[0002] With the development of communication technology, there are more and more telecom operators, and antenna panels have become a scarce resource.

[0003] In a possible solution, two or more antennas may be integrated on the same panel, wherein different antennas may be used for transmitting and receiving different signals, thereby saving panel resources.

[0004] However, under this configuration, the downtilt angles of the antennas integrated on the same antenna panel have to remain consistent, which makes it impossible to independently adjust the signal coverage of the antennas on the same antenna panel, seriously affecting the flexibility of communication.

[0005] Therefore, it is hoped to provide a technology that can improve the flexibility of communication while saving antenna panel resources. Summary of the invention

[0006] The present application provides an antenna system that can improve communication flexibility while saving antenna panel resources.

[0008] According to the solution provided in the present application, two antennas for sending the same signal are independently configured (specifically, the mechanical downtilt angles of the antennas are independently adjustable), and an adjuster for adjusting the electrical downtilt angles of the antennas is provided for each antenna. Thus, even if at least one of the first antenna and the second antenna shares the same antenna panel with other antennas, the coverage range of the signals sent by the two antennas can be adjusted by adjusting the electrical downtilt angles, thereby being able to support improving the flexibility of communication while saving antenna panel resources.

[0009] As an example but not limitation, the antenna system further includes a first sensor for detecting the first mechanical downtilt angle, and the antenna system further includes a second sensor for detecting the second mechanical downtilt angle.

[0010] In one implementation, the antenna system further includes a third antenna configured on the first antenna.

[0011] In another implementation, the antenna system further includes a fourth antenna configured on the second antenna.

[0012] For example, the third antenna is an active antenna, and the fourth antenna is an active antenna.

[0013] Furthermore, the first antenna is a passive antenna, and the second antenna is a passive antenna.

[0014] For another example, the third antenna is a passive antenna, and the fourth antenna is a passive antenna.

[0015] Furthermore, the first antenna is an active antenna, and the second antenna is an active antenna.

[0016] In the present application, the first rotation axis and the second rotation axis are arranged in parallel.

[0017] Furthermore, the first rotation axis may be disposed at any position such as the edge or the center of the first antenna.

[0018] The second rotation axis can be configured at any position such as the edge or center of the first antenna, and is not particularly limited in the present application.

[0019] In the present application, the first regulator may be a circuit or a mechanical unit having a phase adjustment function.

[0020] In a possible implementation manner, the first regulator may also adjust the amplitude of the first sub-RF signal.

[0021] By way of example and not limitation, the first regulator includes a splitter and a phase shifter.

[0022] That is, the first sub-RF signal may be divided into two signals by a splitter, and the phase difference between the two signals may be adjusted by a phase shifter, thereby achieving adjustment of the first electrical downtilt angle.

[0023] Similarly, in the present application, the second regulator may be a circuit or a mechanical unit having a phase adjustment function.

[0024] In a possible implementation manner, the second regulator may also adjust the amplitude of the second sub-RF signal.

[0025] For example, the second regulator includes the splitter and a phase shifter.

[0026] That is, the second sub-RF signal may be divided into two signals by a splitter, and the phase difference between the two signals may be adjusted by a phase shifter, thereby achieving adjustment of the second electrical downtilt angle.

[0027] In one implementation, the antenna system also includes a first controller and a second controller, the first controller being used to control the first regulator to perform the first processing based on the target downtilt angle corresponding to the first RF signal and the first mechanical downtilt angle, and the second controller being used to control the second regulator to perform the second processing based on the target downtilt angle corresponding to the first RF signal and the second mechanical downtilt angle.

[0028] In another implementation, the first controller may be configured or integrated in the first regulator, or the second controller may be configured or integrated in the second regulator.

[0030] In another possible implementation, the antenna system further includes a second sensor, which is communicatively connected to the second controller and is configured to detect the second mechanical downtilt angle and send indication information of the second mechanical downtilt angle to the second controller.

[0031] As an example but not limitation, when the first mechanical downtilt angle and the second mechanical downtilt angle are 0, the first antenna and the second antenna are coplanar.

[0032] Alternatively, when the first mechanical downtilt angle and the second mechanical downtilt angle are 0, the first antenna and the second antenna are not coplanar.

[0033] As an example and not limitation, the antenna system also includes a third regulator, which is used to perform a third processing on the target sub-RF signal to adjust the phase difference between the first sub-RF signal and the second sub-RF signal, wherein the target sub-RF signal is at least one of the first sub-RF signal and the second sub-RF signal.

[0034] Thus, by adjusting the phase difference between the first sub-RF signal and the second sub-RF signal, the time interval between the sending times of the first sub-RF signal and the second sub-RF signal can be adjusted, thereby compensating for the deviation in the transmission time of the first sub-RF signal and the second sub-RF signal from being sent from the antenna to arriving at the receiving end due to the different downtilt angles of the first antenna and the second antenna, and enabling the receiving end to synchronously receive the first sub-RF signal and the second sub-RF signal, thereby improving the accuracy and reliability of communication.

For example, the signal received by the first antenna is recorded as signal 1, and the signal received by the second antenna is recorded as signal 2. Then, the wavelength of signal 1 and signal 2 are the same, and the data carried is the same. Thereafter, the first regulator is used to process signal 1 (corresponding to the above-mentioned first processing, for example, phase shift processing), and the second regulator is used to process signal 2 (corresponding to the above-mentioned second processing, for example, phase shift processing), and the splitter can realize the function of a combiner in the signal receiving process, that is, it is used to combine signal 1 and signal 2 processed by the regulator and send them to the radio frequency unit. It should be noted that the signal receiving process listed above is only an exemplary description, and the present application is not particularly limited thereto.

[0043] According to the solution provided in the present application, two antennas for sending signals with the same wavelength and carrying the same data are independently configured (specifically, the mechanical downtilt angles of the antennas are independently adjustable), and an adjuster for adjusting the electrical downtilt angles of the antennas is provided for each antenna. Thus, even if at least one of the first antenna and the second antenna shares the same antenna panel with other antennas, the coverage range of the signals sent by the two antennas can be adjusted by adjusting the electrical downtilt angles, thereby supporting improved communication flexibility while saving antenna panel resources.

For example, the signal received by the first antenna is recorded as signal 3, and the signal received by the second antenna is recorded as signal 4. Then, the wavelength of signal 3 and signal 4 is the same, and the data carried is the same. Thereafter, the first regulator is used to process signal 3 (corresponding to the above-mentioned first processing, for example, phase shift processing), and the second regulator is used to process signal 4 (corresponding to the above-mentioned second processing, for example, phase shift processing), and the splitter can realize the function of a combiner in the signal receiving process, that is, it is used to combine signal 3 and signal 4 processed by the regulator and send them to the radio frequency unit.

The antenna system of the fourth aspect and its various possible implementations is also applicable to the signal receiving process. For example, the signal received by the first antenna is recorded as signal 1, and the signal received by the second antenna is recorded as signal 2. Then, the wavelength of signal 1 and signal 2 are the same, and the data carried is the same. Thereafter, the first regulator is used to process signal 1 (corresponding to the above-mentioned first processing, for example, phase shift processing), and the second regulator is used to process signal 2 (corresponding to the above-mentioned second processing, for example, phase shift processing), and the splitter can realize the function of a combiner in the signal receiving process, that is, it is used to combine signal 1 and signal 2 processed by the regulator and send them to the radio frequency unit. It should be noted that the signal receiving process listed above is only an exemplary description, and the present application is not particularly limited thereto. The signal receiving process is the inverse process of the signal sending process. In order to avoid redundancy, its detailed description is omitted.

[0128] In a fifth aspect, an antenna system is provided, including a first antenna, a second antenna, a radio frequency unit, a first adjuster, and a second adjuster, wherein the first antenna can rotate around a first rotation axis to adjust a first mechanical azimuth angle of the first antenna, and the second antenna can rotate around a second rotation axis to adjust a second mechanical azimuth angle of the second antenna, wherein the radio frequency unit is used to generate a first radio frequency signal and a second radio frequency signal to be sent, wherein the first radio frequency signal and the second radio frequency signal have the same wavelength, carry the same data as the first radio frequency signal and the second radio frequency signal, and have the same target azimuth angle as the second radio frequency signal; the first adjuster is used to perform a first processing on the first radio frequency signal to adjust a first electrical azimuth angle of the first radio frequency signal, wherein the first electrical azimuth angle is determined based on the target azimuth angle and the first mechanical azimuth angle; the second adjuster is used to perform a second processing on the second radio frequency signal to adjust a second electrical azimuth angle of the second sub-radio frequency signal, wherein the second electrical azimuth angle is determined based on the target azimuth angle and the second mechanical azimuth angle; the first antenna is used to transmit the first sub-radio frequency signal after the first processing; and the first antenna is used to transmit the second sub-radio frequency signal after the second processing.

[0129] According to the solution provided in the present application, two antennas for sending signals with the same wavelength and carrying the same data are independently configured (specifically, the mechanical azimuth angles of the antennas can be independently adjusted), and an adjuster for adjusting the electrical azimuth angle of the antenna is provided for each antenna. Therefore, even if at least one of the first antenna and the second antenna shares the same antenna panel with other antennas, the coverage range of the signals sent by the two antennas can be adjusted by adjusting the electrical azimuth angle, thereby supporting improved communication flexibility while saving antenna panel resources.

[0130] As an example but not limitation, the antenna system further includes a first sensor for detecting the first mechanical azimuth angle, and the antenna system further includes a second sensor for detecting the second mechanical azimuth angle.

[0131] In one implementation, the antenna system further includes a third antenna configured on the first antenna.

[0132] In another implementation, the antenna system further includes a fourth antenna configured on the second antenna.

[0133] For example, the third antenna is an active antenna, and the fourth antenna is an active antenna.

[0134] Furthermore, the first antenna is a passive antenna, and the second antenna is a passive antenna.

[0135] For another example, the third antenna is a passive antenna, and the fourth antenna is a passive antenna.

[0136] Furthermore, the first antenna is an active antenna, and the second antenna is an active antenna.

[0137] In the present application, the first rotation axis and the second rotation axis are arranged in parallel.

[0138] Furthermore, the first rotation axis may be disposed at any position such as the edge or the center of the first antenna.

[0139] The second rotation axis can be configured at any position such as the edge or center of the first antenna, and is not particularly limited in the present application.

[0140] In the present application, the first regulator may be a circuit or a mechanical unit having a phase adjustment function.

[0141] In a possible implementation manner, the first regulator may also adjust the amplitude of the first radio frequency signal.

[0142] By way of example and not limitation, the first regulator includes a splitter and a phase shifter.

[0143] That is, the first radio frequency signal may be divided into two signals by a splitter, and the phase difference between the two signals may be adjusted by a phase shifter, thereby achieving adjustment of the first electrical azimuth.

[0144] Similarly, the second regulator may be a circuit or a mechanical unit having a phase adjustment function.

[0145] In a possible implementation manner, the second regulator may also adjust the amplitude of the second radio frequency signal.

[0146] For example, the second regulator includes the splitter and a phase shifter.

[0147] That is, the second radio frequency signal may be divided into two signals by a splitter, and the phase difference between the two signals may be adjusted by a phase shifter, thereby achieving adjustment of the second electrical azimuth.

[0148] Optionally, the antenna system also includes a first controller and a second controller, the first controller being used to control the first regulator to perform the first processing according to the target azimuth angle corresponding to the first RF signal and the first mechanical azimuth angle, and the second controller being used to control the second regulator to perform the second processing according to the target azimuth angle corresponding to the first RF signal and the second mechanical azimuth angle.

[0149] In another implementation, the first controller may be configured or integrated in the first regulator, or the second controller may be configured or integrated in the second regulator.

[0150] Optionally, when the first mechanical azimuth angle and the second mechanical azimuth angle are 0, the first antenna and the second antenna are coplanar.

[0151] In the present application, there is a phase difference P between the first RF signal and the second RF signal generated by the RF unit.

[0152] Thus, by adjusting the phase difference between the first RF signal and the second RF signal, the time interval between the sending times of the first RF signal and the second RF signal can be adjusted, thereby compensating for the deviation in the transmission time of the first RF signal and the second RF signal from being sent from the antenna to reaching the receiving end due to the different azimuth angles of the first antenna and the second antenna, and enabling the receiving end to synchronously receive the first RF signal and the second RF signal, thereby improving the accuracy and reliability of communication.

[0153] In one implementation, the phase difference P is determined based on first information, where the first information includes at least one of the following: the wavelength λ of the first radio frequency signal, the first mechanical azimuth The second mechanical azimuth The first electrical azimuth angle θ1 and the second electrical azimuth angle θ2.

[0154] Furthermore, when the first antenna and the second antenna are arranged horizontally in left and right directions, the first information also includes: a length M of the target antenna, and a distance L between the first antenna and the second antenna in the horizontal direction when the first mechanical azimuth angle and the second mechanical azimuth angle are 0, wherein the target antenna is the one of the first antenna and the second antenna that is closer to the target azimuth angle in the horizontal direction.

[0155] Optionally, the phase difference P is determined according to the following formula:

[0156]

[0157] In addition, if the first antenna and the second antenna are not coplanar when the first mechanical azimuth angle and the second mechanical azimuth angle are 0, the first information also includes a distance N between the first antenna and the second antenna in a second direction when the first mechanical azimuth angle and the second mechanical azimuth angle are 0, and the second direction is perpendicular to the plane where the first antenna is located when the first mechanical azimuth angle is 0.

[0158] It should be understood that the antenna system of the fifth aspect and its various possible implementations is described above by taking the functions of each component when sending a signal as an example, but the present application is not limited thereto. The antenna system of the fifth aspect and its various possible implementations is also applicable to the signal receiving process. For example, the signal received by the first antenna is recorded as signal 3, and the signal received by the second antenna is recorded as signal 4. Then, the wavelength of signal 3 and signal 4 is the same, and the data carried is the same. Thereafter, the first regulator is used to process signal 3 (corresponding to the above-mentioned first processing, for example, phase shift processing), and the second regulator is used to process signal 4 (corresponding to the above-mentioned second processing, for example, phase shift processing), and the splitter can realize the function of a combiner in the signal receiving process, that is, it is used to combine signal 3 and signal 4 processed by the regulator and send them to the radio frequency unit. It should be noted that the signal receiving process listed above is only an exemplary description, and the present application is not particularly limited thereto. The signal receiving process is the inverse process of the signal sending process. In order to avoid redundancy, its detailed description is omitted.

[0160] According to the solution provided in the present application, by independently configuring two antennas for sending signals with the same wavelength and carrying the same data (specifically, the mechanical azimuth angles of the antennas can be independently adjusted), the electrical azimuth angle of the first antenna is adjusted by the phase difference between the first RF signal and the second RF signal, and the electrical azimuth angle of the second antenna is adjusted by the phase difference between the third RF signal and the fourth RF signal. Therefore, even if at least one of the first antenna and the second antenna shares the same antenna panel with other antennas, the coverage range of the signals sent by the two antennas can be adjusted by adjusting the electrical azimuth angle, thereby supporting the improvement of communication flexibility while saving antenna panel resources.

[0161] As an example but not limitation, the antenna system further includes a first sensor for detecting the first mechanical azimuth angle, and the antenna system further includes a second sensor for detecting the second mechanical azimuth angle.

[0170] The second rotation axis can be configured at any position such as the edge or center of the first antenna, and is not particularly limited in the present application.

[0171] Optionally, when the first mechanical azimuth angle and the second mechanical azimuth angle are 0, the first antenna and the second antenna are coplanar.

[0172] Optionally, there is a third phase difference P between the fifth RF signal and the sixth RF signal, the fifth RF signal is the one with the later phase between the first RF signal and the second RF signal, and the sixth RF signal is the one with the later phase between the third RF signal and the fourth RF signal.

Then, the wavelength of signal 3 and signal 4 are the same, and the data they carry are the same. Thereafter, the first regulator is used to process signal 3 (corresponding to the above-mentioned first processing, for example, phase shift processing), and the second regulator is used to process signal 4 (corresponding to the above-mentioned second processing, for example, phase shift processing). In addition, the splitter can realize the function of a combiner in the signal receiving process, that is, it is used to combine signal 3 and signal 4 processed by the regulator and send them to the radio frequency unit.

[0196] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0197] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, fifth generation (5G) system or new radio (NR), etc.

[0198] The antenna system provided in the present application can be used in network equipment, and in particular, can be suitable for scenarios where multiple (two or more) antennas (or antenna arrays) for transmitting different data (or belonging to different operators) need to be configured on the same panel.

[0199] The network device in the embodiment of the present application can be a device for communicating with a terminal device. The network device can be a base station (Base Transceiver Station, BTS) in a global system of mobile communications (Global System of Mobile communication, GSM) system or code division multiple access (Code Division Multiple Access, CDMA), or a base station (NodeB, NB) in a wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, or an evolved base station (Evolutional NodeB, eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (Cloud Radio Access Network, CRAN) scenario, or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a future 5G network, or a network device in a future evolved PLMN network, etc., and the embodiments of the present application are not limited.

[0200] The antenna system of the present application includes multiple (or at least two) antennas.

[0201] In the present application, the antenna may also be referred to as an antenna panel or an antenna array, that is, the antenna is formed in a plane shape (or a plate shape).

[0202] In the present application, the configuration relationship between any two antennas among the multiple antennas may be the same or similar. For ease of understanding and explanation, the configuration relationship between antenna #A and antenna #B among the multiple antennas is taken as an example for explanation.

[0203] The antenna #A and antenna #B are configured in such a way that the mechanical downtilt angles can be independently adjusted.

[0204] Specifically, antenna #A and antenna #B can rotate around different rotation axes. For ease of understanding and explanation, the rotation axis of antenna #A is recorded as rotation axis #a, and the rotation axis of antenna #B is recorded as rotation axis #b. In one implementation, the rotation axis #a and the rotation axis #b can extend in the horizontal direction, so that by adjusting the rotation angles of antenna #A and antenna #B around their respective rotation axes, the downtilt angles (specifically, the mechanical downtilt angles) of antenna #A and antenna #B can be adjusted. It should be noted that Figures 1 to 3 The positional relationship between the rotation axis #a and the antenna #A is only an exemplary description, and the present application is not limited thereto. Those skilled in the art can arbitrarily set the positional relationship between the rotation axis #a and the antenna #A according to actual needs, as long as it can ensure that the antenna #A can rotate around the rotation axis #a. Similarly, Figures 1 to 3 The listed positional relationship between the rotation axis #b and the antenna #B is only an example description, and the present application is not limited thereto. Those skilled in the art can arbitrarily set the positional relationship between the rotation axis #b and the antenna #B according to actual needs, as long as it can ensure that the antenna #B can rotate around the rotation axis #b.

[0205] In one implementation, Figure 1 As shown, the antenna #A and antenna #B can be configured up and down.

[0206] In the present application, "up and down configuration" can be understood as up and down configuration in the vertical direction (or, perpendicular direction or gravity direction).

[0207] And, for example, the rotation axis #a and the rotation axis #b are coplanar in the vertical direction, or in other words, Figure 2 As shown, when the mechanical downtilt angles of antenna #A and antenna #B are not 0, antenna #A and antenna #B are coplanar.

[0208] It should be noted that, in the present application, an angle of 0 can be understood as an angle of 0°.

[0209] For another example, the rotation axis #a and the rotation axis #b are not coplanar in the vertical direction, or in other words, Figure 3 As shown, when the mechanical downtilt angle of antenna #A and antenna #B is not 0, antenna #A and antenna #B are not coplanar, that is, when the mechanical downtilt angle of antenna #A and antenna #B is not 0, there is a gap between the plane where antenna #A is located and the plane where antenna #B is located, denoted as: N.

[0210] In another implementation, Figure 4 As shown, the antenna #A and the antenna #B can be configured left and right.

[0211] In the present application, "lateral arrangement" can be understood as arrangement in parallel in the horizontal direction.

[0212] And, for example, the rotation axis #a and the rotation axis #b are coplanar in the horizontal direction, or in other words, Figure 5 As shown, when the mechanical downtilt angles of antenna #A and antenna #B are the same, antenna #A and antenna #B are coplanar.

[0213] For another example, the rotation axis #a and the rotation axis #b are not coplanar in the horizontal direction, or in other words, Figure 6 As shown, when the mechanical downtilt angles of antenna #A and antenna #B are the same, antenna #A and antenna #B are not coplanar, that is, when the mechanical downtilt angles of antenna #A and antenna #B are the same, there is a gap between the plane where antenna #A is located and the plane where antenna #B is located, denoted as: T.

[0214] It should be understood that the configuration of antenna #A and antenna #B listed above is only an example, and the present application is not limited thereto. Figure 7 As shown in FIG. 1 , when antenna #A and antenna #B are arranged vertically, the positions of antenna #A and antenna #B in the horizontal direction may be offset. Figure 8 As shown, when antenna #A and antenna #B are arranged on the left and right, the positions of antenna #A and antenna #B in the vertical direction may be offset.

[0215] In a possible implementation, antenna #A and antenna #B are used to transmit the same data (denoted as data #1).

[0216] In another possible implementation, the antenna #A and the antenna #B are used to transmit signals with the same wavelength.

[0217] In a possible implementation, at least one of antenna #A and antenna #B may be configured with other antennas.

[0218] For example, Fig. 9 As shown, antenna #C is configured on one of antenna #A and antenna #B (for example, antenna #A), wherein the data (denoted as data #2) transmitted by antenna #C is different from data #1.

[0219] For example, Fig.10 As shown, antenna #C is configured on antenna #A, wherein the data (referred to as data #2) transmitted by antenna #C is different from data #1. Furthermore, antenna #D is configured on antenna #B, wherein the data (referred to as data #3) transmitted by antenna #D is different from data #1. Furthermore, data #2 and data #3 may be the same or different, which is not particularly limited in the present application.

[0220] In one implementation, the antenna #A and the antenna #B may be passive antennas.

[0221] In this case, the antenna #C and / or antenna #D may be an active antenna, or an active antenna unit (AAU). The AAU combines the active units related to the transceiver (amplifier, digital-to-analog and analog-to-digital converters, etc.) with the passive antenna to form an integrated unit.

[0222] Alternatively, the antenna #C and / or antenna #D may be a passive antenna.

[0223] In another implementation, the antenna #A and the antenna #B may be active antennas, in which case the antenna #C and / or the antenna #D may be active antennas, or the antenna #C and / or the antenna #D may be passive antennas.

[0224] In addition, in the present application, the coverage ranges of the signals sent by antenna #A and antenna #B are the same (or approximately the same), that is, the target downtilt angles of antenna #A and antenna #B are the same.

[0225] The following describes in detail the antenna system with the above configuration and a solution that enables the antennas to have the same target downtilt angle.

[0226] Fig.11 Schematic diagram of an example of the antenna system of the present application. Fig.11 As shown, the antenna system includes: a radio frequency unit 110, a splitter 120, a regulator 130 (i.e., an example of a first regulator), a regulator 140 (i.e., an example of a second regulator), an antenna 150 (i.e., an example of a first antenna), and an antenna 160 (i.e., an example of a second antenna).

[0227] The functions and structures of the above components are described in detail below.

[0228] A. Antenna

[0229] The antenna system includes at least two antennas, wherein the configuration relationship between any two of the at least two antennas is similar to the configuration relationship between antenna #A and antenna #B mentioned above. Here, for ease of understanding, the case where the antenna system includes two antennas, namely, antenna 150 and antenna 160, is described.

[0230] The mechanical downtilt angles of the antenna 150 and the antenna 160 may be different.

[0231] For example, when the antenna 150 is a passive antenna, the mechanical downtilt angle of the antenna 150 may be determined according to the signal coverage requirement of an active antenna configured on the antenna 150 .

[0232] For another example, when the antenna 160 is a passive antenna, the mechanical downtilt angle of the antenna 160 may be determined according to a signal coverage requirement of an active antenna configured on the antenna 160 .

[0233] Furthermore, in the present application, the data carried by the signal transmitted by the antenna 150 and the signal transmitted by the antenna 160 are the same, and the wavelengths of the signals are the same, and the target downtilt angles of the antenna 150 and the antenna 160 are the same.

[0234] In the following, for ease of understanding and description, the target downtilt angles of the antenna 150 and the antenna 160 are denoted as δ.

[0235] B. RF unit 110

[0236] The RF unit 110 is used to generate a RF signal (denoted as signal #A), wherein the RF unit may be a remote radio unit (RRU), and the process of the RF unit generating the RF signal may be similar to the prior art, and a detailed description thereof is omitted here to avoid redundancy.

[0237] In addition, the RF unit 110 further includes an output terminal for outputting the signal #A.

[0238] C. Splitter 120

[0239] The input end of the splitter 120 is connected to the output end of the RF unit 110, and is used to obtain the signal #A from the RF unit 110, and split the signal #A to generate the signal #B and the signal #C. The process of the splitter splitting the signal can be similar to the prior art, and the detailed description is omitted here to avoid redundancy. The power of the signal #B and the signal #C can be the same or different, which is not particularly limited in this application.

[0240] It should be noted that when the antenna system includes K antennas (K≥3), the splitter 120 can split the signal #A into K signals, each signal corresponding to one antenna, that is, one signal is transmitted through its corresponding antenna.

[0241] For ease of understanding, the following description will take the case where signal #B is sent via antenna 150 and signal #C is sent via antenna 160 as an example.

[0242] Furthermore, the splitter 120 further includes two (ie, when K=2) output ports, one of which is used to output a signal #B, and the other is used to output a signal #C.

[0243] D. Regulator

[0244] The antenna system includes at least two regulators. Specifically, the number of the regulators is the same as the number of antennas, or in other words, at least two regulators correspond to at least two antennas one-to-one, and each regulator is used to process the signal sent by its corresponding antenna. Here, for ease of understanding, the antenna system includes two regulators, namely, regulator 130 (i.e., an example of a first regulator) and regulator 140 (i.e., an example of a second regulator).

[0245] For ease of understanding, the following description will take as an example a case where the regulator 130 is used to process a signal (i.e., signal #B) sent via the antenna 150 and the regulator 140 is used to process a signal (i.e., signal #C) sent via the antenna 160.

[0246] In this case, the input port of the regulator 130 is connected to the output port of the splitter for outputting the signal #B, and the input port of the regulator 140 is connected to the output port of the splitter for outputting the signal #C.

[0247] In the present application, the regulator 130 is used to adjust the mechanical downtilt angle (i.e., the first mechanical downtilt angle) of the antenna 150 according to the target downtilt angle δ of the antenna 150 (or the signal #B). ), adjust the electrical downtilt angle (i.e., an example of the first electrical downtilt angle θ1) of antenna 150 (or signal #B).

[0248] As an example and not limitation, the adjuster 130 may modulate the electrical downtilt angle of the antenna 150 to satisfy the following formula:

[0249]

[0250] In one possible implementation, the regulator 130 may include a splitter and a phase regulator, wherein the splitter is used to split the signal #B to divide the signal #B into two (or multiple) signals, and the phase regulator is used to adjust the phase difference between the two (or multiple) signals, thereby achieving the adjustment of the above-mentioned electrical downtilt angle, wherein the method and process of adjusting the electrical downtilt angle by adjusting the phase difference between the signals may be similar to the prior art, and here, in order to avoid redundancy, its detailed description is omitted.

[0251] As an example but not limitation, the antenna system may further include a controller 170 (ie, an example of the first controller 170), the controller 170 being configured to obtain the target downtilt angle δ and the mechanical downtilt angle Then, according to the target downtilt angle δ and the mechanical downtilt angle The processing parameters of the regulator 130 are controlled to implement the above-mentioned electrical downtilt angle adjustment process.

[0252] For example, the controller 170 may include but is not limited to a microcontroller unit (MCU).

[0253] In one implementation, the target downtilt angle δ and the mechanical downtilt angle This may be input to the regulator 130 or the controller 170 by an administrator or operator.

[0254] In another implementation, the antenna system may further include a rotation angle sensor 190, which is used to detect the mechanical downtilt angle. Furthermore, the regulator 130 or the controller 170 may be connected to the rotation angle sensor 190, so as to obtain the mechanical downtilt angle from the rotation angle sensor 190. information.

[0255] Similarly, the adjuster 140 is used to adjust the mechanical downtilt angle (i.e., the second mechanical downtilt angle) of the antenna 160 according to the target downtilt angle δ of the antenna 160 (or the signal #C). ), adjusting the electrical downtilt angle (i.e., an example of the second electrical downtilt angle θ2) of the antenna 160 (or the signal #C)

[0256] The adjuster 140 can modulate the electrical downtilt angle of the antenna 160 to satisfy the following formula:

[0257]

[0258] As an example but not limitation, the antenna system may further include a controller 180 (ie, an example of the second controller 180), the controller 180 being configured to obtain the target downtilt angle δ and the mechanical downtilt angle Then, according to the target downtilt angle δ and the mechanical downtilt angle The processing parameters of the regulator 140 are controlled to implement the above-mentioned electrical downtilt angle adjustment process.

[0259] For example, the controller 180 may include but is not limited to a microcontroller unit (MCU).

[0260] In one implementation, the target downtilt angle δ and the mechanical downtilt angle This may be input to the regulator 140 or the controller 180 by an administrator or operator.

[0261] In another implementation, the antenna system may further include a rotation angle sensor 195, which is used to detect the mechanical downtilt angle. Furthermore, the regulator 140 or the controller 180 may be connected to the rotation angle sensor 195 so as to obtain the mechanical downtilt angle from the rotation angle sensor 195. information.

[0262] Furthermore, the regulator 130 includes an output port for outputting the signal #B after the electrical downtilt angle adjustment process.

[0263] The regulator 140 includes an output port for outputting the signal #C after the electrical downtilt angle adjustment process.

[0264] The input port of the antenna 150 is connected to the output port of the adjuster 130, so that the signal #B after the electrical downtilt angle adjustment process can be obtained from the adjuster 130 and the signal #B can be transmitted.

[0265] The input port of the antenna 160 is connected to the output port of the adjuster 140, so that the signal #C after the electrical downtilt angle adjustment process can be obtained from the adjuster 140 and the signal #C can be transmitted.

[0266] The antenna system provided by the present application can be effectively applied to the situation where two (or more) antennas (for example, an active antenna and a passive antenna) are configured on the same panel. In the prior art, when two antennas are configured on the same antenna panel, different downtilt angles cannot be provided for the two antennas. Similarly, in the present application, one of the antennas (for example, a passive antenna) can be divided into two parts that can independently adjust the mechanical downtilt angle, and the mechanical downtilt angle of the passive antenna can be determined according to the requirements of the active antenna for the mechanical downtilt angle, and by setting a regulator, the electrical downtilt angle of the passive antenna can be adjusted. Therefore, even if the mechanical downtilt angle of the passive antenna cannot meet the coverage requirements of the signal sent by the passive antenna, the electrical downtilt angle of the passive antenna can still be adjusted to meet the coverage requirements of the signal sent by the passive antenna.

[0267] In the present application, since antenna 150 and antenna 160 are configured at different positions and their mechanical downtilt angles are different, signals sent from antenna 150 and antenna 160 may not reach the same position at the same time, thereby affecting the communication quality.

[0268] In this regard, in the present application, a regulator 197 (i.e., an example of a third regulator) may be further provided, and the regulator 197 is connected to the splitter and is used to adjust the signal #B and the signal #C output from the splitter to adjust the phase difference between the signal #B and the signal #C, so as to enable the signals respectively sent from the antenna 150 and the antenna 160 to reach the same target at the same time, or in other words, to enable the time difference between the signals respectively sent from the antenna 150 and the antenna 160 to reach the same target to be within a preset range. Fig.12 A schematic diagram of an antenna system having the above-mentioned regulator 197 is shown, and Fig.11 The difference between the antenna system shown is that the output port of the splitter is connected to the regulator 197, and the two output ports of the regulator 197 are used to output the phase-adjusted signal #B and signal #C respectively.

[0269] In the present application, the phase difference between signal #B and signal #C may be determined based on the radio frequency path difference D between signal #B and signal #C (or, between antenna 150 and antenna 160).

[0270] For example, if antenna 150 and antenna 160 are at a downtilt angle of 0, Fig.13 Configuration mode, that is, Fig.13As shown, if antenna 150 is configured above antenna 160, the horizontal distance between antenna 150 and antenna 160 when the downtilt angle is 0 is N, the vertical distance is L, and the length of antenna 160 is M, then Fig.14 The mechanical downtilt angle of antenna 150 is shown as The mechanical downtilt angle of antenna 160 is When , the RF path difference between signal #B and signal #C is D.

[0271] That is, the path difference D satisfies the following formula:

[0272] D=AB·cosδ=(N1+N2+N)cosδ

[0273] N1=L·tanδ

[0274] N2=M·tanδ

[0275] Wherein δ represents the target downtilt angle of antenna 150 and antenna 160 (or, signal #B and signal #C).

[0276] Therefore, the phase difference P between signal #C and signal #B can be determined according to the wave path difference D, that is, the phase difference P satisfies the following formula:

[0277] P=2π*D / λ

[0278] Here, λ represents the wavelength of signal #C (or signal #B).

[0279] It should be understood that if the antenna 150 and the antenna 160 are coplanar when the downtilt angle is 0, then the above N=0.

[0280] In addition, the distance L between the antenna 150 and the antenna 160 in the vertical direction when the downtilt angle is 0 may be 0 or not, and those skilled in the art may set or change it as required according to actual needs.

[0281] As an example and not limitation, the regulator 197 may perform phase adjustment based on at least one of the following information:

[0282] The wavelength λ of signal #A (or signal #B or signal #C), the mechanical downtilt angle Mechanical down tilt Electrical downtilt angle θ1 and electrical downtilt angle θ2.

[0283] For example, when the antenna 150 and the antenna 160 are arranged vertically in the direction of gravity (ie, as shown in FIG. Figure 1 and Figure 2When the configuration is configured as shown, the distance between the antenna located below (e.g., antenna 160) and the target location is shorter, so the phase of the signal (i.e., signal #C) emitted by antenna 160 can be adjusted so that the phase difference between signal #C and signal #B satisfies the following formula:

[0284]

[0285] Wherein, M represents the length of the antenna 160, and L represents the distance between the antenna 150 and the antenna 160 when the antenna 160 and the antenna 150 are vertically configured (ie, the mechanical downtilt angle is 0).

[0286] For another example, when antenna 150 and antenna 160 are Figure 3 When configuring in this manner, when adjusting the phase of signal #C, the distance N between antenna 160 and antenna 150 in the horizontal direction when the mechanical downtilt angle is 0 (or when the antenna is configured vertically) may also be considered.

[0287] Fig.15 is a schematic diagram of another example of the antenna system of the present application, and Fig.11 The difference between the antenna system shown is that the radio frequency unit 110 can generate multiple signals, for example, the above-mentioned signal #B and signal #C, so there is no need to configure a splitter.

[0288] In one possible implementation, Fig.15 In the antenna system shown, the RF unit 110 generates the signal #B and the signal #C even if the signal #B has the above-mentioned phase difference P between the signal #B and the signal #C.

[0289] Fig.16 is a schematic diagram of another example of the antenna system of the present application, such as Fig.16 As shown, the antenna system includes: a radio frequency unit 210, an antenna 220 (ie, an example of a first antenna), and an antenna 230 (ie, an example of a second antenna).

[0290] The functions and structures of the above components are described in detail below.

[0291] A. Antenna

[0292] The antenna system includes at least two antennas, wherein the configuration relationship between any two of the at least two antennas is similar to the configuration relationship between the above-mentioned antenna #A and antenna #B. Here, for ease of understanding, the case where the antenna system includes two antennas, namely, antenna 220 and antenna 230, is described.

[0293] The mechanical downtilt angles of the antenna 220 and the antenna 230 may be different.

[0294] For example, when the antenna 220 is a passive antenna, the mechanical downtilt angle of the antenna 220 may be determined according to the signal coverage requirement of an active antenna configured on the antenna 220 .

[0295] For another example, when the antenna 230 is a passive antenna, the mechanical downtilt angle of the antenna 230 may be determined according to a signal coverage requirement of an active antenna configured on the antenna 230 .

[0296] Furthermore, in the present application, the signal transmitted by the antenna 220 and the signal transmitted by the antenna 230 carry the same data, and the wavelengths of the signals are the same, and the target downtilt angles of the antenna 220 and the antenna 230 are the same.

[0297] In the following, for ease of understanding and description, the target downtilt angles of the antenna 220 and the antenna 230 are denoted as δ.

[0298] B. RF unit 210

[0299] The RF unit 210 is used to generate 2K RF signals, where K is the number of antennas, wherein the 2K RF signals are divided into K signal groups, each signal group includes 2 RF signals, and the K signal groups correspond one-to-one to the K antennas, and the signals in each signal group are sent through the antenna corresponding to the signal group.

[0300] Below, for ease of understanding, the case where K=2 is used as an example for explanation. In this case, the RF unit 210 is used to generate 4 RF signals (denoted as signal #1, signal #2, signal #3 and signal #4), wherein signal #1 and signal #2 constitute a signal group, and the signals in the signal group are sent through antenna 220; signal #3 and signal #4 constitute a signal group, and the signals in the signal group are sent through antenna 230.

[0301] Furthermore, there is a phase difference between signal #1 and signal #2, and the phase difference is used to adjust the electrical downtilt angle of antenna 220. Assume that the target downtilt angle δ of antenna 220 and the mechanical downtilt angle of antenna 220 (i.e., the first mechanical downtilt angle ), the electrical downtilt angle θ1 of the antenna 220 determined based on the phase difference between the signal #1 and the signal #2 satisfies the following formula:

[0302]

[0303] Similarly, there is a phase difference between signal #3 and signal #4, and the phase difference is used to adjust the electrical downtilt angle of antenna 230. Assume that the target downtilt angle δ of antenna 220 and the mechanical downtilt angle of antenna 230 (i.e., the first mechanical downtilt angle ), the electrical downtilt angle θ2 of the antenna 230 determined based on the phase difference between the signal #3 and the signal #4 satisfies the following formula:

[0304]

[0305] In the present application, since antenna 220 and antenna 230 are configured at different positions and their mechanical downtilt angles are different, signals sent from antenna 220 and antenna 230 may not reach the same position at the same time, thereby affecting the communication quality.

[0306] In this regard, in the present application, the phase difference between the phase lag between signal #1 and signal #2 (set as signal #1) and the phase lag between signal #3 and signal #4 (set as signal #3) can also be adjusted, so that the signals sent from antenna 220 and antenna 230 can reach the same target at the same time, or in other words, the time difference between the signals sent from antenna 220 and antenna 230 reaching the same target is within a preset range.

[0307] Among them, the method and process for determining the phase difference between the phase-lagging party (set as signal #3) between signal #3 and signal #4 can be similar to the method and process for determining the above-mentioned phase difference P. Here, in order to avoid repetition, its detailed description is omitted.

[0308] The antenna system provided in the present application is also applicable to a signal receiving process, wherein the signal receiving process is the inverse process of the signal sending process. Here, in order to avoid redundancy, a detailed description is omitted.

[0309] The above-mentioned adjustment process for the downtilt angle is also applicable to the adjustment process for the azimuth angle. Fig.17 A schematic diagram showing an example of the configuration of the azimuth angle of the antenna of the present application, that is, Figure 2 The configuration of the downtilt angle shown is different in that Fig.17 In the figure, the direction of the rotation axis is the vertical direction (or the direction of gravity).

[0310] It should be understood that Fig.17 The antenna configuration shown is only an example, and the present application is not limited thereto. Multiple antennas with different azimuth angles may not be coplanar when the mechanical direction angle is 0.

[0311] Furthermore, the process of determining and adjusting the electrical azimuth angle may be similar to the process of determining and adjusting the electrical downtilt angle described above, and a detailed description thereof is omitted here to avoid redundancy.

[0312] That is, when the same signal (or data) is sent through antennas with different mechanical azimuth angles, the method for adjusting the electrical azimuth angles of the different antennas and the method for adjusting the phase difference of the signals sent by the different antennas are the same as those described above. Figures 11 to 16The processing procedures shown are similar, and the detailed description is omitted here to avoid redundancy.
