Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to an antenna control device, a remote radio unit and a communication system. BACKGROUND

[0002] With the evolution of the 5th generation mobile networks (5G), indoor services, especially data services, gradually increase, and indoor coverage becomes more and more important. Indoor coverage scenarios include shopping malls, hospitals, office buildings, hotels, transportation hubs, etc. For indoor environments, partitions are diverse, including open scenarios and partitioned scenarios. Figure 1 As shown in FIG. 1, Figure 1 In (a), the coverage distance of the base station is improved, Figure 1 In (b), the coverage radius of the base station is improved. It can be seen that if the EIRP (Effective Isotropic Radiated Power) of the transmitter in the base station is larger, the coverage distance is larger, and the number of transmitters in the same area will be reduced, thereby reducing the number of deployments of each unit, installation and wiring time, and reducing the cost and power consumption of the entire station. By improving the EIRP to improve the coverage distance to reduce the cost, if the antenna inlet power level is unchanged, the EIRP needs to be improved by improving the omnidirectional antenna gain of the antenna. How to improve the omnidirectional gain is particularly important.

[0003] In the prior art, when the base station antenna radiates omnidirectionally, it is limited by the height of the vertical plane, and most of the power is below, the included angle of the 3dB (Decibel, dB) radiation direction is generally within 60 degrees (included angle θ with the vertical line), the gain is low, and the coverage range is limited. When the base station uses a directional antenna, it has a large directional gain in the main lobe direction, but the gain is low in the remaining (except the main lobe) direction. When multiple antennas are arranged on the inner side of the communication module, the thickness of the communication module limits the size and layout of the antenna, and the gain of the antenna array in the communication module plane is small.

[0077] In a specific implementation, each RRU is configured to: receive a downlink signal from the baseband processing unit, modulate the downlink signal into a radio frequency signal, and transmit the radio frequency signal through an antenna; and receive a radio frequency signal from the antenna, perform corresponding signal processing, and send the radio frequency signal to the baseband processing unit, so that the baseband processing unit further processes the signal.

[0078] The antenna control device involved in the embodiments of the present application is applicable to any RRU in the RR system.

[0079] Second, analog feed digital signal distribution system, such as Figure 3 ​​​As shown in the analog feeding digital signal distribution system, in order to achieve zoom and expand the base station coverage, reduce the uplink noise superposition, optical fiber and network cable, optical fiber and optical repeater are adopted.

[0081] In a specific implementation, the access unit comprises a frequency conversion unit, an analog-to-digital conversion unit and a mixing unit, wherein the access unit is specifically configured to: perform signal processing on the downlink radio frequency signal of the 5G or the like source through the frequency conversion unit and the analog-to-digital conversion unit to obtain a downlink digital signal, and send the downlink digital signal to the expansion module; and receive the uplink digital signal sent by the expansion module, process the uplink digital signal to obtain an analog intermediate frequency signal, and convert the analog intermediate frequency signal into an uplink 5G or the like system radio frequency signal through the mixing unit.

[0082] The antenna control device related to the embodiments of the present application is applicable to any RRU in the analog feeding digital signal distribution system.

[0083] In a specific implementation, each RRU comprises a mixing unit, which is specifically configured to: receive the downlink digital signal sent by the expansion module, decompose each type of data, perform digital signal processing, restore the radio frequency signal through digital-to-analog conversion, and finally emit the radio frequency signal through an antenna; and convert the 5G uplink radio frequency signal received through the antenna into an intermediate frequency signal through the mixing unit, transmit the intermediate frequency signal to the expansion module after analog-to-digital conversion and signal processing.

[0086] It should be noted that the antenna control device involved in the embodiments of the present application can also be applicable to other 5G and the like wireless communication systems, without specific limitation.

[0087] In the prior art, when the RRU of the base station adopts an omnidirectional antenna, the antenna radiates omnidirectionally, and is limited by the height of the vertical plane, so that the main power is below, the included angle of the 3dB radiation direction is generally within 60 degrees (the included angle θ with the vertical line), the gain is low, and the coverage range is limited. When the RRU of the base station adopts a directional antenna, it has a large directional gain in the direction of the main lobe, but the gain is low in the remaining (except the main lobe) directions. When multiple antennas are placed at the inner bottom of the communication unit, the thickness of the unit itself limits the size and layout of the antennas, and the gain of the antenna array in the unit plane is small. The above prior art needs to deploy a large number of units, and the cost of the whole station is high.

[0092] It should be noted that in each transceiving channel in the aforementioned main module, there is a corresponding combination relationship between each transceiving channel unit and the antenna object, for example, the transceiving channel unit 1 switches between the antenna object 11~antenna object 1m, and the transceiving channel unit n switches between the antenna object n1~antenna object nm, in the specific implementation, when the downlink or uplink is scheduled to a user, the corresponding antenna object is selected, and the antenna selection control unit controls the transceiving channel unit to switch between the corresponding multiple antenna objects, wherein when the antenna object is a directional antenna, the antenna selection control unit can be realized by a single-pole multi-throw radio frequency switch, and when the antenna object is a reconstructed antenna beam, the antenna selection control unit controls the direction of the reconstructed antenna beam.

[0093] It should be further noted that by arranging multiple antenna objects corresponding to multiple transceiving channels on the peripheral side of the horizontal four sides of the main module, multiple antenna arrays can be formed, that is, the deployment of multiple antenna arrays is completed, and each antenna array in the multiple antenna arrays can have multiple antenna objects. Here, the number of antenna arrays in the main module is not specifically limited, for example, the main module can include 3, 4 or other number of antenna arrays, further, the number of antenna objects on one antenna array is not specifically limited, for example, one antenna array can include 2, 4 or other number of antenna objects.

[0097] Next, the first implementation mode is described in detail:

[0098] The transceiver unit in each transceiver channel of the main module performs signal scanning through time division to determine a first antenna array surface, which is the antenna array surface that receives the strongest signal for the UE in the multiple antenna array surfaces in the main module; and the first antenna array surface is used to implement the transceiving of uplink and downlink physical channels.

[0099] In a possible implementation of the embodiments of the present application, when the main module is in communication connection with the first UE, the transceiving channel unit in each transceiving channel of the main module can perform signal scanning through time division to determine the antenna array surface in the plurality of antenna array surfaces in the main module from which the first UE receives the strongest signal. If the antenna array surface in the main module corresponds to one SS Block beam, that is, one antenna array surface corresponds to at least one SS Block beam, and different antenna array surfaces correspond to different at least one SS Block beam, the transceiving channel unit in each transceiving channel of the main module can perform SS Block scanning to determine the first antenna array surface, which is the antenna array surface in the plurality of antenna array surfaces in the main module from which the first UE receives the strongest SSB signal. Then, the corresponding at least one first SS Block beam is determined according to the first antenna array surface, so as to cover the first UE through the at least first SS Block beam of the first antenna array surface. In other words, the baseband processing unit and the scheduling unit of the base station will schedule the downlink radio frequency signal (such as PDSCH service) between the first UE to the first antenna array surface. Further, the main module can number a plurality of SS Block beams to obtain a plurality of beam numbers, one SS Block beam corresponds to one beam number, and different SS Block beams correspond to different beam numbers. Because one antenna array surface corresponds to at least one SS Block beam, and different antenna array surfaces correspond to different at least one SS Block beam, that is, one antenna array surface corresponds to at least one beam number.

[0100] For example, refer to Figure 6 , Figure 6 An application scenario of an antenna control device provided by the embodiments of the present application is shown in the figure. The main module 610 includes a first antenna array surface 611, a second antenna array surface 612, a third antenna array surface 613, and a fourth antenna array surface 614. The first antenna array surface 611 corresponds to SS Block beam 1, the second antenna array surface 612 corresponds to SS Block beam 2, the third antenna array surface 613 corresponds to SS Block beam 3, and the fourth antenna array surface 614 corresponds to SS Block beam 4. That is, one antenna array surface corresponds to one SS Block beam. The main module can select the home array surface of the first UE based on different scheduling strategies. For example, when each transceiving channel of the main module performs SS Block beam scanning through time division, if it is determined that the downlink radio frequency signals of the first UE 620 in the 4 transceiving channels in the direction of the antenna array surface 614 are all strong, SS Block beam 4 can be selected to cover the first UE 620, that is, the base station will schedule the downlink radio frequency signal (such as PDSCH service) between the first UE to the fourth antenna array surface 614.

[0101] In another possible implementation of the embodiments of the present application, when the master module is in a communication connection with the first UE, the first UE can determine the antenna array belonging to the first UE based on the CSI-RS, in the case that the channel state information-reference signal (CSI-RS) measurement is configured.

[0102] For example, when the master module includes a first antenna array, a second antenna array, a third antenna array and a fourth antenna array, the first antenna array corresponds to a CSI-RS beam 1, the second antenna array corresponds to a CSI-RS beam 2, the third antenna array corresponds to a CSI-RS beam 3 and the fourth antenna array corresponds to a CSI-RS beam 4; when the first UE determines, through the CSI-RS measurement, that the CSI-RS beam corresponding to the antenna array 614 closest to the first UE is the CSI-RS beam 4, it is determined that the first UE is covered by the CSI-RS beam 4, that is, the downlink radio frequency signal (such as PDSCH service) between the base station and the first UE is scheduled to the fourth antenna array 614.

[0103] Next, the second implementation is described in detail.

[0104] The transceiver unit in each transceiver channel of the master module performs time division signal scanning to determine a plurality of first antenna objects, the plurality of first antenna objects being antenna objects in a plurality of antenna objects corresponding to the master module and having a path signal higher than a preset value to the second UE, the plurality of antenna objects being antenna objects on different antenna arrays, and the second UE is covered by the plurality of first antenna objects, so as to realize the transceiving of the uplink and downlink physical channels through the plurality of antenna objects of the plurality of antenna arrays.

[0105] In a possible implementation of the embodiments of the present application, one CSI-RS beam corresponds to a plurality of directional antennas of a plurality of antenna arrays, and when the master module is in a communication connection with the second UE, the transceiver unit in each transceiver channel of the master module can determine a plurality of first directional antennas through antenna scanning, the plurality of first directional antennas being directional antennas in a plurality of directional antennas corresponding to the master module and having a path signal higher than a preset value to the second UE; the uplink and downlink physical channels are transceived through the plurality of first directional antennas (which can be directional antennas of different antenna arrays).

[0106] Here, for multiple transceiving channels, each CSI-RS beam can correspond to part of the directional antennas of multiple antenna arrays. For example, the main module includes four antenna arrays, each antenna array has 4 directional antennas, CSI-RS beam 1 can correspond to directional antenna 3 and directional antenna 4 of antenna array 1 and directional antenna 1 and directional antenna 2 of antenna array 2; CSI-RS beam 4 corresponds to directional antenna 1 and directional antenna 2 of antenna array 1 and directional antenna 3 and directional antenna 4 of antenna array 4. Wherein, the scheduling method of multiple CSI-RS beams can define multiple beams through algorithm according to the multipath channel characteristics of different building environments, select different antenna arrays to transmit, and maximize the improvement of spatial multi-flow capability. That is, in this embodiment, for each CSI-RS beam, the corresponding part of the antennas of multiple different antenna arrays can be selected by the antenna selection control unit to improve the spatial multi-flow capability and inter-cell interference rejection capability.

[0107] For example, please refer to Figure 7 , Figure 7 The application scenario of another antenna control device provided by the embodiment of the application is shown in the figure. Taking four directional antennas on each side as an example, when the main module 710 is in communication connection with the second UE 720, if the channel detection finds that the paths of directional antenna A1 and directional antenna A2 of the antenna array 711 to the second UE are relatively strong, but the correlation between directional antenna A3 and directional antenna A4 and directional antenna A1 and directional antenna A2 is high, and the paths of directional antenna A3 and directional antenna A4 of the antenna array 712 to the UE are also relatively strong and the correlation with directional antenna A1 and directional antenna A2 of the antenna array 711 is low, the CSI-RS beams corresponding to directional antenna A1 and directional antenna A2 of the antenna array 711 and directional antenna A3 and directional antenna A4 of the antenna array 712 can be selected to cover the UE, that is, the base station schedules the downlink radio frequency signal (such as PDSCH service) between the base station and the first UE to directional antenna A1 and directional antenna A2 of the antenna array 711 and directional antenna A3 and directional antenna A4 of the antenna array 712, as shown in Figure 8 The multipath between the user equipment and the base station in this case is shown in the figure.

[0108] It can be seen that in the embodiment of the application, multiple antenna objects are deployed on the side of the main module in the antenna control device to obtain multiple antenna arrays, and the benefits of omnidirectional coverage are obtained by selecting multiple antenna arrays or directly selecting multiple antenna objects, EIRP is increased, the number of main modules is reduced, and the cost of the entire station is reduced.

[0109] Further, please refer to Figure 9 , Figure 9 for Figure 5A possible structure diagram of a single transceiving channel in the main module is shown. As can be seen, the transceiving channel unit in the single transceiving channel in the main module can include a receiving channel unit, a transmitting channel unit, and an uplink / downlink signal combining and splitting unit. The transceiving channel in the main module can select an antenna object from a plurality of antenna objects. The downlink (DL) channel signal and the uplink (UL) channel signal in the base station are transmitted and received on the antenna object of the antenna array surface.

[0110] As can be seen, in this example, the antenna control device can schedule multiple users based on the New Radio (NR) beam mechanism and SS Block beam scanning or CSI-RS measurement, and obtain the benefits of omnidirectional coverage through time division selection of multiple antenna objects, thereby increasing the EIRP and improving the communication effect, reducing the number of modules, and ultimately reducing the cost of the entire station. When multiple antenna objects constitute multiple antenna array surfaces, each antenna array surface has multiple antenna objects, and the antenna control device can select different antenna array surfaces to improve the channel selection capability. The correlation between multiple antenna objects is low, and the multi-stream capability is strong. In addition, the beam direction is staggered through time division scheduling between cells to improve the inter-cell interference suppression capability.

[0111] Please refer to Figure 10 , Figure 10 Another structure diagram of an antenna control device provided by the embodiments of the present application is shown. Figure 10 The main module in the antenna control device shown in Figure 5 The main module in the antenna control device shown in the figure is provided with at least one omnidirectional antenna arranged at the bottom of the main module.

[0112] It should be noted that the number and position of the antenna objects arranged on each antenna array surface are not specifically limited, and the number and arrangement position of the omnidirectional antennas arranged in the lower end surface of the main module are not specifically limited. Please refer to​Figure 11 and Figure 12 , Figure 11 a side view of an antenna deployment corresponding to the main module, Figure 12 a top view of an antenna deployment corresponding to the main module, it can be seen that the main module is deployed with four antenna arrays around, each of which includes an antenna object, and the lower end surface is provided with two omnidirectional antennas, in addition, the main module includes a shielding cover, a radiator, a transceiving channel unit and an antenna selection control switch arranged inside, etc., which are not shown in the figure.

[0113] Please refer to Figure 13 , Figure 13 a possible structure diagram of a single transceiving channel in the main module provided by the embodiment of the application, it can be seen that in the main module, the transceiving channel unit of the single transceiving channel includes a receiving channel unit, a transmitting channel unit, an uplink and downlink signal combining and splitting unit, and one transceiving channel in the main module can select an antenna from multiple antenna objects in multiple antenna arrays, the downlink channel signal and the uplink channel signal in the base station are transmitted and received on the antenna array, and the uplink channel signal can be partially or entirely received in the omnidirectional antenna.

Figure 14 Figure 10 It can be seen that in the embodiment of the application, multiple omnidirectional antennas are arranged at the bottom of the main module in the antenna control device, so as to receive the uplink signal through the omnidirectional antenna, specifically, all or part of the uplink channel signals can be received on the omnidirectional antenna, and the uplink signal can be selected to be received on the original antenna object or simultaneously received on the original antenna object and the omnidirectional antenna, and when the downlink signal is time-division scanned in space, some physical channels of the uplink can be ensured to be received omnidirectionally, the time for waiting for confirmation of uplink and downlink interaction is reduced, and the downlink throughput rate of the main module is improved.

For the added channel combining and splitting unit and the signal and power combining and splitting unit, the foregoing has been described, please refer to the foregoing description, which will not be repeated here.

[0121] Each expansion module, relative to the connected main module, can not include part of the functional units in the main module, such as the transceiving channel unit, the channel combining and splitting unit, etc.

[0122] For reference Figure 15 As shown in the structure of the main module in the antenna selection device, the following exemplary description is not limited to the structure of the main module, that is, in the specific implementation, the structure of the main module can also be other structures that can be easily thought of by those skilled in the art based on various antenna selection devices provided by the embodiments of the present application. Figure 16 As shown in the specific implementation of the antenna control device, the following exemplary description is not limited to the structure of the main module, that is, in the specific implementation, the structure of the main module can also be other structures that can be easily thought of by those skilled in the art based on various antenna selection devices provided by the embodiments of the present application.

[0123] For example, please refer to Figure 17 , Figure 17 For the various antenna selection devices provided by the embodiments of the present application Figure 16In the specific implementation of the antenna control device shown, in each of the expansion modules, each of the transceiving channels includes an antenna selection control unit, a power supply and control management unit, a signal and power combining and splitting unit, and a plurality of antenna objects disposed on the side of the expansion module; the antenna selection control unit is configured to control the transceiving channel unit in the main module corresponding to the antenna selection control unit to switch between the plurality of antenna objects; the plurality of antenna objects are configured to receive electromagnetic wave signals and convert the electromagnetic wave signals into radio frequency signals, and are configured to convert radio frequency signals into electromagnetic wave signals and transmit the electromagnetic wave signals; the signal and power combining and splitting unit is configured to split the second coupling signal from the main module to obtain the first coupling signal and the third coupling signal, and transmit the first coupling signal to the corresponding antenna selection control unit, and transmit the third coupling signal to the corresponding power supply and control management unit, the third coupling signal being a signal obtained by coupling the power signal, the antenna switching control signal, and the operation and maintenance management signal; and is configured to combine the radio frequency signal of the antenna selection control unit and the operation and maintenance management signal to obtain a fourth coupling signal, and transmit the fourth coupling signal to the main module through the transmission cable; and is configured to, in the case of connecting the expansion module through a transmission medium, split the second coupling signal received from the main module to obtain a fifth coupling signal corresponding to the connected expansion module, transmit the fifth coupling signal to the connected expansion module through the transmission medium, to realize the control of the main module on the connected expansion module, the fifth coupling signal including the signal of the transceiving channel, the power signal, the antenna switching control signal, and the operation and maintenance management signal; and is configured to transmit a sixth coupling signal received from the connected expansion module to the main module, the sixth coupling signal including the radio frequency signal and the operation and maintenance management signal; the power supply and control management unit is configured to separate and demodulate the third coupling signal; and is configured to modulate the operation and maintenance management signal of the expansion module, and transmit the modulated operation and maintenance management signal to the main module through the transmission cable, so that the main module implements operation and maintenance management on the expansion module. It can be seen that, in the embodiment of the present application, in the antenna control device, the main module connects at least one expansion module and controls the at least one expansion module, each expansion module is less than the main module in part of the functional units in the main module, such as the transceiving channel unit, the channel combining and splitting unit, etc., so the expansion module has fewer functional units than the main module, and has lower cost.

[0124] For example, please refer to Figure 18 , Figure 18 The application provides Figure 16In another specific implementation of the antenna control device shown, the device further comprises at least one transmission cable and at least one expansion module, the at least one expansion module is connected to the main module through the at least one transmission cable; each of the at least one expansion module comprises a plurality of transceiving channels, the plurality of transceiving channels comprises a first transceiving channel and at least one second transceiving channel, the first transceiving channel comprises a power supply and control management unit, a signal and power combining and splitting unit, an antenna selection control unit and a plurality of antenna objects arranged on the side of the expansion module, each of the at least one second transceiving channel comprises a signal combining and splitting unit, an antenna selection control unit and a plurality of antenna objects arranged on the side of the expansion module; in the first transceiving channel, the signal and power combining and splitting unit is used to split the second coupling signal from the main module to obtain the first coupling signal and the third coupling signal, and transmit the first coupling signal to the corresponding antenna selection control unit, and transmit the third coupling signal to the corresponding power supply and control management unit, the third coupling signal is a signal coupled by the power signal, the antenna switching control signal and the operation and maintenance management signal; and a radio frequency signal and an operation and maintenance management signal of the antenna selection control unit are combined to obtain a fourth coupling signal, and the fourth coupling signal is sent to the main module through the transmission cable; and in the case that the expansion module is connected to another expansion module through a transmission medium, the received second coupling signal from the main module is split to obtain a fifth coupling signal corresponding to the connected expansion module, the fifth coupling signal is transmitted to the connected expansion module through the transmission medium to realize the control of the main module on the connected expansion module, the fifth coupling signal comprises a transceiving channel signal, a power signal, an antenna switching control signal and an operation and maintenance management signal; and a sixth coupling signal comprising a radio frequency signal and an operation and maintenance management signal received from the connected expansion module is sent to the main module; the power supply and control management unit is used to separate and demodulate the third coupling signal; and the operation and maintenance management signal of the expansion module is modulated and sent to the main module through the transmission cable after modulation, so that the main module implements operation and maintenance management on the expansion module; in each of the second transceiving channel, the signal combining and splitting unit is used to receive signals from the main module, and transmit the signals from the main module to the antenna selection control unit; and when connected to an expansion module, the signals from the main module are split to obtain a first signal corresponding to the connected expansion module, and the first signal is sent to the connected expansion module to realize the control of the main module on the connected expansion module;In each of the transceiving channels, the antenna selection control unit is configured to control the transceiving channel unit corresponding to the antenna selection control unit in the main module to switch between the plurality of antenna objects; the plurality of antenna objects are configured to receive electromagnetic wave signals and convert the electromagnetic wave signals into radio frequency signals, and are configured to convert radio frequency signals into electromagnetic wave signals and transmit the electromagnetic wave signals. It can be seen that in the embodiment of the present application, the antenna control device has at least one expansion module connected to the main module, each expansion module does not have a transceiving channel unit and a channel combining and splitting unit in the main module, and the entire expansion module only includes one power supply and control management unit and one signal and power combining and splitting unit, which further reduces the number of units in the expansion module, increases the EIRP, improves the communication effect, and further reduces the cost of the entire station.

[0125] It should be noted that the number of antenna array surfaces formed by the antenna objects arranged in the same expansion module is not specifically limited, the number and position of the antenna objects arranged on each antenna array surface are not specifically limited, and the number and arrangement position of the omnidirectional antennas arranged in the lower end surface of the expansion module are not specifically limited. For specific implementation, reference can be made to the layout of the main module in the antenna selection device shown in Figure 10 The layout of the main module in the antenna selection device is not repeated here.

[0126] In addition, in some specific embodiments of the present application, the plurality of antenna objects in each of the expansion modules constitute a plurality of antenna array surfaces, when the expansion module in the antenna control device is in communication connection with the second user equipment, each of the transceiving channels can select an antenna array surface or at least one antenna object (which can be on different antenna array surfaces) through time division to realize the reception of the uplink and downlink physical channels, that is, each of the transceiving channels schedules the antenna objects according to different physical channels according to the antenna array surface, or according to the antenna objects of different antenna array surfaces. The implementation manner of the expansion module for realizing the reception of the uplink and downlink physical channels can refer to the implementation manner of the main module for realizing the reception of the uplink and downlink physical channels, and the difference between the two is that the expansion module is completed under the control of the main module.

[0127] Further, the structure of the main module in the antenna selection device shown in Figure 10 The at least one expansion module further includes at least one omnidirectional antenna arranged at the bottom of the expansion module, and each of the transceiving channels further includes one of the at least one omnidirectional antenna; in each of the expansion modules, the omnidirectional antenna in each of the transceiving channels is configured to receive part or all of the electromagnetic wave signals and convert the part or all of the electromagnetic wave signals into radio frequency signals.

[0128] In specific implementation, the main module of the antenna control device can control the deployment of multiple omnidirectional antennas at the bottom of the expansion module to achieve uplink RF signal reception through the omnidirectional antennas of the expansion module. Specifically, it can receive all or part of the uplink channel signals on the omnidirectional antennas of the expansion module. Moreover, the uplink signal can be received on the original antenna object of the expansion module or simultaneously on the original antenna object of the expansion module and the omnidirectional antenna of the expansion module. Furthermore, when the downlink signal is time-division scanned in space, it can ensure that certain physical channels of the uplink are received omnidirectionally, reducing the waiting time for uplink and downlink interaction and improving the downlink throughput of the expansion module.

[0129] The main module and each of the expansion modules include a modulation / demodulation unit and a combining / splitting unit, enabling signals between the main module and each of the expansion modules to be transmitted over different transmission media, and supporting different cable types when the transmission medium is a transmission cable. The following, in conjunction with... Figure 15 , Figure 16 , Figure 17 , Figure 18 This section introduces the connection methods between the main module and at least one extension module.

[0130] For specific implementation details, please refer to [link / reference]. Figure 19 , Figure 19 Provided for the embodiments of this application Figure 16 The diagram shown illustrates the connection between a main module and an expansion module for an antenna control device. Figure 19 As shown, a main module and an expansion module may be connected via a single transmission cable or multiple transmission cables, without any specific limitation.

[0131] The main module includes multiple transceiver channels, and each of the expansion modules includes multiple transceiver channels. The main module and each expansion module can be connected in the following two ways:

[0132] For the first option, please refer to [the original text]. Figure 20 , Figure 20 Provided for the embodiments of this application Figure 16 The diagram shown illustrates the connection between another main module and expansion module corresponding to the antenna control device, as follows: Figure 20 As shown, a transceiver channel in the main module is connected to a transceiver channel in each expansion module via a single transmission cable, and different transceiver channels in the main module are connected to different transceiver channels in each expansion module via different transmission cables. That is, the number of transmission cables corresponds one-to-one with the transceiver channels of the main module and the expansion modules. In this method, the transmission cable can be an RF coaxial cable.

[0133] The second option, please refer to Figure 21 , Figure 21The antenna control device provided by the embodiment of the present application Figure 16 The connection diagram of another main module and extension module corresponding to the antenna control device shown in the figure is as follows Figure 21 As shown in the figure, in the main module, a plurality of transceiving channels, a plurality of modulation and demodulation units and a combining and splitting unit are included, wherein one transceiving channel corresponds to one modulation and demodulation unit, different transceiving channels correspond to different modulation and demodulation units, and the plurality of modulation and demodulation units are connected to the combining and splitting unit, wherein each of the modulation and demodulation units is configured to modulate the signal of the corresponding transceiving channel to realize transmission to the extension module through different transmission media, and to demodulate the signal from the extension module to transmit to the corresponding transceiving channel; the combining and splitting unit is configured to combine the signals modulated by the plurality of modulation and demodulation units and transmit to the extension module through the corresponding transmission media, and to split the signals from the extension module received through different transmission media to transmit to the corresponding modulation and demodulation unit. In the extension module, a plurality of transceiving channels, a plurality of modulation and demodulation units and a combining and splitting unit are included, wherein one transceiving channel corresponds to one modulation and demodulation unit, different transceiving channels correspond to different modulation and demodulation units, and the plurality of modulation and demodulation units are connected to the combining and splitting unit, wherein each of the modulation and demodulation units is configured to modulate the signal of the corresponding transceiving channel to realize transmission to the main module through different transmission media, and to demodulate the signal from the main module to transmit to the corresponding transceiving channel; the combining and splitting unit is configured to combine the signals modulated by the plurality of modulation and demodulation units and transmit to the main module through the corresponding transmission media, and to split the signals from the extension module received through different transmission media to transmit to the corresponding modulation and demodulation unit; and in the case that the extension module is connected to another extension module, the combining and splitting unit is configured to receive the signal from the connected extension module and transmit to the main module through the corresponding transmission media, and to split the signals from the extension module received through different transmission media to obtain the signal of the connected extension module and transmit to the connected extension module through the transmission media, to realize the control of the main module over the connected extension module. It can be seen that, when the combining and splitting unit of the main module is connected to the combining and splitting unit of the extension module through the transmission cable, through the joint action of the modulation and demodulation units and the combining and splitting unit, the signals between the main module and the extension module can be uniformly modulated onto one transmission cable, which can save the cable and reduce the deployment cost during deployment and construction, and can be modulated onto different transmission cables according to the needs, making the use more flexible. In this way, the transmission cable can be a network cable, the transmission cable can also be an optical fiber, etc.

[0134] It can be seen that, in the embodiment of the application, the main module in the antenna control device can be connected with multiple extension modules through radio frequency coaxial cables, network cables, optical fibers and the like to ensure greater EIRP, so that the communication effect is better, and the number of main modules can be saved, and the cost of the whole station is reduced. Moreover, compared with all main modules, the cost proportion of the main module is reduced by cascading combination of the main module and the low-cost and low-complexity extension module, so that the construction cost of the whole station is reduced.

[0135] In one possible example, the networking mode between the main module and the at least one extension module includes a star topology or a chain topology.

[0136] Firstly, the star topology, as shown in Figure 22 The main module includes multiple transceiver channel groups, one transceiver channel group includes multiple transceiver channels, one transceiver channel group is connected with one extension module, each extension module includes multiple transceiver channels, and different transceiver channel groups are connected with different extension modules. In this mode, for some application scenarios, the construction route can be simplified, and deployment is flexible.

[0137] Secondly, the chain topology, as shown in Figure 23 The main module includes multiple transceiver channel groups, one transceiver channel group includes multiple transceiver channels, the main module is connected with multiple extension modules in series, each extension module includes multiple transceiver channels, and in the case that each extension module is connected with the main module through other extension units, signal transmission can be performed through other extension modules. In this mode, for some application scenarios, the amount of transmission cables can be saved.

[0138] The application embodiment further provides a radio remote unit, which includes any one of the antenna selection devices.

[0139] The application embodiment further provides a communication system, which includes any one of the antenna selection devices.
