The disclosure relates to a 5generation (5G) or 6generation (6G) communication system for supporting higher data transmission rates than 4th generation (4G) communication systems, such as long-term evolution (LTE) systems. A method and a device are provided. The method includes, by a user equipment (UE) in a wireless communication system, receiving RIS information from an RIS controller (RC), identifying an incident beam incident on the UE, providing information about the identified incident beam to the RC and requesting information about candidate RIS modes, receiving the information about the candidate RIS modes, performing probing on the candidate RIS modes, deriving a final RIS mode among the candidate RIS modes using a result of the probing, and transmitting information about the final RIS mode to an RIS through the RC.

Method and device for RIS automatic setup

Methods and apparatuses for remotely installing Universal Integrated Circuit Card (UICC) information about various Mobile Network Operators (MNOs) are provided. One of the apparatuses being a terminal including an electronic card, a transceiver configured to transmit and receive a signal, and a controller configured to receive at least one profile from a profile management server, wherein each profile of the received at least one profile is to be installed in an electronic card of at least one device, to obtain at least one electronic card identifier of the at least one device, and to transmit, to the at least one device, the at least one profile corresponding to the obtained at least one electronic card identifier.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A terminal is provided, which includes a sensing unit configured to collect authentication information; and a control unit configured to perform the authentication based on first authentication information and second authentication information, to control the sensing unit to collect third authentication information if it is determined that the authentication based on the first authentication information has succeeded and the authentication based on the second authentication information has failed, and to perform the authentication based on the third authentication information. Since the authentication is performed through a combination of biometric information and context information that are acquired from two or more terminals, reliability and security of the authentication can be heightened.

The inventive concepts provide a solar cell and a method of fabricating the same. The method includes preparing a substrate in a chamber, forming a light absorbing layer on the substrate by setting temperature in the chamber to a first temperature and by supplying a first source into the chamber, forming a buffer layer on the substrate by setting temperature in the chamber to a second temperature lower than the first temperature and by supplying the first source into the chamber, and forming a window layer on the substrate by supplying a second source different from the first source into the chamber.
