Method and apparatus for reducing electric power consumption of terminal in wireless communication system
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate compared to a 4G communication system such as an LTE. According to an embodiment of the present invention, a method performed by a terminal in a wireless communication system comprises the steps of: identifying, by a first processor of the terminal, a state of the terminal; transmitting the state of the terminal to a second processor of the terminal; identifying an electric power-related parameter associated with the state of the terminal; and transmitting, to a base station, a terminal message including the electric power-related parameter.
1. A method of a terminal in a wireless communication system, the method comprising:
identifying a state of the terminal,
identifying a power-related parameter associated with the state of the terminal, wherein the power-related parameter includes radio access technology (RAT) associated with the state of the terminal; and
transmitting a terminal message including information corresponding to the power-related parameter to a base station; and
receiving a new configured power-related parameter from the base station based on the transmitted terminal message and operating based on the received new configured power-related parameter;
wherein the operating comprises restricting use of a 5 th generation (5G) communication system when the state of the terminal is a power saving mode based on the received new configured power-related parameter.
2. The method of claim 1 , wherein receiving the new configured power-related parameter comprises receiving a message for reconfiguring the power-related parameter from the base station through radio resource control (RRC) signaling.
3. The method of claim 1 , wherein identifying a state of the terminal further comprises:
receiving configuration information about at least one power-related parameter from the base station;
estimating power consumption for each of the at least one power-related parameter;
associating each of the at least one power-related parameter with a state of the terminal; and
storing information about an association between each of the at least one power-related parameter and the state of the terminal.
4. The method of claim 1 , wherein identifying a state of the terminal further comprises detecting an input for the state of the terminal or identifying the state of the terminal according to a predetermined condition.
5. The method of claim 1 , wherein the state of the terminal is defined based on at least one of data throughput, battery state, or power saving mode.
6. A terminal in a wireless communication system, comprising:
a transceiver;
a processor configured to:
identify a state of the terminal;
identify a power-related parameter associated with the state of the terminal, wherein the power-related parameter includes radio access technology (RAT) associated with the state of the terminal;
transmit a terminal message including information corresponding to the power-related parameter to a base station;
receive a new configured power-related parameter from the base station based on the transmitted terminal message and operate based on the received new configured power-related parameter,
wherein the processor is further configured to:
restrict use of a 5 th generation (5G) communication system based on the received new configured power-related parameter when the state of the terminal is a power saving mode based on the received new configured power-related parameter.
7. The terminal of claim 6 , wherein the processor is further configured to
receive a message for reconfiguring the power-related parameter from the base station through radio resource control (RRC) signaling.
8. The terminal of claim 6 , wherein the processor is configured to receive configuration information about at least one power-related parameter from the base station, estimate power consumption for each of the at least one power-related parameter, associate each of the at least one power-related parameter with a state of the terminal, and store information about an association between each of the at least one power-related parameter and the state of the terminal.
9. The terminal of claim 6 , wherein the first processor is configured to detect an input for the state of the terminal or identify the state of the terminal according to a predetermined condition.
10. The terminal of claim 6 , wherein the state of the terminal is defined based on at least one of data throughput, battery state, or power saving mode.
