Abstract
A data message (201) is transmitted (301) to a plurality of communication units (103, 105, 107, and 109). The data message (201) is received (401) by the plurality of communication units, which determine (403) whether the quality of the received data message is acceptable. When at least one of the plurality of communication units determines that the received data message is of unacceptable quality, the at least one of the plurality of communication units transmits (411) an energy burst (203) in a predetermined time window. Upon detection of the energy burst (203), the transmitting device may retransmit (309) the data message to the plurality of communication units.
