Abstract

An embodiment of the invention provides data frame transmission method and device. By the use of the method and device, expense on data frames can be decreased and transmission efficiency can be increased. The method includes: determining a value of each bit ToDS (to distributed system) coming to a distributed system and a value of each bit FromDS (from distributed system) from the distributed system according to data transmission directional information of a site used for indicating transmission of data frames; acquiring an DA (destination address) and / or an SA (source address) corresponding to the data transmission directional information; determining an address field, which is used for carrying the DA and / or the SA, according to the data transmission directional information; determining an FCS (frame check sequence) of a data frame according to a header, a frame entity and an RA (received address) of the data frame; and transmitting the data frame comprising the ToDS, the FromDS, the address field and the FCS to a receiver. Using the address field to carry the DA and / or the SA of the data frame according to data transmission directional information decreases expense of frame headers and increases transmission efficiency, and transmission can be completed in the presence of data frame forwarding.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method and device for transmitting data frames. Background technique [0002] In some existing protocols, a data frame includes three parts, namely, a medium access control (MAC, Medium Access Control) frame header, a frame entity (Frame Body), and a 4-byte frame check sequence (FCS, Frame Check Sequence) domain, wherein the MAC frame header includes a 2-byte frame control (FC, Frame Control) field, a 2-byte duration / identifier (Duration / ID) field, an 18-byte address field, and a 2-byte In this way, the fixed overhead of the data frame (MAC frame header and FCS field) reaches 28 bytes. However, in the application scenarios of 802.11ah, the data packets are generally very short, for example, in the smart grid (SmartGrid), the shortest is only 25 bytes, so the overhead of the MAC frame header is relatively large. [0003] The existing method of compr...
