[0033] Embodiments of this disclosure are described in detail below, with examples of embodiments illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0034] The current state of mobile network coverage is such that while base station density is high in urban outdoor areas, resulting in good coverage on roads, indoor coverage is poor due to significant signal attenuation. Since 70% of 5G services in residential areas occur indoors, improving indoor coverage in these areas is crucial.

[0035] In residential area coverage, a common approach is to use antennas mounted on opposite rooftops, employing high-power transmission equipment to achieve wide-area coverage. The antennas typically feature a wide vertical beamwidth to ensure coverage of different floors (high, medium, and low), while the horizontal beamwidth is relatively narrow to maximize antenna gain. Current technology commonly uses ±45° dual-polarized antennas to improve anti-interference capabilities between channels. However, as residential buildings become increasingly taller, lower floors experience weaker coverage due to insufficient penetration at large angles of incidence.

[0036] When a linearly polarized signal is incident on glass, part of the wave is reflected back to form a reflected wave, while the other part is projected into a second medium to form a refracted wave. The transmission coefficient of the signal with different polarization directions varies significantly with the incident angle. The transmission coefficient of the polarized signal perpendicular to the incident surface decreases linearly with increasing incident angle, while the transmission coefficient of the polarized signal parallel to the incident surface remains relatively stable at different incident angles. In existing inter-building communication scenarios, the signal of a ±45° dual-polarized antenna can be divided into a polarization component perpendicular to the incident surface and a polarization component parallel to the incident surface. On lower floors, due to the larger incident angle, the loss of the polarization component perpendicular to the incident surface increases, leading to a decrease in communication quality. Since signals with different polarization directions exhibit different penetration loss variations at different incident angles, we can utilize this phenomenon to reduce the impact of penetration loss.

[0037] Therefore, to address the aforementioned issues, this application proposes an inter-building communication antenna coverage system that employs a combination of ±45° dual-polarized antennas and vertically polarized antennas to solve the polarization penetration loss problem between high-rise buildings. Furthermore, the beam coverage areas of the ±45° dual-polarized antennas and vertically polarized antennas differ depending on the building height and distance between buildings, requiring dynamic allocation of their power ratios. To balance communication quality across different floors in residential areas, this proposal provides two power allocation strategies for the polarized antennas based on varying building heights and distances.

[0038] like Figure 1A As shown, the inter-building communication antenna coverage system of this application includes: a reflector, the reflector including multiple antenna elements, the multiple antenna elements including multiple ±45° dual-polarized antenna elements and multiple vertically polarized antenna elements, the multiple ±45° dual-polarized antenna elements being connected to a first port on the reflector, and the multiple vertically polarized antenna elements being connected to a second port on the reflector; a power ratio adjustment module, the power ratio adjustment module including a directional coupler, the first output terminal of the directional coupler being connected to the first port to provide a first power to the multiple ±45° dual-polarized antenna elements, and the second output terminal of the directional coupler being connected to the second port to provide a second power to the multiple vertically polarized antenna elements.

[0039] In other words, the directional coupler of the power ratio adjustment module can output power to the ±45° dual-polarized antenna element and the vertically polarized antenna element respectively. The first power and the second power can be the same or different. That is, the power ratio adjustment module can adjust the power ratio of the ±45° dual-polarized antenna element and the vertically polarized antenna element so that the ±45° dual-polarized antenna element and the vertically polarized antenna element can use different output powers to obtain different gains.

[0040] In some embodiments, the number of antenna elements included in the reflector, the ratio of ±45° dual-polarized antenna elements to vertically polarized antenna elements, etc., can be determined according to the needs of the actual application scenario. The more antenna elements there are, the stronger the signal gain of the building communication antenna coverage system.

[0041] In some embodiments, the power ratio adjustment module further includes: at least one power ratio adjustment unit, wherein each power ratio adjustment unit includes a diode and a capacitor, a first terminal of the at least one power ratio adjustment unit is grounded, and a second terminal of the at least one power ratio adjustment unit is connected to a directional coupler. Figure 1B The diagram shown is a schematic of a power ratio adjustment module, including four power ratio adjustment units, each power ratio adjustment unit consisting of a PIN diode S. i and capacitor C i The composition is as follows: i = 1, 2, 3, 4. Optionally, the number of power ratio adjustment units is not limited to 4; it can be less than 4 or more than 4. For example, when the number of power ratio adjustment units is 4, the ratio of the output power of the two output terminals of the directional coupler chain can be controlled by controlling the conduction and cutoff of 4 diodes. When the number of power ratio adjustment units is 4, the conduction and cutoff of 4 diodes can provide 16 power allocation states. The more power ratio adjustment units there are, the more power allocation states can be provided. Optionally, one power allocation state can correspond to one power ratio, which is the power ratio of the ±45° dual-polarized antenna unit and the vertically polarized antenna unit, that is, the ratio of the first power and the second power. For example, it can be the first power / second power or the second power / first power.

[0042] For example, when there are 4 power ratio adjustment units, 16 power states can be provided. If the diode is on, it represents 1, and off, it represents 0. The 16 states can be represented as 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111. At this time, the power ratio corresponding to each state is determined, and the correspondence between the state and the power ratio is stored. The stored correspondence between the state and the power ratio can be determined according to the total power used in the actual application scenario, the attributes of the directional coupler, the specific implementation method of the power adjustment module, etc.

[0043] Optionally, the inter-building communication antenna coverage system may also include a controller, which can be used to perform calculation and control-related functions, such as calculating the target power ratio, which is the ratio of the first power and the second power determined according to the building spacing, building height, etc. when the inter-building communication antenna coverage system is actually deployed, or calculating the target phase of each antenna element, i.e., the target phase of each antenna element may be different.

[0044] In some embodiments, the power ratio adjustment module further includes: a power ratio control unit, which is connected to the second end of at least one power ratio adjustment unit, and is configured to control at least one power ratio adjustment unit to be turned on or off so that the ratio of the first power and the second power conforms to the target power ratio.

[0045] Optionally, the controller can be connected to the power control unit. The controller can send control commands to the power ratio control unit to instruct the power ratio control unit to control at least one power ratio adjustment unit to be turned on or off. The control commands can be generated based on the target power ratio. That is, after determining the target power ratio, the controller can generate control commands based on the target power ratio. The control commands can control the power ratio control unit to control specific diodes to be turned on or off. For example, after determining the target power ratio, the controller can determine the state of multiple diodes corresponding to the target power ratio, and then instruct the power ratio control unit to control the diodes to be turned on and off in the control commands to meet the state indicated by the control commands, so as to adjust the power ratio.

[0046] Optionally, the power ratio control unit may have multiple output terminals (control terminals), each of which may be connected to the second terminal of a power ratio adjustment unit. For example, when it is necessary to control the conduction of diode 1, current can be output through the output terminal connected to diode 1 to conduct diode 1, or when it is necessary to turn off diode 1, the output current of the corresponding output terminal of diode 1 is stopped.

[0047] In some embodiments, such as Figure 1C As shown, the inter-building communication antenna coverage system further includes: a first phase adjustment module, the receiving end of which is connected to a first port, and at least one output end of which is connected to a plurality of ±45° dual-polarized antenna elements respectively. The first phase adjustment module is configured to adjust the phases of the plurality of ±45° dual-polarized antenna elements to the target phases corresponding to the respective ±45° dual-polarized antenna elements; and a second phase adjustment module, the receiving end of which is connected to a second port, and at least one output end of which is connected to a plurality of vertically polarized antenna elements respectively. The second phase adjustment module is configured to adjust the phases of the plurality of vertically polarized antenna elements to the target phases corresponding to the respective vertically polarized antenna elements.

[0048] Optionally, the controller can also be connected to the receivers of the first phase adjustment module and the second phase adjustment module. The controller can determine the target phase of each antenna element in the current scenario based on the downtilt angle, feed line length, etc., corresponding to each antenna element. Then, the controller generates control commands based on the target phase and sends these commands to the first and / or second phase adjustment modules. The first and / or second phase adjustment modules can then adjust the phases of the multiple ±45° dual-polarized antenna elements to their respective target phases, and / or adjust the phases of the multiple vertically polarized antenna elements to their respective target phases. The controller can also be a control network, control circuit, etc.

[0049] In some embodiments, the plurality of vertically polarized antenna elements include a first portion antenna element and a second portion antenna element, and the plurality of ±45° dual-polarized antenna elements are arranged between the first portion antenna element and the second portion antenna element; or the plurality of vertically polarized antenna elements and the plurality of ±45° dual-polarized antenna elements are arranged in a cross configuration.

[0050] like Figure 1A As shown, multiple ±45° dual-polarized antenna elements are arranged between the first and second part of the antenna elements; that is, multiple ±45° dual-polarized antenna elements can be arranged among multiple vertically polarized antenna elements to separate the multiple vertically polarized antenna elements; or as shown... Figure 1D As shown, multiple vertically polarized antenna elements and multiple ±45° dual-polarized antenna elements can be arranged in a cross configuration.

[0051] This application also proposes a method for inter-building communication antenna coverage, which balances signal coverage between high and low floors through beam allocation and power allocation optimization. This method is applicable to inter-building communication in different scenarios in residential areas.

[0052] Optionally, the inter-building communication antenna coverage method proposed in this disclosure is applicable to the aforementioned inter-building communication antenna coverage system, and the specific content of the method is as follows.

[0053] Figure 2 This is a flowchart illustrating a method for inter-building communication antenna coverage provided in an embodiment of this disclosure. Figure 2 As shown, the method may include the following steps.

[0054] Step 201: Determine the first downtilt angle and the second downtilt angle corresponding to the inter-building communication antenna coverage system on the first building based on the first dielectric constant and the second dielectric constant.

[0055] In some embodiments, the first downtilt angle is the downtilt angle corresponding to the plurality of ±45° dual-polarized antenna elements in the inter-building communication antenna coverage system, the second downtilt angle is the downtilt angle corresponding to the plurality of vertically polarized antenna elements in the inter-building communication antenna coverage system, the first dielectric constant is the dielectric constant corresponding to the light-transmitting element of the second building, and the second dielectric constant is the dielectric constant corresponding to air. The light-transmitting element may, for example, be the glass of the second building.

[0056] In some embodiments, determining the first downtilt angle and the second downtilt angle corresponding to the inter-building communication antenna coverage system on the first building based on the first dielectric constant and the second dielectric constant includes: determining the first incident angle corresponding to a plurality of ±45° dual-polarized antenna elements based on the first dielectric constant, the second dielectric constant and a preset polarization transmission coefficient; determining the second incident angle corresponding to a plurality of vertically polarized antenna elements based on the first incident angle, the height of the second building and the distance between the first building and the second building; and determining the first downtilt angle and the second downtilt angle based on at least one of the first incident angle and the second incident angle.

[0057] In some embodiments, the inter-building communication antenna coverage system can be installed on the roof of the first building, and the transmitting beam of the inter-building communication antenna coverage system can cover the second building. Then, the dielectric constant of the glass of the second building and the dielectric constant of the air can be determined. After that, the preset polarization transmission coefficient can be determined. The preset polarization transmission coefficient can be determined according to actual needs. For example, the preset polarization transmission coefficient can be set to 1 or 0.9, etc. This disclosure does not limit this. Optionally, the first incident angle can be determined according to the formula of the horizontal polarization transmission coefficient and the vertical polarization transmission coefficient. The first incident angle can be the acceptable incident angle of penetration loss corresponding to the ±45° dual-polarized antenna unit. That is, the first incident angle can be the maximum incident angle at which the ±45° dual-polarized antenna unit can penetrate the light-transmitting part of the second building when the height and the distance between the first and second buildings are fixed.

[0058] Optionally, the first dielectric constant can be expressed as τ1, and the second dielectric constant can be expressed as ε2, then the formula for the horizontal polarization transmission coefficient can be expressed as:

[0059]

[0060] Among them, T TE Let θ1 be the horizontal polarization transmission coefficient and θ1 be the first incident angle. The value of the horizontal polarization transmission coefficient can be a preset fixed value. That is, the preset polarization transmission coefficient can include the horizontal polarization transmission coefficient and the vertical polarization transmission coefficient. The first incident angle can be determined according to the above formula.

[0061] The formula for the vertically polarized transmission coefficient can be expressed as:

[0062]

[0063] Among them, T TM θ1 is the vertical polarization transmission coefficient, and θ1 is the first incident angle. Similarly, the value of the vertical polarization transmission coefficient can be a preset fixed value. The first incident angle can be determined according to the above formula. In other words, when preset polarization transmission coefficient, the horizontal polarization transmission coefficient and the vertical polarization transmission coefficient can be preset.

[0064] In some embodiments, after determining the first incident angle, the second incident angle θ2 corresponding to the plurality of vertically polarized antenna elements can be determined based on the first incident angle θ1, the height H of the second building, and the distance L between the first building and the second building. Optionally, the second incident angle can be determined according to the following formula:

[0065] θ2=arctan(H / L)-θ1

[0066] In some embodiments, after determining the first incident angle and the second incident angle, the first downtilt angle θ can be determined based on at least one of the first incident angle and the second incident angle. 1t Second downtilt angle θ 2t Among them, the first downtilt angle θ is determined. 1t Second downtilt angle θ 2t The formula is as follows:

[0067] θ 1t =θ1 / 2

[0068]

[0069] Step 202: Determine the target power ratio based on the first downward tilt angle, the height of the second building, and the distance between the first and second buildings.

[0070] In some embodiments, determining the target power ratio based on the first downtilt angle, the height of the second building, and the distance between the first and second buildings includes: determining the first coverage height corresponding to the plurality of ±45° dual-polarized antenna elements based on the height of the second building and the first downtilt angle; determining the second coverage height corresponding to the plurality of vertically polarized antenna elements based on the height of the second building and the first coverage height; and determining the target power ratio as the ratio of the first coverage height to the second coverage height.

[0071] In some embodiments, based on the height H of the second building and the first downward tilt angle θ 1t The formula for determining the first coverage height h1 corresponding to multiple ±45° dual-polarized antenna elements is as follows:

[0072] h1=Ltanθ1

[0073] Based on the height H of the second building and the first coverage height h1, the formula for determining the second coverage height h2 corresponding to multiple vertically polarized antenna elements is as follows:

[0074] h2=H-Ltanθ1

[0075] The formula for determining the target power ratio η as the ratio of the first coverage height to the second coverage height is as follows:

[0076] η = h1 / h2

[0077] Step 203: Adjust the first power corresponding to the multiple ±45° dual-polarized antenna elements and the second power corresponding to the multiple vertically polarized antenna elements according to the target power ratio.

[0078] In some embodiments, the beam coverage areas of the ±45° dual-polarized antenna and the vertically polarized antenna differ depending on the building height and spacing, and the corresponding power ratio needs to be dynamically allocated. In the scheme disclosed herein, the beam of the ±45° dual-polarized antenna can cover the high-rise area, while the beam of the vertically polarized antenna can cover the low-rise area. The ±45° dual-polarized antenna has a smaller incident angle and shorter path when propagating into the high-rise indoor area, resulting in lower propagation loss. Conversely, the vertically polarized antenna has a larger incident angle and longer path when propagating into the low-rise indoor area, resulting in higher propagation loss. Therefore, a high-gain vertically polarized antenna and a low-gain ±45° dual-polarized antenna are typically used.

[0079] For example, when the area covered by a vertically polarized antenna is large and the propagation distance is long, the power of the vertically polarized antenna is usually greater than that of the ±45° dual-polarized antenna. Adjusting the first power corresponding to multiple ±45° dual-polarized antenna elements and the second power corresponding to multiple vertically polarized antenna elements according to the target power ratio includes: determining a first ratio parameter with the smallest difference from the target power ratio from a set of preset ratio parameters; determining the target state corresponding to at least one power ratio adjustment unit based on the first ratio parameter, where the target state is either on or off; and controlling at least one power ratio adjustment unit to be on or off based on the target state of each unit to adjust the first and second powers.

[0080] The preset ratio parameters can be determined based on the states of the aforementioned diodes. For example, when there are 4 power ratio adjustment units, 16 power states can be provided. If a diode being on represents 1 and being off represents 0, the 16 states can be represented as 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111. In this case, each state can correspond to a preset ratio parameter, which can be a preset power ratio. Optionally, after determining the target power ratio, the target power ratio may not exist among the aforementioned 16 preset ratios. In this case, the preset ratio parameter closest to the target power ratio can be determined, i.e., the first ratio parameter.

[0081] In some embodiments, after determining the first ratio parameter, the state corresponding to the first ratio parameter can be determined. For example, when the state is 1111, it means that all four diodes need to be turned on. At this time, the four diodes can be controlled to be turned on so that the ratio of the first power and the second power output is close to the target power ratio, thereby adjusting the power of the ±45° dual-polarized antenna unit and the vertically polarized antenna unit.

[0082] In summary, the above embodiments of this application can determine the target power ratio based on the first dielectric constant, the second dielectric constant, and building-related information such as building spacing and building height. The state of the diode corresponding to the target power ratio can also be determined. The state of the diode can then be adjusted to achieve the power ratio of the dual-polarized antenna and the vertically polarized antenna. This ensures that the signal quality of the dual-polarized antenna and the vertically polarized antenna is more balanced when the signal propagates indoors, thus avoiding poor signal quality for users on lower floors.

[0083] Figure 3 This is a flowchart illustrating a method for inter-building communication antenna coverage provided in an embodiment of this disclosure. Figure 3 As shown, the method may include the following steps.

[0084] Step 301: Determine the target phase corresponding to each of the multiple antenna elements included in the inter-building communication antenna coverage system on the first building, based on the first downtilt angle and the second downtilt angle.

[0085] In some embodiments, the plurality of antenna elements includes a plurality of ±45° dual-polarized antenna elements and a plurality of vertically polarized antenna elements.

[0086] In some embodiments, the target phase corresponding to each antenna element can be determined according to the downtilt angle of each antenna element, the feed line length of each antenna element, etc. Optionally, antenna elements of the same type have the same downtilt angle, and the feed line length of each antenna element can be the feed line length of the antenna element connected to the first port or the second port, but is not limited thereto.

[0087] Step 302: Adjust the phase of multiple antenna elements to the target phase corresponding to each antenna element, so that the beam of the inter-building communication antenna coverage system covers the second building.

[0088] In some embodiments, after determining the target phase, the phases of multiple antenna elements can be controlled to be adjusted to the target phases corresponding to each antenna element. After the phases of multiple antenna elements are adjusted to the target phases corresponding to each antenna element, the downtilt angles of the multiple antenna elements meet the requirements of the current application scenario, thus enabling the beam of the inter-building communication antenna coverage system to cover the entire second building.

[0089] In summary, the above embodiments of this application can adjust the phase of multiple antenna elements so that the downtilt angle of the multiple antenna elements meets the requirements of the current scenario. This can enable the beam of the inter-building communication antenna coverage system to cover the entire second building. It can solve the problem that when using only ±45° dual-polarized antennas, the polarization component loss perpendicular to the incident surface increases due to the large incident angle on lower floors, resulting in reduced communication quality.

[0090] For the foregoing method embodiments, in order to simplify the description, they are all described as a series of actions. However, those skilled in the art should know that this disclosure is not limited to the described order of actions, because according to this disclosure, some steps may be performed in other orders or simultaneously.

[0091] Secondly, those skilled in the art should also know that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily required by this disclosure.

[0092] The technical solutions of this disclosure will be further described in detail below with reference to specific application embodiments.

[0093] This disclosure provides a building-to-building communication antenna coverage scheme.

[0094] This example method employs a combination of ±45° dual-polarized antennas and vertically polarized antennas on the rooftops of high-rise buildings in residential areas. Through array switching and synthesis of different polarization modes, the ±45° polarized antennas are used in the high-rise areas, while the vertically polarized antennas are used in the low-rise areas. Furthermore, the varying building heights and spacing in residential areas necessitate corresponding adjustments to beam and power distribution. This scheme optimizes beam and power distribution to balance signal coverage across different floors, making it suitable for inter-building communication in various residential scenarios.

[0095] like Figure 4 The diagram shown is a schematic of an inter-building communication scenario proposed in this solution. Based on the dielectric constants of glass and air, this solution obtains the polarization transmission coefficient from air to glass and then back to air, and determines the acceptable incident angle θ1 for penetration loss. The region with an incident angle less than θ1 is the small incident angle region, and the region with an incident angle greater than θ1 is the large incident angle region. Figure 4 To implement an inter-building communication scheme using a combination of two polarized antennas, a dual-polarized antenna and a vertically polarized antenna are installed on the roof of building 1. The beam of the dual-polarized antenna points towards the upper floors (small angle of incidence) of building 2, while the beam of the vertically polarized antenna covers the lower floors (large angle of incidence) of building 2.

[0096] This scheme proposes two beam allocation and power allocation strategies for polarized antennas with different building heights and spacing. The distance between tall building 1 and tall building 2 is L, the building height is H, and the penetration loss is acceptable at the incident angle θ1.

[0097] In the proposed antenna coverage scheme, the beamwidth of the ±45° dual-polarized antenna is θ1, which is a fixed value determined by the dielectric constants of the glass and air. By utilizing the geometry of the inter-building communication scenario, the beamwidth of the vertically polarized antenna can be calculated as θ2 = arctan(H / L) - θ1. Furthermore, the downtilt angle θ of the ±45° dual-polarized antenna... 1t and the downtilt angle θ of the vertically polarized antenna 2t They are respectively:

[0098] θ 1t =θ1 / 2

[0099]

[0100] The ±45° dual-polarized antenna beam and the vertically polarized antenna beam cover different number of layers, and the corresponding power allocation needs to be dynamically allocated according to building height and building spacing. By utilizing the geometry of the inter-building communication scenario, the input power ratio η of the two polarization antennas can be calculated:

[0101] η = h1 / h2

[0102] in,

[0103] h1=Ltanθ1

[0104] h2=H-Ltanθ1

[0105] Assuming the acceptable angle of incidence for the window glass to transmit light is 45°, such as Figure 5 As shown, three typical implementations with different power allocations are presented:

[0106] When the height of the two buildings H = 50m (total 18 floors) and the distance between the buildings L = 40m, according to the above power allocation algorithm, the input power ratio η of the ±45° dual-polarized antenna and the vertically polarized antenna is 4:1, and 20% of users use vertically polarized beam coverage.

[0107] When the height of the two buildings is H = 100m (33 floors in total) and the distance between the buildings is L = 60m, according to the above power allocation algorithm, the input power ratio η of the ±45° dual-polarized antenna and the vertically polarized antenna is 3:2, and 40% of users use vertically polarized beam coverage.

[0108] When the height of the two buildings is H = 100m (33 floors in total) and the distance between the buildings is L = 40m, the input power ratio η of the ±45° dual-polarized antenna and the vertically polarized antenna is 2:3 according to the above power allocation algorithm, and 60% of users use vertically polarized beam coverage.

[0109] The penetration loss is acceptable with a fixed incident angle θ1. As the building spacing and height change, the beamwidth and downtilt angle of the dual-polarized antenna remain constant, while the downtilt angle and beamwidth of the vertically polarized antenna change. Furthermore, the signal propagation paths differ between high and low floors; therefore, when evaluating communication quality, the propagation path loss of electromagnetic waves in free space needs to be considered in the power assessment. The upper vertical angular domain has low path loss, so a low-gain dual-polarized antenna is used; the lower vertical angular domain has high path loss, so a high-gain vertically polarized antenna is used.

[0110] like Figure 1B The diagram illustrates a power ratio adjustment scheme that regulates the output power ratio by controlling the phase. The phase-adjustable π-type phase shifter consists of a transmission line section, four PIN diodes si connected in parallel to ground, and a capacitor Ci, where i = 1, 2, 3, 4. This network can provide 16 power distribution states by controlling the on and off states of the PIN diodes, as shown in the table below. Therefore, the proposed antenna combination scheme based on phase-controlled power ratio can adapt to 16 different application scenarios with varying building-to-building distances.

[0111] state 1 2 3 4 5 6 7 8 S4,3,2,1 0000 0001 0010 0011 0100 0101 0110 0111 state 9 10 11 12 13 14 15 16 S4,3,2,1 1000 1001 1010 1011 1100 1101 1110 1111

[0112] The proposed inter-building communication antenna coverage scheme is designed for different building heights and spacings. It employs a combination of dual-polarized and vertically polarized antennas, and through beamforming and power distribution, achieves uniform coverage across different building levels. The implementation process is as follows: Figure 6 As shown.

[0113] In summary, the above-described examples of this disclosure employ vertically polarized antennas in the large incident angle region, effectively solving the problem of polarization penetration loss and improving signal transmission efficiency; beam distribution is performed separately for high and low floors, which improves the quality of inter-building communication compared to the existing single beam; and power distribution between high and low floors is dynamically adjusted for communication scenarios with different inter-building distances, taking into account the path loss of electromagnetic waves, thereby reducing power waste.

[0114] Figure 7 This is a block diagram of an inter-building communication antenna coverage device 700 provided in an embodiment of this disclosure. Figure 7 As shown, the device 700 includes: a first processing unit 710, used to determine a first downtilt angle and a second downtilt angle corresponding to the inter-building communication antenna coverage system on the first building based on a first dielectric constant and a second dielectric constant, wherein the first downtilt angle is the downtilt angle corresponding to multiple ±45° dual-polarized antenna elements in the inter-building communication antenna coverage system, the second downtilt angle is the downtilt angle corresponding to multiple vertically polarized antenna elements in the inter-building communication antenna coverage system, the first dielectric constant is the dielectric constant corresponding to the light-transmitting element of the second building, and the second dielectric constant is the dielectric constant corresponding to air; a second processing unit 720, used to determine a target power ratio based on the first downtilt angle, the height of the second building, and the distance between the first building and the second building; and a third processing unit 730, used to adjust the first power corresponding to the multiple ±45° dual-polarized antenna elements and the second power corresponding to the multiple vertically polarized antenna elements based on the target power ratio.

[0115] In summary, the device disclosed herein can combine a ±45° dual-polarized antenna unit and a vertically polarized antenna unit to improve coverage in indoor residential areas. Furthermore, by adjusting the antenna power ratio, the antenna gain can be adjusted according to the actual scenario, ensuring signal quality for users in indoor scenarios and improving user experience.
