<p>The invention concerns a radio transmission method for transmitting data in the form of successive frames (T) each comprising several data blocks (B). The frames are assembled by cycle of several successive frames and the blocks of each frame are assembled in subframes (ST). When a message is transmitted to a receiver, the initial addressing data concerning said receiver are always initially contained in the same subframe of certain frames, called listening subframe. The receiver stays for most of the time in sleep mode wherein it does not listen to the transmitted radio messages, and shifts, at the beginning of the subframe, into standby mode wherein it verifies if said listening subframe contains addressing data concerning it: if this is not the case it shifts back into sleep mode.</p> |
