摘要

[PROBLEMS] To decide the length of a guard interval based on the capability of a communication terminal apparatus. [MEANS FOR SOLVING PROBLEMS] A communication control apparatus (100), which adds a guard interval to symbols and transmits the symbols to a communication terminal apparatus, comprises a terminal information receiving part (120) that receives, from the communication terminal apparatus, delayed-waves-resistant performance information indicative of the performance of the communication terminal apparatus (200) dealing with delayed waves; a guard interval length deciding part (GI length deciding part) (140) that decides, based on the delayed-waves-resistant performance information, the length of a guard interval; and a data symbol transmitting part (150) that transmits, to the communication terminal apparatus (200), symbols to which the guard interval having the decided length has been added.
