Description

Technical Field

[0001] This application relates to the field of wireless communication, and more particularly to a multi-plane antenna system and a power allocation method.

Background Art

[0002] In a wireless communication network, a base station that functions as a key network node plays an important role in the communication network. With the development of mobile communication, the form of base station devices has also become diversified. For example, a multi-plane antenna system architecture is formed by two radiation surfaces (two planes), three radiation surfaces (three planes), or multiple radiation surfaces (multi-planes). However, in a multi-plane antenna system architecture, each radiation surface independently takes charge of the coverage of the corresponding cell (or sector), that is, the transmission power is configured independently for each radiation surface. In this way, for the entire multi-plane antenna system architecture, when some radiation surfaces do not transmit power, the maximum transmission power of the multi-plane antenna system is the maximum transmission power of the radiation surfaces that can currently transmit power. In this case, if the available transmission power value of the multi-plane antenna system is higher than the maximum transmission power of the current multi-plane antenna system, the maximum utilization of the transmission power of the entire multi-plane antenna system cannot be implemented.

Summary of the Invention

[0003] Embodiments of this application provide a multi-plane antenna system and a power allocation method. A power control module is used to configure the transmission power of the entire multi-plane antenna system and to perform adjustment, sharing, and allocation of power among multiple antennas, as well as to implement the maximum power utilization of the antenna system.

Means for Solving the Problems

[0004] According to a first embodiment, a polyplane antenna system is provided, comprising at least two radiating surfaces configured to emit signals, each radiating surface including at least one antenna, each radiating surface connected to at least one radio frequency channel, and the orientation of the M radiating surfaces of the at least two radiating surfaces being different, where M is a positive integer of 2 or more, and a power control module configured to determine the transmit power of the at least two radiating surfaces based on the available transmit power values ​​of the polyplane antenna system, the power control module being logically connected to the radio frequency channels corresponding to the at least two radiating surfaces.

[0005] It should be understood that the condition that at least two of the M radiating surfaces have different orientations can be understood as the case where the orientations of at least two radiating surfaces included in a polyhedral antenna system are not exactly the same. Alternatively, the orientations of at least two radiating surfaces in a polyhedral antenna system are different. In other words, in at least two radiating surfaces included in a polyhedral antenna system, the orientations of the two radiating surfaces must be different.

[0006] It should be understood that two radiating planes with different orientations serve two different cells. Alternatively, the two radiating planes have different orientations, and the cells they serve are also different.

[0007] For example, a multifaceted antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2). The orientation of radiating surface #1 and radiating surface #2 are different.

[0008] For example, a multifaceted antenna system includes three radiating surfaces (radiating surface #1, radiating surface #2, and radiating surface #3). The orientation of radiating surface #1 and radiating surface #2 are the same, while the orientation of radiating surface #3 is different from the orientations of radiating surface #1 and radiating surface #2.

[0009] For example, a multifaceted antenna system includes three radiating surfaces (radiating surface #1, radiating surface #2, and radiating surface #3). The orientations of radiating surface #1, radiating surface #2, and radiating surface #3 are all different.

[0010] It should be understood that the logical connection of the power control module to radio frequency channels corresponding to at least two radiating surfaces can be understood as the case in a multifaceted antenna system where radio frequency channels corresponding to at least two radiating surfaces are logically connected to the power control module. Alternatively, the power control module may be separately connected to at least two radio frequency channels corresponding to different radiating surfaces. It should be understood that the logical connection of the power control module to radio frequency channels corresponding to at least two radiating surfaces can mean that the power control module is directly or indirectly connected to radio frequency channels corresponding to at least two radiating surfaces. The method of connection between the power control module and radio frequency channels corresponding to at least two radiating surfaces is not limited in this application.

[0011] It should be understood that the transmit power of a multifaceted antenna system is the power of the signal (electrical signal) input to the multifaceted antenna system at a given time and effectively converted into electromagnetic waves. The maximum transmit power (rated transmit power) of a multifaceted antenna system is the maximum value that can be achieved by the transmit power of the multifaceted antenna system, or the maximum value that can be achieved by the sum of the transmit powers of all radiating surfaces included in the multifaceted antenna system at the same time. The available transmit power value of a multifaceted antenna system is obtained by subtracting the transmit power used (e.g., the transmit power used for a particular requirement) from the maximum transmit power of the multifaceted antenna system.

[0012] It should be understood that the available transmit power value of a multifaceted antenna system is less than or equal to the maximum transmit power of the multifaceted antenna system. Generally, the maximum transmit power of a multifaceted antenna system is equal to the available transmit power value of the multifaceted antenna system. In the aforementioned solution, a power control module is used to configure the power of the entire multifaceted antenna system and to perform coordination between multiple radiating surfaces as well as power sharing and allocation. Furthermore, when at least two radiating surfaces in a multifaceted antenna system are oriented differently and users in different areas (or cells) are served, power sharing between different cells may be implemented.

[0013] In one possible implementation, the power control module is configured to determine the transmit power of at least two radiating surfaces based on the available transmit power values ​​of the multifaceted antenna system, which includes the power control module being configured to determine the power amplification output of power amplification modules corresponding to at least two radiating surfaces based on the available transmit power values ​​of the multifaceted antenna system and the service requirements corresponding to at least two radiating surfaces.

[0014] For example, a multifaceted antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2). The available transmit power value for the multifaceted antenna system is 300W, and the maximum transmit power of both radiating surface #1 and radiating surface #2 is 200W. If the transmit power of the service requirement corresponding to radiating surface #1 is 100W and the transmit power of the service requirement corresponding to radiating surface #2 is 100W, the power control module will determine, based on the service requirements corresponding to radiating surface #1 and radiating surface #2, that the power amplification output of the power amplification module corresponding to radiating surface #1 is 100W and the power amplification output of the power amplification module corresponding to radiating surface #2 is 100W.

[0015] In one possible implementation, the power control module is configured to determine a power difference based on the available transmit power value of the polyplane antenna system and the service requirements corresponding to at least two radiating surfaces, the power difference being the difference between the sum of the service requirements corresponding to at least two radiating surfaces and the available transmit power value of the polyplane antenna system, and the power control module is configured to determine the power amplification output of the power amplification module corresponding to at least two radiating surfaces based on the service requirements corresponding to at least two radiating surfaces and the power difference.

[0016] For example, a multifaceted antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2). The available transmit power value of the multifaceted antenna system is 300W, and the maximum transmit power of both radiating surface #1 and radiating surface #2 is 200W. If the transmit power of the service requirement corresponding to radiating surface #1 is 100W and the transmit power of the service requirement corresponding to radiating surface #2 is 200W, then the sum of the transmit power of the service requirement corresponding to radiating surface #1 and the transmit power of the service requirement corresponding to radiating surface #2 is 300W. In this case, the power difference is 0. Therefore, the power control module determines that the power amplification output of the power amplification module corresponding to radiating surface #1 is 100W and the power amplification output of the power amplification module corresponding to radiating surface #2 is 200W.

[0017] For example, a multifaceted antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2). The available transmit power value of the multifaceted antenna system is 300W, and the maximum transmit power of both radiating surface #1 and radiating surface #2 is 200W. If the transmit power of the service requirement corresponding to radiating surface #1 is 100W and the transmit power of the service requirement corresponding to radiating surface #2 is 150W, then the sum of the transmit power of the service requirement corresponding to radiating surface #1 and the transmit power of the service requirement corresponding to radiating surface #2 is 250W. In this case, the power difference is 50W (or, in this case, in addition to meeting the transmit power of the service requirement corresponding to radiating surface #1 and the transmit power of the service requirement corresponding to radiating surface #2, the available transmit power value of the multifaceted antenna system still has 50W remaining). Therefore, the power control module may further allocate the unallocated (remaining) 50W to radiating surface #1 and radiating surface #2.

[0018] It should be understood that when the power control module further allocates unallocated transmit power to radiating surfaces #1 and #2, the allocation may be performed based on ratio, service requirements, or radiating priority. This is not limited to the present application.

[0019] For example, the power control module allocates the unallocated 50W to radiator #1 and radiator #2 based on a ratio. For example, the power control module further allocates 25W to radiator #1 and radiator #2 based on a 1:1 (average) ratio. In other words, in this case, the power amplification output of the power amplification module corresponding to radiator #1 includes the sum of the service requirement transmit power for radiator #1 (100W) and the additionally allocated 25W, i.e., 125W, and the power amplification output of the power amplification module corresponding to radiator #2 includes the sum of the service requirement transmit power for radiator #2 (150W) and the additionally allocated 25W, i.e., 175W. Alternatively, the power control module further allocates 40W to radiator #1 and 10W to radiator #2 based on a 4:1 ratio. In other words, in this case, the power amplification output of the power amplification module corresponding to radiating surface #1 includes the total of the service requirement transmit power for radiating surface #1 (100W) plus an additional 40W, i.e., 140W, and the power amplification output of the power amplification module corresponding to radiating surface #2 includes the total of the service requirement transmit power for radiating surface #2 (150W) plus an additional 10W, i.e., 160W.

[0020] In another example, the power control module allocates the unallocated 50W to radiator #1 and radiator #2 based on service requirements. If the transmit power of the service requirement corresponding to radiator #1 is higher than the transmit power of the service requirement corresponding to radiator #2, an additional 30W is allocated to radiator #1 and an additional 20W to radiator #2. In other words, in this case, the power amplification output of the power amplification module corresponding to radiator #1 includes the sum of the transmit power of the service requirement corresponding to radiator #1 (100W) and the additionally allocated 30W, i.e., 130W, and the power amplification output of the power amplification module corresponding to radiator #2 includes the sum of the transmit power of the service requirement corresponding to radiator #2 (150W) and the additionally allocated 20W, i.e., 170W.

[0021] The aforementioned solution uses a power control module to adjust the power amplification output of the power amplification module within the multifaceted antenna system based on specific service requirements, thereby enabling power sharing and allocation among the multiple radiating surfaces within the multifaceted antenna system.

[0022] When the power control module further allocates unallocated transmit power to at least two radiating surfaces, it is necessary to improve the power amplification capability of the power amplification module in the radio frequency channels corresponding to the radiating surfaces in order to avoid the problem that the actually allocated transmit power exceeds the maximum transmit power of the radiating surfaces. Consequently, it should be understood that when the power control module shares and allocates the available transmit power values ​​of the multifaceted antenna system between different radiating surfaces, the power amplification capability of the power amplification module does not constitute a limitation.

[0023] In one possible implementation, each radio frequency channel includes a power amplification module, and the power amplification capability of at least one power amplification module in the polyplane antenna system is greater than the value obtained by dividing the maximum transmit power of the polyplane antenna system by the number of radio frequency channels in the polyplane antenna system. It should be understood that each radio frequency channel includes a power amplification module if, on at least two radiating surfaces included in the polyplane antenna system, at least one radio frequency channel corresponding to each radiating surface includes (corresponds to) one power amplification module (power amplifier, PA) to amplify the radio frequency signal and increase the output power.

[0024] In a multi-faceted antenna system, it should be understood that the power amplification capability of at least one power amplification module is greater than the value obtained by dividing the maximum transmit power of the multi-faceted antenna system by the total number of radio frequency channels included in the multi-faceted antenna system.

[0025] For example, a polyface antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2). Radiating surface #1 and radiating surface #2 are connected to radio frequency channel #1 and radio frequency channel #2, respectively. Radio frequency channel #1 and radio frequency channel #2 include (correspond to) power amplification modules #1 and power amplification modules #2, respectively. The maximum transmit power of the polyface antenna system is 200W, and the power amplification capability of power amplification module #1 is greater than the value obtained by dividing the maximum transmit power of the polyface antenna system (200W) by the number of radio frequency channels included in the polyface antenna system (2), i.e., the power amplification capability of power amplification module #1 is greater than 100W. In another example, the power amplification capability of power amplification module #2 is greater than 100W. In yet another example, both the power amplification capability of power amplification module #1 and the power amplification capability of power amplification module #2 are greater than 100W.

[0026] For example, a polyface antenna system includes three radiating surfaces (radiating surface #1, radiating surface #2, and radiating surface #3). Radiating surfaces #1, #2, and #3 are connected to radio frequency channels #1, #2, and #3, respectively. Radio frequency channels #1, #2, and #3 include (correspond to) power amplification modules #1, #2, and #3, respectively. The maximum transmit power of the polyface antenna system is 600W, and the power amplification capability of power amplification module #1 is greater than the value obtained by dividing the maximum transmit power of the polyface antenna system (600W) by the number of radio frequency channels included in the polyface antenna system (3), i.e., the power amplification capability of power amplification module #1 is greater than 200W. In another example, the power amplification capability of both power amplification module #1 and power amplification module #2 is greater than 200W. In another example, the power amplification capacity of power amplification module #1, power amplification capacity of power amplification module #2, and power amplification capacity of power amplification module #3 are all greater than 200W.

[0027] Note that the number of radio frequency channels connected to each radiation surface is not limited in this application.

[0028] In a multi - face antenna system, when at least two radio frequency channels are connected to a radiation surface, it should be understood that the power amplification capacity of the power amplification module included in one of the radio frequency channels needs to be greater than the value obtained by dividing the maximum transmission power of the multi - face antenna system by the total number of radio frequency channels included in the multi - face antenna system. The power amplification capacity of the power amplification module included in another radio frequency channel of the radiation surface is not limited. For example, the power amplification capacity of the power amplification module included in another radio frequency channel of the radiation surface may be smaller than the value obtained by dividing the maximum transmission power of the multi - face antenna system by the total number of radio frequency channels included in the multi - face antenna system.

[0029] For example, a multi - face antenna system includes two radiation surfaces (radiation surface #1 and radiation surface #2). Radiation surface #1 is connected to radio frequency channel #1 and radio frequency channel #2, and radiation surface #2 is connected to radio frequency channel #3. Radio frequency channel #1, radio frequency channel #2, and radio frequency channel #3 each include (correspond to) power amplification module #1, power amplification module #2, and power amplification module #3 respectively. The maximum transmission power of the multi - face antenna system is 300W. Regarding radiation surface #1, the power amplification capacity of power amplification module #1 is greater than the value obtained by dividing the maximum transmission power of the multi - face antenna system (300W) by the number of radio frequency channels (3) included in the multi - face antenna system. That is, the power amplification capacity of power amplification module #1 is greater than 100W, and the power amplification capacity of power amplification module #2 may be less than 100W. In another example, both the power amplification capacity of power amplification module #1 and the power amplification capacity of power amplification module #3 are greater than 100W.

[0030] The above solution improves the power amplification capability of the power amplification module included in the radio frequency channel. As a result, the power that can support the multifaceted antenna system is flexibly shared and allocated between different radiating surfaces without being limited by the power amplification capability, thereby improving the performance of the multifaceted antenna system.

[0031] In one possible implementation, at least two radiating surfaces include a first radiating surface and a second radiating surface, the first radiating surface having a maximum transmit power at a first time point, the maximum transmit power of the first radiating surface being a first power value, the second radiating surface having a maximum transmit power at a second time point, the maximum transmit power of the second radiating surface being a second power value, the sum of the first and second power values ​​being greater than the maximum transmit power of the multifaceted antenna system, the first power value being less than or equal to the maximum transmit power of the multifaceted antenna system, and the second power value being less than or equal to the maximum transmit power of the multifaceted antenna system.

[0032] In the aforementioned solution, a power control module is used so that the sum of the maximum transmit power of the first radiating surface and the maximum transmit power of the second radiating surface at different points in time is greater than the maximum transmit power of the multifaceted antenna system. This avoids the low power utilization problem that occurs when the maximum transmit power of the radiating surfaces at different points in time cannot exceed the maximum transmit power of the antenna system. Power sharing and allocation occur among the multiple radiating surfaces within the multifaceted antenna system, making it possible to maximize the transmit power of the multifaceted antenna system and improving system performance.

[0033] In one possible implementation, at least two radiating surfaces include a first radiating surface and a second radiating surface, the transmit power of the first radiating surface at a third time point is a third power value, the transmit power of the second radiating surface at a third time point is a fourth power value, and the power control module is further configured to share and allocate the transmit power of the first radiating surface and the transmit power of the second radiating surface such that the sum of the third power value and the fourth power value is less than or equal to the maximum transmit power of the polyhedron antenna system.

[0034] In the aforementioned solution, a power control module is used to ensure the proper operation of the multifaceted antenna system by ensuring that the sum of the transmit power of the first radiating surface and the transmit power of the second radiating surface at the same time does not exceed the maximum transmit power of the multifaceted antenna system.

[0035] In one possible implementation, on each radiating surface, at least one antenna and radio frequency channel are located inside an active antenna unit; or at least one antenna is located inside a passive antenna and the radio frequency channel is located inside a remote radio unit.

[0036] In the aforementioned solution, to increase the diversity of the physical implementation of the polyface antenna system, the antennas included in each radiating surface of the polyface antenna system and the radio frequency channels connected to those radiating surfaces may be located within the same active antenna unit, or they may be located separately within the passive antenna and remote radio unit.

[0037] In one possible implementation, the power control module is located inside the active antenna unit or the remote radio unit; or, the power control module is located outside the active antenna unit or the remote radio unit.

[0038] In the aforementioned solution, the power control module included in the multifaceted antenna system may be located inside or outside the active antenna unit or the remote radio unit to increase the versatility of the physical implementation of the multifaceted antenna system.

[0039] According to a second aspect, a power allocation method is provided which is applied to a polyhedron antenna system, the polyhedron antenna system comprising at least two radiating surfaces and a power control module.

[0040] The method may include the steps of: a power control module determining the transmit power of at least two radiating surfaces based on the available transmit power values ​​of a multifaceted antenna system; and the power control module allocating the transmit power of at least two radiating surfaces to at least two radiating surfaces, each of the at least two radiating surfaces including at least one antenna, each radiating surface connected to at least one radio frequency channel, the orientation of the M radiating surfaces of the at least two radiating surfaces being different, M being a positive integer greater than or equal to 2, and the power control module being logically connected to the radio frequency channels corresponding to the at least two radiating surfaces.

[0041] In one possible implementation, the power control module is configured to determine the transmit power of at least two radiating surfaces based on the available transmit power values ​​of the multifaceted antenna system, which includes the power control module being configured to determine the power amplification output of power amplification modules corresponding to at least two radiating surfaces based on the available transmit power values ​​of the multifaceted antenna system and the service requirements corresponding to at least two radiating surfaces.

[0042] In one possible implementation, the power control module is configured to determine the power amplification output of power amplification modules corresponding to at least two radiating surfaces based on the available transmit power values ​​of the polyplane antenna system and the service requirements corresponding to at least two radiating surfaces, which includes the power control module being configured to determine a power difference based on the available transmit power values ​​of the polyplane antenna system and the service requirements corresponding to at least two radiating surfaces, wherein the power difference is the difference between the sum of the service requirements corresponding to at least two radiating surfaces and the available transmit power values ​​of the polyplane antenna system, and the power control module being configured to determine the power amplification output of power amplification modules corresponding to at least two radiating surfaces based on the service requirements corresponding to at least two radiating surfaces and the power difference.

[0043] In one possible implementation, each radio frequency channel includes a power amplification module, and the power amplification capability of at least one power amplification module in the multifaceted antenna system is greater than the value obtained by dividing the maximum transmit power of the multifaceted antenna system by the number of radio frequency channels in the multifaceted antenna system.

[0044] In one possible implementation, at least two radiating surfaces include a first radiating surface and a second radiating surface, the first radiating surface having a maximum transmit power at a first time point, the maximum transmit power of the first radiating surface being a first power value, the second radiating surface having a maximum transmit power at a second time point, the maximum transmit power of the second radiating surface being a second power value, the sum of the first and second power values ​​being greater than the maximum transmit power of the multifaceted antenna system, the first power value being less than or equal to the maximum transmit power of the multifaceted antenna system, and the second power value being less than or equal to the maximum transmit power of the multifaceted antenna system.

[0045] In one possible implementation, at least two radiating surfaces include a first radiating surface and a second radiating surface, the transmit power of the first radiating surface at a third time point is the third power value, the transmit power of the second radiating surface at a third time point is the fourth power value, and the sum of the third and fourth power values ​​is less than or equal to the maximum transmit power of the multifaceted antenna system.

[0046] For a description of the relevant content and beneficial effects of the power allocation method provided in the second embodiment, please refer to the multifaceted antenna system shown in the first embodiment. Details will not be repeated here.

[0047] According to a third aspect, a device is provided that can perform a communication device including the multifaceted antenna system described above according to the first aspect, or a method according to any one of the possible implementation forms of the second aspect.

[0049] [Figure 1] A diagram of a passive antenna. [Figure 2] This is a diagram of a two-sided antenna system. [Figure 3] This is a diagram of a three-sided antenna system. [Figure 4] This is a diagram of another three-sided antenna system. [Figure 5] This is a diagram illustrating the structure of a two-sided antenna system. [Figure 6] This is a diagram illustrating the structure of a three-sided antenna system. [Modes for carrying out the invention]

[0050] The following explains terms that may appear in the embodiments of this application.

[0051] 1. Active antenna An active antenna includes at least an amplifier (e.g., a power amplifier (PA)), a filter, and a radiating antenna section. The active antenna integrates the radio frequency portion of a base station into the antenna, and the coordination between the multi-channel radio frequency and the antenna elements is used to perform spatial beamforming and complete the reception and transmission of radio frequency signals.

[0052] 2. Passive antenna A passive antenna is a radiating element formed entirely of passive components. Generally, a passive antenna system includes at least a passive radiator (antenna element), passive impedance matching, a passive balun, and a passive interconnect (generally with an impedance of 50 ohms or 75 ohms). Generally, passive antennas are mounted on poles. As shown in Figure 1, the pole is on the back side, and the passive antenna is on the front side, transmitting signals by electromagnetic radiation.

[0053] In this specification, claims, and accompanying drawings, terms such as “first,” “second,” “third,” and “fourth” (if any) are intended to distinguish between similar subjects and do not necessarily indicate a specific order or sequence. Data referred to in this manner are interchangeable in appropriate contexts, and it should be understood that the embodiments described herein may be implemented in any order other than those illustrated or described herein. In addition, “include,” “have,” and any other variations are intended to include non-exclusive inclusions. For example, a process, method, system, product, or device including a list of steps or units is not necessarily limited to these explicitly listed steps or units and may include other steps or units that are not explicitly listed or are specific to such process, method, product, or device.

[0054] The technical solutions in the embodiments of this application will be described below with reference to the attached drawings.

[0055] Figures 2 and 3 show diagrams of a two-sided antenna system 200 and a three-sided antenna system 300, respectively. In Figure 2, the two-sided antenna system 200 is formed by radiating surfaces 210 and 220. In the two-sided antenna system 200, antenna radiating surfaces are located on both sides of the system architecture to transmit electromagnetic signals. In Figure 3, the three-sided antenna system 300 (three cells and one base station) is formed by radiating surfaces 310, 320, and 330. In the three-sided antenna system 300, antenna radiating surfaces are located on the front, left, and right sides of the system architecture, and all three sides can transmit electromagnetic signals, which corresponds to expanding the antenna aperture.

[0056] It should be noted that the number of radiating surfaces included in the polyplane antenna system provided in this application is not limited. For example, the polyplane antenna system provided in this application may be a two-sided antenna system, a three-sided antenna system, a four-sided antenna system, and so on. It should also be noted that the polyplane antenna system provided in this application may include active antenna units, or may further include passive antenna units, and so on. This is not limited in this application. For ease of explanation, the term “antenna” is used in this application for illustrative purposes.

[0057] Please note that Figures 2 and 3 represent only one of the antenna configurations of the polyplane antenna system architecture provided in this application. The array plane size, element structure, arrangement, etc., used by the front and side radiating antennas of the polyplane antenna system in Figures 2 and 3 are merely examples and are not limited thereto.

[0058] Figure 4 is a diagram of the radiation of the three-sided antenna system 300. As shown in Figure 4, in the three-sided antenna system 300, each radiating surface (each antenna unit) is independently responsible for the coverage of the corresponding cell (or sector). For example, in Figure 4, radiating surface 310 includes antennas 311 and 312, and radiating surface 310 is responsible for the coverage of cell 1 (or, the radiation range of radiating surface 310 is cell 1); radiating surface 320 includes antennas 321 and 322, and radiating surface 320 is responsible for the coverage of cell 2 (or, the radiation range of radiating surface 320 is cell 2); radiating surface 330 includes antennas 331 and 332, and radiating surface 330 is responsible for the coverage of cell 3 (or, the radiation range of radiating surface 330 is cell 3).

[0059] In the three-sided antenna system shown in Figure 4, the transmit power of each cell is configured independently for each radiating surface, and the maximum power of each cell cannot exceed the standard maximum transmit power of the radiating surface from which the cell radiates. For example, if the maximum transmit power of radiating surface 310 is 200W, the maximum power of cell 1 must be 200W or less; if the maximum transmit power of radiating surface 320 is 100W, the maximum power of cell 2 must be 100W or less; if the maximum transmit power of radiating surface 330 is 150W, the maximum transmit power of cell 3 must be 150W or less. However, if some radiating surfaces (e.g., radiating surfaces 310 and 320) do not transmit power, the maximum transmit power of the entire three-sided antenna system is the maximum transmit power of cell 3, i.e., 150W. In this case, if the available transmit power value of the three-sided antenna system is 300W, the maximum transmit power of the entire three-sided antenna system cannot be utilized to its full potential because the maximum transmit power of the antenna system is 150W.

[0060] Therefore, this application provides a multi-faceted antenna system. The power control module is used to configure the power for the entire multi-faceted antenna system and to perform coordination between multiple antennas as well as power sharing and allocation.

[0061] Note that the polyhedron antenna systems provided in this application will be described below using two-sided and three-sided antenna systems (see the descriptions of Figures 2 and 3 for the architectures of the two-sided and three-sided antenna systems, respectively) as examples, with reference to Figures 5 and 6. The polyhedron antenna systems provided in this application are further applicable to four-sided antenna systems and other polyhedron antenna systems, but are not limited to these.

[0062] Figure 5 shows the structure of the two-sided antenna system 500 according to this application.

[0063] As shown in Figure 5, the two-sided antenna system 500 includes a radiating surface 510 and a radiating surface 520. Each radiating surface serves users in its respective area. For example, in Figure 5, radiating surface 510 serves users in area 1, and radiating surface 520 serves users 2 in area 2. Each radiating surface includes at least one antenna unit, and the orientations of the different radiating surfaces are different. For example, in Figure 5, the orientation of radiating surface 510 and radiating surface 520 are different. The antennas on each radiating surface are connected to backend radio frequency channels, and each radio frequency channel includes a power amplification module. For example, in Figure 5, radiating surface 510 includes one antenna 511, and radiating surface 520 includes one antenna 521. Antenna 511 is connected to radio frequency channel 512, which includes a power amplification module 513. Antenna 521 is connected to radio frequency channel 522, which includes a power amplification module 523.

[0064] Please note that the orientation of the antennas on each radiating surface is not limited in this application, and the antenna orientation in Figure 3 is merely an example.

[0065] It should be noted that the radio frequency channel and antenna may be located in the same module (for example, in the form of an active antenna unit (AAU)) or in separate modules (for example, in the form of a remote radio unit (RRU)).

[0066] In one possible implementation, on each radiating surface, both at least one antenna and a radio frequency channel are located inside the active antenna unit.

[0067] In one possible implementation, on each radiating surface, at least one antenna is located inside the passive antenna, and the radio frequency channel is located inside the remote radio unit.

[0068] The two-sided antenna system 500 shown in Figure 5 further includes one power control module 530. The power control module 530 is logically connected to radio frequency channels 512 and 522, respectively. Specifically, based on service requirements, the power control module 530 is used to share and allocate power between the different radiating surfaces within the two-sided antenna system 500.

[0069] It should be understood that the logical connection of the power control module 530 to radio frequency channels 512 and 522, respectively, can be understood as the direct or indirect connection of the power control module 530 to radio frequency channels (radio frequency channels 512 and 522) corresponding to different radiating surfaces (radiating surfaces 510 and 520), respectively. The method of logical connection is not limited in this application.

[0070] It should be noted that the power control module 530 may be located inside or outside the RRU or AAU. This is not limited to the present application.

[0071] The following describes a solution for performing power sharing and allocation between different radiating surfaces in a polyhedral antenna system provided in this application, using a power control module.

[0072] Specifically, we assume that a single polyfaceted antenna system (device) has a total of N radiating surfaces, the maximum transmit power of the standard specification of the polyfaceted antenna system is Ptotal, the transmit power of the radio frequency channel corresponding to the first radiating surface is P1, the transmit power of the radio frequency channel corresponding to the second radiating surface is P2, and the remainder is estimated by analogy. The transmit power of the radio frequency channel corresponding to the Nth radiating surface is PN. In the polyfaceted antenna system, P1 reaches its maximum value P1max at time T1, P2 reaches its maximum value P2max at time T2, and the remainder is estimated by analogy. PN reaches its maximum value PNmax at time TN. T1 to TN are different time points. When a power control module is used to share and allocate the transmit power of N radiating surfaces, at different points in time, the sum of the maximum transmit powers of the different radiating surfaces is greater than the maximum transmit power of the polyplane antenna system, i.e., P1max + P2max + ... + PNmax > Ptotal, and at different points in time, the maximum transmit powers of all the different radiating surfaces are less than or equal to the maximum transmit power of the polyplane antenna system, i.e., P1max ≤ Ptotal, P2max ≤ Ptotal, ..., and PNmax ≤ Ptotal. However, at the same point in time, the sum of the transmit powers of the different radiating surfaces is less than the maximum transmit power of the polyplane antenna system, i.e., P1 + P2 + ... + PN ≤ Ptotal.

[0073] It should be understood that in order to make P1max + P2max + ... + PNmax greater than Ptotal, the power amplification capability of the power amplification module in the radio frequency channel needs to be improved. Therefore, the design specifications of the power amplification module need to be improved, that is, the maximum power amplification capability of the power amplification module needs to be improved. In this way, in the case of a multifaceted antenna system, when the number of radiating surfaces is greater and the power amplification capability of the power amplification module in the radio frequency channel is higher, the power that can support the multifaceted antenna system is shared and allocated among the different radiating surfaces without being limited by the power amplification capability, and the performance of the multifaceted antenna system is improved.

[0074] Specifically, for each of the N radiating surfaces in the polyfaceted antenna system, each radiating surface is connected to at least one radio frequency channel, and each radio frequency channel includes (corresponds to) one power amplification module. In this case, the power amplification capability of at least one power amplification module in the polyfaceted antenna system is greater than the value obtained by dividing the maximum transmit power (Ptotal) of the polyfaceted antenna system by the total number of radio frequency channels in the polyfaceted antenna system.

[0075] To facilitate understanding, a illustrative explanation is provided below using a specific power sharing and allocation solution for the power control module 530 as an example, with reference to Figure 5.

[0076] For example, the standard maximum transmit power of the two-sided antenna system 500 is 200W. Radiating surface 510 corresponds to radio frequency channel 512, which includes power amplification module 513. Radiating surface 520 corresponds to radio frequency channel 522, which includes power amplification module 523. For power amplification modules 513 and 523, the power amplification capability of at least one of the two power amplification modules is greater than the value obtained by dividing the maximum transmit power of the two-sided antenna system 500 (200W) by the total number of radio frequency channels in the two-sided antenna system 500 (2). For example, the power amplification capability of power amplification module 513 is greater than 100W. In another example, the power amplification capability of power amplification module 523 is greater than 100W. In yet another example, both the power amplification capability of power amplification module 513 and the power amplification capability of power amplification module 523 are greater than 100W.

[0077] In the following, for illustrative purposes, we will use an example where the available transmit power value of the two-sided antenna system 500 is 200W, and the maximum transmit power of each radiating surface is also 200W, that is, both the maximum transmit power of radiating surface 510 and the maximum transmit power of radiating surface 520 are 200W.

[0078] For example, at time T1, users in area 1 are receiving communication services, and the service requirement is a transmission power of 200W, but users in area 2 are not receiving communication services. In this case, the power control module 530 controls the radiating surface 510 to transmit 200W of power, and the radiating surface 520 does not transmit power.

[0079] For example, at time T2, users in area 2 are receiving communication services, and the service requirement is a transmission power of 200W, but users in area 1 are not receiving communication services. In this case, the power control module 530 controls the radiating surface 520 to transmit 200W of power, and the radiating surface 510 does not transmit power.

[0080] For example, at time T3, both users in Area 1 and users in Area 2 are receiving communication services, and both the transmit power requirements for users in Area 1 and users in Area 2 are 100W. In this case, the power control module 530 controls the radiating surfaces 510 and 520 to transmit 100W of power, respectively.

[0081] For example, at time T4, both users in Area 1 and users in Area 2 are receiving communication services, and the transmit power for the service requirements corresponding to users in Area 1 and users in Area 2 are 80W and 50W, respectively. The power control module 530 allocates 80W to the radiating surface 510 and 50W to the radiating surface 520 based on the service requirements. In this case, 70W is still unallocated or 70W remains in the available transmit power value of the two-sided antenna system 500 (i.e., the difference between the sum of the service requirements corresponding to the radiating surface 510 and the service requirements corresponding to the radiating surface 520 and the available transmit power value of the two-sided antenna system is 70W). To implement maximum utilization of the transmit power of the two-sided antenna system, the power control module 530 may further allocate the unallocated 70W based on a 1:1 ratio, i.e., the power control module 530 may further allocate 35W to the radiating surface 510 and the radiating surface 520, respectively. In other words, the power control module 530 actually controls the radiating surface 510 to transmit 115W of power and the radiating surface 520 to transmit 85W of power.

[0082] Note that in Figure 5 above, an example is used for illustrative purposes in which each radiating surface is connected to one radio frequency channel. The number of radio frequency channels connected to each radiating surface is not limited in this application.

[0083] In a multifaceted antenna system, if the radiating surface is connected to at least two radio frequency channels, it should be understood that the power amplification capability of a power amplification module included in one of the radio frequency channels must be greater than the value obtained by dividing the maximum transmit power of the multifaceted antenna system by the total number of radio frequency channels included in the multifaceted antenna system. The power amplification capability of a power amplification module included in another radio frequency channel of the radiating surface is not limited.

[0084] Based on the aforementioned power allocation solution, at any given time, the total transmit power of the radiating surfaces within the system will not exceed the system's nominal maximum transmit power. However, at different times, the sum of the maximum transmit powers of different radiating surfaces will exceed the system's nominal maximum transmit power. Therefore, coordination, power sharing, and allocation between multiple radiating surfaces are implemented. If different radiating surfaces serve different cells, power sharing between cells can be implemented.

[0085] Figure 6 is a diagram showing the structure of the three-sided antenna system 600 according to this application.

[0086] As shown in Figure 6, the three-sided antenna system 600 includes radiating surfaces 610, 620, and 630. Each radiating surface serves users in its respective area. For example, in Figure 6, radiating surface 610 serves users in area 1, radiating surface 620 serves users in area 2, and radiating surface 630 serves users in area 3. Each radiating surface includes at least one antenna unit, and the orientations of the different radiating surfaces are not exactly the same (or, in the three radiating surfaces of the three-sided antenna system 600, at least two of the radiating surfaces have different orientations). For example, in Figure 6, radiating surface 610 includes one antenna 611 and one antenna 612, radiating surface 620 includes one antenna 621, and radiating surface 630 includes one antenna 631. The orientation of radiating surface 610 is different from the orientation of radiating surface 620, the orientation of radiating surface 610 is different from the orientation of radiating surface 630, and the orientation of radiating surface 620 is the same as the orientation of radiating surface 630. The antenna on each radiating surface is connected to a backend radio frequency channel, which includes a power amplifier (PA). For example, in Figure 6, both antenna 611 and antenna 612 are connected to radio frequency channel 613, which includes a power amplifier module 614. Antenna 621 is connected to radio frequency channel 622, which includes a power amplifier module 623. Antenna 631 is connected to radio frequency channel 632, which includes a power amplifier module 633.

[0087] It should be understood that the orientations of different radiating surfaces are not exactly the same. In a polyhedral antenna system, at least two radiating surfaces must have different orientations. For example, in Figure 6, the orientations of radiating surface 610 and radiating surface 620 are different, the orientations of radiating surface 610 and radiating surface 630 are different, and the orientations of radiating surface 620 and radiating surface 630 are the same. In one possible implementation, the orientations of radiating surface 610, radiating surface 620, and radiating surface 630 may be different from each other by alternative means. This is not limited to this application.

[0088] It should be noted that the radio frequency channel and antenna may be located in the same module (for example, in the form of an active antenna unit (AAU)) or in separate modules (for example, in the form of a remote radio unit (RRU)).

[0089] The three-sided antenna system 600 shown in Figure 6 further includes one power control module 630. The power control module 630 is logically connected to radio frequency channels 613, 622, and 632, respectively. Specifically, based on service requirements, the power control module 630 is configured to allocate power to the different radiating surfaces within the three-sided antenna system 600.

[0090] It should be understood that the logical connection of the power control module 630 to radio frequency channels 613, 622, and 632, respectively, can be understood as the direct or indirect connection of the power control module 630 to radio frequency channels 613, 622, and 632, respectively, corresponding to different radiating surfaces (radiating surfaces 610, 620, and 630). The method of logical connection is not limited in this application.

[0091] It should be noted that the power control module 630 may be located inside or outside the RRU or AAU. This is not limited to the present application.

[0092] For a detailed explanation of the aforementioned power control module 630, please refer to the relevant explanation of the power control module 530 in Figure 5. To avoid repetition, a detailed explanation is omitted in this specification.

[0093] To facilitate understanding, an illustrative explanation is provided below using a specific power allocation solution for the power control module 630 as an example.

[0094] For example, the nominal maximum transmit power of the three-sided antenna system 600 is 300W. Radiating surface 610 corresponds to radio frequency channel 613, which includes power amplification module 614; radiating surface 620 corresponds to radio frequency channel 622, which includes power amplification module 623; and radiating surface 630 corresponds to radio frequency channel 632, which includes power amplification module 633. For power amplification modules 614, 623, and 633, the power amplification capability of at least one of the three power amplification modules is greater than the value obtained by dividing the maximum transmit power of the three-sided antenna system 600 (600W) by the total number of radio frequency channels in the three-sided antenna system 600 (3). For example, the power amplification capability of power amplification module 614 is greater than 200W. In another example, the power amplification capability of power amplification module 623 is greater than 200W. In another example, the power amplification capability of power amplifier module 633 is greater than 200W. In yet another example, both the power amplification capability of power amplifier module 614 and the power amplification capability of power amplifier module 623 are greater than 200W. In yet another example, the power amplification capability of power amplifier module 614, the power amplification capability of power amplifier module 623, and the power amplification capability of power amplifier module 633 are all greater than 200W.

[0095] For illustrative purposes, the following example uses a three-sided antenna system 600 with a usable transmit power of 300W, where the maximum transmit power of each radiating surface is also 300W; that is, the maximum transmit power of radiating surface 610, radiating surface 620, and radiating surface 630 are all 300W.

[0096] For example, at time T1, users in Area 1 are receiving communication services, and the service requirement is a transmission power of 300W, but users in Area 2 and Area 3 are not receiving communication services. In this case, the power control module controls the radiating surface 610 to transmit 300W of power and radiate surface Surfaces 620 and 630 do not transmit power.

[0097] For example, at time T2, users in Area 2 are receiving communication services, and the service requirement is a transmission power of 300W, but users in Area 1 and Area 3 are not receiving communication services. In this case, the power control module controls the radiating surface 620 to transmit 300W of power, while radiating surfaces 610 and 630 do not transmit power.

[0098] For example, at time T3, users in area 3 are receiving communication services, and the service requirement is a transmission power of 300W, but users in area 1 and area 2 are not receiving communication services. In this case, the power control module controls the radiating surface 630 to transmit 300W of power, while radiating surfaces 610 and 620 do not transmit power.

[0099] For example, at time T4, users in Area 1, Area 2, and Area 3 are all receiving communication services, and the transmit power for the service requirements corresponding to users in Area 1 and the transmit power for the service requirements corresponding to users in Area 2 are both 100W. In this case, the power control module controls radiating surfaces 610, 620, and 630 to transmit 100W of power, respectively.

[0100] For example, at time T5, both users in Area 1 and Area 2 are receiving communication services, and the transmit power requirements for the service requirements corresponding to users in Area 1 and users in Area 2 are 100W and 50W, respectively. Users in Area 3 are not receiving communication services. In this case, the power control module 630 allocates 100W to the radiating surface 510 and 50W to the radiating surface 520 based on the service requirements. In this case, 150W remains unallocated or 150W is still available in the total transmit power of the three-sided antenna system (i.e., the difference between the sum of the service requirements corresponding to radiating surface 510 and radiating surface 520 and the total transmit power of the three-sided antenna system is 150W). To maximize the transmission power utilization of the three-sided antenna system, the power control module 630 may further allocate the unallocated 150W based on a 1:1:1 ratio, i.e., the power control module 630 may further allocate 50W to each of the radiating surfaces 610, 620, and 630. In other words, the power control module 630 actually controls the radiating surface 610 to transmit 150W of power, the radiating surface 620 to transmit 100W of power, and the radiating surface 630 to transmit 50W of power.

[0101] Note that in Figure 6 above, an example is used for illustrative purposes in which each radiating surface is connected to one radio frequency channel. The number of radio frequency channels connected to each radiating surface is not limited in this application.

[0102] Based on the aforementioned power allocation solution, at any given time, the total transmit power of the radiating surfaces within the system will not exceed the system's nominal maximum transmit power. However, at different times, the sum of the maximum transmit powers of different radiating surfaces will exceed the system's nominal maximum transmit power. Therefore, coordination, power sharing, and allocation between multiple radiating surfaces are implemented. If different radiating surfaces serve different cells, power sharing between cells can be implemented.
