Abstract:
This application discloses an information processing method, an apparatus, a communications device, and a communications system. The communications device is configured to: obtain a starting position in a buffer sequence W for an output bit sequence, and determine the output bit sequence from the buffer sequence W based on the starting position, where a value of the starting position is one element in {p 0 , p 1 , p 2 , . . . , p k max −1 }, 0≤k<k max , 0≤p k <N CB , p k  is an integer, k is an integer, N CB  is a length of the buffer sequence W, k max  is an integer greater than or equal to 4, and there are two or more different neighboring intervals in {p 0 , p 1 , p 2 , . . . , p k max −1 }. A bit sequence for initial transmission or retransmission is properly determined, so that decoding performance of a communications device on a receive end after receiving the bit sequence is improved, a decoding success rate is enhanced, and a quantity of retransmission times is further reduced.

Claim (Index 1):
A method of rate matching for a low-density parity-check (LDPC) code in a communications system, comprising:\n writing a bit sequence D into a buffer to obtain a buffer sequence W, wherein a length of the bit sequence D is K D  bits, and the bit sequence D is obtained after a bit sequence with a length of K bits is encoded based on a LDPC matrix; obtaining a starting position k 0  in a buffer sequence W for an output bit sequence, wherein a value of k 0  is p k , p k  is one element in {p 0 , p 1 , p 2 , . . . , p k max \u22121 }, 0\u2264k<k max , 0\u2264p k <N CB , N CB  is a length of the buffer sequence W, k max  is an integer greater than or equal to 4, and there are two or more different neighboring intervals in {p 0 , p 1 , p 2 , . . . , p k max \u22121 }; and determining the output bit sequence from the buffer sequence W based on the starting position k 0 .
