Communication system, terminal apparatus, and communication method

A first terminal apparatus that communicates with a second terminal apparatus, the first terminal apparatus comprising:

• a radio unit that transmits a first signal by using a first communication path that is a direct communication path to the second terminal apparatus,
• the radio unit receives a second signal transmitted by using a second communication path different from the first communication path, wherein
• the first signal is transmitted on a basis of a feature amount of the second signal, and
• a required transmission delay amount of data transfer using the first communication path is smaller than a required transmission delay amount of data transfer using the second communication path.

A first terminal apparatus that communicates with a second terminal apparatus, the first terminal apparatus comprising:

• a radio unit that transmits a first signal by using a first communication path that is a direct communication path to the second terminal apparatus,
• the radio unit receives a second signal transmitted by using a second communication path different from the first communication path, wherein
• the first signal is transmitted on a basis of a feature amount of the second signal, and
• a frequency resource used for the first communication path is allocated in advance.
