Abstract
In a TDMA type cellular mobile radio system frequencies are shared between cells of the same re-use pattern and frequency hopping is used so that the frequency used at any time in one of the cells of a re-use pattern is different from those used at the same time in the other cells of that pattern. A base transceiver station of this system commands the sending of one of the frequencies shared in this way during a part of the time division multiple access frame and commands the stopping of all sending during the other part of the frame. This other part of the frame has a duration at least equal to the relative synchronization error between base transceiver stations of the system
