Communication device and communication method

A communication method comprising:

• generating an aggregation frame in which a sequence of subframes is multiplexed in a time axis direction and a frequency channel axis direction;
• and
• wirelessly transmitting the transmission frame.

A communication device comprising:

• a reception unit that receives a wireless frame including an aggregation frame in which a sequence of subframes is multiplexed in a time axis direction and a frequency channel axis direction;
• and
• a construction unit that collects the subframes included in the aggregation frame received, and reconstructs a sequence of the subframes.
