Description

Communication method and device Technical Field The embodiment of the application relates to the field of communication, in particular to a communication method and device. Background In a wireless access scenario, a coverage area of a single Access Point (AP) is limited, and in a larger area or an area with a high requirement on network quality, a plurality of access points are typically deployed, where the plurality of access points provide a unified wireless network access service. For example, within a building, multiple sets of fiber-to-room (fiber to the room, FTTR) systems are deployed, with FTTR devices in the multiple sets FTTR providing uniform wireless network access services. However, in FTTR systems, there may be interference between the devices, but there is currently no solution for reporting relevant measurements of interference. Disclosure of Invention The application provides a communication method and a communication device, which can realize the acquisition of interference information of an interference source of a sub optical network unit (SFU). In a first aspect, a communication method is provided, where the method may be performed by a first SFU, or may be performed by a component of the first SFU, for example, a processor, a chip, or a system-on-chip of the first SFU, or may be implemented by a logic module or software that may implement all or part of the functionality of the first SFU. The method comprises the steps of obtaining interference information of an interference source of a first SFU, wherein the interference information of the interference source comprises at least one of identity information corresponding to the interference source, frequency domain information of the interference source or signal strength of the interference source, and sending the interference information of the interference source of the first SFU to a main optical network unit (master fiber unit, MFU). Based on the scheme, the SFU can acquire and report the interference information of the interference source of the SFU, such as the identity information, the frequency domain information, the signal strength and the like of the interference source, so that the MFU can acquire the interference information of the interference source of the SFU, such as the identity, the working frequency band, the interference strength and the like of the interference source of the SFU, so that the interference condition among devices in the global is known, and reasonable scheduling, configuration and the like can be performed based on the global interference condition, and the communication performance is improved. In one possible design, the identity information corresponding to the interferer includes at least one of an identity BSSID of the basic service set to which the interferer belongs, a medium access control MAC address of the interferer, or an identity of the interferer. In one possible design, the frequency domain information of the interferer includes at least one of an operating frequency band of the interferer, an operating channel of the interferer, or an operating bandwidth of the interferer. In one possible design, the interference information for the interferer may further include at least one of a receive-side signal-to-noise ratio, SNR, transmit-side signal-to-noise ratio, type of interferer, or mode of operation. Illustratively, the signal-to-noise ratio SNR at the receiving side is measured by the first SFU, which may be understood as the signal-to-noise ratio at which the first SFU receives the frame of the interferer, i.e. the first SFU may determine the signal-to-noise ratio SNR at the receiving side from the received frame of the interferer. The signal-to-noise ratio SNR of the transmitting side is measured by an interference source (such as an associated site of the first SFU) and reported to the first SFU. The type of interferer is an AP or a station, i.e. indicates whether the interferer is an AP or a station. The working mode is the IEEE standard or Wi-Fi standard used by the interference source. Based on the possible design, the SFU can report richer interference information, so that the MFU obtains more detailed and comprehensive interference conditions, the rationality and the accuracy of subsequent scheduling and configuration are improved, and the communication performance is further improved. In one possible design, obtaining interference information of an interference source of a first SFU includes receiving interference measurement control information from the MFU, the interference measurement control information indicating the first SFU to perform interference measurement, and obtaining the interference information of the interference source of the first SFU according to the interference measurement control information. Based on the possible design, the MFU can actively control the SFU to report the interference information of the interference source, so that the MFU can flexibly
