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