<p num="1"><br/><br/><br/>A system, apparatus, and method are provided for dynamically selecting the <br/>data rate and/or transmit (TX) power. The method consists of devices <br/>periodically transmitting beacon frames in which they include data rate and/or <br/>TX power feedback for all senders of data streams, of which the devices are a <br/>receiver. The feedback may consist of recommended values for data rate and/or <br/>TX power or of channel state information. A sender chooses data rate and/or <br/>transmit power considering the feedback from the one or several receivers of <br/>the stream. The invention especially relates to systems based on an Ultra Wide <br/>Band Medium Access Control Protocol.<br/>
