1. A wireless communication system, comprising:

  • a base station configured to transmit a signal as a downlink burst, the downlink burst including a portion modulated with a modulation technique; and

    a processor coupled to the base station and configured to receive, in an uplink transmission from a recipient node in response to a receipt of the downlink burst from the base station, a signal-to-noise ratio (SNR) measurement measured by the recipient node during the portion of the downlink burst, the portion addressed to one of a plurality of wireless nodes other than the recipient node, the processor further configured to determine, based on the received SNR measurement, whether a current preferred modulation technique of the recipient node should be changed for future downlink communication addressed to the recipient node.
