ABSTRACT:
A digital radiotelephone apparatus includes a personal station and a base station which communicate with each other by a radio signal using time division multiple access. The base station dynamically changes the transmission timing of control information, which is transmitted to the personal station, in a waiting state of the personal station. The personal station dynamically changes its reception timing of the control information in response to the dynamical change of the transmission timing by the base station.
