Description

Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to a multi-aspect antenna system and a power allocation method. Background Art

[0002] 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, such as a multi-surface antenna system architecture composed of two radiating surfaces (two surfaces), three radiating surfaces (three surfaces) or multiple radiating surfaces (multi-surfaces). 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 maximum transmission power of the current multi-surface antenna system at this time, it is impossible to maximize the transmission power of the entire multi-surface antenna system. Summary of the invention

[0003] The embodiment of the present application provides a multi-aspect antenna system and a power allocation method, which uses a power control module to configure the transmission power of the entire multi-aspect antenna system, realizes collaboration and shared power allocation between multiple antennas, and thus realizes maximum power utilization of the antenna system.

[0004] In a first aspect, a multi-surface antenna system is provided, comprising: at least two radiating surfaces for radiating signals, wherein each radiating surface comprises at least one antenna, each radiating surface is connected to at least one radio frequency channel, and M radiating surfaces of at least two radiating surfaces have different orientations, and M is a positive integer greater than or equal to 2; a power control module, for determining the transmission power of at least two radiating surfaces according to the available transmission power value of the multi-surface antenna system, and the power control module is logically connected to the radio frequency channels corresponding to the at least two radiating surfaces.

[0005] It should be understood that the different orientations of the M radiation surfaces among the at least two radiation surfaces can be understood as the orientations of the at least two radiation surfaces included in the multi-surface antenna system are not all the same. In other words, the orientations of at least two radiation surfaces in the multi-surface antenna system are different. In other words, it is sufficient as long as two radiation surfaces among the at least two radiation surfaces included in the multi-surface antenna system have different orientations.

[0006] 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.

[0007] 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.

[0008] 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.

[0009] 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.

[0010] 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 the radio frequency channels corresponding to at least two radiating surfaces in the multi-surface antenna system 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 the present application does not limit the connection method between the power control module and the radio frequency channels corresponding to at least two radiating surfaces.

[0011] It should be understood that the transmission power of the multi-surface antenna system is the power of the signal (electrical signal) input to the multi-surface antenna system at a certain moment that is effectively converted into the electromagnetic wave part. The maximum transmission power (rated transmission power) of the multi-surface antenna system is the maximum value that the transmission power of the multi-surface antenna system can reach, or the maximum value that the sum of the transmission powers of all the radiating surfaces included in the multi-surface antenna system can reach at the same time. The available transmission power value of the multi-surface antenna system is the maximum transmission power of the multi-surface antenna system minus the used transmission power (for example, the transmission power used under specific needs).

[0012] It should be understood that the available transmit power value of the multi-faceted antenna system is less than or equal to the maximum transmit power of the multi-faceted antenna system. In general, the maximum transmit power of the multi-faceted antenna system is the available transmit power value of the multi-faceted antenna system. In the above scheme, the power of the entire multi-faceted antenna system is configured using a power control module, thereby achieving collaboration between multiple radiating surfaces and shared power allocation. Furthermore, when at least two radiating surfaces in the multi-faceted antenna system have different orientations and thus serve users in different areas (or cells), power sharing between different cells can be achieved.

[0013] A possible implementation manner, a power control module is used to determine the transmission power of at least two radiating surfaces according to the available transmission power value of the multi-surface antenna system, including: a power control module is used to determine the power amplifier output of the power amplification module corresponding to at least two radiating surfaces according to the available transmission power value of the multi-surface antenna system and the business requirements corresponding to the at least two radiating surfaces.

[0014] Exemplarily, the multi-surface antenna system includes two radiating surfaces (radiating surface #1, radiating surface #2), the available transmission power value of the multi-surface antenna system is 300W, and the maximum transmission power of the radiating surface #1 and the radiating surface #2 are both 200W. The transmission power of the service demand corresponding to the radiating surface #1 is 100W, and the transmission power of the service demand corresponding to the radiating surface #2 is 100W. Then, the power control module determines that the power amplifier output of the power amplifier module corresponding to the radiating surface #1 is 100W, and determines that the power amplifier output of the power amplifier module corresponding to the radiating surface #2 is 100W according to the service demand corresponding to the radiating surface #1 and the service demand corresponding to the radiating surface #2.

[0015] In a possible implementation manner, a power control module determines a power difference based on an available transmit power value of the multi-surface antenna system and business demands corresponding to at least two radiating surfaces, wherein the power difference is the difference between the sum of the business demands corresponding to at least two radiating surfaces and the available transmit 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 at least two radiating surfaces based on the business demands corresponding to at least two radiating surfaces and the power difference.

[0016] Exemplarily, the multi-surface antenna system includes two radiating surfaces (radiating surface #1, radiating surface #2), the available transmission power value of the multi-surface antenna system is 300W, and the maximum transmission power of the radiating surface #1 and the radiating surface #2 are both 200W. The transmission power of the service demand corresponding to the radiating surface #1 is 100W, the transmission power of the service demand corresponding to the radiating surface #2 is 200W, and the sum of the transmission power of the service demand corresponding to the radiating surface #1 and the radiating surface #2 is 300W. At this time, the power difference is 0, and the power amplifier output of the power amplifier module corresponding to the radiating surface #1 determined by the power control module is 100W, and the power amplifier output of the power amplifier module corresponding to the radiating surface #2 is determined to be 200W.

[0017] Exemplarily, the multi-surface antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2), the available transmission power value of the multi-surface antenna system is 300W, and the maximum transmission power of both radiating surface #1 and radiating surface #2 is 200W. The transmission power of the service demand corresponding to radiating surface #1 is 100W, the transmission power of the service demand corresponding to radiating surface #2 is 150W, and the sum of the transmission power of the service demand corresponding to radiating surface #1 and radiating surface #2 is 250W. At this time, the power difference is 50W (or, at this time, in addition to satisfying the transmission power of the service demand corresponding to radiating surface #1 and radiating surface #2, the available transmission power value of the multi-surface antenna system still has 50W left), then the power control module can 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 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.

[0019] For example, the power control module allocates the unallocated 50W to radiation surface #1 and radiation surface #2 according to the ratio. For example, the power control module allocates 25W 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 (100W) and the additionally allocated 25W, that is, 125W. 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 25W, that is, 175W. Alternatively, the power control module reallocates 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.

[0020] 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. 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, and 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.

[0021] In the above solution, according to the needs of specific services, 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.

[0022] It should be understood that in order to avoid the problem that the actual allocated transmit power exceeds the maximum transmit power of the radiating surface when the power control module further allocates the unallocated transmit power to at least two radiating surfaces, it is necessary to increase the power amplification capacity of the power amplifier module in the RF channel corresponding to the radiating surface, so that when the power control module shares the available transmit power value of the multi-surface antenna system among different radiating surfaces, it is not limited by the power amplification capacity of the power amplifier module.

[0023] In a 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 transmission power of the multi-surface antenna system divided by the number of RF channels of the multi-surface antenna system. It should be understood that each RF channel includes a power amplifier module, which can be understood as at least two radiating surfaces included in the multi-surface antenna system, and at least one RF channel corresponding to each radiating surface includes (corresponds to) a power amplifier module (PA) for amplifying the RF signal and increasing the output power.

[0024] 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 transmission power of the multi-aspect antenna system divided by the total number of radio frequency channels included in the multi-aspect antenna system.

[0025] Exemplarily, the multi-faceted antenna system includes two radiating surfaces (radiating surface #1 and radiating surface #2), and the radiating surface #1 and radiating surface #2 are connected to the RF channel #1 and RF channel #2, respectively, and the RF channel #1 and RF channel #2 include (corresponding to) power amplifier module #1 and power amplifier module #2, respectively. The maximum transmission power of the multi-faceted antenna system is 200W, and the power amplifier capacity of the power amplifier module #1 is greater than the maximum transmission power (200W) of the multi-faceted antenna system divided by the number of RF channels (2) included in the multi-faceted antenna system, that is, the power amplifier capacity of the power amplifier module #1 is greater than 100W; for another example, the power amplifier capacity of the power amplifier module #2 is greater than 100W; for another example, the power amplifier capacity of the power amplifier module #1 and the power amplifier module #2 are both greater than 100W.

[0026] Exemplarily, the multi-faceted antenna system includes three radiating surfaces (radiating surface #1, radiating surface #2, radiating surface #3), radiating surface #1, radiating surface #2, radiating surface #3 are respectively connected to RF channel #1, RF channel #2, RF channel #3, and RF channel #1, RF channel #2, RF channel #3 respectively include (corresponding to) power amplifier module #1, power amplifier module #2, power amplifier module #3. The maximum transmission power of the multi-faceted antenna system is 600W, and the power amplifier capacity of the power amplifier module #1 is greater than the maximum transmission power (600W) of the multi-faceted antenna system divided by the number of RF channels (3) included in the multi-faceted antenna system, that is, the power amplifier capacity of the power amplifier module #1 is greater than 200W; for another example, the power amplifier capacity of the power amplifier module #1 and the power amplifier module #2 are both greater than 200W; for another example, the power amplifier capacity of the power amplifier module #1, the power amplifier module #2, and the power amplifier module #3 are all greater than 200W, and so on.

[0027] It should be noted that the present application does not limit the number of RF channels connected to each radiating surface.

[0028] It should be understood that if in a multi-faceted 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-faceted antenna system divided by the total number of RF channels included in the multi-faceted antenna system, the power amplification capacity of the power amplification modules included in other RF channels of the radiating surface is not restricted. 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-faceted antenna system divided by the total number of RF channels included in the multi-faceted antenna system.

[0029] Exemplarily, the multi-faceted antenna system includes two radiating surfaces (radiating surface #1, 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-faceted antenna system is 300 W. For radiating surface #1, the power amplifier capacity of power amplifier module #1 is greater than the maximum transmission power (300 W) of the multi-faceted antenna system divided by the number of RF channels (3) included in the multi-faceted antenna system, that is, the power amplifier capacity of power amplifier module #1 is greater than 100 W, and the power amplifier capacity of power amplifier module #2 may be less than 100 W; for another example, the power amplifier capacities of power amplifier module #1 and power amplifier module #3 are both greater than 100 W.

[0030] In the above scheme, by improving the power amplification capacity of the power amplification module included in the RF channel, it is possible to support flexible sharing and distribution of power of the multi-faceted antenna system among different radiation surfaces without being limited by the power amplification capacity, thereby improving the performance of the multi-faceted antenna system.

[0031] In a possible implementation manner, 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.

[0032] 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 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.

[0033] In a 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 a 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.

[0034] In the above solution, by using the power control module, the sum of the transmission power of the first radiation surface and the second radiation 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.

[0035] In a possible implementation manner, in each radiation surface, 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.

[0036] 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 a passive antenna and a remote RF unit respectively, which increases the diversity of the physical implementation of the multi-surface antenna system.

[0037] In a 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.

[0038] In the above solution, the power control module included in the multi-faceted antenna system can be located inside or outside the active antenna unit or the remote radio frequency unit, which increases the diversity of the physical implementation of the multi-faceted antenna system.

[0039] In a second aspect, a power allocation method is provided. The method is applied to a multi-surface antenna system. The multi-surface antenna system includes at least two radiating surfaces and a power control module.

[0040] The method may include: a power control module determines the transmission power of at least two radiating surfaces according to the available transmission power value of the multi-surface antenna system; the power control module allocates 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.

[0041] In a possible implementation, a 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 business requirements corresponding to the at least two radiating surfaces.

[0042] In a possible implementation manner, a power control module determines the power amplifier output of the power amplifier module corresponding to at least two radiating surfaces according to 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 according to the available transmission power value of the multi-surface antenna system and the business requirements corresponding to the at least two radiating surfaces, the power difference being 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 amplifier module corresponding to the at least two radiating surfaces according to the business requirements corresponding to the at least two radiating surfaces and the power difference.

[0043] In a possible implementation, each radio frequency channel includes a power amplifier module, and a power amplification capacity of at least one power amplifier module in the multi-aspect antenna system is greater than a maximum transmission power of the multi-aspect antenna system divided by the number of radio frequency channels of the multi-aspect antenna system.

[0055] The following explains the terms that may appear in the embodiments of the present application.

[0056] 1. Active antenna

[0057] An active antenna includes at least an amplifier (such as a power amplifier (PA)), a filter, and a radiating antenna. The active antenna integrates the RF part of the base station into the antenna, uses multi-channel RF and antenna elements to achieve spatial beamforming, and completes the transmission and reception of RF signals.

[0058] 2. Passive antenna

[0059] Passive antennas are radiating elements that are composed entirely of passive components. Typically, a passive antenna system is a system that includes at least a passive radiator (antenna element), passive impedance matching, a passive balun, and a passive interconnect (usually 50Ohm or 75Ohm impedance). Passive antennas are usually mounted on poles, such as Figure 1 As shown, the back is a pole and the front is a passive antenna for electromagnetic radiation and signal transmission.

[0060] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be 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, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0061] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0062] Figure 2 and Figure 3 They are schematic diagrams of a two-sided antenna system 200 and a three-sided antenna system 300. Figure 2 In the embodiment, two radiating surfaces 210 and 220 constitute a two-sided antenna system 200. In the two-sided antenna system 200, both sides of the system architecture are antenna radiating surfaces for emitting electromagnetic signals. Figure 3 In the figure, three radiating surfaces 310, 320 and 330 constitute a three-sided antenna system 300 (three cells and one base station). In the three-sided antenna system 300, the front, left and right sides of the system architecture are all antenna radiating surfaces. Electromagnetic signals can be emitted from the three surfaces, which effectively expands the antenna aperture.

[0063] It should be noted that the multi-surface antenna system provided in the present application is not limited to the number of radiating surfaces included. For example, the multi-surface antenna system provided in the present application may 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 the present application may be composed of active antenna units, passive antenna units, etc., and the present application does not limit this. For the sake of ease of description, in the present application, "antenna" is used for description.

[0064] It should be noted that Figure 2 and Figure 3This is only one of the antenna forms of the multi-faceted antenna system architecture proposed in this application. Figure 2 and Figure 3 The array size, array structure, arrangement, etc. used by the forward and side radiating antennas in the multi-surface antenna system are only examples and are not limited in this application.

[0065] Figure 4 FIG. 3 shows a radiation diagram of a three-sided antenna system 300. Figure 4 As shown, for the three-sided antenna system 300, each radiating surface (each antenna unit) is independently responsible for the coverage of the corresponding cell (or sector). Figure 4 In the figure, the radiation surface 310 includes antenna 311 and antenna 312, and the radiation surface 310 is responsible for the coverage of cell 1 (or the radiation range of the radiation surface 310 is cell 1); the radiation surface 320 includes antenna 321 and antenna 322, and the radiation surface 320 is responsible for the coverage of cell 2 (or the radiation range of the radiation surface 320 is cell 2); the radiation surface 330 includes antenna 331 and antenna 332, and the radiation surface 330 is responsible for the coverage of cell 3 (or the radiation range of the radiation surface 330 is cell 3).

[0066] For Figure 4 In the three-surface antenna system shown, each radiating surface independently configures the transmission power of its own cell, and the maximum power of each cell cannot exceed the maximum transmission power of the standard specification of the radiating surface radiating the cell. For example, if the maximum transmission power of the radiating surface 310 is 200W, the maximum power of cell 1 needs to be less than or equal to 200W; if the maximum transmission power of the radiating surface 320 is 100W, the maximum power of cell 2 needs to be less than or equal to 100W; if the maximum transmission power of the radiating surface 330 is 150W, the maximum transmission power of cell 3 needs to be less than or equal to 150W. However, when some of the radiating surfaces (such as the radiating surface 310 and the radiating surface 320) do not transmit power, the maximum transmission power of the entire three-surface antenna system is the maximum transmission power of cell 3, 150W. If the available transmission power value of the three-surface antenna system is 300W at this time, for the entire three-surface antenna system, since the maximum transmission power is 150W, it is impossible to maximize the transmission power of the antenna system.

[0067] 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 between multiple antennas and shared power allocation.

[0068] It should be noted that for a multi-surface antenna system provided in this application, the following Figure 5 and Figure 6 , respectively, with two-sided antenna system and three-sided antenna system (the architecture of the two-sided antenna system and the three-sided antenna system can be referred to Figure 2 and Figure 3 The multi-aspect antenna system provided in the present application is described as an example, and the multi-aspect antenna system provided in the present application can also be applied to multi-aspect antenna systems such as a four-aspect antenna system, and the present application is not limited to this.

[0069] Figure 5 A schematic structural diagram of a two-sided antenna system 500 of the present application is shown.

[0070] like Figure 5 As shown, the two-sided antenna system 500 includes a radiating surface 510 and a radiating surface 520, each radiating surface serves users in its own area, for example Figure 5 In the example, radiation surface 510 serves users in area 1, and radiation surface 520 serves user 2 in area 2. Each radiation surface includes at least one antenna unit, and different radiation surfaces have different orientations. Figure 5 In the embodiment, the radiation surface 510 and the radiation surface 520 are oriented in different directions. The antenna of each radiation surface is connected to the RF channel at the back end, and each RF channel includes a power amplifier module, such as Figure 5 In the figure, the radiation surface 510 includes an antenna 511, the radiation surface 520 includes an antenna 521, the antenna 511 is connected to the RF channel 512, the RF channel 512 includes a power amplifier module 513, the antenna 521 is connected to the RF channel 522, and the RF channel 522 includes a power amplifier module 523.

[0071] It should be noted that this application does not limit the direction of the antenna on each radiating surface. Figure 3 The directions of the antennas are only examples.

[0072] It should be noted that the radio frequency channel and the antenna may be 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)).

[0073] In a possible implementation manner, in each radiation surface, at least one antenna and a radio frequency channel are located in an active antenna unit.

[0074] In a possible implementation manner, in each radiation surface, at least one antenna is located in a passive antenna, and the radio frequency channel is located in a remote radio frequency unit.

[0075] exist Figure 5 The two-sided antenna system 500 shown also includes a power control module 530, which is logically connected to the RF channel 512 and the RF channel 522. Specifically, according to business requirements, the power control module 530 is used to share and allocate the power of different radiating surfaces in the two-sided antenna system 500.

[0076] 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. The present application does not limit the connection method of the logical connection.

[0077] It should be noted that the power control module 530 may be inside the RRU or AAU, or outside the RRU or AAU, and this application does not limit this.

[0078] The following introduces a solution for sharing and allocating power to different radiating surfaces using a power control module in the multi-surface antenna system provided by the present application.

[0079] Specifically, assuming that a multi-surface antenna system (device) has a total of N radiating surfaces, the maximum transmission power P of the standard specification of the multi-surface antenna system is total , where the transmission power of the RF channel corresponding to the first radiation surface is P1, the transmission power of the RF channel corresponding to the second radiation surface is P2, and so on. The transmission power of the RF channel corresponding to the Nth radiation surface is P N The multi-surface antenna system reaches its maximum value P at time T1. 1max At time T2, P2 reaches its maximum value P 2max , and so on to T N Time P N Reach the maximum value P Nmax , where T1-T N When the power control module is used to share and allocate the transmission power of N radiating surfaces, the sum of the maximum transmission power of different radiating surfaces at different times is greater than the maximum transmission power of the multi-surface antenna system, that is, P 1max +P 2max +…+P Nmax >P total , and at different times, the maximum transmission power of different radiating surfaces is less than or equal to the maximum transmission power of the multi-surface antenna system, that is, P 1max ≤P total , P 2max ≤P total ,…,P Nmax ≤P total , and at the same time, the sum of the transmission powers of different radiating surfaces is less than the maximum transmission power of the multi-surface antenna system, that is, P1+P2+…+P N ≤P total .

[0080] It should be understood that in order to make P 1max +P2max +…+P Nmax >P total , it is necessary to improve the power amplification capacity of the power amplifier module in the RF channel, so it is necessary to improve the design specifications of the power amplifier module, that is, to improve the maximum power amplification capacity of the power amplifier 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 amplifier 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 amplifier capacity, thereby improving the performance of the multi-faceted antenna system.

[0081] Specifically, for the N radiating surfaces in the multi-surface 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-surface antenna system is greater than the maximum transmission power (P total ) divided by the total number of RF channels in the multi-surface antenna system.

[0082] For ease of understanding, the following Figure 5 , an exemplary description is given of the specific power sharing allocation scheme of the power control module 530.

[0083] Exemplarily, the maximum transmission power of the standard specification of the two-sided antenna system 500 is 200W. The radiation surface 510 corresponds to the RF channel 512, and the RF channel 512 includes a power amplifier module 513. The radiation 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 amplifier 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 (2) of the two-sided antenna system 500. For example, the power amplifier capacity of the power amplifier module 513 is greater than 100W; for another example, the power amplifier capacity of the power amplifier module 523 is greater than 100W; for another example, the power amplifier capacity of the power amplifier module 513 and the power amplifier module 523 are both greater than 100W.

[0084] The following description is made by taking the example that the available transmission power value of the two-sided antenna system 500 is 200 W, and the maximum transmission power of each radiating surface is also 200 W, that is, the maximum transmission power of the radiating surface 510 and the radiating surface 520 are both 200 W.

[0085] 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.

[0086] For example, at time T2, users in area 2 have communication services, and the transmission power required by the services is 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.

[0087] For example, at time T3, users in area 1 and users in area 2 both have communication services, and the transmission powers required by the services of users in area 1 and users in area 2 are both 100W. At this time, power control module 530 controls the transmission powers of radiation surface 510 and radiation surface 520 to be 100W respectively.

[0088] For example, at time T4, both users in area 1 and users in area 2 have communication services, and the transmission powers corresponding to the service requirements of users in area 1 and users in area 2 are 80W and 50W respectively. The power control module 530 allocates 80W to the radiation surface 510 and 50W to the radiation surface 520 according to the service requirements. At this time, there is still 70W of unallocated or remaining 70W in the available transmission power value of the two-sided antenna system 500 (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 two-sided antenna system is 70W). In order 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 radiation surface 510 and the radiation surface 520 respectively in a ratio of 1:1, that is, the actual power control module 530 controls the radiation surface 510 to transmit 115W, and controls the radiation surface 520 to transmit 85W.

[0089] It should be noted that the above Figure 5 In the example, 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.

[0090] 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.

[0091] Based on the above power allocation scheme, at a certain moment, the total transmission power of each radiation surface of the system does not exceed the nominal maximum transmission power of the system; but at different moments, the sum of the maximum transmission power of different radiation surfaces exceeds the nominal maximum transmission power of the system. This realizes the cooperation and power sharing allocation between multiple radiation surfaces. When different radiation surfaces serve different cells, power sharing between cells can be realized.

[0092] Figure 6A schematic structural diagram of a three-sided antenna system 600 of the present application is shown.

[0093] like Figure 6 As shown, the three-surface antenna system 600 includes a radiating surface 610, a radiating surface 620, and a radiating surface 630, each radiating surface serving users in a respective area, for example Figure 6 In the example, the radiation surface 610 serves users in area 1, the radiation surface 620 serves users in area 2, and the radiation surface 630 serves users in area 3. Each radiation surface includes at least one antenna unit, and the orientations of different radiation surfaces are not all the same (or, among the three radiation surfaces of the three-surface antenna system 600, at least two radiation surfaces have different orientations), for example Figure 6 The middle radiating surface 610 includes an antenna 611 and an antenna 612, the radiating surface 620 includes an antenna 621, and the radiating surface 630 includes an antenna 631. The radiating surface 610 and the radiating surface 620 have different directions, and the radiating surface 610 and the radiating surface 630 have different directions. The radiating surface 620 and the radiating surface 630 have the same direction. The antenna of each radiating surface is connected to the RF channel at the back end, and the RF channel includes a power amplifier module (PA), such as Figure 6 In the figure, 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, antenna 631 is connected to RF channel 632, and RF channel 632 includes a power amplifier module 633.

[0094] It should be understood that the directions of different radiating surfaces are not all the same, and it is sufficient that at least two radiating surfaces included in the multi-surface antenna system have different directions. Figure 6 In addition to the fact that the radiation surface 610 and the radiation surface 620 are oriented differently, the radiation surface 610 and the radiation surface 630 are oriented differently, and the radiation surface 620 and the radiation surface 630 are oriented the same, in a possible implementation manner, the radiation surface 610, the radiation surface 620, and the radiation surface 630 may also be oriented differently, and the present application is not limited to this.

[0095] It should be noted that the radio frequency channel and the antenna may be 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)).

[0096] exist Figure 6The three-sided antenna system 600 shown further includes a power control module 630, which is logically connected to the RF channel 613, the RF channel 622, and the RF channel 632. Specifically, the power control module 630 is used to allocate power to different radiating surfaces in the three-sided antenna system 600 according to business requirements.

[0097] 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. The present application does not limit the connection method of the logical connection.

[0098] 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 is not limited to this.

[0099] It should be noted that the relevant description of the power control module 630 can be found in Figure 5 The related description of the medium power control module 530 is omitted here to avoid redundancy.

[0100] For ease of understanding, the specific power allocation scheme of the power control module 630 is exemplarily described below.

[0101] Exemplarily, the nominal maximum transmission power of the three-sided antenna system 600 is 300W. The radiation surface 610 corresponds to the RF channel 613, and the RF channel 613 includes a power amplifier module 614; the radiation surface 620 corresponds to the RF channel 622, and the RF channel 622 includes a power amplifier module 623; the radiation surface 630 corresponds to the RF channel 632, and the RF channel 632 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 amplifier module 614 is greater than 200 W; for another example, the power amplification capacity of the power amplifier module 623 is greater than 200 W; for another example, the power amplification capacity of the power amplifier module 633 is greater than 200 W; for another example, the power amplification capacity of the power amplifier module 614 and the power amplifier module 623 are both greater than 200 W; for another example, the power amplification capacity of the power amplifier module 614, the power amplifier module 623 and the power amplifier module 633 are all greater than 200 W, and so on.

[0102] The following description is made by taking the example that the available transmission power value of the three-surface antenna system 600 is 300 W, and the independent maximum transmission power of each radiation surface is also 300 W, that is, the maximum transmission power of the radiation surface 610, the radiation surface 620, and the radiation surface 630 are all 300 W.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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 100 W and 50 W respectively. Users in area 3 have no communication services. At this time, the power control module 630 allocates 100 W to the radiation surface 510 and 50 W to the radiation surface 520 according to the service requirements. At this time, there is still 150 W of unallocated or remaining 150 W 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 150 W). 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 power of 150W, controls the radiation surface 620 to transmit power of 100W, and controls the radiation surface 630 to transmit power of 50W.

[0108] It should be noted that the above Figure 6 In the example, 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.

[0109] Based on the above power allocation scheme, at a certain moment, the total transmission power of each radiation surface of the system does not exceed the nominal maximum transmission power of the system; but at different moments, the sum of the maximum transmission power of different radiation surfaces exceeds the nominal maximum transmission power of the system. This realizes the cooperation and power sharing allocation between multiple radiation surfaces. When different radiation surfaces serve different cells, power sharing between cells can be realized.

[0110] It should be understood that the above Figure 5 and Figure 6 The multi-faceted antenna system shown may be a base station, or other communication equipment having the same or similar functions as a base station, etc., and this application is not limited to this.
