Abstract
Aspects of the present disclosure relate to low density parity check (LDPC) encoding. At least a portion of the parity bits generated by an LDPC encoder for an initial transmission may be stored for use in generating subsequent hybrid automatic repeat request (HARQ) redundancy versions. In some examples, at least the degree-two and degree-three parity bits included in the initial transmission may be stored. The parity bits may be stored within a layer 2 (L2) or an upper layer buffer or within the LDPC encoder. For example, the parity bits may be stored within the HARQ buffer.
