METHOD AND DEVICE FOR DATA TRANSMISSION

摘要

Disclosed is a method for data transmission, which is used for reducing the overhead of a system. The method of the embodiments of the present invention comprises: a data packet sent by an access point (AP) to a station (STA) comprises resource scheduling information and a data field; the resource scheduling information comprises first indication information; the first indication information indicates that the data field comprises a first time block and a second time block; the first time block and the second time block respectively carry MAC frames, and both adopt the same physical parameter of a space-time stream for transmission; and the STA parses the MAC frames respectively carried by the first time block and the second time block. In this way, the transmission of different MAC frames in the same sub-band is realized, thereby improving the data exchange efficiency of an AP and an STA, and reducing the overhead of a system.
