Wireless communication using codebooks from a QC-LDPC code for shorter processing latency and improved decoder throughput efficiency

A method of wireless communication, comprising:

• selecting, by a processor of an apparatus, a codebook from a plurality of codebooks embedded in a quasi-cyclic-low-density parity-check (QC-LDPC) code;
• storing, by the processor, the selected codebook in a memory associated with the processor;
• encoding, by the processor, data using the selected codebook to generate a plurality of modulation symbols of the data;
• and
• controlling, by the processor, a transmitter of the apparatus to multiplex, convert, filter, amplify and radiate the modulation symbols as electromagnetic waves through one or more antennas of the apparatus,
• wherein the selecting of the codebook from the plurality of codebooks embedded in the QC-LDPC code comprises selecting the codebook according to one or more rules such that a small codebook requiring a shorter amount of processing latency for the encoding is selected for the encoding unless a larger codebook corresponding to a larger amount of processing latency for the encoding is necessary for the encoding.
