The present disclosure relates to a sensor network, Machine Type Communication (MTC), Machine-to-Machine (M2M) communication, and technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method of providing a user interface (UI) by an electronic device is provided. The method includes displaying a control UI, receiving a first drag input via the displayed control UI, and, when a direction of the first drag input corresponds to a first direction, displaying a cursor UI at a preset location. According to an embodiment of the present disclosure, a UI through which an electronic device can easily receive a user input may be provided.

Method and apparatus for providing user interface

Provided are a method and apparatus for estimating and correcting the phase error in 5G or pre-5G communication systems providing much higher data rates compared to existing 4G communication systems including LTE systems. The existing phase error estimation scheme using a cyclic prefix in the time domain may fail to prevent performance degradation due to inter-carrier interference. In the present invention, it is possible to enhance reception performance of the receiver by estimating and correcting the phase error multiple times within a symbol using a time domain signal and by reducing the influence of inter-carrier interference.
