Method And Apparatus For Processing Information, Communications Device, And Communications System

Abstract

This application discloses a method and an apparatus for processing information, a communications device, and a communications system. The communications device is configured to obtain a starting position of an output bit sequence in a coded block in a circular buffer, and determine the output bit sequence in the coded block based on a length of the output bit sequence and the starting position. A value of the starting position is one of {p0, p1, p2 . . . , pkmax−1}, where 0≤pk<NCB, pk is an integer, k is an integer, 0≤k<kmax, NCB is a size of the coded block, and kmax is an integer greater than or equal to 4. Because a bit sequence for an initial transmission or a retransmission is properly determined, decoding performance of a communications device at a receive end after receiving the bit sequence is improved, a decoding success rate is improved, and a quantity of retransmissions is further reduced.
