Classification: CPC H | IPC H

Claim 8:
9. A first node for producing a set of coded bits from a set of information bits for transmission to a second node in a wireless communications system, the first node comprising:
processing circuitry, the processing circuitry configured to:
generate a codeword vector by encoding the set of information bits with a low-density parity-check code that is specified through a parity check matrix; and
puncture a multiple of Z of the information bits from the codeword vector before writing the codeword vector into a circular buffer, where Z is a lifting factor of the parity check matrix and where the punctured multiple of Z bits have a higher column weight than non-punctured bits; and
perform circular buffer-based rate matching on the punctured codeword vector to produce the coded bits for transmission.
