Abstract: Disclosed are an LDPC code-based communication method and a communication apparatus. Encoding or decoding may be performed based on a storage matrix and indication information. The indication information may include first information. Each row pair in a plurality of row pairs indicated by the first information includes two rows. A set of column numbers of columns in which non-zero elements in first x elements of a first row in the two rows are located is a proper subset of a set of column numbers of columns in which non-zero elements in first x elements of a second row in the two rows are located. In this way, split extension is implemented in a low-code-rate extension process, that is, elimination can be performed on the first row on a basis of adding the second row, to improve orthogonality between rows.

The terminal updates the first parameter and the second parameter at or before an earlier invalidation moment in the invalidation moment of the first parameter and the invalidation moment of the second parameter. The terminal determines a TA adjustment value based on an updated first parameter and an updated second parameter.
