Description

Technical Field

[0001] This application relates to the field of communication technologies, and more specifically, to baseband processing methods and apparatuses.

Background Art

[0002] This application claims priority to Chinese Patent Application No. 202210542972.8, titled "BASEBAND PROCESSING METHOD AND APPARATUS", filed with the China National Intellectual Property Administration on May 18, 2022, the entire content of which is incorporated herein by reference.

[0003] During the processing of baseband signals, the baseband unit and the radio unit in the access network device can process the baseband signals by sequentially executing a plurality of baseband processing functions based on a pre-set allocation pattern. In this case, the baseband processing functions executed by the baseband unit and the baseband processing functions executed by the radio unit are fixed. However, for example, since the baseband unit and the radio unit have different manufacturing technologies, hardware structures, or operating environments, the overall system power consumption brought about by different allocation patterns may be different during the processing of baseband signals, and the pre-set allocation pattern may be a pattern with high power consumption among a plurality of allocation patterns. Therefore, there is an urgent need for baseband processing methods and apparatuses for reducing system power consumption.

[0058] FIG. 1 is a diagram of the structure of a communication system to which the embodiments of the present application are applicable. The devices that may be included in this communication system will be described first.

[0059] Radio Unit (RU) 110: The radio unit 110 may perform functions such as intermediate frequency processing, radio frequency processing, and duplexing of signals. 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.

For example, when the scheduling unit 130 and the baseband unit 120 are integrally deployed, the scheduling unit 130 may communicate with the baseband unit 120 through an internal interface or communicate with the radio unit 110 through an interface. When the scheduling unit 130 and the radio unit 110 are integrally deployed, the scheduling unit 130 may communicate with the radio unit 110 through an internal interface or communicate with the baseband unit 120 through an interface. When the scheduling unit 130, the radio unit 110, and the baseband unit 120 are separately deployed, the scheduling unit 130 may communicate with the baseband unit 120 through an interface with the baseband unit 120 and communicate with the radio unit 110 through an interface with the radio unit 110, or the scheduling unit 130 may communicate directly with the baseband unit 120 and communicate with the radio unit 110 through the baseband unit 120. This is not particularly limited in this application.

[0064] The distributed base station may include at least one baseband unit and at least one radio unit. Hereinafter, with reference to FIG. 2, a system having a plurality of architectures to which the baseband unit and the radio unit are applicable will be described.

[0065] FIG. 2 is a 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 this system includes two radio units is used for description. This 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 in FIG. 1, and the radio units 220 and 230 may be the radio units 110 in FIG. 1, respectively. In the present application, an example in which this system includes a direct connection system and a cascade system is used for description. Regarding the direct connection system, refer to (a) in FIG. 2. The baseband unit 210 is directly connected to the radio unit 220 and the radio unit 230 separately. The baseband unit 210 performs direct communication separately through the interface of the radio unit 220 and the interface of the radio unit 230.

[0066] The above only describes a system having several architectures to which this embodiment of the present application is applicable.

This is not particularly limited in the present application.

[0067] Figure 3 is a schematic flowchart of baseband signal processing to which the embodiments of the present application are applicable.

[0068] Refer to Figure 3. In the downlink direction, the baseband signal can be processed in the order of encoding, rate matching, scrambling, modulation, layer mapping, pre-coding, resource element mapping, digital beamforming, inverse fast Fourier transformation (IFFT), cyclic prefix addition, analog beamforming, and digital to analog conversion. Correspondingly, in the uplink direction, the baseband signal is processed in the order of analog beamforming, analog to digital conversion, fast Fourier transformation (FFT), cyclic prefix removal, digital beamforming, resource element demapping, channel estimation, equalization, demodulation, descrambling, rate de-matching, and decoding.

[0069] In this embodiment of the present application, it should be noted that the baseband processing function can be any one of the aforementioned processing functions, or the baseband processing function can be a combined function of the plurality of aforementioned processing functions. For example, FFT and cyclic prefix removal can be regarded as one baseband processing function. The aforementioned baseband processing function can be executed by a baseband unit or can be executed by a radio unit. For example, in the downlink direction, the baseband unit sequentially executes processing of encoding, rate matching, scrambling, modulation, layer mapping, precoding, and resource element mapping for the baseband signal, and then the radio unit sequentially executes processing of digital beamforming, IFFT, cyclic prefix addition, analog beamforming, and digital / analog conversion for the signal processed by the baseband unit. In addition, the baseband unit and the radio unit can have the ability to execute the same baseband processing function. The baseband processing function shown in FIG. 3 is used as an example, and this embodiment of the present application is applicable to another procedure or a procedure of a baseband processing function defined in the future as an alternative.

[0071] In the following embodiments, the radio frequency device can be the radio unit 110 in FIG. 1, the first control device can be the baseband unit 120 in FIG. 1, and the first device can be the scheduling unit 130 in FIG. 1. When the first device, the first control device, and the radio frequency device are separately arranged, the first device, the first control device, and the radio frequency device can execute information transmission through an external interface. Hereinafter, the case where the first device, the first control device, and the radio frequency device are separately arranged is used as an example for description. This method can include the following steps.

[0072] S410: The radio frequency device transmits the first function information and the first power consumption information to the first device.

[0073] Correspondingly, the first device receives the first function information and the first power consumption information from the radio frequency device.

[0074] The first function information indicates at least one first baseband processing function supported by the radio frequency device. The at least one first baseband processing function may include one or more of the baseband processing functions shown in FIG. 3.

[0075] In a possible implementation, the first function information includes an identifier of at least one first baseband processing function supported by the radio frequency device. The identifier of the at least one first baseband processing function identifies the at least one first baseband processing function. The first device may know the baseband processing function supported by the radio frequency device based on the identifier of the first baseband processing function.

[0076] In another possible implementation, the first function information includes operation mode information. The operation mode information indicates at least one first operation mode supported by the radio frequency device. The first operation mode is an operation mode used when the radio frequency device executes one or more of the at least one first baseband processing functions. For example, the first function information includes identifiers of at least one first operation mode such as the first operation mode #1 (e.g., performing digital / analog conversion and analog beamforming), the first operation mode #2 (e.g., performing analog beamforming), and the first operation mode #3 (e.g., not performing a baseband processing function).

[0077] Specifically, the first device can pre-set the mapping relationship between the identifier of the first operation mode and the identifier of the baseband processing function. The identifier of one operation mode can correspond to some or all of the identifiers of the first baseband processing functions. For example, if the first operation mode is the operation mode used when the radio frequency device performs digital / analog conversion and analog beamforming, the mapping relationship includes the correspondence between the identifier of the first operation mode and the identifier of digital / analog conversion and the identifier of analog beamforming. Thereby, the first device can determine the baseband processing function supported by the radio frequency device based on the identifier of the first operation mode and the mapping relationship.

[0078] Optionally, the first function information may further include processing capability information corresponding to each of the first baseband processing functions. For example, the first function information further includes at least one of the information such as the number of users supported when the radio frequency device executes each of the first baseband processing functions, the number of data streams or service streams supported when the radio frequency device executes each of the first baseband processing functions, and the number of resource blocks supported when the radio frequency device executes each of the first baseband processing functions.

[0079] The number of users supported when the radio frequency device executes the baseband processing function can be the maximum value of the number of users that can be scheduled when the radio frequency device executes the baseband processing function. The number of data streams or service streams supported when the radio frequency device executes the baseband processing function can be the maximum value of the number of data streams or service streams supported when the radio frequency device executes the baseband processing function. The number of resource blocks supported when the radio frequency device executes the baseband processing function can be the maximum value of the number of resource blocks (RB) that can be scheduled when the radio frequency device executes the baseband processing function. The first device allocates the baseband processing function based on the function information, so that the baseband processing function allocated to the radio frequency device is within the capabilities of the radio frequency device, further improving the reliability of the system baseband processing.

[0080] Optionally, the first function information further includes bandwidth information, and the bandwidth information indicates the bandwidth supported by the radio frequency device.

[0081] The bandwidth can be the bandwidth of the interface between the radio frequency device and the first control device.

[0082] For example, the first function information may include a bandwidth value. Alternatively, the first function information may include parameter values such as the speed or throughput of the interface, so that the first device knows the bandwidth supported by the radio frequency device based on the parameter values, enabling the first device to determine that the radio frequency device can meet the bandwidth requirements and improving the reliability of the system baseband processing.

[0083] The first power consumption information indicates the power consumption for implementing each of at least one first baseband processing function by a radio frequency device.

[0084] The first power consumption information may include power consumption values for implementing respective first baseband processing functions by a radio frequency device. For example, the power consumption value for performing digital / analog conversion by a radio frequency device is 10 watts (W), and the power consumption value for performing analog beamforming is 20 W.

[0085] Alternatively, the first power consumption information may include power consumption levels for implementing respective first baseband processing functions by a radio frequency device. For example, the power consumption level for performing digital / analog conversion by a radio frequency device is the first power consumption level, and the power consumption level for performing analog beamforming is the second power consumption level. For example, the power consumption corresponding to the first power consumption level is the highest among the power consumptions for implementing a plurality of first baseband processing functions during the processing of a baseband signal. Similarly, the second power consumption level is the lowest among the power consumptions for implementing a plurality of first baseband processing functions. The power consumption level may be classified based on a predetermined algorithm by a radio frequency device and based on the power consumption value.

[0086] Correspondingly, when the first function information includes operation mode information, the first device may determine the power consumption corresponding to the first operation mode based on the operation mode information.

[0087] For example, the power consumption corresponding to the first operation mode is the sum of the power consumptions corresponding to the first baseband processing functions executed in the first operation mode. The first device determines one or more first baseband processing functions executed in the first operation mode based on the identifier of the first operation mode and determines the power consumption corresponding to the first operation mode.

[0088] The first power consumption information may include power consumption values for each first baseband processing function implemented by the radio frequency device, whereby the first device can obtain the power consumption corresponding to the first operating mode based on the power consumption value corresponding to the baseband processing function.

[0089] Alternatively, the first power consumption information may include power consumption values for each first operating mode implemented by the radio frequency device. For example, the power consumption corresponding to the first operating mode #1 is 30W, the power consumption corresponding to the first operating mode #2 is 20W, and the power consumption corresponding to the first operating mode #3 is 0W.

[0090] Alternatively, the first power consumption information may include the power consumption level for each first operating mode implemented by the radio frequency device, or other information capable of indicating the power consumption corresponding to the first operating mode. This is not particularly limited in the present application.

[0091] S420: The first control device transmits the second function information and the second power consumption information to the first device.

[0092] Correspondingly, the first device receives the second function information and the second power consumption information from the first control device.

[0093] The second function information indicates at least one second baseband processing function supported by the first control device.

[0094] The second power consumption information indicates the power consumption for implementing each of at least one second baseband processing function by the first control device.

[0095] The second function information indicates at least one second baseband processing function supported by the first control device. The at least one second baseband processing function may include one or more of the baseband processing functions shown in FIG. 3.

[0096] In a possible implementation, the second function information includes an identifier of at least one second baseband processing function supported by the first control device. The identifier of the at least one second baseband processing function identifies the at least one second baseband processing function. The first device may know the baseband processing functions supported by the first control device based on the identifier of the second baseband processing function.

[0097] In another possible implementation, the second function information includes operation mode information. The operation mode information indicates at least one second operation mode supported by the first control device. The second operation mode is an operation mode used when the second control device executes one or more of the at least one second baseband processing functions.

[0098] Optionally, the first function information may further include processing capacity information corresponding to each second baseband processing function. For example, the second function information further includes at least one of the information on the number of users supported when the first control device executes each second baseband processing function, the number of data streams or service streams supported when the first control device executes each second baseband processing function, and the number of resource blocks supported when the first control device executes each second baseband processing function.

[0099] The indication formats of the second function information and the second power consumption information may be the same as the indication formats in the description of the first function information and the first power consumption information in step S410. For the sake of brevity, the details will not be described here again.

[0100] In a possible implementation, the first device may be connected to a plurality of control devices. For example, the first device is separately connected to a first control device and a second control device. The first device may select a control device from the plurality of control devices and execute baseband processing. In this case, method 400 may further include step S430.

[0101] Optionally, in S430, the second control device transmits third function information and third power consumption information to the first device. Correspondingly, the first device receives the third function information and the third power consumption information from the second control device.

[0102] The third function information indicates at least one third baseband processing function supported by the second control device. The third power consumption information indicates the power consumption for implementing each of at least one third baseband processing function by the second control device.

[0103] The description regarding the third function information and the third power consumption information is similar to the description regarding the first function information and the first power consumption information in step S410. For the sake of brevity, the details will not be described here again.

[0104] Note that the radio frequency device, the first control device, and the second control device may support the same baseband processing function. For example, all of the radio frequency device, the first control device, and the second control device may support analog beamforming. However, the corresponding power consumption for executing the same baseband processing function by the radio frequency device, the first control device, and the second control device may be different. For example, the power consumption for executing analog beamforming by the radio frequency device to process data is 20W, the power consumption for executing analog beamforming by the first control device to process the same data is 30W, and the power consumption for executing analog beamforming by the second control device to process the same data is 40W.

[0105] The N required baseband processing functions may be baseband processing functions sequentially executed by the radio frequency device and the control device (the first control device or the second control device) during the processing of the baseband signal. The baseband processing functions shown in FIG. 3 may be examples of the N required baseband processing functions. The first device may know the required baseband processing functions based on preconfigured information, or the first device may know the required baseband processing functions by dynamically obtaining service information. In this case, step S440 may be further executed in method 400.

[0106] Optionally, in S440, the first device obtains service information.

[0107] For example, the first control device may predict a future service load, generate service information, and transmit the service information to the first device. The first device may determine the N required baseband processing functions sequentially executed to process the service based on the service information, whereby the first device may allocate the N required baseband processing functions to the radio frequency device and the control device (the first control device or the second control device) for processing.

[0108] Optionally, the service information may further include requirement information corresponding to one or more specific required baseband processing functions executed by the radio frequency device and / or requirement information corresponding to one or more specific required baseband processing functions executed by the control device. For example, the requirement information indicates at least one of information such as the requirement for the number of users when the radio frequency device executes one or more specific required baseband processing functions, the requirement for the number of streams when the radio frequency device executes one or more specific required baseband processing functions, or the requirement for the number of resource blocks when the radio frequency device executes one or more specific required baseband processing functions. In this way, based on the requirement information and the processing capability information of the radio frequency device, the first device may determine whether the requirements indicated by the requirement information can be satisfied when the radio frequency device executes one or more specific required baseband processing functions.

[0109] It can be understood that this step may be executed after steps S410 to S430, or may be executed synchronously with steps S410 to S430. This is not limited in this application.

[0110] When the first device further receives the third function information and the third power consumption information from the second control device, step S450 may be further executed in method 400.

[0111] Optionally, in S450, the first device selects the first control device to process the baseband signal.

[0112] The first device can process the baseband signal by determining to select the first control device from the first control device and the second control device based on the second function information, the second power consumption information, the third function information, the third power consumption information, and the service information. In other words, before determining the first target baseband processing function and the second target baseband processing function, the first device first compares the performance of the first control device with the performance of the second control device and can select the first control device to process the baseband signal. The first control device is a control device with a lower power consumption during processing, whereby the system power consumption can be further reduced.

[0113] Alternatively, the first device can process the baseband signal by determining to select the first control device from the first control device and the second control device based on the first function information, the first power consumption information, the second function information, the second power consumption information, the third function information, the third power consumption information, and the service information. In other words, the first device allocates the baseband processing function by comprehensively considering the function information and power consumption information of each device, and can select the first control device through comparison to process the baseband signal. In all modes that satisfy the required baseband processing function, the power consumption of the mode corresponding to the processing by the first control device is lower.

[0114] Note that in this embodiment of the present application, two control devices are used as an example. The solution in the present application can alternatively be applied to a system including a plurality of control devices and a plurality of radio frequency devices. For the sake of brevity, the details will not be described here again.

[0115] In addition, when the first device selects the first control device to process the baseband signal, the union of at least one first baseband processing function and at least one second baseband processing function can include all of the N required baseband processing functions, where N is a positive integer.

[0116] S460: The first device transmits first indication information to the radio frequency device.

[0117] Correspondingly, the radio frequency device receives the first indication information from the first device.

[0118] The first indication information indicates the first target baseband processing function.

[0119] For example, the first device may determine the first indication information based on the first function information, the first power consumption information, the second function information, and the second power consumption information, and transmit the first indication information to the radio frequency device.

[0120] The first target baseband processing function is the first M required baseband processing functions or the last K required baseband processing functions among N consecutive required baseband processing functions. In addition, the first target baseband processing function includes one or more of at least one first baseband processing function, and M and K are positive integers, M ≤ N, and K ≤ N.

[0121] Note that when the first function information includes an identifier of the first baseband processing function, the first indication information may include an identifier of the first target baseband processing function. Alternatively, when the first function information includes an identifier of the first operating mode, the first indication information may include an identifier of the first target operating mode.

[0122] S470: The first device transmits second indication information to the first control device.

[0123] Correspondingly, the first control device receives the second indication information from the first device.

[0124] The second indication information indicates the second target baseband processing function.

[0125] The second target baseband processing function is a baseband processing function other than the first target baseband processing function among N consecutive required baseband processing functions, and the second target baseband processing function includes one or more of at least one second baseband processing function.

[0126] It should be noted that when the second function information includes an identifier of the second baseband processing function, the second indication information may include an identifier of the second target baseband processing function. When the second function information includes an identifier of the second operating mode, the second indication information may include an identifier of the second target operating mode.

[0127] The first target baseband processing function is the first M required baseband processing functions or the last K required baseband processing functions among N consecutive required baseband processing functions, and it can be understood that it is related to the required baseband processing functions in the application scenario. The scenario shown in Figure 3 is used as an example. In the processing in the uplink direction, generally, the radio frequency device first executes the first target baseband processing function, and then the second control device executes the second target baseband processing function. The first target baseband processing function is the first M required baseband processing functions among N consecutive required baseband processing functions. In the processing in the downlink direction, generally, the first control device first executes the second target baseband processing function, and then the radio frequency device executes the first target baseband processing function. The first target baseband processing function is the last K required baseband processing functions among N consecutive required baseband processing functions.

[0128] Referring to step S460 and step S470, for example, a manner in which the first device determines the first target baseband processing function in the first indication information and the second target baseband processing function in the second indication information will be described hereinafter.

[0129] The first device may determine the first target baseband processing function and the second target baseband processing function based on the first function information, the first power consumption information, the second function information, and the second power consumption information.

[0130] In other words, a manner in which the radio frequency device executes the first target baseband processing function and the first control device executes the second target baseband processing function can satisfy the requirements of the required baseband processing function. In addition, this manner may be a manner with lower power consumption among the manners that satisfy the requirements of the required baseband processing function.

[0131] This format is capable of meeting the requirements of the required baseband processing function. First, the union of the first target baseband processing function and the second target baseband processing function is the required baseband processing function. When the first function information further includes the processing capability information of the first baseband processing function and the second function information further includes the processing capability information of the second baseband processing function, the processing capabilities of the first target baseband processing function and the second target baseband processing function must also meet the processing requirements of the required baseband processing function. In addition, when the first function information further includes bandwidth information, the first device may further determine that the bandwidth meets the bandwidth requirement. For example, the bandwidth information includes the bandwidth value supported by the radio frequency device, and when the bandwidth value is greater than or equal to the first value, the bandwidth meets the bandwidth requirement. The first value is the bandwidth requirement value for processing the baseband signal by the radio frequency device and the first control device. The first value may be set in advance or may be shown to the first device after being determined by the first control device based on the service. When the bandwidth value supported by the radio frequency device is smaller than the bandwidth requirement value, the bandwidth does not meet the bandwidth requirement, and the first device may not need to determine the first target baseband processing function or the second target baseband processing function, and it should be noted that the first device may feedback to the radio frequency device that the bandwidth supported by the radio frequency device does not meet the bandwidth requirement. In this way, the radio frequency device may generate an alarm indicating that the bandwidth is not supported based on the feedback information.

[0132] For example, hereinafter, how the first device determines the first target baseband processing function and the second target baseband processing function will be described by using examples.

[0133] An example where N = 5 is used. The N consecutive required baseband processing functions are Function #1, Function #2, Function #3, Function #4, and Function #5. The baseband processing functions supported by the radio frequency device are Function #1, Function #2, and Function #3, and the baseband processing functions supported by the first control device are Function #2, Function #3, Function #4, and Function #5. In addition, the processing capabilities of the radio frequency device to execute Function #1, Function #2, and Function #3 meet the processing requirements of the required baseband processing functions, and the processing capabilities of the first control device to execute Function #2, Function #3, Function #4, and Function #5 meet the processing requirements of the required baseband processing functions. The bandwidth between the radio frequency device and the first control device also meets the bandwidth requirements.

[0134] For example, the following three modes can satisfy the required baseband processing functions.

[0135] Mode 1: The first target baseband processing function includes Function #1, and the second target baseband processing function includes Function #2, Function #3, Function #4, and Function #5.

[0136] Mode 2: The first target baseband processing function includes Function #1 and Function #2, and the second target baseband processing function includes Function #3, Function #4, and Function #5.

[0137] Mode 3: The first target baseband processing function includes Function #1, Function #2, and Function #3, and the second target baseband processing function includes Function #4 and Function #5.

[0138] The first device may randomly select one of the aforementioned modes, or further, the first device may determine the power consumption corresponding to three modes based on the first power consumption information and the second power consumption information, and determine the mode to be selected for processing. By way of example and not limitation, the power consumption of the baseband processing function supported by a radio frequency device is as follows. The power consumption of function #1 is 10W, the power consumption of function #2 is 40W, and the power consumption of function #3 is 10W. The power consumption of the baseband processing function supported by the first control device is as follows. The power consumption of function #2 is 10W, the power consumption of function #3 is 20W, the power consumption of function #4 is 20W, and the power consumption of function #5 is 10W. It may be known that the power consumption of the aforementioned three modes (where the power consumption here is the total power consumption for executing the baseband processing function) is as follows. The power consumption corresponding to mode 1 is 70W, the power consumption corresponding to mode 2 is 100W, and the power consumption corresponding to mode 3 is 90W. Therefore, mode 1 is the mode with the minimum power consumption among the modes that satisfy the required baseband processing function, and the first device may select mode 1.

[0139] When the first function information and the second function information include operation mode information, the determination by the first device of the first target baseband processing function and the second target baseband processing function may be understood as the determination by the first device of the first target operation mode and the second target operation mode.

[0140] For example, N consecutive required baseband processing functions are Function #1, Function #2, Function #3, Function #4, and Function #5. The operating modes supported by the radio frequency device are Mode #1 (for executing Function #1), Mode #2 (for executing Function #1 and Function #2), and Mode #3 (for executing Function #1, Function #2, and Function #3). The operating modes supported by the first control device are Mode #4 (for executing Function #2, Function #3, Function #4, and Function #5), Mode #5 (for executing Function #3, Function #4, and Function #5), Mode #6 (for executing Function #4 and Function #5), and Mode #7 (for executing Function #5).

[0141] The first device can select three modes that can satisfy the required baseband processing functions.

[0142] Mode 1: The first target operating mode is Mode #1, and the second target operating mode is Mode #4.

[0143] Mode 2: The first target operating mode is Mode #2, and for the first control device, Mode #5 is selected.

[0144] Mode 3: The first target operating mode is Mode #3, and the second target operating mode is Mode #6.

[0145] The first device may randomly select one of the aforementioned modes, or further, based on the first power consumption information and the second power consumption information, the first device may determine the power consumption corresponding to three modes and determine the mode to be selected for baseband processing. In this case, the power consumption information may include the power consumption corresponding to each baseband processing function, or may be the power consumption corresponding to each operating mode. An example where the power consumption information includes the power consumption corresponding to each operating mode is used. The power consumption of the operating modes supported by the radio frequency device is as follows. The power consumption of mode #1 is 10W, the power consumption of mode #2 is 50W, and the power consumption of mode #3 is 60W. The power consumption of the operating modes supported by the first control device is as follows. The power consumption of mode #4 is 60W, the power consumption of mode #5 is 50W, the power consumption of function #6 is 30W, and the power consumption of mode #7 is 10W. It is possible to know that the power consumption of the aforementioned three modes (where the power consumption here is the total power consumption of executing the operating mode) is as follows. The power consumption corresponding to mode 1 is 70W, the power consumption corresponding to mode 2 is 100W, and the power consumption corresponding to mode 3 is 90W. Therefore, mode 1 is the mode with the minimum power consumption among the modes that satisfy the required baseband processing functions, and the first device may select mode 1.

[0146] It should be further noted that when the first device and the first control device are integrated, the first control device can communicate with the first device through the internal interface. In this case, the aforementioned step S420 and the aforementioned step S470 can be optional operations. The first device can obtain information (e.g., second function information and second power consumption information) from the first control device through the internal interface, and the first control device can also obtain information (e.g., second indication information) from the first device through the internal interface. When the first device and the radio frequency device are integrated, the radio frequency device can communicate with the first device through the internal interface. In this case, the aforementioned step S410 and the aforementioned S460 are optional operations. The first device can obtain information (e.g., first function information and first power consumption information) from the radio frequency device through the internal interface, and the radio frequency device can also obtain information (e.g., first indication information) from the first device through the internal interface.

[0147] Therefore, in the present application, the radio frequency device can report to the first device the baseband processing function supported by the radio frequency device and the power consumption corresponding to the baseband processing function. The first device can comprehensively consider the capabilities and power consumptions of the respective devices as needed, select a mode with a low system power consumption, and indicate to the radio frequency device to execute the baseband processing function, thereby reducing the system power consumption.

[0148] FIG. 5 and FIG. 6 are diagrams of the structures of possible devices according to embodiments of the present application. These devices can be configured to implement the functions of the first device and the radio frequency device in the aforementioned method embodiments, and thus it is also possible to achieve the beneficial effects of the aforementioned method embodiments. In the embodiments of the present application, these devices can be the first device and the radio frequency device, or modules (e.g., chips) used in the first device and the radio frequency device.

[0149] As shown in FIG. 5, apparatus 500 includes a processing unit 510 and a transceiver unit 520. Apparatus 500 is configured to implement the functions of the first apparatus or radio frequency apparatus in the method embodiment shown in FIG. 4. Alternatively, apparatus 500 may include a module configured to implement any function or operation of the first apparatus or radio frequency apparatus in the method embodiment shown in FIG. 4. All or part of the module may be implemented by using software, hardware, firmware, or any combination thereof.

[0150] When the device 500 is configured to implement the functions of the first device in the method embodiment shown in FIG. 4, the transceiver unit 520 is configured to receive first function information and first power consumption information from the radio frequency device. The first function information indicates at least one first baseband processing function supported by the radio frequency device, and the first power consumption information indicates the power consumption for implementing each of at least one first baseband processing function by the radio frequency device. The processing unit 510 is configured to generate first indication information. The first indication information indicates a first target baseband processing function, and the first target baseband processing function includes one or more of at least one first baseband processing function. The first indication information is determined based on the first function information, the first power consumption information, the second function information, and the second power consumption information. The second function information indicates at least one second baseband processing function supported by the first control device, and the second power consumption information indicates the power consumption for implementing each of at least one second baseband processing function by the first control device. The transceiver unit 520 is further configured to transmit the first indication information to the radio frequency device. The first target baseband processing function is the first M required baseband processing functions or the last K required baseband processing functions among the N required baseband processing functions. N, M, and K are positive integers, M ≤ N, K ≤ N, and the N required baseband processing functions are the baseband processing functions sequentially executed by the radio frequency device and the first control device during the processing of the baseband signal. The transceiver unit is further configured to transmit the first indication information to the radio frequency device.

[0151] Therefore, in the present application, the radio frequency device may report to the first device the baseband processing function supported by the radio frequency device and the power consumption corresponding to the baseband processing function. The first device may comprehensively consider the capabilities and power consumption of each device as needed, select a mode with a low system power consumption, and indicate to the radio frequency device to execute the baseband processing function, thereby reducing the system power consumption.

[0152] For more detailed descriptions regarding the processing unit 510 and the transceiver unit 520, please directly refer to the relevant descriptions in the method embodiment shown in FIG. 4. Details will not be described here again.

[0153] When the device 500 is configured to implement the functions of the radio frequency device in the method embodiment shown in FIG. 4, the processing unit 510 is configured to generate first function information and first power consumption information. The first function information indicates at least one first baseband processing function supported by the radio frequency device, and the first power consumption information indicates the power consumption for implementing each of at least one first baseband processing function by the radio frequency device. The transceiver unit 520 is configured to transmit the first function information and the first power consumption information to the first device. The transceiver unit 520 is further configured to receive first indication information from the first device. The first indication information indicates a first target baseband processing function, and the first target baseband processing function is one or more of at least one first baseband processing function. The first indication information is determined based on the first function information, the first power consumption information, the second function information, and the second power consumption information. The second function information indicates at least one second baseband processing function supported by the first control device, and the second power consumption information indicates the power consumption for implementing each of at least one second baseband processing function by the first control device. The first target baseband processing function is the first M required baseband processing functions or the last K required baseband processing functions among the N required baseband processing functions. N, M, and K are positive integers, M ≤ N, K ≤ N, and the N required baseband processing functions are the baseband processing functions sequentially executed by the radio frequency device and the first control device during the processing of the baseband signal. The transceiver unit is further configured to transmit the first indication information to the radio frequency device.
