摘要：
A method and an apparatus are provided for receiving a transport block that is segmented into a plurality of code blocks (CBs), each CB having an attached cyclic redundancy check (CRC), decoding each of the plurality of CBs with attached CRC, determining whether each CRC fails, and in response to a determination that a CRC has failed, transmitting a CB index number of the CB attached to the CRC that has failed. Also provided are a method and an apparatus for a transmitter receiving an index number of a CB for retransmission (CBSIRT) attached with a CRC that has failed, determining the CB that correspond to the CRC that has failed based on the CBSIRT, and retransmitting the failed CB in a subsequent transmission time interval (TTI).
