    Abstract: A base station and a method thereof for acquiring channel status information in a mobile communication system operating in a multiuser multiple-input multiple-output transmission mode are provided. The method includes generating and transmitting, to a terminal, interference measurement configuration information for measuring interference caused by signals transmitted from a serving base station of the terminal to at least one other terminal in the transmission mode; and receiving channel status information generated using the transmitted information from the terminal. The present disclosure relates to a communication method and system for converging a 5th-Generation communication system for supporting higher data rates beyond a 4th-Generation system with a technology for Internet of Things, and 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.

    Abstract: A method for transmitting and receiving a signal in a terminal of a mobile communication system, according to one embodiment of the present specification, comprises the steps of: receiving information of another terminal from the other terminal; transmitting, to a base station, a message requesting allocation of an identifier for the other terminal on the basis of the received information of the other terminal; and receiving, from the base station, the message including the identifier allocated for the other terminal. The provided present invention, according to one embodiment of the present specification, allows only the arbitrary receiver to access the base station and receive data therefrom when a plurality of densely located receivers are neighboring each other. At this point, the other receivers can selectively receive a data stream transmitted to each terminal from data channels received by the arbitrary receiver that accesses the base station. To this end, only the arbitrary terminal accessing at least the base station is enabled to allow feedback of the channel.

    Abstract: The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate after a 4G system and, and a system therefor. The present disclosure can be applied to intelligent services on the basis of 5G communication technology and IoT-related technology (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related service, etc.). When a particular frequency at which an LTE-A system operates is included in an unlicensed band, a situation may occur where some subframes of the LTE-A system cannot be used. When a synchronization signal and a discovery reference signal to be transmitted by a base station collide with a detection and channel occupation operation for the unlicensed band, the timing of the detection and channel occupation operation for the unlicensed band may be adjusted in order to solve the problem of the collision.

    Abstract: The present disclosure relates to a communication technique and system for combining IoT technologies with 5G communication systems to support a higher data rate after 4G communication systems. The present disclosure can be applied to intelligent services based on 5G communication technologies and IoT-related technologies such as smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail business, and security and safety. Provided are is a method and apparatus for supporting the licensed-assisted access (LAA) technology in a wireless communication system. The method for a user equipment (UE) may include: sending a first report message containing information on whether the LAA technology is supported to a base station (ENB) supporting a first communication technology; detecting usage of a second communication technology in a first band of the unlicensed spectrum; and sending, upon detecting usage of the second communication technology in the first band, a second report message containing information on usage of the second communication technology to the ENB.
