Description

Communication methods and communication devices This application claims priority to Chinese Patent Application No. 202411563212.0, filed with the State Intellectual Property Office of China on November 4, 2024, entitled "Communication Method and Communication Device"; priority to Chinese Patent Application No. 202411758013.5, filed with the State Intellectual Property Office of China on November 29, 2024, entitled "Communication Method and Communication Device"; and priority to Chinese Patent Application No. 202510042357.4, filed with the State Intellectual Property Office of China on January 9, 2025, entitled "Communication Method and Communication Device", the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of optical communications, and more particularly to communication methods and communication devices. Background Technology Fiber to the room (FTTR) is a solution that brings fiber optic cables to every room, enabling home networks to achieve ultra-high contracted bandwidth and cover every corner of the home, thereby meeting user needs. FTTR networks typically consist of multiple FTTR units (FUs). These FUs provide communication services to terminals via wireless local area networks (WLANs). If these multiple FTTR units are located in the same physical space and operate on the same wireless frequency band, parallel data transmission between them can cause signal interference in overlapping areas, thus affecting the communication performance of the terminals. Summary of the Invention This application provides a communication method and a communication device that help avoid mutual interference between multiple FTRR devices in the same frequency band, thereby improving the communication performance of the terminal. Firstly, this application provides a communication method that can be executed by a communication device. The communication device can be a communication equipment, or one or more of the following: a module, apparatus, processor, chip, or circuit configured for use in or in conjunction with a communication device. For example, this communication device includes an FTTR device, which can be referred to as a main FTTR device. This communication method includes: receiving cooperative space multiplexing capability information, which is used to indicate whether the first FTTR device supports at least one of the following capabilities: actively reporting cooperative space multiplexing related information, responding to the instruction of the master FTTR device to report cooperative space multiplexing related information, synchronously sending messages, asynchronously sending messages, or actively sending synchronization messages. In this communication method, the master FTTR can obtain more reasonable collaborative space multiplexing scheduling information based on the collaborative space multiplexing capability information of the first FTTR device. This can avoid interference between FTTR devices with higher efficiency or higher accuracy, thereby improving the communication performance of the terminal with higher efficiency or higher accuracy. Among them, collaborative space reuse capability information can be referred to as space reuse capability information, and proactively reporting collaborative space reuse related information and responding to the instructions of the master FTTR device to report collaborative space reuse related information can be collectively referred to as reporting space reuse related information. In some possible implementations, the collaborative spatial reuse capability information may also include: the identifier of the first FTTR device, and/or, the operating frequency band. The collaborative space reuse capability information includes the identifier of the first FTTR device, which helps the master FTTR device to accurately know that the collaborative space reuse capability information is the collaborative space reuse capability information of the first FTTR device, thereby enabling it to accurately collect relevant information of the first FTTR device or accurately schedule the first FTTR device. The cooperative spatial reuse capability information includes the operating frequency band, which helps the master FTTR device determine which operating frequency band of the first FTTR device the cooperative spatial reuse capability information belongs to. This allows for more accurate reduction of interference between FTTR devices targeting that operating frequency band, thereby accurately improving the communication performance of the terminal. In some possible implementations, before receiving the cooperative space reuse capability information, the communication method further includes: sending cooperative space reuse capability request information, which is used to instruct the first FTTR device to report the cooperative space reuse capability information. In this implementation, the master FTTR device c
