1. A communication terminal apparatus comprising:
- a memory configured to store a control program, anda processor configured to execute a control program and in response to executing the control program causes the communication terminal apparatus to perform operations, the operations comprising;
assigning a usage right of a first subframe, from among a plurality of subframes included in a frame, to a base station, in a case where terminal-to-terminal communication is performed by transmission and reception of the frame directly with a different communication terminal apparatus of a plurality of communication terminal apparatuses, based on frequency information reported from the base station and by selecting a configuration number from among a plurality of configuration numbers each indicating combinations which include a first combination between a third subframe of the plurality of subframes and a corresponding communication terminal apparatus of the plurality of communication terminal apparatuses which is allowed to use the third subframe, a second combination between a fourth subframe of the plurality of subframes and the base station which is allowed to use the fourth subframe, and a third combination between a fifth subframe of the plurality of subframes and information of a switching point; and
acquiring, during the terminal-to-terminal communication, information which the base station transmits in accordance with a timing when the communication terminal apparatus receives the first subframe corresponding to the fourth subframe specified by a selected configuration number using the information of the switching point specified by the selected configuration number.
