Modulation and coding scheme codes

A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:

• determining a frame of one or more frames, the frame having a header and a data payload, wherein the header comprises one or more fields, wherein at least one field of the one or more fields of the frame includes an indication of an modulation and coding scheme (MCS) index;
• determining a low-density parity-check (LDPC) code rate of 7/8 represented by a LDPC matrix comprising two rows and sixteen columns of elements, wherein each element represents a cyclic permutation matrix of size 42 by 42, wherein a first element, of the LDPC matrix, located at the first row and at the sixteenth column represents a zero matrix and a second element, of the LDPC matrix, located at the second row and at the sixteenth column has a value of 24;
• causing to send the frame to a first station device (STA) of one or more STAs using a modulation type associated with the MCS index.
