Abstract
A polar code construction method and an apparatus. A communication apparatus obtains a reliability weight sequence, and determines a first threshold that indicates a weight of lowest reliability of a subchannel corresponding to an information bit. The communication apparatus determines a non-pre-frozen subchannel corresponding to a content value greater than or equal to the first threshold in the reliability weight sequence as the subchannel corresponding to the information bit based on the first threshold, and performs polar coding on the information bit based on the subchannel corresponding to the information bit.
Claims19
A polar code construction method, comprising:
- obtaining, by a communication apparatus, a reliability weight sequence;
- determining, by the communication apparatus, a first threshold, wherein the first threshold indicates a weight of lowest reliability of a subchannel corresponding to an information bit;
- determining, by the communication apparatus, the subchannel corresponding to the information bit based on the first threshold, wherein the subchannel corresponding to the information bit is a non-pre-frozen subchannel corresponding to a content value greater than or equal to the first threshold in the reliability weight sequence;
- and
- performing, by the communication apparatus, polar coding on the information bit based on the subchannel corresponding to the information bit.
A communication apparatus, comprising:
- at least one processor, and the at least one processor is configured to run a computer program or instructions, to cause the processor to:
- obtain a reliability weight sequence;
- determine a first threshold, wherein the first threshold indicates a weight of lowest reliability of a subchannel corresponding to an information bit;
- determine the subchannel corresponding to the information bit based on the first threshold, wherein the subchannel corresponding to the information bit is a non-pre-frozen subchannel corresponding to a content value greater than or equal to the first threshold in the reliability weight sequence;
- and
- perform polar coding on the information bit based on the subchannel corresponding to the information bit.
A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores computer instructions or a program, and in response to the computer instructions or the program being run on a computer, the computer is enabled to:
- obtain a reliability weight sequence;
- determine a first threshold, wherein the first threshold indicates a weight of lowest reliability of a subchannel corresponding to an information bit;
- determine the subchannel corresponding to the information bit based on the first threshold, wherein the subchannel corresponding to the information bit is a non-pre-frozen subchannel corresponding to a content value greater than or equal to the first threshold in the reliability weight sequence;
- and
- perform polar coding on the information bit based on the subchannel corresponding to the information bit.
