Apparatus, and an associated method, facilitates the efficient utilization of a channel extending between a sending and a receiving station of a digital communication system. A block of symbols to be transmitted by the sending to the receiving station is encoded utilizing a parallel-concatenated encoding technique. Selected encoded versions, or portions thereof, are transmitted by the sending station to the receiving station. The receiving station decodes the signals received thereat. If recovery of the informational content of the block of symbols cannot be effectuated, a request is made to transmit additional encoded versions, or portions thereof, of the block of symbols.
