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 (TS0 and TM0 respectively). Each frame includes three time-slots, each intended for transmission and reception. According to the method, the frame structure is divided so that transmission (TX) first takes place in a transmission time-slot (TS0). Reception (RX) then takes places in a reception time-slot (TM0) which is separate from the transmission time-slot (TS0). Subsequent to reception (RX), the frame structure includes an idle time (t1) which remains until further transmission (TX) takes place in the next-following frame. The method enables the frequency synthesizer (FM) of the mobile in the reception direction to be set to a channel (fx) different to the reception channel (fm) and then to be reset accurately to the reception channel (fm). |
