METHOD, APPARATUSES AND SIGNAL FOR TRANSMITTING/RECEIVING INFORMATION COMPRISING PRIMARY AND SECONDARY MESSAGES IN A SAME TRANSMISSION
摘要
<p>Transmitters ( 116 ) for transmitting information and receivers ( 126 ) for receiving the information are defined by the information comprising a primary message and a secondary message combined in a same transmission or a same reception, which primary and secondary messages comprise communication protocol signaling messages, to avoid that a protocol conversion arrangement needs to be added to and to be placed between the transmitter ( 116 ) and the receiver ( 126 ). This increases the efficiency of the transmitter ( 116 ) and the receiver ( 126 ). The primary and secondary communication protocol messages are in accordance with first and second standards such as 802.11 a and later standards such as 802.11 n. The receiver ( 126 ) is able to detect the primary or secondary communication protocol message in case of the receiver ( 126 ) being in accordance with the first or second standard. The secondary message is embedded in the primary message via a modulation or via a selection of a subset of a set of a modulation constellation.</p>
