<p>The present invention provides a communications method in a peer-aware communications system and transmission/reception devices using the same. According to the present invention, a transmission device generates a blocking signal for notifying channel occupation, and then transmits the blocking signal through a period in which a message signal including a preamble signal is not transmitted. A sub-carrier for transmitting the blocking signal is different from a sub-carrier for transmitting the preamble signal.</p> |
