Abstract

See full text

Methods and apparatus for successive interference cancellation (SIC). In an embodiment, a method includes receiving symbols from a plurality of user equipment (UE), identify a target UE and non-target UEs, decoding code blocks from the symbols received from the non-target UEs to generate decoded bits for each code block. The method also includes performing a CRC check on each code block to generate a tag (0) when the CRC check passes and a tag (1) when the CRC check fails, and re-encoding the decoded bits to generate re-encoded code blocks having the associated tags attached. The method also includes reconstructing symbols from the re-encoded code blocks where symbols reconstructed from re-encoded code blocks having tag (0) are reconstructed with data and symbols reconstructed from re-encoded code blocks having tag (1) are reconstructed as zero value symbols, and utilizing the reconstructed symbols to cancel interference on symbols from the target UE.
