1. A method of a transmitter in a mobile communication system, the method comprising:
- identifying at least one signal to be transmitted on a subframe;
determining a first bias level of a power amplifier (PA) of the transmitter, in case that user data is included in the at least one signal based on the identification;
determining a second bias level of the PA based on a type of the at least one signal, in case that the user data is not included in the at least one signal based on the identification; and
transmitting, to a receiver, the at least one signal on the subframe, based on the first bias level or the second bias level of the PA,wherein the second bias level is lower than the first bias level, andwherein the type of the at least one signal includes at least one of a reference signal, a synchronization signal, control information, and a signal for transmitting cell information.

Abstract
A method and apparatus of controlling transmission power in a transmitter of a wireless communication system are provided. The method includes generating a first signal to be transmitted to a receiver, identifying whether user data is allocated to the generated first signal, determining transmission power based on a result of the determination, and transmitting a second signal to the receiver, based on the determined transmission power and the first signal.

9. A transmitter of a mobile communication system, the transmitter comprising:
-
a transceiver configured to transmit and receive a signal; and at least one processor coupled with the transceiver and configured to; identify at least one signal to be transmitted on a subframe; determine a first bias level of a power amplifier (PA) of the transmitter, in case that user data is included in the at least one signal based on the identification; determine a second bias level of the PA based on a type of the at least one signal, in case that the user data is not included in the at least one signal based on the identification; and control the transceiver to transmit, to a receiver, the at least one signal on the subframe, based on the first bias level or the second bias level of the PA, wherein the second bias level is lower than the first bias level, and wherein the type of the at least one signal includes at least one of a reference signal, a synchronization signal, control information, and a signal for transmitting cell information. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
