Description

A power distribution method and apparatus

[0001] This application claims priority to Chinese Patent Application No. 202410956838.1, filed on July 16, 2024, entitled "A Power Distribution Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a power distribution method and apparatus. Background Technology

[0003] When deploying a wireless communication site, the maximum mains power or maximum distribution power required for the entire wireless communication site is usually calculated based on the transmit power of each radio frequency device in the site under maximum load. Power is then supplied to the wireless communication site according to this maximum mains power or maximum distribution power to ensure the overall power supply satisfaction of the wireless communication site.

[0004] However, when the mains power distribution power is less than the mains power distribution power required by the entire wireless communication site, how to balance the power supply needs of each radio frequency device in the wireless communication site becomes an urgent problem to be solved. Summary of the Invention

[0005] This application provides a power distribution method and apparatus that solves the problem of how to balance the power supply requirements of each radio frequency device in a wireless communication site when the mains power distribution power is less than the mains power distribution power required by the entire wireless communication site.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] A first aspect of this application provides a power allocation method applied to a wireless communication site, the wireless communication site including multiple radio frequency (RF) devices. The method includes: first, acquiring power demand information of the multiple RF devices; then, determining power allocation information for each RF device based on the power demand information of the multiple RF devices and the mains power distribution information of the wireless communication site, the power allocation information indicating the allocated power for the corresponding RF device, wherein the sum of the power demands of the multiple RF devices is greater than the mains power distribution, and at least one RF device has an allocated power less than its power demand; finally, sending the corresponding power allocation information to each of the multiple RF devices.

[0008] Based on this scheme, firstly, the power requirement information of multiple radio frequency (RF) devices is obtained. Then, based on the power requirement information of the multiple RF devices and the mains power distribution information of the wireless communication site, the power allocation information for each RF device is determined. This power allocation information indicates the allocated power for the corresponding RF device. The sum of the power requirements of multiple RF devices is greater than the mains power distribution power, and at least one RF device has an allocated power less than its required power. Finally, the corresponding power allocation information is sent to each of the multiple RF devices. Therefore, when the mains power distribution power is less than the total mains power distribution power required by the entire wireless communication site, the power supply requirements of each RF device in the wireless communication site can be balanced, without requiring upgrades or modifications to the power supply system of the wireless communication site. This reduces implementation costs and shortens the implementation cycle.

[0009] In conjunction with the first aspect, in one possible implementation, determining the power allocation information for each radio frequency (RF) device based on the power demand information of multiple RF devices and the mains power distribution information of the wireless communication site includes: determining the power allocation information for each RF device according to a power allocation strategy based on the power demand information of multiple RF devices and the mains power distribution information. The power allocation strategy includes: allocating power according to the priority of the multiple RF devices, or allocating power according to the ratio of the power demand of each RF device to the sum of the power demands of all RF devices.

[0010] Based on this scheme, the power allocation information of each radio frequency (RF) device is determined according to the power demand information and mains power distribution information of each RF device, and the power allocation strategy is followed. This allows for the balance of power supply requirements of each RF device in the wireless communication site when the mains power distribution is less than the required mains power distribution for the site. Furthermore, by determining the power allocation information of each RF device according to the power allocation strategy, the power demand of the RF devices in the wireless communication site can be met more flexibly, thereby reducing the operating cost of the wireless communication site.

[0011] In conjunction with the first aspect, in one possible implementation, the multiple radio frequency devices include radio frequency devices with different power consumption priorities, wherein the power supply satisfaction of the radio frequency device with higher power consumption priority is greater than or equal to the power supply satisfaction of the radio frequency device with lower power consumption priority, and the power supply satisfaction is the ratio of the allocated power to the required power of the radio frequency device.

[0012] Based on this scheme, the power allocation information of each radio frequency device is determined according to the energy consumption priority of multiple radio frequency devices, and the power requirements of low-power radio frequency devices are given priority. This allows for more flexible fulfillment of the power requirements of radio frequency devices in a wireless communication site, thereby reducing the overall energy consumption of the wireless communication site and lowering its operating costs.

[0013] In conjunction with the first aspect, in one possible implementation, the ratio of the allocated power of each of the multiple radio frequency devices to the sum of the allocated power of the multiple radio frequency devices is the same as the ratio of the power demand of each of the multiple radio frequency devices to the sum of the power demands of the multiple radio frequency devices.

[0014] Based on this scheme, the power allocation information of each radio frequency device is determined according to the proportion of the power demand of each radio frequency device to the sum of the power demands of multiple radio frequency devices, which can more flexibly meet the power demand of radio frequency devices in wireless communication sites.

[0015] In conjunction with the first aspect, in one possible implementation, the multiple radio frequency devices include radio frequency devices of different standards, wherein the power supply satisfaction of the radio frequency device with higher standard priority is greater than or equal to the power supply satisfaction of the radio frequency device with lower standard priority.

[0016] Based on this scheme, the power allocation information of each radio frequency device is determined according to the standard priority of each radio frequency device, and the power requirements of radio frequency devices with high standard priority are given priority, so as to more flexibly meet the power requirements of radio frequency devices in wireless communication sites.

[0017] In conjunction with the first aspect, in one possible implementation, the multiple radio frequency (RF) devices include multiple groups of RF devices, each group of RF devices including at least one RF device; based on the power demand information of the multiple RF devices and the mains power distribution information of the wireless communication site, the power allocation information of each RF device is determined, including: based on the group power demand information of each group of RF devices and the mains power distribution information of the wireless communication site, determining the group power allocation information of each group of RF devices, the group power allocation information being used to indicate the allocated power of the corresponding group of RF devices; and based on the group power allocation information of each group of RF devices and the power demand information of each RF device in the corresponding group of RF devices, determining the power allocation information of each RF device in each group of RF devices.

[0018] In conjunction with the first aspect, in one possible implementation, the above-mentioned acquisition of power requirement information of multiple radio frequency devices includes: firstly acquiring the power requirement information of each radio frequency device in each group of radio frequency devices, and then acquiring the group power requirement information of each group of radio frequency devices in the multiple radio frequency devices.

[0019] A second aspect of this application provides a power allocation device applied to a wireless communication site. This power allocation device communicates with multiple radio frequency (RF) devices within the wireless communication site. The power allocation device includes a transceiver module and a processing module. The transceiver module acquires power demand information from the multiple RF devices. The processing module determines power allocation information for each RF device based on the power demand information of the multiple RF devices and the mains power distribution information of the wireless communication site. The power allocation information indicates the allocated power for the corresponding RF device. The sum of the power demands of the multiple RF devices is greater than the mains power distribution, and at least one RF device has an allocated power less than its power demand. The transceiver module also transmits its corresponding power allocation information to each of the multiple RF devices.

[0020] In conjunction with the second aspect, in one possible implementation, the processing module is specifically used to determine the power allocation information for each radio frequency (RF) device according to a power allocation strategy, based on the power demand information of multiple RF devices and the mains power distribution information. The power allocation strategy includes: allocating power according to the priority of the multiple RF devices, or allocating power according to the ratio of the power demand of each RF device to the sum of the power demands of all RF devices.

[0021] In conjunction with the second aspect, in one possible implementation, the multiple radio frequency devices include radio frequency devices with different power consumption priorities, wherein the power supply satisfaction of the radio frequency device with higher power consumption priority is greater than or equal to the power supply satisfaction of the radio frequency device with lower power consumption priority, and the power supply satisfaction is the ratio of the allocated power to the required power of the radio frequency device.

[0022] In conjunction with the second aspect, in one possible implementation, the ratio of the allocated power of each of the multiple radio frequency devices to the sum of the allocated power of the multiple radio frequency devices is the same as the ratio of the power demand of each of the multiple radio frequency devices to the sum of the power demands of the multiple radio frequency devices.

[0023] In conjunction with the second aspect, in one possible implementation, multiple radio frequency devices include radio frequency devices of different standards, wherein the power supply satisfaction of the radio frequency device with higher standard priority is greater than or equal to the power supply satisfaction of the radio frequency device with lower standard priority.

[0024] In conjunction with the second aspect, in one possible implementation, the multiple radio frequency (RF) devices include multiple groups of RF devices, each group including at least one RF device. Specifically, the processing module is used to determine the group power allocation information for each group of RF devices based on the group power requirement information of each group and the mains power distribution information of the wireless communication site. This group power allocation information is used to indicate the allocated power for the corresponding group of RF devices. The processing module is also used to determine the power allocation information for each RF device within each group based on the group power allocation information and the power requirement information of each RF device within the corresponding group.

[0025] In conjunction with the second aspect, in one possible implementation, the transceiver module is also used to first obtain the power requirement information of each radio frequency device in each group of radio frequency devices, and then obtain the group power requirement information of each group of radio frequency devices in multiple radio frequency devices.

[0026] A third aspect of this application provides a computer-readable storage medium storing a computer program that, when run on a device, causes the device to perform the power distribution method described in the first aspect or any possible implementation thereof.

[0036] The following sections will discuss the fabrication and use of various embodiments in detail. However, it should be understood that many applicable inventive concepts provided in this application can be implemented in a variety of specific environments. The specific embodiments discussed are merely illustrative of specific ways of implementing and using this description and technology, and do not limit the scope of this application.

[0037] Unless otherwise defined, all technical terms used herein have the same meaning as commonly known to one of ordinary skill in the art.

[0038] Each circuit or other component may be described or referred to as "for" performing one or more tasks. In this context, "for" is used to imply a structure by indicating that the circuit / component includes a structure (e.g., a circuit system) that performs one or more tasks during operation. Therefore, even when the specified circuit / component is currently inoperable (e.g., not turned on), it can still be referred to as "for performing that task." Circuits / components used with the term "for" include hardware, such as circuits that perform operations.

[0039] The technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings. In this application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c can be single or multiple. In addition, in the embodiments of this application, the words "first," "second," etc., do not limit the quantity or order.

[0040] In this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0041] Before introducing the embodiments of this application, the background technology involved in this application will be introduced first.

[0042] When the mains power distribution capacity is less than the mains power distribution capacity required by the entire wireless communication site—for example, when the mains power distribution capacity is insufficient, resulting in the mains power distribution capacity being less than the mains power distribution capacity required by the entire wireless communication site, or when new radio frequency (RF) equipment is added to the wireless communication site, resulting in the mains power distribution capacity being less than the mains power distribution capacity required by the entire wireless communication site, making it impossible to add new RF equipment—how to balance the power supply needs of each RF device in the wireless communication site becomes an urgent problem to be solved.

[0043] In one possible embodiment, when the mains power distribution power is less than the maximum power required by the entire wireless communication site, the estimated power required by the wireless communication site can be estimated based on the historical traffic data volume of the site, and new radio frequency (RF) equipment can be deployed based on this estimated power and the mains power distribution power. For example, the estimated power required by the wireless communication site can be estimated based on the historical traffic data volume, and when it is determined, based on this estimated power and the mains power distribution power, that the power required to provide a 5G active antenna unit (AAU) can be deployed. However, when a sudden surge in traffic causes a power spike in the RF equipment at the wireless communication site, the site may trip, resulting in lower reliability.

[0044] In one possible embodiment, the power supply system of the wireless communication site can be upgraded by using a more stable alternating current (AC) mains power or by adding a battery pack, so that when the power supply system of the wireless communication site supplies power to the wireless communication site, it can ensure the overall power supply satisfaction of the wireless communication site.

[0045] For example, Figure 1(a) shows a curve of the real-time power of a wireless communication station over time. When the real-time power of the wireless communication station is less than the mains power, the wireless communication station can operate normally. When the real-time power of the wireless communication station is greater than the mains power, the wireless communication station will trip. Figure 1(b) shows a curve of the real-time power of another wireless communication station over time. Compared with Figure 1(a), the difference is that the power supply system of the wireless communication station is upgraded by adding a battery pack. When the real-time power of the wireless communication station is greater than the mains power, as shown in Figure 1(b), the battery pack provides power to the wireless communication station to supplement the portion of the real-time power exceeding the mains power, thereby ensuring the overall power supply satisfaction of the wireless communication station.

[0046] However, upgrading the power supply system of wireless communication sites takes a long time, approximately 4 to 12 weeks, and requires additional equipment, which will result in higher costs.

[0047] In one possible embodiment, considering the characteristics of new radio (NR) services that momentarily occupy full bandwidth and momentarily idle, dynamic power sharing technology between NR carriers can be used to achieve power sharing among multiple NR carriers sharing the same power amplifier (PA) in the same radio frequency device. This allows carriers that occupy full bandwidth but still have data to be scheduled to momentarily use the power of idle carriers, thus overcoming the limitations of static power configuration of radio frequency devices.

[0048] For example, as shown in Figure 2(a), a resource block (RB) diagram of a radio frequency (RF) device is presented. This RF device includes carrier 1 and carrier 2, and each carrier includes resource blocks RB1 to RBn, where n is a positive integer. Taking a scenario where carrier 1 is idle, carrier 2 is fully operational, each resource block in carrier 2 is allocated a power of 1, and the user data volume is 2n, the amount of data that carrier 2 can transmit can be expressed as: n × 1 (number of resource blocks × power allocated to each resource block) = n. It is understood that user data volume n cannot be transmitted through carrier 2. As shown in Figure 2(b), by employing NR carrier dynamic power sharing technology, the power of carrier 1 is shared with carrier 2. At this time, each resource block in carrier 2 is allocated a power of 2, and the amount of data that carrier 2 can transmit can be expressed as: n × 2 (number of resource blocks × power allocated to each resource block) = 2n. It is understood that the user data volume 2n can be transmitted through carrier 2.

[0049] However, NR carrier dynamic power sharing technology cannot achieve power sharing between different radio frequency (RF) devices. For example, when one RF device is idle and another RF device requires full service power, power sharing between the two RF devices cannot be achieved through NR carrier dynamic power sharing technology. Furthermore, this NR carrier dynamic power sharing technology can achieve power sharing among multiple NR carriers sharing the same power amplifier within the same RF device when the mains power distribution power is greater than or equal to the maximum power distribution power required by the entire wireless communication site. When the mains power distribution power is less than the mains power distribution power required by the entire wireless communication site, this NR carrier dynamic power sharing technology is ineffective.

[0050] In summary, when the mains power distribution power is less than the mains power distribution power required by the entire wireless communication site, there are problems such as poor reliability, long transformation cycle, high cost, and inapplicability of NR carrier dynamic power sharing technology when balancing the power supply needs of each radio frequency device in the wireless communication site.

[0051] Based on this, the embodiments of this application provide a power allocation method, which allocates the power of each radio frequency device according to the mains power distribution power of the wireless communication site and the power demand of each radio frequency device in the wireless communication site, so as to balance the power supply demand of each radio frequency device in the wireless communication site when the mains power distribution power is less than the mains power distribution power required by the entire wireless communication site.

[0052] The power distribution method provided in this application embodiment can be applied to the wireless communication station 300 shown in FIG. 3. The wireless communication station 300 includes a power supply cabinet 310, a tower 320, and multiple radio frequency devices 330 installed on the tower 320. These multiple radio frequency devices 330 can also be referred to as radio frequency modules or radio frequency units. This application embodiment does not limit the specific number of radio frequency devices included in the multiple radio frequency devices 330. The power supply cabinet 310 is used to obtain mains power and perform power conversion on the mains power to provide power to the multiple radio frequency devices 330.

[0053] In one possible embodiment, the plurality of radio frequency devices 330 may include an AAU, a building base band unit (BBU), or a remote radio unit (RRU), and this application embodiment does not limit this to any particular type.

[0054] In one possible embodiment, the plurality of radio frequency devices 330 may be of 3G, 4G, 5G, or other future standards, which are not limited in this application embodiment.

[0055] In one possible embodiment, the plurality of radio frequency devices 330 may include radio frequency devices of the same standard, or may include radio frequency devices of different standards. This application embodiment does not limit this.

[0056] In one possible embodiment, when the plurality of radio frequency devices 330 include a plurality of radio frequency devices of the same standard, the frequency bands of the plurality of radio frequency devices of the same standard are different, or the frequency bands of the plurality of radio frequency devices of the same standard are the same. This application embodiment does not limit this.

[0057] For example, referring to FIG3, the plurality of radio frequency devices 330 may include 5G AAU 4.9 GHz, 5G AAU 2.6 GHz, 4G RRU 2.1 GHz and 4G RRU 1.8 GHz. In the following embodiments of this application, the plurality of radio frequency devices 330 including 5G AAU 4.9 GHz, 5G AAU 2.6 GHz, 4G RRU 2.1 GHz and 4G RRU 1.8 GHz are used as examples for exemplary description.

[0058] In one possible embodiment, the plurality of radio frequency devices 330 may include multiple groups of radio frequency devices, and each group of radio frequency devices may include at least one radio frequency device. When a group of radio frequency devices includes multiple radio frequency devices, the multiple radio frequency devices may be of the same or different standards, or the multiple radio frequency devices may be of the same or different frequency bands. This application embodiment does not limit this.

[0059] For example, referring to FIG3, the plurality of radio frequency devices 330 may include a first group of radio frequency devices 340 and a second group of radio frequency devices 350. Each radio frequency device in the first group of radio frequency devices 340 has the same standard but different frequency bands, and each radio frequency device in the second group of radio frequency devices 350 has the same standard but different frequency bands. Specifically, the first group of radio frequency devices 340 may include 5G AAU 4.9GHz and 5G AAU 2.6GHz, and the second group of radio frequency devices 350 may include 4G RRU 2.1GHz and 4G RRU 1.8GHz. In the following embodiments of this application, the plurality of radio frequency devices 330 include the first group of radio frequency devices 340 and the second group of radio frequency devices 350, the first group of radio frequency devices 340 includes 5G AAU 4.9GHz and 5G AAU 2.6GHz, and the second group of radio frequency devices 350 includes 4G RRU 2.1GHz and 4G RRU 1.8GHz as an example for illustrative purposes.

[0060] Figure 4(a) shows a power distribution logic diagram of a wireless communication station 300. The power system 311 in the power cabinet 310 is used to provide power to multiple radio frequency devices 330. Figure 4(b) shows another power distribution logic diagram of a wireless communication station 300. The power system 311 in the wireless communication station 300 includes a power module 3111. For example, the power module 3111 can be a power supply unit (PSU). When using the power distribution method provided in the embodiments of this application, the power distribution module 3112 can be deployed in the power module 3111 through software version upgrade, or the power distribution module 3112 can be deployed on the baseband board of any one of the multiple radio frequency devices 330 through software version upgrade. The power distribution module 3112 communicates with each of the multiple radio frequency devices 330. The power distribution module 3112 can also be called a mains power collaborative distribution module. The following embodiments of this application use the deployment of the power distribution module 3112 in the power module 3111 as an example for illustrative purposes.

[0061] The power allocation module 3112 is used to execute the power allocation method provided in the embodiments of this application, and to balance the power supply requirements of each radio frequency device in the wireless communication station 300 when the mains power distribution power is less than the mains power distribution power required by the entire wireless communication station 300.

[0062] In one possible embodiment, as shown in Figure 4(c), when multiple radio frequency devices 330 include a first group of radio frequency devices 340 and a second group of radio frequency devices 350, wherein the first group of radio frequency devices 340 includes 5G AAU 4.9GHz and 5G AAU 2.6GHz, and the second group of radio frequency devices 350 includes 4G RRU 2.1GHz and 4G RRU 1.8GHz, when using the power allocation method provided in this application embodiment, a first group of power allocation modules 360 can be deployed on the baseband board of one radio frequency device (e.g., 5G AAU 4.9GHz) in the first group of radio frequency devices 340, and a second group of power allocation modules 370 can be deployed on the baseband board of one radio frequency device (e.g., 4G RRU 2.1GHz) in the second group of radio frequency devices, in order to facilitate understanding of the power allocation logic, the first group of power allocation modules 360 and the second group of power allocation modules 370 are placed outside the radio frequency devices in Figure 4(c).

[0063] The first power distribution module 360 ​​and the second power distribution module 370 are used to execute the power distribution method provided in the embodiments of this application, and to balance the power supply requirements of each radio frequency device in the wireless communication site 300 when the mains power distribution power is less than the mains power distribution power required by the entire wireless communication site 300.

[0064] In one possible embodiment, taking the first group of radio frequency devices 340 as an example, the radio frequency device with the smallest PCI can be selected according to the physical cell identifier (PCI) of each radio frequency device in the first group of radio frequency devices 340, and the first group of power distribution modules 360 can be deployed on the baseband board of the radio frequency device. Alternatively, a radio frequency device can be randomly selected from the first group of radio frequency devices 340, and the first group of power distribution modules 360 can be deployed on the baseband board of the radio frequency device. This application embodiment does not limit this.

[0065] In one possible embodiment, as shown in FIG4(c), when using the power allocation method provided in the embodiments of this application, the power configuration module 3113 can be deployed in the power system 311 by means of software version upgrade. The power configuration module 3113 is used to obtain the mains power distribution information of the wireless communication station 300 and send the mains power distribution information to the power allocation module 3112. Thus, the power allocation module 3112 can balance the power supply demand of each radio frequency device in the wireless communication station 300 according to the mains power distribution information and the power demand of each radio frequency device in the wireless communication station 300 when the mains power distribution is less than the mains power distribution required by the entire wireless communication station 300.

[0066] Figure 5 shows a flowchart of a power allocation method provided in an embodiment of this application. This power allocation method is applied to the aforementioned wireless communication station 300 and includes steps S501-S503.

[0067] S501, the power distribution module 3112 obtains the power demand information of multiple radio frequency devices 330.

[0068] In one possible embodiment, each of the multiple radio frequency (RF) devices 330 can determine its power requirement information based on the expected data volume (also known as the expected traffic volume) and send this power requirement information to the power allocation module 3112. Thus, the power allocation module 3112 can obtain the power requirement information of each of the multiple RF devices 330. The power requirement information of each RF device can be used to indicate the required power of that RF device. The specific process by which each RF device determines its power requirement information can be found in existing technologies, and will not be elaborated upon here.

[0069] For example, referring to Figure 3, taking multiple radio frequency devices 330 including 5G AAU 4.9GHz, 5G AAU 2.6GHz, 4G RRU 2.1GHz and 4G RRU 1.8GHz as an example, the power allocation module 3112 can obtain the power requirement information of 5G AAU 4.9GHz (5 kilowatts, KW), 5G AAU 2.6GHz (5KW), 4G RRU 2.1GHz (4KW), and 4G RRU 1.8GHz (4KW).

[0070] S502, the power allocation module 3112 determines the power allocation information of each radio frequency device based on the power demand information of multiple radio frequency devices 330 and the mains power distribution information of the wireless communication station 300. The power allocation information is used to indicate the allocated power of the corresponding radio frequency device. The sum of the power demands of multiple radio frequency devices 330 is greater than the mains power distribution power. Among the multiple radio frequency devices 330, at least one radio frequency device has an allocated power that is less than the demand power of at least one radio frequency device.

[0071] Referring to Figure 3, the mains power distribution information is used to indicate the mains power distribution power that the power cabinet 310 can provide to the multiple radio frequency devices 330 after performing power conversion on the mains power.

[0072] In one possible embodiment, the sum of the distributed power of the plurality of radio frequency devices 330 is less than or equal to the mains power of the wireless communication station 300. This application embodiment does not limit this, but takes the example that the sum of the distributed power of the plurality of radio frequency devices 330 is equal to the mains power of the wireless communication station 300 for exemplary illustration.

[0073] For example, taking the mains power distribution information indicating a mains power distribution power of 15KW as an example, the power allocation module 3112 can determine the power allocation information for 5G AAU 4.9GHz as 5KW, 5G AAU 2.6GHz as 5KW, 4G RRU 2.1GHz as 2.5KW, and 4G RRU 1.8GHz as 2.5KW based on the power demand information of multiple radio frequency devices 330 and the mains power distribution power of 15KW. Taking 5G AAU 4.9GHz as an example, the power allocation information for 5G AAU 4.9GHz is used to indicate that the power allocated to 5G AAU 4.9GHz is 5KW. Understandably, the sum of the power requirements of the multiple radio frequency devices 330, 18KW (5KW+5KW+4KW+4KW), is greater than the mains power distribution power of 15KW. The power supply requirements of 5G AAU 4.9GHz and 5G AAU 2.6GHz are met. The power allocation of 4G RRU 2.1GHz, 2.5KW, is less than the power requirement of 4G RRU 2.1GHz, 4KW. The power allocation of 4G RRU 1.8GHz, 2.5KW, is less than the power requirement of 4G RRU 1.8GHz, 4KW. Thus, when the mains power distribution power is less than the mains power distribution power required by the wireless communication site 300, the power supply requirements of each radio frequency device in the wireless communication site 300 can be balanced.

[0074] In one possible embodiment, the power allocation module 3112 determines the power allocation information for each radio frequency (RF) device based on the power demand information of the multiple RF devices 330 and the mains power distribution information of the wireless communication station 300. This includes: the power allocation module 3112 determines the power allocation information for each RF device according to a power allocation strategy based on the power demand information of the multiple RF devices 330 and the mains power distribution information. The power allocation strategy includes: allocating power according to the priority of the multiple RF devices 330, or allocating power according to the ratio of the power demand of each RF device to the sum of the power demands of the multiple RF devices 330. Therefore, when the mains power distribution is less than the mains power distribution required by the wireless communication station 300, the power supply demand of each RF device in the wireless communication station 300 can be balanced. Furthermore, by determining the power allocation information for each RF device according to the power allocation strategy, the power demand of the RF devices in the wireless communication station 300 can be met more flexibly, reducing the operating cost of the wireless communication station 300.

[0075] Specifically, in a first possible embodiment, the multiple radio frequency devices 330 may include radio frequency devices with different energy consumption priorities. The power allocation module 3112 can determine the power allocation information of each radio frequency device according to the energy consumption priorities of the multiple radio frequency devices 330. Among them, the power supply satisfaction of the radio frequency device with higher energy consumption priority is greater than or equal to the power supply satisfaction of the radio frequency device with lower energy consumption priority, and the power supply satisfaction is the ratio of the allocated power to the required power of the radio frequency device.

[0076] The energy consumption priority of the aforementioned radio frequency (RF) devices is related to their energy consumption. The lower the energy consumption of an RF device, the higher its energy consumption priority; conversely, the higher the energy consumption of an RF device, the lower its energy consumption priority.

[0077] For example, taking the power consumption priority of 5G AAU 4.9GHz, 5G AAU 2.6GHz, 4G RRU 2.1GHz and 4G RRU 1.8GHz as decreasing sequentially, the power allocation module 3112 can determine the power allocation information of 5G AAU 4.9GHz as 5KW, 5G AAU 2.6GHz as 5KW, 4G RRU 2.1GHz as 4KW and 4G RRU 1.8GHz as 1KW according to the power consumption priority of the multiple radio frequency devices 330. The power supply satisfaction rates for 5G AAU 4.9GHz (5KW / 5KW), 5G AAU 2.6GHz (5KW / 5KW), and 4G RRU 2.1GHz (4KW / 4KW) are equal, all greater than the 25% power supply satisfaction rate (1KW / 4KW) of 4G RRU 1.8GHz. Understandably, the power allocation module 3112 determines the power allocation information for each radio frequency device 330 according to their energy consumption priorities, prioritizing the power needs of low-power radio frequency devices. This allows for more flexible fulfillment of the power requirements of radio frequency devices in the wireless communication site 300, reducing the overall energy consumption and operating costs of the wireless communication site 300.

[0078] In a second possible implementation, the power allocation module 3112 can determine the power allocation information for each radio frequency device according to the proportion of each radio frequency device's power requirement to the sum of the power requirements of the plurality of radio frequency devices 330. This ensures that the ratio of the allocated power of each radio frequency device to the sum of the allocated power of the plurality of radio frequency devices 330 is the same as the ratio of the power requirement of each radio frequency device to the sum of the power requirements of the plurality of radio frequency devices 330.

[0079] For example, the power allocation module 3112 can determine the power allocation information for the 5G AAU 4.9GHz as 4.17KW ((5KW / 18KW)×15KW), the 5G AAU 2.6GHz as 4.17KW ((5KW / 18KW)×15KW), the 4G RRU 2.1GHz as 3.33KW ((4KW / 18KW)×15KW), and the 4G RRU 1.8GHz as 3.33KW ((4KW / 18KW)×15KW), based on the proportion of each radio frequency device's power requirement to the sum of the power requirements of the multiple radio frequency devices 330. Understandably, by determining the power allocation information for each radio frequency device according to the proportion of each device's power requirement to the sum of the power requirements of the multiple radio frequency devices 330, the power allocation module 3112 can more flexibly meet the power requirements of the radio frequency devices in the wireless communication site.

[0080] In a third possible implementation, the multiple radio frequency devices 330 may include radio frequency devices of different standards, and the power allocation module 3112 can determine the power allocation information of each radio frequency device according to the standard priority of each radio frequency device. Specifically, the power supply satisfaction of a radio frequency device with a higher standard priority is greater than or equal to the power supply satisfaction of a radio frequency device with a lower standard priority.

[0081] In one possible embodiment, the above-mentioned standard priority can be preset, for example, it can be manually configured, and the priority of each standard can be set as needed.

[0082] For example, taking the standard priority of 5G AAU 4.9GHz and 5G AAU 2.6GHz as higher than that of 4G RRU 2.1GHz and 4G RRU 1.8GHz as an example, the power allocation module 3112 can determine the power allocation information of 5G AAU 4.9GHz as 5KW, 5G AAU 2.6GHz as 5KW, 4G RRU 2.1GHz as 2.5KW, and 4G RRU 1.8GHz as 2.5KW according to the standard priority of the multiple radio frequency devices 330. The power supply satisfaction rate for 5G AAU 4.9GHz is 100% (5KW / 5KW) or 5G AAU 2.6GHz is 100% (5KW / 5KW), while the power supply satisfaction rate for 4G RRU 2.1GHz is 62.5% (2.5KW / 4KW) or 4G RRU 1.8GHz is 62.5% (2.5KW / 4KW). Understandably, the power allocation module 3112 determines the power allocation information for each radio frequency device according to its standard priority, prioritizing the power requirements of radio frequency devices with higher standard priority, thereby more flexibly meeting the power needs of radio frequency devices in the wireless communication site 300.

[0083] In one possible embodiment, the multiple radio frequency devices 330 include multiple groups of radio frequency devices, each group of radio frequency devices including at least one radio frequency device. This application embodiment does not limit this. Referring to Figure 4(c), this application embodiment takes the multiple radio frequency devices 330 as including a first group of radio frequency devices 340 and a second group of radio frequency devices 350. The first group of radio frequency devices 340 includes 5G AAU 4.9GHz and 5G AAU 2.6GHz, and the second group of radio frequency devices 350 includes 4G RRU 2.1GHz and 4G RRU 1.8GHz. The first group of radio frequency devices 340 corresponds to the first group of power allocation modules 360, and the second group of radio frequency devices 350 corresponds to the second group of power allocation modules 370 as an example for illustrative purposes.

[0084] As shown in Figure 6, the power allocation module 3112 obtains power requirement information from multiple radio frequency devices 330, including:

[0085] First, the first power allocation module 360 ​​acquires the power demand information of 5KW for 5G AAU 4.9GHz and 5KW for 5G AAU 2.6GHz. Based on these two power demand information, it determines a first set of power demand information of 10KW (5KW+5KW) and sends this first set of power demand information to the power allocation module 3112. The second power allocation module 370 acquires the power demand information of 4KW for 4G RRU 2.1GHz and 4KW for 4G RRU 1.8GHz. Based on these two power demand information, it determines a second set of power demand information of 8KW (4KW+4KW) and sends this second set of power demand information to the power allocation module 3112. The group power requirement information for each group of RF devices can be used to indicate the power required by that group of RF devices.

[0086] The power allocation module 3112 obtains the first set of power demand information 10KW and the second set of power demand information 8KW, so as to obtain the power demand information 18KW for each of the multiple radio frequency devices 330.

[0087] Referring again to Figure 6, the power allocation module 3112 determines the power allocation information for each radio frequency device based on the power demand information of the multiple radio frequency devices 330 and the mains power distribution information of the wireless communication station 300, including:

[0088] First, the power allocation module 3112 determines the first power allocation information of the first group of radio frequency devices 340 (10KW), the second power requirement information of the second group of radio frequency devices 350 (8KW), and the mains power distribution information (15KW) of the wireless communication station 300, and sends the first power allocation information to the first power allocation module 360 ​​and the second power allocation information to the second power allocation module 370. The first power allocation information is used to indicate the allocated power of the first group of radio frequency devices 340, and the second power allocation information is used to indicate the allocated power of the second group of radio frequency devices 350.

[0089] In one possible embodiment, the power allocation module 3112 can determine the group power allocation information of each group of radio frequency devices in a manner similar to the power allocation strategy described above, according to the energy consumption priority of each group of radio frequency devices, or according to the proportion of the power demand of each group of radio frequency devices to the sum of the power demands of the multiple radio frequency devices 330, or according to the standard priority of each group of radio frequency devices. The specific process can be referred to the process of determining the power allocation information of each radio frequency device according to the power allocation strategy described above. The embodiments of this application will not be repeated here. The embodiments of this application take the example that the standard priority of the first group of radio frequency devices 340 is higher than the standard priority of the second group of radio frequency devices 350, and the power allocation module 3112 determines the group power allocation information of each group of radio frequency devices according to the standard priority of each group of radio frequency devices, for exemplary illustration.

[0090] For example, referring to Figure 6, the power allocation module 3112 can determine the first power allocation information of the first group of radio frequency devices 340 (10KW), the second power allocation information of the second group of radio frequency devices 350 (8KW), and the mains power distribution information of the wireless communication station 300 (15KW) based on the first power demand information of the first group of radio frequency devices 340 (10KW), the second power demand information of the second group of radio frequency devices 350 (8KW), and the mains power distribution information of the wireless communication station 300 (15KW).

[0091] Then, the first power allocation module 360 ​​can determine the power allocation information for 5G AAU 4.9GHz and 5G AAU 2.6GHz based on the first power allocation information of 10KW from the first group of RF devices 340, and the power requirements of 5KW for 5G AAU 4.9GHz and 5KW for 5G AAU 2.6GHz within the first group of RF devices 340. The second power allocation module 370 can determine the power allocation information for 4G RRU 2.1GHz and 4G RRU 1.8GHz based on the second power allocation information of 5KW from the second group of RF devices 350, and the power requirements of 4KW for 4G RRU 2.1GHz and 4G RRU 1.8GHz within the second group of RF devices 350. Thus, the power requirement information for each RF device in each group of RF devices is determined.

[0092] Understandably, when multiple radio frequency (RF) devices 330 include a first group of RF devices 340 and a second group of RF devices 350, the power allocation module 3112 first determines the group power allocation information for each group of RF devices based on the group power requirement information of each group of RF devices 300 and the mains power distribution information of the wireless communication station 300. Then, the first group power allocation module 360 ​​and the second group power allocation module 370 determine the power allocation information for each RF device in each group of RF devices based on the group power allocation information of each group of RF devices and the power requirement information of each RF device in the corresponding group of RF devices. This eliminates the need to complete all power allocation calculations at once, thereby reducing the computational load of the power allocation module 3112.

[0093] In one possible embodiment, the first group of power allocation modules 360 or the second group of power allocation modules 370 can determine the allocated power of each radio frequency device in the group according to a power allocation strategy similar to that described above, based on the energy consumption priority of the radio frequency devices in the group, or based on the proportion of the power demand of the radio frequency devices in the group to the total power demand of the entire radio frequency device group, or based on the standard priority of the radio frequency devices in the group. The specific process can be referred to the process of determining the power allocation information of each radio frequency device according to the power allocation strategy described above. The embodiments of this application will not be repeated here. The embodiments of this application take the example that the first group of power allocation modules 360 or the second group of power allocation modules 370 determine the allocated power of each radio frequency device in the group according to the proportion of the power demand of the radio frequency devices in the group to the total power demand of the entire radio frequency device group, and provide an exemplary description.

[0094] For example, referring to Figure 6, the first power allocation module 360 ​​can determine the power allocation information for 5G AAU 4.9GHz as 5KW ((5KW / 10KW)×10KW) and the power allocation information for 5G AAU 2.6GHz as 5KW ((5KW / 10KW)×10KW) according to the proportion of the power demand of the radio frequency devices in the group to the total power demand of the entire radio frequency equipment group. The second power allocation module 370 can determine the power allocation information for 4G RRU 2.1GHz as 2.5KW ((4KW / 8KW)×5KW) and the power allocation information for 4G RRU 1.8GHz as 2.5KW ((4KW / 8KW)×5KW) according to the proportion of the power demand of the radio frequency devices in the group to the total power demand of the entire radio frequency equipment group.

[0095] S503, the power distribution module 3112 sends the corresponding power distribution information to multiple radio frequency devices 330.

[0096] Each radio frequency device obtains its corresponding power allocation information, determines the number of resource blocks to call based on its corresponding power allocation information, and runs them. Thus, when the mains power distribution power is less than the mains power distribution power required by the entire wireless communication site 300, the power supply demand of each radio frequency device in the wireless communication site 300 can be balanced.

[0097] Specifically, when the mains power distribution power is insufficient, resulting in a power distribution power less than the total mains power distribution power required by the entire wireless communication site 300, or when new radio frequency (RF) devices are added to the wireless communication site 300, causing the mains power distribution power to be less than the total mains power distribution power required by the entire wireless communication site 300, the power supply needs of each RF device in the wireless communication site 300 can be balanced. Therefore, the wireless communication site 300 can add RF devices as needed, such as deploying a 5G AAU, without requiring upgrades or modifications to the power supply system of the wireless communication site 300, thus reducing implementation costs and shortening the implementation cycle.

[0098] In one possible embodiment, referring to FIG6, when the plurality of radio frequency devices 330 includes a first group of radio frequency devices 340 and a second group of radio frequency devices 350, the power allocation module 3112 sends corresponding power allocation information to the plurality of radio frequency devices 330, including:

[0099] First, the power distribution module 3112 sends a first set of power distribution information of 10KW to the first group of power distribution modules 360 and a second set of power distribution information of 5KW to the second group of power distribution modules 370.

[0100] Then, the first power allocation module 360 ​​sends power allocation information of 5KW to the 5G AAU 4.9GHz and 5KW to the 5G AAU 2.6GHz. The second power allocation module 370 sends power allocation information of 2.5KW to the 4G RRU 2.1GHz and 2.5KW to the 4G RRU 1.8GHz.

[0101] In one possible embodiment, referring to FIG6, during period M-1, where M is a positive integer greater than or equal to 1, the first group power allocation module 360 ​​can obtain the first group power demand information of 10KW, and the second group power allocation module 370 can obtain the second group power demand information of 8KW, and send the group power demand information to the power allocation module 3112 respectively. The group power demand information of each group of radio frequency devices is used to indicate the power required by the group of radio frequency devices during period M+1.

[0102] During cycle M, power allocation module 3112 acquires the power demand information of each group of radio frequency devices, determines and sends a first group power allocation of 10KW to the first group power allocation module 360, and sends a second group power allocation of 5KW to the second group power allocation module 370. The first group power allocation module 360 ​​determines and sends a power allocation of 5KW to the 5G AAU 4.9GHz and 5G AAU 2.6GHz. The second group power allocation module 370 determines and sends a power allocation of 2.5KW to the 4G RRU 2.1GHz and 4G RRU 1.8GHz.

[0103] In cycle M+1, each of the multiple RF devices 330 determines the number of resource blocks to call and runs them based on the power allocation information. This allows the power requirements of the multiple RF devices 330 to be balanced in cycle M+1 according to their power demands.

[0104] The power allocation method provided in this application embodiment first involves a power allocation module 3112 acquiring power demand information from multiple radio frequency (RF) devices 330. Then, based on the power demand information of the multiple RF devices 330 and the mains power distribution information of the wireless communication station 300, the power allocation module 3112 determines the power allocation information for each RF device. This power allocation information indicates the allocated power for the corresponding RF device. The sum of the power demands of the multiple RF devices 330 is greater than the mains power distribution, and at least one RF device has an allocated power less than its required power. Finally, the power allocation module 3112 sends its corresponding power allocation information to each of the multiple RF devices 330. Therefore, when the mains power distribution is less than the total mains power required by the entire wireless communication station 300, the power supply demand of each RF device in the wireless communication station 300 can be balanced. Furthermore, it eliminates the need to upgrade or modify the power supply system of the wireless communication station 300, thereby reducing implementation costs and shortening the implementation cycle.

[0105] As shown in FIG7, this application embodiment also provides a power distribution device 700, which can be the power distribution module 3112, the first group of power distribution modules 360 or the second group of power distribution modules 370 described above. The power distribution device 700 is used to implement the power distribution method of any of the above embodiments.

[0106] The power distribution device 700 includes a transceiver module 701 and a processing module 702 coupled to each other. For example, the transceiver module 701 supports the power distribution device 700 in transmitting and receiving signals, or in communicating with other devices.

[0107] In one possible embodiment, the transceiver module 701 or the processing module 702 can be used to implement the functions of the power distribution module 3112, the first power distribution module 360 ​​or the second power distribution module 370 described above.

[0108] For example, the transceiver module 701 described above can be used to perform steps S501 and S503 in FIG. 5, and / or other processes of the technology described herein. The processing module 702 can be used to perform step 502 in FIG. 5, and / or other processes of the technology described herein.

[0109] All relevant content of each step involved in the above method embodiments can be referenced from the functional description of the corresponding functional module, and will not be repeated here.

[0110] For example, in hardware implementation, the functions of processing module 702 can be executed by a processor, and the functions of transceiver module 701 can be executed by a transceiver (transmitter / receiver) and / or communication interface. Processing module 702 can be embedded in or independent of the processor of power distribution device 700 in hardware form, or it can be stored in the memory of power distribution device 700 in software form, so that the processor can call and execute the operations corresponding to the above functional units.
