A reception method comprising

• a group-wise deinterleaving step of returning a sequence of an LDPC code after group-wise interleaving to an original sequence, the sequence of the LDPC code after group-wise interleaving being obtained from data transmitted by a transmission method including:
• an encoding step of performing LDPC coding on a basis of a parity check matrix of an LDPC code with a code length N of 69120 bits and a coding rate r of 4/16;
• a group-wise interleaving step of performing group-wise interleaving that interleaves the LDPC code in units of bit groups of 360 bits;
• and
• a mapping step of mapping the LDPC code to any one of 16 signal points of a 16QAM 2D-non-uniform constellation (NUC) in units of 4 bits,
