METHODS AND APPARATUS FOR PROCESSING LDPC CODED DATA

Document Type and Number:

WIPO Patent Application WO/2019/047230

Kind Code:

A1

Abstract:

Methods and Apparatus for processing data encoded by low density parity check (LDPC) in a communication system are disclosed herein. In one embodiment, a method performed by a first node is disclosed. The method comprises: encoding an information bit sequence based on a base parity check matrix and a lifting size Z to obtain an encoded bit sequence; generating a master bit sequence based on the encoded bit sequence, wherein the master bit sequence includes Ncb bits, bit 0 to Ncb -1, that are selected from bits 2*Zto 2*Z+Ncb -1 in the encoded bit sequence; selecting a subset of the master bit sequence according to a rate matching rule to obtain a rate matched bit sequence; interleaving the rate matched bit sequence according to a predetermined index sequence to obtain a to-be-transmitted bit sequence; and transmitting the to-be-transmitted bit sequence to a second node.
