Description

Communication method and communication device The present application claims priority to the national intellectual property office, application number 202411563212.0, chinese patent application entitled "communication method and communication device" filed 11/04 in 2024, and priority to the national intellectual property office, application number 202411758013.5, chinese patent application entitled "communication method and communication device" filed 11/29 in 2024, the entire contents of which are incorporated herein by reference. Technical Field The present application relates to the field of optical communications, and in particular, to a communication method and a communication device. Background The fiber-to-room (Fiber To The Room, FTTR), i.e., the fiber-to-each-room approach, enables a home network to achieve ultra-high subscription bandwidth and cover every corner of the home, thus meeting user needs. A plurality of FTTR devices (FTTR unit, FU) are typically included in FTTR networks. The plurality of FUs provide communication services for the terminal through (wireless local area networks, WLAN). If the plurality of FTTR devices are in the same physical space and operate in the same radio frequency band, when data is transmitted in parallel between the plurality of FTTR devices, the signal range overlapping area of the plurality of FTTR devices will generate a problem of mutual interference of signals, thereby affecting the communication performance of the terminal. Disclosure of Invention The application provides a communication method and a communication device, which are beneficial to avoiding mutual interference among a plurality of FTRR devices in the same frequency band, thereby improving the communication performance of a terminal. In a first aspect, the present application provides a communication method, which may be performed by a communication apparatus, which may be a communication device, or may be one or more of a module, apparatus, processor, chip or circuit configured for use in or with a communication device. For example, the present communication apparatus includes FTTR devices, which FTTR devices may be referred to as master FTTR devices. The communication method comprises the steps of receiving collaborative spatial multiplexing capability information, wherein the collaborative spatial multiplexing capability information is used for indicating whether a first FTTR device supports at least one of the following capabilities, namely actively reporting collaborative spatial multiplexing related information, responding to an instruction of a main FTTR device to report collaborative spatial multiplexing related information, synchronously transmitting a message, asynchronously transmitting a message or actively transmitting a synchronous message. In the communication method, the master FTTR can obtain more reasonable collaborative spatial multiplexing scheduling information based on the collaborative spatial multiplexing capability information of the first FTTR device, so that interference between the slave FTTR devices can be avoided with higher efficiency or higher accuracy, and further, the communication performance of the terminal can be improved with higher efficiency or higher accuracy. The collaborative spatial multiplexing capability information may be referred to as spatial multiplexing capability information, and the active reporting of collaborative spatial multiplexing related information and the reporting of collaborative spatial multiplexing related information in response to an instruction of the main FTTR device may be collectively referred to as reporting of spatial multiplexing related information. In some possible implementations, the collaborative spatial multiplexing capability information further includes an identification of the first FTTR device and/or an operating frequency band. The identifier of the first FTTR device is included in the collaborative spatial multiplexing capability information, which is helpful for the master FTTR device to accurately acquire that the collaborative spatial multiplexing capability information is the collaborative spatial multiplexing capability information of the first FTTR device, so that the relevant information of the first FTTR device can be accurately collected or the first FTTR device can be accurately scheduled. The cooperative spatial multiplexing capability information comprises the working frequency band, so that the main FTTR equipment is helped to determine which working frequency band of the first FTTR equipment is the cooperative spatial multiplexing capability information, and interference among FTTR equipment can be reduced more accurately for the working frequency band, and the communication performance of the terminal is improved accurately. In some possible implementations, before receiving the collaborative spatial multiplexing capability information, the communication method further includes sending collabo
