Claim Text:
1. A base station device comprising: a calculation unit that computes, based on subsequent information that is added to data from a terminal device and indicates presence or absence of untransmitted data which is reserved in the terminal device and is requested to be transmitted within a specific time when transmitting the data, a number of data in which the untransmitted data exists among a certain number of data previously transmitted from the terminal device; a time slot assignment control unit that previously stores a first threshold and a second threshold smaller than the first threshold, calculates a ratio of the data in which the untransmitted data exists in the terminal device based on the number of data, in which the untransmitted data exists, calculated by the calculation unit, extends the time slot to be assigned to the terminal device when the ratio of the data in which the untransmitted data exists exceeds the first threshold that is previously stored, and shrinks the time slot to be assigned to the terminal device when the ratio of the data in which the untransmitted data exists is less than the second threshold; a feedback control unit that changes a control parameter of the calculation unit and the time slot assignment control unit based on one or both of the subsequent information added to the data previously transmitted from the terminal device and assignment information of the time slot by the time slot assignment control unit, the control parameter including the certain number of the data previously transmitted from the terminal device; and a notifying unit that notifies the terminal device of the assigned size of the time slot determined by the time slot assignment control unit.
