[0068] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0069] In the architecture of a picocell, such as Figure 1 As shown, a baseband unit (BBU) can connect to one or more EUs, and an EU can connect to one or more RRUs. The EU, RRU, and BBU constitute a digital indoor distribution system. The EU can power the RRU via Power over Ethernet (PoE) or a fiber optic composite cable.

[0070] In scenarios where the EU powers the RRU, such as Figure 2As shown, after the EU provides 48V DC power to the RRU, the first-stage DC power supply unit inside the RRU converts the 48V voltage into an intermediate voltage, such as 18V, 12V or 9V. Then, the second-stage DC power supply unit and other power circuits inside the RRU convert the intermediate voltage into a lower voltage, such as 5V, 3.3V and 1.0V, to be supplied to various chips or load circuits for operation.

[0071] With a fixed transmit power for the RRU, the power consumption of various chips and load circuits is also fixed. However, the power efficiency affects the overall power consumption of the RRU. Power efficiency is related to factors such as input voltage, output voltage, ambient temperature, and load variations. With a fixed input voltage and intermediate voltage, changes in ambient temperature or service conditions may increase or decrease the load current of the first-stage and second-stage DC power supply units, leading to changes in power efficiency. This can reduce the overall power efficiency of the RRU, thus altering its power consumption.

[0072] In summary, in scenarios where the power supply unit powers the RF unit, there is currently no solution for optimizing the power efficiency of the RF unit to reduce overall power consumption, thereby making the system more energy-efficient and environmentally friendly.

[0073] Based on this, in various embodiments of this application, when the power supply unit supplies power to the radio frequency (RF) unit, by real-time monitoring of the RF unit's power consumption status, the RF unit can adjust its internal intermediate voltage in a timely manner based on the adjustment signal to determine the optimal operating voltage for power consumption. In this way, without changing the input voltage, the RF unit can optimize power efficiency by adjusting the intermediate voltage, thereby achieving the goal of energy saving and low power consumption for the RF unit.

[0074] This application provides a voltage adjustment method, such as... Figure 3 As shown, applied to a first device, the method includes:

[0075] Step 301: During the process of the second device supplying power to the first device, a first signal sent by the second device is received. The first signal is used to indicate the adjustment of the first voltage between the first unit and the second unit of the first device. The first signal is sent based on the detection result associated with the power consumption of the first device. The first unit is used to adjust the second voltage provided by the second device to the first voltage. The second unit is used to supply power to the chip of the first device using the first voltage. The first device has a conversion function between digital signals and radio frequency signals.

[0076] Step 302: Based on the first signal, adjust the first voltage so that the power consumption of the first device meets the requirements.

[0077] In practical applications, the first device can be understood as a radio frequency unit in a base station, capable of at least converting between digital and radio frequency signals. For example, in a pico base station architecture, the first device may include an RRU (Remote Receiver Unit). This application embodiment does not limit the type of the first device, as long as its function is implemented. Furthermore, the second device can be understood as a power supply unit, capable of at least supplying power to the first device and monitoring its power consumption status. For example, in a pico base station architecture, the second device may include an EU (Engineer Unit). This application embodiment does not limit the type of the second device, as long as its function is implemented.

[0078] In practical applications, the second device can provide the second voltage to the first device to power the first device. The second voltage can be understood as the power supply voltage output by the second device or the input voltage of the first unit. The value of the second voltage can be set as needed, such as 48V. This application embodiment does not limit this. The second device can be connected to the first device through a power cord and / or data cable, such as an optical fiber composite cable, an independent power cord, an optical fiber (or network cable), or a PoE power and network cable. This application embodiment does not limit the connection method between the second device and the first device.

[0079] Here, during the power supply process described above, the second device can detect the power consumption of the first device in real time and send the first signal to the first device based on the detection result, so that the first device can trigger the voltage adjustment process. The first signal can be called a voltage adjustment signal, power adjustment command, or power adjustment message, etc. The name of the first signal is not limited in this application embodiment, as long as its function is realized. The signal can be transmitted through the channel established between the first device and the second device (which can also be called an operation and maintenance channel, which is not limited in this application embodiment).

[0080] It should be noted that the second device may include multiple ports. In the case of multiple first devices, the second device can supply power to each first device through multiple ports. During this process, the second device can monitor the power consumption status of each first device and send the first signal through the established channel.

[0081] In practical applications, the first device may include one or more first units (the number of first units is not limited in this embodiment), a second unit, and the chip. The one or more first units are used to convert the second voltage to the first voltage, and the second unit is used to power the chip (such as an analog circuit chip, a core chip, or a digital circuit chip) using the first voltage. The first voltage can be referred to as an intermediate voltage (which can be represented as Vout1). As can be seen from the above description, the first voltage can be understood as the output voltage of the last first unit in the one or more first units, or it can be understood as the input voltage of the second unit.

[0082] For example, suppose the first device includes a first unit 1, a second unit 1, and a chip. The first unit 1 is used to convert a second voltage (e.g., 48V) into a first voltage (e.g., 3.3V), and the second unit 1 is used to convert the first voltage into a fifth voltage (e.g., 5V) and use the fifth voltage to power the chip of the first device; that is, the first voltage can be the output voltage of the first unit 1, which is also the input voltage of the second unit 1.

[0083] For example, suppose the first device includes two first units (first unit 2 and first unit 3), a second unit 2, and a chip. The first unit 2 is used to convert the second voltage (e.g., 48V) into a sixth voltage (e.g., 12V). The first unit 3 is used to convert the sixth voltage into a first voltage (e.g., 3.3V). The second unit 2 is used to convert the first voltage into a fifth voltage and use the fifth voltage to power the chip of the first device. That is, the first voltage can be the output voltage of the first unit 3, which is also the input voltage of the second unit 2.

[0084] In practical applications, after receiving the first signal, the first device can determine the adjustment range of the first voltage and adjust the first voltage within the adjustment range.

[0085] Specifically, in one embodiment, the implementation of step 302 may include:

[0086] A first range is defined, which includes the adjustment range of the first voltage;

[0087] The first voltage is adjusted using the first range.

[0088] In practical applications, for the first range, the first device can determine the first range based on the voltage range requirements of the first unit and the second unit.

[0089] Specifically, in one embodiment, determining the first range includes:

[0090] A second range and a third range are determined, wherein the second range includes the output voltage range of the first unit, and the third range includes the input voltage range of the second unit;

[0091] The first range is determined using the second range and the third range.

[0092] In practical applications, the second range can be understood as the output voltage range that the first unit can support, and the third range can be understood as the input range that the second unit can support.

[0093] In practical applications, the first device can read the second range and the third range from the local parameter information, respectively. This application embodiment does not limit the method of obtaining the second range and the third range.

[0094] Here, in determining the first range, the first device may also combine the output or input voltage requirements of the first unit and the second unit to jointly determine the first range.

[0095] Specifically, in one embodiment, determining the first range using the second range and the third range includes:

[0096] Determine a third voltage, which includes the input voltage required by the chip;

[0097] The first range is determined using the third voltage, the second voltage, the second range, and the third range.

[0098] The third voltage can be understood as the input voltage required by the chip, or as the output voltage of the second unit.

[0099] In practical applications, the first device can obtain the third voltage from local parameter information; use the second range and the third range to determine a fourth range that can characterize the overlapping region (also known as the intersection region); and use the third voltage, the second voltage, and the fourth range to determine the first range.

[0100] For example, assuming the second range is 4V to 36V, the third range is 3V to 17V, the third voltage is 5V, and the second voltage is 48V, the first device determines a fourth range of 3V to 17V based on the second range and the third range; using the fourth range, the second voltage, and the third voltage, the first device determines the first range to be 6V to 17V.

[0101] In practical applications, without changing the external input voltage (i.e., the second voltage) and the internal chip load voltage (i.e., the third voltage), the first device can divide the first range into different voltage levels to adjust the first voltage to different voltage levels.

[0102] Specifically, in one embodiment, adjusting the first voltage using the first range includes:

[0103] Using the first range, determine M fourth voltages, where M is an integer greater than or equal to 2;

[0104] The first voltage is adjusted using each of the M fourth voltages.

[0105] The fourth voltage can be understood as the adjustment voltage or working voltage of the first voltage during the adjustment process, and different voltage levels correspond to different fourth voltages.

[0106] In practical applications, the first device can determine the interval of voltage levels (which can be set as needed, for example, to 1V); using the first range and the determined interval, M fourth voltages are determined, and then the first voltage is sequentially adjusted to M fourth voltages so that one fourth voltage can be selected from the M fourth voltages as the adjusted first voltage.

[0107] For example, assuming the first range is 6V to 17V, the first device can determine 12 voltage levels with 1V intervals, each voltage level corresponding to a fourth voltage (specifically corresponding to 6V, 7V, 8V, 9V, 10V, 11V, 12V, 13V, 14V, 15V, 16V, 17V); of course, the first device can also determine 24 voltage levels with 0.5V intervals, each voltage level corresponding to a fourth voltage.

[0108] It should be noted that the adjustment of the first voltage (specifically including increasing or decreasing) can be achieved by the first device based on the voltage division of a digitally controlled adjustable resistor, or by generating an analog signal through a digital-to-analog converter (DAC), or by setting the high and low levels of a general purpose input / output (GPIO). This application embodiment does not limit this.

[0109] In practical applications, during the adjustment process, the first device can perform power consumption detection through the second device in order to select a fourth voltage based on the power consumption situation.

[0110] Specifically, in one embodiment, when adjusting the first voltage using each of the M fourth voltages, the method may further include:

[0111] Send a second signal to the second device, the second signal being used to indicate the measurement of the power consumption of the first device during voltage adjustment;

[0112] Receive the measurement results sent by the second device, the measurement results including the power consumption of the first device corresponding to the M fourth voltages;

[0113] Using the measurement results, a fourth voltage is selected from M fourth voltages, and the first voltage is adjusted to the selected fourth voltage.

[0114] Here, during the voltage adjustment process, the first device can sequentially adjust the first voltage to M fourth voltages. During this process, the power efficiency of the first unit and the second unit changes, causing the overall power efficiency of the first device to change, which in turn causes the actual power consumption of the first device to change. Therefore, the second device can measure the power consumption of the first device corresponding to each fourth voltage in real time, and sequentially send the power consumption of the first device corresponding to the M fourth voltages to the first device so that the first device can compare and analyze them to determine how to adjust the first voltage. The measurement results can be transmitted through a channel established between the first device and the second device.

[0115] For example, assuming the first range is 6V to 17V, such as Figure 4 As shown, the first device can adjust the first voltage using 12 fourth voltages respectively, and obtain the power efficiency trends of the first unit and the second unit relative to the fourth voltages. Simultaneously, the first device can also use the power efficiency trends of the first unit and the second unit relative to the fourth voltages to obtain the power efficiency trend of the first device relative to the fourth voltages. The power efficiency of the first device can be expressed as the product of the power efficiency of the first unit and the power efficiency of the second unit. From... Figure 4 It can be seen that during the voltage adjustment process, there is a fluctuation of 5.6% between the maximum power efficiency (81.1%) and the minimum power efficiency (74.5%) of the first device.

[0116] In practical applications, by comparing the power consumption of the first device corresponding to the M fourth voltages, the first device can determine the minimum power consumption and adjust the fourth voltage corresponding to the minimum power consumption to the first voltage. In other words, the first device can use the fourth voltage corresponding to the minimum power consumption as the optimal operating voltage of the first voltage.

[0117] For example, in Figure 4 On the basis of, such as Figure 5As shown, the first device can obtain the power consumption trend of the first device relative to the 12 fourth voltages through the second device. From Figure 5 It can be seen that there is a fluctuation of 3.94W between the maximum power consumption (48.89W) and the minimum power consumption (44.65W) of the first device. In other words, for a single device, a power consumption reduction can be achieved within a range of 3.94W.

[0118] Accordingly, embodiments of this application also provide a voltage adjustment method, applied to a second device, such as... Figure 6 As shown, the method includes:

[0119] Step 601: During the process of supplying power to the first device, the power consumption of the first device is detected, and the detection result is obtained;

[0120] Step 602: Based on the detection result, send a first signal to the first device. The first signal is used to instruct the adjustment of the first voltage between the first unit and the second unit of the first device. The first unit is used to adjust the second voltage provided by the second device to the first voltage. The second unit is used to power the chip of the first device using the first voltage. The first device has a conversion function between digital signals and radio frequency signals.

[0121] In practical applications, in step 601, the second device can read the current and voltage values ​​of the first device in real time, and use the read current and voltage values ​​to obtain the detection result, which can be expressed as the product of the current and voltage values.

[0122] Here, after obtaining the detection result, the second device can analyze the detection result to determine whether to send the first signal to trigger the first device to adjust the first voltage.

[0123] Specifically, in one embodiment, the implementation of step 602 may include:

[0124] Based on the detection results, it is determined that a first condition is met, wherein the first condition includes one of the following:

[0125] The power consumption of the first device is greater than the first threshold.

[0126] The power consumption change of the first device within a first time period is greater than the second threshold.

[0127] The operating time of the first device is longer than that of the second device;

[0128] Send the first signal to the first device.

[0129] In practical applications, when the operating temperature of the first device changes or the service status (such as the access status or resource utilization of the first device) changes, the actual power consumption will change. Therefore, by comparing and analyzing the detection results, the second device can determine whether the first device has deviated from the optimal operating voltage, and thus determine whether to send the first signal.

[0130] Here, if the power consumption of the first device is greater than the first threshold (which can be set as needed), the second device can send the first signal to the first device; if the power consumption change of the first device within a first duration is greater than the second threshold (which can be set as needed), the second device can send the first signal to the first device; if the working duration of the first device meets the second duration, the second device can send the first signal to the first device (which can also be understood as sending the first signal using a timed task).

[0131] In addition, in a scenario where the second device supplies power to multiple first devices simultaneously, the second device can also compare the power consumption of the multiple first devices, select one or more first devices with the highest current power consumption, and send the first signal to the selected first device.

[0132] In practical applications, during the voltage adjustment process of the first device, the second device can monitor the power consumption of the first device in real time so that the first device can know how to adjust the first voltage.

[0133] Based on this, in one embodiment, the method may further include:

[0134] Receive a second signal sent by the first device, the second signal being used to indicate the measurement of the power consumption of the first device during voltage adjustment;

[0135] Based on the second signal, the power consumption of the first device is measured to obtain a measurement result. The measurement result includes the power consumption of the first device corresponding to M fourth voltages, where M is an integer greater than or equal to 2.

[0136] The voltage adjustment method provided in this application embodiment involves a first device receiving a first signal sent by the second device during the process of a second device supplying power to the first device. This first signal instructs the adjustment of a first voltage between a first unit and a second unit of the first device. The first signal is sent based on a detection result related to the power consumption of the first device. The first unit adjusts a second voltage provided by the second device to the first voltage. The second unit uses the first voltage to supply power to the chip of the first device. The first device has a digital signal and radio frequency signal conversion function. Based on the first signal, the first voltage is adjusted to ensure that the power consumption of the first device meets requirements. In the technical solution provided in this application embodiment, during the process of supplying power to a first device (e.g., an RRU), the second device (e.g., an EU) sends a voltage control signal (i.e., a first signal) to the first device based on the power consumption state of the first device. This enables the first device to adjust the intermediate voltage (i.e., the first voltage) between the first unit and the second unit to optimize the power efficiency of the first device, thereby reducing its power consumption. Thus, when the external environment or business conditions change, the first device can promptly trigger a voltage adjustment process to improve power efficiency, thereby ensuring the overall power consumption of the first device.

[0137] The following section provides a more detailed description of this application with reference to application examples.

[0138] In the application examples of this application, an energy-saving scheme for pico base stations is proposed; specifically, such as... Figure 7 As shown, a pico base station mainly consists of an EU (i.e., the first device mentioned above) and an RRU (i.e., the second device mentioned above). One EU connects to one or more RRUs, such as RRU-1, RRU-2, and RRU-n. The EU includes a first processor and a power management module. The first processor is used to interact with the RRU via an operation and maintenance channel to exchange commands and messages. The power management module is used to detect the power of the RRU and provide a power supply voltage (i.e., the second voltage mentioned above). The RRU includes a second processor, a first-stage power conversion module (i.e., the first unit mentioned above), a second-stage power conversion module (i.e., the second unit mentioned above), other power circuits, chips, and load circuits. The second processor is used to interact with the EU via an operation and maintenance channel to exchange commands and messages. The first-stage power conversion module is used to convert the power supply voltage to an intermediate voltage (i.e., the first voltage mentioned above). The second-stage power conversion module is used to convert the intermediate voltage to the voltage required by other power circuits, chips, and load circuits.

[0139] Here, the process of power consumption adjustment by the pico base station is as follows: Figure 8 As shown, it includes the following steps:

[0140] Step 801: Power on the EU;

[0141] Step 802: The EU's power management module outputs the supply voltage, enabling the RRU to start after receiving the supply voltage;

[0142] Step 803: The RRU and EU establish an operation and maintenance channel;

[0143] Step 804: The EU measures the current and voltage of the RRU;

[0144] Here, the EU's first processor monitors the voltage and current of each RRU and calculates the real-time power consumption data of the RRU.

[0145] Step 805: The EU sends power consumption data to the RRU;

[0146] Among them, the calculated power consumption data is sent to the RRU through the operation and maintenance channel.

[0147] Step 806: The RRU receives and stores power consumption data;

[0148] Step 807: The EU determines to initiate a power adjustment command (i.e., the first signal mentioned above);

[0149] Here, the EU can analyze the power consumption data of each RRU or compare the power consumption data of multiple RRUs to determine whether to send a power adjustment command to the RRU. If the power change of a single RRU exceeds a threshold (i.e., the second threshold mentioned above), a power adjustment command is sent; if there is an RRU with the highest power consumption among multiple RRUs, a power adjustment command is sent to the RRU with the highest power consumption; if a certain duration is met (i.e., the second duration mentioned above), a power adjustment command is sent; if the power of a single RRU exceeds a threshold (i.e., the first threshold mentioned above), a power adjustment command is sent.

[0150] It should be noted that the execution order of steps 804 and 807 is not important.

[0151] Step 808: The EU sends a power adjustment command to the RRU through the operation and maintenance channel;

[0152] Step 809: After receiving the power adjustment command, the RRU starts the Vout1 voltage adjustment of the first-stage power conversion module;

[0153] Here, assuming the EU supplies 48V to the RRU, the RRU can convert 48V to an intermediate voltage through the first-stage power conversion module; through the second-stage power module, it can output various voltages required by the subsequent circuits, such as converting the intermediate voltage to 3.3V with an equivalent load current of 4A to power the digital circuit chips and interface I / O in the RRU; converting the intermediate voltage to 5V with an equivalent load current of 3A to power the analog circuit chips in the RRU; and converting the intermediate voltage to 1V with an equivalent load current of 8A to power the core of the core chip.

[0154] In practical applications, the RRU can determine the adjustment range of the first-stage power conversion module (i.e., the first range mentioned above) based on the adjustable output range of the first-stage power conversion module (i.e., the second range mentioned above), the supported input range of the second-stage power conversion module (i.e., the third range mentioned above), the input voltage of the first-stage power conversion module, and the required output voltage of the second-stage power conversion module (i.e., the third voltage mentioned above). For example, assuming the output range of the first-stage power conversion module can range from a maximum of 36V to a minimum of 4V, the first-stage power conversion module supports a maximum input voltage of 17V, and the required output voltage is 5V, then the RRU can set the adjustable range of the intermediate voltage to 17V-6V.

[0155] Here, the RRU can divide the intermediate voltage operating voltage into M levels (i.e., the aforementioned M fourth voltages) based on the adjustable maximum and minimum values ​​of the intermediate voltage. For example, the range from 17V to 6V can be divided into 12 levels at 1V intervals, or 24 levels at 0.5V intervals. Then, within the adjustable range, the levels are sequentially increased or decreased, while simultaneously receiving power consumption data (i.e., the aforementioned power consumption data) sent by the EU.

[0156] Step 810: The RRU determines whether voltage adjustment is complete;

[0157] If the RRU has completed the adjustment of M gears, then the voltage adjustment is confirmed to be complete, and step 811 is executed; otherwise, step 809 is executed.

[0158] Step 811: RRU sets the optimal Vout1 operating point;

[0159] Here, the RRU determines the level corresponding to the minimum power consumption by comparing the power consumption data corresponding to M levels, and adjusts the intermediate voltage to that level.

[0160] Step 812: EU determines whether voltage adjustment is complete;

[0161] If the voltage adjustment of M levels is completed, the RRU notifies the EU that the voltage adjustment is complete, so that the EU executes step 813; otherwise, the power consumption data of the RRU is continuously monitored.

[0162] Step 813: The EU continuously monitors the RRU power consumption;

[0163] Step 814: The EU determines whether the power consumption change exceeds the threshold;

[0164] If the power consumption change exceeds the threshold, step 816 is executed; otherwise, step 815 is executed.

[0165] Step 815: EU compares and analyzes the power consumption data of multiple RRUs;

[0166] Here, the EU can compare the real-time power consumption data of different RRUs horizontally, determine the RRU with the highest current power consumption, and initiate a power consumption adjustment command. In this way, all RRUs can be in a relatively optimal voltage operating point.

[0167] Step 816: The EU initiates a power adjustment command.

[0168] Here, the actual power consumption changes when the RRU's operating temperature or service status changes. Therefore, the EU can identify whether the RRU has deviated from its optimal operating point by comparing and analyzing power consumption data over a continuous period. If the power consumption change exceeds a threshold, indicating that the RRU has deviated from its optimal operating voltage, the EU can initiate a power adjustment command again.

[0169] In this application example, the coordinated operation of the EU and RRU in the pico base station enables the RRU to find the optimal power consumption operating point under different service conditions. This improves the overall power efficiency of the RRU and reduces its overall power consumption without changing the original RRU input voltage. During this process, the EU can trigger power adjustment tasks based on a horizontal comparison of the power status of multiple RRUs, ensuring that the RRU always operates at an optimal efficiency point. This achieves the goal of energy saving and power reduction for the entire base station.
