| 1. A method of managing communication, comprising the step of causing a central control station to schedule such that allowance
to transmit data is given, as a transmission right, to only one of communication stations in each time period by determining
a timing of transmitting data from a communication station that is to transmit the data, to a communication station that is
to receive the data, the method comprising the step of:
causing the central control station to carry out the scheduling at any time t, by using parameters C, TXOP bound, and T bound,
so that a sum of transmission right granted time periods actually granted in a time period {t0, t0+t} is always equal to or more than C·t−TXOP bound where t0 is an arbitrary time point, C is an average rate of change of the sum of the transmission right granted time periods allocated,
to the communication station that is to transmit the data, by the central control station according to a reference transmission
right allocation, and T delay is a maximum tolerable delay time of the data to be transmitted by the communication station
that is to transmit the data, C, TXOP bound, and T bound satisfying following formulas:
0≤T bound<T delay; Formula 1
0<C<1; and Formula 2
TXOP bound=C·T bound Formula 3.
