A method may comprise transmitting a first signal derived from a first subset of a set of LDPC coded bits and transmitting a second signal derived from a second subset of the set of LDPC coded bits. The second subset may be selected from the set of LDPC coded bits based on a lifting size of an LDPC base graph. The method may further comprise receiving an indication of a first redundancy version. The transmitting the first signal may be in response to receiving the indication of the first redundancy version.
