Abstract:
A method for reducing the power consumption of a battery operated transceiver in standby mode, particularly a mobile telephone station, wherein successive word blocks are received by a receiver of the transceiver on a forward control channel, each word block consisting of a predetermined number of bits forming a dotting sequence, a word synchronization sequence and a predetermined number of word repeats, comprising the steps of switching off the receiver after a respective word repeat in a current word block has been validly received, and switching on the receiver to receive a corresponding word repeat in a next successive word block, wherein the receiver is switched on when a number of time pulses counted corresponds to a number of bits between an end of the respective word repeat in the current word block and a beginning of the corresponding word repeat in the next word block, wherein the time pulses correspond to bits that should have been received, had the receiver not been switched off, and the time pulses are generated by a clock generator in a free-running mode, said clock generator being brought into said free-running mode from a tracking mode, in which the clock generator tracks the bits received, when the receiver is switched off.
