【Detailed ways】

The solutions of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application.

The term "and/or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship. In addition, "many" herein means two or more than two. In addition, the term "at least one" herein means any one of a variety or any combination of at least two of the more, for example, including at least one of A, B, and C, which may mean including from A, Any one or more elements selected from the set formed by B and C.

Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a first embodiment of an energy saving method for a base station according to the present application. Specifically, the following steps may be included:

Step S11: Detect whether the user access status of the base station conforms to the preset access user status.

The base station energy saving method described in this application may be executed by a base station in a communication system, such as a 4G base station, a 5G base station, or a base station used for private network communication.

The mobile terminal can establish a communication connection with the base station, and the base station can determine its own working status according to the access status of the user (mobile terminal). Therefore, in this application, the base station can detect the access status of its own users, so as to determine whether there are users accessing the base station, the number of users accessing the base station, and so on. In this application, by detecting user access conditions, it can be determined whether the current user access conditions meet the preset conditions, and thus determine the working mode of the subsequent base station. In this embodiment, it can be judged whether the user access condition meets the preset access user condition, if yes, step S12 and step S13 can be performed; if not, step S14 and step S15 can be performed. Step S12: Determine to enter the energy saving mode.

When the base station detects that the user access condition meets the preset access user condition, the base station will determine to enter the energy-saving mode. The preset access user condition is, for example, that the base station has no access users. At this time, because the base station has no access users, the base station can selectively not send some information that does not affect user access, so as to reduce the energy consumption.

In a specific implementation scenario, the above-mentioned user access situation is specifically that the base station has no access user and the duration is longer than a preset threshold. When the base station has no access users, in order to improve the stability of the system, the base station may determine to enter the energy-saving mode only when the base station has no access users and the duration is longer than a preset threshold. The preset threshold is, for example, 10 seconds, 15 seconds, etc., and the setting of the preset threshold can be adjusted as required.

After entering the energy-saving mode, step S13 can be continued.

Step S13: When the base station is in the energy-saving mode, send part of the information in the wireless frame to be sent or not send the information in the wireless frame to be sent.

The base station is in the energy-saving mode, and when sending the wireless frame to be sent, it will send part of the information in the wireless frame to be sent or not send the information in the wireless frame to be sent. The sending by the base station of the part of the information in the radio frame to be sent may specifically be sending the information of a part of the subframes in the radio frame to be sent. For example, the base station may not send information irrelevant to the user's access to the base station, but only send information related to the user's access to the base station.

In one embodiment, the transmitting power of the base station can be reduced by adjusting the radio frequency transmitting circuit in the base station. For example, the transmit power of the base station can be reduced by adjusting the working state of the power amplifier in the base station. Specifically, after the base station enters the energy-saving mode, the power amplifier may be adjusted to the first working state, and the state of the power amplifier may be adjusted, specifically by controlling the radio frequency signal input to the power amplifier.

When the base station enters the energy-saving mode and the power amplifier is in the first working state, if the base station only sends part of the information in the wireless frame to be sent, it can control the radio frequency signal input to the power amplifier to be only the radio frequency signal carrying this part of the information, then the power The amplifier only needs to amplify this part of the radio frequency signal, thereby reducing the radio frequency signal that the power amplifier needs to amplify and process, and reducing the transmission power of the base station. If the base station does not transmit information in the wireless frame to be transmitted, no radio frequency signal is input to the power amplifier, so the power amplifier does not need to work, that is, the transmit power of the base station is 0 at this time. When it is determined to send only part of the information in the wireless frame to be sent or not to send the information in the wireless frame to be sent, by reducing the radio frequency signal that needs to be input to the power amplifier, the radio frequency signal that the power amplifier needs to be amplified is reduced, thereby reducing The transmit power of the base station.

After step S11, if it is detected that the user access situation does not meet the preset access user conditions, step S14 may be executed at this time.

Step S14: Determine to enter the normal mode.

When the base station detects that the user access situation does not meet the preset access user conditions, it can be determined that the base station enters the normal mode.

Step S15: When the base station is in the normal mode, send all the information in each radio frame to be sent.

When the base station is in the normal mode, the base station can send all information in each radio frame to be sent, and the information sent by the base station includes, for example, information related to user access and information not related to user access. Information unrelated to user access is, for example, various information sent when communicating with the user.

In one embodiment, when it is determined that the base station is in the normal mode, all information in each radio frame to be sent may be sent by adjusting a radio frequency transmitting circuit of the base station. For example, the power amplifier of the base station can be adjusted to the second working state. When the power amplifier is in the second working state, the base station sends all the transmission information in each wireless frame to be transmitted, that is, the radio frequency signal used to carry the entire wireless frame to be transmitted will be input into the power amplifier, and then amplified by the power amplifier After the transmission, users who have already connected to the base station can perform normal communication.

Referring to FIG. 2 , FIG. 2 is a second schematic flowchart of an embodiment of a method for energy saving of a base station according to the present application. This embodiment is a further extension of the "send part of the information in the wireless frame to be sent or not send the information in the wireless frame to be sent" mentioned in the above step S13, and specifically includes the following steps S131 to S133.

Step S131: Determine whether the information in the wireless frame to be sent includes the first preset sending message.

After the base station enters the energy-saving mode, it can determine which messages in the wireless frames to be sent specifically need to be sent according to the types of the wireless frames to be sent that need to be sent. Therefore, the base station can specifically determine which messages need to be sent by judging whether the information in the radio frame to be sent includes the first preset sending message. In a specific implementation manner, judging whether the information in the wireless frame to be sent includes the first preset sending message may specifically be judging whether the subframe carrying the wireless frame to be sent includes the first preset sending message.

In one embodiment, the first preset sending message is a broadcast message. Because the broadcast message involves the process of the user accessing the base station, it can be further determined which part of the information in the wireless frame to be sent needs to be sent by judging whether the wireless frame to be sent includes the broadcast message. Specifically, the broadcast message includes at least: primary synchronization signal (Primary Synchronization Signal, PSS), secondary synchronization signal (Secondary Synchronization Signal, SSS), information transmitted by physical broadcast channel (Physical broadcast channel, PBCH), system information block 1 One of (System Information Block1, SIB1) and System Information Block 2 (System Information Block2, SIB2).

If the information in the wireless frame to be sent includes the first preset sending message, execute step S132, and if the information in the wireless frame to be sent does not include the first preset sending message, execute step S133.

Step S132: Sending a second preset sending message in the wireless frame to be sent, where the second preset sending message includes at least part of the first preset sending message.

The information in the wireless frame to be sent includes the first preset sending message, which means that the message sent by the wireless frame to be sent involves the process of user accessing the base station. Therefore, the base station can send the second preset sending message in the wireless frame to be sent. A message, wherein the second preset message to send at least includes part of the first preset message to send.

In one embodiment, the second preset sending message includes at least one of a broadcast message, a cell reference signal (Cell reference signal, CRS), and a message transmitted using a physical control information indicator channel (Physical Control Format Indicator Channel, PCFICH) . Specifically, the base station sends the second preset sending message in the to-be-sent radio frame, and specifically may be sending a subframe in the to-be-sent wireless frame that includes the second preset sending message.

For example, the base station may send part of the first preset sending message, and also send one of a cell reference signal and a message using physical control information to indicate channel transmission. In a specific scenario, the wireless frame to be sent includes a message transmitted using a physical downlink control channel (PDCCH), a cell reference signal, a message transmitted using a physical control information indication channel, a primary synchronization signal and a secondary synchronization signal , the information includes the primary synchronization signal and secondary synchronization signal belonging to the first preset sending message, so the base station will send the primary synchronization signal, secondary synchronization signal, cell reference signal and use physical control information to indicate the channel transmission message, The message transmitted by using the physical downlink control channel is not sent.

The base station sends the second preset sending message, so that the terminal can receive the second preset sending message and establish a communication connection with the base station, and the base station only sends the second preset sending message, and other messages are not sent, thereby also reducing The transmission power of the base station is improved, and the energy consumption of the base station is reduced.

Step S133: Do not send the information in the wireless frame to be sent.

When the information in the wireless frame to be sent does not include the first preset sending message, it means that the information contained in the wireless frame to be sent does not involve the process of user accessing the base station, so the base station may choose not to send the wireless frame to be sent. In this way, the transmission power consumption of the base station is reduced, so as to achieve the purpose of energy saving.

In a specific implementation scenario, the wireless frame to be sent includes a message transmitted using the physical downlink control channel, a cell reference signal, and a message transmitted using the physical control information indication channel. It can be seen that the wireless frame to be sent does not contain the first A preset sending message, so the base station will not send the radio frame to be sent.

Those skilled in the art can understand that in the above method of specific implementation, the writing order of each step does not mean a strict execution order and constitutes any limitation on the implementation process. The specific execution order of each step should be based on its function and possible The inner logic is OK.

In a specific embodiment, the first working state of the power amplifier includes a low-power working state and a static working state, and the difference between the two lies in whether there is a radio frequency signal input into the power amplifier. When the information in the radio frame to be sent includes the first preset sending message, the base station will send the second preset sending message, and at this time, the working state of the power amplifier can be adjusted to a low power working state. Adjusting the working state of the power amplifier is to input the radio frequency signal used to carry the second preset sending message into the power amplifier, and use the power amplifier to process this part of the radio frequency signal. When the information in the wireless frame to be sent does not include the first preset sending message, the base station will not send the information in the wireless frame to be sent. At this time, the working state of the power amplifier can be adjusted to a static working state. The RF signal is input to the power amplifier. Therefore, when only sending part of the information in the wireless frame to be sent (the second preset sending message) or not sending the information in the wireless frame to be sent, by reducing the radio frequency signal input to the power amplifier, or by not inputting the radio frequency signal to the The power amplifier reduces the power of the power amplifier so as to reduce the transmission power of the base station.
