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.
Claims16
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, 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.
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.
