Abstract:
1. An apparatus for generating transmission local oscillation signals and reception local oscillation signals in a mobile terminal, comprising: a first phase locked loop (PLL) block configured to generate a transmission local oscillation signal; a radio transmitter portion for receiving the transmission local oscillation signal; a second PLL block for generating a reception local oscillation signal; a radio reception portion for receiving the reception local oscillation signal; and a controller configured to control the first PLL block to operate before a minimum time period required for the first PLL block to lock up from the start point of a transmission burst period, to control the second PLL block to operate before a minimum time period required for the second PLL block to lock up from the start point of a reception burst period, to control the radio transmitter portion to operate only during a transmission burst period and to control the radio reception portion to operate only during a reception burst period.
