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 202411563138.2, 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 receiving collaborative spatial multiplexing related information, wherein the collaborative spatial multiplexing related information comprises downlink transmission information of each terminal in at least one terminal, the at least one terminal is a terminal communicated with first FTTR equipment, the first FTTR equipment is one of a plurality of FTTR equipment with the same working frequency band, and sending collaborative spatial multiplexing scheduling information according to the collaborative spatial multiplexing related information, and the collaborative spatial multiplexing scheduling information comprises sending power of a message sent by the first FTTR equipment to the first terminal. In some possible implementations, the plurality FTTR of devices may be referred to as slave FTTR devices. By executing the communication method provided in the first aspect, the master FTTR device indicates the cooperative spatial multiplexing scheduling information to the slave FTTR device, and in the case that the slave FTTR device supports receiving the cooperative spatial multiplexing scheduling information and sends a message according to the cooperative spatial multiplexing scheduling information, the power of the message sent from the FTTR device to the terminal in the same frequency band can be controlled or adjusted, that is, the signal coverage of the slave FTTR device is controlled or adjusted, so that the difference between the signal-to-noise ratio of the signal received by the terminal from the first FTTR device and the signal-to-noise ratio of the signal received by the terminal from the other FTTR devices in the same frequency band is controlled, so that the difference can enable the terminal to correctly analyze the signal received by the terminal from the first FTTR device, thereby helping to avoid the terminal from being interfered by the signal of the other FTTR devices, and further helping to improve the communication performance of the terminal. In the communication method, because the collaborative spatial multiplexing related information comprises the downlink transmission information of the terminal, the main FTTR can obtain more reasonable collaborative spatial multiplexing scheduling information based on the collaborative spatial multiplexing related information, so that interference among the auxiliary FTTR devices can be avoided with higher efficiency or higher accuracy, and the communication performance of the terminal can be improved with higher efficiency or higher accuracy. In some possible implementations, the downlink transmission information includes at least one of an identification of each terminal, a transmission rate of each terminal, a number of TIDs with data in TIDs of each terminal, or transmission information of each TID with data in TIDs of each terminal. Based on the information, the master FTTR can obtain more reasonable collaborative spatial
