Description

Reconfigurable intelligent beamforming system
Technical Field
The present disclosure relates generally to the field of wireless communications. The present disclosure relates to reconfigurable intelligent beamforming systems and methods of operation.
Background
High frequency systems, including 5G and 6G mobile systems, utilize high frequency signal spectra, such as millimeter (mm) waves up to THz. High frequency spectrum requires beamforming to overcome link budget problems, reduce scattering and/or have sufficient coverage and mobility. Overcoming the link budget problem includes, but is not limited to, improving one or more of the following: link budget, interference level, coverage and/or system robustness, and multiplexing to have high spectral efficiency.
However, the current solutions for beamforming are too expensive for practical use. For example, an artificial intelligence radio environment may be implemented with a large intelligent surface. These smart surfaces available for high frequency systems are quite large and therefore very expensive.
Disclosure of Invention
Thus, there is a need for a cost effective system that maintains or improves the link budget and/or coverage of a high frequency system.
There is a need for systems and related methods that can alleviate, mitigate or solve the existing disadvantages, such as by providing improved link budget and/or coverage of high frequency systems, while maintaining a reasonable cost.
A reconfigurable intelligent beamforming system is disclosed herein. The reconfigurable intelligent beamforming system includes a passive fixed array panel. The passive fixed array panel is configured to receive a signal. The passive fixed array panel is configured to focus signals to provide focus signals to at least one fixed location. The reconfigurable intelligent beamforming system includes at least one intelligent surface. The at least one smart surface may be located in the at least one fixed location. The at least one smart surface is configured to receive a focus signal. The at least one smart surface is configured to control beamforming of the focused signal to provide a beamformed signal.
An advantage of the present disclosure is to provide improved link budget and coverage for high frequency systems while reducing overall cost. For example, the present invention may provide improved link budget, system robustness, coverage, and multiplexing. The present invention may reduce overall costs by, for example, controlling the process complexity of certain components in the system. Another advantage of the present invention includes increasing signal strength within an indoor area (e.g., a building) that includes surfaces that may reduce or eliminate high frequency signals.

Furthermore, the illustrated examples need not have all of the aspects or advantages shown. Aspects or advantages described in connection with a particular example are not necessarily limited to that example, and may be practiced in any other example, even if not so shown, or if not so explicitly described.
Disclosed herein are systems for beamforming. In particular, reconfigurable intelligent beamforming systems are disclosed herein. The system may utilize a passive fixed array panel and intelligent surface to improve signal coverage and beam forming. The disclosed reconfigurable intelligent beamforming system may provide improved link budget and coverage while maintaining reduced costs. The disclosed reconfigurable intelligent beamforming system may be used for network management.
In one or more example reconfigurable intelligent beamforming systems, the signals disclosed herein may be one or more of the following: energy, transmission, wave energy, 5G signals, 6G signals, sub-6 GHz, electromagnetic energy, waves, electromagnetic plane waves, electromagnetic signals, plane signals, spherical waves, spherical signals, cylindrical waves, and cylindrical signals. As disclosed herein, waves and signals may be used interchangeably. The particular type of signal is not limiting.
In one or more example systems, the signal may be millimeter waves. In one or more example systems, the signal may have a wavelength of 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1mm or less. In one or more example systems, the signal may have a wavelength of 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1mm or more. In one or more example systems, the signal may have a wavelength between 1mm and 10 mm. The particular wavelength of the signal is not limiting.
In one or more example systems, the signal may have a frequency in the range of 1GHz to 100 THz. In one or more example systems, the signal may have a frequency of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 600, 700, 800, 900, or 1000GHz or less. In one or more example systems, the signal may have a frequency of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 600, 700, 800, 900, or 1000GHz or more. In one or more example systems, the signal may have a frequency of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100THz or less. In one or more example systems, the signal may have a frequency of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100THz or more. The particular wavelength of the signal is not limiting.
The disclosed reconfigurable intelligent beamforming system may utilize passive components (e.g., passive fixed array panels) and active components (e.g., intelligent surfaces). The passive components may be passive or semi-passive components.
Once the passive components are set, the passive components may be configured to receive and provide signals without any control capabilities or mechanisms. For example, a passive component may receive a signal and focus the signal in a particular direction to a fixed location. However, passive components may not be able to adjust direction and position from a particular direction and fixed position. Passive components may be static. The passive component may be a semi-passive component. Semi-passive components may be static while maintaining small tunable components.
The active component may be configured to receive and provide signals with control capabilities or control mechanisms. Thus, the active element may be variable, controllable and/or dynamic. For example, the active component may receive a first signal and provide the first signal to a first location in a first direction. Control capabilities or control mechanisms may be used to change one or more directions and positions. Thus, the active component may receive the second signal and provide the second signal to the second location in the second direction. Alternatively, the active component may receive the second signal and provide the second signal in the first direction to a second location different from the first direction. The active component may be configured for, for example, three-dimensional focusing of the signal.
Components of the disclosed reconfigurable intelligent beamforming system, such as active components and passive components, may facilitate reflection and/or steering of signals. As disclosed herein, reflection and orientation may be used interchangeably. Components of the reconfigurable intelligent beamforming system may be used to reflect waves and/or signals in the millimeter wave spectrum. Further, components of the reconfigurable intelligent beamforming system may be configured to reflect signals that occur in phase in a certain direction and/or area.
The user device disclosed herein may be one of many types of electronic devices, such as one or more of the following: user equipment, computers, tablet computers, servers and smart phones. The particular electronic device is not limiting.
Fig. 1 illustrates a wireless communication system. As shown, a wireless communication system may receive a signal 12 from a base station 10. Signals from the base station may be received by the user device 50 and/or one or more large intelligent surfaces 14. The large intelligent surface 14 may reflect the signal as a reflected signal 16 towards the user device 50.
However, in order to properly provide signals 12 from base station 10 to user device 50, intelligent surface 14 needs to be large enough to collect diffuse signals from base station 10 to direct them to user device 50 for adequate coverage. Since the user device 50 may be mobile, such as a cellular telephone, the smart surface 14 needs to be configurable, such as active and/or controllable, in order to properly direct the reflected signal 16. While there are a variety of methods for controlling the intelligent surface 14, they quickly become cost prohibitive in the size required to properly provide the signal to the user device 50. Furthermore, a large number of antenna elements (e.g., greater than a threshold) are required to provide adequate signal coverage.
A base station may be considered a radio access network node, e.g. an eNodeB and/or a gNB. The terms "base station" and "radio access network node" may be used interchangeably in this disclosure.
Fig. 2 shows a schematic diagram illustrating an example reconfigurable intelligent beamforming system 100 and base station 10 and user equipment 50 according to the present disclosure. The disclosed reconfigurable intelligent beamforming system 100 may greatly reduce cost while providing adequate signal coverage. Reconfigurable intelligent beamforming system 100 may provide improved link budget and coverage for high frequency systems. The reconfigurable intelligent beamforming system 100 may also provide adequate signal coverage indoors and/or outdoors.
As shown, the reconfigurable intelligent beamforming system 100 includes a passive fixed array panel 102. The passive fixed array panel 102 is configured to receive a signal 104. The passive fixed array panel 102 is configured as a focus signal to provide a focus signal 106 to at least one fixed location. The reconfigurable intelligent beamforming system 100 also includes at least one intelligent surface 108 at least one fixed location. The at least one smart surface 108 is configured to receive the focus signal 106. The at least one smart surface 108 is configured to control the beamforming of the focused signal 106 to provide a beamformed signal 110.
In one or more example systems, the reconfigurable intelligent beamforming system 100 may include one or more passive fixed array panels 102. The passive fixed array panel 102 may be considered a passive component of the reconfigurable intelligent beamforming system 100. The passive fixed array panel 102 is particularly advantageous for directing signals to areas with certain signal obstructions, such as within a building.
The reconfigurable intelligent beamforming system 100 may include a plurality of passive fixed array panels 102. One or more of the plurality of passive fixed array panels 102 may be physically connected to another. One or more of the plurality of passive-fixed array panels 102 may be spaced apart from the second passive-fixed array panel 102.
The passive fixed array panel 102 may not include any controllable features, thereby rendering the fixed array panel passive and fixed. The passive fixed array panel 102 may be or may include a passive radio repeater. The passive fixed array panel 102 may be configured to be positioned in 1, 2, or 3 positions, e.g., states.
As disclosed herein, the passive-fixed-array panel 102 may include one or more arrays, such as passive-fixed arrays. Each passive fixed array panel 102 may include 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 passive fixed arrays. Each passive fixed array panel 102 may include greater than 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 passive fixed arrays. Each passive fixed array panel 102 may include fewer than 2, 3, 4, 5, 6, 7, 8, 9, or 10 passive fixed arrays. The passive fixed array panel 102 may include one or more printed circuit boards.
In one or more example systems, the passive fixed array panel 102 may be configured to receive (e.g., collect) the incoming signals 102. For example, the passive fixed array panel 102 may be configured to receive signals 102 from one or more of: user equipment 50, base station 10, and intermediate components. The passive fixed array panel 102 may include components, such as electronic components, configured to process signals and/or output signals. For example, the passive fixed array panel 102 may be configured to output a focus signal 106.
In one or more example systems, one or more passive fixed arrays on the passive fixed array panel 102 may be configured to focus the signal 104 into a focused signal 106 in a fixed direction (e.g., a first direction). This is advantageous when the signal 104 is of low density. In one or more example systems, one or more passive fixed arrays on the passive fixed array panel 102 may be configured to focus the signal 104 to a fixed location (e.g., a first location) as the focus signal 106. One or more passive fixed arrays on the passive fixed array panel 102 may be configured to focus the signal 104 into a focused signal 106 in a second fixed direction. One or more passive fixed arrays on the passive fixed array panel 102 may be configured to focus the signal 104 at a second fixed location as a focused signal 106.
In one or more example systems, most (e.g., all) of the passive fixed arrays on the passive fixed array panel 102 can be configured to focus the signal 104 to the same fixed location as the focus signal 106. In one or more example systems, the passive fixed array on the passive fixed array panel 102 may be configured to focus the signal 104 to a different fixed location as a focused signal 106. For example, the passive fixed array panel 102 may be configured to focus the signal 104 to 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 different fixed locations as the focus signal 106.
The passive fixed array panel 102 may be configured to receive (e.g., collect) an input signal 104 and focus the signal into a focus signal 106. For example, the passive-fixed-array panel 102 may provide the focus signal 106 to a fixed location, such as where the at least one smart surface 108 is located. As used herein, focusing a signal may include receiving a signal and focusing the signal to, for example, a fixed location. As used herein, focusing may include receiving a wide low density signal and concentrating the signal. The low density signal may occur as the signal power density decreases away from the base station 10 because the signal power density may decrease based on distance from the source. Focusing may include focusing and/or steering to a fixed location, e.g., to provide a higher power density than has been received. Focusing may include outputting the signal at a specific non-destructive stage. For example, the passive fixed array panel 102 may receive low density signals from the base station 10 and provide a focus signal 106 to meet at a single fixed location. The passive fixed array panel 102 may be configured to enhance signal and focus. In one or more example systems, the passive fixed array panel 102 may be configured to transmit a focus signal 106.
As shown in fig. 2, the passive fixed array panel 102 may be configured to be reflective. In one or more example systems, the passive fixed array panel 102 may be a passive fixed reflective array panel. The passive fixed array panel 102 may be configured to receive the signal 104 and provide a reflected focus signal 106. For example, the passive fixed array panel 102 may be configured to receive the signal 104 on a first side (e.g., a first surface) of the passive fixed array panel 102. The passive-fixed-array panel 102 may then provide the focus signal 106 from the same first side (e.g., first surface). The passive fixed array panel 102 may be opaque.
In one or more example systems, the passive fixed array panel 102 may be planar. In one or more example systems, the passive fixed array panel 102 may be a curved passive fixed array panel. In one or more example systems, the passive fixed array panel 102 may be angled. In one or more example systems, the passive fixed array panel 102 may be one or more of the following: curved, angled, and flat.
In one or more example systems, the passive fixed array panel 102 does not include metamaterials. In one or more example systems, the passive fixed array panel 102 does include metamaterials. In one or more example systems, the passive fixed array panel 102 may include some passive fixed array panels that include metamaterials and some passive fixed array panels that do not include metamaterials.
The particular size of the passive fixed array panel 102 is not limiting. The dimensions may vary depending on the wavelength of the signal. The passive fixed array panel 102 may be configured to receive signals from a range of wavelengths, such as 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100 different wavelengths.
In one or more example systems, the passive fixed array panel 102 may have a height of 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 m. In one or more example systems, the passive fixed array panel 102 may have a height of greater than 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 m. In one or more example systems, the passive fixed array panel 102 may have a height of less than 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 m.
In one or more example systems, the passive fixed array panel 102 may have a width of 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 m. In one or more example systems, the passive fixed array panel 102 may have a width greater than 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 m. In one or more example systems, the passive fixed array panel 102 may have a width of less than 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 m.
In one or more example systems, the reconfigurable intelligent beamforming system 100 may also include at least one intelligent surface 108. For example, reconfigurable intelligent beamforming system 100 may include 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 intelligent surfaces 108. The at least one smart surface 108 may be located at a fixed location where the focus signal 106 is focused.
As disclosed herein, at least one smart surface (IS) 108 may also be named Reconfigurable Reflective Device (RRD), reconfigurable smart surface (RIS), reflective Antenna (RA), controllable element surface, reflective antenna array, and smart reflective surface (IRS). The at least one intelligent surface 108 may be "intelligent" in that it may be controllable, for example, by a user device and/or a base station. For example, the at least one smart surface 108 can dynamically modify its frequency and/or radiation characteristics, e.g., in a controlled and/or reversible manner. The at least one smart surface 108 may be dynamically controlled. In one or more example systems, the at least one smart surface 108 may be an active device. As disclosed herein, at least one intelligent surface 108 may be considered an active component of the reconfigurable intelligent beamforming system 100. In other words, at least one smart surface 108 may be an active smart surface.
The smart surface 108 may be used to direct signals to a particular location or a particular direction. For example, at least one smart surface 108 may be used to direct a signal, such as the focus signal 106, to a location or direction where the user device 50 or a user device, such as a receiver device, may be located. This may improve reception at the user equipment 50 and avoid dead or dead zones where signals do not arrive. The at least one intelligent surface 108 may be particularly advantageous for directing signals to areas (e.g., within a building) that have certain waves and/or signal obstructions. The at least one intelligent surface 108 may be part of a repeater system, such as part of an intelligent repeater system.
The at least one smart surface 108 is configured to receive (e.g., collect) the focus signal 106 from the passive fixed array panel 102. The at least one smart surface 108 may be configured to control the beamforming of the focus signal 106. The at least one smart surface 108 may be configured to provide a beamformed signal 110. For example, as shown in fig. 2, the at least one intelligent surface 108 may be configured to provide a beamformed signal 110 to the user device 50.
The at least one smart surface 108 may be configured to control beamforming. Beamforming may be regarded as spatial filtering, e.g. modifying the direction or directionality of a signal to enable directional signal transmission. In other words, controlling beamforming may be considered to control and/or apply spatial filters, and/or control the direction or directionality of signals to achieve a particular directional signal transmission. The at least one smart surface 108 itself may control the beamforming. A network associated with the at least one smart surface 108 may control beamforming. A sensor such as a radio frequency sensor may control the beamforming. Adaptive beamforming may be used with at least one smart surface 108.
In one or more example systems, at least one smart surface 108 may be configured to provide a beamformed signal 110 to a particular device, such as user device 50.
