Abstract: A base matrix is applied to an LDPC coder. The base matrix includes multiple parts, each including multiple of rows and columns, and containing integers, each representative of an identity matrix cyclically shifted in accordance with the integer or representative of an all-zero matrix. At least two of the multiple parts are configured such that their respective column-wise combinations of rows represents a same starting vector, cyclically shifted or interleaved, with zero or more but not all integers not indicative of the all-zero matrix of the same vector substituted by integers indicative of the all-zero matrix. The at least two of the multiple parts are not identical. The applied base matrix is used for one of encoding data using the LDPC coder or decoding data using the LDPC coder.

Abstract: A method comprises receiving information on a selected redundancy version at a user device. The redundancy version is associated with block coding. The block coding may be LDPC. The method may comprise using the information when communicating with a base station. The position of the redundancy version may satisfy one or more criteria.
