7. The electronic device of claim 1 , wherein the electric field state is identified based on a number of failures in decoding the reception signal.

8. The electronic device of claim 1 , wherein the communication processor is further configured to:

request the system information by a random access-related message, in a radio resource control (RRC) idle state.

9. The electronic device of claim 8 , wherein the communication processor is further configured to:

identify information broadcast from the base station,

identify random access-related information for transmitting the system information request included in the broadcast information, and

request the system information by a random access preamble based on the identified random access-related information.

10. An electronic device comprising:

a memory;

at least one antenna;

an application processor, and

a communication processor configured to:

receive an event related to an application from the application processor,

in response to the reception of the application-related event, identify a configuration of system information corresponding to the received event,

transmit a system information request corresponding to the received event to a base station through the antenna based on the system information corresponding to the received event being identified as set as non-broadcast information, and

receive the system information from the base station in response to the transmission of the system information request.

11. A method of operating an electronic device, the method comprising:

transmitting a system information request to a base station through at least one antenna;

in response to a failure in the system information request, identifying an electric field state of a reception signal;

setting a retransmission period of the system information request based on the identified electric field state of the reception signal; and

retransmitting the system information request based on the set retransmission period of the system information request.

12. The method of claim 11 , further comprising:

identifying information broadcast from the base station; and

identifying that the system information is set as information being transmitted by a request based on the broadcast information.

13. The method of claim 11 , wherein the electric field state is identified by a reference signal received power (RSRP) of the reception signal.

14. The method of claim 13 , further comprising setting the retransmission period based on a paging discontinuous reception (DRX) period and a transmission period of the system information based on the RSRP being a first threshold or more.

15. The method of claim 13 , further comprising:

setting the retransmission period to an integer multiple of the transmission period of the system information based on the RSRP being less than a first threshold and more than a second threshold, and

setting the retransmission period to the transmission period of the system information based on the RSRP being the second threshold or less.

16. The method of claim 13 , further comprising setting the retransmission period based on the RSRP being a first threshold or more to be larger than the retransmission period based on the RSRP being less than the first threshold.

17. The method of claim 11 , wherein the electric field state is identified based on a number of failures in decoding the reception signal.

18. The method of claim 11 , further comprising requesting the system information by a random access-related message, in a radio resource control (RRC) idle state.

19. The method of claim 18 , further comprising:

identifying information broadcast from the base station;

identifying random access-related information for transmitting the system information request included in the broadcast information; and

requesting the system information by a random access preamble based on the identified random access-related information.

20. A method of operating an electronic device, the method comprising:

receiving, by a communication processor, an event related to an application from an application processor;

in response to the reception of the application-related event, identifying a configuration of system information corresponding to the received event;

transmitting a system information request corresponding to the received event to a base station based on the system information corresponding to the received event being identified as set as non-broadcast information; and

receiving the system information from the base station in response to the transmission of the system information request.
