A generation device generates a frame to be transmitted to a destination
communication apparatus. The frame includes a first separation field, a
first MAC protocol data unit (MPDU) following the first separation field,
a second separation field following the first MPDU, a third separation
field following the second separation field, and a third MPDU following
the third separation field. The second separation field includes length
information set to a value of zero to indicate no second MPDU directly
follows the second separation field. The first MPDU includes a first MAC
header, a first data field, and a first frame check sequence (FCS). The
first FCS is for detecting an error occurred in at least the first data
field. The third MPDU includes a third MAC header, a third data field,
and a third FCS. The third FCS is for detecting an error occurred in at
least the third data field.
