A method for dividing a frame structure for a mobile telephone system which operates in half-duplex, i.e. in which the transmission and reception of signals in a mobile takes place within mutually separate time-slots. Each frame includes three time-slots, each intended for transmission and reception. According to the method, the frame structure is divided so that transmission first takes place in a transmission time-slot. Reception then takes places in a reception time slot which is separate from the transmission time-slot. subsequent to reception (RX), the frame structure includes an idle time (t1) which remains until further transmission takes place in the next-following frame. The method enables the frequency synthesizer of the mobile in the reception direction to be set to a channel different to the reception channel and then to be reset accurately to the reception channel.
