主权项

1. An apparatus, comprising:
a transmitter configured to transmit an outbound RF signal to a destination device, the outbound RF signal including a plurality of code words forming a transport block; a receiver configured to receive an Acknowledgement-Negative Acknowledgement (ACK-NACK) message from the destination device, wherein when one or more of the code words within the transport block were received in error by the destination device, the ACK-NACK message indicating the one or more code words that were received in error; and a processing module configured to determine the one or more code words that were received in error from the ACK-NACK message and retransmit the one or more code words that were received in error to the destination device via the transmitter.
