Abstract

When the mutual communications between a wireless base station (2) and a mobile communication terminal (1) are to be done conducted over the TDMA-TDD type wireless circuit, the setting of a data transfer direction at one or more slots is changed according to the amount of data to be transferred in a down-direction and/or an up-direction for each mobile communication terminal (1), thereby changing the circuit capacity of the down-circuit or up-circuit.
