Abstract: An electronic device for controlling at least one function based on a user input, and a control method for the electronic device are provided. According to various example embodiments, an electronic device that operates based on a user input may acquire a gesture through an input area of a display unit functionally connected to the electronic device. The electronic device may perform at least one function of the electronic device, based on various variables (for example, a time period for which the gesture is sensed, a size of an area in which the gesture is sensed, a direction in which the gesture moves, or intensity at which the gesture is sensed, through the input area) corresponding to the acquired gesture. Various other example embodiments are disclosed.

Abstract: Methods and apparatuses are provided for controlling reference signal (RS) transmission between a user equipment (UE) and a base station in a wireless communication system. A method includes transmitting, to the UE, downlink control information (DCI) including RS request information. The RS request information includes one or two binary elements based on a DCI format. If an RS transmission triggered by the RS request information is to occur in a same subframe as another RS transmission previously configured to the UE from the base station, the UE transmits the RS triggered by the RS request information.
