This application relates to the field of communication technology, and more specifically, to a baseband processing method and apparatus. 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 18 May 2022, which is incorporated herein by reference in its entirety. During baseband signal processing, the baseband unit and radio unit in an access network device may process the baseband signal by sequentially executing multiple baseband processing functions based on a pre-configured allocation pattern. In this case, the baseband processing functions performed by the baseband unit and the baseband processing functions performed by the radio unit are fixed. However, for example, because the baseband unit and radio unit have different manufacturing technologies, hardware structures, or operating environments, the overall system power consumption resulting from different allocation patterns during baseband signal processing may differ, and the pre-configured allocation pattern may be the one with the highest power consumption among multiple allocation patterns. Therefore, there is an urgent need for baseband processing methods and devices to reduce system power consumption. This application provides a baseband processing method and apparatus for reducing system power consumption. According to a first embodiment, a baseband processing method is provided.

The first device can, as necessary, comprehensively consider the capabilities and power consumption of each device and, by selecting a mode that results in lower system power consumption, instruct the radio frequency device to perform the baseband processing function, thereby reducing system power consumption. In relation to the first embodiment, in some implementations of the first embodiment, the first functional information includes bandwidth information, where the bandwidth information indicates the bandwidth supported by the radio frequency device, and the bandwidth is greater than or equal to a first value. Therefore, in this application, the radio frequency device can further report its bandwidth capability to the first device, thereby enabling the first device to determine that the radio frequency device is capable of meeting bandwidth requirements and improving the reliability of system baseband processing. In relation to the first embodiment, in some implementations of the first embodiment, the method further includes the step of a first device receiving second function information and second power consumption information from a first control device.
