Description

A multi-surface antenna system and power allocation method

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 30, 2023, with application number 202310803871.6 and invention name “A Multi-Surface Antenna System and Power Allocation Method”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communications, and in particular to a multi-faceted antenna system and a power allocation method. Background Art

[0003] In wireless communication networks, base stations, as key network nodes, play a key role in communication networks. With the development of mobile communications, the form of base station equipment has also diversified. For example, a multi-surface antenna system architecture is composed of two radiating surfaces (two-surface), three radiating surfaces (three-surface), or multiple radiating surfaces (multi-surface). However, for the multi-surface antenna system architecture, each radiating surface is independently responsible for the coverage of the corresponding cell (or sector), that is, each radiating surface is independently configured with transmission power. In this way, for the entire multi-surface antenna system architecture, when some radiating surfaces do not transmit power, the maximum transmission power of the multi-surface antenna system is the maximum transmission power of the radiating surface that can currently transmit power. If the available transmission power value of the multi-surface antenna system is higher than the current maximum transmission power of the multi-surface antenna system, it is impossible to maximize the transmission power of the entire multi-surface antenna system.

[0004] Summary of the Invention

[0005] The embodiments of the present application provide a multi-aspect antenna system and a power allocation method, which utilizes a power control module to configure the transmission power of the entire multi-aspect antenna system, thereby achieving collaboration and shared power allocation among multiple antennas, thereby maximizing the power utilization of the antenna system.

[0006] In a first aspect, a multi-surface antenna system is provided, comprising: at least two radiating surfaces for radiating signals, wherein each radiating surface includes at least one antenna, each radiating surface is connected to at least one radio frequency channel, and M radiating surfaces of the at least two radiating surfaces have different orientations, where M is a positive integer greater than or equal to 2; a power control module for determining the transmission power of the at least two radiating surfaces based on the available transmission power value of the multi-surface antenna system, the power control module being logically connected to the radio frequency channels corresponding to the at least two radiating surfaces.

[0007] It should be understood that the different orientations of the M radiating surfaces among the at least two radiating surfaces can be understood as meaning that the orientations of the at least two radiating surfaces included in the multi-surface antenna system are not all the same. In other words, at least two radiating surfaces in the multi-surface antenna system have different orientations. In other words, it suffices that at least two of the at least two radiating surfaces included in the multi-surface antenna system have different orientations.

[0008] It should be understood that two radiating surfaces with different directions serve two different cells, or in other words, the two radiating surfaces have different directions and serve different cells.

[0009] Exemplarily, the multi-surface antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2), and the radiating surface #1 and the radiating surface #2 have different orientations.

[0010] Exemplarily, the multi-surface antenna system includes three radiating surfaces (radiating surface #1, radiating surface #2, and radiating surface #3). Radiating surface #1 and radiating surface #2 have the same orientation, and radiating surface #3 has a different orientation from radiating surface #1 and radiating surface #2.

[0011] Exemplarily, the multi-surface antenna system includes three radiating surfaces (radiating surface #1, radiating surface #2, and radiating surface #3), and the directions of radiating surface #1, radiating surface #2, and radiating surface #3 are all different.

[0012] It should be understood that the logical connection between the power control module and the radio frequency channels corresponding to at least two radiating surfaces can be understood as, in a multi-surface antenna system, the radio frequency channels corresponding to at least two radiating surfaces are logically connected to the power control module, or in other words, the power control module is respectively connected to at least two radio frequency channels corresponding to different radiating surfaces. It should be understood that the logical connection between the power control module and the radio frequency channels corresponding to at least two radiating surfaces can be a direct connection or an indirect connection, and this application does not limit the connection method between the power control module and the radio frequency channels corresponding to at least two radiating surfaces.

[0013] It should be understood that the transmission power of a multi-surface antenna system is the power of the signal (electrical signal) input to the multi-surface antenna system that is effectively converted into the electromagnetic wave component at a specific moment. The maximum transmission power (rated transmission power) of a multi-surface antenna system is the maximum transmission power that the multi-surface antenna system can achieve, or in other words, the maximum transmission power that can be achieved by the sum of all the radiating surfaces of the multi-surface antenna system at a given moment. The available transmission power of a multi-surface antenna system is the maximum transmission power of the multi-surface antenna system minus the used transmission power (e.g., the transmission power used for specific needs).

[0014] It should be understood that the available transmit power value of the multi-surface antenna system is less than or equal to the maximum transmit power of the multi-surface antenna system. Generally, the maximum transmit power of the multi-surface antenna system is the available transmit power value of the multi-surface antenna system. In the above scheme, the power of the entire multi-surface antenna system is configured using a power control module, achieving collaboration and power sharing among multiple radiating surfaces. Furthermore, when at least two radiating surfaces in the multi-surface antenna system have different orientations and thus serve users in different areas (or cells), power sharing between different cells can be achieved.

[0015] A possible implementation manner is a power control module for determining the transmission power of at least two radiating surfaces based on the available transmission power value of the multi-surface antenna system, including: a power control module for determining the power amplifier output of the power amplification module corresponding to at least two radiating surfaces based on the available transmission power value of the multi-surface antenna system and the service requirements corresponding to the at least two radiating surfaces.

[0016] For example, a multi-surface antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2). The available transmit power value of the multi-surface antenna system is 300W, and the maximum transmit power of radiating surface #1 and radiating surface #2 are both 200W. The transmit power required by the service corresponding to radiating surface #1 is 100W, and the transmit power required by the service corresponding to radiating surface #2 is 100W. Then, based on the service requirements corresponding to radiating surface #1 and radiating surface #2, the power control module determines that the power amplifier output of the power amplifier module corresponding to radiating surface #1 is 100W, and determines that the power amplifier output of the power amplifier module corresponding to radiating surface #2 is 100W.

[0017] In one possible implementation, the power control module determines a power difference based on the available transmission power value of the multi-surface antenna system and the business requirements corresponding to at least two radiating surfaces, wherein the power difference is the difference between the sum of the business requirements corresponding to the at least two radiating surfaces and the available transmission power value of the multi-surface antenna system; the power control module determines the power amplifier output of the power amplification module corresponding to the at least two radiating surfaces based on the business requirements corresponding to the at least two radiating surfaces and the power difference.

[0018] For example, a multi-surface antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2). The available transmit power value of the multi-surface antenna system is 300W, and the maximum transmit power of both radiating surface #1 and radiating surface #2 is 200W. The transmit power required by the service corresponding to radiating surface #1 is 100W, and the transmit power required by the service corresponding to radiating surface #2 is 200W. The sum of the transmit power requirements of the service corresponding to radiating surface #1 and radiating surface #2 is 300W. At this time, the power difference is 0. Therefore, the power control module determines that the power amplifier output of the power amplifier module corresponding to radiating surface #1 is 100W, and the power amplifier output of the power amplifier module corresponding to radiating surface #2 is 200W.

[0019] Exemplarily, a multi-surface antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2). The available transmit power value of the multi-surface antenna system is 300W, and the maximum transmit power value of both radiating surface #1 and radiating surface #2 is 200W. The transmit power required for the service corresponding to radiating surface #1 is 100W, and the transmit power required for the service corresponding to radiating surface #2 is 150W. The sum of the transmit power requirements for the services corresponding to radiating surfaces #1 and #2 is 250W. At this time, the power difference is 50W (in other words, in addition to meeting the transmit power requirements for the services corresponding to radiating surfaces #1 and #2, the available transmit power value of the multi-surface antenna system still remains at 50W). In this case, the power control module can further allocate the unallocated (remaining) 50W to radiating surface #1 and radiating surface #2.

[0020] It should be understood that when the power control module further allocates the unallocated transmit power to radiation surface #1 and radiation surface #2, it can be allocated according to proportion, service demand, radiation priority, etc., and this application does not limit this.

[0021] For example, the power control module allocates the unallocated 50 W to radiation surface #1 and radiation surface #2 according to a ratio. For example, the power control module allocates 25 W to radiation surface #1 and radiation surface #2 respectively at a ratio of 1:1 (on average). At this time, the power amplifier output of the power amplifier module corresponding to radiation surface #1 includes the sum of the corresponding business demand transmission power (100 W) and the additionally allocated 25 W, that is, 125 W. The power amplifier output of the power amplifier module corresponding to radiation surface #2 includes the sum of the corresponding business demand transmission power (150 W) and the additionally allocated 25 W, that is, 175 W. Alternatively, the power control module redistributes 40W and 10W to radiation surface #1 and radiation surface #2 respectively in a ratio of 4:1. That is, at this time, the power amplifier output of the power amplifier module corresponding to radiation surface #1 includes the sum of the corresponding business demand transmission power (100W) and the additionally allocated 40W, that is, 140W, and the power amplifier output of the power amplifier module corresponding to radiation surface #2 includes the sum of the corresponding business demand transmission power (150W) and the additionally allocated 10W, that is, 160W.

[0022] For another example, the power control module allocates the unallocated 50W to radiation surface #1 and radiation surface #2 according to business needs. If the transmission power of the business demand corresponding to radiation surface #1 is higher than the transmission power of the business demand corresponding to radiation surface #2, then 30W will be allocated to radiation surface #1 and 20W will be allocated to radiation surface #2. That is, at this time, the power amplifier output of the power amplifier module corresponding to radiation surface #1 includes the sum of the transmission power of the corresponding business demand (100W) and the additionally allocated 30W, that is, 130W. The power amplifier output of the power amplifier module corresponding to radiation surface #2 includes the sum of the transmission power of the corresponding business demand (150W) and the additionally allocated 20W, that is, 170W.

[0023] In the above solution, according to specific business needs, the power control module is used to adjust the power amplifier output of the power amplifier module in the multi-surface antenna system, so that multiple radiating surfaces in the multi-surface antenna system can achieve power sharing and distribution.

[0024] It should be understood that in order to avoid the problem that the actual allocated transmission power exceeds the maximum transmission power of the radiation surface when the power control module further allocates the unallocated transmission power to at least two radiation surfaces, it is necessary to improve the power amplification capacity of the power amplifier module in the radio frequency channel corresponding to the radiation surface, so that when the power control module shares the available transmission power value of the multi-surface antenna system among different radiation surfaces, it is not limited by the power amplification capacity of the power amplifier module.

[0025] In one possible implementation, each RF channel includes a power amplifier module, and the power amplification capacity of at least one power amplifier module in the multi-surface antenna system is greater than the maximum transmit power of the multi-surface antenna system divided by the number of RF channels in the multi-surface antenna system. It should be understood that each RF channel includes a power amplifier module, which can be understood as including (corresponding to) a power amplifier (PA) module for amplifying the RF signal and increasing the output power for at least one RF channel corresponding to each of the at least two radiating surfaces included in the multi-surface antenna system.

[0026] It should be understood that in the multi-aspect antenna system, the power amplification capacity of at least one power amplification module is greater than the maximum transmit power of the multi-aspect antenna system divided by the total number of radio frequency channels included in the multi-aspect antenna system.

[0027] Exemplarily, the multi-surface antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2), radiating surface #1 and radiating surface #2 are connected to RF channel #1 and RF channel #2, respectively, and RF channel #1 and RF channel #2 include (corresponding to) power amplifier module #1 and power amplifier module #2, respectively. The maximum transmit power of the multi-surface antenna system is 200W, and the power amplifier capacity of power amplifier module #1 is greater than the maximum transmit power of the multi-surface antenna system (200W) divided by the number of RF channels included in the multi-surface antenna system (2), that is, the power amplifier capacity of power amplifier module #1 is greater than 100W; for another example, the power amplifier capacity of power amplifier module #2 is greater than 100W; for another example, the power amplifier capacity of power amplifier module #1 and power amplifier module #2 are both greater than 100W.

[0028] For example, the multi-surface antenna system includes three radiating surfaces (radiating surface #1, radiating surface #2, and radiating surface #3). Radiating surface #1, radiating surface #2, and radiating surface #3 are connected to RF channel #1, RF channel #2, and RF channel #3, respectively. RF channel #1, RF channel #2, and RF channel #3 include (corresponding to) power amplifier modules #1, power amplifier modules #2, and power amplifier modules #3, respectively. The maximum transmit power of the multi-surface antenna system is 600W. The power amplifier capacity of power amplifier module #1 is greater than the maximum transmit power of the multi-surface antenna system (600W) divided by the number of RF channels included in the multi-surface antenna system (3), that is, the power amplifier capacity of power amplifier module #1 is greater than 200W. For another example, the power amplifier capacity of power amplifier module #1 and power amplifier module #2 are both greater than 200W. For another example, the power amplifier capacity of power amplifier module #1, power amplifier module #2, and power amplifier module #3 are all greater than 200W, and so on.

[0029] It should be noted that this application does not limit the number of RF channels connected to each radiating surface.

[0030] It should be understood that if in a multi-surface antenna system, a certain radiating surface is connected to at least two RF channels, and the power amplification capacity of the power amplification module included in one of the RF channels is greater than the maximum transmission power of the multi-surface antenna system divided by the total number of RF channels included in the multi-surface antenna system, there is no restriction on the power amplification capacity of the power amplification modules included in other RF channels of the radiating surface. For example, the power amplification capacity of the power amplification modules included in other RF channels of the radiating surface may be less than the maximum transmission power of the multi-surface antenna system divided by the total number of RF channels included in the multi-surface antenna system.

[0031] Exemplarily, the multi-surface antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2), radiating surface #1 is connected to RF channel #1 and RF channel #2, radiating surface #2 is connected to RF channel #3, RF channel #1, RF channel #2, and RF channel #3 respectively include (corresponding to) power amplifier module #1, power amplifier module #2, and power amplifier module #3, and the maximum transmission power of the multi-surface antenna system is 300 W. For radiating surface #1, the power amplification capacity of power amplifier module #1 is greater than the maximum transmission power of the multi-surface antenna system (300 W) divided by the number of RF channels included in the multi-surface antenna system (3), that is, the power amplification capacity of power amplifier module #1 is greater than 100 W, and the power amplification capacity of power amplifier module #2 can be less than 100 W; for another example, the power amplification capacity of power amplifier module #1 and power amplifier module #3 are both greater than 100 W.

[0032] In the above scheme, by improving the power amplification capability of the power amplification module included in the RF channel, it is possible to support the flexible sharing and distribution of power of the multi-faceted antenna system among different radiation surfaces without being limited by the power amplification capability, thereby improving the performance of the multi-faceted antenna system.

[0033] In one possible implementation, at least two radiating surfaces include a first radiating surface and a second radiating surface, the first radiating surface has a maximum value of transmission power at a first moment, and the maximum value of the transmission power of the first radiating surface is a first power value, the second radiating surface has a maximum value of transmission power at a second moment, and the maximum value of the transmission power of the second radiating surface is a second power value; the sum of the first power value and the second power value is greater than the maximum transmission power of the multi-surface antenna system, the first power value is less than or equal to the maximum transmission power of the multi-surface antenna system, and the second power value is less than or equal to the maximum transmission power of the multi-surface antenna system.

[0034] In the above scheme, by utilizing the power control module, the sum of the maximum transmission powers of the first radiating surface and the second radiating surface at different times is made greater than the maximum transmission power of the multi-surface antenna system. This avoids the problem of low power utilization caused by the maximum transmission power of the radiating surface at different times not exceeding the maximum transmission power of the antenna system. By sharing and distributing power among multiple radiating surfaces in the multi-surface antenna system, the transmission power of the multi-surface antenna system can be maximized to the greatest extent, thereby improving system performance.

[0035] In one possible implementation, at least two radiating surfaces include a first radiating surface and a second radiating surface, the transmission power of the first radiating surface at the third moment is a third power value, and the transmission power of the second radiating surface at the third moment is a fourth power value; the power control module is also used to share the transmission power of the first radiating surface and the second radiating surface, so that the sum of the third power value and the fourth power value is less than or equal to the maximum transmission power of the multi-surface antenna system.

[0036] In the above solution, by using the power control module, the sum of the transmission powers of the first radiating surface and the second radiating surface at the same time does not exceed the maximum transmission power of the multi-surface antenna system, thereby ensuring the normal operation of the multi-surface antenna system.

[0037] In one possible implementation, in each radiation plane, at least one antenna and a radio frequency channel are located in an active antenna unit; or at least one antenna is located in a passive antenna, and the radio frequency channel is located in a remote radio frequency unit.

[0038] In the above scheme, the antenna included in each radiating surface in the multi-surface antenna system and the RF channel connecting the radiating surface can be located in the same active antenna unit, or can be located in the passive antenna and remote RF unit respectively, which increases the diversity of the physical implementation of the multi-surface antenna system.

[0039] In one possible implementation manner, the power control module is located inside the active antenna unit or the remote radio frequency unit; or, the power control module is located outside the active antenna unit or the remote radio frequency unit.

[0040] In the above solution, the power control module included in the multi-surface antenna system can be located inside or outside the active antenna unit or the remote radio frequency unit, which increases the diversity of physical implementation of the multi-surface antenna system.

[0041] In a second aspect, a power allocation method is provided. The method is applied to a multi-surface antenna system, where the multi-surface antenna system includes at least two radiating surfaces and a power control module.

[0042] The method may include: a power control module determining the transmission power of at least two radiating surfaces based on the available transmission power value of the multi-surface antenna system; the power control module allocating the transmission power of at least two radiating surfaces to the at least two radiating surfaces; wherein each of the at least two radiating surfaces includes at least one antenna, each radiating surface is connected to at least one radio frequency channel, M radiating surfaces of the at least two radiating surfaces have different orientations, M is a positive integer greater than or equal to 2, and the power control module is logically connected to the radio frequency channels corresponding to the at least two radiating surfaces.

[0043] In one possible implementation, the power control module determines the transmission power of at least two radiating surfaces based on the available transmission power value of the multi-surface antenna system, including: the power control module determines the power amplifier output of the power amplification module corresponding to the at least two radiating surfaces based on the available transmission power value of the multi-surface antenna system and the service requirements corresponding to the at least two radiating surfaces.

[0044] In one possible implementation, a power control module determines the power amplifier output of the power amplification module corresponding to at least two radiating surfaces based on the available transmission power value of the multi-surface antenna system and the business requirements corresponding to the at least two radiating surfaces, including: the power control module determines a power difference based on the available transmission power value of the multi-surface antenna system and the business requirements corresponding to the at least two radiating surfaces, where the power difference is the difference between the sum of the business requirements corresponding to the at least two radiating surfaces and the available transmission power value of the multi-surface antenna system; and the power control module determines the power amplifier output of the power amplification module corresponding to the at least two radiating surfaces based on the business requirements corresponding to the at least two radiating surfaces and the power difference.

[0045] In one possible implementation, each radio frequency channel includes a power amplifier module, and a power amplification capability of at least one power amplifier module in the multi-aspect antenna system is greater than a maximum transmit power of the multi-aspect antenna system divided by the number of radio frequency channels of the multi-aspect antenna system.

[0046] In one possible implementation, at least two radiating surfaces include a first radiating surface and a second radiating surface, the first radiating surface has a maximum value of transmission power at a first moment, and the maximum value of the transmission power of the first radiating surface is a first power value, the second radiating surface has a maximum value of transmission power at a second moment, and the maximum value of the transmission power of the second radiating surface is a second power value; the sum of the first power value and the second power value is greater than the maximum transmission power of the multi-surface antenna system, the first power value is less than or equal to the maximum transmission power of the multi-surface antenna system, and the second power value is less than or equal to the maximum transmission power of the multi-surface antenna system.

[0047] In one possible implementation, at least two radiating surfaces include a first radiating surface and a second radiating surface, the transmission power of the first radiating surface at the third moment is a third power value, the transmission power of the second radiating surface at the third moment is a fourth power value, and the sum of the third power value and the fourth power value is less than or equal to the maximum transmission power of the multi-surface antenna system.

[0057] The following explains the terms that may appear in the embodiments of the present application.

[0058] 1. Active antenna

[0059] Active antennas consist of at least an amplifier (such as a power amplifier (PA)), a filter, and a radiating antenna. They integrate the base station's radio frequency (RF) into the antenna itself, using a multi-channel RF signal and antenna array to achieve spatial beamforming and transmit and receive RF signals.

[0060] 2. Passive antenna

[0061] A passive antenna is a radiating element composed entirely of passive components. Typically, a passive antenna system consists of at least a passive radiator (antenna element), passive impedance matching, a passive balun, and passive interconnects (typically 50 ohm or 75 ohm impedance). Passive antennas are typically mounted on a pole, as shown in Figure 1. The pole is mounted on the back, and the passive antenna is mounted on the front, transmitting electromagnetic radiation and signals.

[0062] The terms "first," "second," "third," "fourth," and the like (if any) in the specification and claims of this application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0063] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0064] Figures 2 and 3 are schematic diagrams of a two-sided antenna system 200 and a three-sided antenna system 300, respectively. In Figure 2, two radiating surfaces 210 and 220 form the two-sided antenna system 200. In two-sided antenna system 200, both sides of the system architecture serve as antenna radiating surfaces, transmitting electromagnetic signals. In Figure 3, three radiating surfaces 310, 320, and 330 form the three-sided antenna system 300 (for three cells and one base station). In three-sided antenna system 300, the forward, left, and right sides of the system architecture serve as antenna radiating surfaces, allowing electromagnetic signals to be transmitted from all three sides, effectively expanding the antenna aperture.

[0065] It should be noted that the multi-surface antenna system provided in this application is not limited to the number of radiating surfaces included. For example, the multi-surface antenna system provided in this application can be a two-surface antenna system, a three-surface antenna system, a four-surface antenna system, etc. It should also be noted that the multi-surface antenna system provided in this application can be composed of active antenna units or passive antenna units, etc. This application does not limit this. For ease of description, the term "antenna" is used in this application.

[0066] It should be noted that Figures 2 and 3 are only one of the antenna forms of the multi-aspect antenna system architecture proposed in this application. The array size, array structure, arrangement, etc. used by the forward and side radiating antennas of the multi-aspect antenna system in Figures 2 and 3 are only examples, and this application does not limit this.

[0067] Figure 4 shows a radiation diagram of a three-sided antenna system 300. As shown in Figure 4, for the three-sided antenna system 300, each radiating surface (each antenna element) is independently responsible for the coverage of the corresponding cell (or sector). For example, in Figure 4, radiating surface 310 includes antenna 311 and antenna 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 antenna 321 and antenna 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 antenna 331 and antenna 332, and radiating surface 330 is responsible for the coverage of cell 3 (or the radiation range of radiating surface 330 is cell 3).

[0068] For the three-surface antenna system shown in Figure 4, each radiating surface independently configures the transmit power for its own cell, and the maximum power of each cell cannot exceed the maximum transmit power specified by the standard specifications for the radiating surface radiating that cell. For example, if the maximum transmit power of radiating surface 310 is 200W, the maximum power of cell 1 must be less than or equal to 200W; if the maximum transmit power of radiating surface 320 is 100W, the maximum power of cell 2 must be less than or equal to 100W; and if the maximum transmit power of radiating surface 330 is 150W, the maximum transmit power of cell 3 must be less than or equal to 150W. However, if some of the radiating surfaces (such as radiating surfaces 310 and 320) do not transmit power, the maximum transmit power of the entire three-surface antenna system is the maximum transmit power of cell 3, which is 150W. If the available transmit power of the three-surface antenna system is 300W, then the maximum transmit power of the entire three-surface antenna system cannot be maximized due to the maximum transmit power of 150W.

[0069] To this end, the present application provides a multi-aspect antenna system, which uses a power control module to configure the power of the entire multi-aspect antenna system, thereby achieving collaboration and shared power distribution among multiple antennas.

[0070] It should be noted that for the multi-sided antenna system provided in this application, the following text will be combined with Figures 5 and 6 to illustrate the two-sided antenna system and the three-sided antenna system (the architecture of the two-sided antenna system and the three-sided antenna system can refer to the description of Figures 2 and 3 respectively). The multi-sided antenna system provided in this application can also be applied to multi-sided antenna systems such as four-sided antenna systems, and this application does not limit this.

[0071] FIG5 shows a schematic structural diagram of a two-sided antenna system 500 of the present application.

[0072] As shown in Figure 5 , a 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 user 2 in area 2. Each radiating surface includes at least one antenna element, and different radiating surfaces have different orientations. For example, in Figure 5 , radiating surfaces 510 and 520 have different orientations. The antenna of each radiating surface is connected to a back-end RF channel, and each RF channel includes a power amplifier module. For example, in Figure 5 , radiating surface 510 includes an antenna 511, and radiating surface 520 includes an antenna 521. Antenna 511 is connected to RF channel 512, which includes a power amplifier module 513. Antenna 521 is connected to RF channel 522, which includes a power amplifier module 523.

[0073] It should be noted that the present application does not limit the direction of the antenna on each radiating surface, and the direction of the antenna in FIG3 is only an example.

[0074] It should be noted that the RF channel and antenna can be in the same module (for example, in the form of an active antenna unit (AAU)) or in independent modules (for example, in the form of a remote radio unit (RRU)).

[0075] In a possible implementation manner, in each radiation surface, at least one antenna and a radio frequency channel are both located in an active antenna unit.

[0076] In one possible implementation, in each radiation plane, at least one antenna is located in a passive antenna, and the radio frequency channel is located in a remote radio frequency unit.

[0077] The two-sided antenna system 500 shown in FIG5 also includes a power control module 530, which is logically connected to RF channel 512 and RF channel 522. Specifically, power control module 530 is used to share and distribute power to different radiating surfaces in the two-sided antenna system 500 based on service requirements.

[0078] It should be understood that the power control module 530 is logically connected to the RF channel 512 and the RF channel 522, respectively. It can be understood that the power control module 530 is directly or indirectly connected to the RF channels (RF channel 512 and RF channel 522) corresponding to different radiation surfaces (radiation surface 510, radiation surface 520), respectively. This application does not limit the connection method of the logical connection.

[0079] It should be noted that the power control module 530 can be inside the RRU or AAU, or outside the RRU or AAU, and this application does not limit this.

[0080] The following describes a solution for sharing and allocating power to different radiating surfaces using a power control module in the multi-surface antenna system provided by this application.

[0081] Specifically, assume a multi-surface antenna system (device) has a total of N radiating surfaces. The standard maximum transmit power of the multi-surface antenna system is Ptotal, where the transmit power of the RF channel corresponding to the first radiating surface is P1, the transmit power of the RF channel corresponding to the second radiating surface is P2, and so on. The transmit power of the RF channel corresponding to the Nth radiating surface is PN. At time T1, P1 of the multi-surface antenna system reaches its maximum value, P1max. At time T2, P2 reaches its maximum value, P2max. And so on, PN reaches its maximum value, PNmax, at time TN, where T1-TN are different times. When the power control module is used to share and allocate the transmit power of the N radiating surfaces, the sum of the maximum transmit powers of the different radiating surfaces is greater than the maximum transmit power of the multi-surface antenna system at different times, that is, P1max+P2max+…+PNmax>Ptotal, and the maximum transmit powers of the different radiating surfaces are all less than or equal to the maximum transmit power of the multi-surface antenna system at different times, that is, P1max≤Ptotal, P2max≤Ptotal, …, PNmax≤Ptotal, and at the same time, the sum of the transmit powers of the different radiating surfaces is less than the maximum transmit power of the multi-surface antenna system, that is, P1+P2+…+PN≤Ptotal.

[0082] It should be understood that in order to make P1max+P2max+…+PNmax>Ptotal, it is necessary to improve the power amplification capacity of the power amplification module in the RF channel. Therefore, it is necessary to improve the design specifications of the power amplification module, that is, to increase the maximum power amplification capacity of the power amplification module. In this way, for a multi-faceted antenna system, the more radiation surfaces there are and the higher the power amplification capacity of the power amplification module in the RF channel, the power of the multi-faceted antenna system can be shared and distributed among different radiation surfaces without being limited by the power amplification capacity, thereby improving the performance of the multi-faceted antenna system.

[0083] Specifically, for the N radiating surfaces in the multi-faceted antenna system, each radiating surface is connected to at least one RF channel, and each RF channel includes (corresponds to) a power amplifier module. Then, the power amplification capacity of at least one power amplifier module in the multi-faceted antenna system is greater than the maximum transmission power (Ptotal) of the multi-faceted antenna system divided by the total number of RF channels of the multi-faceted antenna system.

[0084] For ease of understanding, the specific power sharing allocation scheme of the power control module 530 is exemplarily described below with reference to FIG. 5 .

[0085] For example, the maximum transmission power of the standard specification of the two-sided antenna system 500 is 200W. The radiating surface 510 corresponds to the RF channel 512, and the RF channel 512 includes a power amplifier module 513. The radiating surface 520 corresponds to the RF channel 522, and the RF channel 522 includes a power amplifier module 523. For the power amplifier module 513 and the power amplifier module 523, the power amplification capacity of at least one of the power amplifier modules is greater than the maximum transmission power (200W) of the two-sided antenna system 500 divided by the total number of RF channels of the two-sided antenna system 500 (2). For example, the power amplification capacity of the power amplifier module 513 is greater than 100W; for another example, the power amplification capacity of the power amplifier module 523 is greater than 100W; for another example, the power amplification capacity of the power amplifier module 513 and the power amplifier module 523 are both greater than 100W.

[0086] The following description is made by taking as an example that the available transmission power value of the two-sided antenna system 500 is 200W, and the independent maximum transmission power of each radiating surface is also 200W, that is, the maximum transmission power of the radiating surface 510 and the radiating surface 520 are both 200W.

[0087] For example, at time T1, users in area 1 have communication services with a required transmission power of 200W, while users in area 2 do not have communication services. At this time, the power control module 530 controls the radiation surface 510 to transmit power of 200W, while the radiation surface 520 does not transmit power.

[0088] For example, at time T2, users in area 2 have communication services with a required transmission power of 200W, while users in area 1 do not have communication services. At this time, the power control module 530 controls the radiation surface 520 to transmit power of 200W, while the radiation surface 510 does not transmit power.

[0089] For example, at time T3, users in area 1 and area 2 both have communication services, and the transmission power required by the services of users in area 1 and area 2 is both 100W. At this time, the power control module 530 controls the transmission power of the radiation surface 510 and the radiation surface 520 to be 100W respectively.

[0090] For example, at time T4, users in area 1 and area 2 both have communication services. The transmission powers required by the services for users in area 1 and 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. At this time, 70W of the available transmission power value of the two-sided antenna system 500 is still unallocated or remains (i.e., the difference between the sum of the service requirements corresponding to the radiating surface 510 and the radiating surface 520 and the available transmission power value of the two-sided antenna system is 70W). To maximize the utilization of the transmission power of the two-sided antenna system, the power control module 530 can further allocate 35W of the unallocated 70W to the radiating surface 510 and the radiating surface 520 in a 1:1 ratio. That is, the actual power control module 530 controls the transmission power of the radiating surface 510 to 115W and the transmission power of the radiating surface 520 to 85W.

[0091] It should be noted that FIG5 above illustrates an example in which each radiating surface is connected to one RF channel. The present application does not limit the number of RF channels connected to each radiating surface.

[0092] It should be understood that if in a multi-surface antenna system, a certain radiating surface is connected to at least two RF channels, and the power amplification capacity of the power amplification module included in one of the RF channels is greater than the maximum transmission power of the multi-surface antenna system divided by the total number of RF channels included in the multi-surface antenna system, there is no restriction on the power amplification capacity of the power amplification modules included in other RF channels of the radiating surface.

[0093] Based on this power allocation scheme, at any given moment, the total transmit power of each radiating surface in the system does not exceed the system's nominal maximum transmit power. However, at different moments, the sum of the maximum transmit powers of different radiating surfaces may exceed the system's nominal maximum transmit power. This enables collaboration and shared power allocation among multiple radiating surfaces. When different radiating surfaces serve different cells, power sharing between cells is possible.

[0094] FIG6 shows a schematic structural diagram of a three-sided antenna system 600 of the present application.

[0095] As shown in FIG6 , a three-sided antenna system 600 includes a radiating surface 610, a radiating surface 620, and a radiating surface 630. Each radiating surface serves users in its own area. For example, in FIG6 , 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 element, and the orientations of the different radiating surfaces are not all the same (in other words, at least two of the three radiating surfaces of the three-sided antenna system 600 have different orientations). For example, in FIG6 , radiating surface 610 includes an antenna 611 and an antenna 612, radiating surface 620 includes an antenna 621, and radiating surface 630 includes an antenna 631. Radiating surface 610 and radiating surface 620 have different orientations, radiating surface 610 and radiating surface 630 have different orientations, and radiating surface 620 and radiating surface 630 have the same orientation. The antenna of each radiating surface is connected to the RF channel at the rear end, and the RF channel includes a power amplifier module (PA). For example, in Figure 6, antenna 611 and antenna 612 are both connected to RF channel 613, RF channel 613 includes a power amplifier module 614, antenna 621 is connected to RF channel 622, RF channel 622 includes a power amplifier module 623, and antenna 631 is connected to RF channel 632, and RF channel 632 includes a power amplifier module 633.

[0096] It should be understood that the orientations of different radiating surfaces are not necessarily identical. It is sufficient that at least two radiating surfaces included in the multi-surface antenna system have different orientations. For example, in addition to the different orientations of radiating surface 610 and radiating surface 620, and the different orientations of radiating surface 610 and radiating surface 630, as shown in FIG6 , and the same orientations of radiating surface 620 and radiating surface 630, in one possible embodiment, the orientations of radiating surface 610, radiating surface 620, and radiating surface 630 may also be different from each other, and this application is not limited thereto.

[0097] It should be noted that the RF channel and antenna can be in the same module (for example, in the form of an active antenna unit (AAU)) or in independent modules (for example, in the form of a remote radio unit (RRU)).

[0098] The three-sided antenna system 600 shown in FIG6 also includes a power control module 630, which is logically connected to RF channel 613, RF channel 622, and RF channel 632. Specifically, power control module 630 is used to distribute power to different radiating surfaces in the three-sided antenna system 600 based on service requirements.

[0099] It should be understood that the power control module 630 is logically connected to the RF channel 613, the RF channel 622, and the RF channel 632, respectively. It can be understood that the power control module 630 is directly or indirectly connected to the RF channel 613, the RF channel 622, and the RF channel 632 corresponding to different radiation surfaces (radiation surface 610, radiation surface 620, radiation surface 630), respectively. This application does not limit the connection method of the logical connection.

[0100] It should be noted that the power control module 630 can be inside the RRU or AAU, or outside the RRU or AAU, and this application does not limit this.

[0101] It should be noted that, for the relevant description of the power control module 630 , reference may be made to the relevant description of the power control module 530 in FIG5 , and in order to avoid redundancy, the detailed description thereof is omitted here.

[0102] For ease of understanding, the specific power allocation scheme of the power control module 630 is exemplified below.

[0103] For example, the nominal maximum transmission power of the three-sided antenna system 600 is 300W. The radiating surface 610 corresponds to the RF channel 613, which includes a power amplifier module 614; the radiating surface 620 corresponds to the RF channel 622, which includes a power amplifier module 623; and the radiating surface 630 corresponds to the RF channel 632, which includes a power amplifier module 633. For the power amplifier module 614, the power amplifier module 623, and the power amplifier module 633, the power amplification capacity of at least one of the power amplifier modules is greater than the maximum transmission power (600W) of the three-sided antenna system 600 divided by the total number of RF channels (3) of the three-sided antenna system 600. For example, the power amplification capacity of the power amplification module 614 is greater than 200W; for another example, the power amplification capacity of the power amplification module 623 is greater than 200W; for another example, the power amplification capacity of the power amplification module 633 is greater than 200W; for another example, the power amplification capacity of the power amplification module 614 and the power amplification module 623 are both greater than 200W; for another example, the power amplification capacity of the power amplification module 614, the power amplification module 623 and the power amplification module 633 are all greater than 200W, and so on.

[0104] The following description uses an example in which the available transmission power value of the three-surface antenna system 600 is 300W, and the maximum transmission power of each radiating surface is also 300W, that is, the maximum transmission power of the radiating surface 610, the radiating surface 620, and the radiating surface 630 are all 300W.

[0105] For example, at time T1, users in area 1 have communication services, and the transmission power required by the services is 300W, while users in area 2 and area 3 do not have communication services. At this time, the power control module controls the radiation surface 610 to transmit power of 300W, while radiation 620 and radiation surface 630 do not transmit power.

[0106] For example, at time T2, users in area 2 have communication services, and the transmission power required by the services is 300W, while users in area 1 and area 3 do not have communication services. At this time, the power control module controls the radiation surface 620 to transmit power of 300W, while the radiation surface 610 and the radiation surface 630 do not transmit power.

[0107] For example, at time T3, users in area 3 have communication services, and the transmission power required by the services is 300W, while users in area 1 and area 2 do not have communication services. At this time, the power control module controls the radiation surface 630 to transmit power of 300W, while the radiation surfaces 610 and 620 do not transmit power.

[0108] For example, at time T4, users in area 1, area 2, and area 3 all have communication services, and the transmission power corresponding to the service requirements of users in area 1 and users in area 2 is 100W. At this time, the power control module controls the transmission power of radiation surface 610, radiation surface 620, and radiation surface 630 to 100W respectively.

[0109] For example, at time T5, users in area 1 and users in area 2 both have communication services, and the transmission powers corresponding to the service requirements of users in area 1 and users in area 2 are 100W and 50W respectively. Users in area 3 do not have communication services. At this time, the power control module 630 allocates 100W to the radiation surface 510 and 50W to the radiation surface 520 according to the service requirements. At this time, there is still 150W of unallocated or remaining 150W in the available transmission power value of the three-sided antenna system (that is, the difference between the sum of the service requirements corresponding to the radiation surface 510 and the radiation surface 520 and the available transmission power value of the three-sided antenna system is 150W). In order to maximize the utilization of the transmission power of the three-sided antenna system, the power control module 630 can further allocate 50W of the unallocated 150W to the radiation surface 610, the radiation surface 620, and the radiation surface 630 in a ratio of 1:1:1, that is, the actual power control module 630 controls the radiation surface 610 to transmit 150W, controls the radiation surface 620 to transmit 100W, and controls the radiation surface 630 to transmit 50W.

[0110] It should be noted that FIG6 is taken as an example in which each radiating surface is connected to one RF channel. The present application does not limit the number of RF channels connected to each radiating surface.

[0111] Based on this power allocation scheme, at any given moment, the total transmit power of each radiating surface in the system does not exceed the system's nominal maximum transmit power. However, at different moments, the sum of the maximum transmit powers of different radiating surfaces may exceed the system's nominal maximum transmit power. This enables collaboration and shared power allocation among multiple radiating surfaces. When different radiating surfaces serve different cells, power sharing between cells is possible.

[0112] It should be understood that the multi-faceted antenna system shown in FIG. 5 and FIG. 6 may be a base station, or other communication equipment having the same or similar functions as a base station, etc., and this application does not limit this.
