Aspects of the invention include calculating, by a transmitter, source cyclic redundancy code (CRC) bits for payload bits. The source CRC bits include source CRC bits for a first type of CRC check and source CRC bits for a second type of CRC check. The source CRC bits are stored at the transmitter. The payload bits and the source CRC bits for the first type of CRC check are transmitted to the receiver. The receiver performs the first type of CRC check based at least in part on the payload bits and the source CRC bits for the first type of CRC check. The receiver also calculates and stores at the receiver calculated CRC bits for the second type of CRC check. If the first type of CRC check indicates an error, a comparison of the source and calculated CRC bits for the second type of CRC check is initiated.
