, so that the radio electromagnetic wave signal can enter the waveguide layer and propagate accordingly. Figure 2 The base station is located in a fixed position on the shore. In order to avoid being blocked by other tall buildings such as port containers, reefs and islands, the base station is relatively high. In this case, the deployment of the smart reflector must be close to the base station. This is so that the signal can travel a shorter distance in the air and be trapped in the waveguide layer at a faster speed to reduce attenuation.

[0065] Furthermore, if the height value of the transmitting antenna is within the range of the height values, such as... Figure 3 As shown, at this time, the antenna height value corresponding to the shore-based base station is located in the waveguide layer. Then, based on the intelligent reflective surface, the propagation angle of the radio electromagnetic wave signal is changed, so that the radio electromagnetic wave signal enters the waveguide layer to propagate.

[0066] Furthermore, in one embodiment of the invention, the method further includes changing the downtilt angle of the transmitting antenna transmitting the radio electromagnetic wave signal.

[0067] It should be noted that, in this embodiment, as Figure 3 As shown, when the height of the transmitting antenna corresponding to the shore-based base station is located in the waveguide layer, the propagation angle of the radio electromagnetic wave signal can also be changed by changing the downtilt angle of the transmitting antenna transmitting the radio electromagnetic wave signal.

[0068] Furthermore, in one embodiment of the invention, the method further includes obtaining a waveguide intensity value and calculating a waveguide trapping angle value based on the waveguide intensity value.

[0069] It should be noted that, in this embodiment, the waveguide intensity value can be obtained based on the meteorological data, wherein the waveguide intensity value is ΔM, and correspondingly, the expression for the waveguide trapping angle is... like Figure 4 The figure shows the simulation results relating the critical incident angle and the waveguide intensity. Therefore, the smart reflector also needs to be deployed at a suitable height to induce the signal into the waveguide. The refractive index at the height of the waveguide layer needs to meet the following condition:

[0070] Furthermore, in one embodiment of the invention, the propagation angle of the radio electromagnetic wave signal is changed so that the absolute value of the incident angle of the radio electromagnetic wave signal entering the waveguide layer is less than or equal to the waveguide trapping angle value.

[0071] It should be noted that, in this embodiment, the waveguide trapping angle φ and the average waveguide intensity are described as "35" in the above embodiments, which can be further deduced to be φ = ±8.37 × 10⁻⁶. -3 Rad, further conversion of units yields a waveguide trapping angle φ = 0.4°, such as... Figure 2 As shown, when the height of the transmitting base station and the waveguide layer differ significantly, it is difficult for the incident signal to meet the requirement of less than 0.4°. Therefore, by using a drone or other height-controlled device equipped with a smart reflector, the signal propagation height is first lower than the waveguide layer height (e.g., 13m), and then the signal propagation angle meets the waveguide trapping angle (e.g., ±0.4°). This ensures that the signal propagation angle and height satisfy the waveguide trapping conditions, thereby ensuring that radio electromagnetic signals are induced into the waveguide layer for low-path-loss long-distance transmission, thus expanding the coverage of shore-based base station communications.

[0072] Specifically, in practical applications, the height value of the transmitting antenna is not within the range of the specified height value, such as... Figure 2 As shown, when the height of the transmitting antenna corresponding to the shore-based base station is higher than the height of the waveguide layer, such as Figure 2 As shown, there are two main communication links between the base station and the ship: one where the signal directly reaches the receiver, and another where the signal reaches the receiver via a path assisted by a smart reflector. The direct path is the line-of-sight link where the signal propagates directly in free space and reaches the receiver directly. According to the two-ray path model, the signal reaches the receiver directly in two ways: one is a line-of-sight path from the transmitter to the receiver, and the other is a reflection path. In the case of reflection, sea surface reflection is the primary path, and the signal reaching the receiver through refraction and scattering is relatively weak. In this case, the main function of the smart reflector is to change the signal propagation angle and altitude. For example... Figure 2 As shown, we assume the channel coefficient of the direct path is... The channel coefficient of the intelligent reflector is Therefore, the signal received at the ship is represented as

[0073] y(t)=(h d +h IRS )x(t)+n0;

[0074] Where x(t) represents the transmitted signal, h represents Gaussian white noise. IRS It includes three channels: h1, H2, and h3. Figure 2The intelligent reflector-assisted path mainly consists of three links. The first link is from the transmitter to the intelligent reflector, where the intelligent reflector collects signals from the transmitter's omnidirectional antenna and performs beamforming. The second link is from the base station-side IRS to the waveguide-side IRS (deployment height close to the top height of the waveguide layer). Here, the IRS changes the propagation height of the incident signal, allowing it to propagate near the waveguide layer. The third link is from the intelligent reflector to the receiving antenna. Here, the intelligent reflector changes the propagation angle of the signal, allowing it to be trapped in the waveguide layer for long-distance propagation. Figure 2 As shown, we assume the channel coefficient of the first link is expressed as... The channel coefficient of the second link is At that time, the channel coefficient of the third link is Time-sensitive intelligent reflector channel coefficient h IRS It can be represented as:

[0075]

[0076] in, and This represents a diagonal matrix that reflects the changes in phase and amplitude, α i ∈[0,1] and β i ∈[0,1], representing the coefficient of change of fixed amplitude caused by the i-th phase shift, θ i and This indicates the phase change of the reflected signal.

[0077] Furthermore, in practical applications, the antenna height of the shore-based base station is located within the waveguide layer, such as... Figure 3 As shown, the communication link between the base station and the ship is primarily a single path, where the signal reaches the receiver via a smart reflector-assisted path. In this smart reflector-assisted path, the smart reflector's role is to change the signal propagation angle, allowing the signal to be captured by the waveguide layer. The smart reflector does not need to change the signal propagation altitude because the transmitter's altitude is already within the waveguide layer. Figure 3 As shown, the channel coefficient of the smart reflector is h. IRS Therefore, the signal received at the ship is represented as:

[0078] y(t)=h IRS x(t)+n0;

[0079] Where x(t) represents the transmitted signal, The channel coefficient h of the smart reflector represents Gaussian white noise. IRS The same as above means similar, among which This represents the channel coefficient between the transmitter and the IRS; This represents the channel coefficient between the IRS and the receiver, at which point the radio electromagnetic signal has been trapped in the waveguide layer and propagating.

[0080] The scope of protection of the intelligent reflector-assisted shore-based base station communication method described in this application is not limited to the order of steps listed in this embodiment. Any solution implemented by adding, subtracting, or replacing steps in the prior art based on the principles of this application is included within the scope of protection of this application.

[0081] The application of the intelligent reflector-assisted shore-based base station communication method proposed in this application is the most important protection point of this invention. The transmitting antenna signal mainly reaches the receiving end through two paths: the direct signal-to-receiver path and the waveguide path assisted by the intelligent reflector. First, the parameter information of the transmitting antenna height and antenna downtilt angle of the shore-based base station is obtained. Specifically, this information can be obtained through operators, channel measurement equipment, or simulation platforms, or meteorological data of the corresponding location can be obtained through other means such as the China Meteorological Administration or meteorological stations. Second, the obtained meteorological data is used to calculate the waveguide layer height and waveguide intensity at the corresponding time, and to determine the relationship between the waveguide layer height and the transmitting antenna height. If the transmitting antenna is higher than the waveguide layer (i.e., not located within the waveguide layer), an adjustable-height device such as a drone can be used to carry a smart reflector to the waveguide layer's height. In this case, the waveguide signal trapping angle is calculated based on the waveguide strength. The smart reflector is then used to adjust the signal incident angle and propagation height of the base station signal, allowing for long-distance signal transmission within the waveguide layer. This reduces signal attenuation and enables the signal to propagate a greater distance with lower path loss. If the transmitting antenna is lower than the waveguide layer (i.e., located within the waveguide layer), the waveguide strength needs to be calculated, and the waveguide signal trapping angle calculated accordingly. If the antenna downtilt angle can be adjusted to the waveguide trapping angle, it can be directly adjusted to meet the waveguide trapping requirements. If the antenna downtilt angle is limited by the device itself and cannot be adjusted too significantly, a smart reflector can be used to assist in changing the signal propagation angle to meet the waveguide trapping angle. This invention does not impose specific limitations on various data acquisition and processing methods, or on the devices carrying the smart reflector. This essentially means that transmitting signals from a shore-based base station assisted by a smart reflector into the waveguide layer for long-distance transmission violates the claims of this invention. Furthermore, similarly, this invention does not impose specific limitations on the number of reflecting elements, size, or quantity of the smart reflector. It needs to be emphasized again that the design of these mechanisms has a significant impact on the performance of the communication method of the shore-based base station transmitting device assisted by the smart reflector involved in this invention. This invention does not specify the details of the smart reflector parameters; utilizing the smart reflector to induce signals to enter the waveguide layer for long-distance transmission is the prominent focus of this application.

[0082] This application also provides a smart reflector-assisted shore-based base station communication system. The smart reflector-assisted shore-based base station communication system can implement the smart reflector-assisted shore-based base station communication method described in this application. However, the implementation device of the smart reflector-assisted shore-based base station communication method described in this application includes, but is not limited to, the structure of the smart reflector-assisted shore-based base station communication system listed in this embodiment. All structural modifications and substitutions of the prior art made based on the principles of this application are included within the protection scope of this application.

[0083] See also Figure 5 In one embodiment, this embodiment provides a smart reflector-assisted shore-based base station communication system 50, the system comprising:

[0084] The acquisition module 51 is used to acquire meteorological data of the location of the preset shore-based base station, the height value of the transmitting antenna corresponding to the shore-based base station, and the height range of the waveguide layer at the location of the shore-based base station.

[0085] The judgment module 52 is used to determine whether the height value of the transmitting antenna is within the height value range. If the height value of the transmitting antenna is not within the height value range, the propagation angle and propagation height of the radio electromagnetic wave signal are changed based on a preset intelligent reflective surface. If the height value of the transmitting antenna is within the height value range, the propagation angle of the radio electromagnetic wave signal is changed based on the intelligent reflective surface.

[0086] Since the specific implementation of this embodiment corresponds to the aforementioned method embodiment, the same details will not be repeated here, and those skilled in the art should also understand this.

The memory stores a computer program, and the processor executes the computer program stored in the memory to perform all or part of the steps in the aforementioned method embodiment.

[0089] Electronic device 71; and

[0090] The shore-based base station 72 is communicatively connected to the electronic device, and the shore-based base station transmits radio electromagnetic wave signals to the outside world based on the transmitting antenna;

[0091] The intelligent reflective surface 73 is located on one side of the shore-based base station and is used to change the propagation angle of the radio electromagnetic wave signal so that the radio electromagnetic wave signal propagates within the waveguide layer at the location of the shore-based base station.

[0092] A height-controllable device 74 is fixedly connected to the intelligent reflective surface and is used to adjust the propagation height of the intelligent reflective surface.

[0093] In summary, this application enhances the coverage of shore-based base stations by inducing radio electromagnetic waves to be trapped in the waveguide layer. By using a smart reflector to change the signal propagation angle and by combining a controllable height device with a smart reflector to change the signal propagation height, the signal can propagate in the waveguide layer with low loss, thereby achieving long-distance propagation and ensuring normal communication for ships moving in the open sea.
