Abstract: An electronic device may include a first communication processor supporting first network communication with a first network, and a second communication processor supporting second network communication with a second network different from the first network. When both of the first network communication and the second network communication are set to a data transmittable state, the second communication processor may be configured to transmit transmission data based on the second network communication selected as a primary path from between the first network communication and the second network communication, when the size of the transmission data is less than a predetermined threshold. In response to detection of a failure in the second network communication, the first communication processor may be configured to transmit the transmission data based on the first network communication, irrespective of whether the size of the transmission data is equal to or larger than the predetermined threshold.

Abstract: An electronic device includes a communication processor including a first communication circuitry, a second communication circuitry, and a temperature measurement sensor. The electronic device further includes an application processor that receives information via the second communication circuitry and determines whether to request the communication processor change modes. The communication processor receives a signal to change modes, release an RRC connection, and control the second communication circuitry to enter a sleep state.

Abstract: The present invention provides an electronic device for mitigating inter-cell interference in a dynamic TDD environment, the electronic device including: at least one antenna array including antenna elements; and a processor configured to use the antenna array and form a plurality of reception beams having mutually different directions, wherein at least one processor may enable: a first beam pair link to be formed with a first transmission beam emitted from a first base station by using a first reception beam having a first direction; information about a first TDD pattern indicating a TDD sequence set in a serving cell formed by the first base station and information about a second TDD pattern indicating a TDD sequence set in an adjacent cell adjacent to a serving cell formed by a second base station to be acquired; a first portion of the first TDD pattern to be selected on the basis of the information about the first TDD pattern and the information about the second TDD pattern; the detection of whether interference has occurred in the first portion; and a second beam pair link to be formed with one among transmission beams emitted from the second base station by using a second reception beam having a second direction different from the first direction, when the interference is determined to have occurred.
