Abstract: An operating method of a base station includes performing channel estimation on a plurality of user equipment (UEs) based on a plurality of sounding reference signals (SRSs), allocating a first frequency resource and a second frequency resource based on a result of the channel estimation, the first frequency resource and the second frequency resource corresponding to a first UE among the plurality of UEs, and a rank value of the first frequency resource being different from a rank value of the second frequency resource, and transmitting an uplink grant to the first UE, the uplink grant including a plurality of resource block group (RBG) bitmaps to the first UE.

Abstract: Provided is a method of operating an electronic device, the method including receiving, from a base station, a downlink control signal requesting repeated transmission of an uplink signal, determining a repeated transmission mode for changing at least one of a precoding matrix, an analog transmission beam, and transmission power of the uplink signal when the uplink signal is repeatedly transmitted in response to reception of the downlink control signal, and repeatedly transmitting a plurality of uplink signals according to a determined repeated transmission mode.

Abstract: A smart watch, which simultaneously provides the two functions of a physical watch and a mobile terminal, and a method for controlling the same are disclosed. The present invention provides a smart watch and a method for controlling the smart watch, the smart watch comprising; a case; at least one hand for displaying current time, the at least one hand being arranged to be adjacent to the inner periphery of the case; a movement for moving the hand along the inner periphery of the case, the movement being located inside the case; and a display unit configured to display various types of information, the display unit being located in the case, wherein the hand and a screen of the display unit are simultaneously shown to a user.

Abstract: In a mobile terminal, according to one embodiment of the present invention, for achieving the object as above, a wireless communication unit, a touch screen and a control unit cooperate with each other to perform a message transmission function. The control unit performs the message transmission function through a step of controlling the touch screen to output a message written by a user input; a step of outputting, in the case where the message includes content related to a file attachment, one or more files that can be attached to the message in a selectable link form using the content related to the file attachment; and a step of attaching, if at least one is selected from among the one or more files outputted in a link form, the at least one selected file to the message.
