It should be understood that the embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. In the present application, the embodiments and features of the embodiments may be arbitrarily combined with each other without conflict.

The terms first, second and the like in the description and in the claims, and the drawings described above, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In the mobile communication system, as shown in fig. 1, a base station 100 includes a baseband module 110 and a radio frequency unit 120, and the baseband module 110 transmits a radio frequency signal to a terminal 200 through the radio frequency unit 120. For example, in the case of explosive increase of data volume, the macro station only carries less than 30% of the data volume, that is, the indoor communication system (e.g., active room subsystem, passive room subsystem) is the main carrier of the data volume. The active indoor subsystem has to be configured with a large number of rf units 120 to meet the communication requirement due to the limitation of its coverage area, and the large-scale configuration of the rf units 120 causes huge energy consumption. Therefore, higher requirements are put on energy saving and consumption reduction of the rf unit 120.
Based on the above, the present invention provides a radio frequency unit power control method, an electronic device, and a storage medium, which can reduce energy consumption of a radio frequency unit without affecting user experience.
It should be noted that the electronic device according to the embodiment of the present invention may be the radio frequency unit 120, or may be the base station 100 including the baseband module 110 and the radio frequency unit 120. As shown in fig. 1, the baseband module 110 includes a baseband processing unit 111 and a bridge device 112, the baseband processing unit 111 is connected to the bridge device 112, and the bridge device 112 is connected to the rf unit 120.
In some embodiments, the baseband module 110 includes only the baseband processing unit 111, and the baseband processing unit 111 is directly connected to the rf unit 120.
In some embodiments, the baseband processing unit 111 is a BBU (Building Base band unit), distributed in the room subsystem.
It is understood that, in practical applications, as shown in fig. 2, the baseband processing unit 111 may be connected to a plurality of bridge devices 112, and each bridge device 112 may also be connected to a plurality of rf units 120, so as to enable access of more terminals 200.
The technical solution of the present invention will be described below with reference to specific examples.
In a first aspect, as shown in fig. 3, an embodiment of the present invention provides a radio frequency unit power control method, which is applied to an electronic device. The electronic device may be a radio frequency unit, or may be a base station including a baseband module and a radio frequency unit. The method comprises the following steps:
step S110: acquiring the utilization state information of the unit channel of the radio frequency unit.
In some embodiments, the utilization state information of the unit channel of the radio frequency unit is proportional to the access amount of the user terminal, i.e., the higher the access amount of the user terminal is, the larger the utilization state information value of the unit channel of the radio frequency unit is.
In some embodiments, step S110 is applied to the base station, and the baseband module is used to monitor the user terminal access amount of the radio frequency unit in real time, and generate the utilization state information of the unit channel of the radio frequency unit according to the user terminal access amount. In other embodiments, step S110 is applied to the radio frequency unit, and the radio frequency unit receives the utilization state information of the unit channel of the radio frequency unit, which is sent by the baseband module.
In some embodiments, the Radio frequency Unit may be a Remote Radio Unit (RRU), an Active Antenna Unit (AAU), an Antenna Filter Unit (AFU), or other devices that can implement the function of the Radio frequency Unit. If the method is applied to an active or passive room subsystem, the radio frequency unit may be a micro radio frequency unit, such as a micro RRU.
Step S120: and adjusting the current switch state of the unit channel to the switch state of the target according to the utilization state information.
In some embodiments, as described above, the radio frequency unit receives the utilization state information of the unit channel of the radio frequency unit sent by the baseband module, and adjusts the current on-off state of the unit channel of the radio frequency unit to the target on-off state according to the utilization state information.
Because the utilization state information of the unit channel of the radio frequency unit is generated according to the access amount of the user terminal, the switching state of the unit channel of the radio frequency unit is adjusted according to the utilization state information of the unit channel of the radio frequency unit, so that the switching state of the unit channel of the radio frequency unit is adaptively adjusted along with the access amount of the user terminal, the user experience is not influenced, and the effects of energy conservation and consumption reduction of the radio frequency unit can be achieved.
It should be noted that the switching state of the unit channel of the rf unit includes on or off, and more specifically, refers to the state of the unit channel of the rf unit being on or off. In some embodiments, the unit channel of the radio frequency unit is a symbol channel. The symbol channel is a time unit for carrying data and is also the minimum data scheduling unit. It can be understood that the symbol channel is selected as the unit channel to be adjusted, and the power is more finely and flexibly controlled, so that the matching precision of the switch state of the final adjustment target and the utilization state information of the unit channel is higher.
It is understood that the unit channel of the radio frequency unit may also be a slot (slot) channel or a frame channel. In the field of communications, a time period is set when processing data, and assuming that one period is 10ms, 10ms is divided into 20 slot channels, i.e., slot channels 0 to 19. Each slot channel is divided into 14 symbol channels (for example, OFDM symbols, where one symbol channel corresponds to one time domain resource location), that is, symbol channel 0 to symbol channel 13.
In some embodiments, as shown in fig. 4, step S120 includes the steps of:
step S121: and according to the utilization state information, the power amplifier corresponding to the unit channel is turned on or off so as to adjust the current switching state of the unit channel to the target switching state.
In some embodiments, the radio frequency unit adjusts the on-off state of the unit channel by turning on or off a power amplifier corresponding to the unit channel. It can be understood that the power amplifier refers to a power amplifier, turning on the power amplifier refers to powering on the power amplifier, and turning off the power amplifier refers to powering off the power amplifier.
It should be noted that the power amplifier corresponding to the unit channel is turned on and the power amplifier corresponding to the unit channel is turned off and the unit channel is turned off.
In some embodiments, as shown in fig. 5, step S120 includes the steps of:
step S122: and according to the utilization state information, turning on or turning off the data of the unit channel so as to adjust the current switching state of the unit channel to the target switching state.
In some embodiments, the data of the unit channel is turned on according to the utilization status information, that is, the unit channel normally transmits data, and the unit channel is turned on. Similarly, according to the utilization status information, the data of the unit channel is closed, that is, the unit channel does not transmit data, and the unit channel is closed at this time. And adjusting the current switching state of the unit channel to the target switching state by turning on or off the data of the unit channel. In some embodiments, the data of the unit channel is IQ data (in-phase/quadrature data) carried by the unit channel.
In some embodiments, as shown in fig. 6, step S120 includes the steps of:
step S123: according to the utilization state information, turning on or turning off the data of the unit channel;
step S124: detecting the power of a unit channel;
step S125: and according to the detection result, turning on or turning off the power amplifier corresponding to the unit channel so as to adjust the current switching state of the unit channel to the target switching state.
In some embodiments, the power of the unit channel is detected according to data of the unit channel that is turned on or off using the state information. In combination with the above, if the unit channel is a symbol channel, the power of the unit channel is the power of IQ data (in-phase/quadrature data) carried by the symbol channel. For example, the symbol channel carries 30 bits of IQ data, m bits of in-phase data, n bits of quadrature data, and m + n is 30, the power per channel is m 2+ n 2. The radio frequency unit opens or closes the power amplifier corresponding to the unit channel according to the result of the detected power, and specifically, if the detected power m ^2+ n ^2 of the unit channel is 0, the power amplifier corresponding to the unit channel is closed; and if the detected power m 2+ n 2 of the unit channel is normal, starting the power amplifier corresponding to the unit channel so as to adjust the current switching state of the unit channel to the target switching state.
In combination with the above, adjusting the current switch state of the unit channel to the target switch state may include three implementation manners: (1) turning on or turning off a power amplifier corresponding to the unit channel; (2) turning on or off data of the unit channel; (3) and turning on or turning off data of the unit channel, detecting the power of the unit channel, and turning on or turning off the power amplifier corresponding to the unit channel according to the detection result. In practical application, the selection can be performed according to the situation.
In some embodiments, the status information is used to classify according to rank. When the utilization state information is nth level utilization state information, N is a positive integer greater than or equal to 1, and correspondingly, as shown in fig. 7, step S120 includes:
step S123: and adjusting the current on-off state of the unit channel to the on-off state of the target corresponding to the N-th level utilization state information according to the N-th level utilization state information and a preset channel control rule.
In some embodiments, in order to better enable the switching state of the unit channel of the radio frequency unit to be adaptively adjusted along with the access amount of the user terminal, multiple levels of utilization state information may be set, and each level of utilization state information corresponds to different access amounts of the user terminal, that is, as the access amount of the user terminal gradually decreases, part of the unit channel may be gradually closed in a step shape, which is flexible and energy-saving without affecting user experience. When the utilization state information is the nth level utilization state information, the radio frequency unit adjusts the current on-off state of the unit channel of the radio frequency unit to the on-off state of the target corresponding to the nth level utilization state information according to the nth level utilization state information and a preset channel control rule.
In some embodiments, the preset channel control rules include:
the nth level utilizes a mapping of the state information and the on-off state of the target.
In some embodiments, the utilization status information is divided according to a hierarchy, with each level of utilization status information mapping the switching status of a target. It should be noted that the switch state of the target refers to which unit channels of the rf unit are turned on and which unit channels are turned off, or several unit channels are turned on and several unit channels are turned off.
Taking the example that the utilization state information is divided into four levels (including the first level utilization state information, the second level utilization state information, the third level utilization state information, and the fourth level utilization state information), the unit channel is a symbol channel, and there are 14 symbol channels in total, the following description is made:
if the switch state of the target mapped by the first level using the state information is that the symbol channel is fully opened, the symbol channel is completely opened according to the first level using the state information;
and the second level utilizes the switching state of the target mapped by the state information, and if the first condition is the state A (2 symbol channels are turned off and 12 symbol channels are turned on), the current switching state of the symbol channels is adjusted to be 2 symbol channels turned off and 12 symbol channels turned on according to the second level utilizing the state information. The symbol channels can be randomly selected to be switched on or switched off, and the method only needs to be adjusted to switch off 2 symbol channels and switch on 12 symbol channels. It can be understood that, preferably, if the symbol channel is currently 5 off and 9 on, then 3 on are randomly selected directly from the 5 off symbol channels to improve the working efficiency. The second situation is state B (symbol channel 0, symbol channel 1 are turned off, and symbol channel 2 to symbol channel 13 are turned on), then according to the second level, the current on-off state of the symbol channel is adjusted to symbol channel 0, symbol channel 1 is turned off, and symbol channel 2 to symbol channel 13 are turned on;
the third level utilizes the on-off state of the target mapped by the state information, and the same principle is carried out by the second level utilizing the state information;
and if the switch state of the target mapped by the state information at the fourth level is that the symbol channel is completely closed, all the symbol channels are closed according to the state information at the fourth level.
Further exemplary illustrations may refer to the following application examples three through seven.
In some embodiments, as shown in fig. 8, step S110 includes:
step S111: and generating the utilization state information according to the utilization rate of the unit channel of the radio frequency unit.
In some embodiments, step S111 is applied to the base station, and the baseband module is used to monitor the user terminal access amount of the radio frequency unit in real time, convert the user terminal access amount into a utilization rate of a unit channel of the radio frequency unit (the utilization rate of the unit channel is a ratio of the utilization amount of the unit channel to the total amount of the unit channel), generate the utilization state information according to the utilization rate of the unit channel of the radio frequency unit, and send the utilization state information to the radio frequency unit.
In some embodiments, the baseband module may also be used to generate the utilization state information directly according to the access amount of the user terminal, or the baseband module may be used to convert the access amount of the user terminal into the utilization number of the unit channel of the radio frequency unit, and generate the utilization state information according to the utilization number of the unit channel of the radio frequency unit.
In some embodiments, the baseband module includes a baseband processing unit and a bridge device, and the baseband processing unit is connected to the radio frequency unit through the bridge device, so that the baseband processing unit monitors the user terminal access amount of the radio frequency unit in real time, converts the user terminal access amount into the utilization rate of the unit channel of the radio frequency unit, generates the utilization state information according to the utilization rate of the unit channel of the radio frequency unit, and sends the utilization state information to the bridge device. And the bridging equipment turns on or off the data of the unit channel of the corresponding radio frequency unit according to the utilization state information. The process of turning on or off the data of the corresponding unit channel refers to the description of step S122, and is not described herein again.

If the baseband module only comprises the baseband processing unit and does not comprise the bridging device, namely the baseband processing unit is directly connected with the radio frequency unit, the baseband processing unit monitors the user terminal access amount of the radio frequency unit in real time, converts the user terminal access amount into the utilization rate of the unit channel of the radio frequency unit, generates the utilization state information according to the utilization rate of the unit channel of the radio frequency unit, and sends the utilization state information to the radio frequency unit. And the radio frequency unit receives the utilization state information of the unit channel of the radio frequency unit issued by the baseband processing unit. Please refer to the description of application example one for the method steps executed by the subsequent radio frequency unit, which is not described herein again.
In a second aspect, as shown in fig. 9, an embodiment of the present invention provides a method for controlling power of a radio frequency unit, which is applied to a baseband module. The method comprises the following steps:

Correspondingly, the radio frequency unit turns on or turns off the corresponding unit channel according to the identification information of the unit channel, or the radio frequency unit turns on or turns off the corresponding unit channel according to the information of the data of the unit channel.
Because the utilization state information of the unit channel of the radio frequency unit is generated according to the access amount of the user terminal, the switching state of the unit channel of the radio frequency unit is adjusted according to the utilization state information of the unit channel of the radio frequency unit, so that the switching state of the unit channel of the radio frequency unit is adaptively adjusted along with the access amount of the user terminal, the user experience is not influenced, and the effects of energy conservation and consumption reduction of the radio frequency unit can be achieved.

In some embodiments, after the baseband module turns on or off the data of the unit channel, the data of the unit channel is output to the radio frequency unit (if the data of the unit channel is turned off, it is equivalent to that the data output to the radio frequency unit is 0 bit). And the radio frequency unit detects the power of the received data of the unit channel, if the power is normal, the corresponding unit channel is opened according to the control instruction, and if the power is 0, the corresponding unit channel is closed according to the control instruction, so that the current switching state of the unit channel is adjusted to the target switching state.
In some embodiments, as shown in fig. 11, step S210 includes:
