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 fiber-to-room (fiber to the room, FTTR) networking, a master FTTR unit (main FTTR unit, MFU) may connect one or more slave FTTR units (sub FTTR unit, SFU). The MFU can operate scheduling according to the cache information reported by each SFU, and sends scheduling results to each SFU. And the SFU operates a local scheduling flow according to the received scheduling result, and prepares for air interface transmission according to the scheduling result of the local operation. However, in the above manner, the preparation time delay before each SFU performs air interface transmission is relatively large, and the running time of the scheduling procedure corresponding to each SFU 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 reduce the preparation time delay before each first device performs air interface transmission, and can ensure that each first device can synchronously perform air interface transmission and improve the space multiplexing performance of a communication system. In a first aspect, the present application provides a communication method, which may be performed by a first device, where the "first device" in the present application may refer to the first device itself, a component (for example, a processor, a chip, or a chip system, etc.) in the first device, or a logic module or software that can implement all or part of the functions of the first device, unless specifically stated otherwise. The method comprises the steps of sending a scheduling request to second equipment, wherein the scheduling request comprises a first scheduling result which is obtained by locally pre-scheduling the first equipment, receiving a scheduling instruction from the second equipment, and performing air interface sending according to the scheduling instruction, wherein the scheduling instruction is determined according to the first scheduling result. Based on the first aspect, each first device can perform local pre-scheduling first, then the second device performs centralized scheduling according to the first scheduling result of each first device, each first device can form a scheduling result after receiving a scheduling instruction sent by the second device based on the centralized scheduling, and air interface transmission is started, so that time delay is reduced. Meanwhile, the problem that the first devices cannot synchronously transmit the space division due to different running time of the local scheduling flow can be avoided, and the first devices can start the air interface transmission after receiving the scheduling instruction transmitted by the second device, so that the first devices can synchronously transmit the space division, and the space multiplexing performance of a communication system is improved. In one possible design, the first scheduling result may include one or more of a scheduling number, a number of the first device, a number of users, a list of users, a minimum transmission duration, a scheduling request duration, a traffic identification TID number, or a TID delay.

In one possible design, the scheduling instructions include one or more of a scheduling number, a data frame transmission time, or a data frame transmission duration. Based on the possible design, based on the data frame sending time, each first device can synchronously send the data frame (or called message) to each terminal device, so as to improve the space multiplexing performance of the communication system. In addition, when determining the data frame transmission duration, the second device may determine, according to a minimum value of a plurality of minimum transmission durations in the plurality of first scheduling results, that the data frame transmission duration is greater than or equal to the minimum value of the plurality of minimum transmission durations. In one possible design, the method further comprises feeding back transmission result information to the second device, wherein the transmission result information comprises one or more of a scheduling number, a transmission result, the number of transmitted message protocol data unit MPDUs, a transmission duration, or a packet error rate.
