Method and apparatus for controlling power consumption in mobile communication system
First Claim
1. A method for controlling power consumption by a base station, the method comprising:
- selecting at least one duration of a plurality of durations in a subframe based on bitmap information indicating whether data is allocated to each of the plurality of durations in the subframe, each of the plurality of durations comprising at least one symbol;
performing a power amplifier (PA) off operation for the at least one duration based on the bitmap information when a length of the at least one duration is greater than a threshold,wherein the at least one duration comprises at least one empty symbol to which the data is not allocated, andwherein the threshold is determined based on a transient time according to an on/off operation of the PA.

Abstract
An embodiment of the present disclosure may provide a power consumption controlling method and apparatus. An embodiment of the present disclosure may provide a method and apparatus for controlling power consumption by a base station, the method comprising: determining empty symbol duration in at least one subframe; and performing a power amplifier (PA) on/off operation based on the determination result. Further, an embodiment of the present disclosure may provide a method and apparatus for controlling power consumption by a base station, the method comprising: generating baseband in-phase/quadrature-phase (IQ) data; determining whether the baseband IQ data includes data which must be transmitted for a predetermined time; and controlling a PA on/off based on the determination result and a transient of a power amplifier (PA).

7. A base station for adjusting power consumption, the base station comprising:
-
a power amplifier (PA) that amplifies a wireless signal; and a controller that selects at least one duration of a plurality of durations in a subframe based on bitmap information indicating whether data is allocated to each of the plurality of durations in the subframe, each of the plurality of durations comprising at least one symbol and controls a PA off operation for the at least one duration based on the bitmap information when a length of the at least one duration is greater than a threshold, wherein the at least one duration comprises at least one empty symbol to which the data is not allocated, and wherein the threshold is determined based on a transient time according to an on/off operation of the PA. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for controlling power consumption by a base station, the method comprising:
-
generating baseband in-phase/quadrature-phase (IQ) data; determining whether data to be transmitted for a predetermined time is included in the baseband IQ data; and controlling a power amplifier (PA) on/off based on the determination result and a transient time for changing from a bias off level to a bias on level of the PA, wherein, when the PA is turned on, a PA on operation is performed at a second time that precedes, by the transient time, a first time when the baseband IQ data is input in the PA. - View Dependent Claims (14, 15)

16. A base station for controlling power consumption, the base station comprising:
-
a power amplifier (PA) that amplifies a wireless signal; and a controller that generates a baseband in-phase/quadrature-phase (IQ) data, determines whether data to be transmitted for a predetermined time is included in the baseband IQ data, and performs a control such that a PA on/off is performed based on the determination result and a transient time for changing from a bias off level to a bias on level of the PA, wherein, the controller performs a control such that when the PA is turned on, a PA on operation is performed at a second time that precedes, by the transient time, a first time when the baseband IQ data is input in the PA. - View Dependent Claims (17, 18)
