DATA TRANSMISSION METHOD, ACQUISITION METHOD, TRANSMISSION APPARATUS AND ACQUISITION APPARATUS

摘要

The present invention provides a data transmission method, acquisition method, transmission apparatus and acquisition apparatus, wherein, the data transmission method comprises: a first site encapsulates the data needed to be transmitted to a plurality of second sites into different protocol data units respectively, wherein the protocol data unit includes a protocol data unit of a media access control (MAC) layer and/or a protocol data unit of a physical layer; the protocol data unit encapsulated with data is cascaded in a wireless frame by the first site; the first site transmits wireless frames to a plurality of second sites. With the present invention, the problem of intense channel competition and large overhead during data transmission in related art is solved, so that the effect of reducing channel competition and reducing overhead is achieved.
