Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to an energy-saving method and device. Background Art

[0002] The radio frequency unit is an essential part of a base station. When there are access terminals in the base station, the radio frequency unit can provide network services for the terminals by remaining operational. However, if there are no access terminals in the base station, continuing to keep the radio frequency unit operational will result in ineffective energy consumption. For scenarios with no traffic during fixed time periods, the base station can put the radio frequency unit into a sleep state to reduce ineffective energy consumption. For example, at midnight, since there may be few or no access terminals, the base station can put the radio frequency unit into a sleep state. At this time, the radio frequency unit cannot provide network services and cannot send or receive radio frequency signals.

[0003] In the above-mentioned method of putting the radio frequency unit into a sleep state, the base station can put some or all of the radio frequency units into a sleep state. Therefore, some or all of the carriers corresponding to the radio frequency units can be in an off state. However, the base station cannot sense the traffic load status of the carriers and lacks the function of adjusting carrier shutdown according to the traffic load.

[0004] During certain periods, such as late at night or early in the morning, the cells managed by the base station are in an idle or lightly loaded state, and the radio frequency units are still operational. However, in reality, none or only a few terminals are using these radio frequency signals. Therefore, for the base station, the energy consumption generated by this part of the radio frequency signals is ineffective energy consumption. Radio frequency signals are transmitted through carriers. Then, in the frequency domain, these carriers that transmit radio frequency signals can be directly turned off so that there are no operational carriers on the radio frequency unit, thereby reducing this part of the ineffective energy consumption.

[0005] However, the above-mentioned carrier shutdown technology can only achieve control and adjustment of the traffic load and cannot obtain the optimal shutdown method for the radio frequency unit. In the above-mentioned carrier shutdown technology, although some carriers may be turned off, there are still operational carriers under the radio frequency unit corresponding to this carrier, resulting in the base station being unable to put this radio frequency unit into a sleep state and thus unable to reduce energy consumption. Summary of the Invention

[0053] To facilitate the understanding of the technical solutions provided by the embodiments of the present application, the following explains and illustrates the technical terms involved in the embodiments of the present application.

[0054] 1) Carrier: A physical concept, referring to a modulated radio electromagnetic wave carrying information. Each carrier occupies a certain range of frequencies.

[0055] 2) Cell: In a wireless communication system, it is the basic unit that provides coverage to meet the communication needs of terminals. Each cell can correspond to one or more carriers.

[0056] 3) Frequency band: Refers to the frequency range of electromagnetic waves. A base station can send electromagnetic waves within one or more frequency bands, and one frequency band can correspond to one or more carriers.

[0057] 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), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, fifth-generation communication systems (5 th generation, 5G), next-generation wireless communication systems such as 6G, etc., without limitation here.

[0058] Figure 1It is a schematic diagram of the architecture of the communication system 1000 to which the embodiments of the present application are applied. As Figure 1 shown, the communication system includes a radio access network 100. Among them, the radio access network 100 may include at least one network device (such as Figure 1 110a and / or 110b in), and may also include at least one terminal device (such as Figure 1 at least one of 120a-120j in). 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 wiredly. The terminal devices can be connected to each other, and the network devices can be connected to each other, either wiredly or wirelessly. Figure 1 This is just a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not drawn in Figure 1 .

[0059] A network device is a network-side device with wireless transceiver capabilities. The network device can be a device in a radio access network (RAN) that provides wireless communication capabilities for terminal devices, referred to as a RAN device. For example, the network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next generation NodeB in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it can also be a module or unit that completes some functions of the base station. For example, it can be a central unit (CU) or a distributed unit (DU). Here, the CU 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 some or all of the functions of the physical layer. For specific descriptions of the above various protocol layers, reference can be made to the relevant technical specifications of the 3rd generation partnership project (3GPP). The network device can be a macro base station (such as Figure 1 110a in Figure 1 ), or a micro base station or an indoor station (such as 110b in Figure 1 ), or a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the network device.

[0060] In another possible scenario, multiple RAN nodes cooperate to assist a terminal in achieving wireless access, and different RAN nodes respectively implement partial functions of a base station. For example, the RAN node can be a CU, a DU, a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately set, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0061] In different systems, the CU (or CU-CP and CU-UP), the DU, or the 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, the CU can also be called an O-CU (open CU), the DU can also be called an O-DU, the CU-CP can also be called an O-CU-CP, the CU-UP can also be called an O-CU-UP, and the RU can also be called an O-RU. For the convenience of description, in this application, the CU, CU-CP, CU-UP, DU, and RU are used as examples for description. Any one of the 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.

[0062] A terminal device is a user-side device with wireless transceiver functions. The terminal device can also be referred to as a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal device can be widely applied to 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, remote medical treatment, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, etc. The terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver functions, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. Embodiments of the present application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0063] The network device and the terminal device can be fixed in position or movable. The network device and the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites in the air. Embodiments of the present application do not limit the application scenarios of the network device and the terminal device.

[0064] The roles of the network device and the terminal device can be relative. For example, Figure 1 the helicopter or drone 120i in [figure reference] can be configured as a mobile network device. For the terminal devices 120j that access the radio access network 100 through 120i, the terminal device 120i is a network device; but for the network device 110a, 120i is a terminal device, that is, the communication between 110a and 120i is through the radio air interface protocol. Of course, the communication between 110a and 120i can also be through the interface protocol between network devices. At this time, relative to 110a, 120i is also a network device. Therefore, the network device and the terminal device can both be uniformly referred to as communication devices. Figure 1 110a and 110b in [figure reference] can be referred to as communication devices with network device functions. Figure 1 120a - 120j in [figure reference] can be referred to as communication devices with terminal device functions.

[0065] In an embodiment of the present application, the functions of the network device can also be performed by a module (such as a chip) in the network device, or by a control subsystem including the functions of the network device. The control subsystem including the functions of the network device can be a control center in the above application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal device can also be performed by a module (such as a chip or a modem) in the terminal device, or by a device including the functions of the terminal device. In the following, an example is described in which the functions of the terminal device are performed by the terminal, and the functions of the network device are performed by the base station.

[0066] Referring to Figure 2 , the base station may include a radio frequency unit and a baseband unit. The radio frequency unit mainly completes functions such as receiving and transmitting radio frequency signals, modulating and demodulating baseband signals, data processing, and power amplification. The baseband unit provides an external interface and completes functions such as system resource management, operation and maintenance, and environmental monitoring. The radio frequency unit and the baseband unit are connected by optical fibers and can communicate through a fronthaul interface.

[0067] It should be noted that the baseband unit can also be referred to as a baseband module, a baseband device, etc. Similarly, the radio frequency unit can also be referred to as a radio frequency module, a radio frequency device, etc., and the present application does not make specific limitations.

[0068] The radio frequency unit is an essential part of the base station. When there are access terminals in the base station, the radio frequency unit can keep working to provide network services for the terminals. However, if there are no access terminals in the base station, continuing to keep the radio frequency unit working will result in ineffective energy consumption.

[0069] For the scenario of no service during a fixed period, the base station can put the radio frequency unit into a sleep state to reduce ineffective energy consumption. Referring to Figure 3A , when there are access terminals in the base station during the day, the radio frequency unit can keep working to provide network services for the terminals. At night, since there may be fewer or even no access terminals, the base station can put the radio frequency unit into a sleep state. At this time, the radio frequency unit cannot provide network services, and the radio frequency unit cannot send and receive radio frequency signals.

[0070] For the above method of putting the radio frequency unit into a sleep state, the base station can put some or all of the radio frequency units into a sleep state. Therefore, some or all of the carriers corresponding to the radio frequency units can be in an off state, but the base station cannot sense the service load state of the carriers and lacks the function of adjusting the carrier shutdown according to the service load.

[0071] The following introduces the method of carrier shutdown.

[0072] During certain periods, such as late at night or early in the morning, the cells managed by the base station are in an idle or lightly loaded state. The radio frequency (RF) units are still in an operating state, but actually there are no or only very few terminals using these RF signals. Therefore, for the base station, the energy consumption generated by this part of the RF signals is ineffective energy consumption. The RF signals are sent through carriers. Then, in the frequency domain, these carriers that send RF signals can be directly turned off so that there are no operating carriers on the RF units, thereby reducing this part of the ineffective energy consumption.

[0073] Refer to Figure 3B , for a fixed period and in a multi-frequency and multi-carrier co-coverage networking scenario where the cells managed by the base station are in a lightly loaded or idle state, the base station can dynamically turn off the capacity layer carriers used to provide capacity absorption during the peak service period, and migrate the users under the capacity layer carriers to the basic layer carriers used to provide network basic coverage. When the load is high, the base station dynamically turns on the capacity layer carriers to ensure the normal operation of the service.

[0074] However, the above carrier shutdown technology can only control and adjust the service load, but cannot obtain the optimal shutdown method for the RF units. In the above carrier shutdown technology, although some carriers may be turned off, there are still operating carriers under the RF units corresponding to these carriers, resulting in the base station being unable to put the RF units into a sleep state, thus unable to reduce energy consumption.

[0075] Refer to Figure 4 , assume that the base station supports frequency band A, frequency band B, and frequency band C. It can be understood that each frequency band can correspond to one or more carriers. Among them, frequency band A and frequency band B form a group and are controlled by the devices of one RF unit, frequency band C forms a group and is controlled by the devices of one RF unit, and frequency band A, frequency band B, and frequency band C form a group. When the carriers corresponding to frequency band A are in a lightly loaded or idle state, the base station will turn off the carriers corresponding to frequency band A, such as turning off frequency band A. However, since frequency band A and frequency band B form a group and are controlled by the devices of one RF unit. Therefore, although the base station turns off frequency band A, frequency band B is in an operating state, so the devices of this RF unit also need to be in an operating state, and thus energy consumption cannot be reduced.

[0076] In view of this, the embodiments of the present application provide an energy-saving method. In this method, the RF unit can send carrier combinations and / or frequency band combinations to the baseband unit. The baseband unit can determine the configuration information for energy saving according to the carrier combinations and / or frequency band combinations, and send it to the RF unit. Among them, the configuration information can indicate the carriers to be turned off and / or the frequency bands to be turned off. The RF unit can turn off the corresponding devices, such as power amplifiers, etc., according to this configuration information to achieve the purpose of energy saving.

[0077] Refer to Figure 5 , which is an exemplary flowchart of an energy-saving method provided by the embodiments of the present application, and may include the following operations.

[0078] S501: The radio frequency unit sends the first information to the baseband unit.

[0079] Correspondingly, the baseband unit receives the first information from the radio frequency unit.

[0080] Wherein, the first information may indicate one or more carrier combinations and / or one or more frequency band combinations. It can be understood that one carrier combination may include one or more carriers, and one frequency band combination may include one or more frequency bands. For example, the first information may indicate one or more carrier combinations. Again, for example, the first information may indicate one or more frequency band combinations. Again, for example, the first information may indicate one or more carrier combinations and one or more frequency band combinations. Optionally, the first information may be energy saving strategy information.

[0081] Optionally, Figure 5 The embodiments shown may further include the following operation S500.

[0082] S500: The baseband unit sends the second information to the radio frequency unit.

[0083] Correspondingly, the radio frequency unit receives the second information from the baseband unit.

[0084] Wherein, the second information may be used to request or query or obtain the first information. The baseband unit may, through the second information, instruct the radio frequency unit to send the first information to the baseband unit.

[0085] In a possible case, the first information may include the identifiers of the frequency bands included in one or more frequency band combinations, and / or the identifiers of the carriers included in one or more carrier combinations. For example, the first information may include the identifiers of one or more frequency band combinations, and the identifiers of the frequency bands included in each frequency band combination, to implement indicating one or more frequency band combinations. Exemplarily, as Figure 4 shown, the first information may include combination (group) 0 and combination 1, and combination 0 includes frequency band A and frequency band B, and combination 1 includes frequency band C.

[0086] Again, for example, the first information may include the identifiers of one or more carrier combinations, and the identifiers of the carriers included in each carrier combination, to implement indicating one or more carrier combinations. Exemplarily, the first information may include combination (group) 0, combination 1 and combination 2, and combination 0 includes carrier A and carrier B, combination 1 includes carrier C, and combination 2 includes carrier D and carrier E.

[0087] For another example, the first information may include the identification of one or more frequency band combinations and the identification of the frequency bands included in each frequency band combination, so as to indicate one or more frequency band combinations. And the first information may include the identification of one or more carrier combinations and the identification of the carriers included in each carrier combination, so as to indicate one or more carrier combinations. The repeated parts will not be elaborated here.

[0088] The above-mentioned 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, so as to determine the frequency band or carrier shutdown combination. For example, the baseband unit can determine which frequency band combinations or carrier combinations to shut down in order to put the devices on the radio frequency unit into sleep mode for energy saving purposes.

[0089] Refer to Figure 4 , the first information sent by the radio frequency unit to the baseband unit includes that frequency band A and frequency band B are in one group, frequency band C is in one group, and frequency band A, frequency band B and frequency band C are in one group. The baseband unit can determine that if it wants to achieve the purpose of energy saving, it needs to shut down frequency band A and frequency band B, or shut down frequency band C, or shut down frequency band A, frequency band B and frequency band C. That is to say, the baseband unit can determine that the shutdown combinations of frequency bands are that frequency band A and frequency band B are in one combination, frequency band C is in one combination, and frequency band A, frequency band B and frequency band C are in one combination. The baseband unit can determine which shutdown combination to use according to requirements, such as service requirements and energy saving requirements. Optionally, the baseband unit can migrate the terminals on the frequency bands to be shut down to other frequency bands and instruct the radio frequency unit to shut down the corresponding frequency bands. For example, assuming that the baseband unit determines to use the shutdown combination of frequency band A and frequency band B, the baseband unit can migrate or drive the terminals on frequency band A and frequency band B to frequency band C and instruct the radio frequency unit to shut down frequency band A and frequency band B. Compared with the prior art, the technical solution of shutting down carriers only according to service load can improve the energy saving effect.

[0090] In another possible implementation, the first information may further include the priority corresponding to one or more frequency band combinations and / or the priority corresponding to one or more carrier combinations. For example, the first information may include one or more frequency band combinations and the priority corresponding to the one or more frequency band combinations. For another example, the first information may include one or more carrier combinations and the priority corresponding to the one or more carrier combinations. For another example, the first information may include one or more frequency band combinations, the priority of the one or more frequency band combinations, one or more carrier combinations, and the priority corresponding to the one or more carrier combinations.

[0091] In a possible scenario, the priority can represent the priority of energy conservation. For example, the higher the priority, the higher the priority of energy conservation, and the better the energy conservation effect; the lower the priority, the lower the priority of energy conservation, and the worse the energy conservation effect. Conversely, the lower the priority, the higher the priority of energy conservation, and the better the energy conservation effect; the higher the priority, the lower the priority of energy conservation, and the worse the energy conservation effect.

[0092] Refer to Figure 4 , the first information sent by the radio frequency unit to the baseband unit includes that frequency band A and frequency band B are in one group, frequency band C is in one group, and frequency band A, frequency band B, and frequency band C are in one group. Among them, the group corresponding to frequency band A, frequency band B, and frequency band C has the highest priority, so it can represent the highest priority of energy conservation and the best energy conservation effect. The group corresponding to frequency band A and frequency band B has the second highest priority, so it can represent a relatively high priority of energy conservation and a relatively good energy conservation effect. The group corresponding to frequency band C has the lowest priority, so it can represent the lowest priority of energy conservation and a general energy conservation effect.

[0093] The above priority 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, as well as the corresponding priority, so as to determine the frequency band or carrier shutdown combination. For example, the baseband unit can determine which frequency band combinations or carrier combinations to turn off in order to put the devices on the radio frequency unit into sleep mode to achieve the purpose of energy conservation. And, the baseband unit can determine based on the priority which frequency band combinations or carrier combinations to turn off to achieve a better energy conservation effect. For example, the baseband unit can determine to turn off the carriers or frequency bands included in the shutdown combination with the highest priority. Another example is that the baseband unit can determine the frequency bands included in K1 shutdown combinations with high priority. Another example is that the baseband unit can determine the carriers included in K2 shutdown combinations with high priority. Both K1 and K2 are integers greater than or equal to 1, and K1 and K2 can be the same or different.

[0094] Refer to Figure 4 , the first information sent by the radio frequency unit to the baseband unit includes that frequency band A and frequency band B are in one group, frequency band C is in one group, and frequency band A, frequency band B, and frequency band C are in one group. Among them, the group corresponding to frequency band A, frequency band B, and frequency band C has the highest priority, so it can represent the highest priority of energy conservation and the best energy conservation effect. The group corresponding to frequency band A and frequency band B has the second highest priority, so it can represent a relatively high priority of energy conservation and a relatively good energy conservation effect. The group corresponding to frequency band C has the lowest priority, so it can represent the lowest priority of energy conservation and a general energy conservation effect.

[0095] The baseband unit can determine that if energy saving is desired, then frequency band A and frequency band B need to be turned off, or frequency band C needs to be turned off, or frequency bands A, B, and C need to be turned off all together. That is to say, the baseband unit can determine that the combinations of turned-off frequency bands are: frequency bands A and B as one combination, frequency band C as one combination, and frequency bands A, B, and C as one combination. Among them, turning off frequency bands A, B, and C all together has the best energy-saving effect. Turning off frequency bands A and B has a worse energy-saving effect than turning off frequency bands A, B, and C all together. Turning off frequency band C has a worse energy-saving effect than turning off frequency bands A and B.

[0096] The baseband unit can determine, based on the priority, which combinations of frequency bands or carriers to turn off to achieve a better energy-saving effect. For example, the baseband unit can determine the carriers or frequency bands included in the turned-off combination with the highest turn-off priority, that is, the baseband unit can determine that turning off frequency bands A, B, and C can achieve a better energy-saving effect. Compared with the prior art in which only the carriers are turned off based on the service load, this can improve the energy-saving effect. And based on the priority, an energy-saving method with a better effect can be determined.

[0097] In the embodiments of the present application, the baseband unit can determine the turned-off combination of carriers or frequency bands based on the first information. Optionally, the baseband unit can determine the turned-off combination of carriers or frequency bands based on the first information and the service load. For example, the baseband unit can determine the turned-off combination of carriers or frequency bands according to the first information. And according to the priority, determine the energy-saving effect of each turned-off combination. The baseband unit can obtain the service load of the carriers, that is to say, the baseband unit can determine the level of the load corresponding to each carrier or each frequency band, so as to determine to turn off the carriers or frequency bands included in the turned-off combination where the carriers or frequency bands with a lower load are located.

[0098] Refer to Figure 4 , the first information sent by the radio frequency unit to the baseband unit includes: frequency bands A and B as one group, frequency band C as one group, and frequency bands A, B, and C as one group. Among them, the group corresponding to frequency bands A, B, and C has the highest priority, so it can represent the highest energy-saving priority and the best energy-saving effect. The group corresponding to frequency bands A and B has the second highest priority, so it can represent a relatively high energy-saving priority and a relatively good energy-saving effect. The group corresponding to frequency band C has the lowest priority, so it can represent the lowest energy-saving priority and a general energy-saving effect.

[0099] The baseband unit can determine that if it wants to achieve the purpose of energy saving, it is necessary to turn off frequency band A and frequency band B, or turn off frequency band C, or turn off frequency bands A, B, and C. That is to say, the baseband unit can determine that the frequency band turn-off combinations are frequency bands A and B as one combination, frequency band C as one combination, and frequency bands A, B, and C as one combination. Among them, turning off frequency bands A, B, and C has the best energy-saving effect, turning off frequency bands A and B has a worse energy-saving effect than turning off frequency bands A, B, and C, and turning off frequency band C has a worse energy-saving effect than turning off frequency bands A and B.

[0100] In one example, the baseband unit can obtain the service load, determine that frequency bands A and C are lightly loaded, and frequency band B is heavily loaded. The baseband unit can determine the frequency bands to be turned off according to requirements, such as service requirements and energy-saving requirements. If the baseband unit turns off frequency band A, since frequency band B is heavily loaded and cannot be turned off, the purpose of energy saving cannot be achieved. Therefore, the baseband unit can determine to turn off frequency band C. Although the energy-saving effect of turning off frequency band C is the lowest, considering the turn-off combination and the service load situation, the baseband unit can determine that the energy-saving effect of turning off frequency band C is the best at this time. Optionally, the baseband unit can migrate the terminals on frequency band C to frequency bands A and B and instruct the radio frequency unit to turn off frequency band C.

[0101] In another example, the baseband unit can obtain the service load, determine that frequency bands A and B are lightly loaded, and frequency band C is heavily loaded. The baseband unit can determine the frequency bands to be turned off according to requirements, such as service requirements and energy-saving requirements. Since frequency bands A and B are in the same turn-off combination and the priority corresponding to this turn-off combination is the second highest. Considering the turn-off combination and the service load situation, the baseband unit can determine that the energy-saving effect of turning off frequency bands A and B is the best at this time. Optionally, the baseband unit can migrate the terminals on frequency bands A and B to frequency band C and instruct the radio frequency unit to turn off frequency bands A and B.

[0102] S502: The baseband unit sends configuration information to the radio frequency unit.

[0103] Correspondingly, the radio frequency unit receives the configuration information from the baseband unit.

[0104] Among them, the configuration information can indicate turning off at least one frequency band included in one or more frequency band combinations, or the configuration information can indicate turning off at least one carrier included in one or more carrier combinations.

[0105] In a possible implementation, the configuration information may indicate to turn off the frequency bands included in at least one of one or more frequency band combinations. For example, the configuration information may indicate 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 indicate 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 indicate 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 indicate to turn off one or more carriers on the frequency bands included in at least one frequency band combination. If the configuration information indicates to turn off the frequency bands included in all of one or more frequency band combinations, the configuration information may indicate radio frequency sleep.

[0106] In another possible implementation, the configuration information may indicate to turn off the carriers included in at least one of one or more carrier combinations. For example, the configuration information may indicate to delete the carriers included in at least one carrier combination. For another example, the configuration information may indicate to deactivate the carriers included in at least one carrier combination. For another example, the configuration information may indicate to block the carriers included in at least one carrier combination. For another example, the configuration information may indicate to turn off the carriers included in at least one carrier combination. If the configuration information indicates to turn off the carriers included in all of one or more carrier combinations, the configuration information may indicate radio frequency sleep.

[0107] Based on the method in S501, the baseband unit can determine which combination of carriers or frequency bands to turn off to achieve the purpose of energy saving. Therefore, the baseband unit can determine the configuration information based on the determined turn-off combination. Suppose Figure 4 in which the baseband unit determines that it is necessary to turn off frequency band A and frequency band B, then the baseband unit can indicate through the configuration information to the radio frequency unit to turn off the carriers on frequency band A and frequency band B included in frequency band combination 0.

[0108] S503: The radio frequency unit turns off the frequency bands included in at least one frequency band combination or turns off the carriers included in at least one carrier combination based on the configuration information.

[0109] In a possible implementation, the configuration information may indicate to turn off the frequency bands included in at least one of one or more frequency band combinations, and then the radio frequency unit may turn off the frequency bands included in at least one frequency band combination. For example, the radio frequency unit may delete one or more carriers on the frequency bands included in 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 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 at least one frequency band combination. For another example, the radio frequency unit may turn off one or more carriers on the frequency bands included in at least one frequency band combination. If the configuration information indicates to turn off the frequency bands included in all of the one or more frequency band combinations, the radio frequency unit may perform radio frequency sleep.

[0110] In another possible implementation, the configuration information may indicate to turn off the carriers included in at least one of one or more carrier combinations, and then the radio frequency unit may turn off the carriers included in at least one carrier combination. For example, the radio frequency unit may delete the carriers included in at least one carrier combination. For another example, the radio frequency unit may deactivate the carriers included in at least one carrier combination. For another example, the radio frequency unit may block the carriers included in at least one carrier combination. For another example, the radio frequency unit may turn off the carriers included in at least one carrier combination. If the configuration information indicates to turn off the carriers included in all of the one or more carrier combinations, the radio frequency unit may perform radio frequency sleep.

[0111] The energy-saving method provided in the embodiments of this application can be applied to the O-RAN scenario. In the O-RAN scenario, the radio frequency unit and the baseband unit may be from different vendors. Therefore, when the radio frequency unit sends the first information to the baseband unit, the baseband unit can know the turn-off combinations of the carriers or frequency bands of the radio frequency unit. Then, the baseband unit can determine which turn-off combination of the radio frequency unit to turn off according to the energy-saving requirements and service requirements, and then indicate it to the radio frequency unit through the configuration information. The radio frequency unit can turn off the corresponding devices, carriers or frequency bands according to the configuration information, so as to achieve the purpose of energy saving.
