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 in its entirety.

[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.

[0057] To facilitate understanding of the embodiments of this application, the application scenarios of the embodiments of this application will be described in detail, with reference to Figure 1.

[0058] Figure 1 is a diagram illustrating the structure of a communication system to which the embodiments of this application can be applied. The devices that may be included in this communication system are described first.

[0059] Radio unit (RU) 110: The radio unit 110 may perform functions such as intermediate frequency processing, radio frequency processing, and redundancy 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 capable of intermediate frequency signal processing, radio frequency signal processing, or intermediate radio frequency signal processing.

[0060] Baseband unit (BU) 120: The baseband unit 120 may perform the function of processing baseband signals. For example, the baseband unit 120 may include at least one of a central unit (CU) and a distributed unit (DU), or another network element or communication device that has the capability to process baseband signals. For example, the baseband unit is sometimes abbreviated as BBU.

[0061] 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 common public radio interface (eCPRI), or another interface to be defined in the future for connecting the baseband unit 120 and the radio unit 110.

[0062] Scheduling Unit 130: The scheduling unit 130 can schedule the baseband processing functions of the baseband unit 120 and the radio unit 110. For example, the scheduling unit 130 can schedule one or more baseband processing functions to be performed by the baseband unit 120 and one or more baseband processing functions to be performed by the radio unit 110, based on service requirements.

[0063] The scheduling unit 130 and the baseband unit 120 may be deployed together, or the scheduling unit 130 and the radio unit 110 may be deployed together, or the scheduling unit 130, the radio unit 110, and the baseband unit 120 may be deployed separately. For example, if the scheduling unit 130 and the baseband unit 120 are deployed together, the scheduling unit 130 may communicate with the baseband unit 120 through an internal interface, or with the radio unit 110 through an interface. If the scheduling unit 130 and the radio unit 110 are deployed together, the scheduling unit 130 may communicate with the radio unit 110 through an internal interface, or with the baseband unit 120 through an interface. When the scheduling unit 130, the radio unit 110, and the baseband unit 120 are deployed separately, the scheduling unit 130 may communicate with the baseband unit 120 through an interface with the baseband unit 120, and 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 with the radio unit 110 through the baseband unit 120. This is not particularly limited in this application.

[0064] A distributed base station may include at least one baseband unit and at least one radio unit. Hereafter, with reference to Figure 2, we will describe systems having multiple architectures to which the baseband unit and radio unit can be applied.

[0065] Figure 2 is a diagram illustrating the structure of a system having multiple architectures to which embodiments of this application are applicable. An example of this system including 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 Figure 1, and the radio units 220 and 230 may each be the radio units 110 in Figure 1. In this application, examples of this system including a direct connection system and a cascaded system are used for description. For the direct connection system, see Figure 2(a). The baseband unit 210 is directly connected separately to the radio units 220 and 230. The baseband unit 210 communicates separately directly through the interfaces of the radio unit 220 and the radio unit 230. For the cascaded system, see Figure 2(b). The baseband unit 210 is directly connected to the radio unit 220. The wireless unit 220 is directly connected to the wireless unit 230. The baseband unit 210 communicates directly with the wireless unit 220. The baseband unit 210 can communicate with the wireless unit 230 through the wireless unit 220.

[0066] The above merely describes systems having some architectures to which this embodiment of the present application is applicable. Alternatively, the embodiments of the present application are applicable to other systems having an architecture in which a wireless unit can communicate with a baseband unit. 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 this application can be applied.

[0068] Refer to Figure 3. In the downlink direction, the baseband signal may be processed in the following order: 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 following order: analog beamforming, analog to digital conversion, fast Fourier transformation (FFT), cyclic prefix removal, digital beamforming, resource element demapping, channel estimation, equalization, demodulation, descrambling, rate dematching, and decoding.

[0069] In this embodiment of the present application, it should be noted that the baseband processing function may be any one of the processing functions described above, or it may be a combination of the processing functions described above. For example, FFT and cyclic prefix rejection may be considered a single baseband processing function. The aforementioned baseband processing functions may be performed by a baseband unit or by a radio unit. For example, in the downlink direction, the baseband unit sequentially performs encoding, rate matching, scrambling, modulation, layer mapping, precoding, and resource element mapping on a baseband signal, and then the radio unit sequentially performs digital beamforming, IFFT, cyclic prefix addition, analog beamforming, and digital-to-analog conversion on the signal processed by the baseband unit. In addition, the baseband unit and the radio unit may have the capability to perform the same baseband processing function. The baseband processing function shown in Figure 3 is used as an example, and this embodiment of the present application may be applied as an alternative to other procedures or procedures of baseband processing functions to be defined in the future.

When the first device, the first control unit, and the radio frequency device are located separately, the first device, the first control unit, and the radio frequency device may transmit information through an external interface. Hereafter, the case in which the first device, the first control unit, and the radio frequency device are located separately will be used as an example for description. This method may include the following steps.

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

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

[0074] The first functional 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 Figure 3.

[0075] In possible implementations, the first functional information includes an identifier for at least one first baseband processing function supported by the radio frequency device. The identifier for at least one first baseband processing function identifies at least one first baseband processing function. The first device can know the baseband processing function supported by the radio frequency device based on the identifier for the first baseband processing function.

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

[0077] Specifically, the first device may pre-configure mapping relationships between identifiers of a first operating mode and identifiers of baseband processing functions. One operating mode identifier may correspond to some or all identifiers of the first baseband processing functions. For example, if the first operating mode is an operating mode used when the radio frequency device performs digital-to-analog conversion and analog beamforming, the mapping relationships include correspondences between the identifier of the first operating mode and the identifiers of digital-to-analog conversion and analog beamforming, so that the first device can determine the baseband processing functions supported by the radio frequency device based on the identifier of the first operating mode and the mapping relationships.

[0078] Optionally, the first functional information may further include processing capability information corresponding to each first baseband processing function. For example, the first functional information may further include at least one of the following: the number of users supported when the radio frequency device performs each first baseband processing function; the number of data streams or service streams supported when the radio frequency device performs each first baseband processing function; and the number of resource blocks supported when the radio frequency device performs each first baseband processing function.

[0079] The number of users supported when the radio frequency device performs baseband processing may be the maximum number of users that can be scheduled when the radio frequency device performs baseband processing. The number of data streams or service streams supported when the radio frequency device performs baseband processing may be the maximum number of data streams or service streams that can be scheduled when the radio frequency device performs baseband processing. The number of resource blocks supported when the radio frequency device performs baseband processing may be the maximum number of resource blocks (RBs) that can be scheduled when the radio frequency device performs baseband processing. The first device assigns baseband processing functions based on functional information, thereby ensuring that the baseband processing functions assigned to the radio frequency device are within the capabilities of the radio frequency device, further improving the reliability of system baseband processing.

[0080] Optionally, the first functional information may further include bandwidth information, which indicates the bandwidth supported by the radio frequency device.

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

[0082] For example, the first functional information may include a bandwidth value. Alternatively, the first functional information may include parameter values ​​such as interface speed or throughput, thereby enabling the first device to know the bandwidth supported by the radio frequency device based on the parameter values, and to determine that the radio frequency device is capable of meeting the bandwidth requirements, thereby improving the reliability of system baseband processing.

[0083] The first power consumption information indicates the power consumption of performing each of at least one of the first baseband processing functions by the radio frequency device.

[0084] The first power consumption information may include the power consumption values ​​for performing each first baseband processing function by the radio frequency device. For example, the power consumption value for performing digital-to-analog conversion by the 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 the power consumption levels for performing each of the first baseband processing functions by the radio frequency device. For example, the power consumption level for performing digital-to-analog conversion by the 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 consumption of performing multiple first baseband processing functions during baseband signal processing. Similarly, the second power consumption level is the lowest among the power consumption of performing multiple first baseband processing functions. Power consumption levels may be classified by the radio frequency device based on a predetermined algorithm and on power consumption values.

[0086] Accordingly, if the first functional information includes operating mode information, the first device may determine the power consumption corresponding to the first operating mode based on the operating mode information.

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

[0088] The first power consumption information may include power consumption values ​​for performing each first baseband processing function by the radio frequency device, thereby enabling the first device to obtain power consumption corresponding to the first operating mode based on the power consumption values ​​corresponding to the baseband processing function.

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

[0090] Alternatively, the first power consumption information may include the power consumption level of implementing each first operating mode by the radio frequency device, or other information that can indicate the power consumption corresponding to the first operating mode. This is not particularly limited in this application.

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

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

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

[0094] The second power consumption information indicates the power consumption of the first control device to perform each of at least one of the second baseband processing functions.

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

[0096] In possible implementations, the second functional information includes an identifier for at least one second baseband processing function supported by the first control unit. The identifier for at least one second baseband processing function identifies at least one second baseband processing function. Based on the identifier for the second baseband processing function, the first device can know which baseband processing function is supported by the first control unit.

[0097] In another possible implementation, the second functional information includes operating mode information, which indicates at least one second operating mode supported by the first control unit. The second operating mode is the operating mode used when the second control unit performs one or more of at least one second baseband processing function.

[0098] Optionally, the first functional information may further include processing capacity information corresponding to each of the second baseband processing functions. For example, the second functional information may further include at least one of the following: the number of users supported when the first control unit performs each of the second baseband processing functions; the number of data streams or service streams supported when the first control unit performs each of the second baseband processing functions; and the number of resource blocks supported when the first control unit performs each of the second baseband processing functions.

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

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

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

[0102] The third functional information indicates at least one third baseband processing function supported by the second control unit. The third power consumption information indicates the power consumption of performing each of the at least one third baseband processing function by the second control unit.

[0103] The description of the third functional information and the third power consumption information is the same as the description of the first functional information and the first power consumption information in step S410. For brevity, the details will not be described again here.

[0104] It should be noted that the radio frequency device, the first control unit, and the second control unit may all support the same baseband processing function. For example, the radio frequency device, the first control unit, and the second control unit may all support analog beamforming. However, the corresponding power consumption for performing the same baseband processing function by the radio frequency device, the first control unit, and the second control unit may differ. For example, the power consumption for performing analog beamforming and processing data by the radio frequency device is 20W, the power consumption for performing analog beamforming and processing the same data by the first control unit is 30W, and the power consumption for performing analog beamforming and processing the same data by the second control unit is 40W.

[0105] The N required baseband processing functions may be baseband processing functions that are sequentially executed by the radio frequency device and control device (first control device or second control device) during the processing of the baseband signal. The baseband processing functions shown in Figure 3 may be an example of the N required baseband processing functions. The first device may know the required baseband processing functions based on pre-configured 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 performed in method 400.

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

[0107] For example, the first control device may predict future service loads, generate service information, and transmit that service information to the first device. Based on the service information, the first device may determine N required baseband processing functions to be executed sequentially to process the service, thereby allowing the first device to assign the N required baseband processing functions to radio frequency devices and control devices (the first or 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 performed by the radio frequency device, and / or requirement information corresponding to one or more specific required baseband processing functions performed by the control device. For example, the requirement information indicates at least one of the following: a requirement for the number of users when the radio frequency device performs one or more specific required baseband processing functions, a requirement for the number of streams when the radio frequency device performs one or more specific required baseband processing functions, or a requirement for the number of resource blocks when the radio frequency device performs one or more specific required baseband processing functions. In this manner, the first device may determine, based on the requirement information and the processing capability information of the radio frequency device, whether the requirements indicated by the requirement information can be met when the radio frequency device performs one or more specific required baseband processing functions.

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

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

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

[0112] The first device may process a baseband signal by deciding to select the first control unit from the first and second control units based on second functional information, second power consumption information, third functional information, third power consumption information, and service information. In other words, before determining the first target baseband processing function and the second target baseband processing function, the first device may first compare the performance of the first control unit with the performance of the second control unit and select the first control unit to process the baseband signal. The first control unit is a control unit that consumes even less power during processing, thereby further reducing the system power consumption.

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

[0114] It should be noted that in this embodiment of the present application, two control devices are used as an example. Alternatively, the solution in this application may be applied to a system comprising multiple control devices and multiple radio frequency devices. For brevity, further details will not be described here.

[0115] In addition, if 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 may include all N required baseband processing functions, where N is a positive integer.

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

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

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

[0119] For example, the first device may determine first indication information based on first function information, first power consumption information, second function information, and second power consumption information, and transmit the first indication information to a 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 out of N consecutive required baseband processing functions. In addition, the first target baseband processing function includes at least one or more of the first baseband processing functions, where M and K are positive integers, M ≤ N, and K ≤ N.

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

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

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

[0124] The second indication information shows 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 at least one or more of the second baseband processing functions.

[0126] Note that if the second functional information includes an identifier for the second baseband processing function, the second indication information may include an identifier for the second target baseband processing function. If the second functional information includes an identifier for the second operating mode, the second indication information may include an identifier for the second target operating mode.

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

[0128] Referring to steps S460 and S470, for example, a method by 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 below.

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

[0130] In other words, a configuration in which the radio frequency device performs a first target baseband processing function and the first control device performs a second target baseband processing function can satisfy the requirements for the necessary baseband processing functions. In addition, this configuration may have lower power consumption than other configurations that satisfy the requirements for the necessary baseband processing functions.

[0131] This format can satisfy the requirements for the necessary baseband processing functions. First, the union of a first target baseband processing function and a second target baseband processing function is the required baseband processing function. If the first functional information further includes processing capability information for the first baseband processing function, and the second functional information further includes processing capability information for the second baseband processing function, then the processing capabilities of the first target baseband processing function and the second target baseband processing function must also satisfy the processing requirements for the required baseband processing function. In addition, if the first functional information further includes bandwidth information, the first device may further determine that the bandwidth satisfies the bandwidth requirement. For example, the bandwidth information includes a bandwidth value supported by the radio frequency device, and if that bandwidth value is greater than or equal to a first value, then the bandwidth satisfies the bandwidth requirement. The first value is the bandwidth requirement value for processing baseband signals by the radio frequency device and the first control device. The first value may be pre-set or may be shown to the first device after being determined by the first control device based on service. Note that if 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 does not need to determine the first or second target baseband processing function, but can instead provide feedback to the radio frequency device that the bandwidth supported by the radio frequency device does not meet the bandwidth requirement. In this manner, the radio frequency device may generate an alarm indicating that the bandwidth is not supported based on the feedback information.

[0132] For example, the following will describe, using examples, how the first device determines the first target baseband processing function and the second target baseband processing function.

[0133] An example with 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 unit are function #2, function #3, function #4, and function #5. In addition, the processing capability of the radio frequency device to perform function #1, function #2, and function #3 satisfies the processing requirements for the required baseband processing functions, and the processing capability of the first control unit to perform function #2, function #3, function #4, and function #5 satisfies the processing requirements for the required baseband processing functions. The bandwidth between the radio frequency device and the first control unit also satisfies the bandwidth requirements.

[0134] For example, the following three formats can satisfy the required baseband processing capabilities.

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

[0136] Form 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] Form 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 the three modes based on the first and second power consumption information to determine which mode will be selected for processing. As an example, and not an limitation, the power consumption of the baseband processing functions supported by the radio frequency device is as follows: Function #1 has a power consumption of 10W, function #2 has a power consumption of 40W, and function #3 has a power consumption of 10W. The power consumption of the baseband processing functions supported by the first control device is as follows: Function #2 has a power consumption of 10W, function #3 has a power consumption of 20W, function #4 has a power consumption of 20W, and function #5 has a power consumption of 10W. It is possible to know that the power consumption of the three aforementioned modes (where power consumption is the sum of the power consumption for performing the baseband processing functions) is as follows: The power consumption corresponding to Form 1 is 70W, the power consumption corresponding to Form 2 is 100W, and the power consumption corresponding to Form 3 is 90W. Therefore, Form 1 is the form with the lowest power consumption among the forms that satisfy the required baseband processing function, and the first device may select Form 1.

[0139] If the first functional information and the second functional information include operating mode information, the determination of the first target baseband processing function and the second target baseband processing function by the first device can be understood as the determination of the first target operating mode and the second target operating mode by the first device.

[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 performing function #1), mode #2 (for performing functions #1 and #2), and mode #3 (for performing functions #1, #2, and #3). The operating modes supported by the first control unit are mode #4 (for performing functions #2, #3, #4, and #5), mode #5 (for performing functions #3, #4, and #5), mode #6 (for performing functions #4 and #5), and mode #7 (for performing function #5).

[0141] The first device can be selected from three configurations capable of meeting the required baseband processing capabilities.

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

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

[0144] Form 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, the first device may determine the power consumption corresponding to the three modes based on the first and second power consumption information to determine which mode will be selected for baseband processing. In this case, the power consumption information may include the power consumption corresponding to each baseband processing function, or it may be the power consumption corresponding to each operating mode. An example is used in which the power consumption information includes the power consumption corresponding to each operating mode. The power consumption of the operating modes supported by the radio frequency device is as follows: Mode #1 has a power consumption of 10W, Mode #2 has a power consumption of 50W, and Mode #3 has a power consumption of 60W. The power consumption of the operating modes supported by the first control device is as follows: Mode #4 has a power consumption of 60W, Mode #5 has a power consumption of 50W, Function #6 has a power consumption of 30W, and Mode #7 has a power consumption of 10W. It can be seen that the power consumption of the three modes described above (where power consumption is the sum of the power consumption for performing the operating modes) 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 lowest power consumption among the modes that satisfy the required baseband processing function, and the first device may select Mode 1.

[0146] It should be further noted that if the first device and the first control unit are integrated, the first control unit may communicate with the first device through an internal interface. In this case, steps S420 and S470 described above may be optional operations. The first device may obtain information (e.g., second function information and second power consumption information) from the first control unit through the internal interface, and the first control unit may also obtain information (e.g., second indication information) from the first device through the internal interface. If the first device and the radio frequency device are integrated, the radio frequency device may communicate with the first device through an internal interface. In this case, steps S410 and S460 described above are optional operations. The first device may 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 may also obtain information (e.g., first indication information) from the first device through the internal interface.

[0147] Accordingly, in this 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 that baseband processing function. The first device may, as necessary, comprehensively consider the capabilities and power consumption of each device and reduce system power consumption by instructing the radio frequency device to perform the baseband processing function in a manner that results in lower system power consumption.

[0148] Figures 5 and 6 illustrate the structure of possible devices according to embodiments of the present application. These devices may be configured to perform the functions of the first device and radio frequency device in the method embodiments described above, and thus may achieve the beneficial effects of the method embodiments described above. In embodiments of the present application, these devices may be the first device and radio frequency device, or a module (e.g., a chip) used in the first device and radio frequency device.

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

[0150] If the device 500 is configured to perform the functions of the first device in the method embodiment shown in Figure 4, the transceiver unit 520 is configured to receive first function information and first power consumption information from the radio frequency device, wherein 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 of the radio frequency device performing each of the at least one first baseband processing function.

The transceiver unit 520 is further configured to transmit first indication information to a radio frequency device, wherein the first target baseband processing function is the first M or last K required baseband processing functions out of N required baseband processing functions, where N, M, and K are positive integers, M ≤ N, K ≤ N, and the N required baseband processing functions are baseband processing functions that are sequentially executed by the radio frequency device and the first control device during baseband signal processing. The transceiver unit is further configured to transmit first indication information to a radio frequency device.

[0151] Accordingly, in this 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 that baseband processing function. The first device may, as necessary, comprehensively consider the capabilities and power consumption of each device and reduce system power consumption by selecting a mode that results in lower system power consumption and indicating to the radio frequency device that it should perform the baseband processing function.

[0152] For further details regarding the processing unit 510 and the transceiver unit 520, please refer directly to the relevant descriptions in the method embodiment shown in Figure 4. Further details will not be described again here.

[0153] If the device 500 is configured to perform the functions of the radio frequency device in the method embodiment shown in Figure 4, the processing unit 510 is configured to generate first function information and first power consumption information, wherein 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 of performing each of the 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 indicating a first target baseband processing function, the first target baseband processing function being one or more of at least one first baseband processing function, the first indication information being determined based on first function information, first power consumption information, second function information, and second power consumption information, the second function information indicating at least one second baseband processing function supported by the first control unit, and the second power consumption information indicating the power consumption of the first control unit performing each of the at least one second baseband processing function. The first target baseband processing function is the first M or last K required baseband processing functions out of N required baseband processing functions, where N, M, and K are positive integers, M ≤ N, K ≤ N, and the N required baseband processing functions are baseband processing functions that are sequentially executed by the radio frequency device and the first control device during baseband signal processing. The transceiver unit is further configured to transmit first indication information to the radio frequency device.

[0154] Accordingly, in this 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 that baseband processing function. The first device may, as necessary, comprehensively consider the capabilities and power consumption of each device and reduce system power consumption by selecting a mode that results in lower system power consumption and indicating to the radio frequency device that it should perform the baseband processing function.

[0155] For further details regarding the processing unit 510 and the transceiver unit 520, please refer directly to the relevant descriptions in the method embodiment shown in Figure 4. Further details will not be described again here.

[0156] As shown in Figure 6, the device 600 includes a processor 610 and optionally further includes an interface circuit 620. The processor 610 and the interface circuit 620 are coupled to each other. It can be understood that the interface circuit 620 may be a transceiver or an input / output interface.
