Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an antenna device and a base station. Background Art

[0002] In a massive MIMO (MM) antenna system, multiple radiation unit groups of antenna devices form corresponding channels. Multiple channels do not affect or interfere with each other, and radio wave signals can be transmitted through multiple channels, thereby realizing spatial diversity of channels. In order to meet the communication needs of multiple terminal devices, the MM system increases the number of channels by increasing the number of radiation unit groups, so that different radiation unit groups can be used to transmit radio wave signals of corresponding terminal devices, and adjust the beam pointing direction of radio wave signals in the time domain and frequency domain for different terminal devices, thereby improving the system coverage and capacity, and greatly improving the transmission rate of radio wave signals in the MM system and the total amount of data that can be transmitted. At the same time, the transmission quality and accuracy of radio wave signals are also greatly improved. However, when increasing the number of radiation unit groups to improve the system coverage and capacity, there is a problem that the beam pointing direction of radio wave signals in the time domain and frequency domain cannot be adjusted for different terminal devices. However, how to improve the coverage of radio electromagnetic wave signals while ensuring that the beam pointing of radio electromagnetic wave signals can be adjusted in time and frequency domains for different terminal devices without increasing the number of radiation unit groups, or how to use an antenna device with fewer radiation unit groups, is a technical problem that needs to be solved urgently. Summary of the invention

[0003] In view of this, an antenna device and a base station are proposed.

[0004] In a first aspect, an embodiment of the present application provides an antenna device, comprising: a plurality of radiation unit groups, at least one phase adjustment unit group and a control unit, wherein the phase adjustment unit group comprises a plurality of phase adjustment units;

[0005] A phase adjustment unit of one phase adjustment unit group is connected to one radiation unit group and the control unit respectively;

[0006] The control unit is used to receive a first control command, and control the first signal path where the first phase adjustment unit corresponding to the first control command and the first radiation unit group connected to the first phase adjustment unit are located to be turned on;

[0007] The first phase adjustment unit is used to adjust the phase of the communication signal corresponding to the target subband between the first radiation unit group and the terminal device;

[0008] The first radiation unit group is used to transmit the communication signal between the terminal device and the target sub-band, and the target sub-band is at least one of the multiple sub-bands corresponding to the working frequency band of the antenna device.

[0009] Through the first aspect, by adjusting the phase adjustment unit of the signal path in each phase adjustment unit group in the antenna device to adjust the beam direction corresponding to the communication signal transmitted by each radiation unit group, while improving the coverage of the radio electromagnetic wave signal, it is ensured that the beam direction of the communication signal can be adjusted in the time domain and frequency domain for different terminal devices. In addition, it is suitable for multi-channel, multi-terminal device, multi-carrier, and multi-standard application scenarios.

[0024] The device parameters also include: device characteristic parameters of the phase shifter.

[0025] Through the fifth possible implementation manner, the phase of the communication signal of the third radiation unit group can be adjusted with the help of a phase shifter to improve the adaptability of the device in different application scenarios.

[0026] In combination with the second possible implementation manner, in a sixth possible implementation manner of the device, the device further includes:

[0027] a power divider connected to the plurality of radiation unit groups, for splitting the communication signal to be transmitted from the transceiver unit into a plurality of communication signals, and sending the communication signals to the corresponding radiation unit groups, and / or

In addition, it is suitable for multi-channel, multi-terminal device, multi-carrier, and multi-standard application scenarios.

[0032] In conjunction with the second aspect, in a first possible implementation of the base station, the baseband processing unit is further configured to send a second control command to the antenna device, thereby improving the accuracy of the multiple expected weights of the determined terminal device.

[0069] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0070] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0071] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0072] The embodiment of the present application provides an antenna device and a base station, which adjusts the beam pointing direction corresponding to the communication signal transmitted by each radiation unit group by adjusting the phase adjustment unit of the signal path in each phase adjustment unit group in the antenna device, while improving the coverage of the radio electromagnetic wave signal, ensuring that the beam pointing direction of the communication signal can be adjusted in the time domain and frequency domain for different terminal devices. In addition, the technical solution provided by the embodiment of the present application is suitable for application scenarios of multi-channel, multi-terminal device, multi-carrier, and multi-standard (such as Long Term Evolution (LET) of universal mobile communication technology, 5GNR (5G New Radio), etc.).

[0073] Figure 1 FIG. 2 shows a schematic diagram of the structure of a base station according to an embodiment of the present application. Figure 1As shown, the base station may include an antenna device 1, a pole 03, a feeder 02, a remote radio unit (RRU) 04, an optical fiber 05, and a baseband unit (BBU) 4. The antenna device 1 is fixed to the pole 03 by an antenna adjustment bracket (not shown in the figure), and the antenna adjustment bracket can adjust the position of the antenna device 1 on the pole 03, the angle between the antenna device 1 and the pole 03, etc. The antenna device 1 is connected to the remote radio unit 04 through the feeder 02, and the remote radio unit 04 is connected to the baseband unit 4 through the optical fiber 05.

[0074] The radio remote unit 04 is used to connect to the baseband processing unit 4 through the optical fiber 05, and processes the signal transmitted by the baseband processing unit 4 through the optical fiber 05 at the remote end and sends it to the antenna device 1, so that the antenna device 1 transmits it to the terminal device 2 (the terminal device 2 can be one or more, Figure 1 Only one terminal device 2 is shown in the figure); and the receiving antenna device 1 receives a receiving signal from the terminal device 2, and transmits the received signal to the baseband processing unit 4 through the optical fiber 05 after processing.

[0075] The baseband processing unit 4 is used to determine the baseband signal that needs to be sent to the terminal device 2, and send the baseband signal to the transceiver unit (transmitter and receiver, referred to as TRX) in the radio frequency remote unit 04. The transceiver unit loads the baseband signal to the sub-band of the working frequency band corresponding to the antenna device 1 and then sends it to the antenna device 1, so that the antenna device 1 radiates the received communication signal into space in the form of electromagnetic waves for reception by the terminal device 2. In addition, the antenna device 2 can receive the received signal from the terminal device 2 loaded on the corresponding sub-band, and send it to the transceiver unit, and the transceiver unit forwards it to the baseband processing unit 4.

[0076] In this embodiment, the terminal device 2 can be called user equipment (UE for short), or a mobile terminal (mobile teminal), a mobile user equipment, etc., and can communicate with one or more core networks via a wireless access network (e.g., RAN, radio access network). The user equipment can be a mobile terminal, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with the wireless access network.

[0077] The following is an explanation of the base station and the antenna device 1 in conjunction with the examples provided in the embodiments of the present application, and describes the implementation method of the technical solution of the present application to solve the technical problem to be solved. It should be noted that the following base station and the antenna device 1 are only examples provided by the present application, and those skilled in the art can set the base station and the antenna device 1 according to actual needs, and the present application does not limit this.

[0078] Figure 2 A schematic diagram of the structure of an antenna device according to an embodiment of the present application is shown. Figure 2 As shown, it includes an antenna device 1 and a terminal device 2. The antenna device 1 can communicate with one or more terminal devices 2. Figure 2 2 shows an example in which an antenna device 1 communicates with multiple terminal devices 2. The antenna device 1 may include multiple radiation unit groups 100, at least one phase adjustment unit group 200, and a control unit 300. The phase adjustment unit group 200 may include multiple phase adjustment units 210. The phase adjustment unit 210 of one phase adjustment unit group 200 is connected to one radiation unit group 100 and the control unit 300, respectively.

[0079] Among them, the phase adjustment unit 210 of one of the phase adjustment unit groups 200 is respectively connected to one of the radiation unit groups 100 and the control unit 300, which may mean that in the layout stage of the antenna device 1, each phase adjustment unit 210 of a phase adjustment unit group 200 is directly or indirectly connected to a radiation unit group 100 and the control unit 300, and a signal path between each phase adjustment unit and a radiation unit group connected thereto is established; wherein direct connection may refer to the phase adjustment unit 210 and the radiation unit group 100 being directly connected through a transmission line, and indirect connection may refer to the phase adjustment unit 210 and the radiation unit group 100 being connected through other devices, such as Figure 3 The dispersion device 212 (i.e., the phase adjustment unit 210) is finally connected to the radiation unit group 100 through the second switch network 330 and the second combining network 340. When the antenna device is in the working stage and the antenna device transmits a communication signal, one of the multiple phase adjustment units of the phase adjustment unit group and the signal path of the radiation unit group connected thereto are turned on to transmit the communication signal, and the other phase adjustment units of the phase adjustment unit group and the signal path of the radiation unit group connected thereto are disconnected.

[0080] Transmitting a communication signal may refer to controlling the sending and / or receiving of a communication signal between the radiation unit group and the terminal device in the form of electromagnetic waves. The communication signal may include a transmission signal sent by the antenna device 1 to the terminal device 2, a reception signal received by the antenna device 1 from the terminal device 2, and other signals that achieve communication with the aid of the radiation unit group 100.

[0081] The antenna device 1 is Figure 2 After the structural schematic diagram shown is laid out and powered on to enter the working state, the first signal path where the corresponding first phase adjustment unit and the first radiation unit group connected to it are located will be controlled to be turned on according to the first control command received, and the other phase adjustment units in the phase adjustment unit group except the first phase adjustment unit will be disconnected from the other signal paths where the first radiation unit group is located, so as to transmit communication signals with the terminal device 2.

[0082] in,

[0083] The control unit 300 is used to receive a first control command and control the conduction of a first signal path where a first phase adjustment unit corresponding to the first control command and a first radiation unit group connected to the first phase adjustment unit are located in the phase adjustment unit group 200. The first phase adjustment unit is one of the multiple phase adjustment units 210 corresponding to the first control command.

[0084] The first phase adjustment unit is used to adjust the phase of the communication signal corresponding to the target sub-band between the first radiation unit group connected to the first phase adjustment unit and the terminal device 2. The first radiation unit group is used to transmit the communication signal with the terminal device 2 on the target sub-band, and the target sub-band is at least one of the multiple sub-bands corresponding to the working frequency band of the antenna device 1.

[0085] Among them, the phase adjustment unit group 200 can be one or more. When there are multiple phase adjustment unit groups 200, the first phase adjustment unit corresponding to the first control command includes: a phase adjustment unit corresponding to the first control command in each phase adjustment unit group 200. For example, assuming that the antenna device includes 4 phase adjustment unit groups C1, C2, C3, and C4, the first phase adjustment unit corresponding to the first control command includes: a phase adjustment unit C1-1 corresponding to the first control command in C1, a phase adjustment unit C2-2 corresponding to the first control command in C2, a phase adjustment unit C3-3 corresponding to the first control command in C3, and a phase adjustment unit C4-4 corresponding to the first control command in C4. The same control unit 300 can be set for multiple phase adjustment unit groups 200, or a control unit 300 can be set for each phase adjustment unit group 200, or multiple phase adjustment unit groups can be further grouped, each group can include at least two phase adjustment unit groups, and each group can be set with a control unit. In this way, the control of multiple phase adjustment unit groups can be achieved by one or more control units.

[0086] In this embodiment, in different communication scenarios, the phases of the communication signals of the plurality of radiation unit groups 100 have the following possible “phase relationships”:

[0087] When one or more terminal devices 2 communicating with the antenna device 1 are within the spatial range of a specific direction of the antenna device 1, in order to improve the transmission effect of the communication signal, all the radiation unit groups 100 can be controlled to transmit the communication signal in the specific direction. At this time, the phases of the communication signals transmitted by multiple radiation unit groups 100 are all target phases (the target phase corresponds to the specific direction), so there is no phase difference between the multiple communication signals. However, in the actual operation of the antenna device 1, without considering the phase adjustment effect of the phase adjustment unit group 200 on the communication signal, the phase of the initial communication signal received by different radiation unit groups 100 without phase adjustment by the phase adjustment unit group 200 may also be different from the target phase, and there may be a phase difference between different initial communication signals (for example, the initial communication signals allocated to different radiation unit groups 100 themselves have a phase difference, or a device that can change the phase of the initial communication signal is connected to the signal path where the radiation unit group 100 is located), and in order to ensure that the phases of the communication signals finally transmitted by multiple radiation unit groups 100 are the same as the target phase, it is necessary to select the first phase adjustment unit in each phase adjustment unit group 100, so that when the first signal path where the first radiation unit group connected to the first phase adjustment unit in the antenna device 1 is located is turned on, the phases of the communication signals transmitted by the multiple radiation unit groups 100 are the same and are the target phase. For example, assuming that the antenna device 1 includes 6 radiation unit groups 100, and the terminal devices 2 communicating with the antenna device 1 are all located in a specific direction and the target phase is 540°, the first phase adjustment unit can be selected according to the phase difference between the phase of the initial communication signal corresponding to each radiation unit group 100 and the target phase, so that when the first signal path where the first radiation unit group connected to the first phase adjustment unit is located is turned on, the phases between the 6 communication signals transmitted by the 6 radiation unit groups 100 are all the target phase of 540°.

[0088] When multiple terminal devices 2 communicating with the antenna device 1 are within the spatial range of multiple specific directions of the antenna device 1, in order to improve the transmission effect of the communication signal, different radiation unit groups 100 can be controlled to transmit the communication signal between the terminal device 2 in a certain direction. At this time, the phase of the communication signal transmitted by the radiation unit group 100 corresponds to the specific direction where the terminal device 2 communicating with it is located. The phases of multiple communication signals are not exactly the same, so there may be a phase difference between the multiple communication signals, that is, there may be a phase difference between multiple communication signals, or there may be no phase difference between some of the communication signals in the multiple signals, and this part of the communication signal without phase difference also has a phase difference with the remaining communication signals. When the phases of multiple communication signals are not exactly the same, part or all of the multiple phases corresponding to the multiple communication signals may be in an arithmetic progression, a geometric progression, etc., which is easy to achieve regular changes in phase, or there may be no regular changes. The following describes the situation of phase difference in conjunction with Example 1 and Example 2.

[0089] Example 1, assuming that the antenna device 1 includes 4 radiation unit groups 100, and the terminal devices 2 communicating with the antenna device 1 are 4 UE1, UE2, UE3, and UE4, which are located in different specific directions and have corresponding target phases of 180°, 360°, 0°, and 540°, respectively. Then, the first phase adjustment unit can be selected according to the phase difference between the phase of the initial communication signal corresponding to each radiation unit group 100 and the target phase of the terminal device 2 communicating with it, so that when the first signal path where the first radiation unit group connected to the first phase adjustment unit is connected is connected, the phases of the 4 communication signals transmitted in the 4 radiation unit groups 100 are the target phases of 180°, 360°, 0°, and 540°, respectively, and there is a phase difference between the communication signals of the 4 radiation unit groups 100. At this time, the target phases 0°, 180°, and 360° change in an arithmetic progression, and there is no change rule between the target phases 540° and 0°, 180°, and 360°. At this time, the transmission signal of each radiation unit group 100 includes four components, namely, the signal loaded on the target subband corresponding to UE1, the signal loaded on the target subband corresponding to UE2, the signal loaded on the target subband corresponding to UE3, and the signal loaded on the target subband corresponding to UE4. Since the phases of the communication signals of the four radiation unit groups 100 are different, since the transmission signal beam with a phase of 180° emitted by a certain radiation unit group 100 points to UE1, UE1 can receive the signal... and so on. Communication signal transmission corresponding to the spatial position of different terminal devices 2 is realized.

[0090] Example 2: Assume that the antenna device 1 includes four radiation unit groups 100, and there are four terminal devices 2 communicating with the antenna device 1, which are located in different specific directions and have corresponding target phases of 180°, 360°, and 540°, respectively. Two radiation unit groups 100 can be selected to communicate with a certain terminal device 2 (such as the terminal device 2 with a target phase of 180°), and the other two radiation unit groups 100 can communicate with the remaining two terminal devices 2, respectively. Then, the first phase adjustment unit can be adjusted according to the phase difference between the phase of the initial communication signal corresponding to each radiation unit group 100 and the target phase of the terminal device 2 with which it communicates. The first signal path of the first radiation unit group connected to the first phase adjustment unit is selected so that when the first signal path of the first radiation unit group is turned on, the phases of the communication signals of two radiation unit groups 100 are 180°, the phases of the communication signals of one radiation unit group 100 are 360°, and the phases of the communication signals of one radiation unit group 100 are 540°. At this time, there is no phase difference between the communication signals of two radiation unit groups 100, and there is a phase difference between the communication signals of the two radiation unit groups 100 with no phase difference and the remaining two radiation unit groups 100, and there is also a phase difference between the communication signals of the remaining two radiation unit groups 100. At this time, there is no change rule between the target phases of 180°, 360°, and 540°.

[0091] In a possible implementation, the first control command and the target subband are based on a plurality of expected weights W of the terminal device 2. ijm The expected weights are used to determine the wave beam characteristics of the communication signal between the terminal device 2 and the antenna device 1. When a communication signal is transmitted using a specific sub-band, the beam characteristics of the radiated electromagnetic wave may include radiation range, radiation angle, and other characteristics that can reflect the radiation of the electromagnetic wave in a spatial range. ijm The beam characteristics of the communication signal between the terminal device 2 and the antenna device 1 can be determined, and then the first phase adjustment unit can be determined according to the beam characteristics, and the first control command can be generated according to the first phase adjustment unit to make the first signal path conductive and the first radiation unit group transmit the communication signal. In addition, the target subband occupied by the communication signal with the terminal device 2 can be determined based on the beam characteristics. In this way, through the multiple expected weights W of the terminal device 2 ijm Determining the first control command and the target subband can make the transmission of the communication signal between the plurality of radiation unit groups 100 and the terminal device 2 more stable and more efficient.

[0092] In a possible implementation, the multiple expected weights W ijmDetermined according to the following parameters: device parameters, multiple sub-bands corresponding to the working frequency band of the antenna device 1, carrier frequency parameters of the reference signal emitted by the radiation unit group 100, signal parameters determined based on the feedback signal of the terminal device 2 for the reference signal, and terminal device state parameters determined based on the feedback signal. The device parameters may include: device characteristic parameters of the multiple radiation unit groups 100, and device characteristic parameters of the multiple phase adjustment units 210. In this way, it can be ensured that the multiple expected weights W of the determined terminal device are ijm The accuracy of the control command and the target subband is ensured to be highly matched with the corresponding terminal device 2 in the subsequent determination.

[0093] Among them, multiple expected weights W of terminal device 2 ijm It can be determined by the baseband processing unit 4 before the antenna device 1 and the terminal device 2 formally transmit the communication signal, using the feedback signal of the terminal device 2 for the reference signal sent by the antenna device 1, and combining with the above other parameters. ijm It can indicate the beam characteristics of the communication signal using the radiation unit group 100 to communicate with the terminal device i (i represents the identification of the corresponding terminal device 2 in the antenna device 1, and the terminal device i is a terminal device 2 communicating with the antenna device 1) through a sub-band j (j represents the identification of the sub-band in the working frequency band) in the working frequency band when the signal path where the corresponding phase adjustment unit to be selected is turned on. The expected weight W ijmThe phase adjustment unit m to be selected corresponding to the radiation unit group 100 may include: a phase adjustment unit 210 in which the signal path in each phase adjustment unit group 200 is turned on when multiple radiation unit groups 100 are transmitting communication signals. The antenna device 1 may include multiple phase adjustment units m to be selected, which are determined according to the number of phase adjustment units 210 in each phase adjustment unit group 200, and the first phase adjustment unit and the second phase adjustment unit described below are selected phase adjustment units from the phase adjustment units m to be selected. And the phase relationship between the communication signals of the multiple radiation unit groups 100 when the signal path between the selected phase adjustment unit and the connected radiation unit group 100 is turned on is different from the phase relationship between the communication signals of the multiple radiation unit groups 100 when the signal path between other selected phase adjustment units and the connected radiation unit groups 100 is turned on, and thus the radiation patterns (radiation patterns) of the antenna device 1 corresponding to the communication signal transmission through the multiple radiation unit groups 100 when the signal paths between different selected phase adjustment units and the connected radiation unit groups 100 are turned on are different. Assuming that the antenna device 1 includes 8 phase adjustment unit groups 200, and each phase adjustment unit group 200 includes 3 phase adjustment units 210, the antenna device 1 can include 8×3=24 selected phase adjustment units, and the radiation pattern of the antenna device 1 is different when the signal path between different selected phase adjustment units and the connected radiation unit group 100 is turned on.

[0094] The device parameters may include device characteristic parameters in the antenna device 1 that can affect the beam characteristics of the communication signal (e.g., device characteristic parameters of the radiation unit group 100, and device characteristic parameters of the phase shifter 500 described below, etc.). The device parameters can reflect the changes that the corresponding device can bring to the power distribution, phase, etc. of the communication signal, and the degree of change, and then use these changes to perform the expected weight W. ijm The signal parameter may refer to information such as the signal strength of the reference signal received by the terminal device 2 determined according to the feedback signal, and the terminal device state parameter may include information indicating the spatial position of the terminal device 1, such as the position of the terminal device 2 and the relative angle between the terminal device 2 and the antenna device 1.

[0095] In this embodiment, the baseband processing unit 4 can determine multiple expected weights of the terminal device 2 before each formal communication signal with the terminal device 2. Among them, the antenna device 1 can be controlled to transmit a reference signal first, so as to determine multiple expected weights of the terminal device 2 based on the carrier frequency parameters of the reference signal, the terminal device state parameters determined based on the feedback signal of the terminal device 2 for the reference signal, the signal parameters determined based on the feedback signal and the device parameters, the multiple sub-bands corresponding to the working frequency band of the antenna device 1, and the device characteristic parameters of the multiple phase adjustment units 210. In this way, the accuracy of the multiple expected weights of the terminal device 2 determined can be improved. The process of determining multiple expected weights of the terminal device 2 by the baseband processing unit 4 refers to the relevant description below and will not be repeated here.

[0096] In a possible implementation, the control unit 300 is further configured to receive a second control command and control the second signal path of the second phase adjustment unit corresponding to the second control command and the second radiation unit group connected to the second phase adjustment unit in the phase adjustment unit group 200 to be turned on. The second control command may come from the baseband processing unit 4.

[0097] The second phase adjustment unit is used to adjust the phase of the reference signal (RS for short) transmitted by the second radiation unit group to the terminal device 2.

[0098] The second radiation unit group is used to transmit the phase-adjusted reference signal to the terminal device 2, and receive a feedback signal from the terminal device 2 in response to the reference signal.

[0099] There may be one or more phase adjustment unit groups 200. When there are multiple phase adjustment unit groups 200, the second phase adjustment unit corresponding to the second control command includes: one phase adjustment unit corresponding to the second control command in each phase adjustment unit group 200. For example, assuming that the antenna device includes two phase adjustment unit groups C1, C2, ..., the second phase adjustment unit corresponding to the second control command includes: one phase adjustment unit in C1 corresponding to the first control command, such as C1-1, one phase adjustment unit in C2 corresponding to the first control command, such as C2-2, ...

[0100] To describe the implementation method of adjusting the phase of the communication signal of the radiation unit group 100 connected to the phase adjustment unit group 200 by using the control unit 300 and the phase adjustment unit group 200, the present application is provided by Figure 3 The phase adjustment unit group 200 and the control unit 300 are described in detail. Those skilled in the art can combine Figure 3 The examples given are set up for the present application and are not limited thereto. Figure 3 A schematic diagram showing the structure of a phase adjustment unit group in an antenna device according to an embodiment of the present application is shown. Figure 4 FIG. 1 is a schematic diagram showing a phase difference variation generated by a phase adjustment unit in an antenna device according to an embodiment of the present application. In a possible implementation, Figure 3 As shown, the multiple phase adjustment units 210 of the phase adjustment unit group 200 may include at least one dispersive device 212 and at least one non-dispersive device 211 (for example Figure 3 The phase adjustment unit group 200 in the figure only shows two dispersive devices and one non-dispersive device). That is, the phase adjustment unit 210 can be a dispersive device 212 or a non-dispersive device 211. The dispersive device 212 can adjust the phase of the communication signal in a dispersive manner. The non-dispersive device 211 can adjust the phase of the communication signal in a non-dispersive manner. The difference between the phase adjustment of the dispersive device 212 and the non-dispersive device 211 is that the former makes the phase difference between the adjusted communication signal of the radiation unit group 100 and the communication signal of at least one other radiation unit group 100 change with the change of frequency, and the latter makes the phase difference between the adjusted communication signal of the radiation unit group 100 and the communication signal of at least one other radiation unit group 100 a fixed value. For example, the non-dispersive device can be a phase shifter.

[0101] In one possible implementation, Figure 3 As shown, when the first phase adjustment unit is a dispersion device 212, when the first signal path is turned on, a phase difference is generated between the communication signal of the first radiation unit group and at least one other radiation unit group 100 among the multiple radiation unit groups 100. The phase difference Δ(f) changes with the frequency according to a preset relationship within the working frequency band. In this way, the phase of the communication signal of the first radiation unit group can be continuously changed to meet the communication requirements of different terminal devices 2.

[0102] In this implementation, Δ(f)=G n (f), n is the number, code, etc. corresponding to the dispersive device 212 or the non-dispersive device 211 in the entire phase adjustment unit group 200. For example, the identifiers of the multiple phase adjustment units 210 (i.e., the dispersive device 212 and the non-dispersive device 211) can be set to 1, 2, 3, etc. in sequence. n (f) represents the function of the phase difference generated by the phase adjustment unit 210 and the frequency. f is the frequency, f∈Band, and Band is the operating frequency band of the antenna device 1. The value of the phase difference Δ(f) within the operating frequency band can change with the frequency according to a linear relationship, such as Figure 4G2, G3, G5 in the figure have different slopes, and the slopes of G2 and G3 are positive (that is, Δ(f) increases with increasing frequency), and the slope of G5 is negative (that is, Δ(f) decreases with increasing frequency). At this time, Δ(f) = G2(f) = k2×f, k2 is the slope of G2; Δ(f) = G3(f) = k3×f, k3 is the slope of G3; Δ(f) = G5(f) = -k5×f, -k5 is the slope of G5. The value of the phase difference Δ(f) within the operating frequency band can change with the change of frequency according to a curve relationship. Alternatively, the value of the phase difference Δ(f) within the operating frequency band can change with the change of frequency according to a non-single change relationship, such as Figure 4 The step-like change shown in G4 in the figure shows that [F1, F2] is the working frequency band of the antenna device, and the values ​​of the slopes k41 and k42 can be the same (e.g. Figure 4 Thus, when the first phase adjustment unit is a dispersion device 212, the phase difference Δ(f) varies with the frequency in the working frequency band according to a preset relationship.

[0103] In a possible implementation, when the first phase adjustment unit is a non-dispersive device 211, when the first signal path is turned on, a phase difference is generated between the communication signals of the first radiation unit group and at least one other radiation unit group 100 among the multiple radiation unit groups 100. The phase difference Δ(f) does not change with the change of frequency within the working frequency band, and the phase difference can be any angle value, such as 0°, 90°, 180°, 540°, etc.

[0104] In this implementation, when the first phase adjustment unit is a non-dispersive device 211, the phase difference Δ(f) may be a specified value, Δ(f)=m, where m represents the phase difference value, such as Figure 4 For the line G1 in FIG. 1 , Δ(f)=G1(f)=180°.

[0105] It should be noted that those skilled in the art can set the dispersive device 212 and the preset relationship corresponding to the dispersive device 212, and the non-dispersive device 211 and the phase difference corresponding to the non-dispersive device 211 according to actual needs, and this application does not impose any restrictions on this.

[0106] In one possible implementation, Figure 3 As shown, the control unit 300 may include a first combining network 320, a first switch network 310, a second combining network 340, a second switch network 330, a control module and a drive module, wherein the control module and the drive module are Figure 3 It is not shown in FIG. Figure 3What is shown in the figure is only an exemplary description of the control unit 300. Those skilled in the art may configure the control unit 300 as required, and this application does not impose any limitation on this.

[0107] The first switch network 310 is respectively connected to one end of at least one dispersive device 212 and at least one non-dispersive device 211 in the same phase adjustment unit group 200, and the first switch network 310 is also connected to the first combining network 320. The second switch network 330 is respectively connected to the other end of at least one dispersive device 212 and at least one non-dispersive device 211 in the same phase adjustment unit group 200, and the second switch network 330 is also connected to the second combining network 340.

[0108] In a possible implementation, the control module is used to receive a first control command (or a second control command), and according to the first control command, the control driving module outputs a driving voltage corresponding to the signal path where the first phase adjustment unit is located, thereby driving the first signal path where the first phase adjustment unit is located to be turned on, and at the same time disconnecting the signal paths connected to other phase adjustment units. Among them, the driving circuit can input a driving voltage that can turn on the signal path where the first phase adjustment unit is located to the first switch network 310 and the second switch network 330 respectively, so that the communication signal can be transmitted in sequence along the turned-on first signal path "first combining network 320, first switch network 310, first phase adjustment unit, second switch network 330, second combining network 340, radiation unit group 100".

[0109] Wherein, the first switch network 310 and the second switch network 330 may respectively include a switching switch connected to each phase adjustment unit, and the switching switch will be closed or turned on under the drive of the driving voltage, so that the signal path where the phase adjustment unit 210 connected to the switching switch is located is turned on. The switching switch can be a triode, a diode, etc. Wherein, when the switching switch is a triode, the voltage in the input triode is adjusted by the driving voltage to control the conduction and cutoff of the triode. When the switching switch is a diode, the conduction and reverse cutoff of the diode can be controlled by adjusting the positive and negative driving voltage of the positive electrode of the input diode. Alternatively, the input voltage of the positive electrode of the diode can be controlled to be a fixed value, and the conduction and reverse cutoff of the diode can be controlled by adjusting the driving voltage of the negative electrode of the input diode. For example, the input voltage value of the negative electrode of the diode is controlled to be 1V, and when the driving voltage of the negative electrode input is 120V, the diode is reversely cutoff, and when the driving voltage of the negative electrode input is 0V, the diode is turned on. Furthermore, the input voltage of the cathode of the diode may be controlled to be a fixed value, and the diode may be controlled to be turned on and off in the reverse direction by adjusting the driving voltage of the anode of the input diode.

[0110] The first combining network 320 can be connected to the switching switches corresponding to each phase adjustment unit 210 in the first switch network 310, respectively, to realize the combining of communication signals between multiple phase adjustment units 210 and the power distributor 400 (the connection and function of the power distributor are described below). That is, it is used to send the communication signal from the power distributor 400 to the first phase adjustment unit through the line between the first combining network 320 and the first switch network 310 corresponding to the first phase adjustment unit; and it is used to send the communication signal from the first phase adjustment unit through the line between the first switch network 310 and the first combining network 320 to the power distributor 400. Similarly, the second combining network 340 can also be connected to the switching switches corresponding to each phase adjustment unit 210 in the second switch network 320, respectively, to realize the combining of communication signals between multiple phase adjustment units 210 and the radiation unit group 100. That is, it is used to send the communication signal from the radiation unit group 100 to the first phase adjustment unit through the line between the second combining network 340 and the second switching network 330 corresponding to the first phase adjustment unit; and it is used to send the communication signal from the first phase adjustment unit via the line between the second switching network 330 and the second combining network 340 to the radiation unit group 100.

[0111] When the antenna device 1 is in the working state, the signal path where one of the multiple phase adjustment units 210 is located is turned on. For example, it can be set that after the antenna device 1 is powered on, the signal path where the default phase adjustment unit 210 among the multiple phase adjustment units 210 is located is turned on, and the signal paths where the other phase adjustment units 210 are located are disconnected, and after receiving the first control command (or the second control command), the phase adjustment unit 210 with the turned-on signal path is switched from the default phase adjustment unit 210 to the first phase adjustment unit (the second phase adjustment unit). In this way, it can be ensured that after the antenna device 1 is connected to the network, it can use multiple radiation unit groups 100 to communicate with the terminal device 2.

[0112] Figure 5 A schematic structural diagram of an antenna device according to another embodiment of the present application is shown. Figure 5As shown, the antenna device 1 may also include a power divider 400. The power divider 400 is connected to the multiple radiation unit groups 100, and is used to split the communication signal to be transmitted from the transceiver into multiple communication signals, and send the communication signal to the corresponding multiple radiation unit groups 100, and the power divider 400 can also merge the communication signals from the multiple radiation unit groups 100 into a communication signal to be processed, and send the communication signal to be processed to the transceiver unit. At this time, the device device parameters mentioned above may also include: device characteristic parameters of the power divider. In this implementation, there may be no phase difference between the multiple communication signals split by the power divider 400.

[0113] In this implementation, the power distributor 400 may be directly connected to the radiation unit group 100 (eg Figure 5 The connection between the leftmost radiation unit group 100 and the power divider 400); it can also be connected to the control unit 300, and indirectly connected to the radiation unit group 100 through the control unit 300 (such as Figure 5 The connection between the rightmost radiation unit group 100 and the power divider 400). For the radiation unit group 100 directly connected to the power divider 400, the communication signal (i.e., the transmission signal) actually sent out is one of the multiple communication signals obtained after the power divider 400 splits the communication signal to be transmitted. For the radiation unit group 100 indirectly connected to the power divider 400, the communication signal (i.e., the transmission signal) actually sent out is one of the multiple communication signals obtained after the power divider 400 splits the communication signal to be transmitted, and the signal is phase-adjusted by the phase adjustment unit 210 in the phase adjustment unit group 200 whose signal path is turned on. For the radiation unit group 100 directly connected to the power divider 400, the communication signal (i.e., the received signal) actually received is the signal used by the power divider 400 to merge the communication signals to be processed. For the radiation unit group 100 indirectly connected to the power distributor 400, the communication signal actually received (i.e., the received signal) will be phase-adjusted by the phase adjustment unit 210 in the phase adjustment unit group 200 connected to it, and then sent to the power distributor 400 for merging the communication signals to be processed. That is, the communication signal to be processed is actually based on "the communication signal from the radiation unit group 100 directly connected to the power distributor 400" and "the communication signal from the radiation unit group 100 indirectly connected to the power distributor 400 through the phase adjustment unit group 200, which is phase-adjusted by the phase adjustment unit 210 in which the signal path is turned on".

[0114] In one possible implementation, Figure 5As shown, the antenna device 1 may further include a phase shifter 500. The phase shifter 500 is connected to the third radiation unit group among the multiple radiation unit groups 100, and is used to adjust the phase of the communication signal between the third radiation unit group and the terminal device 2. At this time, the device device parameters may also include: device characteristic parameters of the phase shifter. The phase of the communication signal of the third radiation unit group can be adjusted by the phase shifter to improve the adaptability of the device in different application scenarios.

[0115] The third radiation unit group in the plurality of radiation unit groups 100 is any one of the plurality of radiation unit groups, and the phase shifter 500 can be connected to any position between the power divider 400 and the third radiation unit group. For example, if the third radiation unit group is a radiation unit group 100 (such as Figure 5 If the third radiation unit group is the radiation unit group 100 connected to the leftmost radiation unit group 100 in the figure, the phase shifter 500 can be connected between the power divider 400 and the third radiation unit group; if the third radiation unit group is the radiation unit group 100 connected to the phase adjustment unit group 200 (such as Figure 6 If the rightmost radiation unit group 100 is used as the radiation unit group 100 in the figure, the phase shifter 500 can be connected between the third radiation unit group and the phase adjustment unit group 200, or between the control unit 300 and the power divider 400, etc. In this way, the communication signal can be transmitted by the third radiation unit group after phase adjustment by the phase shifter 500, or the communication signal received by the third radiation unit group can be phase adjusted and finally sent to the power divider 400.

[0116] Figure 6 FIG. 1 is a schematic diagram showing a structure of an antenna device according to another embodiment of the present application. In a possible implementation, the antenna device 1 can be grouped as needed, and the antenna device 1 can be divided into one (for example, Figure 2 , Figure 5 Shown is one antenna unit 10) or multiple antenna units 10 (such as Figure 6 Multiple antenna units 10 are shown. Each antenna unit 10 may include multiple radiation unit groups 100, at least one phase adjustment unit group 200, a control unit 300 and a power divider 400.

[0117] Among them, in order to describe the quantitative relationship and phase adjustment situation between multiple radiation unit groups 100, at least one phase adjustment unit group 200, and a control unit 300 in an antenna unit 10, the following is explained in combination with the following implementation examples (the phase difference described in the example only represents the phase difference of the communication signal caused by the phase adjustment unit, and the phase difference caused by other devices such as the phase shifter 500 is not considered in the example).

[0118] Example 1:

[0119] Fig. 7A A schematic diagram of the structure of an antenna device example 1 according to an embodiment of the present application is shown as follows: Fig. 7A As shown, each antenna unit 10 includes two radiation unit groups, namely radiation unit group 101 and radiation unit group 102, a phase adjustment unit group 200, a control unit 300, and a power divider 400. Then, multiple phase adjustment units (not shown in the figure) of the phase adjustment unit group 200 in each antenna unit 10 are connected to any one of the two radiation unit groups 101 and 102 in the antenna unit 10 (such as Fig. 7A The radiation unit group 101 and the control unit 300 shown in the figure are respectively connected, and the control unit 300 and the radiation unit group 102 are respectively connected to the power divider 400.

[0120] The first phase adjustment unit corresponding to the first control command includes: a phase adjustment unit in the phase adjustment unit group 200 of the first antenna unit 10, a phase adjustment unit in the phase adjustment unit group 200 of the second antenna unit 10, and so on.

[0121] In the same antenna unit 10, the first radiation unit group 101 is used to receive the communication signal of the corresponding target subband from the power divider 400 after phase adjustment by the first phase adjustment unit, and the second radiation unit group 102 is used to receive the communication signal of the corresponding target subband from the power divider 400, and both send the received communication signal to the terminal device 2; conversely, the first radiation unit group 101 and the second radiation unit group 102 receive the reception signal of the corresponding target subband from the terminal device 2, and the reception signal of the first radiation unit group 101 will be sent to the power divider 400 after the phase is adjusted by the first phase adjustment unit, and the reception signal of the second radiation unit group 102 will be directly sent to the power divider 400. When the first phase adjustment unit is a dispersion device 212, there is a phase difference between the communication signals of the first radiation unit group 101 and the second radiation unit group 102 caused by the dispersion device 212 (the way in which the phase difference changes refers to the relevant description of the dispersion device 212 above, which is not repeated here), that is, the communication signals of the first radiation unit group 101 and the second radiation unit group 102 have different beam pointing directions in the spatial range. In fact, the first radiation unit group 101 and the second radiation unit group 102 communicate with two different terminal devices 2 in the two beam pointing directions respectively; when the phases between the communication signals of the first radiation unit group 101 and the second radiation unit group 102 are the same, in fact, the first radiation unit group 101 and the second radiation unit group 102 simultaneously communicate with one or more terminal devices 2 in the beam pointing directions.

Then, in each antenna unit 10, the phase adjustment unit group 201 is connected to the radiation unit group 101 and the control unit 301, respectively, the phase adjustment unit group 202 is connected to the radiation unit group 102 and the control unit 302, and the control unit 301 and the control unit 302 are connected to the power divider 400.

Each phase adjustment unit group includes a plurality of phase adjustment units ( Figure 7C not shown).

[0128] The first phase adjustment unit corresponding to the first control command includes: a phase adjustment unit in the phase adjustment unit group 201 of the first antenna unit 10, a phase adjustment unit in the phase adjustment unit group 202 of the first antenna unit 10, a phase adjustment unit in the phase adjustment unit group 201 of the second antenna unit 10, a phase adjustment unit in the phase adjustment unit group 202 of the second antenna unit 10…, and so on.

[0133] In the same antenna unit 10, the radiation unit group 101 is used to receive the communication signal from the power divider 400 corresponding to the target subband after phase adjustment by "a certain phase adjustment unit in the phase adjustment unit group 201", the radiation unit group 102 is used to receive the communication signal from the power divider 400 corresponding to the target subband after phase adjustment by "a certain phase adjustment unit in the phase adjustment unit group 202", and the radiation unit group 103 is used to receive the communication signal from the power divider 400 corresponding to the target subband after phase adjustment by "a certain phase adjustment unit in the phase adjustment unit group 203". All three send the received communication signal to the terminal device 2 through the target subband, and vice versa, receive the received signal from the terminal device 2 corresponding to the target subband (see the relevant description of Example 1 for the process).

[0134] In combination with the above examples 1, 2, 3, and 4, in order to meet the communication signal transmission requirements of the antenna device 1 for different terminal devices 2, in each antenna unit 10, the number of phase adjustment unit groups 200 may be less than or equal to the number of radiation unit groups 100. When the number of multiple radiation unit groups 100 in the antenna unit 10 is greater than 3, the number of phase adjustment unit groups 200 and control units 300 in the antenna unit 10 and the phase adjustment conditions can be set by those skilled in the art with reference to the above description of examples 3 and 4, and this application does not limit this.

While enhancing the receiving / transmitting capabilities of the antenna, it also blocks and shields the interference of other wireless signals from the back (opposite direction) to the received signal.

[0137] Wherein, when the radiation unit group 100 includes a plurality of radiation units, the plurality of radiation units may be arranged in an array. Moreover, all radiation units of the plurality of radiation unit groups 100 may also be arranged in an array. Alternatively, two or more radiation unit groups 100 are divided into an array group, in which the radiation units of the radiation unit group 100 are arranged in an array, and the array arrangement of the radiation units between different array groups may be the same or different. Those skilled in the art may set the radiation array arrangement to form an array as needed, and the present application does not limit this.

[0148] Fig. 9 FIG. 2 shows a schematic diagram of the structure of another base station according to an embodiment of the present application. Fig. 9 As shown, the base station includes the above-mentioned antenna device 1 and a baseband processing unit 4. The baseband processing unit 4 is used to send a first control command to the antenna device 1, and determine the target sub-band corresponding to the communication signal transmitted between the terminal device 2. In this way, the beam pointing corresponding to the communication signal corresponding to the target sub-band transmitted by the antenna device can be adjusted by the first control command, while improving the coverage of the radio electromagnetic wave signal, ensuring that the beam pointing direction of the communication signal can be adjusted in the time domain and frequency domain for different terminal devices. In addition, it is suitable for multi-channel, multi-terminal device, multi-carrier, and multi-standard application scenarios.

[0149] The antenna device 1 is used to communicate with the terminal device 2 under the control of the first control command. The communication process can refer to the relevant description of the antenna device 1 above, which will not be repeated here.

[0150] In this embodiment, the baseband processing unit 4 will determine, based on multiple expected weights of the terminal device 2, the first phase adjustment unit in each phase adjustment unit group 200 that requires signal path conduction in the communication signal transmission of the terminal device 2 when transmitting communication signals with the terminal device 2, and then generate a first control command, and the baseband processing unit 4 will also determine the target subband occupied in the communication signal transmission for the terminal device 2.

[0151] In a possible implementation, the base station may further include a transceiver unit 3 connected to the power distributor 400 in the antenna device 1, and the transceiver unit 3 may be one or more. When there are multiple transceiver units 3, each transceiver unit may be connected to one or more of the multiple power distributors 400. The transceiver unit 3 is used to process the communication signal to be transmitted sent by the baseband processing unit 4 and send it to the power distributor 400, and to process the communication signal to be processed sent by the power distributor 400 and send it to the baseband processing unit 4.

[0152] Among them, after determining the target subband corresponding to the terminal device 2, the baseband processing unit 4 will send the baseband signal that needs to be sent to the terminal device 2 to the transceiver unit 3. The transceiver unit 3 loads the baseband signal onto the target subband and sends it to the power divider 400 as a communication signal to be transmitted. The power divider 400 splits the received communication signal to be transmitted into multiple communication signals and sends them to the corresponding radiation unit group 100 respectively, so that the radiation unit group 100 radiates the received communication signal into the space in the form of electromagnetic waves for reception by the terminal device 2; and, the antenna device 1 can utilize the received signal from the terminal device 2 loaded on the target subband, and send it to the power divider 400, and finally send it to the baseband processing unit 4.

[0153] In a possible implementation, the multiple expected weights can be determined based on the following parameters: device parameters, multiple sub-bands corresponding to the working frequency band of the antenna device, carrier frequency parameters of the reference signal emitted by the radiation unit group, signal parameters determined based on the feedback signal of the terminal device for the reference signal, and terminal device state parameters determined based on the feedback signal. The device parameters include: device characteristic parameters of the radiation unit group, device characteristic parameters of the multiple phase adjustment units, and other parameters. For the meaning of each parameter, please refer to the relevant description of the antenna device 1 above, which will not be repeated here.

[0154] In a possible implementation, the baseband processing unit 4 is further configured to send a second control command to the antenna device 1. The antenna device 1 is configured to transmit a reference signal to the terminal device under the control of the first control command, and receive a feedback signal sent by the terminal device in response to the reference signal.

[0155] Fig.10 A schematic diagram of a process of using expected weights of a BBU in a base station according to an embodiment of the present application is shown. Fig.11 FIG. 4 is a flow chart showing the process of determining and using the expected weight of a BBU in a base station according to an embodiment of the present application. In a possible implementation, the baseband processing unit 4 is also used to perform Fig.11 Steps S11 to S14 calculate multiple expected weights W of the terminal device. ijm , and further based on multiple expected weights W of the terminal device ijm Determine if Fig.10 The first phase adjustment unit and the target subband are shown.

[0156] Step S11, according to one or more of the device parameters, the terminal device state parameters, the carrier frequency parameters corresponding to the reference signal, and the device characteristic parameters of the second phase adjustment unit, determine the terminal device 2 corresponding to the second phase adjustment unit (the second phase adjustment unit includes the phase adjustment unit 210 in each phase adjustment unit group where the signal path is turned on) for each sub-band adjusted by the first weight w′ ija ; where w′ ija Where i represents the terminal device 2 identifier corresponding to the first weight, j represents the subband identifier corresponding to the first weight, a represents that the phase adjustment unit in which the signal path corresponding to the first weight is turned on is the second phase adjustment unit, a∈m.

[0157] Step S12: according to the plurality of first weights w′ ija , the device parameters and the device characteristic parameters of the second phase adjustment unit determine the first weight w′ ija Directional diagram of FXT ija , based on the first weight w′ ija Directional diagram of FXT ija Each first weight w′ can be determined ija The corresponding angle of arrival θ ija The angle of arrival (angle of arrival) can reflect the direction of arrival (DOA) of the communication signal sent by the corresponding first weight, which is also called beam pointing in this article.

[0158] Step S13, according to each first weight w′ ija The angle of arrival θ ija , the device parameters, the terminal equipment state parameters, the device characteristic parameters of the third phase adjustment unit (the third phase adjustment unit includes the phase adjustment unit 210 with the signal path turned on in each phase adjustment unit group 200) in the phase adjustment unit 210 except the second phase adjustment unit, and estimate the multiple second weights w″ of each sub-band of the terminal equipment 2 corresponding to the adjustment of the third phase adjustment unit. ijb Among them, w′ ijb Where i represents the identifier of the terminal device 2 corresponding to the second weight, j represents the subband identifier corresponding to the second weight, b represents the phase adjustment unit of the signal path corresponding to the second weight is the third phase adjustment unit, b∈m, and a∪b=m. In this implementation, the first weight w′ of each terminal device 2 can be used to calculate the phase adjustment unit of the signal path corresponding to the second weight. ija The angle of arrival θ ija, the angle between each terminal device 2 and the normal line of the antenna device 1 is estimated, and then based on the angle between the terminal device 2 and the normal line of the antenna device 1, the device parameters, and the device characteristic parameters of the third phase adjustment unit, the second weight w′ of the terminal device 2 can be estimated. ijb .

[0159] Step S14: The plurality of first weights w′ of the terminal device 2 are ija and the plurality of second weights w″ ijb , determined as multiple expected weights W of the terminal device 2 ijm For example, Fig.10 As shown, when the signal path where the to-be-selected phase adjustment unit 1 is connected, the expected weight corresponding to subband _1 of the terminal device UE_1 is W111, the expected weight corresponding to subband _2 is W121... and the expected weight corresponding to subband _j is W1j1; when the signal path where the to-be-selected phase adjustment unit 2 is connected, the expected weight corresponding to subband _1 of the terminal device UE_1 is W112, the expected weight corresponding to subband _2 is W122... and the expected weight corresponding to subband _j is W1j2; ...; when the signal path where the to-be-selected phase adjustment unit m is connected, the expected weight corresponding to subband _1 of the terminal device UE_1 is W11m, the expected weight corresponding to subband _2 is w12m... and the expected weight corresponding to subband _j is w1jm. That is, the multiple expected weights of the terminal device UE_1 include: W111, W121...W1j1, W112, W122...W1j2,..., W11m, W12m...W1jm.

[0160] The multiple expected weights of the terminal device 2 that can be accurately determined through steps S11 to S14 can meet the communication requirements of the terminal device.

[0161] In a possible implementation, the baseband processing unit 4 is further configured to execute Fig.11 Steps S15 to S17 are shown to be based on the multiple expected weights W of the terminal device 2. ijm The first phase adjustment unit and the target subband are determined. In this way, it is possible to ensure that the communication signal transmission between the antenna device 1 and the terminal device 2 is performed with high transmission efficiency.

[0162] Step S15: based on the multiple expected weights W of the terminal device 2 ijm , determine the transmission rate and R corresponding to the terminal device 2 that meet the rate limit condition when the signal path where the corresponding to-be-selected phase adjustment unit m (the to-be-selected phase adjustment unit includes the phase adjustment unit 210 whose signal path is turned on in each phase adjustment unit group 200) is turned on m , the transmission rate and R mis the transmission rate R corresponding to each terminal device 2 when the signal of the selected phase adjustment unit m is turned on im The sum of the transmission rates of each terminal device 2 is R, where i represents the identifier of the terminal device 2 corresponding to the transmission rate. im is the transmission rate of the terminal device 2 corresponding to at least one sub-band when the signal path where the corresponding to-be-selected phase adjustment unit m is located is turned on. Fig.10 As shown, when there are i terminal devices whose identifiers are 1, 2, ..., i respectively, if the signal path where the phase adjustment unit 1 to be selected is connected, the transmission rate of the terminal device 2 that meets the rate limit condition and R1 are calculated based on R 11 , R 21 …R i1 If the signal path where the selected phase adjustment unit 2 is located is turned on, the transmission rate of the terminal device 2 that meets the rate limit condition and R2 are determined according to R 12 , R 22 …R i2 The determined rate and ... If the signal path where the selected phase adjustment unit m is located is connected, the transmission rate of the terminal device 2 that meets the rate limit condition and R m According to R 1m , R 2m …R im The determined rate and.

[0163] In a possible implementation, the rate limit bar may include: the transmission rate R of the terminal device i im Less than or equal to the highest transmission rate corresponding to terminal device i and the transmission rate R of terminal device i im is greater than or equal to the minimum transmission rate corresponding to the terminal device i; and when the signal path where the corresponding candidate phase adjustment unit m is located is turned on, the transmission rates of all terminal devices and R m The maximum transmission rate can be set according to the total transmission rate of all communication signals that can be transmitted by the communication system, the number of terminal devices 2, etc., and the minimum transmission rate can be set according to the antenna device 1 and the corresponding terminal device 2 meeting the minimum standard for communication signal transmission to ensure that the corresponding terminal device 2 can communicate normally with the antenna device 1. Those skilled in the art can set the rate limit conditions according to actual needs, and this application does not limit this.

[0164] Step S16, the maximum value of the sum of transmission rates corresponding to the conduction of the signal paths where all the candidate phase adjustment units are located is determined as the target transmission rate sum, and the candidate phase adjustment unit corresponding to the target transmission rate sum is determined as the first phase adjustment unit. Fig.10As shown, there are i terminal devices whose identifiers are 1, 2, ..., i, respectively. The transmission rate and R1 corresponding to the signal path where the selected phase adjustment unit 1 is located, the transmission rate and R2 corresponding to the signal path where the selected phase adjustment unit 2 is located, ..., the transmission rate and R2 corresponding to the signal path where the selected phase adjustment unit m is located m In the example, since the transmission rate and R1 corresponding to the signal path conduction where the candidate phase adjustment unit 1 is located has the largest value, the transmission rate and R1 are determined as the target transmission rate and, then the candidate phase adjustment unit 1 corresponding to the transmission rate and R1 is the first phase adjustment unit.

[0165] Step S17, determining the sub-band corresponding to the transmission rate of the terminal device 2 that constitutes the target transmission rate and as the target sub-band corresponding to the terminal device 2. Fig.10 As shown, since the target transmission rate and R1 are based on R 11 , R 21 …R i1 If determined, the target subband corresponding to UE_1 is subband_5 and subband_6, the target subband corresponding to UE_2 is subband_8 and subband_9... and the target subband corresponding to UE_i is subband_3 and subband_4.

[0166] To further describe the antenna device 1 and the base station shown in the present application in the process of implementing the resource allocation of the terminal device, compared with the difference of the related art, the following example is used to illustrate that it is assumed that there are 10 terminal devices 2 distributed in the network where the base station is located, namely U0, U1, U2...U9. The antenna device 1 includes multiple antenna units 10, and each antenna unit 10 includes only two radiation unit groups 100 and a phase adjustment unit group 200. The phase adjustment unit group 200 includes a dispersion device 212 (the phase difference generated is calculated according to Figure 4 G3 changes) and a non-dispersive device 211 (the phase difference generated is as follows Figure 4 G1 in the figure shows a fixed value of 180°). Where:

[0167] When the signal path where the dispersion device 212 in the antenna device 1 is located is turned on, refer to Figure 4 From the G2 line, we can see that the beam pointing of the transmitted communication signal can change slowly with the frequency, and the beam pointing does not change much. The bandwidth occupied by the change is 0.4X of the total bandwidth of the working frequency band (that is, 0.4 times the total bandwidth of the working frequency band). Fig. 12A , Fig. 12B A schematic diagram of terminal device resource allocation according to an embodiment of the present application is shown. Fig. 12A , Fig. 12BThe horizontal axis represents the frequency f of the subband occupied by the transmitted signal, and the vertical axis represents the beam pointing Doa of the transmitted signal (which corresponds to the phase of the transmitted signal). In the case of 10 terminal devices, 2 unit time units are required to complete the coverage of all terminal devices. The unit time unit can be the time length required for the antenna device 1 to transmit a transmitted signal. The unit time unit can be represented by TTI (transmission time interval), and the time length occupied by a TTI can be a unit time unit. Fig. 12A In the first unit time unit shown in the figure, the antenna device 1 transmits four narrow beams with different beam directions Doa (corresponding to the phase of the transmitted signal) to cover the terminal devices in the corresponding partial spatial areas respectively, and two terminal devices are covered by the same beam. The two terminal devices covered by the same beam share 0.4X the total bandwidth of the working frequency band (that is, occupying 4 / 10 of the total bandwidth of the working frequency band). That is, in the first unit time unit, U1 and U6 are covered by the transmitted signal of the first beam pointing to Doa, and the bandwidth of the target sub-band occupied by the two (that is, Fig. 12A The width of the sub-band occupied by U1 and U6 (the width of the horizontal axis frequency f) is 0.4X the total bandwidth of the working frequency band; U4 and U9 are covered by the transmission signal of the second beam pointing to Doa, and the bandwidth of the sub-band occupied by the two (that is, Fig. 12A The width of the horizontal axis frequency f occupied by U4 and U9 is 0.4X the total bandwidth of the working frequency band; U2 and U7 are covered by the transmission signal of the third beam pointing to Doa, and the bandwidth of the sub-band occupied by the two (that is, Fig. 12A The width of U2 and U7 (the width of the horizontal axis frequency f) is 0.4X the total bandwidth of the working frequency band; U5 and U0 are covered by the transmission signal of the fourth beam pointing to Doa, and the bandwidth of the sub-band occupied by the two (that is, Fig. 12A The width of U0 and U5 (the width of the horizontal axis frequency f) is 0.4X the total bandwidth of the working frequency band. Fig. 12B In the second unit time unit shown in the figure, U3 and U8 are covered by the transmission signal of the fifth beam pointing to Doa, and the bandwidth of the target subband occupied by the two (i.e. Fig. 12BThe width of the horizontal axis frequency f occupied by U1 and U6 is 0.4*2X the total bandwidth of the working frequency band. It can be seen that within two unit time units, at least one of the time domain (corresponding unit time unit), spatial domain (beam pointing), and frequency domain (occupied subband) resources of the communication signals received by U0, U1, U2...U9 is different, and the settings can be made for terminal devices while ensuring coverage. After averaging each unit time unit, the resource allocation of each terminal device is as follows: each terminal device uses 0.4 / 2X*0.8+0.4X*0.2 of the total working frequency band bandwidth (8 terminal devices transmit signals in the first unit time unit, accounting for 0.8 of the total 10 terminal devices, so the frequency band occupancy calculation for each terminal device needs to be multiplied by 0.8, that is, 0.4 / 2X*0.8; similarly, 2 terminal devices transmit signals in the second unit time unit, accounting for 0.2 of the total 10 terminal devices, so the frequency band occupancy calculation for each terminal device needs to be multiplied by 0.2, that is, 0.4X*0.2), each terminal device uses 0.5X unit time unit (since two unit time units are required to complete the transmission of the transmission signals of 10 terminal devices, the duration used by each terminal device is the duration corresponding to 0.5 times the unit time unit), the antenna gain of each terminal device is 5X the traditional beam (that is, 5 times the traditional beam), and the two terminal devices reuse the same time-frequency resources.

[0168] When the signal path where the non-dispersive device 211 in the antenna device 1 is located is turned on, Figure 4 From the G1 line, we can see that the beam pointing direction of the transmitted communication signal does not change with frequency. Fig. 12C , Fig.12D , Fig.12E A schematic diagram of terminal device resource allocation according to an embodiment of the present application is shown. Figure 12C-12E The horizontal axis represents the frequency f of the subband occupied by the transmitted signal, and the vertical axis represents the beam pointing Doa of the transmitted signal (which corresponds to the phase of the transmitted signal). In the case of 10 terminal devices, 3 unit time units are required to complete the coverage of all terminal devices. In each unit time unit, the antenna device 1 transmits 2 narrow beams with different beam pointing directions to cover the terminal devices in the corresponding partial spatial area respectively. Two terminal devices are covered by the same beam, and the two terminal devices covered by the same beam share 1X the total bandwidth of the working frequency band (that is, occupying the entire total bandwidth of the working frequency band). That is, in the case of Fig. 12C In the first unit time unit shown in the figure, U1 and U6 are covered by the transmission signal of the first beam pointing to Doa, and the bandwidth of the target subband occupied by the two (i.e. Fig. 12CThe width of U1 and U6 on the horizontal axis frequency f) is 1X the total bandwidth of the working frequency band; U4 and U9 are covered by the transmission signal of the second beam pointing to Doa, and the bandwidth of the sub-band occupied by the two (that is, Fig. 12C The width of U4 and U9 (the width of the horizontal axis frequency f) is 1X the total bandwidth of the working frequency band. Fig.12D In the second unit time unit shown in the figure, U2 and U7 are covered by the transmission signal of the third beam pointing to Doa, and the bandwidth of the sub-band occupied by the two (i.e. Fig.12D The width of U2 and U7 on the horizontal axis frequency f) is 1X the total bandwidth of the working frequency band; U5 and U0 are covered by the transmission signal of the fourth beam pointing to Doa, and the bandwidth of the sub-band occupied by the two (that is, Fig.12D The width of U0 and U5 on the horizontal axis frequency f) is 1X the total bandwidth of the working frequency band. Fig.12E In the third unit time unit shown in the figure, U3 and U8 are covered by the transmission signal of the fifth beam pointing to Doa, and the bandwidth of the target subband occupied by the two (i.e. Fig.12E In the figure, U1 and U6 occupy the width of the horizontal axis frequency f) of the total bandwidth of the working frequency band of 1X. It can be seen that within the three unit time units, at least one of the time domain (corresponding unit time unit), spatial domain (beam pointing), and frequency domain (occupied subband) resources of the communication signals received by U0, U1...U9 is different, and can be set for terminal devices while ensuring coverage. That is, after averaging each unit time unit, in the communication with 10 terminal devices, each terminal device uses 0.5X the total bandwidth of the working frequency band, and each terminal device uses 0.33X unit time unit (since three unit time units are required to complete the transmission of the transmission signals of 10 terminal devices, the duration used by each terminal device is the duration corresponding to 0.33 times the unit time unit), the antenna gain of each terminal device is 5X the traditional beam, and the two terminal devices reuse the same time-frequency resources.

[0169] The related technology has the following implementation methods:

[0170] Fig.13A The figure shows the antenna connection diagram in the base station based on the 4-transmit 4-receive 4T4R analog beamforming ABF (analog beamforming, referred to as ABF) system. Fig. 13B FIG. 4 shows a schematic diagram of terminal equipment resource allocation based on a base station of a 4T4RABF system. Fig.13A As shown in FIG. 1 , in the 4T4RABF system, four transceiver units TRX are connected to the positive and negative polarized antenna ports of two radiation unit groups respectively. Fig. 13B As shown, Fig. 13BThe horizontal axis represents the frequency f of the subband occupied by the transmitted signal, and the vertical axis represents the beam pointing Doa of the transmitted signal (which corresponds to the phase of the transmitted signal). In the case of 10 terminal devices (such as U0, U1, U2...U9), one unit time unit completes the coverage of all terminal devices. Among them, each terminal device uses 0.1X the total bandwidth of the working frequency band, each terminal device uses 1X unit time unit, and each terminal device antenna gain is 1X traditional beam, and the terminal devices do not reuse the same time-frequency resources. However, the coverage of this implementation is weak and the capacity is low.

[0171] Fig.14A The figure shows the antenna connection diagram in the base station based on the MM digital beamforming DBF (digital beamforming, DBF for short), Fig. 14B FIG. 4 shows a schematic diagram of terminal equipment resource allocation based on a base station of an MM DBF system. Fig.14A As shown, in the MM DBF system, a plurality of transceiver units TRX1, TRX2 ... TRXn and a plurality of radiation unit groups are provided, and each TRX is connected to a positive polarization or negative polarization antenna port of a radiation unit group. Fig. 14B As shown, Fig. 14B The horizontal axis represents the frequency f of the subband occupied by the transmitted signal, and the vertical axis represents the beam pointing Doa of the transmitted signal (which corresponds to the phase of the transmitted signal). In the case of 10 terminal devices (such as U0, U1, U2...U9), one unit time unit completes the coverage of all terminal devices. That is, in the communication with 10 terminal devices, each terminal device uses 0.5X the total bandwidth of the working frequency band, each terminal device uses 1X unit time unit, each terminal device antenna gain is 5X traditional beam, and 5 terminal devices reuse the same time-frequency resources. However, this implementation method has a large number of channels, high cost, and complex base station settings.

Fig.15A As shown, in the MM HBF system, a TRX and a plurality of radiation unit groups are provided, the TRX is connected to the antenna port of each radiation unit group, and a phase shifter is provided between at least one radiation unit group and the TRX. Fig. 15B , Fig. 15C , Fig.15D As shown, Figure 15B-Figure 15DThe horizontal axis represents the frequency f of the subband occupied by the transmitted signal, and the vertical axis represents the beam pointing Doa of the transmitted signal (which corresponds to the phase of the transmitted signal). Assuming that there are two beams in each unit time unit, when there are 10 terminal devices (such as U0, U1, U2...U9), 3 TTIs complete the coverage of all terminal devices. That is, in the communication with 10 terminal devices, each terminal device uses 0.5X the total bandwidth of the working frequency band, each terminal device uses 0.33X the unit time unit, the antenna gain of each terminal device is 5X the traditional beam, and 2 terminal devices reuse the same time-frequency resources. However, this implementation method cannot achieve simultaneous concurrency of communication information for application scenarios with different spatial angles, multiple terminal devices, multiple carriers, and multiple standards.
