A computer-implemented method is proposed for coordinating communication amongst wireless communication devices in a wireless network. The coordination scheme creates a side channel between heterogeneous wireless devices to enhance their cooperation. At the transmitter, the coordination scheme appends a customized preamble to a data payload, where the preamble is comprised of a sequence of energy pulses separated by a gap and the duration of the gap encodes coordination data for the receive device. At the receiver, the coordination scheme detects the preamble of the data packet; extracts the coordination data from the preamble of the data packet; and coordinates communication between the transmit device and the receive device using the coordination data.
