1. A communication control apparatus for controlling communication by repeatedly sending a control signal to other apparatuses at a given time interval, the communication using a protocol that regulates transmissions of an acknowledgement as a receipt for one or more communication packets, and the control signal allocating, within the given time interval, two types of communication periods which are (i) a one-way communication period in which a one-way communication is performed and (ii) a two-way communication period in which a two-way communication is performed, the communication control apparatus comprising: a storing unit in which an occurrence ratio of the transmissions of the acknowledgement is stored; a determination unit operable to determine, based on the stored occurrence ratio of the transmissions of the acknowledgement, a length of the one-way communication period; and a communication control unit operable to generate and send the control signal that allocates a plurality of the one-way communication periods each of which has the determined length.
