Abstract
Description
Technical Field
[0001] This application relates to the field of communication technologies, and more specifically, to a method and an apparatus for power allocation.
Background Art
[0002] This application claims the priority of Chinese Patent Application No. 202210608971.9, titled "METHOD AND APPARATUS FOR POWER ALLOCATION", filed with the State Intellectual Property Office of China on May 31, 2022, which is incorporated herein by reference in its entirety.
[0003] The transmission power of channels in a communication system may be lost in some scenarios. For example, when a radio unit disables some transmission channels to reduce the system power consumption, power losses of some channels may be caused. To ensure the transmission quality of the information carried by the channels, the system may reserve a part of the power when allocating power. When the communication system needs to boost the transmission power of the information carried by the channels, the radio unit may boost the transmission power by using a reserved part of the power. However, the reserved part of the power is fixed. In some scenarios, the reserved part of the power may not meet the boosting requirements.
Summary of the Invention
[0004] This application provides a method and an apparatus for power allocation to improve the flexibility of power allocation.
[0005] According to a first aspect, a method for power allocation is provided. The method may be implemented by a control device or a chip in the control device. The method includes the following. The control device receives capability information from a radio frequency device, and the capability information indicates a correspondence between a power boost amplitude of a first channel and a power back-off amplitude of a second channel. The control device sends first indication information to the radio frequency device, and the first indication information indicates that the power boost amplitude of the first channel is a first amplitude and the power back-off amplitude of the second channel is a second amplitude, and the first amplitude and the second amplitude are determined based on the capability information and a required boost amplitude of the first channel.
[0006] In an embodiment of the present application, it may be understood that the power boost amplitude of the first channel may be the power boost amplitude of the transmission power of the information carried by the first channel. The power back-off amplitude of the second channel may be the power back-off amplitude of the transmission power of the information carried by the second channel.
[0007] Therefore, in the present application, the control device can know about the correspondence between the power boost amplitude of the first channel and the power back-off amplitude of the second channel based on the capability information. Further, based on the required boost amplitude of the first channel and the capability information, the control device can indicate the transmission power of the information carried by the first channel of the radio frequency device that should be increased only by the first amplitude, and the transmission power of the information carried by the second channel that should be reduced only by the second amplitude. In this way, the radio frequency device can boost the transmission power of the information carried by the first channel in a manner of reducing the transmission power of the information carried by the second channel, thereby improving the flexibility of power allocation.
[0008] Regarding the first aspect, in some implementations of the first aspect, the control device sends second indication information to the radio frequency device. The second indication information indicates a first bandwidth. The first bandwidth is used to carry a first channel and a second channel. The first bandwidth is determined based on the required boost amplitude and the capability information.
[0009] Optionally, the first bandwidth is smaller than the initial bandwidth. The initial bandwidth is the bandwidth initially configured by the control device to carry the first channel and the second channel.
[0010] Accordingly, in the present application, the control device may further increase the power baseline of the power spectrum corresponding to the first bandwidth in combination with a method of reducing the first bandwidth, and thus, the power boost amplitude capability of the first channel is further improved, thereby improving the reliability of transmitting the information carried by the first channel.
[0011] Regarding the first aspect, in some implementations of the first aspect, the power boost amplitude is less than or equal to the required boost amplitude.
[0012] Accordingly, in the present application, the control device may preferentially use a method of reducing the transmission power of the information carried by the second channel to boost the transmission power of the information carried by the first channel. When the power boost amplitude indicated by the capability information does not meet the required boost amplitude, the control device further boosts the transmission power of the information carried by the first channel in combination with a method of increasing the power baseline by reducing the bandwidth.
[0013] Regarding the first aspect, in some implementations of the first aspect, the control device sends request information to the radio frequency device. The request information is used to request the capability information.
[0014] Therefore, in the present application, the radio frequency device may send capability information to the control device in response to the request information, and thus, it is possible to improve the system flexibility.
[0015] Regarding the first aspect, in some implementations of the first aspect, the required boost amplitude corresponds to the amount of disabled transmission channels of the radio frequency device.
[0016] Therefore, in the present application, in the scenario where the radio frequency device disables a transmission channel, the transmission power of the information carried by the first channel is boosted to prevent the disabling of the transmission channel from affecting the quality of the information sent by the radio frequency device through the first channel, thereby improving the system reliability.
[0017] Regarding the first aspect, in some implementations of the first aspect, the first channel is a control channel and the second channel is a data channel.
[0018] Regarding the first aspect, in some implementations of the first aspect, the information carried by the first channel includes a synchronization signal block SSB.
[0019] Therefore, in the present application, reliable transmission of the SSB can be guaranteed by boosting the transmission power of the information carried by the first channel, thereby improving the reliability of system communication.
[0020] According to a second aspect, a method for power allocation is provided. The method may be implemented by a radio frequency device or a chip in the radio frequency device. The method includes the following. The radio frequency device sends capability information to a control device, and the capability information indicates a correspondence between a power boost amplitude of a first channel and a power back-off amplitude of a second channel. The radio frequency device receives first indication information from the control device, and the first indication information indicates that the power boost amplitude of the first channel is a first amplitude and the power back-off amplitude of the second channel is a second amplitude, and the first amplitude and the second amplitude are determined based on the capability information and a required boost amplitude of the first channel.
[0021] Therefore, in the present application, the control device can know about the correspondence between the power boost amplitude of the first channel and the power back-off amplitude of the second channel based on the capability information. Further, based on the required boost amplitude of the first channel and the capability information, the control device can indicate the transmission power of the information carried by the first channel of the radio frequency device that should be increased by only the first amplitude, and the transmission power of the information carried by the second channel that should be reduced by only the second amplitude. In this way, the radio frequency device boosts the transmission power of the information carried by the first channel in a manner of reducing the transmission power of the information carried by the second channel, thereby improving the flexibility of power allocation.
[0022] Regarding the second aspect, in some implementations of the second aspect, the method further includes the following. The radio frequency device sends the information carried by the first channel based on the first amplitude indicated by the first indication information, and sends the information carried by the second channel based on the second amplitude indicated by the first indication information.
[0023] Regarding the second aspect, in some implementations of the second aspect, the method further includes the following. The radio frequency device receives second indication information from the control device. The second indication information indicates a first bandwidth. The first bandwidth is used to carry a first channel and a second channel. The first bandwidth is determined based on the required boost amplitude and the capability information.
[0024] Regarding the second aspect, in some implementations of the second aspect, the method further includes the following. The radio frequency device sends the information carried by the first channel based on the first amplitude indicated by the first indication information and the first bandwidth indicated by the second indication information, and sends the information carried by the second channel based on the second amplitude indicated by the first indication information and the first bandwidth indicated by the second indication information.
[0025] Regarding the second aspect, in some implementations of the second aspect, the power boost amplitude is less than or equal to the required boost amplitude.

[0028] Regarding the second aspect, in some implementations of the second aspect, the first channel is a control channel and the second channel is a data channel.
[0029] Regarding the second aspect, in some implementations of the second aspect, the information carried by the first channel includes a synchronization signal block SSB.
[0030] According to a third aspect, a method for power allocation is provided. The method may be implemented by a control device or a chip in the control device. The method includes the following. The control device sends indication information to a radio frequency device, and the indication information indicates a first bandwidth. The first bandwidth is determined based on the required boost amplitude of a first channel, and the numerical value of the first bandwidth is smaller than an initial bandwidth value. The initial bandwidth value is the bandwidth value initially configured by the control device to carry the first channel. The radio unit sends the first channel based on the indication information.
[0031] In other words, the control device reduces the bandwidth value used to carry the first channel based on the required boost amplitude of the first channel, and the reduced bandwidth is the first bandwidth.
[0032] Therefore, in this application, the control device may determine the bandwidth used to carry the first channel in order to boost the transmission power of the information carried by the first channel. Thus, the information carried by the first channel can be reliably transmitted, thereby improving the reliability of system communication.
[0033] Regarding the third aspect, in some implementations of the third aspect, the information carried by the first channel includes a synchronization signal block SSB.
[0034] According to a fourth aspect, an apparatus for power allocation is provided. The apparatus includes a transceiver unit and a processing unit. The transceiver unit is configured to receive capability information from a radio frequency device. The capability information indicates a correspondence between a power boost amplitude of a first channel and a power back-off amplitude of a second channel. The processing unit is configured to generate first indication information. The first indication information indicates that the power boost amplitude of the first channel is a first amplitude and that the power back-off amplitude of the second channel is a second amplitude. The first amplitude and the second amplitude are determined based on the capability information and a required boost amplitude of the first channel. The transceiver unit is further configured to send the first indication information to the radio frequency device.
[0035] Therefore, in the present application, the control device can know about the correspondence between the power boost amplitude of the first channel and the power back-off amplitude of the second channel based on the capability information. Further, based on the required boost amplitude of the first channel and the capability information, the control device can indicate the transmission power of the information carried by the first channel of the radio frequency device that should be increased by only the first amplitude, and the transmission power of the information carried by the second channel that should be reduced by only the second amplitude. In this way, the radio frequency device can boost the transmission power of the information carried by the first channel in a manner of reducing the transmission power of the information carried by the second channel, thereby improving the flexibility of power allocation.

The first amplitude and the second amplitude are determined based on the capability information and the required boost amplitude of the first channel.
[0043] Therefore, in the present application, the control device can know the correspondence between the power boost amplitude of the first channel and the power back-off amplitude of the second channel based on the capability information. Further, based on the required boost amplitude of the first channel and the capability information, the control device can indicate the transmission power of the information carried by the first channel of the radio frequency device that should be increased by only the first amplitude, and the transmission power of the information carried by the second channel that should be reduced by only the second amplitude. In this way, the radio frequency device can boost the transmission power of the information carried by the first channel in a manner of reducing the transmission power of the information carried by the second channel, thereby improving the flexibility of power allocation.

[0070] Hereinafter, the technical solutions of the present application will be described with reference to the accompanying drawings.
[0071] The technical solutions in the embodiments of this application can be applied to various communication systems, such as long term evolution (LTE) systems, frequency division duplex (FDD) systems, time division duplex (TDD) systems, 5th generation (5G) systems or new radio (NR), 6th generation (6G) systems, or future communication systems. The 5G mobile communication system in this application includes a non-standalone (NSA) 5G mobile communication system or a standalone (SA) 5G mobile communication system. The communication system can alternatively be a public land mobile network (PLMN), a device-to-device (D2D) communication system, a machine to machine (M2M) communication system, an Internet of things (IoT) communication system, a vehicle to everything (V2X) communication system, an unmanned aerial vehicle (UAV) communication system, or another communication system.
[0072] The network architectures and service scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions in the embodiments of this application, but do not constitute a limitation on the technical solutions provided in the embodiments of this application. Those skilled in the art may know that the technical solutions provided in the embodiments of this application are also applicable to similar technical problems as the network architecture evolves and new service scenarios emerge.
[0073] For ease of understanding the embodiments of this application, the application scenarios of the embodiments of this application will be first described in detail with reference to FIG. 1.
[0074] FIG. 1 is a schematic diagram of the structure of a communication system to which an embodiment of the present application is applicable. Devices that may be used in the communication system will be described first.
[0075] Radio Unit (RU) 110: The radio unit 110 may implement functions such as intermediate frequency processing, radio frequency processing, and signal multiplexing. For example, the radio unit 110 may be a remote radio unit (RRU), an active antenna unit (AAU), or another network element or communication device having the ability of intermediate frequency signal processing, radio frequency signal processing, or intermediate radio frequency signal processing.
[0076] Baseband Unit 120: The baseband unit 120 may implement baseband signal processing functions. For example, the baseband unit 120 may include at least one of a central unit (CU), a distributed unit (DU), or another network element or communication device having baseband signal processing capabilities. For example, the baseband unit may also be referred to as a BBU (baseband unit, BBU).
[0077] The communication interface between the baseband unit 120 and the radio unit 110 may be a fronthaul interface. For example, the interface may be a common public radio interface (CPRI), an enhanced CPRI (eCPRI), or another interface defined in the future for connecting the baseband unit 120 and the radio unit 110.
[0078] Figure 2 is a schematic diagram of the structure of a system having a plurality of architectures to which the embodiments of the present application are applicable. An example in which the system includes two radio units is used for explanation. The system includes a baseband unit 210, a radio unit 220, and a radio unit 230. The baseband unit 210 may be the baseband unit 120 of FIG. 1, and the radio units 220 and 230 may be the radio unit 110 of FIG. 1. The present application is described by using an example in which the system includes a direct connection system and a cascade system. For the direct connection system, refer to section (a) of FIG. 2. The baseband unit 210 is separately and directly connected to the radio unit 220 and the radio unit 230. The baseband unit 210 separately performs direct communication through the interface of the radio unit 220 and the interface of the radio unit 230. For the cascade system, refer to section (b) of FIG. 2. The baseband unit 210 is directly connected to the radio unit 220. The radio unit 220 is directly connected to the radio unit 230. The baseband unit 210 directly communicates with the radio unit 220. The baseband unit 210 can communicate with the radio unit 230 by using the radio unit 220. The interface between the radio unit 220 and the radio unit 230 may also be a fronthaul interface.
[0079] In the above, only the system in some architectures to which this embodiment of the present application is applicable is described. This embodiment of the present application may be further applicable to a system in another architecture in which a radio unit can communicate with a baseband unit. This is not particularly limited in the present application.
[0080] Figure 3 is a schematic flowchart of a method 300 according to an embodiment of the present application.
[0081] S310: The radio frequency device sends capability information to the control device.
[0082] Correspondingly, the control device receives the capability information from the radio frequency device.
[0083] The radio frequency device may be the radio unit 110 in FIG. 1, and the control device may be the baseband unit 120 in FIG. 1.
[0084] The capability information indicates the correspondence between the power boost amplitude of the first channel and the power back-off amplitude of the second channel.
[0085] It may be understood that the power boost amplitude of the first channel may be the power boost amplitude of the transmission power of the information carried by the first channel. The power back-off amplitude of the second channel may be the power back-off amplitude of the transmission power of the information carried by the second channel. In this embodiment of the present application, the power for sending the first channel, the power for sending the information carried by the first channel, the transmission power (or transmission power) of the first channel, and the transmission power (or transmission power) of the information carried by the first channel may represent the same meaning. Correspondingly, the power for sending the second channel, the power for sending the information carried by the second channel, the transmission power (or transmission power) of the second channel, and the transmission power (or transmission power) of the information carried by the second channel may represent the same meaning. Details will not be described below.
[0086] The power boost amplitude may represent the multiple by which the power of the first channel is boosted. The multiple may be represented in decibels (dB) (1 dB = 10 lg(A / B), where A / B represents the multiple. For example, A / B is the ratio of the power value after boost (A) to the power value before boost (B)). The power back-off amplitude may represent the multiple by which the power of the second channel is reduced. This multiple may also be represented in decibels. In the present application, boosting the power may also be understood as increasing the power and focusing the power. Reducing the power may also be understood as power back-off.
[0087] In addition, in this embodiment of the present application, the information carried by the first channel and the information carried by the second channel can be the information transmitted by the wireless unit by using the antenna of the wireless unit. The above information carried by the channel may include data or signaling. For example, the information carried by the first channel and the information carried by the second channel can be the information sent by the wireless unit to the terminal device.
[0088] The first channel is a channel with boosted power, and the second channel is a channel with reduced power. Based on this technical solution, the power of the second channel is reduced so that the power boost of the first channel does not exceed the limit of the total power of the first channel and the second channel. For example, the total power of the first channel and the second channel may be limited by components such as a power amplifier in the wireless unit. If the total power of the first channel and the second channel is greater than a specific value, there is a risk of burning out the power amplifier. Therefore, in the power allocation process, the sum of the power of the first channel and the power of the second channel is below a specific value. When the power of the first channel is boosted, the power of the second channel can be reduced so that the sum of the power of the first channel after boosting and the power of the second channel after back-off is still smaller than a specific value. That is, regardless of how the power of the first channel or the power of the second channel changes, the sum of the power of the first channel and the power of the second channel of the first channel is below a specific value. It may be understood that this specific value can be set based on the actual situation, and this is not limited in the present application.
[0089] In a possible implementation, the first channel is a control channel, and the second channel is a data channel.
[0090] The information carried by the control channel includes control signaling, and the information carried by the data channel includes data. The control signaling is the signaling necessary for the operation of the communication system. Thus, in some scenarios, the radio frequency device may boost the power of the control channel to ensure a secure and reliable transmission of the control signaling.
[0091] For example, the control channel can be a physical downlink control channel (PDCCH). The data channel can be a physical downlink shared channel (PDSCH).
[0092] Optionally, the information carried by the first channel includes a synchronization signal block (SSB), which may alternatively refer to a synchronization signal / physical broadcast channel block (SS / PBCH Block).
[0093] The SSB mainly includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH). The SSB includes a two-dimensional region of four orthogonal frequency division multiplexing (OFDM) symbols in the time domain and 20 resource blocks (RBs) in the frequency domain. The terminal device may complete cell synchronization and coarse symbol-level timing synchronization by demodulating the PSS and SSS, and complete system frame-level timing synchronization by demodulating the master information block (MIB) information carried in the PBCH, and obtain the related configuration information of the system information block (SIB1), which is sometimes also called the remaining minimum system information (RMSI). Therefore, the power of the first channel carrying the SSB can be boosted to ensure that the coverage area of the SSB can meet the service requirements.
[0094] For example, the capability information may include a mapping relationship between the numerical value of the power boost amplitude and the numerical value of the power back-off amplitude. For example, the capability information includes a table corresponding to the numerical value of the power boost amplitude and the numerical value of the power back-off amplitude. Alternatively, the capability information includes a functional formula corresponding to the power boost amplitude and the power back-off amplitude. The corresponding explanatory forms are not limited in this embodiment of the present application.
[0095] The radio frequency device may be understood to be able to obtain correspondence in a plurality of ways. For example, the radio frequency device may obtain the correspondence between the power boost amplitude and the power back-off amplitude by means of simulation calculation, or the radio frequency device may obtain the correspondence by means of analyzing historical data.
[0096] In addition, the radio frequency device may actively send capability information to the control device, or may send the capability information to the control device based on a request from the control device. In this case, optionally, before step S310, the control device may send request information to the radio frequency device. The request information is used to request capability information. Further, the radio frequency device may send the capability information to the control device in response to the request information.
[0097] S320: The control device sends first indication information to the radio frequency device.
[0098] Correspondingly, the radio frequency device receives the first indication information from the control device.
[0099] The first indication information indicates that the power boost amplitude of the first channel is the first amplitude and that the power back-off amplitude of the second channel is the second amplitude.
[0100] For example, the first indication information may directly indicate that the power boost amplitude of the first channel is the first amplitude and that the power back-off amplitude of the second channel is the second amplitude. For example, the first indication information may include an information field indicating the power boost amplitude of the first channel and an information field indicating the power back-off amplitude of the second channel. These two information fields respectively include the numerical value of the first amplitude and the numerical value of the second amplitude. Alternatively, the first indication information may indirectly indicate that the power boost amplitude of the first channel is the first amplitude and that the power back-off amplitude of the second channel is the second amplitude. For example, the first indication information may indicate that the numerical value of the first amplitude is the maximum value of the power boost amplitude of the first channel. Further, the radio frequency device may determine the numerical value of the first amplitude. Then, the numerical value of the second amplitude is determined based on the numerical value of the first amplitude and the correspondence between the power boost amplitude of the first channel and the power back-off amplitude of the second channel. Alternatively, the first indication information may be a combination of a direct indication and an indirect indication, indicating that the power boost amplitude of the first channel is the first amplitude and that the power back-off amplitude of the second channel is the second amplitude. For example, the first indication information indicates an information field of the power boost amplitude of the first channel. The information field includes data of the first amplitude. In addition, the first indication information indirectly indicates that the radio frequency device determines the numerical value of the second amplitude based on the numerical value of the first amplitude and the correspondence. In a specific implementation process, the first indication information performs indications in a plurality of forms. This is not particularly limited in this application.
[0101] In a possible implementation, the control device may determine the first amplitude and the second amplitude based on the capability information and the required boost amplitude of the first channel, and may send the capability information based on the determined first amplitude and the determined second amplitude.
[0102] Hereinafter, the required boost amplitude of the first channel will be described.
[0103] To meet the service requirements, the control device can boost the power of the first channel to a specific power. The amplitude to which the power is boosted to the specific power is the required boost amplitude. The control device can determine the required boost amplitude by analyzing the service or operating state. It may be understood that the required boost amplitude is set based on the service requirements.
[0104] For example, the required boost amplitude corresponds to the amount of disabled transmission channels of the radio frequency device. In some scenarios, the radio frequency device may disable some radio frequency channels to reduce the energy consumption. However, since the disabling of the radio frequency channels may cause a transmission power loss of the first channel, in order to ensure that the transmission quality of the first channel meets the requirements, the control device may determine the required boost amplitude based on the amount of disabled transmission channels of the radio frequency device. The control device may pre-configure the correspondence between the amount of disabled radio frequency channels and the required boost amplitude. Alternatively, the control device may determine the required boost amplitude based on the amount of transmission channels by using a pre-set algorithm. This is not particularly limited in the present application.
[0105] It may also be understood that the power boost requirements may also be related to the system interference intensity, service load, etc. For example, when implementing power allocation, the control device may determine the required boost amplitude of the first channel based on the current operating environment of the system. For example, when the operating state of the system's transmission antenna is poor and the interference intensity is high, the control device can determine the required boost amplitude in order to ensure that the coverage area for transmitting the first channel meets the operating requirements.
[0106] The control device can obtain the required boost amplitude of the first channel. For example, the above control device determines the required boost amplitude based on the amount of disabled transmission channels of the radio frequency device and obtains the power boost amplitude of the first channel. For example, the control device information determines at least one power boost amplitude of the first channel based on a table corresponding to the power boost amplitude of the first channel and the power back-off amplitude of the second channel included in the capability information. For example, when the required boost amplitude can be a value of at least one power boost amplitude, the control device can take the first amplitude as the required boost amplitude. Alternatively, the required boost amplitude may be a value of two power boost amplitudes among at least one power boost amplitude. In this case, the control device may take the larger value of the two power boost amplitudes as the first amplitude. In addition, the control device may determine the value of the second amplitude based on the first amplitude and the corresponding table. Hereinafter, by using examples, the method by which the control device determines the first amplitude and the second amplitude based on the capability information will be described.
[0107] For example, when the power boost amplitude of the first channel is 1 dB, correspondingly, the power back-off amplitude of the second channel is 1.5 dB. When the power boost amplitude of the first channel is 2 dB, correspondingly, the power back-off amplitude of the second channel is 3 dB. When the required boost amplitude of the first channel is 1 dB, the control device may determine that the first amplitude is 1 dB and the second amplitude is 1.5 dB, and determine the first indication information. The first indication information indicates that the first amplitude is 1 dB and the second amplitude is 1.5 dB. When the required boost amplitude of the first channel is 1.5 dB, the control device may round up the first amplitude to 2 dB and the second amplitude to 1.5 dB, and determine the first indication information. The first indication information indicates that the first amplitude is 2 dB and the second amplitude is 1.5 dB. The description is provided with reference to FIG. 4. FIG. 4 is a schematic diagram of power allocation implemented by the control device in a manner of reducing the power of the second channel and boosting the power of the first channel. The initial power baseline is the power baseline before the power of the first channel is boosted and before the power of the second channel is reduced. The control device boosts the power of the first channel by the first amplitude and reduces the power of the second channel by the second amplitude based on the initial power baseline. In addition, it should be noted that the schematic diagram of FIG. 4 is only used to explain the power allocation method and is not drawn to a certain scale. The numerical values of the initial power baseline, frequency, first amplitude, and second amplitude are not limited.
[0108] Therefore, based on the above description, the control device determines a power allocation method based on the capability information sent by the radio frequency device and the required boost amplitude of the first channel, whereby the system can be reliably executed by boosting the power of the first channel and reducing the power of the second channel.
[0109] When the control device performs power allocation, in addition to the above method of boosting the power of the first channel and reducing the power of the second channel, it should be noted that the control device may alternatively adjust the transmission power of the first channel and the transmission power of the second channel in combination with a method of adjusting the bandwidth. Hereinafter, a method by which the control device adjusts the bandwidth will be described with reference to step S330 and step S340.
[0110] Optionally, S330: The control device determines a first bandwidth. The first bandwidth is used to carry the first channel and the second channel.
[0111] In other words, the first bandwidth includes the bandwidth for carrying the first channel and the second channel.
[0112] It should be noted that the first bandwidth is related to the power spectrum of the channel, and the power spectrum describes the correspondence between frequency and power. For example, the power spectrum may describe the power of the signals sent by each of the carriers corresponding to the first bandwidth. The area covered by the power spectrum curve is numerically equal to the total power of the signal. When the power is limited, the spectral density of the power spectrum can be increased by reducing the first bandwidth, whereby a power boost is performed on the channel based on the basic power, or the basic power in the power back-off is boosted. The basic power is also sometimes called the power baseline. Further, the radio frequency device may perform a power boost based on the increased power baseline of the first channel, whereby the transmission power of the first channel can be further improved. In other words, the transmission power of the first channel is the product of the power baseline and the multiple of the boost. The radio frequency device may determine the transmission power of the first channel by determining the power baseline by using the first bandwidth and determining the multiple of the boost by using the first amplitude indicated by the first indication information.
[0113] It should be understood that the first bandwidth can further carry another channel. For example, when the control device performs resource scheduling by using a resource block (RB) as granularity, the first bandwidth may be the bandwidth corresponding to the RB, and the first bandwidth may carry the channel carried in the RB.
[0114] In a possible implementation, the control device may determine the first bandwidth, the first amplitude, and the second amplitude based on the capability information and the required boost amplitude. For example, when allocating power, the control device may set the ratio of each of the two methods in which the power of the first channel is boosted by reducing the power of the second channel and the power baseline of the first channel is increased by reducing the first bandwidth. For example, when the required boost amplitude is 2 dB, the control device may increase the power by 1 dB in the method of reducing the first bandwidth and increase the power by 1 dB in the method of reducing the power of the second channel. This is not limited in this application.
[0115] In another possible implementation, when the power boost amplitude is smaller than the required boost amplitude, the control device may determine the first bandwidth, the first amplitude, and the second amplitude based on the capability information and the required boost amplitude. In other words, the control device may preferentially use the method of reducing the power of the second channel to boost the power of the first channel. When the power boost amplitude indicated by the capability information is smaller than the required boost amplitude, the control device further boosts the power of the first channel in combination with the method of increasing the power baseline by reducing the bandwidth. For example, when the required boost amplitude is 2 dB and the capability information indicates that the maximum value of the power boost amplitude of the first channel is 1.5 dB, the control device may increase the power by 1.5 dB in the method of reducing the power of the second channel and increase the power by 0.5 dB in the method of reducing the first bandwidth.
[0116] The description is provided with reference to FIG. 5. FIG. 5 is a schematic diagram of the control device performing power allocation in a manner that combines two methods. The control device increases the initial power baseline to an adjusted baseline by reducing the bandwidths used to carry the first channel and the second channel. In addition, the control device determines that the first channel increases by a first amplitude and the second channel decreases by a second amplitude based on the adjusted power baseline. In addition, it should be noted that the schematic diagram of FIG. 5 is only used to explain the power allocation method and is not drawn to scale. The numerical values of the initial power baseline, the adjusted power baseline, the frequency, the first amplitude, and the second amplitude are not limited.
[0117] Optionally, S340: The control device sends second indication information to the radio frequency device.
[0118] Correspondingly, the radio frequency device receives the second indication information from the control device.
[0119] The second indication information indicates the first bandwidth.
[0120] In a possible implementation, the second indication information includes a bandwidth value of the first bandwidth or a change amplitude of the first bandwidth, for example, a reduction amplitude of the first bandwidth. Further, the radio frequency device may determine that the initial power baselines of the first channel and the second channel are boosted to an adjusted power baseline based on the bandwidth value or the reduction amplitude. Therefore, the radio frequency device may increase the power of the first channel by the first amplitude and reduce the power of the second channel by the second amplitude based on the adjusted power baseline.
[0121] In another possible implementation, the second indication information includes power spectrum parameters corresponding to the first channel and the second channel. Further, the radio frequency device may determine a first bandwidth used to carry the first channel and the second channel based on the power spectrum parameters, as well as an adjusted power baseline corresponding to the first bandwidth. Accordingly, the radio frequency device may increase the power of the first channel by a first amplitude and reduce the power of the second channel by a second amplitude based on the adjusted power baseline.
[0122] Optionally, the power spectrum parameters include clipping parameters. Further, the radio frequency device may reduce the peak-to-average ratio of the power spectrum based on the clipping parameters, improve the reliability of power allocation, and avoid signal non-linearity distortion and spectral regrowth caused by bandwidth adjustment. The peak-to-average ratio is the ratio of the peak power to the average power or the root mean square of the power spectrum curve. If the peak-to-average ratio is greater than a specific value, it means that by transmitting a signal by the radio frequency device based on the power spectrum, internal components such as a power amplifier may be overheated, and as a result, there is a risk of burnout in the power amplifier.
[0123] It should be noted that the control device may send the first indication information and the second indication information to the radio frequency device separately, or combine the first indication information and the second indication information into one piece of information and send this information to the radio frequency device. This is not particularly limited in this application.
[0124] Optionally, S350: The radio frequency device sends the information carried by the first channel and the information carried by the second channel based on the first indication information.
[0125] When the radio frequency device further receives second indication information from the control device, the radio frequency device may send the information carried by the first channel and send the information carried by the second channel based on the first indication information and the second indication information.
[0126] For example, the radio frequency device determines the transmission power of the first channel and the transmission power of the second channel based on the first indication information or the first indication information and the second indication information, and by using the antenna of the radio frequency device, the information carried by the first channel and the information carried by the second channel can be sent.
[0127] It should be noted that in the above example, the power boost amplitude, the power back-off amplitude, the required boost amplitude, the first amplitude, and the second amplitude are described in the form of decibels, but this form is not particularly limited in this application. For example, the embodiments provided in this application may also be implemented in the form of multiples, specific power values, etc.
[0128] Therefore, in this application, the control device can dynamically determine the power boost amplitude of the first channel and the power back-off amplitude of the second channel based on the capability information sent by the radio frequency device, thereby improving the flexibility of power allocation.
[0129] In the above, it is explained how the control device determines the power boost amplitude of the first channel and the power back-off amplitude of the second channel based on the capability information sent by the radio frequency device, and optionally further improves the transmission power of the first channel by adjusting the bandwidth used to carry the first channel and the second channel. The embodiments of this application further provide a method. In this method, the first bandwidth can be directly adjusted based on the requirements for the boost amplitude. This will be explained below.
[0130] FIG. 6 is a schematic flowchart of another method for power allocation according to an embodiment of the present application.
[0131] S610: The control device sends indication information to the radio frequency device.
[0132] Correspondingly, the radio frequency device receives the indication information from the control device.
[0133] The indication information indicates a first bandwidth. The first bandwidth is determined based on the required boost amplitude of the first channel.
[0134] For example, the control device may determine the first bandwidth based on the required boost amplitude of the first channel. The first bandwidth is used to carry the first channel. The numerical value of the first bandwidth is smaller than the initial bandwidth value of the initial bandwidth. For example, the initial bandwidth value may be the bandwidth value initially configured by the control device to carry the initial bandwidth of the first channel.
[0135] Optionally, the information carried by the first channel includes SSB.
[0136] For the description of the first channel and the required boost amplitude, refer to the description of FIG. 4. For the sake of brevity, it will not be described in detail again in this specification.
[0137] The control device may boost the power of the first channel by reducing the bandwidth.
[0138] In a possible implementation, the control device may pre-configure the correspondence between the first bandwidth and the power boost amplitude of the first channel, for example, the mapping relationship between the reduced amplitude of the first bandwidth and the power boost amplitude of the first channel. Further, the control device may determine the first bandwidth based on the required boost amplitude and the correspondence. In another possible implementation, the control device may determine the first bandwidth based on the required boost amplitude by using a pre-set algorithm. The specific implementation is not limited in this application.
[0139] In a possible implementation, the indication information includes the bandwidth value of the first bandwidth or the reduced amplitude of the first bandwidth.
[0140] In another possible implementation, the indication information includes the power spectrum parameter corresponding to the first channel. Optionally, the power spectrum parameter may further include a clipping parameter.
[0141] S620: The radio frequency device sends the information carried by the first channel based on the indication information.
[0142] For example, the radio frequency device may determine the transmission power of the first channel based on the indication information and send the information carried by the first channel by using the antenna of the radio frequency device. For example, the radio frequency device may send the information carried to the terminal device by the first channel.
[0143] When the indication information includes the bandwidth value of the first bandwidth or the reduced amplitude of the first bandwidth, the radio frequency device may determine that the initial power baseline of the first channel is increased to the adjusted power baseline based on the bandwidth value or the reduced amplitude. The initial power baseline is the power baseline of the power spectrum before the first bandwidth is reduced.
[0144] When the indication information includes the power spectrum parameters corresponding to the first channel, the radio frequency device may determine a first bandwidth used to carry the first channel and an adjusted power baseline corresponding to the first bandwidth based on the power spectrum parameters. When the power spectrum parameters include clipping parameters, the radio frequency device may reduce the peak-to-average ratio of the power spectrum based on the clipping parameters to avoid signal non-linear distortion and spectrum regrowth caused by bandwidth adjustment, thereby improving the reliability of power allocation.
[0145] It may be understood that the radio frequency device may determine the power boost amplitude of the first channel based on the indication information. The power boost amplitude is the boost amplitude of the adjusted power baseline compared to the initial power baseline. Further, the radio frequency device may determine the transmission power of the first channel based on the indication information and send the information carried by the first channel by using the antenna of the radio frequency device.
[0146] Therefore, in this application, the control device may determine the bandwidth used to carry the first channel to boost the transmission power of the first channel, so that the first channel can be reliably transmitted, thereby improving the reliability of system communication.
[0147] FIG. 7 and FIG. 8 are schematic diagrams of the structures of possible devices according to embodiments of this application. These devices may be configured to implement the functions of the control device and the radio frequency device in the above method embodiments. Therefore, it is also possible to achieve the beneficial effects of the above method embodiments. In the embodiments of this application, the device may be a control device and a radio frequency device, or a module (such as a chip) used in the control device and the radio frequency device.
[0148] As shown in FIG. 7, apparatus 700 includes a processing unit 710 and a transceiver unit 720. Apparatus 700 is configured to implement the functions of the control device or the radio frequency device in the method embodiment shown in FIG. 4. Alternatively, apparatus 700 may include a module configured to implement any function or operation of the control device or the radio frequency device in the method embodiment shown in FIG. 4. The module may be implemented fully or partially by using software, hardware, firmware, or any combination thereof.
[0149] When apparatus 700 is configured to implement the functions of the control device in the method embodiment shown in FIG. 3, transceiver unit 720 is configured to receive capability information from the radio frequency device. The capability information indicates a correspondence between the power boost amplitude of the first channel and the power back-off amplitude of the second channel. Processing unit 710 is configured to generate first indication information. The first indication information indicates that the power boost amplitude of the first channel is the first amplitude and that the power back-off amplitude of the second channel is the second amplitude. The first amplitude and the second amplitude are determined based on the capability information and the required boost amplitude of the first channel. Transceiver unit 720 is further configured to send the first indication information to the radio frequency device.
[0150] Therefore, in the present application, the control device can know the correspondence between the power boost amplitude of the first channel and the power back-off amplitude of the second channel based on the capability information. Further, based on the required boost amplitude of the first channel and the capability information, the control device can indicate the transmission power of the information carried by the first channel of the radio frequency device that should be increased by only the first amplitude, and the transmission power of the information carried by the second channel that should be reduced by only the second amplitude. In this way, the radio frequency device can boost the transmission power of the information carried by the first channel in a manner of reducing the transmission power of the information carried by the second channel, thereby improving the flexibility of power allocation.
[0151] For a more detailed description of the processing unit 710 and the transceiver unit 720, please directly refer to the relevant description in the method embodiment shown in FIG. 3. Details will not be described again herein.

The first amplitude and the second amplitude are determined based on the capability information and the required boost amplitude of the first channel.
[0153] Therefore, in the present application, the control device can know the correspondence between the power boost amplitude of the first channel and the power back-off amplitude of the second channel based on the capability information. Further, based on the required boost amplitude of the first channel and the capability information, the control device can indicate the transmission power of the information carried by the first channel of the radio frequency device that should be increased by only the first amplitude, and the transmission power of the information carried by the second channel that should be reduced by only the second amplitude. In this way, the radio frequency device can boost the transmission power of the information carried by the first channel in a manner of reducing the transmission power of the information carried by the second channel, thereby improving the flexibility of power allocation.
[0154] For a more detailed description of the processing unit 710 and the transceiver unit 720, please directly refer to the relevant description in the method embodiment shown in FIG. 3. Details will not be described again herein.
[0155] When the device 700 is configured to implement the functions of the control device in the method embodiment shown in FIG. 6, the processing unit 710 generates indication information. The indication information indicates a first bandwidth. The first bandwidth is determined based on the required boost amplitude of the first channel. The numerical value of the first bandwidth is smaller than the initial bandwidth value. The initial bandwidth value is the bandwidth value initially configured by the control device for carrying the first channel. The transceiver unit 720 is configured to send the indication information to the radio frequency device. The transceiver unit 720 is further configured to send the first channel based on the indication information.
[0156] For a more detailed description of the processing unit 710 and the transceiver unit 720, please directly refer to the relevant description in the method embodiment shown in FIG. 6. Details will not be described again herein.
