Description

[Technical Field]

[0001] This application is filed based on and claims priority to a Chinese patent application having application number 202111422859.8 and filing date November 26, 2021, the entire contents of which are hereby incorporated by reference into this application.

[0002] The present application relates to the field of communications, and in particular to an energy-saving control method and its device, storage medium, and program product. [Background technology]

[0003] A massive multiple input and multiple output (MAS) base station system typically includes a baseband unit (BBU), a MAS active antenna unit (AAU), and a corresponding base station network management system. Here, the AAU is a MAS device and is the mainstream product form for 5G New Radio (NR) networking. Compared to the conventional 4G Long Term Evolution (LTE) 8T8R (i.e., eight transmit links and eight receive links) remote radio unit (RRU) device, the AAU device consumes significantly more energy than the RRU device. Therefore, the energy consumption requirements of an AAU device station are also higher than those of an RRU device station. Furthermore, the bandwidth requirements of 5G NR devices are several times higher than those of LTE 4G devices. Meanwhile, high device energy consumption means high power consumption during device operation, higher electricity bills for station network operation, and higher actual operating costs for customers. Relatively high operating costs to a certain extent limit customers' willingness to build new AAU stations, further constraining the development of 5G NR networks and the telecommunications industry.

[0004] In related technologies, there are two commonly used AAU operation energy saving modes: an energy saving mode that switches off some channels in a timed manner and a channel unified coarse tuning energy saving mode. The former mode reduces the success rate of RRC (Radio Resource Control) connection establishment after channel off, increases the success rate of RRC connection re-establishment, reduces the wireless connection rate, increases the wireless interruption rate, increases the average delay of downlink RLC (Radio Link Control) SDU (Service Data Unit), increases the downlink block error rate of MAC (Media Access Control) layer, increases the retransmission rate of downlink hybrid automatic repeat technology, reduces the CQI (Channel Quality Indicator) good rate, reduces the spatial division rate, and reduces the downlink rate. Regarding the latter, it is possible to estimate the optimal power voltage of the power devices on each channel based on the power configuration, and perform unified adjustment of the power voltage to allow the power devices on each channel to operate at a relatively good operating voltage; it is also possible to detect in real time and determine slots (or symbols) that have no service at all, and for slots (or symbols) that have no service, to power off all channels within the slots (or symbols); however, in order to turn off a slot (or symbol), it is necessary to very accurately determine whether the service is unloaded at the current time, which places relatively high requirements on software, and since there is a trapping effect on the power devices, frequently turning on and off the power devices by slot (or symbol) will cause the switch delay to become unstable or exceed the switch delay requirement required by the protocol, leading to performance degradation; therefore, slot turning off will increase the service delay and create a poor user experience.

[0015] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application will be described in more detail in conjunction with the following figures and examples. The specific examples described herein are only used to interpret the present application and are not intended to limit the present application.

[0016] It should be noted that while a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed out of the order shown in the flowcharts. In the specification and claims and the description of the drawings above, plural (or plural) means two or more, and terms such as greater than, less than, exceed, etc. are understood to be exclusive of the number, and terms such as greater than or equal to, less than or equal to, within, etc. are understood to be inclusive of the number.

[0017] The embodiments of the present application provide an energy-saving control method, a device therefor, a storage medium, and a program product therefor. Antenna information is first acquired. If the antenna information includes antenna beamforming information, an energy-saving determination process is performed based on the antenna beamforming information and a preset energy-saving policy to obtain a first operation control command. Finally, the first operation control command can be used to implement energy-saving control for the AAU. That is, unlike the energy-saving modes of the related art that selectively turn off some channels and the channel-unified coarse tuning energy-saving mode, the solution of the embodiments of the present application can obtain a currently appropriate first operation control command based on the antenna beamforming information acquired by the energy-saving control device, allowing the AAU to perform energy-saving control based on the currently acquired antenna beamforming information. Therefore, the solution of the embodiments of the present application can optimize traditional energy-saving methods without adding new hardware, reduce energy consumption during device operation, and minimize impact on service experience.

[0018] In the following, examples of the present application are further described in conjunction with the drawings. As shown in Fig. 1, Fig. 1 is an architecture schematic diagram of a base station configured to perform an energy saving control method according to one embodiment of the present application. In the example of Fig. 1, the base station 100 includes a BBU 120, an AAU 110, and a network management system 130. Here, the BBU 120 is installed between the network management system 130 and the AAU 110, and the BBU 120 is communicatively connected to the network management system 130 and the AAU 110, respectively.

[0019] In one embodiment, the BBU 120 can receive network management control signaling sent by the network management system 130. Upon receiving the network management control signaling, the BBU 120 can send a downlink baseband signal to the AAU 110, so that the AAU 110 performs associated signal processing on the received downlink baseband signal and transmits the processed downlink baseband signal to the air interface. In addition, the AAU 110 can receive an uplink wireless signal of the air interface, process the uplink wireless signal, and upload the processed uplink wireless signal to the BBU 120.

[0020] The network management system 130 can configure the BBU 120 and the AAU 110 and can also manage and control service performance. The BBU 120 and the AAU 110 may be connected via an enhanced Common Public Radio Interface (eCPRI).

[0021] The Common Public Radio Interface (CPRI) is an important communication interface standard used between a radio equipment control center and radio equipment in a cellular wireless network, and is widely used in global mobile communication systems, third-generation wireless communication technologies, and LTE and 5G base station systems. The eCPRI protocol is an evolution of the CPRI protocol, and is a CPRI protocol over Ethernet. The eCPRI protocol is an interface protocol that establishes a data transmission channel between the BBU 120 and the AAU 110. The data on the channel includes control plane data, user plane data, and synchronization plane data.

[0022] Furthermore, the AAU 110 is a device that combines an RRU and an antenna, while the BBU 120 is generally a network interface unit and a baseband processing unit of the base station 100. The AAU 110 can communicate with the BBU 120 via a fiber channel and realizes the transmission of uplink and downlink baseband signals with the BBU 120.

[0023] As shown in Figure 2, Figure 2 is an architecture schematic diagram of an AAU according to one embodiment of the present application. In the example of Figure 2, the AAU 110 includes a baseband processing module 116, a main control module 111, a massive MIMO transceiver module 112, a massive MIMO antenna filtering module 113, a clock module 114, and a power supply module 115. Here, the main control module 111 is respectively connected to the massive MIMO transceiver module 112 and the baseband processing module 116, the massive MIMO antenna filtering module 113 is connected to the massive MIMO transceiver module 112, and the baseband processing module 116 is connected to the BBU 120.

[0024] The power supply module 115 is configured to provide power to each component within the AAU 110, and the clock module 114 is configured to provide a clock signal to each component within the AAU 110.

[0025] In one embodiment, the AAU 110 receives a downlink baseband signal output by the BBU 120, and uses its own modules, such as a digital intermediate frequency transceiver module, a multi-channel input / output radio frequency channel link module, and a large-scale array antenna module, to perform signal processing of the downlink signal, such as digital intermediate frequency processing, digital-to-analog conversion processing, frequency conversion processing, small signal processing, power amplification processing, and filtering processing, and then transmits the signal to the air interface via the large-scale array antenna module as a downlink radio signal. The AAU 110 uses its own large-scale array antenna module to receive an uplink radio signal from the air interface, and uses its own modules, such as a multi-channel input / output radio frequency channel link module and a digital intermediate frequency receiver module, to perform filtering, amplification, frequency conversion, and digital intermediate frequency reception of the uplink radio signal, and generates an uplink baseband signal for uploading to the BBU 120.

[0026] Based on the base station 100 shown in Figure 1, Figure 3 shows a structural schematic diagram of an AI (Artificial Intelligence) energy-saving device 200 according to one embodiment of the present application, which includes an energy-saving controller 210, a channel control circuit module 220, and a channel controllable link module 230. Here, the channel control circuit module 220 is communicatively connected to the energy-saving controller 210 and the channel controllable link module 230 respectively.

[0027] The energy-saving control device 210 is configured to acquire antenna information for each channel in the AAU. If the antenna information includes antenna beamforming information, the energy-saving control device 210 performs an energy-saving determination process based on the antenna beamforming information and a preset energy-saving policy to obtain a first operation control command and transmit the first operation control command to the channel control circuit module 220. If the antenna information includes power configuration information of the AAU, the energy-saving determination process is performed based on the power configuration information and a preset energy-saving policy to obtain a second operation control command and transmit the second operation control command to the channel control circuit module 220. Here, the antenna beamforming information may be antenna weight value information or other information, and is not specifically limited herein. For example, if the antenna beamforming information is antenna weight value information, the energy-saving determination process may calculate a channel power correction value for the antenna based on the antenna weight value information, and then perform an energy-saving determination process using the channel power correction value and the preset energy-saving policy to obtain the first operation control command.

[0028] The channel control circuit module 220 is configured to receive a first operation control command or a second operation control command from the energy-saving control device 210, generate a corresponding energy-saving control signal according to the first operation control command or the second operation control command, and send the energy-saving control signal to the channel controllable link module 230. The channel control circuit module 220 receives the first operation control command or the second operation control command, and generates and outputs a corresponding energy-saving control signal according to the first operation control command or the second operation control command, and the energy-saving control signal may be a channel-off signal, a channel-on signal, a channel tuning signal, a channel wake-up signal, a channel sleep signal, etc. The channels include transmitting channels, receiving channels, and digital intermediate frequency channels, etc.; the channel-off signals include transmitting channel-off signals and receiving channel-off signals, etc.; the channel tuning signals include tuning signals for operating parameters such as transmitting channel operating voltages and matching parameters, etc.; and the channel sleep signals include digital intermediate frequency channel sleep signals and digital intermediate frequency channel wake-up signals, etc., but are not limited thereto.

[0029] The channel-controllable link module 230 is configured to receive an energy-saving control signal from the channel control circuit module 220 and implement energy-saving control for the AAU 110 based on the energy-saving control signal. For example, the digital logic module of the digital intermediate frequency module of the channel-controllable link module 230 may enable operation / disable sleep according to a carrier channel under a channel wake-up signal or a channel sleep signal generated by the channel control circuit module 220, respectively. Each receiving channel or transmitting channel of the channel-controllable link module 230 may be powered on or powered down under a channel off or channel on signal generated by the channel control circuit module 220, respectively. The power devices of each transmitting channel of the channel-controllable link module 230 may be optimally adjusted for parameters such as channel voltage and matching under a channel tuning signal generated by the channel control circuit module 220, respectively, to operate the power devices at the highest efficiency.

[0030] It should be noted that the different components of the energy saving control device 210 may be installed in any one or more of the network management system 130, the BBU 120, and the AAU 110, and are not specifically limited here.

[0031] It should be noted that the first operation control command or the second operation control command may include a channel on / off command, a channel sleep / wake-up command, a channel tuning command, etc. Here, the channel includes a transmitting channel, a receiving channel, a digital intermediate frequency channel, etc., the channel on / off command includes a transmitting channel on / off command and a receiving channel on / off command, etc., the channel tuning command includes a tuning command for an operating parameter such as a transmitting channel operating voltage and a matching parameter, and the channel sleep / wake-up command includes a digital intermediate frequency channel sleep / wake-up command, etc., and is not specifically limited here.

[0032] In addition, the energy-saving control device 210 can communicate with related interaction units in a Massive MIMO system environment. For example, the energy-saving control device can obtain antenna beamforming information transmitted by an AAU in the Massive MIMO system, process the antenna beamforming information to obtain a corresponding first operation control command, and send the first operation control command to the AAU to realize energy-saving control for the AAU.

[0033] Furthermore, the energy-saving control device 210, the channel control circuit module 220 and the channel controllable link module 230 in the AI ​​energy-saving device 200 can be flexibly increased or decreased according to actual application requirements to adapt to the diverse smart energy-saving needs of Massive MIMO AAU devices based on the beamforming AI algorithm in wireless communication systems, effectively achieve energy saving, and reduce the impact on service experience.

[0034] In one embodiment, if the first operation control command is an n-th transmitting channel off command, the channel control circuit module 220 receives the n-th transmitting channel off command from the energy saving control device 210, generates an n-th transmitting channel off signal based on the first operation control command, and transmits the n-th transmitting channel off signal to the n-th transmitting channel of the channel controllable link module 230. The channel controllable link module 230 receives the n-th transmitting channel off signal from the channel control circuit module 220 and adjusts the n-th transmitting channel of the AAU 110 to the off mode based on the channel off signal, thereby achieving power-down energy saving for the n-th transmitting channel. The first operation control command may be turned on based on the n-th transmitting channel to adjust the n-th transmitting channel of the AAU 110 back to the on operating mode. Therefore, the off / on mode for all channels can be achieved based on the corresponding first operation control command. The channel includes a transmitting channel and a receiving channel. This operation control mechanism provides a method for a corresponding preset energy saving policy.

[0035] In one embodiment, if the second operation control command is a channel tuning command, the channel control circuit module 220 receives the channel tuning command from the energy-saving control device 210, generates a corresponding channel tuning signal and a channel tuning target value based on the second operation control command, and transmits the channel tuning signal and the channel tuning target value to the channel of the channel controllable link module 230. The channel controllable link module 230 receives the channel tuning signal and the channel tuning target value from the channel control circuit module 220 and implements energy-saving control for the AAU 110 based on the channel tuning signal and the channel tuning target value. The tunable operating state parameters of the channel may include one or more parameters, such as the drain voltage and gate voltage of the power amplifier and the output matching state of the final-stage power amplifier, but are not limited thereto. Tuning the drain voltage / gate voltage of the power amplifier based on the channel tuning command can improve the dynamic efficiency of the power amplifier and further reduce dynamic power consumption. Tuning the output matching state of the final-stage power amplifier based on the channel tuning command can reduce output power return loss and improve power transmission efficiency. In addition, by adjusting the gate voltage of the power amplifier to an extreme value, the power amplifier can be turned off, that is, the power consumption of the power amplifier can be minimized. In short, by tuning the operating parameters related to the power devices such as the power amplifier on the channel, the operating efficiency at the current power point and frequency point of the channel can be improved, thereby realizing energy saving.

[0036] In one embodiment, if the first operation control command is a digital intermediate frequency channel sleep / wake-up command for the mth carrier of the nth channel, the channel control circuit module 220 receives the digital intermediate frequency channel sleep / wake-up command from the energy-saving control device 210, generates a digital intermediate frequency module enable / disable signal corresponding to the mth carrier of the nth channel based on the first operation control command, and sends the digital intermediate frequency module enable / disable signal to the module of the mth carrier of the nth channel in the channel controllable link module 230. The channel controllable link module 230 receives the digital intermediate frequency module enable / disable signal from the channel control circuit module 220 and adjusts the digital intermediate frequency module of the mth carrier of the nth channel in the AAU 110 to sleep / wake-up mode based on the digital intermediate frequency module enable / disable signal, so that the channel core digital logic module can enable operation or disable sleep as needed to quickly achieve effective utilization of power consumption.

[0037] The base stations and application scenarios described in the embodiments of the present application are intended to more clearly explain the technical solutions of the embodiments of the present application, and do not limit the technical solutions of the embodiments of the present application. With the evolution of base station architecture and the emergence of new application scenarios, the technical solutions of the embodiments of the present application are equally applicable to similar technical problems.

[0038] The structures of the base station 100 shown in FIG. 1, the AAU 110 shown in FIG. 2, and the AI ​​energy-saving device 200 shown in FIG. 3 are not intended to limit the embodiments of the present application, and may include more or fewer components than those shown, or a combination of some components, or a different arrangement of components.

[0039] Based on the above base station 100, the following proposes various embodiments of the energy saving control method of the present application.

[0040] As shown in Fig. 4, Fig. 4 is a flowchart of an energy-saving control method according to one embodiment of the present application, which may be used in an energy-saving control device, such as the energy-saving control device 210 of the AI ​​energy-saving device 200 shown in Fig. 3. The energy-saving control method may include, but is not limited to, step S110, step S120, and step S130.

[0041] Step S110: The antenna information for each channel in the AAU is acquired. Step S120: If the antenna information includes antenna beamforming information, perform energy saving determination processing according to the antenna beamforming information and a preset energy saving policy to obtain a first operation control command.

[0042] In this step, if the antenna information includes antenna beamforming information, an energy saving determination process can be performed based on the acquired antenna beamforming information and a preset energy saving policy to obtain a first operation control command, making it easy to realize energy saving control for the AAU using the first operation control command in subsequent steps.

[0043] The antenna beamforming information may be obtained directly from the beamforming module of the BBU, or may be obtained in other embodiments, for example, the energy-saving control device may obtain the antenna beamforming information via a network management system or via an AAU, which is not specifically limited in this embodiment. Furthermore, the antenna beamforming information may include at least antenna weight value information and further include antenna beamforming information such as AAU operating frequency information, which is not specifically limited here.

[0044] In addition, by performing the energy saving determination process based on the antenna beamforming information and the preset energy saving policy, a first operational control command for channel off, a first operational control command for channel on, a first operational control command for the tuning target value of the operating voltage of each transmitting channel power device, a first operational control command for powering off the transmitting channel, or a first operational control command for the optimal efficiency of each channel power device at the tuned operating voltage, etc., can be obtained, without being limited to specific examples. For example, for a channel power correction value corrected by the antenna beamforming weight value, if the channel power correction value does not exceed the channel power threshold, a first operational control command for channel off is enabled for the corresponding channel, or if the channel power correction value exceeds the channel power threshold, a first operational control command for channel tuning is enabled for the corresponding channel, without being limited to specific examples.

[0045] The preset energy saving policy may be a table created based on past antenna beamforming information, and may include, for example, a table name, a field identifier, an index value, etc. In addition, the preset energy saving policy may be updated, and is not specifically limited here.

[0046] Step S130: The first operation control command is used to realize energy saving control for the AAU.

[0047] In this step, since the first operation control command is obtained in step S120, the first operation control command can be used to perform energy saving control on the AAU, which can flexibly realize energy saving control on the AAU according to actual application demands, adapt to the diversification of energy saving demands, and effectively achieve energy saving.

[0048] In this embodiment, by adopting steps S110 to S130, after obtaining antenna information for each channel in the AAU, if the antenna information includes antenna beamforming information, an energy saving determination process is first performed based on the antenna beamforming information and a preset energy saving policy to obtain a first operation control command, and energy saving control for the AAU is then implemented using the first operation control command. That is, unlike the energy saving mode of timing-off some channels and the channel unification coarse tuning energy saving mode in the related art, the solution of the embodiment of the present application can obtain a currently appropriate first operation control command based on the currently obtained antenna beamforming information, and can allow the AAU to perform energy saving control based on the currently obtained antenna beamforming information. Therefore, the solution of the embodiment of the present application can flexibly implement energy saving control for the AAU according to actual application needs without adding new hardware devices, adapt to diverse energy saving demands, and effectively implement energy saving, thereby optimizing traditional energy saving methods, reducing energy consumption in device operation, and minimizing the impact on service experience.

[0049] The energy saving control of the AAU may be achieved by adjusting the operation mode of the AAU, which may include a channel off mode, a channel on mode, a digital intermediate frequency channel sleep mode, a digital intermediate frequency channel wake-up mode, a channel power amplifier operating voltage tuning mode, and a channel power amplifier load matching tuning mode, etc.

[0050] In one embodiment, as shown in FIG. 5, step S120 is further described, which may include, but is not limited to, step S210 and step S220.

[0051] Step S210: Determine a first candidate policy from among the preset energy saving policies based on the antenna beamforming information.

[0052] In this step, when the energy-saving control device performs an energy-saving judgment process based on the antenna beamforming information and a preset energy-saving policy to obtain a first operation control command, the energy-saving control device may first determine a first candidate policy in the preset energy-saving policy based on the antenna beamforming information, which makes it easy to obtain a control command based on the first candidate policy in a subsequent step.

[0053] It should be noted that the antenna beamforming information may include the time of generation of the antenna beamforming information, the carrier carrying the antenna beamforming information, and other information, which will not be listed one by one here.

[0054] Step S220: Obtain a first operation control command based on the first candidate policy. In this step, since a first candidate policy is obtained in step S210, a first operation control command can be obtained based on the first candidate policy, making it easier to realize energy-saving control for the AAU using the first operation control command in subsequent steps.

[0055] In this embodiment, by adopting the above steps S210 and S220, the energy-saving control device can determine a first candidate policy among the pre-set energy-saving policies based on the antenna beamforming information, and then obtain a first operation control command based on the first candidate policy. In subsequent steps, energy-saving control for the AAU is realized based on this control command, making it easier to adapt to the diversity of AI energy-saving demands of the AAU.

[0056] In one embodiment, as shown in FIG. 6, step S120 is further described, which may include, but is not limited to, steps S310, S320, S330 and S340.

[0057] Step S310: Obtain a channel power correction value for each channel in the AAU according to the antenna beamforming information.

[0058] Step S320: The channel power correction value is input into the energy saving judgment model to perform judgment processing, and a judgment index corresponding to the channel power correction value is obtained.

[0059] In this step, since the channel power correction value of each channel in the AAU is obtained based on the antenna beamforming information in step S310, the energy-saving control device inputs the channel power correction value into the energy-saving judgment model to perform judgment processing, and obtains a judgment index corresponding to the channel power correction value.

[0060] Step S330: A first candidate policy is determined from among the preset energy saving policies based on the determination index.

[0061] In this step, after obtaining the judgment index in step S320, the energy-saving control device can determine a first candidate policy in the pre-set energy-saving policy based on the judgment index, which facilitates obtaining a first operation control command based on this first candidate policy in subsequent steps.

[0062] Step S340: Obtain a first operation control command based on the first candidate policy. In this step, since a first candidate policy is obtained in step S330, a first operation control command can be obtained based on the first candidate policy, making it easier to realize energy-saving control for the AAU using the first operation control command in subsequent steps.

[0063] In this embodiment, by adopting the above steps S310 to S340, the energy-saving control device first obtains a channel power correction value for each channel in the AAU based on the antenna beamforming information, then inputs the channel power correction value for each channel in the AAU into an energy-saving judgment model to perform judgment processing, obtains a judgment index corresponding to the channel power correction value, and determines a first candidate policy in the pre-set energy-saving policies based on the judgment index. Finally, it can obtain a first operation control command based on the first candidate policy. In subsequent steps, it can realize energy-saving control for the AAU based on the control command, thereby making it easier to adapt to the variety of AI energy-saving demands of the AAU.

[0064] This embodiment is an extended method for making a judgment using an AI model. For example, the antenna beamforming information is the antenna distribution weight value of the antenna of each transmission channel of the AAU. A target power corrected by the antenna weight value is obtained based on the antenna distribution weight value. The target power is input into the energy saving judgment model to obtain a judgment index corresponding to the target power. A first candidate policy is determined in the pre-set energy saving policy based on the target power. The first candidate policy turns off each transmission channel whose component power is smaller than the channel power threshold.

[0065] In one embodiment, as shown in FIG. 7, step S210 is further described, and when the antenna beamforming information includes antenna weight value information, this step S210 may include, but is not limited to, step S410 and step S420.

[0066] Step S410: Calculate a channel power correction value for each channel in the AAU based on the antenna weight value information.

[0067] In this step, if the antenna beamforming information includes antenna weight information, when determining the first candidate policy, a channel power correction value of each channel in the AAU can be calculated based on the antenna weight information, and the channel power correction value can be used in the subsequent step to easily determine the first candidate policy in the preset energy-saving policy, which is advantageous for quickly obtaining the first candidate policy and improving the accuracy of the first candidate policy.

[0068] The antenna weight information may be the antenna weight distribution of each channel antenna in the AAU generated by base station beamforming or other information, and is not specifically limited here. The channel power correction value may be the power distribution value of each channel in the AAU or other power value, and is not specifically listed here.

[0069] Step S420: Determine a first candidate policy from among the preset energy saving policies based on the channel power correction value.

[0070] In this step, since the channel power correction value is obtained in step S410, a first candidate policy can be determined in the pre-set energy saving policy based on this channel power correction value, and smart energy saving based on the beamforming AI algorithm can be realized based on this first candidate policy.

[0071] In this embodiment, by adopting the above steps S410 and S420, the energy-saving control device can first calculate the channel power correction value of each channel in the AAU based on the antenna weight value information, and then determine the first candidate policy in the pre-set energy-saving policy based on this channel power correction value.

[0072] The first candidate policy may include a channel-off policy, a channel-on policy, a digital intermediate frequency channel sleep policy, a digital intermediate frequency channel wake-up policy, a channel power amplifier operating voltage tuning policy, a channel power amplifier load matching tuning policy, etc., and is not specifically limited herein. For example, if the antenna weight value information is the antenna weight value distribution of each channel antenna in the AAU generated by base station beamforming, a channel power correction value, which is a power distribution value, for each channel in the AAU is calculated based on this antenna weight value distribution, and a first candidate policy is determined in a pre-set energy-saving policy based on this power distribution value, and smart energy saving based on the beamforming AI algorithm is further achieved based on this first candidate policy.

[0073] In one embodiment, as shown in FIG. 8, step S420 is further described, which may further include, but is not limited to, step S510.

[0074] Step S510: If the channel power correction value is equal to or less than the channel power threshold, obtain a channel power control policy in the preset energy saving policy, and determine the channel power control policy as the first candidate policy.

[0075] In this step, if the antenna beamforming information includes antenna weight value information, the channel power correction value obtained in step S410 is determined, and if this channel power correction value is less than or equal to the channel power threshold, a channel power control policy is obtained in the pre-set energy saving policy, and this channel power control policy is determined as the first candidate policy. Based on this first candidate policy, some channels can independently perform power-on operation and power-down energy saving, and smart power-off energy saving based on the beamforming AI algorithm can be realized.

[0076] Note that the channel power threshold may be 20 dB lower than the average power of the AAU constituent channels, 30 dB lower than the average power of the AAU constituent channels, or another value, and is not specifically limited herein. For example, if the channel power threshold is 20 dB lower, the channel power correction value after correction by the beamforming antenna weight value of the nth channel is 25 dB lower. Because the channel power correction value is smaller than the channel power threshold, the channel power correction value after correction by the beamforming antenna weight value recovers to exceed the power threshold by 2 dB or more (slightly higher than the power threshold to avoid repeated determinations when the channel power correction value approaches the power threshold, which would result in unstable control). Until the activation of the channel power control policy that controls powering on the nth channel is re-determined, a channel power control policy that independently controls powering off the nth channel in the preset energy-saving policy may be applied.

[0077] Furthermore, the channel power control policy may be a channel-off policy, a channel-on policy, or the like, and is not specifically limited here.

[0078] In another embodiment, as shown in FIG. 9, step S420 is further described, which may further include, but is not limited to, step S610.

[0079] Step S610: If the channel power correction value is greater than the channel power threshold, obtain a channel tuning control policy in the preset energy saving policy, and determine the channel tuning control policy as the first candidate policy.

[0080] In this step, if the antenna beamforming information includes antenna weight value information, the channel power correction value obtained in step S410 is used to determine this channel power correction value. If this channel power correction value is greater than the channel power threshold, a channel tuning control policy is obtained in the pre-set energy-saving policy, and this channel tuning control policy can be determined as the first candidate policy. Based on this first candidate policy, the operating voltages of the power devices of most of the transmitting channels can be independently and optimally adjusted to optimize the operating efficiency of the power devices, and smart channel operating parameter tuning energy saving based on the beamforming AI algorithm can be realized.

[0081] It should be noted that the channel power correction value may be the channel target power after being corrected by the beamforming antenna weight value, and is not specifically limited here.

[0082] Note that this channel power threshold may be 20 dB less than the average power of the AAU-constituting channels, 30 dB less than the average power of the AAU-constituting channels, or other values, and is not specifically limited herein. For example, if the channel power threshold is 20 dB less, the actual power after correction by the beamforming antenna weight value of the nth channel is 10 dB less. Since the actual power exceeds the channel power threshold, a channel tuning control policy for controlling the nth channel voltage can be obtained in the preset energy-saving policy. This channel tuning control policy independently adjusts the operating voltage of the power device of the nth transmitting channel to optimize the operating efficiency of the power device at the corresponding power, thereby further achieving energy savings.

[0083] In one example, if the antenna weight value information is an antenna weight value distribution of each channel antenna in an AAU generated by base station beamforming, the AAU channel power configuration information obtained from the AAU can be corrected based on the antenna weight value distribution, thereby obtaining a channel power correction value for each channel in the AAU, and comparing the channel power correction value with a channel power threshold to obtain a comparison result. Next, an energy saving determination process is performed based on the comparison result and a preset energy saving policy, a first candidate policy is determined from the preset energy saving policy, and a first operation control command is obtained based on the first candidate policy, thereby adjusting each channel in the AAU based on the first operation control command, thereby achieving further energy savings.

[0084] Furthermore, the channel tuning control policy may be a tuning control policy in which the operating voltages of power devices that independently adjust some of the transmission channels reach an optimal value, or may be other channel tuning control policies, etc., and is not specifically limited herein. Here, the channel tuning control policy in which the operating voltages of power devices that independently adjust some of the transmission channels reach an optimal value may be a tuning control policy in which the drain operating voltages of power devices that independently adjust some of the transmission channels reach an optimal value, or a tuning control policy in which the gate operating voltages of power devices that independently adjust some of the transmission channels reach an optimal value, and is not specifically limited herein.

[0085] In one embodiment, as shown in FIG. 10, the energy saving control method may further include, but is not limited to, step S710 and step S720.

[0086] Step S710: If the antenna information includes the power configuration information of the AAU, perform an energy saving determination process based on the power configuration information and a preset energy saving policy to obtain a second operation control command.

[0087] In this step, if the antenna information includes the power configuration information of the AAU, an energy saving determination process can be performed based on the acquired power configuration information and a preset energy saving policy to obtain a second operation control command, making it easy to realize energy saving control for the AAU using the second operation control command in a subsequent step.

[0088] Step S720: The second operation control command is used to realize energy saving control for the AAU.

[0089] In this step, since the second operation control command is obtained in step S710, the second operation control command can be used to perform energy saving control on the AAU, and energy saving control on the AAU can be flexibly realized according to actual application demands, adapt to the diversity of energy saving demands, and effectively achieve energy saving.

[0090] In this embodiment, by adopting steps S710 to S720, after obtaining antenna information for each channel in the AAU, if the antenna information includes power configuration information for the AAU, an energy saving determination process is first performed based on the AAU's power configuration information and a preset energy saving policy to obtain a second operation control command, and energy saving control for the AAU is then implemented using the second operation control command. That is, unlike the energy saving mode of timing-off some channels and the channel unification coarse tuning energy saving mode in the related art, the solution of the embodiment of the present application can obtain a second operation control command suitable for the current situation based on the currently obtained power configuration information of the AAU, and can cause the AAU to perform energy saving control based on the currently obtained power configuration information of the AAU. Therefore, the solution of the embodiment of the present application can flexibly implement energy saving control for the AAU according to actual application needs without adding new hardware devices, adapt to diverse energy saving demands, and effectively implement energy saving, thereby optimizing traditional energy saving methods, reducing the energy consumption of equipment operation, and minimizing the impact on service experience.

[0091] In one embodiment, as shown in FIG. 11, step S710 is further described, which may include, but is not limited to, steps S810 and S820.

[0092] Step S810: A second candidate policy is determined from among the energy saving policies that are preset based on the power configuration information.

[0093] In this step, when the energy-saving control device performs an energy-saving judgment process based on the power configuration information and a preset energy-saving policy to obtain a first operation control command, the energy-saving control device can first determine a second candidate policy in the preset energy-saving policy based on the power configuration information, which facilitates obtaining a control command based on the second candidate policy in a subsequent step.

[0094] The power configuration information may include the time of generation of the power configuration information, a carrier carrying the power configuration information, and other information, which will not be listed here one by one.

[0095] Step S820: Obtain a second operation control command based on the second candidate policy. In this step, since a second candidate policy is obtained in step S810, a second operation control command can be obtained based on the second candidate policy, making it easier to realize energy-saving control for the AAU using the second operation control command in subsequent steps.

[0096] In this embodiment, by adopting the above steps S810 and S820, the energy-saving control device can determine a second candidate policy in the energy-saving policy preset based on the power configuration information, and then obtain a second operation control command based on the second candidate policy. In subsequent steps, energy-saving control for the AAU is realized based on this control command, making it easier to adapt to the diversity of AI energy-saving demands of the AAU.

[0097] In one embodiment, as shown in FIG. 12, step S810 is further described, which may include, but is not limited to, step S910 and step S920.

[0098] Step S910: Determine the average power of each channel of the AAU configuration based on the power configuration information.

[0099] In this step, if the antenna information includes power configuration information of the AAU, when determining the second candidate policy, the average power of each channel in the AAU can be determined based on the power configuration information, and the average power can be used in a subsequent step to easily determine the second candidate policy in the preset energy-saving policy. This step can dynamically determine the average power of each channel in the AAU, and easily determine the second candidate policy based on the average power in a timely manner.

[0100] Note that this power configuration information may be the total power of all carrier configurations of the AAU.

[0101] Furthermore, the power configuration information may be obtained by directly inquiring about the configured power from the AAU, or there may be other embodiments, for example, the energy saving control device may directly inquire about the current configured power from the AAU, or may inquire about and calculate all cell power configuration information loaded on the network management system or BBU in which the AAU is located, and this embodiment is not specifically limited to this.

[0102] Step S920: Determine a second candidate policy from the preset energy saving policies based on the average power.

[0103] In this step, since the average power of each channel in the AAU is obtained in step S910, a second candidate policy can be determined in the preset energy-saving policy based on the average power, and operation control instructions can be easily obtained based on this second candidate policy in subsequent steps, which is advantageous for realizing better working conditions of the power amplifiers of each channel based on the second candidate policy and further reducing power consumption.

[0104] In this embodiment, by adopting the above steps S910 and S920, the energy-saving control device first determines the average power of all the transmitting channels of the AAU based on the power configuration information, and then determines a second candidate policy in the pre-set energy-saving policy based on this average power, which is advantageous in improving the efficiency of the tuned operating voltages of the power amplifiers of all the transmitting channels, further reducing power consumption, and realizing energy saving through tuning of the power amplifier voltage AI.

[0105] The second candidate policy may include a channel power amplifier operating voltage tuning policy, a channel power amplifier load matching tuning policy, and other policies, where the channel power amplifier operating voltage tuning policy includes a tuning policy for the transmit channel power device power amplifier average operating voltage, and the channel power amplifier load matching tuning policy includes a tuning policy for the transmit channel power device power amplifier average load matching, although this embodiment is not specifically limited thereto. For example, the total power of all cell configurations of the AAU is obtained, and the average power of all transmit channels of the AAU is determined based on the total power of the AAU configuration, and tuning target values ​​of the power amplifier operating voltages of all transmit channels in the preset energy-saving policy are determined based on the average power. Furthermore, the tuning target values ​​may include a tuning target value for the power amplifier drain voltage, a tuning target value for the power amplifier gate voltage, etc.

[0106] 13, which is a structural schematic diagram of an energy-saving control device 210 according to an embodiment of the present application, includes a data acquisition unit 211 and an energy-saving determination unit 212. The data acquisition unit 211 is configured to acquire antenna information for each channel of the AAU 110. If the antenna information includes antenna beamforming information, the energy-saving determination unit 212 is configured to perform an energy-saving determination process based on the antenna beamforming information and a preset energy-saving policy to obtain a first operation control command and use the first operation control command to control energy saving for the AAU 110. That is, unlike the energy-saving mode and channel-unified coarse tuning energy-saving mode of the related art, which selectively turn off some channels, the solution of the embodiment of the present application can obtain a currently appropriate first operation control command based on currently acquired antenna beamforming information, allowing the AAU to perform energy-saving control based on the currently acquired antenna beamforming information. Therefore, the solution of the embodiment of the present application can optimize traditional energy-saving methods, reduce the energy consumption of device operations, and minimize the impact on service experience without adding new hardware devices.

[0107] Furthermore, the data acquisition unit 211 is installed in any one of the network management system 130, the BBU 120 or the AAU 110, and the energy-saving determination unit 212 is installed in any one of the network management system 130, the BBU 120 or the AAU 110. The data acquisition unit 211 and the energy-saving determination unit 212 are flexibly arranged in the network management system 130, the BBU 120 or the AAU 110. According to actual application requirements, the energy-saving determination unit 212 and the data acquisition unit 211 can be flexibly and conveniently adjusted to realize one or more combined energy-saving technologies, including channel AI off energy-saving, power device working voltage and load matching AI tuning energy-saving, etc., and can further adapt to the variety of AI energy-saving demands of the AAU 110.

[0108] Furthermore, since this energy-saving control device 210 realizes AI energy-saving functions based on the current Massive MIMO base station architecture and current network networking, the deployment of this smart energy-saving energy-saving control device 210 for Massive MIMO AAU equipment based on the beamforming AI algorithm has relatively low hardware costs, construction costs, and maintenance costs.

[0109] 14 , when the data acquisition unit 211 is installed in the BBU 120 and the energy-saving determination unit 212 is installed in the AAU 110, the BBU 120 receives a network management command from the network management system 130, identifies that the network management command includes a beamforming AI smart energy-saving policy, and activates the data acquisition unit 211 to monitor antenna weight value information from the beamforming module of the BBU 120. The BBU 120 determines a power value corrected by the antenna weight value for each channel in the sector area where the AAU 110 is located based on the antenna weight value information, and transmits the antenna weight value information to the AAU 110 via eCPRI. The energy-saving determination unit 212 in the AAU 110 corrects the average power of each channel configuration of the AAU based on the received antenna weight value information to obtain a power correction value for each channel, and performs an energy-saving determination process based on the power correction value for each channel and a preset energy-saving policy to obtain an operation control command. The AAU 110 sends the operation control command to the channel control circuit module 220 of the AAU 110, so that the channel control circuit module 220 generates a corresponding energy-saving control signal based on the operation control command and sends the energy-saving control signal to the channel controllable link module 230 of the AAU 110. The channel controllable link module 230 thereby realizes energy-saving control for the AAU 110 based on the energy-saving control signal, and further realizes smart energy saving based on the beamforming AI algorithm.

[0110] In addition, the energy saving control signal includes an energy saving control signal of a first channel, an energy saving control signal of a second channel, an energy saving control signal of an (n-1)th channel, and an energy saving control signal of an nth channel, where n is a positive integer, and this embodiment does not specifically limit this.

The memory 214 may include high-speed random access memory and may further include non-transitory memory, such as at least one magnetic disk memory device, flash memory device, or other non-transitory solid-state memory device. In some embodiments, the memory 214 may include memory 214 located remotely from the processor 312, and these remote memories may be connected to the processor 312 via a network. Examples of such networks include, but are not limited to, the Internet, a corporate intranet, a local area network, a mobile communication network, and combinations thereof.
