    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for reducing latency for recovery from communications errors.SOLUTION: A message is transmitted as a first message portion transmitted at a first power level, and a second message portion, which is associated with the first message portion, transmitted at a second lower power level. The first power level is chosen to provide a predetermined probability that the first message portion will be successfully received. Alternatively, the first and second message portions are transmitted such that the first message portion has a greater energy per bit than does the second message portion. At a first time, the first message portion is received. At a second time, which has a known relationship to the first time, a signal is received from which the second message portion is not reliably obtained. A receiving device recognizes that the second message portion was not properly received and requests retransmission of at least the second message portion.
