摘要： A communication control apparatus in which, when requested to transmit (transmission) terminal information from information processing means, a transmission timing controller obtains past own terminal communication band information from an information storage, and determines whether or not to control a transmission timing. Moreover, the transmission timing controller calculates a back-off parameter for the control based on a past reception power information history that is obtained from the information storage, and sets a back-off parameter to a transmission device.
