Communication technology using low density parity check code base graph selection

摘要

Certain aspects of the present disclosure generally relate to techniques for selecting a base graph to be used for wireless communication. Selection can be based on a variety of factors. The base graph can be used to derive a low density parity check (LDPC) code used to encode the retransmission of the original transmission. The exemplary method encodes data bits in a code word based on modulation and coding scheme (MCS) and resource allocation (RA) for transmitting the codeword (e.g., bitstream such that some redundant bits are included in the codeword) Selecting a base graph (BG) from which to derive a low-density parity check (LDPC) code for use in encoding the data bits of the data, encoding the data bits to generate a codeword using the LDPC code derived from the selected BG And generally sending the codeword using the MCS over the RA's resources.
