Communication Method, Communication Apparatus, and Computer-Readable Storage Medium

A communication method, comprising:

• receiving a symbol sequence;
• determining, based on a reliability sequence of length N2, a pre-frozen bit subchannel set, wherein a quantity of elements in the pre-frozen bit subchannel set is greater than or equal to 0, and wherein N2 is a positive integer;
• determining, based on a first reliability subsequence of length N in the reliability sequence, a first information bit subchannel set, wherein N is a positive integer, and wherein N is less than N2;
• determining, based on the reliability sequence and the pre-frozen bit subchannel set, a second information bit subchannel set;
• determining, based on a second bit subchannel subset in the second information bit subchannel set, a first bit subchannel subset in the first information bit subchannel set;
• and
• decoding, based on the first bit subchannel subset and the second bit subchannel subset, the symbol sequence to obtain a bit sequence.

An apparatus, comprising:

• a memory configured to store instructions;
• and
• one or more processors coupled to the memory and configured to execute the instructions to cause the apparatus to:
• determine, based on a reliability sequence of length N2, a pre-frozen bit subchannel set, wherein a quantity of elements in the pre-frozen bit subchannel set is greater than or equal to 0, and wherein N2 is a positive integer;
• determine, based on a first reliability subsequence of length N in the reliability sequence, a first information bit subchannel set, wherein N is a positive integer, and wherein N is less than N2;
• determine, based on the reliability sequence and the pre-frozen bit subchannel set, a second information bit subchannel set;
• determine, based on a second bit subchannel subset in the second information bit subchannel set, a first bit subchannel subset in the first information bit subchannel set;
• determine, based on the first bit subchannel subset and the second bit subchannel subset, a bit sequence;
• and
• perform polar encoding on the bit sequence to obtain an encoded result.
