Data receiving method and apparatus

A data receiving apparatus, comprising:

• a front-end receiving module, configured to receive a data signal delivered by a base station, wherein the data signal comprises at least two encoded data block groups, each encoded data block group comprises at least one encoded data block, and encoded data blocks in each encoded data block group are transmitted in a binding manner;
• a decoding module, configured to decode the data signal, and acquire decoded data blocks obtained by decoding the encoded data blocks, to form corresponding decoded data block groups;
• and
• an interference cancellation module, configured to:
• separately perform cyclic redundancy check (CRC) detection on each decoded data block, and determine, according to a CRC, obtained through detection, of each decoded data block, whether to execute a successive interference cancellation (SIC) operation, and if it is determined to execute an SIC operation, execute CRC detection again on the decoded data block on which an SIC operation is performed, until a same CRC result occurs or all CRCs are zero, wherein at least one of the determining to execute an SIC operation according to the CRC of each decoded data block comprises:
• when CRCs of some decoded data blocks belonging to a decoded data block group are not zero, determining that the decoded data block is decoded incorrectly, and executing an SIC operation on the decoded data block.
