Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. A communication apparatus, comprising:
a processor, configured to generate a second codeword, wherein a puncturing pattern of the second codeword is generated based on a puncturing pattern of a first codeword, the puncturing pattern of the first codeword comprises a first puncturing location set, the puncturing pattern of the second codeword comprises a second puncturing location set, and the second puncturing location set is a subset of the first puncturing location set; and
a transceiver, configured to send the second codeword,
wherein the first codeword corresponds to a first code rate, the second codeword corresponds to a second code rate, either the first code rate or the second code rate is a code rate in Table A, the first puncturing location set comprises a first puncturing location corresponding to the first code rate in Table A and all puncturing locations located before the first puncturing location in Table A, and the second puncturing location set comprises a second puncturing location corresponding to the second code rate in Table A and all puncturing locations located before the second puncturing location in Table A; and
Table A is shown as follows:, TABLE A
