Description

Energy-saving control method, radio frequency equipment and electronic equipment

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an energy saving control method, a radio frequency device, and an electronic device.

Background

With the development of 5G technology, the 5G Base station is also more and more widely distributed, and a complete 5G Base station is composed of equipment, power matching equipment, an iron tower and a machine room, and a main equipment comprises a baseband processing unit (called BBU for short), a HUB (called HUB for short), and a remote radio unit (called RRU for short for english for short Remote Radio Unit), and the signal transmission and reception are completed through the RRU, so that a Power Amplifier (called PA for short for Power Amplifier) in the RRU is required to amplify the Power of the downlink signal before the signal is transmitted due to the attenuation of the signal in the signal transmission process.

In some application scenarios or in some time periods, no downlink signal exists, if the PA is continuously operated, the power consumption of the RRU will be larger. Therefore, in order to reduce the power consumption of the RRU, some energy saving methods are currently proposed to turn off the PA, so as to reduce the power consumption of the RRU, such as symbol/subframe turn-off, channel turn-off, deep sleep turn-off, etc.

Specifically, the symbol/subframe shutdown is to shut down the PA of the unscheduled downlink symbol/slot, thereby reducing the PA power consumption and achieving the energy-saving effect; the channel turn-off is to turn off the PA on the part of the channels without service, thereby achieving the effect of energy saving; the deep sleep is to close the PA, baseband processing, digital intermediate frequency and the like, only the power supply module and the communication interface are reserved for standby in real time, and the mode can achieve a better energy-saving effect, but the base station completely interrupts the service, loses the detection function of user access, namely cannot sense the user access and can only exit the energy-saving mode through a timer, so that when a downlink signal needs to be sent, the PA and other modules need to be restarted, and the waiting process leads to the reduction of the signal throughput of the base station.

Although the above-mentioned coincidence/subframe switch-off, channel switch-off and deep sleep can all achieve the energy-saving effect, there is still the problem that the energy-saving effect is poor or the normal service is affected.

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings. The specific method of operation in the method embodiment may also be applied to the device embodiment or the system embodiment. It should be noted that "a plurality of" is understood as "at least two" in the description of the present application. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. A is connected with B, and can be represented as follows: both cases of direct connection of A and B and connection of A and B through C. In addition, in the description of the present application, the words "first," "second," and the like are used merely for distinguishing between the descriptions and not be construed as indicating or implying a relative importance or order.

Embodiments of the present application are described in detail below with reference to the accompanying drawings.

Currently, a complete main device in a 5G base station includes BBU, HUB and RRU, and signal transmission and reception of the 5G base station are completed by the RRU, and because there is signal attenuation in the signal transmission process, power amplification of a downlink signal needs to be performed by a PA in the RRU before the signal is transmitted, and then the downlink signal after power amplification is transmitted by an antenna, as shown in fig. 1, the RRU in fig. 1 includes programmable array logic (english: field Programmable Gate Array, abbreviated as FPGA), an analog-to-digital conversion module AD/DA, and a Radio Frequency module (english: radio Frequency, abbreviated as RF). The RF includes PA, radio frequency link Switch and (English: low Noise Amplifier, abbreviated as LNA), the Switch connects the PA and LNA separately, when the downlink signal is needed to be sent, the FPGA outputs the downlink signal, then the downlink signal is transmitted to the PA after AD/DA conversion, after the power amplification processing of the downlink signal is carried out by the PA, the downlink signal is switched to the transmitting frequency link by the Switch, finally the downlink signal is sent by the antenna.

Of course, if the antenna receives the uplink signal sent by the terminal, the Switch is firstly switched to the radio-frequency link, then the uplink signal is transmitted to the LNA for power amplification, the uplink signal after power amplification is transmitted to the AD/DA, and finally the uplink signal is transmitted to the FPGA after signal conversion.

Currently, under the condition of less downlink data traffic, the PA is turned off in a symbol/subframe off, channel off and deep sleep mode, so that the RF power consumption is reduced. However, the above-mentioned shutdown method not only has poor energy-saving effect, but also can affect normal service.

In order to solve the problems that the energy saving effect is poor and normal service is affected, the embodiment of the application provides radio frequency equipment which comprises an integrated control module and a radio frequency module, wherein the integrated control module is connected with the radio frequency module. The integrated control module comprises a power detection unit and a gain adjustment unit, wherein the power detection unit is connected with the gain adjustment unit, the radio frequency module comprises a transmitting frequency link, a receiving radio frequency link and a link switcher, the transmitting frequency link is formed by connecting a switch module and a Power Amplifier (PA) in series, and when the power detection unit detects that the signal power value of a downlink signal is smaller than a preset threshold value, the switch module is controlled to bypass the PA, power gain is carried out on the downlink signal through the gain adjustment unit, and the downlink signal is sent through the link switcher.

By the device, when downlink data service does not exist or the downlink data service demand is low, the switch module in the RF is controlled to bypass the PA, so that the power consumption of the PA is reduced to the greatest extent, in order not to affect normal downlink data service, the power of a downlink signal is further increased by the gain adjusting unit, and the downlink signal after the power is increased is sent to the terminal, so that the normal downlink data service is ensured not to be affected after the PA is turned off.

The following describes the technical scheme of the application in detail through the attached drawings and specific embodiments.

Referring to fig. 2, a schematic structural diagram of a radio frequency device provided by the present application is shown, where the radio frequency device is an RRU, and the RRU includes an integrated control module and RF, where the integrated control module is composed of an FPGA and an AD/DA, the FPGA is connected to the AD/DA, and the AD/DA is connected to the RF. In the embodiment of the application, the FPGA may also be replaced by an application specific integrated circuit (in english: application Specific Integrated Circuit, abbreviated as ASIC).

First, a power detection unit and a gain adjustment unit are configured in the FPGA, the power detection unit is connected with the gain adjustment unit, the power detection unit is used for detecting a power value of a signal input into the FPGA, and the gain adjustment module is used for performing gain adjustment on the signal detected by the power detection unit. Of course, if the FPGA is replaced with an ASIC, both the power detection unit and the gain adjustment unit are provided in the ASIC.

In fig. 2, a transmitting frequency link and a receiving radio frequency link are configured in the RF of the RRU, a PA is configured on the transmitting frequency link, an LNA is configured on the receiving radio frequency link, the PA and the LNA are both connected with a link Switch, the Switch is connected to an antenna, when a downlink signal needs to be sent, the Switch is switched to the transmitting frequency link, so that the downlink signal is sent after power gain is performed by the PA, when a signal needs to be received, the Switch is switched to the receiving radio frequency link, then the uplink signal is received by the antenna, and the uplink signal is transmitted to the AD/DA after power gain is performed by the LNA.

Optionally, in this embodiment of the present application, a switch may be disposed in the switch module, as shown in fig. 2, where a first switch SW is configured in the switch module of the RF, where the SW is a single pole double throw switch, an inactive end of the SW is connected to the integrated control module, one active end of the SW is connected to an input end of the PA, and the other active end of the SW is connected to an output end of the PA. As can be seen from fig. 2, PA can be directly bypassed by SW. I.e. the PA can be disconnected directly.

Therefore, in order to ensure accurate turn-off of the PA, in the RRU operation process, the power detection unit in the FPGA detects the signal power value of each received downlink signal in real time, determines the power measurement value corresponding to the N downlink signals after obtaining the signal power value of the N downlink signals, where the power measurement value may be an average value of the signal power values of the N downlink signals, that is, the power measurement value is an average power value, or the power measurement value is a maximum value of the signal power values corresponding to the N downlink signals, and then determines whether the average power of all the signal power values is less than a preset threshold, or whether the maximum value of all the signal power values is less than a preset threshold. For which decision condition is selected, configuration and selection can be performed according to the actual application scenario. If the average power value is used for judging, misjudgment caused by abrupt change of the signal power value of a certain section of downlink signal can be avoided, accuracy of a judging result is ensured, and the average power value is used for judging in the following embodiment.

Therefore, it is determined whether the average power value is smaller than the preset threshold, if the average power value is smaller than the preset threshold, it is indicated that the demand for downlink data service is lower, for example, the user terminal only browses text content in the web page or browses picture content in the web page, and does not have the demand for large data service for watching video. At the moment, the RRU switches the low-power energy-saving mode from the normal working mode, the RRU switches the control SW from the a-connection end to the b-connection end, at the moment, the SW is disconnected with the input end of the PA, the SW is connected with the output end of the PA, and the PA is disconnected, so that the power consumption of the whole RRU is reduced.

Further, in the embodiment of the present application, in order to ensure that the normal downlink data traffic is not affected, after the PA is disconnected, the gain adjustment module in the FPGA is enabled, and after the downlink signal passes through the power detection unit, the gain adjustment unit will perform gain on the power value of the downlink signal, and the gain adjustment unit will perform multiple gain on the downlink signal, so that the downlink signal can be received normally by the terminal. That is, the gain adjusting unit will replace the PA, thus ensuring that the traffic of the terminal is not affected.

It should be noted here that the gain adjusting unit is a function of the FPGA itself, and the power consumption of the gain adjusting unit is in the milliwatt mW level, and the power consumption of the PA is in the watt W level, so that the power consumption of the gain adjusting unit is negligible with respect to the PA.

After the gain adjusting unit adjusts the gain of the power value of the downlink signal, the downlink signal is transmitted to the AD/DA to be converted, then directly transmitted to the Switch through the SW in the RF, and finally the downlink signal is issued through the antenna.

Based on the RRU, under the condition that the downlink data service is less, the PA is directly closed, and under the condition that the PA is closed, the downlink signal can be subjected to gain amplification, and the downlink signal after gain amplification can be received by the terminal, so that the power consumption of the RRU can be reduced to the greatest extent, and the normal downlink data service issuing can be ensured not to be influenced.

Further, in the embodiment of the present application, if the power detection unit detects that the power value of the downlink signal is greater than the preset threshold, for example, when the user terminal plays a video, the user terminal requires a downlink data service with a larger bandwidth. The power amplification factor of the gain adjusting unit is far smaller than that of the PA, so if the gain adjusting unit is used for gain, the power amplification requirement cannot be met. At this time, the RRU will exit the low-power energy-saving mode, the gain adjusting unit will exit, and SW will switch from the b-terminal to the a-terminal, the PA is restarted, and the power amplification of the downlink signal will be completed by the PA. At this point the RRU enters the normal mode of operation. Therefore, when the downlink data service has a larger demand, the power gain of the signal can be switched to the PA in time, and the normal sending and receiving of the downlink signal can be ensured.

Further, in the embodiment of the present application, a structure of a radio frequency device is further provided, and referring to fig. 3, the switch module may further include a first switch SW1 and a second switch SW2.

In fig. 3, the SW1 and the PA are connected in series to form a transmitting frequency link, the inactive end of the SW1 is connected to the integrated control module, one active end of the SW1 is connected to the input end of the PA, and the other active end of the SW1 is connected to the output end of the PA. SW2 and LNA constitute the radio frequency link, and the output of LNA is received to the inactive end of SW2, and the input of link converter is received to one of SW 2's movable end, and the control module is integrated in the connection of the other movable end of SW2.

As can be seen from fig. 3, SW1 can bypass the PA directly, i.e. the PA will be disconnected directly.

Therefore, in order to ensure accurate turn-off of the PA, in the process of RRU operation, the power detection unit in the FPGA detects in real time whether the power value of the received downlink signal is smaller than a preset threshold, if the average signal power value of the N-segment downlink signal detected by the power detection unit is smaller than the preset threshold within the set time range, it indicates that the requirement of the downlink data service is lower, and at this time, the RRU will enter into the low-power energy-saving mode. At this time, the control SW1 is switched from the a-connection terminal to the b-connection terminal, the SW1 is disconnected from the PA input terminal, and the connection between the SW1 and the LNA input terminal is turned on, at this time, the PA is disconnected, so that the power consumption of the entire RRU is reduced. At this time, SW2 is switched from the d-terminal to the c-terminal.

It should be noted that if the RRU sends down a downlink signal, SW2 will be connected to the c moving end at this time, if the RRU receives an uplink signal, SW2 will be connected to the d moving end at this time, so that both uplink and downlink signals can be guaranteed to be normally transmitted.

Further, in this embodiment of the present application, in order to ensure that the normal downlink data traffic is not affected, after the PA is disconnected, the gain adjustment unit in the FPGA will be enabled, after the downlink signal passes through the power detection unit, the gain adjustment unit will perform a multiple gain on the downlink signal, after the gain adjustment unit performs the first gain, the signal is transmitted to the RF, and by controlling SW1 and SW2, the downlink signal after the gain will perform the gain again through the LNA, so that it is ensured that the power value of the downlink signal after the two gains meets the requirement received by the terminal, so that the downlink signal can be normally received by the terminal. That is to say, under the condition that the demand of the downlink data service is lower, the gain adjusting unit and the LNA cooperate to perform the gain of the signal power, and the downlink signal after the power gain can ensure that the terminal can normally receive, so that the service of the terminal is ensured not to be influenced.

It should be understood that when the gain adjusting unit and the LNA perform the gain of the downlink signal at the same time, the gain multiple of the gain adjusting unit should be preset with the gain multiple of the LNA, and the gain effect of the gain adjusting unit and the LNA when the gain is matched with the gain effect of the PA when the low data service is required is ensured to be consistent through the gain multiple setting.

Here, it is to be noted that the gain adjustment unit is a function of the FPGA itself, and the power consumption of the gain adjustment unit is of the mW level, and the power consumption of the PA is of the W level, so that the power consumption of the gain adjustment unit is negligible with respect to the PA. In addition, the LNA is a device that the RF itself has, and therefore does not additionally increase the power consumption of the RF.

After the gain adjusting unit and the LNA perform gain adjustment on the power value of the downlink signal, the downlink signal after the power gain is directly transmitted to the Switch, and finally the downlink signal is issued through the antenna.

Based on the RRU, under the condition that the downlink data service is less, the PA is directly closed, and under the condition that the PA is closed, the downlink signal can be normally subjected to gain amplification processing, so that the power consumption of the RRU can be reduced to the greatest extent, and the normal downlink data service delivery can be ensured not to be influenced.

It should be noted here that, in the embodiment of the present application, in addition to the above manner of adding two switches to the RF, a plurality of switches may be added to the RF, for example, the structure shown in fig. 4 may also achieve the same energy saving effect in the embodiment, so the embodiment of the present application is not limited to a specific structure, and different structures may be used in different application scenarios to achieve energy saving and consumption reduction.

Further, in this embodiment of the present application, if the power detection unit detects that the power value of the downlink signal is greater than the preset threshold, the RRU will exit the low-power energy-saving mode, at this time, the gain adjustment unit will exit, SW1 will switch from the b-connected moving end to the a-connected moving end, SW2 will switch from the c-connected moving end to the d-connected moving end, and power amplification of the downlink signal will be completed through the PA. At this point the RRU enters the normal mode of operation. Therefore, when the downlink data service has a larger demand, the switching can be completed in time, and the normal sending and receiving of the downlink signal when the power demand of the downlink data service is larger can be ensured.

The embodiment of the application also provides an energy-saving control method, and referring to fig. 5, a flowchart of the energy-saving control method provided by the application is shown, and the method can be applied to the radio frequency device, and specifically includes:

s1, receiving a first section of downlink signals;

the first power value is a signal power value of the received first segment downlink signal.

S2, determining whether a first power value of the first section of downlink signals is larger than a preset threshold value;

if yes, go to step S4, if no, go to step S3.

S3, when the power amplifier PA is turned off, if the first power value is not greater than a preset threshold value, the signal gain module gains the signal power value of the first section of downlink signal from the first power value to the second power value;

the second power value is the target power value after gain.

S4, restarting the PA, and performing signal power gain on the first section of downlink signals through the PA.

Specifically, a flow of applying the method to the radio frequency device shown in fig. 2 will be described below.

The FPGA comprises a signal gain module in the running process of the RRU, a power detection unit in the FPGA detects the signal power value of the received N-section downlink signal in real time in the running process of the RRU, after the signal power value of the N-section downlink signal is obtained, a power measurement value corresponding to the N-section downlink signal is determined, wherein the power measurement value can be the average value of the signal power values of the N-section downlink signal, that is, the power measurement value is an average power value, or the power measurement value is the maximum value of the signal power values corresponding to the N-section downlink signal, and then whether the average power of all the signal power values is smaller than a preset threshold value or whether the maximum value of all the signal power values is smaller than the preset threshold value is judged. For which decision condition is selected, configuration and selection can be performed according to the actual application scenario. The average power value is used for determination in the following embodiments, where N is an integer of 2 or more.

And judging whether the average power value is smaller than a preset threshold value, if so, indicating that the requirement of downlink data service is lower, for example, the user terminal only browses text content in a webpage or browses picture content in the webpage, and does not have the requirement of large data service for watching video. At this time, the RRU will switch from the normal operation mode to the low-power energy-saving mode, and the RRU will control the SW shown in fig. 2 to switch from the active a end to the active b end, so that the SW will disconnect the connection with the PA input end and switch on the connection between the SW and the PA output end, and at this time, the PA is disconnected, thereby reducing the power consumption of the entire RRU.

Of course, if the average power value is not smaller than the preset threshold, it indicates that the current requirement of the downlink data service is high, for example, the ue is always watching video, and the PA is kept on.

Here, it may be determined whether the average power value is smaller than a preset threshold, or whether the signal power values corresponding to the N downlink signals are smaller than the preset threshold. Which decision condition to use in particular can be configured or selected according to the actual application scenario.

Further, in order to ensure that normal downlink data traffic is not affected, after the PA is disconnected, the gain adjustment module in the FPGA is enabled, and after the first section of downlink signal passes through the power detection unit, the gain adjustment unit in the gain adjustment module will perform gain on the power value of the first section of downlink signal, and the gain adjustment unit will perform multiple gain on the first section of downlink signal, so that the first section of downlink signal can be normally received by the terminal. That is to say, the gain effect of the gain adjusting unit is consistent with the gain effect achieved by the PA under the low data service requirement, so that the service of the terminal is ensured not to be affected.

After the gain adjusting unit adjusts the gain of the power value of the first segment downlink signal, the downlink signal is transmitted to the AD/DA to be converted, then directly transmitted to the Switch through the SW in the RF, and finally the first segment downlink signal is issued through the antenna.

By the RRU, under the condition that the PA is closed, the downlink signal can be normally subjected to gain amplification, so that the power consumption of the RRU can be reduced to the greatest extent under the condition that the downlink data service is less, and the normal downlink data service issuing can be ensured not to be influenced.

Further, in this embodiment of the present application, if the power detection unit detects that the power value of the first downlink signal is greater than the preset threshold, the RRU will exit the low-power energy-saving mode, at this time, the signal gain unit in the signal gain module is turned off, and SW will be switched from the b-connected end to the a-connected end, the PA is restarted, and signal power amplification of the first downlink signal will be completed by the PA. At this point the RRU enters the normal mode of operation. Therefore, when the downlink data service has a larger demand, the switching can be completed in time, and the downlink signal is ensured to be sent according to the power requirement.

Of course, if the method is applied to the radio frequency device shown in fig. 3, the signal gain module includes a signal gain unit in the FPGA and an LNA in the RF, after the PA is turned off, the signal gain unit in the signal gain module first gains the signal power of the first downlink signal from the first power value to the intermediate power value, and then gains the signal power of the first downlink signal from the intermediate power value to the second power value. The signal gain unit and the LNA cooperate to achieve the same gain effect as the PA under the condition of lower demand of downlink data service.

Of course, if the RRU switches from the low power saving mode back to the normal operation mode, the signal gain unit will be turned off, but the LNA will still maintain the normal operation state. So that the LNA ensures power gain processing of the upstream signal.

By the method, the PA is directly closed under the condition of less downlink data service, so that the power consumption of the RRU is reduced to the greatest extent. And under the condition of closing the PA, the downlink signal can be normally subjected to gain amplification processing, so that the normal downlink data service issuing is ensured not to be influenced.
