Abstract

A transceiver includes a receiver that receives and demodulates a first encoded block of data. The first encoded block of data includes a first redundancy version that corresponds to a first payload portion and a first header portion. The first encoded block of data is received from a communication device that is remote from the transceiver and that is in a cellular telecommunication network. A transmitter transmits an acknowledgement/negative acknowledgement (ACK/NACK) signal that includes a dedicated decoding status indicator for the header portion.
