    • A transmission method is used by a node of a communications network, wherein nodes communicate with one another via a carrier-sense multiple-access channel, said method comprising a step of sending a signal at a given transmit power and a given data rate to a receiver node over the channel, and wherein the transmit power of the sent signal assumes successively a first power value during a first time period and then a second power value during a second time period, the two power values being different and one of them being equal to the given power, the first time period representing the given power and the second time period representing the data rate. The invention also relates to a method of receiving a signal sent by the transmission method enabling the transmit power and the data rate used by the sender node to be deduced from the received signal.
    • 传输方法由通信网络的节点使用,其中节点经由载波侦听多址信道彼此通信,所述方法包括以给定的发射功率和给定的数据速率发送信号到一个 接收器节点,并且其中所发送的信号的发射功率在第一时间段期间连续地呈现第一功率值,然后在第二时间段期间呈现第二功率值,所述两个功率值是不同的,并且其中一个相等 给定功率,表示给定功率的第一时间段和表示数据速率的第二时间段。 本发明还涉及一种接收通过发送方法发送的信号的方法,其使得能够从接收到的信号推导出发送方节点使用的发送功率和数据速率。
