Method and apparatus for low density parity check channel coding in wireless communication system

An apparatus for wireless communication, comprising at least one processor configured to:

• obtain an input sequence, wherein the input sequence comprises K bits, wherein K≥1;
• encode the input sequence using a matrix H to obtain an encoded sequence;
• and
• output the encoded sequence;
• wherein the matrix H is based on a base matrix and a lifting factor Z, wherein Z is a positive integer;
• wherein the base matrix comprises m rows and n columns;
• wherein each element in the base matrix corresponds to a respective row index i and a respective column index j, where 0≤i<m and 0≤j<n;
• wherein each element in the base matrix is either a zero-element or a non-zero-element;
• wherein the base matrix comprises at least the following rows:
• a first row corresponding to row index i=0 having non-zero-elements at columns corresponding to column indexes j=0, 1, 2, 3, 6, 9, 10, 11;
• a second row corresponding to row index i=1 having non-zero-elements at columns corresponding to column indexes j=0, 3, 4, 5, 6, 7, 8, 9, 11, 12;
• a third row corresponding to row index i=2 having non-zero-elements at columns corresponding to column indexes j=0, 1, 3, 4, 8, 10, 12, 13;
• and
• a fourth row corresponding to row index i=3 having non-zero-elements at columns corresponding to column indexes j=1, 2, 4, 5, 6, 7, 8, 9, 10, 13.
