A terminal device (102), used in communication system conducting communication by periodically switching frequency channels in a predefined sequence, communicating with a control device using a predefined channel, including: an antenna; a reception section receiving, from the control device (101), via the antenna, data and a beacon containing control information indicating the sequence and its timing; a transmission section transmitting data to the control device via the antenna; a data volume determining section determining whether a transmission is completable within a predefined period; and a control section controlling, within the period, the reception section to receive the data and the beacon, and the transmission section to transmit the data, and when the data volume determining section determines that the transmission is not completable, further controlling the transmission section to, determine a next-to-be-used channel based on the control information, switch to the channel after the period, and continue the transmission. |
