A transmitting station in a radio network includes at least one radio frequency (RF) chain, a packet generator configured to generate a sounding packet including a number of training frames and a signaling frame, and at least one antenna element coupled to the at least one RF chain and configured to broadcast a transmit signal including the sounding packet. The packet generator produces in the sounding packet the number of training frames and the content of the signaling frame based at least in part on the number of antenna elements and the number RF chains.
