Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/KR2022/002449 designating the United States, filed on Feb. 18, 2022, in the Korean Intellectual Property Receiving Office and claiming priority to Korean Patent Application No. 10-2021-0056914, filed on Apr. 30, 2021, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties. FIELD The disclosure relates to an electronic device for performing an operation corresponding to an over-temperature state and a method of operating the same. DESCRIPTION OF RELATED ART In order to satisfy the increasing demand of radio data traffic after commercialization of a 4G communication system, a 5G communication system is being developed. The 5G communication system is being considered for implementation to use not only the conventionally used communication bands like those used by 3G and LTE but also a new band, for example, an ultra-high frequency band (for example, FR2 band) to achieve a high data rate. A plurality of antenna modules may be packaged into an electronic device supporting mmWave that is the ultra-high frequency band. A radio channel in mmWave has high straightness and large path loss due to a high frequency characteristic, and a highly directional beamforming technology is necessary to compensate therefor and a plurality of antenna modules are needed for the highly directional beamforming. For example, the electronic device may mount a plurality of antenna modules radiating signals in different directions. A 5G communication technology may transmit a relatively large amount of data and consume higher power, and thus may potentially increase the temperature of an electronic device. For example, the electronic device cannot avoid consuming more current due to an increase in the use of a high frequency band and data throughput, and an antenna module being used or a peripheral area thereof may be over-heated according to an increase in heating. When a specific antenna module or a peripheral area thereof is over-heated, a user using the electronic device may be unpleasant and may suffer from a low-temperature burn. Components (for example, a battery) disposed close to the over-heated antenna module may have additional damage and also the overall performance of the electronic device may deteriorate. Further, the electronic device may be used after installation of various applications including a data transmission/reception function through 5G communication. When an application having an excessive amount of data transmission/reception through 5G communication is executed, the electronic device may further increase the heating due to an increase of the use of a high frequency band and data throughput. SUMMARY Embodiments of the disclosure provide an electronic device and a method of operating the which may perform only an operation which does not require a link with a network or change a UE capability along with the operation which does not require the link with the network based on the current state of at least one parameter of the UE capability in the over-temperature state.
