Mobile device for power reduction and method thereof
A device and a method for saving power in a mobile electronic device are provided. A mobile electronic device includes a plurality of antennas and a transceiver, wherein the transceiver includes a control unit configured to switch to a low power mode to operate in the low power mode, or to operate at least one of the plurality of antennas in the low power mode when a data non-transmission period occurs for a predetermined time in an active state.
1. An electronic device in a wireless communication system, the electronic device comprising:
a plurality of antennas;
a transceiver; and
at least one processor operably coupled to the transceiver and configured to:
obtain, during a radio resource control (RRC) connected state, a result of a decoding of a control channel, and
operate at least one antenna for decoding a next control channel while maintaining the RRC connected state, after deactivating at least another antenna of the plurality of antennas based on the result of the decoding of the control channel.
2. The electronic device of claim 1 , wherein the at least one antenna is identified to be capable of decoding the next control channel from the plurality of antennas.
3. The electronic device of claim 1 , wherein the at least one processor is further configured to block a radio frequency (RF) path for the at least another antenna.
4. The electronic device of claim 1 , wherein the at least one processor is further configured to turn off a power to one or more RF components associated with the at least another antenna.
5. The electronic device of claim 1 ,
wherein the at least one processor is further configured to switch a first operation mode for decoding the control channel to a second operation mode for decoding the next control channel,
wherein the first operation mode is associated with the plurality of antennas, and
wherein the second operation mode is associated with the at least one antenna for decoding the next control channel.
6. The electronic device of claim 1 , wherein the at least one processor is further configured to:
in case that a decoding result of the next control channel is success, activate one or more deactivated antennas of the plurality of antennas.
7. The electronic device of claim 1 , wherein a signal quality provided by the at least one antenna is greater than a threshold for decoding the next control channel.
8. The electronic device of claim 1 , wherein the at least one processor is further configured to:
identify data non-transmission period based on the result, and
in case that the data non-transmission period reaches a certain time, deactivate the at least another antenna.
9. The electronic device of claim 8 , wherein the data non-transmission period is shorter than a period of an inactivity timer defined for switching from the RRC connected state to an RRC idle state.
10. The electronic device of claim 1 , wherein the next control channel comprises a physical downlink control channel (PDCCH).
11. A method performed by an electronic device in a wireless communication system, the method comprising:
obtaining, during a radio resource control (RRC) connected state, a result of a decoding of a control channel, and
operating at least one antenna for decoding a next control channel while maintaining the RRC connected state, after deactivating at least another antenna of a plurality of antennas based on the result of the decoding of the control channel.
12. The method of claim 11 , wherein the at least one antenna is identified to be capable of decoding the next control channel from the plurality of antennas.
13. The method of claim 11 , further comprising:
blocking a radio frequency (RF) path for the at least another antenna.
14. The method of claim 11 , further comprising
turning off a power to one or more RF components associated with the at least another antenna.
15. The method of claim 11 , further comprising:
switching a first operation mode for decoding the control channel to a second operation mode for decoding the next control channel,
wherein the first operation mode is associated with the plurality of antennas, and
wherein the second operation mode is associated with the at least one antenna for decoding the next control channel.
16. The method of claim 11 , further comprising:
in case that a decoding result of the next control channel is success, activate one or more deactivated antennas of the plurality of antennas.
17. The method of claim 11 , wherein a signal quality provided by the at least one antenna is greater than a threshold for decoding the next control channel.
18. The method of claim 11 , further comprising:
identifying data non-transmission period based on the result,
in case that the data non-transmission period reaches a certain time, deactivating the at least another antenna.
19. The method of claim 18 , wherein the data non-transmission period is shorter than a period of an inactivity timer defined for switching from the RRC connected state to an RRC idle state.
20. The method of claim 11 , wherein the next control channel comprises a physical downlink control channel (PDCCH).
