Description

Communication method and communication device The present application claims priority from the application filed on 11.04.2024 to the national intellectual property agency, application number 202411564954.5, patent application entitled "communication method and communication device", 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 sending cooperative information, wherein the cooperative information comprises synchronous mark information, the synchronous mark information indicates whether a first FTTR device needs to send a message synchronously with other FTTR devices, the working frequency band of the first FTTR device is the same as that of the other FTTR devices, and the cooperative information is sent to the first FTTR device. In some possible implementations, the first FTTR device and the other FTTR devices may be referred to as slave FTTR devices. In some possible implementations, the need to send messages synchronously may be understood as sending messages asynchronously. In the communication method, the master FTTR device indicates to the slave FTTR device whether the slave FTTR device needs to send the message synchronously with other FTTR devices, so that the slave FTTR device knows whether the message is sent synchronously or asynchronously, and the slave FTTR device can be controlled to send the message in a reasonable mode so as to avoid the problem of signal interference with other slave FTTR devices, and the communication performance of the terminal is improved. In some possible implementations, when the synchronization mark information indicates that the first FTTR device needs to send a message synchronously with other FTTR devices, the cooperative information further includes synchronization type information, where the synchronization type information indicates that the message is sent according to a start sending timestamp, the message is sent based on a time triggered by the synchronization message, or the message is sent based on a time triggered by the synchronization message and the synchronization message is triggered by other synchronization messages. When the master FTTR device instructs the first FTTR device to send a message synchronously with other FTTR devices, the master FTTR device also instructs the first FTTR device to send a message synchronously with other FTTR devices, so that the first FTTR device accurately knows the mode of implementing the message synchronous sending, thereby accurately implementing the message synchronous sending. In some possible implementations, the synchronization type information indicates that when the message is transmitted according to the start transmission time stamp, the collaboration information further includes indication information of the start transmission time stamp. In this implementation, the master FTTR device indicates to the slave FTTR device to start sending the timestamp, so that the slave FTTR device can achieve synchronous sending of the messages in a simple manner. In some possible implementations, when the synchronization type information indicates that the message is sent based on the time triggered by the first synchronization message, or when the synchronization type information indicates that the message is sent based
