Title:
SHIFT COEFFICIENT AND LIFTING FACTOR DESIGN FOR NR LDPC CODE
Document Type and Number:
WIPO Patent Application WO/2018/127196
Kind Code:
A1
Abstract:
Concepts and schemes pertaining to shift coefficient and lifting factor design for NR LDPC code are described. A processor of an apparatus may generate a quasi-cyclic-low-density parity-check (QC-LDPC) code and encode data using the selected codebook. In generating the QC-LDPC code, the processor may define a plurality of sets of lifting factors, generate a respective table of shift values for each lifting factor of the plurality of sets of lifting factors, and generate the QC-LDPC code using a base matrix and the shift coefficient table.
