It is becoming possible to obtain high-quality communication services in high-speed moving means such as automobiles and trains. However, in air-to-air coverage wireless communication systems, communication signals are often transmitted using Line Of Sight (LOS) distances, and due to the lack of reflectors, it is difficult for the wireless channels in these systems to support two or more multi-streamings. As a result, the throughput of a single terminal in air-to-air coverage wireless communication networks is small, and passengers on aircraft cannot obtain high-quality communication services, resulting in a poor user experience.

[0013] In order to make the objectives, technical solutions and advantages of the present application clearer, the following detailed description will be given of the embodiments of the present application with reference to the accompanying drawings, in which the embodiments and features of the embodiments of the present application can be arbitrarily combined unless contradictory.

[0014] 1 is a schematic diagram of the configuration and structure of a ground-to-air wireless communication system of the present application. As shown in FIG. 1, the ground-to-air (ATG) wireless communication system includes a core network device 101, an Internet device 102, a base station 104, and an on-board terminal 103.

[0015] Here, the base station 104 is a ground base station, and the on-board terminal 103 is a terminal mounted on an aircraft. The base station 104 needs to communicate not only with the on-board terminal 103, but also with smart terminals (e.g., smartphones, tablets, etc.) used by passengers on the aircraft.

[0016] When the base station 104 communicates with the smart terminals used by the passengers of the aircraft, it communicates with the smart terminals used by the passengers of the aircraft through an on-board mobile hotspot (Wi-Fi) device installed in the aircraft, and the on-board Wi-Fi device needs a bearer, and the communication pressure is excessively large. In addition, the speed of the aircraft can reach 800 to 1200 km / h, which is a very high-speed means of transportation, and the passengers of the aircraft cannot obtain good quality communication services.

[0017] In a situation where multiple passengers on an aircraft use mobile data to download or upload, each passenger cannot obtain the desired bandwidth resource. In order to meet the bandwidth needs of each passenger, it is necessary to increase the bandwidth of the ATG wireless communication system or use multi-streaming between the on-board terminal 103 and the base station 104 as much as possible. However, bandwidth resources are extremely valuable and cannot be used in their entirety for a dedicated network system such as the ATG wireless communication system. In addition, communication signals are often transmitted between the on-board terminal 103 and the base station 104 using a line of sight (LOS) distance. Here, the LOS distance means that there is a clear and unobstructed communication channel between the on-board terminal 103 and the base station 104, and the on-board terminal 103 can directly receive the communication signal transmitted from the base station 104. Due to the peculiarities of the communication channel corresponding to this LOS distance, the communication channel based on the LOS distance cannot support multi-streaming. In an environment such as air cover where the LOS distance is dominant, how to increase the number of data streams and the data rate of individual users is an issue that needs to be resolved immediately.

[0018] A first aspect of the present application provides an information transmission method. Figure 2 is a flowchart of the information transmission method provided by the present application. This information transmission method can be applied to a reflection device. As shown in Figure 2, the information transmission method of the present application may include the following steps S201 and S202.

[0019] In step S201, communication information transmitted from a base station is obtained.

[0020] Here, the communication information is carried using a communication signal, and the communication information includes one or more of broadcast information, channel state information, downlink control information, and downlink traffic information.

[0021] It should be noted that the reflecting device may be an active device or a passive device. If it is determined that the reflecting device is an active device, the active reflecting device may adjust the angle of the beam corresponding to the target transmission channel between the reflecting device and the on-board terminal according to the control information sent from the base station, so that the target transmission channel can more accurately transmit communication information to the on-board terminal.

[0022] If it is determined that the reflector is a passive device, the passive reflector cannot automatically adjust the reflection weight between the passive reflector and the on-board terminal. When the passive reflector is mounted, the mounting position of the passive reflector is a position determined by a preset network planning parameter, and the mounting position includes one or more of mounting angle information, mounting height information, and distance information between the passive reflector and the base station. Note that the passive reflector is a device that is provided for a special purpose and configured to reflect a communication signal to the on-board terminal, and is not a general obstacle.

[0023] Here, the passive reflector may increase the probability that the on-board terminal receives the communication information by using a beam having a beam width equal to or greater than a preset width threshold (i.e., a wide beam). The beam width includes a horizontal beam width and / or a vertical beam width. The preset width threshold includes a half power beam width (HPBW).

[0024] In step S202, based on the reflection weight of the reflecting device, the communication signal is reflected to the on-board terminal by a beam corresponding to the reflection weight.

[0025] In this specification, "reflecting a communication signal to an onboard terminal by a beam corresponding to a reflection weight" means carrying a communication signal by a beam corresponding to the reflection weight and reflecting the beam carrying the communication signal to the onboard terminal.

[0026] Here, in order to make the direction of the beam corresponding to the communication signal reflected to the on-board terminal more accurate, the reflection weight of the reflecting device may be self-adaptively adjusted. This reflection weight may be the reflection angle of the reflecting device, or the beam width corresponding to the reflected signal, etc. The above is merely an example of the reflection weight, which may be specifically set according to the specific implementation, and other reflection weights not described are also within the scope of protection of the present application, and will not be described here.

[0027] In the present application, a communication signal carrying communication information is transmitted to a reflector, and based on the reflection weight of the reflector, the reflector reflects the communication signal to the on-board terminal by a beam corresponding to the reflection weight, thereby ensuring that the communication information transmitted through the target transmission channel reaches the on-board terminal smoothly, and improving the quality of the air-to-air coverage channel. By adding a reflector in addition to the transmission channel of the conventional base station and the on-board terminal, the communication path between the base station and the on-board terminal is increased, and the number of simultaneous data streams transmitted from the base station to the on-board terminal is increased, thereby enabling the air-to-air coverage wireless communication system to support multi-streaming, and improving the communication rate of the terminal.

[0028] 3 is a flowchart of an information transmission method provided by the present application. The information transmission method can be applied to a reflection device. As shown in FIG. 3, the information transmission method of the present application may include the following steps S301 to S304.

[0029] In step S301, communication information transmitted from a base station is obtained.

[0030] In one exemplary embodiment, communication information transmitted from a base station is obtained via a first transmission channel and / or a second transmission channel, where the first transmission channel is a line-of-sight transmission channel between the reflector device and the base station, and the second transmission channel is a non-line-of-sight transmission channel between the reflector device and the base station.

[0031] The non-line-of-sight distance transmission channel is a transmission channel that is determined based on a no line-of-sight (NLOS) distance. The line-of-sight distance transmission channel is a transmission channel that is determined based on a LOS distance.

[0032] For example, there are multiple reflecting devices (e.g., a first reflecting device and a second reflecting device) between the on-board terminal and the base station, and these reflecting devices block communication signals between the on-board terminal and the base station. The communication information transmitted from the base station may reach the second reflecting device directly via the first transmission channel, or may reach the second reflecting device via the second transmission channel (e.g., the communication information transmitted from the base station is forwarded by the first reflecting device and the second reflecting device acquires the communication information), thereby allowing the current device (i.e., the second reflecting device) to acquire the communication information transmitted from the base station via multiple transmission channels, and the number of simultaneous data streams transmitted from the base station to the current device can be increased, and the communication quality of the current device can be improved.

[0033] In step S302, control information transmitted from the base station is obtained.

[0034] Here, the control information includes adjustment information for the angular magnitude and / or the direction of the beam corresponding to the target transmission channel.

[0035] In one exemplary embodiment, the reflector device includes a Reconfigurable Intelligent Surface (RIS) device that automatically adjusts the angle of a beam corresponding to a target transmission channel between the on-board terminal based on acquired control information.

[0036] In step S303, the reflection weight of the beam corresponding to the target transmission channel is adjusted based on the control information.

[0037] In an exemplary embodiment, there are multiple transmission channels between the reflector and the on-board terminal, and a target transmission channel is selected from the multiple transmission channels as the transmission channel for communication information. By using the target transmission channel as the transmission channel for communication information, the communication information transmitted to the on-board terminal can be more accurate.

[0038] The RIS device may increase or decrease the magnitude of the reflection weight of the beam corresponding to the target transmission channel between the on-board terminal according to the angle magnitude adjustment information, and may adjust the horizontal and / or vertical direction of the beam corresponding to the target transmission channel according to the direction adjustment information of the beam corresponding to the target transmission channel. Furthermore, the RIS device may simultaneously adjust the direction of the beam corresponding to the target transmission channel and the angle magnitude of the beam corresponding to the target transmission channel according to the control information. This allows the beam corresponding to the target transmission channel to be focused on the on-board terminal, and ensures the accuracy of the target transmission channel.

[0039] Note that the above is merely an explanation of examples of control information, and other control information not described is also within the scope of protection of the present application and can be specifically set according to specific situations, so that the explanation will be omitted here.

[0040] In step S304, based on the reflection weight of the reflecting device, the communication signal is reflected to the on-board terminal by a beam corresponding to the reflection weight.

[0041] In addition, the transmission channel between the conventional base station and the on-board terminal is a corresponding transmission channel based on LOS distance, and by adding a corresponding transmission channel in addition to the conventional corresponding transmission channel based on LOS distance, the transmission channel between the base station and the on-board terminal can be made richer, and the number of simultaneous data streams transmitted from the base station to the on-board terminal can be increased. This allows the on-board terminal to receive communication information transmitted from the base station through multiple different transmission channels, improving the signal quality of the on-board terminal and ensuring the completeness and accuracy of the communication information received by the on-board terminal.

[0042] In the present application, the communication information transmitted from the base station is obtained through the first transmission channel and / or the second transmission channel, i.e., the communication information transmitted from the base station is obtained through multiple transmission channels, so that the number of simultaneous data streams transmitted from the base station to the current device can be increased, and the communication quality of the current device can be improved. In addition, the control information is obtained through the first transmission channel (i.e., the line-of-sight transmission channel between the current device and the base station), so that the accuracy of the control information can be ensured. The reflection weight is adjusted using the control information, so that the communication information transmitted through the target transmission channel can be ensured to reach the onboard terminal smoothly, and the quality of the channel covering the airspace is improved.

[0043] In one exemplary embodiment, the method further includes obtaining position information of the reflecting device and position information of the onboard terminal before adjusting the reflection weight of the beam corresponding to the target transmission channel based on the control information, and determining the control information based on the position information of the onboard terminal and the position information of the reflecting device.

[0044] Here, the position information of the on-board terminal may be longitude and latitude information, and the position information of the current device may also be longitude and latitude information, and the relative position between the on-board terminal and the current device can be accurately calculated using the longitude and latitude information, and control information can be determined based on this relative position.

[0045] By determining the location information of a specific on-board terminal and the location information of the current device through the latitude and longitude information, the accuracy of the location information of each device is improved, and the accuracy of the control information is improved.

[0046] In one exemplary embodiment, the reflecting device includes a plurality of used reflecting units, and determining the control information based on the position information of the onboard terminal and the position information of the reflecting device includes selecting a target reflecting unit from the plurality of used reflecting units based on the position information of the onboard terminal and the position information of the reflecting device, determining a reflection weight corresponding to the target reflecting unit, and determining the control information based on the reflection weight corresponding to the target reflecting unit.

[0047] Here, each of the reflection units used may be a low-cost passive reflection element or an active reflection element, and different reflection elements correspond to different reflection weights.

[0048] According to the position information of the on-board terminal and the position information of the current device, a specific orientation of the on-board terminal relative to the reflecting device (e.g., relative position information (e.g., amplitude information) and / or relative angle information (e.g., phase information), etc.) can be determined, and based on this specific orientation, it can be determined whether a certain reflecting unit is suitable for use as a target reflecting unit. The target reflecting unit needs to satisfy a preset reflection condition (e.g., whether the reflection angle of the target reflecting unit satisfies the relative angle information of the on-board terminal relative to the reflecting device, and / or whether the position of the target reflecting unit is more suitable for transmitting a reflected signal to the on-board terminal, etc.).

[0049] Furthermore, the target reflection unit may be multiple, and determining the control information based on the reflection weight corresponding to the target reflection unit (or the reflection weight of the target reflection unit) includes sorting the multiple target reflection units based on the reflection weights corresponding to the multiple target reflection units to obtain a sorting result (for example, the target reflection unit with the largest reflection weight gain is set as the final target reflection unit), and determining the control information based on the reflection weight corresponding to this final target reflection unit. By setting the one target reflection unit with the largest reflection weight gain as the final target reflection unit, the accuracy of the control information can be improved.

[0050] By determining control information based on information of reflection weights (e.g., amplitude information and / or phase information) corresponding to different reflection units and realizing a target transmission channel by having multiple reflection units cooperate with each other, the target transmission channel can be adjusted, and the performance of the wireless communication network is significantly improved.

[0051] In one exemplary embodiment, the target transmission channel is a channel corresponding to a beam based on an augmented or null steering signal, where the null steering signal is a signal that amplifies the desired signal, suppresses the interference signal, and aligns the main lobe of the beam with the direction of incidence of the desired signal as much as possible, and the null steering signal can obtain the lowest gain point in the beam direction diagram, ensure the accuracy of the beam, and improve the accuracy of the target transmission channel.

[0052] In one exemplary embodiment, the method further includes reflecting a communication signal to the onboard terminal with a beam corresponding to the reflection weight based on a reflection weight of the reflecting device, and then reflecting a beam corresponding to a response signal transmitted from the onboard terminal to the base station.

[0053] Here, the response signal carries a response message, which is information fed back from the on-board terminal regarding the communication information.

[0054] By reflecting a beam corresponding to (carrying) a response signal transmitted from an onboard terminal back to the base station, the base station can accurately acquire the response information fed back from the onboard terminal, thereby ensuring normal communication.

[0055] A second aspect of the present application provides an information transmission method. Figure 4 is a flowchart of the information transmission method provided by the present application. This information transmission method can be applied to a base station. As shown in Figure 4, the information transmission method of the present application may include the following steps S401 and S402. In step S401, a communication signal is used to carry communication information.

[0056] Here, the control information is information configured to adjust the reflection weight of a beam corresponding to a target transmission channel, where the target transmission channel is a transmission channel between the reflecting device and the on-board terminal. In step S402, a communication signal is transmitted to the reflecting device.

[0057] When the reflecting device determines that it has received the communication signal, it reflects the communication signal to the on-board terminal by a beam corresponding to the reflection weight based on the reflection weight of the reflecting device, where the reflection weight is the reflection weight of the beam corresponding to the target transmission channel, and the target transmission channel is the transmission channel between the reflecting device and the on-board terminal.

[0058] In an exemplary embodiment, the method further includes obtaining control information prior to transmitting the communication signal to the reflector device, the control information configured to adjust a reflection weight of a beam corresponding to a target transmission channel, the target transmission channel being a transmission channel between the reflector device and an on-board terminal, and transmitting the control information to the reflector device.

[0059] Here, the reflecting device adjusts the reflection weight of the beam corresponding to the target transmission channel between the on-board terminal based on the control information, ensuring that the angle of the beam corresponding to the target transmission channel meets the transmission needs (e.g., accurately matching the angle of the beam corresponding to the target transmission channel to the on-board terminal so that the communication information transmitted from the reflecting device is accurately received by the on-board terminal), thereby improving the transmission accuracy of the communication information.

[0060] In the present application, the obtained control information and communication information are transmitted to the reflector, and the reflector adjusts the reflection weight of the beam corresponding to the target transmission channel based on the control information, so that the reflector transmits the communication information to the on-board terminal quickly and accurately using the target transmission channel, thereby ensuring that the on-board terminal receives the communication information accurately. A reflector is added between the base station and the on-board terminal, and the addition of the reflector increases the communication paths between the base station and the on-board terminal, thereby increasing the number of simultaneous data streams transmitted from the base station to the on-board terminal, which enables the air-to-air coverage wireless communication system to support multi-streaming, and improves the communication rate of the terminal.

[0061] In some exemplary embodiments, obtaining the control information includes obtaining position information of the reflecting device and position information of the onboard terminal, and determining the control information based on the position information of the onboard terminal and the position information of the reflecting device.

[0062] Here, the position information of the on-board terminal and the position information of the reflecting device can be indicated using longitude and latitude information, accurately representing the relative position between the on-board terminal and the reflecting device, and further, control information can be determined based on this relative position, ensuring that the reflecting device accurately adjusts the target transmission channel between the on-board terminal and the reflecting device based on this control information, thereby improving the accuracy of the transmission of communication information.

[0063] In some exemplary embodiments, the method further includes obtaining base station location information before transmitting the control information to the reflecting device, and determining an angle of a beam corresponding to the first transmission channel based on the base station location information and the reflecting device location information.

[0064] Here, the first transmission channel is a line-of-sight transmission channel between the reflector and the base station, which ensures that the reflector can more easily and accurately obtain the control information sent from the base station, and ensures the accuracy of the control information.

[0065] It should be noted that the line-of-sight transmission channel is a transmission channel determined based on the LOS distance. The base station can transmit communication information or control information to the reflector accurately and without error through the first transmission channel, so that the reflector can adjust the angle of the beam corresponding to the target transmission channel between the base station and the on-board terminal based on the control information, thereby realizing the accurate control of the reflector by the base station.

[0066] In some example embodiments, the first transmission channel includes a transmission channel based on channel state information and / or a transmission channel based on synchronization signals and PBCH blocks.

[0067] Here, the synchronization signal and PBCH block (SSB) includes primary synchronization signals (PSS), secondary synchronization signals (SSS) and physical broadcast channels (PBCH), among which, the PSS or SSS can be flexibly arranged at any position of the carrier, not at the bin of the center frequency of the carrier, to realize flexible arrangement of the carrier.

[0068] Here, the channel state information is used to represent the channel attributes of the communication link. The channel state information includes the attenuation coefficient of the communication signal in each transmission channel. The base station can enable the terminal to obtain a more accurate channel estimation by using a Channel State Information-Reference Signal (CSI-RS) port of the channel state information and a reflector to which the transmission beam is directed.

[0069] In some exemplary embodiments, the target transmission channel includes a channel determined based on a first beam of the onboard terminal or a channel determined based on a second beam of the onboard terminal, where the beamwidth of the first beam is smaller than the beamwidth of the second beam.

[0070] Here, the beamwidth includes a horizontal beamwidth and / or a vertical beamwidth, and the preset width threshold includes a half-power beamwidth.

[0071] By setting a channel determined based on a first beam of the onboard terminal or a channel determined based on a second beam of the onboard terminal as a target transmission channel and transmitting communication information between the onboard terminal and the base station using this target transmission channel, the number of simultaneous data streams between the onboard terminal and the base station is increased, thereby enabling the air-to-air coverage wireless communication system to support multi-streaming and improving the communication rate of the terminal.

[0072] In some exemplary embodiments, the method further includes, after transmitting the control information to the reflecting device, if the target transmission channel is determined to be the determined channel based on the second beam of the on-board terminal, processing the information transmitted by the target transmission channel using a maximum ratio combining method to obtain response information, where the response information is response information forwarded by the reflecting device and fed back by the on-board terminal on the communication information.

[0073] Here, in the maximum ratio combining method, the base station determines a weight corresponding to each received signal based on the strength of the received signal, and performs weighted combining processing on each received signal to make the processed received signal clearer, thereby ensuring that more complete response information can be obtained through the processed received signal.

[0074] For example, the second beam may be a beam corresponding to an omnidirectional antenna, and the radiated energy of the omnidirectional antenna may affect not only the LOS distance between the on-board terminal and the base station, but also the NLOS distance between the on-board terminal and other reflectors. In this case, the base station processes the information transmitted by the target transmission channel according to the magnitude of the reflected energy corresponding to each reflector using a maximum ratio combining method, so that the response information transmitted and obtained from the on-board terminal can be more complete.

[0075] The third aspect of the present application provides a reflecting device. Figure 5 is a configuration block diagram of the reflecting device provided by the present application. As shown in Figure 5, the reflecting device includes a first acquisition module 501 configured to acquire communication information transmitted from a base station and carried using a communication signal, and a reflection module 502 configured to reflect the communication signal to an on-board terminal by a beam corresponding to the reflection weight based on the reflection weight of the reflecting device.

[0076] In the present application, the control information and communication information transmitted from the base station are acquired by the first acquisition module, and the adjustment module is used to adjust the angle of the beam corresponding to the target transmission channel based on the control information, thereby ensuring that the communication information transmitted through the target transmission channel reaches the on-board terminal smoothly, and improving the quality of the channel covering the airspace. The communication information is transmitted to the on-board terminal through the target transmission channel by the first transmission module, and the target transmission channel is added in addition to the conventional transmission channel between the base station and the on-board terminal, thereby increasing the number of simultaneous data streams transmitted from the base station to the on-board terminal, thereby enabling the airspace coverage wireless communication system to support multi-streaming, and improving the communication rate of the terminal.

[0077] A fourth aspect of the present application provides a base station. Figure 6 is a configuration block diagram of the base station provided by the present application. As shown in Figure 6, the base station includes a transport module 601 configured to transport communication information using a communication signal, and a transmission module 602 configured to transmit the communication signal to a reflector, so that the reflector reflects the communication signal to an onboard terminal by a beam corresponding to the reflection weight based on the reflection weight of the reflector.

[0078] In the present application, after the second acquisition module acquires the control information for adjusting the angle of the beam corresponding to the target transmission channel and the communication information, the second transmission module transmits the control information and the communication information to the reflector, so that the transmission channel between the reflector and the on-board terminal is more accurate, and the communication information transmitted through the target transmission channel is guaranteed to reach the on-board terminal smoothly, and the quality of the air coverage channel is improved. By adding the target transmission channel in addition to the conventional transmission channel between the base station and the on-board terminal, the number of simultaneous data streams transmitted from the base station to the on-board terminal is increased, which enables the air coverage wireless communication system to support multi-streaming, and improves the communication rate of the terminal.

[0079] The fifth aspect of the present application provides an information transmission system. Figure 7 is a configuration block diagram of the information transmission system provided by the present application. As shown in Figure 7, the information transmission system includes a reflecting device 710 configured to execute the information transmission method of the first aspect, a base station 720 configured to execute the information transmission method of the second aspect, and an on-board terminal 730 configured to obtain communication information transmitted from the base station 720, generate response information based on the communication information, transmit the response information to the reflecting device 710 using a target transmission channel, and cause the reflecting device 710 to transmit the response information to the base station 720.

[0080] Here, the reflecting device may be an active device configured to perform the information transmission method of the first aspect, or a passive device that forwards the received communication information transmitted from the base station 720 to the on-board terminal 730 by different reflection weights. The on-board terminal 730 may be a terminal supported by an aircraft, a drone or other airborne cover system. The base station 720 may be a terrestrial base station.

[0081] The base station 720 transmits control information to the reflector 710 via a port corresponding to the CSI-RS, thereby making the reflector 710 adjust the angle of the beam directed to the reflector 710 based on the control information, and accurately transfers the communication information transmitted from the base station from the reflector 710 to the onboard terminal 730. It is ensured that the onboard terminal 730 obtains information such as more accurate channel estimation, a Channel Quality Indicator (CQI), a Rank Indication (RI), and a Precoding Matrix Indicator (PMI).

[0082] Here, the CQI is used to evaluate and reflect the channel quality of the Physical Downlink Shared Channel (PDSCH). For example, 0 to 15 are used to indicate the channel quality of the PDSCH. 0 indicates the worst channel quality, and 15 indicates the best channel quality. If the channel quality of the PDSCH is good, the base station 720 can transmit more data to the onboard terminal 730. If the channel quality of the PDSCH is bad, the base station 720 can only transmit a part of the data to the onboard terminal 730. The RI is used to indicate the number of effective data layers of the PDSCH. The base station 720 may obtain the number of code words (CWs) supported by the onboard terminal 730 according to the RI reported by the onboard terminal 730. For example, if the RI is equal to 1, it indicates that the onboard terminal 730 can support one CW, and if the RI is greater than 1, it indicates that the onboard terminal 730 can support two CWs. The PMI is used to indicate an index of a codebook set. The PMI reported by the on-board terminal 730 can determine whether the communication signal transmitted over the PDSCH is an optimal signal.

[0083] Here, the control information includes location information of the on-board terminal 730 and / or beam angle adjustment information corresponding to the first transmission channel, which is a non-line-of-sight transmission channel between the reflector 710 and the base station 730. The communication information includes one or more of broadcast information, channel state information, downlink control information, and downlink traffic information, among which the downlink control information is configuration information corresponding to the downlink traffic information, and is used to configure and adjust different traffic data.

[0084] In an exemplary embodiment, after obtaining the position information of the onboard terminal 730, the reflecting device 710 can determine the angle of the beam corresponding to the target transmission channel between the reflecting device 710 and the onboard terminal 730 based on the position information of the reflecting device 710 itself and the position information of the onboard terminal 730, and then adjust the angle of the beam corresponding to the target transmission channel based on this angle, so that the communication information forwarded by the reflecting device 710 can be accurately received by the onboard terminal 730, and the signal quality of the air coverage can be improved.

[0085] It should be noted that the uplink channels in the information transmission system (the on-board terminal 730 transmits to the channel of the base station 720 via different transmission channels) can correspond to each transmission channel depending on the type of transmitting antenna used by the on-board terminal 730.

[0086] In the information transmission system of the present application, by disposing a reflecting device between the base station (and / or RF device) and the on-board terminal, a target transmission channel is added in addition to the conventional transmission channel between the base station and the on-board terminal, and the number of simultaneous data streams transmitted from the base station to the on-board terminal is increased, thereby enabling the air-to-air coverage wireless communication system to support multi-streaming and improving the communication rate of the terminal.

[0087] Fig. 8 is a flowchart of downstream information transmission in the information transmission system provided by the present application. As shown in Fig. 8, the information transmission system may include a plurality of reflecting devices (for example, a first reflecting device 711, a second reflecting device 712, a third reflecting device 713, ..., an Nth reflecting device 71N), where N is an integer equal to or greater than 1.

[0088] 8, the downstream transmission channel in the information transmission system is for transmitting communication information transmitted from the base station 720 to the on-board terminal 730. The downstream transmission channel includes: 0) 0th downstream channel: base station 720 → on-board terminal 730; 1) 1st downstream channel: base station 720 → 1st reflecting device 711 → on-board terminal 730; 2) 2nd downstream channel: base station 720 → 2nd reflecting device 712 → on-board terminal 730; 3) 3rd downstream channel: base station 720 → 3rd reflecting device 713 → on-board terminal 730; ...; N) Nth downstream channel: base station 720 → Nth reflecting device 71N → on-board terminal 730.

[0089] The N reflecting devices may include active devices or passive devices. Here, the passive device means that the reflecting device cannot automatically adjust the reflection weight between the onboard terminal 730. When mounted, the mounting position of the passive reflecting device is a position determined by a preset network planning parameter, and the mounting position includes one or more of mounting angle information, mounting height information, and distance information between the passive reflecting device and the base station 720. At this time, the passive reflecting device may use a beam whose beam width is equal to or greater than a preset width threshold (i.e., a wide beam) to increase the probability that the onboard terminal 730 receives communication information.

[0090] Here, the beam width includes the horizontal beam width and the vertical beam width. The horizontal beam width refers to the angle between two directions where the radiation power on both sides of the maximum radiation direction in the horizontal direction is reduced by 3 dB. The vertical beam width refers to the angle between two directions where the radiation power on both sides of the maximum radiation direction is reduced by 3 dB in the vertical direction. The preset width threshold includes the half-power beam width.

[0091] The active device can automatically adjust the reflection weight of the beam corresponding to the target transmission channel between the onboard terminal 730 through the reflecting device based on the control information transmitted from the base station 720, so that the communication information forwarded by the reflecting device can reach the onboard terminal 730 smoothly, thereby improving the signal quality of the onboard terminal 730.

[0092] In one exemplary embodiment, the base station 720 generates a beam with a fixed radiation angle and matches the angle of this beam with surrounding reflectors to ensure that control and communication information transmitted from the base station 720 is transmitted accurately to each reflector.

[0093] Here, the downstream information transferred from each reflector to the on-board terminal 730 is only communication information, and does not include control information transmitted from the base station 720 to each reflector. Also, the on-board terminal 730 receives the communication information transmitted from the base station 720 via each different downstream transmission channel.

[0094] In one exemplary embodiment, the base station 720 may obtain location information of the onboard terminal 730 and location information of each reflecting device through a Global Positioning System (GPS), and further determine an angle corresponding to the beam of the target transmission channel between each reflecting device and the onboard terminal 730 based on the above location information.

[0095] In one exemplary embodiment, the reflecting device includes a plurality of used reflecting units, and may select a target reflecting unit from the plurality of used reflecting units based on position information of the onboard terminal 730 and position information of the reflecting device itself, determine a reflection weight corresponding to the target reflecting unit, and determine an angle corresponding to the beam of a target transmission channel between the reflecting device and the onboard terminal 730 based on the reflection weight corresponding to the target reflecting unit (or the reflection weight of the target reflecting unit).

[0096] In an exemplary embodiment, the antenna used in the on-board terminal 730 in the information transmission system may be an omnidirectional antenna, or a directional antenna if the direction is adjustable. Figure 9 is a flow chart of upstream information transmission using an omnidirectional antenna in the information transmission system provided by the present application. Figure 10 is a flow chart of upstream information transmission using a directional antenna in the information transmission system provided by the present application.

[0097] As shown in Fig. 9 or 10, the upstream transmission channel in the information transmission system is for transmitting communication information transmitted from the on-board terminal 730 to the on-board terminal 720. The upstream transmission channel includes: 0) 0th downstream channel: on-board terminal 730 → base station 720; 1) 1st downstream channel: on-board terminal 730 → 1st reflecting device 711 → base station 720; 2) 2nd downstream channel: on-board terminal 730 → 2nd reflecting device 712 → base station 720; 3) 3rd downstream channel: on-board terminal 730 → 3rd reflecting device 713 → base station 720; ...; N) Nth downstream channel: on-board terminal 730 → Nth reflecting device 71N → base station 720.

[0098] As shown in Fig. 9, the antenna used for the on-board terminal 730 is an omnidirectional antenna with a wide corresponding beam (i.e., the beam width of the beam corresponding to the omnidirectional antenna is equal to or larger than a preset width threshold). The radiated energy of the omnidirectional antenna may affect not only the LOS distance between the on-board terminal 730 and the base station 720, but also the NLOS distance between the on-board terminal 730 and other reflectors (i.e., there may be multiple reflectors between the on-board terminal 730 and the base station 720, blocking the communication signal between the on-board terminal 730 and the base station 720). In this case, the base station 720 processes the received signal using a maximum ratio combining method based on the magnitude of the reflected energy corresponding to each reflector, thereby making the communication information transmitted and acquired from the on-board terminal 730 more complete.

[0099] Here, the maximum ratio combining method determines a weight corresponding to each received signal based on the strength of the received signal, and performs weighted combining processing on each received signal to make the processed received signal clearer, thereby ensuring that more complete response information can be obtained from the processed received signal.

[0100] 10, the antenna used for the on-board terminal 730 is an adjustable directional antenna with a narrow corresponding beam (i.e., the beam width of the beam corresponding to the directional antenna is less than a preset width threshold). The main radiated energy of the directional antenna acts on the LOS distance between the on-board terminal 730 and the base station 720, so that the uplink communication information transmitted from the on-board terminal 730 reaches the base station 720 more accurately.

[0101] Using an omni-directional antenna or an adjustable directional antenna for the on-board terminal 730 increases the number of simultaneous data streams between the on-board terminal 730 and the base station 720, thereby improving the communication rate of the terminal.

[0102] In an exemplary embodiment, the base station 720 in the information transmission system may transmit downlink communication signals using a transmission channel based on a synchronization signal and a PBCH block. Figure 11 is a flow chart of a downlink communication signal transmission using a transmission channel based on a synchronization signal and a PBCH block in the information transmission system provided by the present application.

[0103] As shown in FIG. 11, the information transmission system is a 5G-based Time Division Dual (TDD) air-to-air coverage wireless communication system. Here, the base station 720 corresponds to two reflectors (i.e., a first reflector 711 and a second reflector 712), and each reflector is an active device. Here, the beams transmitted from the base station 720 include a first single-sideband modulated beam 741, a second single-sideband modulated beam 742, a third single-sideband modulated beam 743, and a fourth single-sideband modulated beam 744. The third single-sideband modulated beam 743 corresponds to the first reflector 711, and the fourth single-sideband modulated beam 744 corresponds to the second reflector 712.

[0104] In an exemplary embodiment, the base station 720 in the data transmission system may transmit downlink communication signals based on the channel state information. Figure 12 is a flow chart of the downlink communication signal transmission based on the channel state information in the data transmission system provided by the present application.

[0105] Here, the channel state information is used to represent channel attributes of a communication link, including attenuation coefficients in each transmission channel of a communication signal, such as one or more of signal scattering information, environmental fading (fading, multipath fading or shadowing fading) information, and power decay of distance information.

[0106] In a multi-antenna system, the base station 720 may transmit multiple beams. As shown in Fig. 12, the beams transmitted from the base station 720 include a first channel condition beam 751, a second channel condition beam 752, a third channel condition beam 753 and a fourth channel condition beam 754. The channel condition information transmitted by each channel condition beam can ensure the reliability of communication.

[0107] The base station 720 directs different transmit beams to different reflectors according to ports corresponding to the channel state information-based reference signal (CSI-RS), for example, making the third channel state beam 753 correspond to the first reflector 711, or the fourth channel state beam 754 correspond to the second reflector 712, etc., so that the terminal can obtain a more accurate channel estimation.

[0108] 13 is a flowchart of downstream information transmission based on active RIS in the information transmission system provided by the present application. As shown in FIG. 13, the base station 720, the first on-board terminal 731, and the second on-board terminal 732 perform downstream communication by the following method.

[0109] First, the base station 720 transmits a first control signal 7631 to the first reflecting device 711, and causes the first reflecting device 711 to adjust the radiation angle between it and the first on-board terminal 731 based on the first control signal 7631. At the same time, the base station 720 transmits a second control signal 7632 to the second reflecting device 712, and causes the second reflecting device 712 to adjust the radiation angle between it and the second on-board terminal 732 based on the second control signal 7632.

[0110] In one exemplary embodiment, the base station 720 may transmit the first control signal 7631 and / or the second control signal 7632 over a communication channel in a WIFI or 4G communication network.

[0111] Next, the base station 720 transmits first downlink communication information at a first time using a time division multiplexed beam 7611 at a first time, and transmits second downlink communication information at a second time using a time division multiplexed beam 7621 at a second time, using the TDD communication method.

[0112] When the first reflecting device 711 receives first downstream communication information, it transfers the first downstream communication information to the first on-board terminal 731 using the time division multiplexed beam 76111 at a first time. When the first reflecting device 711 receives second downstream communication information, it transfers the second downstream communication information to the first on-board terminal 731 using the time division multiplexed transfer beam 76211 at a second time.

[0113] When the second reflecting device 712 receives a first downstream communication information, it forwards the first downstream communication information to the second on-board terminal 732 using the time division multiplexed beam 76112 at a first time. When the second reflecting device 712 receives a second downstream communication information, it forwards the second downstream communication information to the second on-board terminal 732 using the time division multiplexed forwarding beam 76212 at a second time.

[0114] By using the first reflecting device and the second reflecting device to forward different downstream communication information transmitted from the base station to the on-board terminal at different times, the on-board terminal can receive the downstream communication information transmitted from the base station via multiple transmission channels, increasing the number of simultaneous data streams transmitted from the base station to the on-board terminal, thereby enabling the information transmission system to support multi-streaming and improving the communication rate of the terminal.

[0115] Figure 14 is a flow chart of upstream information transmission based on active RIS in the information transmission system provided by the present application. As shown in Figure 14, the third upstream feedback beam 773 used by the first on-board terminal 731 and the fourth upstream feedback beam 774 used by the second on-board terminal 732 may be corresponding beams based on directional antennas (e.g., adjustable directional antennas) or corresponding beams based on non-directional antennas (e.g., omni antennas).

[0116] Here, the beam width of the beam corresponding to the adjustable directional antenna is different from the beam width of the beam corresponding to the omnidirectional antenna. If the downstream transmission channel of a certain reflector is a channel determined based on the beam corresponding to the adjustable directional antenna, the upstream transmission channel must also be a channel determined based on the beam corresponding to the adjustable directional antenna. Similarly, if the downstream transmission channel of a certain reflector is a channel determined based on the beam corresponding to the omnidirectional antenna, the upstream transmission channel must also be a channel determined based on the beam corresponding to the omnidirectional antenna, in order to improve the channel gain of the upstream transmission channel (e.g., the fading situation of the upstream channel).

[0117] As shown in FIG. 14, a first on-board terminal 731 and a second on-board terminal 732 perform uplink communication with a base station 720 in the following manner.

[0118] The first on-board terminal 731 may transmit the first uplink feedback information to the base station 720 by the third uplink feedback beam 773, or may forward the first uplink feedback information transmitted and received from the first on-board terminal 731 to the base station 720 using the first uplink feedback beam 771 via the first reflecting device 711. The base station 720 can obtain the first uplink feedback information transmitted from the first on-board terminal 731 through multiple different transmission channels, improve the quality of the received signal, and ensure the completeness and accuracy of the received first uplink feedback information.

[0119] Similarly, the second on-board terminal 732 may transmit second upstream feedback information to the base station 720 by the fourth upstream feedback beam 774, or may forward the received second upstream feedback information transmitted from the second on-board terminal 732 to the base station 720 using the second upstream feedback beam 772 via the second reflector 712. The base station 720 can obtain the second upstream feedback information transmitted from the second on-board terminal 732 through multiple different transmission channels, thereby improving the quality of the received signal, and ensuring the integrity and accuracy of the received second upstream feedback information.

[0120] In one exemplary embodiment, the information transmission system is a 4G-based Frequency Division Duplexing (FDD) air-to-air coverage wireless communication system, where the information transmission system includes three passive reflectors (i.e., a third reflector 713, a fourth reflector 714 and a fifth reflector 715), a base station 720, a first on-board terminal 731 and a second on-board terminal 732.

[0121] Figure 15 is a flow chart of downstream information transmission based on passive RIS in the information transmission system provided by the present application. As shown in Figure 15, the base station 720 corresponds to the third reflector 713, the fourth reflector 714 and the fifth reflector 715, respectively, and each of the passive reflectors uses a beam whose beam width is equal to or greater than a preset width threshold (i.e., a wide beam).

[0122] The base station 720 transmits downlink information by broadcast using a first downlink transmission beam 781, thereby allowing the first onboard terminal 731 and the second onboard terminal 732 to acquire the downlink information. Here, the downlink information includes synchronization information and / or downlink broadcast information, and the first downlink transmission beam is a beam corresponding to a physical downlink shared channel (PDSCH).

[0123] When the third reflecting device 713 determines that it has received downstream information transmitted from the base station 720, it forwards the downstream information to the first on-board terminal 731 using the second downstream transmission beam 782. When the fourth reflecting device 714 determines that it has received downstream information transmitted from the base station 720, it forwards the downstream information to the second on-board terminal 732 using the third downstream transmission beam 783. When the fifth reflecting device 715 determines that it has received downstream information transmitted from the base station 720, it forwards the downstream information to the second on-board terminal 732 using the fourth downstream transmission beam 784.

[0124] By forwarding downstream information transmitted from the base station through multiple passive reflectors, the number of data streams received by the on-board terminal is increased, which enables the 4G-based FDD air-to-air coverage radio communication system to support multi-streaming and improves the terminal's communication rate.

[0125] 16 is a flowchart of upstream information transmission based on a passive RIS in the information transmission system provided by the present application, where each on-board terminal may use a directional antenna with adjustable direction, and each reflector may use a beam with a beam width equal to or greater than a preset width threshold (i.e., a wide beam) for each passive reflector.

[0126] As shown in FIG. 16, the first onboard terminal 731 transmits first uplink information to the base station 720 using a second uplink transmission beam 792, and the second onboard terminal 732 transmits second uplink information to the base station 720 using a fourth uplink transmission beam 794.

[0127] When the third reflecting device 713 determines that it has received the first uplink information transmitted from the first on-board terminal 731, it forwards the first uplink information to the base station 720 using the first uplink transmission beam 791. Therefore, the first uplink information received by the base station 720 is information obtained through two different transmission channels (i.e., the LOS distance transmission channel between the first on-board terminal 731 and the base station 720, and the NLOS distance transmission channel consisting of the first on-board terminal 731, the third reflecting device 713, and the base station 720), and the number of data streams between the base station 720 and the first on-board terminal 731 increases.

[0128] When the fourth reflecting device 714 determines that it has received the second upstream information transmitted from the second onboard terminal 732, it forwards the second upstream information to the base station 720 using the third upstream transmission beam 793. When the fifth reflecting device 715 determines that it has received the second upstream information transmitted from the second onboard terminal 732, it forwards the second upstream information to the base station 720 using the fifth upstream transmission beam 795.

[0129] Therefore, the second uplink information received by the base station 720 is information obtained via three different transmission channels (i.e., the LOS distance transmission channel between the second onboard terminal 732 and the base station 720, the NLOS distance transmission channel consisting of the second onboard terminal 732, the fourth reflector 714 and the base station 720, and the LOS distance transmission channel consisting of the second onboard terminal 732, the fifth reflector 715 and the base station 720), which increases the number of data streams between the base station 720 and the second onboard terminal 732, thereby improving the channel gain of the uplink transmission channel of the base station 720 (e.g., the fading condition of the uplink channel).

[0130] It should be noted that the present invention is not limited to the specific configurations and processes described in the above embodiments and illustrated in the drawings. For ease of explanation, detailed descriptions of known methods are omitted herein, and the specific operation processes of the above-described systems, modules, and units may refer to the corresponding processes in the above-described method embodiments, and the description thereof is omitted herein.
