Abstract
An encoding method and apparatus are provided. In the encoding method: encoding input information bits with an encoding matrix G and a linear combination formula. The encoding matrix G is an encoding matrix obtained by performing row permutation on an encoding matrix H having a plurality of successive zeroes in one or more columns of the encoding matrix H. Encoding control information with the encoding matrix provided by aspects of the present disclosure, each bit of the control information is distributed on all encoded output bits as uniformly as possible. Thereby, the bits of the control information obtain sufficient frequency diversity and time diversity after channel mapping, so as to improve transmission performance of the control information effectively.
