Energy-saving method and device

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on December 28, 2023, with application number 202311855679.8 and application name "A Energy-Saving Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of wireless communication technology, and in particular to an energy-saving method and device. Background Art

[0004] The radio frequency unit (RFU) is an essential component of a base station. When a terminal is connected to the base station, the RFU remains operational to provide network services. However, if no terminal is connected, continued operation of the RFU results in inefficient energy consumption. For fixed periods of inactivity, the base station can place the RFU in a dormant state to reduce inefficient energy consumption. For example, late at night, when there may be few or no terminals connected, the base station can place the RFU in a dormant state. During this time, the RFU cannot provide network services and cannot send or receive RF signals.

[0005] With the above-mentioned RF unit sleep mode, the base station can put some or all RF units into sleep mode, so some or all carriers corresponding to the RF units can be in shutdown mode. However, the base station cannot perceive the service load status of the carriers and lacks the function of adjusting the carrier shutdown according to the service load.

[0006] During certain periods, such as late at night and early morning, the cell managed by the base station is unloaded or lightly loaded. The radio frequency unit (RFU) remains operational, but few or no terminals are actually using these RF signals. Therefore, for the base station, the energy consumed by these RF signals is ineffective. RF signals are transmitted via carrier waves. In the frequency domain, these carrier waves can be turned off to eliminate any active carriers on the RF unit, reducing this ineffective energy consumption.

[0007] However, the aforementioned carrier-off technology only manages traffic load but fails to optimize radio frequency unit (RF) shutdown. Even if some carriers are shut down, the corresponding RF units may still have active carriers. This prevents the base station from putting these RF units into sleep mode, thus failing to reduce energy consumption. Summary of the Invention

[0055] In order to facilitate understanding of the technical solutions provided by the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained and illustrated below.

[0056] 1) Carrier is a physical concept that refers to the modulated radio electromagnetic wave that carries information. Each carrier occupies a certain range of frequencies.

[0057] 2) Cell: A cell is a basic unit in a wireless communication system that provides coverage to meet the communication needs of terminals. Each cell can correspond to one or more carriers.

[0058] 3) Frequency band refers to the frequency range of electromagnetic waves. A base station can send electromagnetic waves in one or more frequency bands, and one frequency band can correspond to one or more carriers.

[0059] The technical solutions of the embodiments of the present application can be applied to New Radio (NR) systems, Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Worldwide Interoperability for Microwave Access (WiMAX) communication systems, and fifth generation communication systems (5G) and 5G th generation, 5G), the next generation wireless communication system, no restrictions are made here.

[0060] FIG1 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in FIG1 , the communication system includes a wireless access network 100. The wireless access network 100 may include at least one network device (such as 110a and / or 110b in FIG1 ) and may also include at least one terminal device (such as at least one of 120a-120j in FIG1 ). The terminal device is connected to the access network device wirelessly, and the access network device is connected to the core network device wirelessly or by wire. Terminal devices and network devices may be connected to each other by wire or by wireless. FIG1 is only a schematic diagram, and the communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG1 .

[0061] A network device is a network-side device with wireless transceiver capabilities. A network device can be a device in a radio access network (RAN) that provides wireless communication capabilities for terminal devices, and is called a RAN device. For example, a network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. It can also be a module or unit that performs some of the functions of a base station, such as a centralized unit (CU) or a distributed unit (DU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The network device can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0062] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes implement part of the functions of the base station respectively. For example, the RAN node can be a CU, DU, CU-control plane (CP), CU-user plane (UP), or radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0063] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0064] A terminal device is a user-side device with wireless transceiver capabilities. A terminal device may also be referred to as user equipment (UE), a mobile station, a mobile terminal, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home appliance, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0065] Network devices and terminal devices can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; and in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of network devices and terminal devices.

[0066] The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile network device. To terminal devices 120j accessing the wireless access network 100 via 120i, terminal device 120i is a network device. However, to network device 110a, 120i is a terminal device, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via an interface protocol between network devices. In this case, 120i is also a network device relative to 110a. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with network device functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal device functionality.

[0067] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem that includes the network device function. The control subsystem that includes the network device function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device that includes the terminal device function. In the following, the example in which the terminal device function is performed by the terminal and the network device function is performed by the base station is described.

[0068] As shown in Figure 2, a base station consists of a radio frequency unit (RFU) and a baseband unit (BBU). The RFU primarily performs functions such as RF signal reception and transmission, baseband signal modulation and demodulation, data processing, and power amplification. The BBU provides external interfaces and performs system resource management, operation and maintenance, and environmental monitoring. The RFU and BBU are connected via optical fiber and can communicate via a fronthaul interface.

[0069] It should be noted that the baseband unit may also be referred to as a baseband module, baseband device, etc. Similarly, the radio frequency unit may also be referred to as a radio frequency module, radio frequency device, etc., which is not specifically limited in this application.

[0070] The radio frequency unit is an indispensable part of the base station. When there are terminals connected to the base station, the radio frequency unit keeps working to provide network services to the terminals. However, if there are no terminals connected to the base station, the radio frequency unit will continue to work and generate invalid energy consumption.

[0071] For fixed periods of inactivity, the base station can place the RF unit in a dormant state to reduce inefficient energy consumption. Referring to Figure 3A, during the day, when terminals are connected to the base station, the RF unit can remain operational and provide network services. Late at night, when there may be fewer or even no terminals connected, the base station can place the RF unit in a dormant state. During this time, the RF unit cannot provide network services and cannot send or receive RF signals.

[0072] With the above-mentioned RF unit sleep mode, the base station can put some or all RF units into sleep mode, so some or all carriers corresponding to the RF units can be in shutdown mode. However, the base station cannot perceive the service load status of the carriers and lacks the function of adjusting the carrier shutdown according to the service load.

[0073] The following describes how to shut down the carrier.

[0074] During certain periods, such as late at night and early morning, the cell managed by the base station is unloaded or lightly loaded. The radio frequency unit (RFU) remains operational, but few or no terminals are actually using these RF signals. Therefore, for the base station, the energy consumed by these RF signals is ineffective. RF signals are transmitted via carrier waves. In the frequency domain, these carrier waves can be turned off to eliminate any active carriers on the RF unit, reducing this ineffective energy consumption.

[0075] Referring to Figure 3B, for a fixed period of time in a multi-frequency, multi-carrier co-coverage networking scenario where the cell managed by the base station is lightly loaded or unloaded, the base station can dynamically shut down the capacity layer carrier used to absorb peak traffic and migrate users on the capacity layer carrier to the base layer carrier providing basic network coverage. When the load is high, the base station dynamically turns on the capacity layer carrier to ensure normal service.

[0076] However, the aforementioned carrier-off technology only manages traffic load but fails to optimize radio frequency unit (RF) shutdown. Even if some carriers are shut down, the corresponding RF units may still have active carriers. This prevents the base station from putting these RF units into sleep mode, thus failing to reduce energy consumption.

[0077] Referring to Figure 4, it is assumed that the base station supports frequency bands A, B, and C. It is understandable that each frequency band can correspond to one or more carriers. Among them, frequency bands A and B form a group and are controlled by the components of a single radio frequency unit. Frequency band C forms a group and is controlled by the components of a single radio frequency unit. Frequency bands A, B, and C form a group. When the carrier corresponding to frequency band A is lightly loaded or unloaded, the base station will shut down the carrier corresponding to frequency band A, such as shutting down frequency band A. However, since frequency bands A and B form a group and are controlled by the components of a single radio frequency unit, even though the base station shuts down frequency band A, frequency band B is in operation, and the components of the radio frequency unit must also be in operation, thus failing to reduce energy consumption.

[0078] In view of this, an embodiment of the present application provides an energy-saving method. In this method, the radio frequency unit can send a carrier combination and / or a frequency band combination to the baseband unit. The baseband unit can determine configuration information for energy saving based on the carrier combination and / or frequency band combination and send it to the radio frequency unit. The configuration information can indicate the carriers and / or frequency bands to be shut down. The radio frequency unit can shut down corresponding components, such as a power amplifier, based on the configuration information to achieve energy saving.

[0079] Referring to FIG5 , which is an exemplary flow chart of an energy-saving method provided in an embodiment of the present application, the method may include the following operations.

[0080] S501: The radio frequency unit sends first information to the baseband unit.

[0081] Correspondingly, the baseband unit receives the first information from the radio frequency unit.

[0082] The first information may indicate one or more carrier combinations and / or one or more frequency band combinations. It is understood that a carrier combination may include one or more carriers, and a frequency band combination may include one or more frequency bands. For example, the first information may indicate one or more carrier combinations. For another example, the first information may indicate one or more frequency band combinations. For another example, the first information may indicate one or more carrier combinations and one or more frequency band combinations. Optionally, the first information may include energy-saving strategy information.

[0083] Optionally, the embodiment shown in FIG5 may further include the following operation S500.

[0084] S500: The baseband unit sends second information to the radio frequency unit.

[0085] Correspondingly, the radio frequency unit receives the second information from the baseband unit.

[0086] The second information may be used to request, query, or obtain the first information. The baseband unit may instruct the radio frequency unit to send the first information to the baseband unit through the second information.

[0087] In one possible scenario, the first information may include identifiers of frequency bands included in one or more frequency band combinations, and / or identifiers of carriers included in one or more carrier combinations. For example, the first information may include identifiers of one or more frequency band combinations, and identifiers of frequency bands included in each frequency band combination, to indicate one or more frequency band combinations. Exemplarily, as shown in FIG4 , the first information may include group 0 and group 1, where group 0 includes band A and band B, and group 1 includes band C.

[0088] For another example, the first information may include identifiers of one or more carrier combinations and identifiers of the carriers included in each carrier combination, thereby indicating one or more carrier combinations. Exemplarily, the first information may include group 0, group 1, and group 2, where group 0 includes carrier A and carrier B, group 1 includes carrier C, and group 2 includes carrier D and carrier E.

[0089] For another example, the first information may include identifiers of one or more frequency band combinations, as well as identifiers of the frequency bands included in each frequency band combination, to indicate one or more frequency band combinations. Furthermore, the first information may include identifiers of one or more carrier combinations, as well as identifiers of the carriers included in each carrier combination, to indicate one or more carrier combinations. Repetitive details are not repeated here.

[0090] The first information can be used to determine the frequency band or carrier shutdown combination. For example, the baseband unit can determine the carrier combination and / or frequency band combination on the radio frequency unit based on the first information, thereby determining the frequency band or carrier shutdown combination. For example, the baseband unit can determine which frequency band combinations or carrier combinations need to be shut down in order to put the components on the radio frequency unit into hibernation, thereby achieving energy conservation.

[0091] Referring to Figure 4, the first information sent by the radio frequency unit to the baseband unit includes band A and band B as a group, band C as a group, and band A, band B, and band C as a group. The baseband unit can determine that if it wants to achieve the purpose of energy saving, it needs to turn off band A and band B, or turn off band C, or turn off band A, band B, and band C. That is to say, the baseband unit can determine that the shutdown combinations of the frequency bands are band A and band B as a combination, band C as a combination, and band A, band B, and band C as a combination. The baseband unit can determine which shutdown combination to use according to requirements, such as business requirements and energy saving requirements. Optionally, the baseband unit can migrate the terminal on the frequency band that needs to be shut down to other frequency bands, and instruct the radio frequency unit to shut down the corresponding frequency band. For example, assuming the baseband unit determines to use a shutoff combination of frequency bands A and B, the baseband unit can migrate or drive terminals on frequency bands A and B to frequency band C and instruct the radio frequency unit to shut down frequency bands A and B. Compared with related technologies, the technical solution of shutting down carriers only by traffic load can improve energy saving.

[0092] In another possible implementation, the first information may further include priorities corresponding to one or more frequency band combinations and / or priorities corresponding to one or more carrier combinations. For example, the first information may include one or more frequency band combinations and priorities corresponding to the one or more frequency band combinations. For another example, the first information may include one or more carrier combinations and priorities corresponding to the one or more carrier combinations. For another example, the first information may include one or more frequency band combinations, priorities of the one or more frequency band combinations, and one or more carrier combinations, priorities corresponding to the one or more carrier combinations.

[0093] In one possible scenario, the priority level can represent the priority of energy conservation. For example, a higher priority level indicates a higher priority for energy conservation and better energy conservation results, while a lower priority level indicates a lower priority for energy conservation and worse energy conservation results. Conversely, a lower priority level indicates a higher priority for energy conservation and better energy conservation results, while a higher priority level indicates a lower priority for energy conservation and worse energy conservation results.

[0094] Referring to Figure 4 , the first information sent by the RF unit to the baseband unit includes bands A and B as a group, band C as a group, and bands A, B, and C as a single group. The group consisting of bands A, B, and C has the highest priority, indicating the highest energy-saving priority and the best energy-saving effect. The group consisting of bands A and B has the second highest priority, indicating a high energy-saving priority and a good energy-saving effect. The group consisting of bands C has the lowest priority, indicating the lowest energy-saving priority and a fair energy-saving effect.

[0095] The above priorities can be used to determine frequency band or carrier shutdown combinations. For example, the baseband unit can determine the carrier combination and / or frequency band combination on the radio frequency unit, as well as the corresponding priority, based on the first information, and thus can determine the frequency band or carrier shutdown combination. For example, the baseband unit can determine which frequency band combinations or carrier combinations need to be shut down before the device on the radio frequency unit can be put into sleep mode to achieve the purpose of energy saving. In addition, the baseband unit can determine which frequency band combinations or carrier combinations need to be shut down based on the priority to achieve better energy saving effects. For example, the baseband unit can determine the carriers or frequency bands included in the shutdown combination with the highest shutdown priority. For another example, the baseband unit can determine the frequency bands included in K1 shutdown combinations with high shutdown priority. For another example, the baseband unit can determine the carriers included in K2 shutdown combinations with high shutdown priority. K1 and K2 are both integers greater than or equal to 1, and K1 and K2 can be the same or different.

[0096] Referring to Figure 4 , the first information sent by the RF unit to the baseband unit includes bands A and B as a group, band C as a group, and bands A, B, and C as a single group. The group consisting of bands A, B, and C has the highest priority, indicating the highest energy-saving priority and the best energy-saving effect. The group consisting of bands A and B has the second highest priority, indicating a high energy-saving priority and a good energy-saving effect. The group consisting of bands C has the lowest priority, indicating the lowest energy-saving priority and a fair energy-saving effect.

[0097] The baseband unit can determine that to achieve energy conservation, it is necessary to shut down frequency bands A and B, or shut down frequency band C, or shut down all of frequency bands A, B, and C. In other words, the baseband unit can determine the frequency band shutoff combinations to be: frequency bands A and B as one combination, frequency band C as another combination, and frequency bands A, B, and C as another combination. Shutting down all of frequency bands A, B, and C achieves the best energy conservation effect, shutting down both frequency bands A and B achieves a slightly lower energy conservation effect than shutting down all of frequency bands A, B, and C, and shutting down frequency band C achieves a slightly lower energy conservation effect than shutting down both frequency bands A and B.

[0098] The baseband unit can determine which frequency band combinations or carrier combinations to shut down based on priority to achieve better energy-saving effects. For example, the baseband unit can determine to shut down the carriers or frequency bands included in the shutdown combination with the highest priority. In other words, the baseband unit can determine to shut down frequency bands A, B, and C to achieve better energy-saving effects. Compared with the existing technology, the technical solution of shutting down carriers only by business load can improve energy-saving effects. And based on priority, the energy-saving method with the best effect can be determined.

[0099] In an embodiment of the present application, the baseband unit may determine a shut-down combination of carriers or frequency bands based on the first information. Optionally, the baseband unit may determine a shut-down combination of carriers or frequency bands based on the first information and the service load. For example, the baseband unit may determine a shut-down combination of carriers or frequency bands based on the first information. And determine the energy-saving effect of each shut-down combination based on the priority. The baseband unit may obtain the service load of the carrier, that is, the baseband unit may determine the load corresponding to each carrier or each frequency band, and thus may determine to shut down the carriers or frequency bands included in the shut-down combination where the carriers or frequency bands with lower loads are located.

[0100] Referring to Figure 4 , the first information sent by the RF unit to the baseband unit includes bands A and B as a group, band C as a group, and bands A, B, and C as a single group. The group consisting of bands A, B, and C has the highest priority, indicating the highest energy-saving priority and the best energy-saving effect. The group consisting of bands A and B has the second highest priority, indicating a high energy-saving priority and a good energy-saving effect. The group consisting of bands C has the lowest priority, indicating the lowest energy-saving priority and a fair energy-saving effect.

[0101] The baseband unit can determine that to achieve energy conservation, it is necessary to shut down frequency bands A and B, or shut down frequency band C, or shut down all of frequency bands A, B, and C. In other words, the baseband unit can determine the frequency band shutoff combinations to be: frequency bands A and B as one combination, frequency band C as another combination, and frequency bands A, B, and C as another combination. Shutting down all of frequency bands A, B, and C achieves the best energy conservation effect, shutting down both frequency bands A and B achieves a slightly lower energy conservation effect than shutting down all of frequency bands A, B, and C, and shutting down frequency band C achieves a slightly lower energy conservation effect than shutting down both frequency bands A and B.

[0102] In one example, the baseband unit can obtain the business load and determine that band A and band C are lightly loaded, and band B is heavily loaded. The baseband unit can determine the frequency bands that need to be shut down based on requirements, such as business requirements and energy-saving requirements. If the baseband unit shuts down band A, band B cannot be shut down because it is heavily loaded, so the purpose of energy saving cannot be achieved. Therefore, the baseband unit can determine to shut down band C. Although the energy-saving effect of shutting down band C is the lowest, considering the shutdown combination and business load, the baseband unit can determine that the energy-saving effect of shutting down band C at this time is the best. Optionally, the baseband unit can migrate the terminal on band C to band A and band B, and instruct the radio frequency unit to shut down band C.

[0103] In another example, the baseband unit can obtain the business load and determine that band A and band B are lightly loaded, and band C is heavily loaded. The baseband unit can determine the frequency bands that need to be shut down based on requirements, such as business requirements and energy-saving requirements. Since band A and band B are in the same shutdown combination, and the priority corresponding to the shutdown combination is the second highest. Taking into account the shutdown combination and the business load, the baseband unit can determine that shutting down band A and band B at this time will have the best energy-saving effect. Optionally, the baseband unit can migrate the terminals on band A and band B to band C, and instruct the radio frequency unit to shut down band A and band B.

[0104] S502: The baseband unit sends configuration information to the radio frequency unit.

[0105] Correspondingly, the radio frequency unit receives the configuration information from the baseband unit.

[0106] The configuration information may indicate that a frequency band included in at least one frequency band combination among one or more frequency band combinations is to be turned off, or the configuration information may indicate that a carrier included in at least one carrier combination among one or more carrier combinations is to be turned off.

[0107] In one possible implementation, the configuration information may instruct to shut down the frequency bands included in at least one frequency band combination among one or more frequency band combinations. For example, the configuration information may instruct to delete one or more carriers on the frequency bands included in at least one frequency band combination. For another example, the configuration information may instruct to deactivate one or more carriers on the frequency bands included in at least one frequency band combination. For another example, the configuration information may instruct to block one or more carriers on the frequency bands included in at least one frequency band combination. For another example, the configuration information may instruct to shut down one or more carriers on the frequency bands included in at least one frequency band combination. If the configuration information instructs to shut down the frequency bands included in all frequency band combinations among one or more frequency band combinations, the configuration information may instruct radio frequency hibernation.

[0108] In another possible implementation, the configuration information may instruct to shut down carriers included in at least one carrier combination in one or more carrier combinations. For example, the configuration information may instruct to delete carriers included in at least one carrier combination. For another example, the configuration information may instruct to deactivate carriers included in at least one carrier combination. For another example, the configuration information may instruct to block carriers included in at least one carrier combination. For another example, the configuration information may instruct to shut down carriers included in at least one carrier combination. If the configuration information instructs to shut down carriers included in all carrier combinations in one or more carrier combinations, the configuration information may instruct to put the radio frequency into hibernation.

[0109] Based on the method in S501, the baseband unit can determine which carrier or frequency band shutdown combination to shut down to achieve energy conservation. Therefore, the baseband unit can determine configuration information based on the determined shutdown combination. Assuming that in Figure 4, the baseband unit determines that frequency bands A and B need to be shut down, the baseband unit can instruct the radio frequency unit to shut down the carriers on frequency bands A and B included in frequency band combination 0 through configuration information.

[0110] S503: The radio frequency unit shuts down a frequency band included in at least one frequency band combination, or shuts down a carrier included in at least one carrier combination based on the configuration information.

[0111] In one possible implementation, the configuration information may indicate that the frequency bands included in at least one frequency band combination among one or more frequency band combinations should be shut down, and the radio frequency unit may shut down the frequency bands included in the at least one frequency band combination. For example, the radio frequency unit may delete one or more carriers on the frequency bands included in the at least one frequency band combination. For another example, the radio frequency unit may deactivate one or more carriers on the frequency bands included in the at least one frequency band combination. For another example, the radio frequency unit may block one or more carriers on the frequency bands included in the at least one frequency band combination. For another example, the radio frequency unit may shut down one or more carriers on the frequency bands included in the at least one frequency band combination. If the configuration information indicates that the frequency bands included in all frequency band combinations among the one or more frequency band combinations should be shut down, the radio frequency unit may enter radio frequency sleep mode.

[0112] In another possible implementation, the configuration information may indicate that the carriers included in at least one carrier combination in one or more carrier combinations should be shut down. In this case, the RF unit may shut down the carriers included in the at least one carrier combination. For example, the RF unit may delete the carriers included in the at least one carrier combination. For another example, the RF unit may deactivate the carriers included in the at least one carrier combination. For another example, the RF unit may block the carriers included in the at least one carrier combination. For another example, the RF unit may shut down the carriers included in the at least one carrier combination. If the configuration information indicates that the carriers included in all carrier combinations in the one or more carrier combinations should be shut down, the RF unit may enter RF sleep mode.

[0113] The energy-saving method provided in the embodiments of the present application can be applied to O-RAN scenarios. In O-RAN scenarios, the RF unit and the baseband unit may be from different manufacturers. Therefore, the RF unit sends the first information to the baseband unit, which enables the baseband unit to shut down the carrier or frequency band combination of the RF unit. The baseband unit can then determine which shutdown combination of the RF unit to shut down based on energy-saving requirements and service requirements, and then instruct the RF unit through configuration information. The RF unit can shut down the corresponding device, carrier, or frequency band based on the configuration information, thereby achieving the purpose of energy saving.

[0114] The operations performed by the baseband unit can be performed by the BBU, CU, DU or CU-CP. The operations of the radio frequency unit can be performed by the RRU or RU.

[0115] Exemplarily, the RRU may send the first information to the BBU. The BBU may determine the configuration information and send it to the RRU. Exemplarily, the RU may send the first information to the CU, the CU may send the first information to the DU, the DU may determine the configuration information and send it to the CU, and the CU may send the configuration information to the RU.
