Abstract
An apparatus and a method for controlling power consumption of a terminal in a wireless communication system are provided. The method includes deactivating one or more of hardware components for signal reception in a transmission interval if there is no data to be received in the transmission interval, and receiving a control signal by activating all the components in a next transmission interval.
Claims21
A method for operating a terminal in a wireless communication system, the method comprising:
- activating components for processing signals;
- receiving a control information through a physical downlink control channel (PDCCH) in a first period of a downlink subframe;
- and
- deactivating a subset of the components in a second period of the downlink subframe, based on a result of decoding the received control information, while maintaining an active mode.
7-9. (canceled)
A terminal in a wireless communication system, the terminal comprising:
- components for processing signals;
- at least one power supply circuit for the components;
- at least one processor configured to control to:
- activate components for processing signals,
- receive a control information through a physical downlink control channel (PDCCH) in a first period of a downlink subframe, and
- deactivate a subset of the components in a second period of the downlink subframe, based on a result of decoding the received control information, while maintaining an active mode.
A method for operating a terminal in a wireless communication system, the method comprising:
- receiving control information through a control channel in a first period of a transmission interval, wherein the transmission interval comprises the first period and a second period including a power controllable interval;
- deactivating a subset of components for signal reception in the power controllable interval of the transmission interval by using a plurality of control signals to change a state of each component in the subset of the components, if it is determined that there is no data to be received in the power controllable interval of the transmission interval based on the control information;
- and
- receiving another control information by activating the components for the signal reception in a next transmission interval,
- wherein a first component in the subset of the components is in a sleep state, and a second component in the subset of the components is in a power-off state in the power controllable interval of the transmission interval.
