Description

Communication method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus. Background In a communication system, each fiber-to-room (fiber to the room, FTTR) device may send messages to each terminal device simultaneously during a first concurrency process. However, since the time duration of a Block ACK (BA) frame that different terminal devices respond to different FTTR devices may be different, the start time of each FTTR for sending a message to each terminal device next may be different, which affects the concurrency performance of the communication system. Disclosure of Invention The application provides a communication method and a communication device, which can enable each first device to synchronously send messages to each terminal device in the burst (burst) concurrency process, thereby improving the concurrency performance of a communication system. In a first aspect, the present application provides a communication method, which may be performed by a second device, where the "second device" in the present application may refer to the second device itself, a component (for example, a processor, a chip, or a chip system, etc.) in the second device, or a logic module or software that can implement all or part of the functions of the second device, unless specified otherwise. The method includes receiving first information from one or more first devices and transmitting second information to the one or more first devices, respectively, based on the one or more first information. The first information is used for indicating the duration of the Block Acknowledgement (BA) frame corresponding to the first device, and the second information is used for indicating the synchronous time stamp of the next message transmission of the first device. Based on the first aspect, in the burst concurrency process, each first device may indicate to the second device the duration of the BA frame acquired by each first device, and the second device may determine a synchronization timestamp for each first device according to the duration of the BA frame acquired by each first device, so that each first device may send a message to each terminal device synchronously in the next burst concurrency process according to the synchronization timestamp indicated by the second device, thereby improving concurrency performance of the communication system. In one possible design, the second information is determined according to a maximum value of durations of the BA frames indicated by the one or more first information and the first duration. Based on the possible design, the second device can determine the second information according to the maximum value of the duration of the BA frame corresponding to each first device and the first duration, and can determine the synchronous timestamp capable of realizing synchronous concurrency for each first device on the basis of ensuring that each first device can completely receive the BA frame, thereby improving the concurrency performance of the communication system. In one possible design, the first duration is the duration of a short interframe space SIFS. Based on the possible design, the first time period may be a time period customized by the second device, or the first time period may also be a preset time period, without limitation. The first duration may be a duration of SIFS, for example. In one possible design, the method further includes determining a duration of the BA frame corresponding to the first device according to the BA default timeout time if the first information indicates that the duration of the BA frame corresponding to the first device is equal to 0. Based on the possible design, under the condition that the duration of the BA frame indicated by the first information received by the second device is equal to 0, the second device can determine that the first device does not receive the BA frame fed back by the terminal device, based on the possible design, the second device can determine the duration of the BA frame corresponding to the first device according to the BA default timeout time, so that the subsequent synchronization timestamp can be determined according to the duration of the BA frame conveniently. In one possible design, the first information further comprises one or more of a number of the first device or first indication information, wherein the first indication information is used for indicating the current scheduling information. In one possible design, the first indication information may include one or more of a scheduling number, or an access type AC queue. Based on the two possible designs, when the first device indicates the duration of the BA frame through the first information, the first device may additionally carry one or more of the above information, so as to improve the communication performance. In one possible design, t
